اوباما: آمریکا و فرانسه در برابر ایران متحدند

باراک اوباما، رئیس جمهوری آمریکا و نیکولا سارکوزی، رئیس جمهوری فرانسه بر جلوگیری از دستیابی ایران به تسلیحات هسته ای تاکید کردند.

اوباما سه شنبه دهم فروردین (۳۰ مارس) در کنفرانس خبری مشترکی با سارکوزی در کاخ سفید ابراز امیدواری کرد تحریم های بین المللی علیه ایران در بهار امسال افزایش یابد.

او گفت قصد ندارد ماه ها برای وضع مجموعه ای از تحریم ها صبر کند، بلکه می خواهد چنین امری طی چند هفته تحقق یابد.

ایران برنامه اتمی خود را صلح آمیز می داند و می گوید تحریم های غرب بر خط مشی اتمی این کشور اثری نخواهد گذاشت.

رئیس جمهوری آمریکا گفت موضع ایالات متحده و فرانسه درباره تحریم ایران واحد و “جدایی ناپذیر” است.

او اذعان کرد قدرت های بزرگ هنوز درباره تحریم ایران موضع واحدی ندارند. چین، عضو دائم شورای امنیت با افزایش تحریم ها علیه ایران مخالف است.

اوباما بدون این که به چین اشاره کند، گفت ایران یک کشور تولید کننده نفت است و بسیاری از کشورها حاضرند که روابط تجاری خود با این کشور را حفظ کنند و به همین دلیل آمریکا باید بر دیگر کشورها نیز در رابطه با تحریم ایران فشار وارد کند.

رئیس جمهوری فرانسه هم در این کنفرانس خبری بر تشدید تحریم ها علیه ایران تاکید کرد. او گفت: “زمان اتخاذ تصمیم فرا رسیده است.”

هشدار گروه هشت

از سوی دیگر، وزیران امورخارجه هشت کشور بزرگ صنعتی جهان در پایان نشست خود در کانادا از ایران خواستند غنی سازی اورانیوم را متوقف کند یا برای تشدید تحریم های بین المللی آماده شود.

بر اساس بیانیه پایانی نشست وزیران امورخارجه گروه ۸، هشت کشور صنعتی ضمن تاکید بر ادامه گفتگوهای هسته ای با ایران، از جامعه بین المللی خواسته است برای نشان دادن یکپارچگی خود در مقابل این کشور، تدابیر قوی و موثری را اتخاذ کنند.

این بیانیه همچنین از ایران خواسته است قطعنامه های شورای امنیت درباره توقف غنی سازی اورانیوم را به اجرا بگذارد و با آژانس بین المللی انرژی اتمی همکاری بیشتری داشته باشد.

در این بیانیه آمده است: “وزیران خارجه (گروه ۸) توافق کردند گفتگوها ادامه پیدا کند و همچنین بر ضرورت اقدام مناسب و قوی جامعه بین المللی برای نشان دادن عزم خود برای حفاظت از پیمان عدم گشترس سلاح های اتمی تاکید کردند.”

اعضای غربی گروه ۱+۵ که از اعضای دایمی شورای امنیت و آلمان تشکیل شده است، خواستار تشدید تحریم های ایران برای افزایش فشار بر این کشور با هدف توقف غنی سازی اورانیوم در این کشور هستند.

عفو بين الملل: ايران با اعدام دست کم ۳۸۸ نفر در سال ۲۰۰۹ بعد از چين در بالاترين مرتبه قرار گرفت

VOAPPN;

سازمان عفو بين الملل که سازمانی مدافع حقوق انسانی است گزارشِ مربوط به اعدام ها و مجازات های صادر شدۀ مرگ را در سال ۲۰۰۹ در جهان، منتشر ساخته است.

در گزارش عفو بين الملل آمده است ايران با اعدام دست کم ۳۸۸ نفر در سال ۲۰۰۹ بعد از چين در بالاترين مرتبه قرار گرفته است. جمهوری اسلامی ايران معمولاً آمار دقيقی از اعدام شدگانِ کشور را اعلام نمی کند.

عفو بين الملل همچنين اعلام کرده است که ۱۱۲ نفر از کسانی که سال گذشته در ايران اعدام شدند تنها در فاصلۀ چند هفته پس از انتخابات ۲۲ خرداد ماه تا برگزاری مراسم تحليف دومين دورۀ رياست جمهوری محمود احمدی نژاد، اعدام شده اند.

بنابر گزارش سازمان عفو بين الملل در سال ۲۰۰۹ دو کشورِ ايران و عربستان سعودي به اعدام نوجوانان زير هجده سال ادامه داده اند. اعدام جوانان زير ۱۸ سال خلافِ موازين بين المللی ست.

آنتی بیوتیک، خطر مرگ مبتلایان به اچ آی وی/ ایدز را کاهش می دهد

VOAPNN

یک تحقیق جدید پزشکی درباره بیماران مبتلا به اچ آی وی/ ایدز در آفریقا می گوید اگر بیماران آنتی بیوتیک مصرف کنند، خطر مرگ در مراحل اولیه بیماری به شکل چشمگیری کاهش می یابد.

به گفته این تحقیق بیماران مبتلا به اچ آی وی/ ایدز که علاوه بر داروهای ضد ویروس، آنتی بیوتیک کو- تریموکسازول مصرف می کنند، ۵۹ درصد کمتر از دیگر بیماران در سه ماه اول ابتلا در خطر مرگ قرار دارند.

محققان در این مطالعه پزشکی ۳۱۷۹ بیمار بالغ در اوگاندا و زیمبابوه را مورد مطالعه قرار دادن که سال های ۲۰۰۳ و ۲۰۰۴ در این تحقیق مشارکت کردند. این مطالعه توسط کالج امپریال لندن یا کنسول تحقیقات پزشکی در بریتانیا و مراکز پزشکی در اوگاندا و زیمبابوه انجام شده است.

محققان می گویند نتایج به دست آمده ارائه آنتی بیوتیک به تمامی مبتلایان بالغ در آفریقا دست کم برای سه ماه اول درمان آنان را تقویت می کند. سازمان بهداشت جهانی از این اقدام استقبال کرده است.

12 ways to cut your taxes

Posted on 28 March 2010 by admin

12 ways to cut your taxes

The bright spot of the dreary 2009 economy: savings for everyone.

CNNMoney.com

1 . You bought a house

Late last year, Congress extended the valuable homebuyer break beyond first-timers. So if you already owned a home but bought a new one after Nov. 6, 2009, you may be entitled to a credit worth 10% of the purchase price, up to $6,500.

Even if you buy in 2010 — you have until April 30 to sign a contract and until June 30 to close — you can claim the credit on your 2009 return, says Mark Luscombe, a principal analyst with tax research firm CCH. (You may need to file an extension or amended return if you sign after April 15.)

The fine print: You have to have lived in your old home for five consecutive years of the past eight. Plus, the new home must be your principal residence and must have cost $800,000 or less. Of course, first-time homebuyers also benefit, with a credit of 10% of the price up to $8,000. So if a child or someone else you know finally kicked the renting habit in 2009 — or plans to in early 2010 — have him or her check irs.gov for dates and income restrictions.

Income Limits (for repeat homebuyers)
Full credit up to $225,000
Partial credit up to $245,000

Potential savings: $6,500 for a repeat homebuyer on a house worth $65,000 or more

2. You’ve got a kid in college

New for 2009 and 2010, the American Opportunity Tax Credit “will typically be the most generous of the education credits,” says John Roth, a senior analyst with CCH. With it, you can claim $2,500 per student per year for the first four years of college.

Still on the books are the Hope Credit, which provides $1,800 per student for the first two years of college, and the Lifetime Learning Credit, which offers up to $2,000 per return. But you can’t take more than one of them in any given year for any one student. So most people should go with the more valuable AOTC, which also has higher income caps.

Income Limits
Full credit up to $160,000
Partial credit up to $180,000

Potential savings: $2,500 per student

3. You got a new set of wheels

If you bought a new car, light truck, motor home, or motorcycle after Feb. 16, 2009, you can deduct the sales taxes you paid on up to $49,500 of the vehicle’s price. You don’t need to itemize to take this special one-year write-off — making it especially valuable for high earners who typically have their itemized deductions clipped or who might otherwise get hit by the alternative minimum tax (AMT). Traded in a junker through the Cash for Clunkers program? Lucky you, you can take this break too.

If you normally opt to deduct your sales taxes in lieu of state and local taxes on your Schedule A — a choice made by many people in low-income tax states — you would have been allowed to write off auto sales taxes anyway. But you should run the numbers to see if you’d be better off using this new provision vs. itemizing, as many itemized deductions are subject to being added back in with the AMT.

Income Limits
Full break up to $250,000
Partial break up to $260,000

Potential savings: $420 on a $30,000 car in a state with a sales tax of 5%

4. You were out of work

More than 5 million U.S. jobs disappeared in 2009, according to the Bureau of Labor Statistics. Yours was one of them? You can use your 1040 to soften the hard times if …

You collected unemployment: This income is usually taxable, but for 2009 only, the first $2,400 of it is tax-free, says Mark Steber of Jackson Hewitt. Households in which both spouses collected unemployment can exclude $4,800. So if you chose to have taxes taken out of your weekly benefits, you “may end up getting a better-than-expected refund,” says CCH’s Luscombe.

Potential savings: $672 per recipient

You looked for a job: As long as you’ve been seeking work in the same field as your last position, your expenses — including those for travel, career coaching, and résumé services — qualify as miscellaneous deductions, and you can write them off to the extent that they (combined with other deductions like safe-deposit fees) exceed 2% of your adjusted gross income (AGI). You can take this break even if you weren’t out of work.

Potential savings: $840 if you had a $140,000 income and $5,800 in these and other miscellaneous expenses

You paid the full tab for health insurance: Most taxpayers don’t have enough out-of-pocket medical expenses to meet the steep threshold for deducting them: You can write off these costs only to the extent that they exceed 7.5% of your AGI. But if you were out of work last year and had to pay for COBRA or other health insurance, there’s a good chance those costs may have put you over the limit — especially if your income fell too. (The average family paid $4,776 for COBRA last year, even with the subsidy that was part of the economic relief package, according to data from the Kaiser Family Foundation.) Aspirin and eyeglasses count toward the write-off; see IRS publication 502 for a list of other qualifying expenses.

Potential savings: $132 if your income was $70,000 and you paid average COBRA costs plus another $1,000 in medical bills

5. You helped those in Haiti

Though the earthquake occurred in 2010, you don’t have to wait until next year to deduct your contributions to nonprofits providing disaster relief. Congress fast-tracked a bill that lets you deduct donations made before March 1, 2010 on your 2009 tax return. A bill is currently in the House that would enable taxpayers to deduct last-minute donations to Chile earthquake relief from their 2009 returns as well.

Potential savings: $56 for giving $200 to Haiti relief

6. You had investment losses

Even with the market’s surge last year, the average stock was still down 29% from its October 2007 peak. If you sold securities at a loss in 2009 and you had owned the shares for more than a year, those losses can come in handy now. You can use them, as well as any losses you carried over from 2008, to offset capital gains you may have reaped by selling investment winners as the markets recovered. Have more losses than gains? You can also use up to $3,000 in net investment losses to offset ordinary income. And any leftover losses can be carried forward to reduce your 2010 taxes.

Potential savings: $840, assuming $3,000 in losses and no capital gains

7. You weathered a disaster

There were 59 federal disasters declared in 2009, everything from ice jams in Alaska to flooding in Florida. If your house was damaged in one of them and your homeowners insurance didn’t pick up the full bill, you have money coming back to you — and you don’t need to itemize to get it. For 2009, there is no limit on what you can claim (typically you can deduct only losses greater than 10% of AGI). And you can also retroactively apply any losses you can’t use to 2008 taxes. File amended returns to get your money quickly. One hitch: You must subtract $500 from the loss before writing it off.

Potential savings: $6,860 if you took a $25,000 hit

8. You made energy-efficient home improvements

For 2009 the government offered taxpayers more green for going green. You can take a credit worth 30% of what you spent on energy-saving skylights, replacement windows, water heaters, and the like. (Go to energystar.gov to see what qualifies.) But instead of the $500 cap previously on this benefit, you can now claim a combined $1,500 for 2009 and 2010.

If you went green in a big way — installing a solar, wind, or geothermal energy system into your house, for example — you can cash in on a 30% credit, with no upper limit. (Previously this maxed out at $2,000.) If this latter credit exceeds your total tax bill, you can apply the unused portion to next year’s return, says Luscombe.

Potential savings: $1,500 if you spent $5,000 on windows and skylights

Potential savings: $10,500 if you spent $35,000 on solar heat and electric

9. You own property but don’t itemize

Those who itemize their deductions typically get credit for their property taxes. But those who didn’t itemize missed out on this break in the past. For the 2009 tax year (as in 2008), joint filers who don’t itemize are allowed to deduct as much as $1,000 of those taxes. This is especially valuable to anyone who’s paid off a mortgage, or come close, and doesn’t have enough mortgage interest to justify itemizing. Use the new Schedule L to nail down this deduction.

Potential savings: $280 for $1,000 in taxes

10. You picked up a second job

Many Americans took freelance work in 2009 to make up for smaller paychecks and shrunken investment accounts. Whether you spent time selling old baseball cards on eBay or consulting for a former boss, you probably have a business by IRS standards. And that gives you a whole host of write-offs, including costs of supplies, equipment, and work-related errands (55¢ a mile for business use of your car).

Better yet, if you’re running this side operation out of a home office — and not also using it as a TV room/guest room/playroom — you can deduct a prorated share of your utility bills and even your mortgage payments.

Potential savings: $420 on the typical home office alone

11. You moved for work

Did the miserable job market send you searching far and wide for employment? If you ended up relocating for a full-time position that’s at least 50 miles farther from your old home than your last job was, you can deduct your moving expenses on Form 3903. That includes the cost of the moving company or truck rental, boxes and tape, shipping your car or your pet, storing your things, starting and stopping utilities, and traveling to the new location.

Potential savings: $1,540 if the move cost $5,500

12. You’re a high earner

Top earners usually pay for their fat paychecks in reduced exemptions and deductions. But if you’re among those bringing home big bacon, you’ll be glad to hear that, for you, the 2009 tax code is kinder and gentler. Two ways you’ll benefit:

You’ll get credit for your kids: This year anyone who doesn’t fall into the AMT zone will get some personal exemption for claiming their children as dependents. In previous years that exemption — $3,650 for 2009 — phased out at higher income levels. This year it phases down to $2,433, but not out.

Potential savings: $852 per kid, assuming you’re in the 35% tax bracket

You get more from itemizing: Typically, high-income-tax filers have to reduce their itemized deductions by 3% of the amount their AGI exceeds a certain threshold ($166,800 for single and joint filers in 2009). But for 2009 that reduction comes down to 1%.

Potential savings: $142 for the average itemizer in the 28% bracket.

Medical marijuana users risk job loss

Medical marijuana users risk job loss

By Stephanie Chen, CNN

maijuana 1 Medical marijuana users risk job loss

(CNN) — When a rare form of cancer invaded Joseph Casias’ nasal cavity and his brain, his doctor prescribed marijuana to help alleviate the daily pain.

Casias lives in Michigan, where medical marijuana is legal.

But his employer, Wal-Mart, the nation’s largest retailer, fired him in November 2009 after he failed a drug test.

Casias, 29, says he never came to work high. He’s got a medical marijuana card to prove he’s allowed to smoke legally in the state.

“I was angry they did this to me because I always tried my best,” said Casias, who was employed at Wal-Mart for five years. He earned an Associate of the Year award in 2008. “I want my job back. I thought I was part of the Wal-Mart family.”

To date, 14 states have laws allowing the use of medical marijuana, which shield legal users from criminalization but don’t protect them from them penalties enforced by their employers. As more people are being prescribed marijuana across the nation, they are wrestling with a caveat: They could be fired.

Health.com: Medicinal marijuana by state

Without laws defending medical marijuana users from employers’ drug policies, Casias and a growing number of medical marijuana users are being let go from their jobs, says Keith Stroup on the legal counsel team of the National Organization for the Reform of Marijuana Laws. He said his office, headquartered in Washington, receives about 300 e-mails and phone calls a year from medical marijuana users who have been fired or had job offers rescinded because of a failed drug test.

“Usually they talk about how they have lost their job,” Stroup said. “And I tell them there’s not a thing they can do about it.”

There is no national estimate of how many medical marijuana users are at risk of being fired — or of not being hired — for using the drug as part of their treatment. Many employees, who have been fired for using doctor-prescribed pot, often remain quiet because they fear the stigma or threat losing their next job opportunity.

In California, the first state to legalize medical marijuana, 37,000 medical marijuana cards have been authorized since 2004. In Michigan, where Casias lives, the Department of Community Health reports about 10,800 people have medical marijuana cards.

Michigan is an at-will employment state, which means employers can terminate a worker for any reason except for being in a federally protected class such as race, gender and religion.

But medical marijuana users are not considered a protected group. If a company has zero-tolerance drug policies, then they can fire someone who uses medical marijuana, attorneys say. Labor law experts say most states operate this way, unless the employee has a specific employment contract that makes exceptions for medical marijuana use.

In 2008, the California Supreme Court backed up employers, ruling a private company could fire an Air Force veteran whose doctor prescribed him marijuana for his chronic and disabling back pain. The veteran was hired by a telecommunications company but fired several weeks after he tested positive for marijuana. The landmark case has many medical marijuana users fretting about their employment prospects, legal experts say.

But Michigan may be an exception to most states. Part of Michigan’s law, passed in 2008, does address employers, saying a patient carrying a medical marijuana card cannot be “denied any right or privilege” by a “business or occupational or professional licensing board.”

Some attorneys say Michigan’s law could be fertile grounds for a discrimination suit. Casias hasn’t decided whether he will pursue a lawsuit.

Some attorneys say Wal-Mart acted within legal bounds in Casias’ termination. Although some states have legalized medical marijuana, the federal government still bans the drug. Many employers like Wal-Mart argue they are following federal guidelines.

“It’s just an unfortunate situation all around,” said Greg Rossiter, a Wal-Mart spokesman. “We are sympathetic to Mr. Casias condition, but like other companies we have to consider overall safety of our customers and associates, including Mr. Cassias, when making a difficult decision like this.”

James Shore, a labor attorney in Washington who represents employers, says companies are afraid medical marijuana users may perform their job while impaired.

“The key thing for employers is to make sure they review their drug testing and human resources policies from top to bottom,” Shore said. “They need to make a companywide decision and be consistent about it.”

Dr. Lester Grinspoon, a professor emeritus at Harvard Medical School, explained the impairment issue: The high from marijuana usually disappears after a few hours. For patients, who medicate with marijuana frequently, they build a higher tolerance against impairment.

Casias said he never smoked right before his shifts. He had been using medical marijuana for about four months before he failed the drug test.

The debate on whether employers can fire medical marijuana users comes at a time when more states are expected to legalize medical marijuana. At least 16 states are considering the legalizing medical marijuana during this legislative session, according to the National Conference of State Legislatures. Even states once considered to be conservative on drug policies, such as Kansas and Alabama, are reconsidering.

The push toward legalizing medical marijuana is gaining clout.

Last fall, the American Medical Association asked the federal government to review the classification of marijuana and move the drug into a less restrictive category. The AMA has not taken a position on supporting states that have legalized medical marijuana. A state lawmaker in Colorado this week wants to draft a law that would allow veterans suffering from post-traumatic stress disorder to access medical marijuana with a doctor’s permission.

Jonathan Hogue, 27, believes the workplace should allow for legalized medical marijuana use. The Portland, Oregon, resident suffers from arthritis and relies on marijuana to ease his back pain. A physician wrote a prescription for him, he says, but a few months ago a nursing job offer was rescinded because of his medical marijuana use. CNN contacted the private nursing company but did not get a response.

“It’s straight discrimination,” Hogue said. “I was trying to be completely honest with them about not trying to hide it because it’s not illegal.”

Supporters of medical marijuana also argue prescription drugs such as Oxycodone can be just as dangerous and widely abused.

“If you are a medical marijuana user, you’re treated like a drug addict or a second-class citizen,” said Douglas Hiatt, a labor attorney in Seattle, Washington, where medical marijuana is legal. He’s encountered dozens of medical marijuana patients who have lost jobs. “What other medicine out there causes this much trouble?”

Trouble is what Joseph Casias, a father who needs to support his family, is facing after Wal-Mart let him go. He’s already accrued $10,000 of debt from unpaid medical bills. Living on unemployment checks, he constantly worries whether his cancer will get worse since he can no longer afford treatment.

This month, a group of supporters have come to his side, holding rallies and forming a Facebook group “Let Joseph Casias Talk.” Casias is thankful for all the support, but ultimately, he said, he just wants his job back.

کشف نوع ناشناخته ای از انسان کهن در سیبری

کشف نوع ناشناخته ای از انسان کهن در سیبری

siberia 226x283 nocredit کشف نوع ناشناخته ای از انسان کهن در سیبری

ل رینکون

خبرنگار علمی بی بی سی

دانشمندان یک نوع انسان کهن که تاکنون ناشناخته بود را با تحلیل دی ان اِی استخوان انگشت در غاری در سیبری شناسایی کرده اند.

این گونه منقرض شده که “هومینین” نامگذاری شده از 48 هزار تا 30 هزار سال پیش در منطقه آسیای مرکزی زندگی می کرده است.

تیمی بین المللی مواد ژنتیکی به دست آمده از فسیل این موجود را که از نئاندرتال و انسان امروزی متمایز است، سلسله بندی کرده است.

جزئیات یافته های مربوط به این موجود موسوم به “زن ایکس” در نشریه علمی “نیچر” چاپ شده است.

زیورآلاتی شامل دستبند نیز در همان لایه از خاک که استخوان انگشت در آن قرار داشت پیدا شده است.

پروفسور کریس استرینگر پژوهشگر در زمینه سرمنشا انسان در موزه تاریخ طبیعی لندن این یافته را یک “تحول خیلی هیجان انگیز” خواند.

او گفت: “این مطالعه تازه با کمک دی ان اِی یک راه کاملا جدید برای بررسی تکامل انسان در آسیای مرکزی و شرقی که هنوز درک درستی از آن وجود ندارد فراهم می کند.”

کشف جدید این احتمال جالب را مطرح می کند که سه نوع انسان – هومو سیپین، نئاندرتال و هومینین – ممکن است در جنوب سیبری با هم ملاقات کرده و تعامل داشته اند.

تکه ریز استخوان انگشت توسط باستان شناسانی که در سال 2008 در غار دنیسووا در کوه های آلتای سیبری کار می کردند کشف شد.

تیمی بین المللی از پژوهشگران دی ان اِی میتوکوندریال را از استخوان استخراج کردند و کد ژنتیکی آن را با انسان های مدرن و نئاندرتال ها مقایسه کردند.

سرمنشاء نامعلوم

دی ان اِی میتوکوندریال از نیروگاه های سلول می آید و تنها از طریق مادر منتقل می شود.

تحلیل انجام شده توسط ژوهانس کراس و همکارانش از موسسه ماکس پلانک برای تحقیقات مردم شناسی تکاملی در لایپزیگ آلمان، نشان داد که موجود کشف شده در دنیسووا آخرین بار حدود یک میلیون سال پیش جد مشترکی با انسان و نئاندرهال داشته است.

آن تاریخ به عنوان زمان واگرایی شناخته می شود؛ یعنی زمانی که اجداد این انسان از خطی که در نهایت به تکامل نئاندرتال و ما منجر شد، جدا شد.

خط تکاملی نئاندرتال و انسان امروزی خیلی دیرتر از هم جدا شد، یعنی در حدود 500 هزار سال قبل. این نشان می دهد که فردی که در دنیسووا پیدا شده نماینده یک دودمان ناشناخته انسان است که از آفریقا به آسیا مهاجرت کرده بود.

پروفسور سوانته پابو از موسسه ماکس پلانک که از نویسندگان مقاله تازه است گفت: “هرکسی که این ژن را حدود یک میلیون سال قبل از آفریقا بیرون برد موجودی تازه است که تاکنون در صفحه رادار ما دیده نشده بود.”

هومینین که نمونه آن در دنیسووا پیدا شد نمی توانسته از اعقاب هومو ارکتوس باشد که حدود دو میلیون سال قبل از آفریقا به آسیا مهاجرت کرد.

به علاوه کهنتر از آن است که از اعقاب هومو هایدلبرجنسیس، یک انسان قدیمی دیگر که تصور می شود سرمنشاء آن به 650 هزار سال قبل می رسد باشد.

دکتر کراس گفت که لایه ای از خاک که بقایای زن ایکس در آن پیدا شد حاوی ابزارهایی شبیه آنچیزی است که انسان های امروزی ده ها هزار سال قبل در اروپا می ساختند.

البته او به بی بی سی گفت به راحتی نمی توان ثابت کرد که استخوان انگشت لزوما به این زیورآلات مرتبط است زیرا امکان جابجایی استخوان در این محوطه باستانی وجود دارد.

تحقیقات تازه به ایجاد تصویری پیچیده تر از نوع بشر در دوره نهایی پلیستوسین که انسان مدرن آفریقا را ترک کرد و به شکل گروهی در نقاط دیگر زمین سکنی گزید کمک می کند.

به نظر می رسد که نئاندرتال ها نیز حدود 40 هزار سال قبل در غار اوکلادنیکوف در کوه های آلتای زندگی می کردند. و تیمی تحت سرپرستی پروفسور آناتولی درویانکو از آکادمی علوم روسیه نیز شواهدی از حضور انسان مدرن در این منطقه در تقریبا همان زمان پیدا کرد.

اما دانشمندان می گویند که پاسخ این معما را که آیا این موجودات با یکدیگر تعامل یا آمیزش داشته اند یا خیر را نمی دانند، اما به احتمال قوی تر آمیزشی میان آنها صورت نگرفته است.

Facebook plans to add ‘place’ feature

Posted on 26 March 2010 by admin

Facebook plans to add ‘place’ feature

By John D. Sutter, CNN

facebook.settings.courtesy Facebook plans to add place feature

(CNN) — Facebook on Friday proposed creating a way for people to add their locations to Facebook pages but released almost no details about how the feature will work.

The location-based feature, hinted at in a post on Facebook’s blog, would give the social network’s 400 million-plus members a function that has been popularized on newer “location-based” Web sites likeFoursquare and Gowalla.

Those two sites feature mobile apps that are set up like games, encouraging smartphone- or laptop-wielding users to “check in” at restaurants, businesses and public locations. When a person checks in to a certain spot, his or her friends are alerted about their whereabouts.

Posting locations in addition to status messages and Web links has become a major theme of online social networking this year.

In a blog post on Friday, Michael Richter, Facebook’s deputy general counsel, provided few details about how the places feature would work but did confirm that Facebook is working on featuresthat use people’s locations.

He writes that the addition is “more exciting” than a location feature the company had been planning.

“The last time we updated the Privacy Policy, we included language describing a location feature we might build in the future. At that point, we thought the primary use would be to ‘add a location to something you post.’ Now, we’ve got some different ideas that we think are even more exciting,” Richter wrote.

“So, we’ve removed the old language and, instead added the concept of a ‘place’ that could refer to a Page, such as one for a local restaurant. As we finalize the product, we look forward to providing more details, including new privacy controls,” the post says.

This month, The New York Times cited unnamed sources saying Facebook would unveil its location-based feature at its annual f8 conference for Facebook application developers, which begins April 21 in San Francisco, California.

Friday’s Facebook post also says that the massive social networking site will make changes “sometime soon” to the policies that govern how it works.

Such alterations typically draw raucous debate, and often backlash, from the Facebook community, but the site says it is announcing the changes for review before they go into effect so users will have time to read them and post comments.

The idea of a “place” is mentioned at least twice in the proposed policy.

“Once you register you can provide other information about yourself by connecting with, for example, your current city, hometown, family, relationships, networks, activities, interests, and places,” the policy says.

In a section about information the site collects about you from other users, the policy says: “We may collect information about you from other Facebook users, such as when a friend tags you in a photo, video, or place, provides friend details, or indicates a relationship with you.”

The addition of “place” into Facebook lingo is an important change, Marshall Kirkpatrick writes on the blog ReadWriteWeb.

“The difference between location and Place is a significant one. Substantial resources are dedicated by location-aware social networks to determine what ‘place’ your location refers to,” he writes.

“That might mean neighborhood, it might mean business name and it might mean recognizing when you are posting from home so that location can be selectively hidden if you so choose.”

On the tech blog VentureBeat, Kim-Mai Cutler writes that the “place” feature could make Facebook pages for businesses and television shows more interesting.

“This could make Fan Pages for restaurants a lot richer and maybe even competitive to Google’s Place Pages or Yelp’s listings,” she writes.

“If you could tag an update or post with a venue, you probably attach comments, mini-reviews and photos to the Fan Page.”

Health care bill anger a sign of the times?

Health care bill anger a sign of the times?

By Ed Hornick, CNN

angryprotester.gi Health care bill anger a sign of the times?

Washington (CNN) — Americans have always exercised their Democratic rights under the U.S. Constitution to speak out against the government.

Amid the bitter fight over health care reform, a round of hate-filled messages and sometimes violent actions toward members of Congress has prompted calls to ease up on the rhetoric.

Experts say that although protests against social issues such as health care reform are nothing new for the country, such reaction to a landmark bill’s passing is uncommon.

“It’s unusual that you get this kind of outrage and response to a piece of legislation,” said historian Robert Dallek, author of the upcoming book “The Lost Peace: Leadership in a Time of Horror and Hope.”

“Of course, it’s being fanned in some ways by Republican leaders who keep saying majorities are against this legislation, when in fact there is a pretty even divide in the country, from what the polling data shows,” he added.

And those polls indicate that while the country was somewhat evenly divided on the issue in the months leading up to the vote, there has been a bounce in favor of President Obama and the bill.

Throughout last summer and fall, health care reform protesters took to Washington and town hall meetings across the country. Signs at some protests, depicting Obama as Nazi leader Adolf Hitler or calling him a “witch doctor,” created a heightened sense that the movement against health care reform had taken an ugly turn.

The recent “sleazy” behavior is highly alarming, CNN Senior Political Analyst David Gergen said.

“It is sleazy. But this whole thing has gotten to a level of nastiness that I don’t think we’ve seen in some years,” he said. “Just as the partisanship has become so hyper now, the rhetoric is so hyper.”

Michael Murakami, a professor of political science at Georgetown University, said it’s certainly not the first time the country has seen this kind of activity, “inspired by political events that touch a nerve.”

“But it’s seems like it’s been the first time in recent memory that we’ve seen landmark legislation and also a kind of mass emotional response you get from these controversial but very landmark bills,” Murakami said.

History has shown that controversial issues dealing with social or fiscal policies can be the sparks that ignite a flame in people. Here are some other notable events:

Crime bill

CNN Senior Political Analyst Gloria Borger said that a lot of the violence and threats now being reported are reminiscent of past legislation involving social issues, especially the crime bill signed by President Clinton.

The Violent Crime Control and Law Enforcement Act, the largest crime enforcement legislation in U.S. history, became law in 1994. It provided funding for hundreds of thousands of police officers, gave aid to crime-prevention programs and put restrictions on weapons, including firearms.

“After the crime bill passed, people [who felt there was strict] gun control in it … felt the role of government was too huge. After that, you had Oklahoma City [federal building bombing],” Borger said.

A bomb ripped through the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma, in 1995, killing 168 people.

Timothy McVeigh, an Army veteran, was convicted of planning the attack and setting off the bomb. He was executed in June 2001. Others, including Terry Nichols and Michael Fortier, are serving time for assisting in the crime and not warning about the attack, respectively.

A lot of the same anti-government anger was seen a couple of years before the bombing, namely in the shootout in April 1993 that started the siege of the Branch Davidian compound near Waco, Texas, by Alcohol, Tobacco and Firearms agents.

The government believed that the religious group, headed by David Koresh, had stockpiled weapons. A 51-day standoff ended when the FBI stormed the compound, and a group of buildings caught fire and burned to the ground, killing 80 people inside. Four ATF agents were killed.

Civil Rights Act

Going back even further, the Civil Rights Act of 1964 was controversial among many in the South. And although violence against blacks continued after the bill’s passage, there was no discernable peak in reaction.

“After Lyndon Johnson passed the civil rights bill in 1964, he was apprehensive that there was going to be a violent protest against it in the South,” Dallek said. “This proved to be wrong.”

Dallek said Johnson assumed that if the change in racial relations was done through Congress instead of the courts, “it would be very difficult for Southerners … to express opposition in a violent way. That proved to be right.”

Economic depression

But Dallek said that a lot of the anger behind the health care protest isn’t just about the issue but rather people channeling frustration with the economic climate.

“I think it’s partly the fact that you have this recession, an economic problem that puts people further on edge than they are normally,” he said. “I think there’s an awful lot of anxiety about that out there. That fans the flames of agitation.”

He likens those worries to fears in the 1930s with the Great Depression.

“Remember in the 1930s when you had such a dreadful economic downturn,” he said, noting that a movement popped up that was “full of a kind of rhetoric and anti-Semitism and anti-government.”

“It was an explosion of populist protests, one might say, that seems not entirely divorced from the kind of thing we’re seeing now,” he added.

The New Deal

Julian Zelizer, a presidential historian and CNN.com contributor, wrote that frustration with joblessness — like the opposition to Obama’s economic stimulus bill — was also seen during the New Deal era.

“It is possible that continued frustration about jobs allows Democrats to target Republicans as an obstructionist party that has in fact hampered their efforts to revitalize economic growth,” Zelizer wrote in the commentary. “During the 1930s, President Franklin Roosevelt understood that you could not have recovery without jobs. This is why he made public works programs the centerpiece of the New Deal.”

The New Deal, which was passed by Congress under Roosevelt’s presidency, was signed into law in 1933. The legislation included economic stimulus programs aimed at jump-starting the depression economy. Much like Obama’s effort, the New Deal relied on providing relief for those suffering, helping in the recovery of the country’s economy and urging reform of the financial system.

The New Deal, Dallek said, provoked the creation of the Liberty League, an organization “fiercely opposed to Roosevelt’s New Deal as something that was going to destroy freedom in the country and destroy the Constitution.”

Although they didn’t revert to violence, there were “a lot of verbal explosions of what Roosevelt’s New Deal was doing in the name of small government and reducing centralized authority in the country.”

We Don’t Cause VD, Claims Facebook

The social-networking giant wants to set the record straight: “Facebook is no more responsible for STD transmission than newspapers are responsible for bad vision.”

Facebook Log In monster 397x224 We Dont Cause VD, Claims Facebook

The social-networking giant wants to set the record straight: “Facebook is no more responsible for STD transmission than newspapers are responsible for bad vision.”

Cases of syphilis have increased four-fold in Britain thanks toFacebook, argued a U.K. professor, as users meet up for unprotected sex. When representatives for the massive social-network site read the assertions by Professor Peter Kelly, director of Public Health for U.K. agency NHS Tees, they were outraged, quickly issuing a terse statement denying the connection.

“The assertion that Facebook is responsible for the transmission of STDs is ridiculous,” read teh statement by the social network. “Facebook is no more responsible for STD transmission than newspapers are responsible for bad vision.”

In a further expansion to news site Techcrunch, spokesman Andrew Noyes wrote that “while it makes for interesting headlines, the assertions made in newspaper reports that Facebook is responsible for the transmission of STDs are ridiculous, exaggerate the comments made by the professor, and ignore the difference between correlation and causation.”

Noyes noted, “As Facebook’s more than 400 million users know, our Web site is not a place to meet people for casual sex — it’s a place for friends, family and coworkers to connect and share.”

Kelly had released a statement that “there has been a four-fold increase in the number of syphilis cases detected, with more young women being affected.” He argued that his staff had found a link to social networking sites among those infected.

Prof Kelly said, “I don’t get the names of people affected, just figures. And I saw that several of the people had met sexual partners through these sites.” He continued, “Social networking sites are making it easier for people to meet up for casual sex. There is a rise in syphilis because people are having more sexual partners than 20 years ago and often do not use condoms.”

Iceland fears 2nd, even larger volcanic eruption

Iceland fears 2nd, even larger volcanic eruption

REYKJAVIK, Iceland – A volcano in southern Iceland has erupted for the first time in almost 200 years, raising concerns that it could trigger a larger and potentially more dangerous eruption at a volatile volcano nearby.

The eruption at the Eyjafjallajokull (AYA-feeyapla-yurkul) volcano, located near a glacier of the same name, shot ash and molten lava into the air but scientists called it mostly peaceful. It occurred just before midnight Saturday (2000 EDT, 8 p.m. EDT) at a fissure on a slope — rather than at the volcano’s summit — so scientists said there was no imminent danger that the glacier would melt and flood the area.

TV footage showed lava flowing along the fissure, and many flights were canceled due to the threat of airborne volcanic ash. After anaerial survey Sunday, scientists concluded the eruption struck near the glacier in an area that had no ice.

“This is the best possible place for an eruption,” said Tumi Gudmundsson, a geologist at the University of Iceland.

Nonetheless, officials sent phone messages to 450 people between the farming village of Hvolsvollur and the fishing village of Vik, some 100 miles (160 kilometers) southeast of the capital, Reykjavik, urging them to evacuate immediately.

A state of emergency was declared although there were no immediate reports of injuries or damage. Evacuation centers were set up near the town of Hella, but many people returned to their homes later Sunday. The most immediate threat was to livestock because of the caustic gases the eruption released.

“We had to leave all our animals behind,” Eli Ragnarsdottir, a 47-year-old farmer, told RUV, Iceland’s national broadcaster from an evacuation center. “We got a call and a text message … and we just went.”

Scientists say it is difficult to predict what comes next. Like earthquakes, it is hard to predict the exact timing of volcanic eruptions.

“It could stop tomorrow, it could last for weeks or months. We cannot say at this stage,” Gudmundsson said.

The last time there was an eruption near the 100-square-mile (160 square-kilometer) Eyjafjallajokull glacier was in 1821, and that was a “lazy” eruption — it lasted slowly and continuously for two years.

The latest eruption came after thousands of small earthquakes rocked the area in the past month. Scientists in Iceland have been monitoring the volcano using seismometers and global positioning instruments, but Gudmundsson noted that the beginning of Saturday’s eruption was so indistinct that it initially went undetected by the instruments.

“The volcano has been inflating since the beginning of the year, both rising and swelling,” said Pall Einarsson, a geophysicist at the University of Iceland’s Institute of Earth Science. “Even though we were seeing increased seismic activity, it could have been months or years before we saw an eruption like this … we couldn’t say that there was an imminent risk for the area.”

Einarsson and Gudmundsson said the eruption could trigger a more damaging eruption at the nearby Karla volcano, which lies under the thick Myrdalsjokull icecap and threatens massive flooding and explosive blasts if it erupts.

“One of the possible scenarios we’re looking at is that this small eruption could bring about something bigger. This said, we can’t speculate on when that could happen,” Einarsson told The Associated Press.

Iceland, a nation of 320,000 people, sits on a large volcanic hot spot in the Atlantic’s mid-oceanic ridge. Volcanic eruptions, common throughout Iceland’s history, are often triggered by seismic activity when the Earth’s plates move and when magma from deep underground pushes it’s way to the surface.

All domestic flights in Iceland were canceled because airborne ash might interfere with aircraft engines, although Reykjavik appeared to be unaffected with clear visibility.

Aviation authorities were to determine whether it is safe to fly again early Monday.

A flight to Oslo was canceled, but most international flights into and out of Iceland were delayed but returning to normal, Icelandair said. The airline’s flights from the U.S. — departing from Seattle, Boston and Orlando, Florida — were due later Sunday in Reykjavik. Earlier, a flight was turned back to Boston, leaving about 500 people waiting for hours.

First settled by Vikings in the 9th century, Iceland is known as the land of fire and ice because of its volcanos and glaciers. During the Middle Ages, Icelanders called the Hekla volcano, the country’s most active, the “Gateway to Hell,” believing that souls were dragged below.

In the mid-1780s, the Laki volcano erupted, causing scores to die of famine when livestock and crops were destroyed and changing weather patterns across Europe.
