Researcher debunks “unidentified” life found in Lake Vostok

The scientists at the St. Petersburg Nuclear Physics Institute were excited when they found what they believed to be “unidentified” life near the South Pole. They collected 7 samples from Lake Vostok after drilling 3.5 kilometers to reach the lake. Scientist Sergei Bulat, who was the leader of the group that discovered the “new” species, stated, “After excluding all known contaminants… we discovered bacterial DNA that does not match any known species listed in global data banks. We call it unidentified and ‘unclassified’ life.”

But things have taken a turn for the worse. Vladimir Korolyov, head of the genetics lab at the St. Petersburg Institute, made a statement that debunks the team’s discovery. He said,

“We found certain specimen, although not many, but all of them belonged to contaminants (microorganisms from the bore-hole kerosene, human bodies, or the lab). There was one strain of bacteria which we did not find in drilling liquid, but the bacteria could in principal use kerosene as an energy source.”

The findings contradicts Bulat’s statement that they “excluded all known contaminants,” however nothing is set in stone just yet. The institute will be deploying deep-water devices to Lake Vostok within a year in order to obtain pure water samples. Korolyov stated, “For now we’d rather not say something we will be unable to whitewash even with the crystal clear Vostok water.”

This certainly puts a damper on things. The scientists had been working on this project for nearly 23 years, and all of the samples they have taken have yielded no positive results. The current samples from Lake Vostok are being analyzed by the Arctic and Antarctic Institute, the St. Petersburg Nuclear Physics Institute, and the Limnology Institute of the Russian Academy of Sciences in Irkutsk. The Moscow Microbiology Institute may analyze the samples in the future. The lake has been isolated for over 17 million years, so many of us are rooting for the scientists to discover something groundbreaking.

A mouse click burns 1.42 calories, according to researchers

Sitting at your desk all day surfing the internet with a pile of unfinished TPS reports sitting in front of you probably isn’t a good sign, and even worse, you’re probably not doing yourself a favor and getting enough exercise, or aren’t you? According to a recent study, one mouse click burns approximately 1.42 calories.

apple-magic-mouse

An article title “Convert Anything to Calories,” which was published recently in PHP Science World, calculated the number of calories burned when clicking a mouse, and it’s said that the number is 1.42 calories burned per mouse click. The authors ended up calculating the “total volume of the muscles used to bend the index finger,” which is “10.8 cubic centimeters with a total weight of 11.7 grams.”

The authors note, however, that the calories burned per mouse click may vary, since the calculation used “assumes the muscle contracted completely, so the actual amount of calories used is a little less.” Either way, you can easily burn off that Burger King Whopper with just 450,000 mouse clicks, or a Big Mac with only 387,000 mouse clicks, since a calorie is more commonly referred to as a kilocalorie, or 1,000 calories.

The average male should burn around 2,000 calories per day, with the average female burning approximately 1,700 calories per day. Obviously with a strict exercise regiment, you would be able to burn even more, and while getting exercise purely through mouse clicks probably isn’t ideal, at least you know that you’re burning calories while making your way through your Facebook News Feed.

Scientists discover unidentified life near South Pole

Scientists have discovered a new species of bacteria from water samples obtained from the ancient Lake Vostok. Lake Vostok had been isolated from the world for over 17 million years, and was protected by a thick sheet of ice. Scientists began drilling through the ice since 1989, and have been collected water samples from the lake. The scientists stated that the bacteria did not belong to the “40-plus known sub-kingdoms of bacteria.”

Scientists discover unidentified life near South Pole

Sergei Bulat, a researcher at the Laboratory of Eukaryote Genetics at the St. Petersburg Nuclear Physics Institute, stated,

“After excluding all known contaminents…we discovered bacterial DNA that does not match any known species listed in global databanks. We call it unidentified and ‘unclassified’ life.”

The bacteria’s DNA only had an 86% match to any other known organism on Earth. While 86% seems like a high figure, any figure below 90% is an indicator of a new species.

The scientists will need more samples in order to confirm their research, however they believe that no matter how much they research, they’re sure they’ve found a new species of bacteria. The scientists were able to take the water frozen on the drills at Lake Vostok to do their research, and because there was recently a new drilling session at the lake, more samples should be making their way to the scientists as we speak.

Last year, the scientists were eager to find unique species in Lake Vostok, but all of their samples showed no signs of new life forms. These new results provided them with the much needed boost and reassurance they needed to prove that their efforts were not in vain. It took the researchers 23 years to finish drilling through the 3.5 kilometer thick sheet of ice protecting the lake and the discovery of the new species of bacteria was worth it. Bulat stated,

“If it were found on Mars, people would call it Martian DNA. But this is DNA from Earth.”

Global temps highest in 4,000 years, according to report

Global warming: it’s a heated debate, but a recent report suggests that temperatures here on Earth have been the highest they’ve ever been in 4,000 years. Plus, it’s predicted that over the next few decades, temperatures are likely to surpass levels not seen on Earth since before the last ice age occurred.

earth

The study was led by Oregon State University paleoclimatologist Shaun Marcott, who gathered various data and formed a climate reconstruction containing the past 12,000 years, which is an era known as the Holocene, and it’s considered the modern geological era that included the rapid rise of human civilization around 8,000 years ago, which is considered to be a big factor in the rise of global warming.

However, what’s most impressive with this particular study is the fact that no other climate study has even come close to analyzing the last 12,000 years. In fact, no other study has broken the 2,000 year barrier. The report says that global temperatures rose gradually until around 6,000 years ago, when a gradual cooling phase started and lasted for about 5,000 years. However, that ended around 200 years, when temperatures began to rise and they haven’t stopped since.

While it’s difficult to know what exactly the climate was 12,000 years ago, since human civilization wasn’t really much a thing yet, scientists and researchers can use a variety of things that contain both physical and chemical signatures, such as ice cores, cave formations, and coral reefs. These give researchers a good idea at what the climate was like back then.

Megaupload shutdown increased legal movie downloads, according to study

What once was a haven for illegal downloading is now just an afterthought. After the shutdown of Megaupload last year, it seems users are starting to resort to legal downloading means, according to a study from Carnegie Mellon University. The study suggests that studios saw a boost in digital movie and music sales since the shutdown.

The 18-week study consisted of 12 countries, and revenues from digital sales and rentals for two movie studios were anywhere from 6% to 10% higher than they would have been if Megaupload hadn’t been shut down. Unsurprisingly, the countries that featured the most Megaupload users were the countries that experienced increased usage in legal downloads.

It’s interesting to note that most Megaupload users would think about just switching to a new service to illegally download copyrighted content, but with the movies and music easier to obtain legally, it seems a lot of users have decided to think twice after the Megaupload shutdown and have switched over the legal means.

Countries such as France, Spain, Mexico, and Belgium saw the most growth in legal downloads, while Canada, Australia, and Ireland saw the least impact. The study suggest that the number of users using legal means of obtaining digital content could rise if studios made their content more readily available.

Study: Facebook users sharing more personal info despite increased privacy concerns

Study Facebook users sharing more personal info despite increased privacy concerns

Carnegie Mellon University conducted a study following more than 5,000 Facebook users over six years, from 2005 and 2011, and found that changes in the social network’s privacy policies caused users to share more — not less — personal data. Lest you think this means that users suddenly trusted the site more, Carnegie Mellon says that Facebookers became more and more protective of their personal details as the social network grew in membership — and that the uptick in shared information is a result of increasingly granular privacy settings. If you recall, Facebook introduced new in-depth privacy controls in 2010, and the study found that the release of these new settings corresponded to users sharing more personal data, both within their network of friends and with strangers and third-party applications.

It’s been quite some time since the new privacy policy was introduced, but the university says the sample group didn’t reduce the amount of info shared with non-friends on the network, even as of 2011. The takeaway? Well, it’s safe to say that more privacy controls doesn’t equal more vigilance in protecting personal data, and it’s certainly not a stretch to call Facebook’s settings confusing. The researchers’ comparison of the struggle for privacy to the eternal plight of Sisyphus? That might be a touch more dramatic.

China Expected To Surpass U.S. With 246M Android, iOS Devices This Month

China Expected To Surpass U.S. With 246M Android, iOS Devices This Month

When Tim Cook made a visit to China earlier this year, he was quoted as saying the country could potentially become Apple’s largest market in the future. It looks as though Cook was right as a report published today believes China is expected to pass the U.S. for active iOS and Android smartphones and tablets, which would make the country the largest market for both devices.

The report comes from analytics firm Flurry as they’ve tracked over 2.4 billion app sessions a day across over 275,000 applications, which leads them to being able to accurately measure mobile device activity for over 90 percent of all of the world’s smartphones and tablets. In their report, Flurry says China was recorded as having 221 million active Android and iOS devices, while the U.S. had 222 million. By the end of February, Flurry is estimating China will have 246 million devices, while the U.S. has 230 million.

Study Says One in Three People Feel Worse about Themselves after Visiting Facebook

A recent study conducted by two German universities found that envy runs rampant on Facebook. Researchers from Humboldt University and from Technical University in Darmstadt, Germany conducted a study and found that one in three people felt worse about themselves after visiting the site and more dissatisfied with their lives.

20130123 154352

The study reports that people who browse the site without contributing were affected the most. According to the study, the biggest source of envy posted to Facebook was vacation photos. The study claimed that more than half of all envy incidents were triggered by vacation pictures.

The second most common cause of envy on the social networks is social interaction. Apparently, a lot of users get jealous over the amount of birthday greetings, likes, and comments their Facebook friends receive on posts and photos. Maybe what people need are Facebook friends who are uglier, poorer, and take less vacations.

If using Facebook really makes you feel bad about yourself, perhaps you should get off of your computer and do something about it.

President Barack Obama Wants To Fund Research Into The Effects Of Violent Video Games

050515 giba President Barack Obama Wants To Fund Research Into The Effects Of Violent Video GamesThe linking of violent video games to actual violence seems to be the topic these days and a few days ago, a survey has revealed that 75% of parents think that violent video games actually leads to real violence in their children. In fact it has recently been proposed that a sales tax be imposed on games deemed to be violent, perhaps in a bid to discourage sales. Now it seems that in a recent press announcement by President Barack Obama, he has revealed that he has tasked the Center for Disease Control to study the causes of violent behavior, and that Congress should look into researching the effects of violent video games on young minds. President Obama did not specifically target video games in his press announcement, but it was mentioned as part of the study nonetheless. A funding of $10 million is expected to be allocated by Congress. It should be noted that in the past, research has already been conducted on the link between violent video games and actual violence, but the researchers at that time concluded that there was no link. Perhaps with the $10 million budget, additional research can be carried out which will hopefully result in a more conclusive decision.

Smartphones overtake tablets in data usage for first time

We’ve been seeing a major push for tablets lately, but if a new study from Arieso is to be believed, then manufacturers might want to rethink their strategies. As it turns out, Arieso has found that smartphones have passed tablets in data usage for the first time in the three years the company has been doing these studies. You’d think that given the larger screens found on most tablets, users would turn to those devices more often for Internet access, but it seems that the tides are changing as far as mobile data goes.

iphone_5_galaxy_s_iii_2-580x435

As far as data downloads are concerned, Arieso found that iPhone 5 users download the most. In fact, iPhone 5 users downloaded four times as much stuff as iPhone 3G users, and 50% more than iPhone 4S users, who enjoyed being at the top of the list after last year’s study. Interestingly enough, Galaxy S III took home the top spot for mobile uploads, which suggest that Galaxy S III owners are uploading more pictures and video than those on iPhone 5.

Just as well, those opting for the Samsung Galaxy Tab 2 10.1 are downloading 20% more than those on iPad, so while Apple has the smartphone arena on lockdown for the time being, it’s facing some pretty stiff competition in the tablet space, at least from the perspective of mobile downloads. To top things off, we’re discovering from this study that a very small number of people use a very large percentage of data. Arieso says one percent of users consume 40% of total downlink data, with the top 0.1% is responsible for 20% of that. The top 10% of users account for 80% of total downlink data, so it seems that there are a number of users who don’t download very many things on their mobile devices.

Keep in mind that in years prior, tablets came out on top in Arieso’s studies, so there might be a little bit of back and forth in the years to come as users continue to adopt smartphones and tablets on a broader scale. Still, it’ll be interesting to see what Arieso’s data says next year, especially with the battle between iOS and Android seemingly becoming a closer race with this latest report. Stay tuned.
