Bankers’ Bad Behavior Is Driven By Workplace Culture

It’s been six years since the 2008 financial collapse, and revelations of dirty deeds in the banking industry are still making headlines even today. By one measure financial services is the least trusted sector of the economy the world over, beating even pharmaceutical companies and — gasp! — journalists.

But the question remains, is this because banking attracts inherently dishonest people? Or is it that the culture of banking encourages otherwise fine people to act badly? A new study on bank employees finds that the latter is overwhelmingly true: bank employees tend to behave dishonestly only after they’ve been made to think about their profession.

Study of Gay Brothers Suggests Genetic Basis of Male Homosexuality

Are people born gay or is it a choice? A new study of gay brothers, the largest to date, adds more scientific evidence that there’s a genetic basis for homosexuality.

A genetic analysis of over 409 pairs of gay brothers found that two areas of the human genome, a portion of the X chromosome and a portion of chromosome 8, were associated with the men’s sexual orientation. The findings gel with a smaller study conducted in 1993 that implicated the same area of the X chromosome. Read More

In New York Bay, Humpback Whales Make a Dramatic Comeback

By Wudan Yan | November 18, 2014 9:17 am

whale watching

New York City’s urban waterways are again becoming home to some residents who haven’t been seen for hundreds of years: Humpback whales. A common presence in pre-colonial times, humpbacks vanished from New York’s waters as their numbers plummeted globally.

But there are signs of a resurgence. In the busy New York Bay, where the Hudson River meets the Atlantic Ocean, whale spotters have recorded twice as many whales this summer as last summer, and almost 20 times as many as in 2011. Researchers say that a cleaner bay and a growing population of fish for whales to feed on are responsible for the trend.

Pucker Up: One French Kiss Swaps 80 Million Bacteria

By Carl Engelking | November 17, 2014 1:51 pm

When you lock lips with that special person, you’re not only sharing your bubbling passions, but also your unique blend of oral bacteria.

In a study that’s sure to stoke the flames of love, scientists discovered that lovebirds exchange some 80 million bacteria after swapping spit for 10 seconds. That sounds like a cavity waiting to happen. But don’t worry: Scientists also found that it takes a lot of kisses to significantly change your mouth’s unique collection of microbes. Read More

Philae Rushes to Gather Data as Battery Power Dwindles

Update: 4:32 p.m. Central Time: Philae has come through! The European Space Agency on Friday confirmed that it had reestablished stable communications with the lander. Philae is beaming back more data from the surface of Comet 67P/Churyumov-Gerasimenko.

Scientists also confirmed that they commanded Philae to rotate in order to expose its solar panels to more sunlight. If they can get Philae into more sun, the lander’s batteries could be recharged and extend its mission. We’ll have more on this story as information becomes available. 

What a couple days it has been for Rosetta’s Philae lander. And although it’s been a thrill, it appears that the end is near for the little lander that could.

That’s because Philae bounced into the shadow of a cliff, and so it’s unable to generate the electricity it needs to carry out its full plan of months-long observation. Today researchers are scrambling to conduct as many experiments and gather as much data as possible before Philae’s batteries die — likely sometime in the next 14 hours. Read More

Philae Lander Is In a Precarious Position on Comet 67P

If we learned one thing yesterday, it’s that there’s no shortage of drama in space exploration.

After separating from the Rosetta spacecraft, the Philae lander descended toward the surface of Comet 67P/Churuymov-Gerasimenko to make history, but when it reached its destination Philae didn’t quite stick the landing like expected. Read More

Live Blog: Rosetta Mission Philae Lander On Its Way to Comet Touchdown

By Carl Engelking | November 12, 2014 7:58 am

After traveling over 4 billion miles, and spending more than a decade in transit, the European Space Agency’s Rosetta spacecraft’s final stage is in progress: landing a probe, called Philae, on the surface of Comet 67P. The tricky maneuver will be the first of its kind if successful — and we’ll be following its progress here live.

Wirelessly Control Mice With the Power of Your Mind

Tibetan nuns can raise their body temperature to 101 degrees Fahrenheit through their mastery of certain meditation techniques. But in the future, even a spiritual novice could use mind power to control their body’s biological functions such as pain management or the secretion of hormones.

And when we say future, we’re talking decades and not centuries.

That’s because scientists have just laid the groundwork for mind-controlled biology. Humans used their minds to control gene expression in mice that were fitted with a wireless optical implant. Yes, scientists have created a mind-controlled transgene expression device.

The Virus That Could Be Making You Dumber

You may have heard the saying, “You can’t catch stupid” — meant to console you that idiocy is not contagious. But, as it turns out, in a small way it might be.

Scientists have discovered that a foreign virus in some peoples’ throats parallels with those individuals’ poorer cognitive performance. And when mice are given this virus, previously thought to only infect algae, they were slower to learn a maze.

Bats Send Jamming Signals to Steal Rivals’ Meals

At home in the cave, bats may live in one big happy colony; but when it comes to mealtime, friends quickly become rivals.

Bats rely on echolocation — sending out calls and listening for echoes — to track down their prey. Just before nabbing their meal, bats send out a series of rapid chirps to home in on their target. But a new study reports that sometimes they’re thwarted: other hungry bats nearby can send out ultrasonic jamming signals to confound their colony-mates’ targeting system and steal the meal for themselves.
