9:12 PM | Pair bonding reinforced in the brain
In addition to their song, songbirds also have an extensive repertoire of calls. While the species-specific song must be learned as a young bird, most calls are, as in the case of all other birds, innate. Researchers at the Max Planck Institute in Seewiesen have now discovered that in zebra finches the song control system in the brain is also active during simple communication calls. This relationship between unlearned calls and an area of the brain responsible for learned […]

9:09 PM | Politics can interact with evolution to shape human destiny
Politics can have unintentional evolutionary consequences that may cause hastily issued policies to cascade into global, multigenerational problems, according to political scientists. "Most western democracies look at policies as if they are bandages, we fix what we can and then move on," said Pete Hatemi, associate professor of political science, Penn State. "But we need to consider generational policies so that we can fix what we can now, but also be prepared for what comes next." […]

8:46 PM | Halloween Buzz
It’s Halloween week (YAY) and there’s plenty to do around town. I’d personally recommend watching The Witches (I can’t believe that we were allowed to watch this in second class), followed by Hocus Pocus (while eating Banshee Bones), then heading to a gaff party dressed-up in a cumbersome cardboard costume. But if you plan on heading into town, […] The post Halloween Buzz appeared first on HeadStuff.

8:38 PM | Everyone Hates Daylight Savings Time - But It Might Improve Public Health
It's not easy to blame childhood obesity on sunsets but scholars at the London School of Hygiene and Tropical Medicine and the University of Bristol say that later daylight couldn't hurt - and they even defend daylight savings time, which most people can't find much good to say about. The scholars analyzed the lifestyles of over 23,000 children aged 5-16 years in nine countries; England, Australia, USA, Norway, Denmark, Estonia, Switzerland, Brazil and Madeira and Portugal. They looked for […]

On May 29th, 2014, the leaders of Belarus, Kazakhstan, and Russia signed a treaty establishing the Eurasian Economic Union (EEU), also known simply as the Eurasian Union. Earlier this month, on October 9th, 2014, a treaty to add Armenia to the EEU was signed. This Union will officially go into effect on January 1st, 2015. When it does, it will be the most advanced organization for regional cooperation the former Soviet bloc (ie. countries that were once part of the Soviet Union)

8:21 PM | Does Flopping Work In Basketball?
In the United States, professional basketball, the NBA, opens its regular season tonight. That means at this time tomorrow there will be talk that some player 'flopped' - fell on the ground to draw a foul and get a chance at a free basket. A new analysis has found that two-thirds of the falls examined by the group at Ben-Gurion University of the Negev were found to be intentional.  And it happens a lot. It happens so much because there is insufficient punishment for […]

8:00 PM | Groove is in the hive
Bees have long been famous for their “waggle dance”, a series of moves telling other bees where good food can be found. But do you know just how intricate this dance is? It turns out bees have a complex language and we know how to eavesdrop onto their conversations.

7:49 PM | Run Up To 25 MPH With These Bionic Boots (Video)
Since he was a teenager, Keahi Seymour has admired the incredible speeds of the Ostrich and other land-dwelling two-legged creatures. With ostriches able to reach top speeds of up to 45 mph, Seymour was determined to unlock the secret to their quickness. His solution: super boots that (literally) add a spring to your step, increasing your force and speed. According to Popular Science… “Many years and a dozen prototypes later, Seymour came to Maker Faire (Sept. 2014) to […]

7:26 PM | Reduce Prostate Cancer Risk By Sleeping With Lots Of Women - But Not Men
Men who have had sex with more than 20 women have a 28% lower risk of getting prostate cancer than those who have had only one partner  - but males having more than 20 male partners face a 100% higher risk of getting prostate cancer than those who have never slept with a man.  The results were obtained as part of the Montreal study PROtEuS (Prostate Cancer&Environment Study), in which 3,208 men responded to a questionnaire on, amongst other things, their sex lives. Of these […]

7:15 PM | Organic Movement Rejects Science, Embraces ‘Natural’ Ebola Cure
As the death toll of Ebola continues to rise, especially in the hard-hit West African countries of Liberia, Sierra Leone, and Guinea, the need for a viable cure is growing more and more urgent. Even more concerning is the possibility that once approved, vaccines may not be widely available for several months.As often happens in times of medical crises, fringe groups come out from hiding–in this instance, organic activists in the form of the most high profile organic lobby group in the […]

sci-universe: The “Hendo Hoverboard” is far from being a consumer device.But we have to start from somewhere, right? So there’s this Kickstarter campaign for the “Hendo Hoverboard”, similar to the one we all wanted after seeing Back to the Future. First of all, yes, I was freakin’ excited for this! But you gotta do research before thinking you can float around on this thing tomorrow. The magic science behind the hoverboard lies in four electromagnets on the […]

6:38 PM | The Chemistry of The Colours of Blood
Halloween’s almost here, which, for a large number of costumes, will require a liberal dousing of fake blood to complete the look. You probably already have a pretty good idea of the reasons behind the red colouration of human blood that fake blood mimics. However, red is not the only blood colour available – it also […]

5:30 PM | NPR disbanded its climate and energy team--and nobody noticed.
It seems nobody noticed until last Friday, but National Public Radio has disbanded its four-member climate and energy team. In January, Vikki Valentine, the team's editor, was reassigned to lead global health and development coverage. (NPR's media relations director, Isabel Lara, said that "includes global climate and environment stories.") In March, one of the team's reporters, Richard Harris, abruptly switched to medical coverage. In June, reporter Elizabeth Shogren was laid off. The last […]

4:32 PM | One giant leap for preservation: protecting moon landing sites
Who will preserve the first lunar landing site at Tranquility Base for future generations? It seems an odd question given the fact that this extraordinary archaeological site was created on July 21, 1969 – less than 50 years ago. Although its remoteness has protected the site for almost a half century, it is not immune to future adverse impacts – and you’d be hard pressed to find someone who didn’t think that it is a place important to humanity. So how should […]

4:22 PM | Boosting Vitamin D levels could help manage asthma attacks
Asthma, which inflames and narrows the airways, has become more common in recent years. While there is no known cure, asthma can be managed with medication and by avoiding allergens and other triggers. A new study by a Tel Aviv University researcher points to a convenient, free way to manage acute asthmatic episodes — catching some rays outside. Subject:  Health & Medicine

4:16 PM | Prehistoric Continental Shelf: Tracing Our Ancestors At The Bottom Of The Sea
The social sciences have simultaneously become increasingly specialized and over-lapping. A new field calls itself Continental Shelf Prehistoric Research and it studies the remains of prehistoric human settlements which are now submerged beneath coastal waters. Some of the now-drowned sites are tens of thousands of years old, requiring archaeologists to get help from oceanography and the geosciences. A recent paper describes how during the successive ice ages of the last million years, the […]

3:50 PM | A new dent in HIV-1's armor
Like a slumbering dragon, HIV can lay dormant in a person's cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists at the Salk Institute have uncovered a new protein that participates in active HIV replication, as detailed in the latest issue of Genes & Development. The new protein, called Ssu72, is part of a switch used to awaken HIV-1 (the most common type of HIV) from its […]

3:32 PM | Why There Are Fewer Female Economists
Economics is a dwindling field. Long called the 'dismal science' it is now considered just another philosophical school of thought; people in the money business who want quantification hire physicists rather than economists. And the lack of female interest in the field shows it is no longer in vogue. A new analysis finds that women make up 57 percent of undergraduate classes at UK universities but only 27 percent of economics students. The women who like math are doing something else with […]
