You Won't Believe Your Ears When You Hear This: VIDEO

Trust_ears_1

Don’t believe everything that you hear. It’s not just a proverb, it’s also scientifically proven as our ears  often play tricks on us with auditory illusions.

Don’t believe us? Let ASAP Science demonstrate — you won’t believe your ears!

The geniuses at ASAP Science have also helped unravel the mysteries behind farts, stress, pain, yawning, cats, the ocean, the periodic table, staying indoors, productivity, winter illnesses, dancing, pornography, the snooze button, booze, orgasms, and other mind-blowing facts.

The iconic voice of Higher Power…now even higher.

The clip is part of the Science Channel’s “Through the Wormhole” – a docu-series narrated by Freeman that asks all the big philosophical, scientific, and cosmic questions you could possibly imagine. Like "does 'time' really exist?" "can we resurrect the dead?" and "will sex become extinct?"

CDC Releases New Guidelines For PrEP

TruvadaThe Centers for Disease Control and Prevention have issued a new set of guidelines for the use of PrEP as an HIV preventative after having determined that PrEP is an effective method of HIV prevention. Said Jonathan Mermin, M.D., M.P.H., director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention,

While a vaccine or cure may one day end the HIV epidemic, PrEP is a powerful tool that has the potential to alter the course of the U.S. HIV epidemic today. These guidelines represent an important step toward fully realizing the promise of PrEP. We should add to this momentum, working to ensure that PrEP is used by the right people, in the right way, in the right circumstances.

The guidelines acknowledge that PrEP is an additional strategy to be used for HIV prevention, and while over 90% effective at reducing HIV transmission on its own, it is most effective when used in combination with condoms and other risk-reduction practices.


10th Grade Canadian Student Discovers Better Test For HIV

Nicole Ticea

Nicole Ticea of Vancouver took part of a collaboration program with Simon Fraser University, and while there developed a new test for HIV using Isothermic Nucleic Acid Amplification. A drop of blood is placed on a microchip, which then scans for a specific protein in the viral envelope. The result is a near-instantaneous result from a test that actually scans for the presence of the virus itself, not just antibodies created by the immune system. The best part is that the technology required for this test is already in use and would simply require modifications to scan for HIV. The test still needs to undergo more stringent review to ensure its effectiveness, but a rapid test that would get infected patients analyze and on treatment quicker than ever may be right around the corner.


MIT Researchers Create Computer Model Of The History Of The Universe: VIDEO

Model of the Universe

Revealing that they might in fact be part Time Lord, researchers at MIT have constructed an immense computer simulation of the 14 billion year history of the universe, from 12 million years after the Big Bang to the present, using both the stars and galaxies we can see and the energies and dark matter that we can't.

For those of us that were never very good at astronomy, The Guardian has a great breakdown of the research and methods behind the model's construction, while Nature has the study available for purchase as a PDF and a short video of the model in action, which you can watch AFTER THE JUMP...

Study Shows Gay And Bi People Respond Positively To Same-Sex Pheromones

Chinese researchers at the Chinese Academy of Sciences recently conducted a study that showed that the brains of gay and bisexual men respond positively to androstadienone, the male pheromone found in male semen and sweat. It also showed that lesbian and bi women respond somewhat similarly to the female pheromone estratetraenol.

PheromonesUsing four separate groups of 24 gay/bi men, straight men, gay/bi women and straight women, participants were shown videos of ambiguous human figures walking forward and then asked to guess whether the human was male or female. They watched these videos while concurrently being exposed to androstadienone or estratetraenol masked with the scent of cloves.

Researchers found:

When exposed to androstadienone, heterosexual women were more likely to suggest that the wire figure was a man—but the pheromone had no effect on heterosexual men (that is, hetero men largely could not detect a male or female presence when presented with the pheromone) Perhaps most importantly, homosexual men also responded to that pheromone, suggesting that gay men innately perceive (and are perhaps affected by) male pheromones.

Straight men, meanwhile, were more likely to perceive the figure as feminine when exposed to estratetraenol. Straight women showed no effect, while lesbian and bisexual women showed a response somewhere in between…

The study’s abstract concludes:

The results provide the first direct evidence that the two human steroids communicate opposite gender information that is differentially effective to the two sex groups based on their sexual orientation. Moreover, they demonstrate that human visual gender perception draws on subconscious chemosensory biological cues, an effect that has been hitherto unsuspected.

Vice.com’s Motherboard notes, “The study is similar in its findings—if not its methods—to one published in Proceedings of the National Academy of Sciences in 2005 that found that the brains of gay men respond in a similar way to straight women when exposed to androstadienone.

The study did not include transgender men or women nor any genderqueer individuals.
