8:25 PM | Doppler Radar Sees Debris from Antares Explosion
The NWS Doppler radar at Wakefield,Va detected the debris from the Antares explosion Tuesday evening. Not only that, but it was able to show that this was not rain but debris in the air. Being a dual polarimetric radar it can detect the shape of the particles in the radar beam, and a product called the correlation coefficient showed that the echo was made up of particles that were of …

8:18 PM | The science of charismatic voices
When a right-wing Italian politician named Umberto Bossi suffered a severe stroke in 2004, his speech became permanently impaired. Strangely, this change impacted Bossi's perception among his party's followers -- from appearing authoritarian to benevolent. Subject:  Brain & Behavior

8:07 PM | Sleep apnea may affect memory of everyday events
Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research led by NYU Langone Medical Center sleep specialists suggests. The study, published online Oct. 29 in Journal of Neuroscience, demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory in humans even when other sleep stages are intact.

7:54 PM | Mercury Program: Want To Own The Camera Used By Schirra And Cooper In Space? It's Up For Auction
The camera and lens that Wally Schirra and Gordo Cooper carried into space during their Mercury Program flights is going up for auction in a few weeks. Wally Schirra, a known camera enthusiast, said the Hasselblad camera they used was held in highest regard by photographers for its superior engineering, craftsmanship, and top-of-the-line quality. He reportedly purchased the Hasselblad 500c camera at a Houston photo supply shop in 1962, and brought it back to NASA for mission use […]

6:49 PM | The Organic Smog And Ozone Created By Cleaning Your House
An organic compound called limonene provides the pleasant smell of cleaning products and air fresheners but some byproducts of these sweet-smelling compounds could be adding to the air while they remove germs and odors. By cleaning your house, you could be adding smog and ozone to it. read more

6:34 PM | Supersonic Laser-Propelled Aircraft Get A Step Closer
Aircraft propelled by beams of light rather than fuel? Laser-propulsion just got a step closer thanks to a new method for improving the thrust systems developed by physicists Yuri Rezunkov of the Institute of Optoelectronic Instrument Engineering and Alexander Schmidt of the Ioffe Physical Technical Institute in Saint Petersburg.  Currently, the maximum speed of a spacecraft is limited by the amount of solid or liquid fuel that it can carry. Achieving higher speeds means that more fuel […]

YouTube science experimenter Grant Thompson (aka: “The King of Random”) recently released an awesome new video that shows you how to make a rocket that is both powerful and cheap. How cheap? About $0.50, according to Grant. That’s because the rocket’s main ingredients, sugar and kitty litter, are both dirt cheap! Check it out in the video below: It’s definitely important to remember to check with your local authorities before setting off any […]

5:53 PM | Homo Floresiensis: Hobbit Species Continues To Provoke Questions About Human Evolution
By Sarah King, Genetic Literacy ProjectSince the discovery in 2004 of Homo floresiensis, an ancient hominid nicknamed “Flo” and also “hobbit”, after the diminutive villagers from J.R.R. Tolkien’s Lord of the Rings trilogy, due to her small size relative to modern humans, much debate has been raised over the origins of the species. read more

5:36 PM | Talking While Female: 6 Things About The Perception Of Women's Voices
You may not have realized it, but women's voices are a big topic. For women, at least. I suppose it may be true. If someone asks me to describe the characters in television comedy "The Big Bang Theory", my natural response would be 'the guy that matches the stereotype of how people think physicists are, the actual physicist, the engineer, the psychologist, the girl who looked a lot better with longer hair and the girl with the squeaky voice.'See? 16% of my responses were related to female […]

The story of how Margaret Keane became one of the most successful artists in America that nobody had ever heard of is both fascinating and terribly sad.

4:58 PM | This Mid-Term Election Can Have Evolutionary Consequences
How can the international community know it is election time in the United States? A whole raft of claims about science and why you should vote one way or the other will be produced. Some people have even claimed politics is hard-wired, which would mean that American Republicans and Democrats are distinct species, having branched off from the rest of the world in 1860.While biologists laugh at the idea that voting preferences are biological, sociologists, psychologists and political scientists […]

Titled “Implications of LHCb Measurements and Their Future Prospects,” the workshop enabled him and other members of the Large […]

4:34 PM | In The UK NHS, Interest In Being A General Practicioner Has Dwindled
The United Kingdom's National Health Service (NHS) is very popular with people who have no serious issues, because it is free - if they have to wait a few weeks, it is no big deal. For doctors, it isn't so great. The cost to attend medical school is not high, around $15,000 per year, but in their first year they will only earn about $30,000 annually. A specialist is almost 50% higher and that is part of the reason why the UK is losing General Practioners, at the bottom of the wage scale, faster […]

4:16 PM | Not All Science Is Created Equal: The Story Of Genetically Engineered Crops
By Robert Wager, Genetic Literacy ProjectThere is tremendous controversy about genetically modified (GM) crops and derived food. Even the definition of what is a GM crop can differ depending upon with whom you talk. From a strictly scientific perspective all food has been manipulated at the genetic level by human activity; therefore all foods are genetically modified.A more scientifically precise term for what goes by the popular term GMOs is genetically engineered (GE). This definition […]

4:06 PM | How An Abandoned Walmart Became America’s Biggest 1-Floor Library
It’s no secret that Walmart stores are big. Really big. The average Walmart takes up about as much space as two-and-a-half football fields. According to international supply chain consultant MWPVL, Walmart stores covered a whopping 721 million square feet of retail space in the United States in 2013. That’s an area almost 10% larger than the entire city of Manhattan (661 million sq. feet). And when a Walmart location closes, it often remains vacant for long […]

Plants rely on sunlight to make their food, but they also need protection from its harmful rays, just like humans do.
