1:00 PM | Man 3-D Prints A Concrete Castle In His Backyard
Where Dreams Come True Andrey Rudenko, Total Kustom This is a castle that a man 3-D printed from concrete, using a printer he built himself. We like how variations in the concrete's color stretch perfectly across the castle—the product of care and engineering on the part of the maker, Andrey Rudenko. As he wrote on his website: Layering cement was an extremely difficult task- it required extensive tuning of the printer on a programming level, as well as using exact quantities for the […]

10:09 PM | Found: The Part Of The Mouse Brain That Motivates Exercise
Lab Mouse Wikimedia Commons A team of researchers has found a part of the brain that controls how motivated mice are to exercise, according to a new study. The researchers created genetically modified mice that lacked neurons in the dorsal medial portion of a region of the brain called the habenula. The major difference was that the mice didn't like to run on mouse wheels, which normal mice love to do, the researchers reported in a paper they published in the Journal of Neuroscience. "They […]

Pooger Source Photo by Lance Cheung, U.S. Department of Agriculture Before 2012, outbreaks of so-called "influenza A variant" infections in the U.S. only popped up once in a while in the medical literature. The strain normally infected pigs and was rarely seen in humans. Then, in 2012, healthcare workers across the U.S. reported 309 human cases of influenza A (H3N2) variant, also known as H3N2v. Sixteen people were hospitalized, and one woman in Ohio died. Researchers think there were […]

9:00 PM | The Weird Ways Of Superfluid Helium
On the Surface This illustration shows quantum vortices on the surface of a nano-droplet of superfluid helium. In the background is a wheel-shaped superfluid helium drop. SLAC National Accelerator Laboratory With a temperature below -268 degrees Celsius, liquid helium keeps MRI machines and particle accelerators properly cooled (yay!). Take liquid helium's temperature even lower than that, however, and things start to get a little less practical -- and a lot more weird. At lower and […]

1:45 PM | Scientists Have No Idea Why U.S. Teens Are Having Fewer Babies Than Ever
Babies Nebraska Early Development Network The U.S. National Center for Health Statistics released today its latest report on American teenagers having babies. The results are both happy and strange. American teens are having babies at their lowest rate ever -- and that rate is falling fast. Yet, as Vox discovered, nobody knows why this is happening. One of the steadiest trends in American life is inexplicable. Here's the first graph in the NCHS report, showing a peak in teen births in […]

6:30 PM | New Painkiller Soothes The Nerves That Sense Hot Chile Peppers
Painful Peppers Warren Rachele (Wrachele) via Flickr, licensed under Creative Commons It's a chemical compound so new, it doesn't have a name.* In a paper, its creators call it either V116517 or Compound 37. (Like Chanel's No. 5 perfume! Except a drug.) Compound 37 is an early-stage, experimental painkiller drug... that works by incapacitating the protein that makes chiles taste spicy. The protein, TRPV1, appears in human nerves. In addition to sensing capsaicin, the spicy-pepper molecule, […]

1:00 PM | Epigenetics News Articles Put Too Much Pressure On Moms
Healthy Choices Dreamstime Maybe you've heard of King Henry VIII's tendency to blame his wives for giving birth to baby girls instead of male heirs. That the sex of a baby is somehow a mom's fault is a belief that's cropped up in a number of pre-scientific societies. It's total bull, of course. The sex of babies is random. For those conceiving in the old fashioned manner, there's no way to control the outcome. Most of us have come a long way since the days of blaming queens for […]

5:16 PM | A Machine That Sniffs Out American Cash
Dollar Bills iBid, State of Illinois You know that unique smell of money. You're not imagining it, either; it's real, produced from a combination of the paper and ink it's printed with, and it's even detectable by sniffer dogs. Now, one California company is hoping to build a portable machine that can smell out money as well as a dog can. KWJ Engineering is developing something it's calling the Bulk Currency Detection System, to detect fat stacks of laundered American cash as it's carried […]

2:30 PM | 1,024 Robots Self-Assemble Into Any Shape You Want
At Your Service Michael Rubenstein, Harvard University How does one charge 1,000 robots? It would be a pain to plug them all in individually. Luckily, there's an easier way with Kilobots. These little robots have round bodies about the diameter of a quarter, with a metal spring on top and three thin metal legs. To charge them, you push them -- 10 at a time -- against a long charging rack. They all charge at once, as long as each has its spring top and two of its legs touching the […]

5:15 PM | The Sharpest-Yet Satellite Images Of Earth To Go On Sale In Six Months
WorldView-3 Ready for Launch Ball Aerospace Finer-than-ever satellite images may soon be available to anyone in the U.S. who's willing to pay for them. This is a development that depends on both technology—the ability to see stuff that small from space—and politics—whether U.S. regulations will allow a commercial company to sell high-resolution images of the Earth. Previously, the sharpest (commercial) eye on Earth was the GeoEye-1 satellite, which has a resolution of 41 […]
