Actor and producer Renee Zellweger has a new face. So far, so Hollywood, right? But the usual blogs and clickbait sites have exploded with coverage, and inevitably other blogs have responded saying the actor's choice of plastic surgery is hers alone, and none of our business. But why are people so interested in yet another celebrity going under the knife? Could it be because of unique human brain biology?
Of sports played on ice, hockey tends to get the most attention when it comes to injuries. But figure skaters are also pretty injury-prone, and because of the aesthetic nature of their sport, most figure skaters eschew pads and protective gear while on the ice. This means avoiding injuries can be difficult for practitioners of the sport, in which skaters can exert forces of more than six times their body weight during a jump.
In Xbox One’s newest software updates, which roll out in November, the gaming console's television functions will be integrated with Twitter. This means you can watch a show on the top portion of the screen and simultaneously send out tweets in the "Snap" sidebar. An optional bottom pane will show tweets that are tied to whatever TV series is being played.
A major selling point of self-driving cars is what they remove from the road: human error, driver exhaustion, distracted driving because someone has to keep reminding the urchins in the backseat that "No, we’re not there yet, and if you keep asking I'm pulling the car over right now." Less attention has been paid to the new capabilities driverless cars will open up, such as traveling at much higher speeds than a human driver could manage. Carmaker Audi claims they just set a speed record for driverless cars, zooming 149 mph around a racing circuit in (of course) Germany.
In the tense moments of a long-range gun battle, unnecessary movements can give away a combatant's position, cause them to lose sight of the enemy, and possibly lead to fatalities. For America’s special forces, Sandia National Laboratories has developed a new sniper scope that, with the press of a button, adjusts focus. Called Rapid Adaptive Zoom for Assault Rifles (RAZAR), the lens has immediate uses on the battlefield, but in the future, it might just be a birdwatcher's best friend.
In the documentary film "Citizenfour" by Laura Poitras, it’s revealed that Edward Snowden’s longtime girlfriend Lindsay Mills also left the United States and joined Snowden in Russia. Cheekily, Vogue suggests a trio of outfits for Mills, to match both the climate and the need for discretion that comes with proximity to the source of a major intelligence leak.
After crossing multiple time zones it can feel like your entire body is worn out. And it turns out, that’s true, even down to the bacteria in your gut. In a study published last week in the journal Cell, researchers found that in both humans and mice, the gut microbiome was affected by changes to the test subjects' biological clocks. The human subjects went on a trip from the U.S. to Israel -- an eight- to ten-hour time zone difference. The mice in the study didn't get to go anywhere (humans have all the fun), but they had their feeding habits and the light in their habitats disrupted. In both the humans and the mice, the researchers took fecal samples before and after to see which bacteria were thriving in their guts. Not only did they find that the bacteria in the gut changed, they found that the bacteria who thrived under the changing conditions were the ones most associated with obesity and other health issues.
When the first working gun was 3-D printed in the United States, the government responded not through the Bureau of Alcohol, Tobacco, and Firearms, but instead through the State Department. Guns, it turns out, aren’t terribly hard to get in the United States, so a 3-D printed gun doesn’t radically change gun access here. In countries with stricter gun control laws, though, printing a gun is a new risk. This week, Japan sentenced 28-year-old Yoshitomo Imura to two years in prison for printing guns and instructing others on how to print them.
The treatment, developed by researchers in the UK and Poland, involved removing one of Fidyka's olfactory bulbs (the structures in the brain that allow you to smell) growing cells from the bulb, and then injecting those cells into the damaged area of Fidyka's spinal cord. The researchers were interested in cells from the olfactory bulb in particular because the nerves in the olfactory system are the only part of the human nervous system known to regrow after being damaged, with the help of olfactory ensheathing cells.
Now a group of scientists are decoding the mystery surrounding this bizarre disorder. By mapping the genome of each individual in the Pakistan family, researchers from Uppsala University in Sweden identified a single genetic mutation responsible for the condition. Known as ITPR2, the gene is responsible for controlling sweat production, and knocking it out can stop sweat secretion altogether.
