Despite the ethical and political differences they incite, stem cells are still a miraculous medicine, potentially able to change into whatever a sick body needs them to be. If we could get around the controversies behind them, theoretically, the problems would be gone.
Researchers have just discovered that gibbons not only compete with our top ranks of singers--they have the technique down pat with almost no effort. How did we find this out? By gassing them with helium and listening in on the results, of course.
After 50 years of research, we've discovered a strange, beautiful fact about our Sun: it's more perfectly round than anything else in the natural world. It's not the roundest in a certain category; it's just the roundest sphere there is. If it were a beach ball, The Guardian writes, it would be a hair's width away from complete perfection.
If you've seen the board-breaking power of a professional martial artist and thought it looked superhuman, don't worry: for a while now science couldn't fully explain it, either. The punches delivered by a top-notch fighter are so tough that muscle strength alone can't account for them. But researchers from Imperial College London and University College London have discovered that a unique brain structure could be what gives experts fists of fury.
You are unique. This is one of the more obscure ways you're unique: An alternating current of different frequencies running through you causes a reaction that's noticeably different from anyone else's. Researchers from Dartmouth University are trying to put this difference to use by creating wearable electronics that respond to--and only to--their intended user.
It's not in doubt that global warming is changing the planet for the worse, but it's difficult to identify which, if any, specific weather events we can definitively link to it. But a new (and divisive) paper from senior NASA climate scientist James E. Hansen suggests that global warming is almost definitely the cause of heat waves and other events observed in the last decade.
There are a lot of hurdles to accurately predicting intelligence, from the difficulty of defining exactly what it is to accurately understanding the complexities of the human brain. Some techniques are surprisingly simple, like measuring the size of the brain. But others, like a new study that suggests brain imaging could crack the IQ code, require a little more finesse.
The majority of engineers are men. The majority of U.S. Army soldiers are also men. So when a new piece of equipment is being designed--equipment that could change the outcome of a life or death situation--it's made with men in mind. Then, if women need it, they might just have to shoehorn themselves into the male variety, as is currently the case with body armor. But the Army recently announced it'll try to change that by testing new body armor built for women.
