Generations of sweating architects and designers have been at work for hundreds of years, pulling inspiration from different sources, to give the biggest, most iconic cities in the world their unique looks. The result is a Paris that isn't the same as New York and a Barcelona that isn't the same as Tokyo. We can pick up on the subtle differences, and now new software can, too.
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.
The jury is still out, in many respects, on exactly what depression is and how it should be treated, but clinically speaking it is usually diagnosed in a psychological rather than a physiological manner--that is, via a questionnaire that is given to patients rather than by some method of empirical testing. But The Atlantic reports that a new study has shown that blood tests can diagnose depression--a finding that could change the way depression is both diagnosed and viewed by patients.
Major League Baseball pitchers can't wear white gloves or wristbands because they obscure the ball, making it difficult for batters to gauge a pitch's path. Professional table-tennis players aren't allowed to wear clothes that match the ball for similar reasons, but there are no such rules in tennis.
Studies on the impact of wireless radiation on humans are endlesslyinconclusive, but a recent study on the effects of Wi-Fi radiation on trees--yes, trees--indicates that our woody friends may be much more vulnerable than we are.
But the long-term effects of prolonged cellphone use require further study—and will spark fresh controversy

When I was reporting my March 2010 PopSci feature story on the possible health effects of cell phone radiation, I was particularly interested in learning about the Interphone project, a collection of 13 different national studies coordinated by the International Agency for Research on Cancer (IARC), part of the World Health Organization.
Interphone is the largest completed analysis to date of brain tumor (glioma and meningioma) risk in relation to mobile phone use. When I was writing my piece, none of the scientists I interviewed could or would say much about the study, since it had yet to be published. So not much about Interphone ended up in my story. But when I asked one source familiar with the study's progress what we would learn once the results appeared, this person said: "We'll learn how to do better studies."
Well, the Interphone study has finally appeared and, unfortunately, my source was right.
Testing AIDS vaccines can get ethically tricky in human volunteers. That's why MIT has engineered a more "humanized" mouse that has human immune cells, and could become the experimental model of choice involving vaccines for AIDS and other diseases.
The lab mice now display a wide array of human immune cells for the first time. Among the cells are Natural Killer (NK) cells that seek and destroy infected cells, as well as macrophages and dendritic cells that can swallow pathogens or recruit more immune cells to the fight.
Today, a company called DeepDyve launched the largest online rental service for scientific papers, which allows users to rent any article for just 99 cents. Journal articles currently trend toward the obscene ($30 or more), unless you're the lucky dude with a password for a university library. DeepDyve saw an opening in the market and made deals with major scientific publishers to stock 30 million (and growing) articles of tech, med, and scientific interest.
DeepDyve is part of a greater trend of getting scientific info back to the hardworking taxpayers who funded it.
At the so-called Restaurant of the Future in Wageningen, Netherlands, lunch time diners have all sorts of food options. “Animal friendly” meats, fruit juices, cheese slices, bananas, waffles, pretty much anything to suit your appetite. And, you can eat a full meal for only $6.30; it’s a great deal. A deal, that is, as long as you don’t mind a team of scientists studying you as you hit the buffet.
