Last week we brought you the news that scientists have now found a way to deduce which colors dinosaurs may have been by analyzing the structure of melanosomes. Those are cell bodies which carry melanin, which determines color, and in the case of the Sinosauropteryx had survived in fossils. Unfortunately there’s some bad news to […]
Traditional lab tests for disease diagnosis can be too expensive and cumbersome for the regions most in need. George Whitesides’ ingenious answer, at TEDxBoston, is a foolproof tool that can be manufactured at virtually zero cost. Check it out:
We’ve read the books, we’ve seen the movies (lots of them), but what does a real physicist say about time travel? Sean Carroll of the blog Cosmic Variance is a Senior Research Associate in the Department of Physics at the California Institute of Technology. He wrote a book called From Eternity to Here: The Quest […]
If you’ve watched Western movies you’ll know that most of the time there’s a predictable pattern to shootouts: the villain draws his gun first, but the hero shoots quicker and wins (before blowing the smoke from the tip of the barrel.)

But that’s just one example of the curious historical methods we use to guess what the weather will be, with mixed results. The basis of Groundhog Day is that if, […]
Mechanical and aerospace engineering professor Afsaneh Rabiei recently invented a new material that is actually stronger than stainless steel but lighter than aluminum. Rabiei’s metal foam is primarily made out of hollow steel spheres surrounded by aluminum. According to the following news report, it can absorb seven to eight times the energy absorbed by other […]
It appears that some young girls struggling with mathematics may be picking up on a lack of confidence in their female teacher. But the same research also shows this effect is far from guaranteed and can be outweighed by strong role models at home. Before going further, it’s very important to note that the study, […]
The following video will give you a quick peak at what a typical work day is for Rhaana Starling and Phil Evans, two astrophysicists studying gamma ray bursts at the University of Leicester, England
