Galileo revisited: How ribbons roll

Galileo Galilei’s experiments on the motions of falling and rolling objects, described in his 1638 book, “Two New Sciences,” are considered by many to be the beginning of modern science. Now researchers at MIT have ...

Single-molecule manipulation for the masses

Scientists have developed a new massively-parallel approach for manipulating single DNA and protein molecules and studying their interactions under force. The finding appears in the June 2 issue of Biophysical Journal.

Device may detect urinary tract infections faster

Urinary tract infections can quickly move from being a merely miserable experience to a life-threatening condition. Untreated cases may trigger sepsis, which occurs when the immune system, in an attempt to fight off the infection, ...

Planet of the Apes: Furry mammals evolved a tuned spin dry

When a wet dog shakes himself dry, he does something amazing. He hits just the right rhythm to maximize the drying effect with minimal effort. The seemingly casual jiggle imparts enough centrifugal force to expel 70 percent ...

An overlooked piece of the solar dynamo puzzle

A previously unobserved mechanism is at work in the Sun's rotating plasma: a magnetic instability, which scientists had thought was physically impossible under these conditions. The effect might even play a crucial role in ...

Engineering a new spin for disease diagnostics

Researchers at the National University of Singapore have created a new platform with the potential to extract tiny circulating biomarkers of disease from patient blood. This simple, fast and convenient technique could help ...

A new telescope probes a young protostar

(Phys.org) —IRAS 16293-2922B is a very young star – a protostar - perhaps only about ten thousand years old. Slightly smaller in mass than our Sun, it is still deeply embedded in its surrounding natal material, and apparently ...
