For two molecules on blind date, new method predicts potential for attraction or repulsion

Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs.

The research is reported as a communication in the April 27 issue of the Journal of Chemical Physics, which is the most highly cited journal in atomic, molecular and chemical physics according to Thomson Reuters. The journal is published by the American Institute of Physics. Despite appearing at the end of April, the paper was on the list of the 20 most-read articles in JCP for that month. (more…)

Using the latest satellite tracking technology, conservationists from the Wildlife Conservation Society, the University of Exeter and the Government of Mexico have completed a ground-breaking study on a mysterious ocean giant: the manta ray.

The research team has produced the first published study on the use of satellite telemetry to track the open-ocean journeys of the world’s largest ray, which can grow up to 25 feet in width.

Researchers say the manta ray—listed as ‘Vulnerable’ by the International Union for the Conservation of Nature (IUCN)—has become increasingly threatened by fishing and accidental capture and now needs more protection. (more…)

New Twist on Ancient Math Problem Could Improve Medicine, Microelectronics

ANN ARBOR, Mich.— A hidden facet of a math problem that goes back to timeworn Sanskrit manuscripts has just been exposed by nanotechnology researchers at the University of Michigan and the University of Connecticut.

It turns out we’ve been missing a version of the famous “packing problem,” and its new guise could have implications for cancer treatment, secure wireless networks, microelectronics and demolitions, the researchers say.

Called the “filling problem,” it seeks the best way to cover the inside of an object with a particular shape, such as filling a triangle with discs of varying sizes. Unlike the traditional packing problem, the discs can overlap. It also differs from the “covering problem” because the discs can’t extend beyond the triangle’s boundaries. (more…)

Cloud services reduce time and money spent managing security and increase protection against cyberthreats, Microsoft study shows.

REDMOND, Wash. — Research released today by Microsoft Corp. shows that small and midsize businesses (SMBs) are gaining significant IT security benefits from using the cloud, according to a new Microsoft study in five geographies.

The study shows that 35 percent of U.S. companies surveyed have experienced noticeably higher levels of security since moving to the cloud.1 In addition, 32 percent say they spend less time worrying about the threat of cyberattacks. U.S. SMBs using the cloud also spend 32 percent less time each week managing security than companies not using the cloud. They are also five times more likely to have reduced what they spend on managing security as a percentage of overall IT budget. (more…)
