DNA is held together by hydrophobic forces

( Chalmers University of Technology) Researchers at Chalmers University of Technology, Sweden, disprove the prevailing theory of how DNA binds itself. It is not, as is generally believed, hydrogen bonds which bind together the 2 sides of the DNA structure. Instead, water is the key. The discovery opens doors for new understanding in research in medicine and life sciences. The researchers' findings are presented in the journal PNAS.

Keren Bergman wins $4.8M DARPA grant

( Columbia University School of Engineering and Applied Science) Grant supports the development of a new class of on-chip optical interconnects that scale performance without increasing energy costs.

Lab develops novel approach to study sound recognition in acoustically orienting animals

( St. Olaf College) A new study by Dr. Norman Lee, in collaboration with St. Olaf College students Alexander Kirtley '19, Isaiah Pressman '19, and Karina (Kari) Jirik '20, and University of Toronto collaborators Dean Koucoulas and Dr. Andrew C. Mason, show a novel approach that can be used to study song recognition in O. ochracea.

NASA catches Tropical Storm Tapah by the tail

( NASA/Goddard Space Flight Center) Tropical Storm Tapah has a huge 'tail' on NASA satellite imagery. NASA's Terra satellite captured an image of the northwestern Pacific Ocean storm that revealed a large band of thunderstorms that resemble a large tail. The NASA imagery also indicated that the storm is getting better organized.

NASA finds a tiny tropical storm Kiko

( NASA/Goddard Space Flight Center) NASA's Terra satellite is one in a fleet of NASA satellites that provide data for research. Terra captured an image of Tropical Storm Kiko in the Eastern Pacific Ocean which showed the extent of the small storm.

Evolution of learning is key to better artificial intelligence

( Michigan State University) Researchers at Michigan State University say that true, human-level intelligence remains a long way off, but their new paper published in The American Naturalist explores how computers could begin to evolve learning in the same way as natural organisms did -- with implications for many fields, including artificial intelligence.

Water may be scarce for new power plants in Asia

( Ohio State University) Climate change and over-tapped waterways could leave developing parts of Asia without enough water to cool power plants in the near future, new research indicates. The study found that existing and planned power plants that burn coal for energy could be vulnerable. The work was published today in the journal Energy and Environment Science.

Long-acting injectable multi-drug implant shows promise for HIV prevention and treatment

( University of North Carolina Health Care) UNC researchers have created an injectable multi-drug delivery system that is removable, biodegradable and effective for up to a year in some cases. First author Rahima Benhabbour, PhD, MSc, says the ability to administer multiple drugs with this implant is an important advancement in this research.

Today's forecast: How to predict crucial plasma pressure in future fusion facilities

( DOE/Princeton Plasma Physics Laboratory) Feature describes improved model for forecasting the crucial balance of pressure at the edge of a fusion plasma.

New method for the measurement of nano-structured light fields

( University of Münster) Physicists and chemists at the University of Münster (Germany) have jointly succeeded in developing a so-called nano-tomographic technique which is able to detect the typically invisible properties of nano-structured fields in the focus of a lens. Such a method may help to establish nano-structured light landscapes as a tool for material machining, optical tweezers, or high-resolution imaging. The study was published in "Nature Communications".
