NASA Goddard technology helps fight forest pests

( NASA/Goddard Space Flight Center) A joint operation using technology developed at NASA's Goddard Space Flight Center in Greenbelt, Md., will help the US Forest Service understand the impacts of pests on northeastern trees.

Tool helps public health agencies prioritize health risks

( University of Missouri-Columbia) Public health agencies across the globe are challenged with preventing the spread of chronic diseases while dealing with limited funds and devastating budget cuts. Now, a researcher at the University of Missouri has applied the Public Health Index model, a tool he designed that has been adopted by the Missouri Department of Health and Senior Services, to help the Brazilian government identify and prioritize health risks affecting its population.

Half of the most popular news on Twitter is not covered by traditional news media sources

( Carlos III University of Madrid) Half of the news that appears on Twitter as 'trending topics' goes unmentioned in the traditional news media, and when both sources carry it, 60 percent of the stories appear first on the social network. Those are some of the conclusions of a study which analyzes the dissemination of news on Twitter compared with the traditional media.

Transparent, electrically conductive network of encapsulated silver nanowires

( Helmholtz-Zentrum Berlin für Materialien und Energie) A team headed by Professor Silke Christiansen has developed a transparent electrode with high electrical conductivity for solar cells and other optoelectronic components -- that uses minimal amounts of material. It consists of a random network of silver nanowires that is coated with aluminium-doped zinc oxide. The novel electrode requires about 70 times less silver than conventional silver grid electrodes, but possesses comparable electrical conductivity.

New Smart Villages offgrid solutions for helping world's bottom billion

( Richard Hayhurst Associates) A new series of essays by leading experts maintains that the latest offgrid energy solutions can provide sustainable development for the world's bottom billion and meet upcoming Sustainable Development Goals.

Protein machines make fluctuating flows unconsciously

( Hiroshima University) An international research group has demonstrated that protein machines, regardless of their specific functions, can collectively induce fluctuating hydrodynamic flows and substantially enhance the diffusive motions of particles in the cell.

Heating and cooling with light leads to ultrafast DNA diagnostics

( University of California - Berkeley) UC Berkeley researchers used LEDs and a thin film of gold to turbocharge the heating and cooling cycles of the PCR test so results are ready in minutes, not hours. The innovation greatly expands the clinical and research applications of a workhorse lab tool used in forensics, medical diagnostics and more.

Butterflies heat up the field of solar research

( University of Exeter) The humble butterfly could hold the key to unlocking new techniques to make solar energy cheaper and more efficient, pioneering new research has shown.

Findings in research on photoaging could reverse negative impact of ultraviolet radiation

( InSilico Medicine, Inc.) Photoaging is a process that occurs when human skin is exposed to UV radiation from the sun that causes it to age at a faster rate than it would under normal circumstances. Though the process is known to occur how it works is not fully understood. InSilico Medicine's GeroscopeTM software provided insights into this process that could help to combat it. The research will be presented at Basel Life Science Week 2015.

Stanford team's brain-controlled prosthesis nearly as good as one-finger typing

( Stanford School of Engineering) Brain-controlled prostheses sample a few hundred neurons to estimate motor commands that involve millions of neurons. Sampling errors can reduce the precision and speed of thought-controlled keypads. A Stanford-led technique can analyze this sample and make dozens of corrective adjustments in the blink of an eye to make thought-controlled cursors more precise.
