Pulling, not pushing, silk could revolutionize how greener materials are manufactured

( University of Sheffield) New insights into how animals spin silk could lead to new, greener ways of producing synthetic fibres, according to academics at the University of Sheffield.

Lack of trust less of a barrier to clinical trial participation, say minority populations

( Research!America) Significantly fewer African-Americans, Hispanics, Asians and non-Hispanic whites say 'lack of trust' is a reason why individuals do not participate in clinical trials, indicating a more favorable perception of this research. In a recent public opinion survey commissioned by Research!America, the percentage of respondents citing 'lack of trust' as a reason declined by as much as 15% among minority groups and the population overall, compared to the results of a 2013 survey.

Tiny lasers from a gallery of whispers

( American Institute of Physics) Whispering gallery mode resonators rely on a phenomenon similar to an effect observed in circular galleries, and the same phenomenon applies to light. When light is stored in ring-shaped or spherical active resonators, the waves superimpose in such a way that it can result in laser light. This week in APL Photonics, investigators report a new type of dye-doped WGM micro-laser that produces light with tunable wavelengths.

Security cameras are vulnerable to attacks using infrared light -- Ben Gurion U. study

( American Associates, Ben-Gurion University of the Negev) The cyber team led by Dr. Mordechai Guri, head of research and development for BGU's Cyber Security Research Center (CSRC), shows how IR can be used to create a covert communication channel between malware installed on an internal computer network and an attacker located hundreds of yards outside or even miles away with direct line of sight. The attacker can use this channel to send commands and receive response messages.

Landmark study suggests risks vary widely in drone-human impacts

( Virginia Tech) New Virginia Tech research suggests there's wide variation in the risk that unmanned aircraft pose to people on the ground.

Clear tactics, but few easy solutions, for hospitals combating ransomware

( Brown University) Hospitals facing the prospect of ransomware attacks like the one that afflicted British hospitals in May can take many concrete steps to better protect themselves, but some of the most important measures -- such as a national policy not to pay ransoms -- may be tougher to formulate.

Political polarization? Don't blame the web, Brown study says

( Brown University) Despite the popular narrative that the web is to blame for rising political polarization, a study by a Brown University economist has found that recent growth in polarization is greatest for demographic groups in which individuals are least likely to use the internet and social media. This means that data does not support the claim that the internet is the most significant driver of partisanship.

Researchers use Wikipedia to give AI context clues

( Brigham Young University) A team of BYU computer scientists is teaching artificial intelligence agents how to interact with the world in a way that makes sense.

A study switches from genetic to metabolic analysis to reconstitute evolutionary process

( Fundação de Amparo à Pesquisa do Estado de São Paulo) A new method for analyzing a living being chemical compositions is tested in Andean plants and attest the genesis of species by means of geographic isolation. Scientific article published August 2017 by Brazilian researchers is based on the analysis of chemical compounds which express specific biogeographic trends at the evolutionary process, validating a Smithsonian hypothesis on the evolution of the genus Espeletia in the process.

NASA data shows Otis devoid of precipitation, now a remnant

( NASA/Goddard Space Flight Center) Former Hurricane Otis was not showing any thunderstorm development or precipitation on satellite imagery on Sept. 19. As a result, the National Hurricane Center declared Otis a remnant low pressure area.
