Huawei arrest tests China’s leaders as fear and anger grip elite

Unlike a new round of tariffs, the detention of Meng appears to have driven home the intensifying rivalry between the United States and China in a visceral way for the Chinese establishment. from telecom-equipment - Telecom News | Latest Telecom Industry News, Information and Update: ET Telecom : ETTelecom.com https://telecom.economictimes.indiatimes.com/news/huawei-arrest-tests-chinas-leaders-as-fear-and-anger-grip-elite/66999410?utm_source=RSS&utm_medium=ETRSS

Molecular insights into spider silk

Spider silk belongs to the toughest fibers in nature and has astounding properties. Scientists have now discovered new molecular details of self-assembly of a spider silk fiber protein. from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207112741.htm

More bioplastics do not necessarily contribute to climate change mitigation

Bioplastics are often promoted as an environmentally and climate-friendly alternative to conventional petroleum-based plastics. However, a recent study suggests that shifting to plant-based plastics could have less positive effects than expected. Specifically, an increased consumption of bioplastics in the following years is likely to generate increased greenhouse gas emissions from cropland expansion on a global scale. from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207112714.htm

Half a million tests and many mosquitoes later, new buzz about a malaria prevention drug

Researchers spent two years testing chemical compounds for their ability to inhibit the malaria parasite at an earlier stage in its lifecycle than most current drugs, revealing a new set of chemical starting points for the first drugs to prevent malaria instead of just treating the symptoms. from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181206141227.htm

NASA InSight lander 'hears' Martian winds

NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport InSight lander, which touched down on Mars just 10 days ago, has provided the first ever "sounds" of Martian winds on the Red Planet. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207164927.htm

NASA's Mars InSight flexes its arm

New images from NASA's Mars InSight lander show its robotic arm is ready to do some lifting. With a reach of nearly 6 feet (2 meters), the arm will be used to pick up science instruments from the lander's deck, gently setting them on the Martian surface at Elysium Planitia, the lava plain where InSight touched down on Nov. 26. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207164728.htm

Planetary defense: The Bennu experiment

On Dec. 3, after traveling billions of kilometers from Earth, NASA's OSIRIS-REx spacecraft reached its target, Bennu, and kicked off a nearly two-year, up-close investigation of the asteroid. It will inspect nearly every square inch of this ancient clump of rubble left over from the formation of our solar system. Ultimately, the spacecraft will pick up a sample of pebbles and dust from Bennu's surface and deliver it to Earth in 2023. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207164535.htm

A new 'spin' on kagome lattices

The kagome ferromagnet Fe3Sn2 exhibits an electronic state that couples unusually strongly to an applied magnetic field that can be rotated to point in any direction of a 3-dimensional space, revealing that magnetization drives -- in quantum scale -- a 'giant' energy shift within the material, an international team of researchers has found. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207154256.htm

Researchers probe hydrogen bonds using new technique

Researchers have used nuclear resonance vibrational spectroscopy to probe the hydrogen bonds that modulate the chemical reactivity of enzymes, catalysts and biomimetic complexes. The technique could lead to the development of better catalysts for use in a wide range of fields. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2018/12/181207144408.htm
