Research provides insights on World War II naval battle site



Posted: 12 Jun 2018 05:18 PM PDT


A new study provides precise geographic information for the preservation, long-term research, and future use of a historically important World War II battle site on the seafloor off the coast of Okinawa, Japan.


Core electron topologies in chemical bonding



Posted: 12 Jun 2018 03:51 PM PDT


Researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides for the first time reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. Other elements with a similar propensity as carbon to reshape their core electron nodal structures upon chemical bonding are proposed.


Physicists discover how to create the thinnest liquid films ever



Posted: 12 Jun 2018 07:57 AM PDT


Physicists have discovered a fundamentally new way surfaces can get wet. Their study may allow scientists to create the thinnest films of liquid ever made -- and engineer a new class of surface coatings and lubricants just a few atoms thick.


Breakthrough in lignin research: Spherical particles multiply enzyme efficiency



Posted: 12 Jun 2018 07:57 AM PDT


Lignin, a pulp industry by-product, could replace fossil materials.


Graphene carpets: So neurons communicate better



Posted: 12 Jun 2018 07:57 AM PDT


Scientists have experimentally observed the phenomenon of ion 'trapping' by graphene carpets and its effect on the communication between neurons. The researchers have observed an increase in the activity of nerve cells grown on a single layer of graphene. Combining theoretical and experimental approaches they have shown that the phenomenon is due to the ability of the material to 'trap' several ions present in the surrounding environment on its surface, modulating its composition.


New optical sensor can determine if molecules are left or right 'handed'



Posted: 12 Jun 2018 07:57 AM PDT


A team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality -- a property of molecular spatial twist that defines its biochemical properties.


Putting animals in their best light: Some shades of LED lamps threaten wildlife



Posted: 12 Jun 2018 06:06 AM PDT


A research team identifies harmful effects to wildlife as LED lights proliferate. Some hues, including blues and whites, imperil creatures while other wavelengths are more benign. They devised an interactive web-based tool to help people make wildlife-friendly choices in outdoor lighting.


Neutrinos weighed by the world's most precise scale



Posted: 12 Jun 2018 05:36 AM PDT


What is the mass of neutrinos? To answer one of the most fundamental and important open questions in modern particle physics and cosmology, the KATRIN Karlsruhe Tritium Neutrino Ex-periment was designed and built.


Basketball teams playing for survival in critical NBA playoffs are more likely to lose



Posted: 12 Jun 2018 05:00 AM PDT


A new study finds that basketball teams playing for survival in critical NBA playoff games are more likely to lose. This study is the first to illustrate 'choking' in a real-world team sports environment. The results suggest that 'choking' is a common phenomenon in high-stakes situations and may be applicable to a variety of high-pressure performance situations, including those found in the workplace.


Multiple lasers could be replaced by a single microcomb



Posted: 12 Jun 2018 05:00 AM PDT


Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb.
