Nano-level lubricant tuning improves material for electronic devices and surface coatings Posted: 10 Feb 2017 01:59 PM PST Researchers have developed a new approach to dynamically tune the micro- and nano-scale roughness of atomically thin MoS2, and consequently the appropriate degree of hydrophobicity for various potential MoS2-based applications.

Exploring mysteries on the surface Posted: 10 Feb 2017 10:13 AM PST Scientists have discovered the unique properties of two-dimensional (2D) materials and metals grown on graphene, graphite, and other carbon coated surfaces.

Breaking research could help to combat rise in drivers impaired by edible marijuana consumption Posted: 10 Feb 2017 10:12 AM PST Though marijuana edibles are becoming increasingly common, scant information exists on how to test drivers for impairment following their consumption. For the first time, research evaluates the performance of roadside saliva tests for tetrahydrocannabinol (THC) following consumption of edibles, showing that lower THC cutoff points are needed for these tests to effectively detect marijuana ingestion.

Stressed out interferons reveal potential key to alternative lupus treatment Posted: 10 Feb 2017 10:10 AM PST New research has identified a previously unknown mechanism involved in the immune response that could provide an alternative therapy target for treating the estimated 1.5 million Americans and five million-plus people worldwide suffering from lupus.

Bluebells may fail to flourish as warmer days speed start of spring Posted: 10 Feb 2017 10:09 AM PST Bluebells and some other spring flowers appear to be slipping out of sync with spring, as changes in seasonal temperatures alter the optimum time for them to come into leaf or flower, a new study has found.

Laser-based camera improves view of the carotid artery Posted: 10 Feb 2017 10:09 AM PST Novel technology has been used to monitor vulnerabilities for cardiovascular events, aid in diagnosis and treatment.

Poverty, high neighborhood murder rates increase depression in older adults Posted: 10 Feb 2017 05:45 AM PST Older adults who live in poor and violent urban neighborhoods are at greater risk for depression, a study has found.

Malaria vaccine target's invasion partner uncovered Posted: 10 Feb 2017 05:45 AM PST A team has discovered how a promising malarial vaccine target -- the protein RH5 -- helps parasites to invade human red blood cells. The study reveals that a previously mysterious protein on the surface of the parasite called P113 provides a molecular bridge between the parasite and a red blood cell. The discovery could be used to make a more effective malaria vaccine.
