Study sheds light on concerning new trend in drug advertising: Patient influencers — ScienceDaily
Patients-turned-social-media-influencers routinely offer prescription drug advice to their followers and often have close ties with pharmaceutical companies, according to new University of Colorado Boulder research. But they also tend to…
New discovery sheds light on very early supermassive black holes — ScienceDaily
Astronomers from the University of Texas and the University of Arizona have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early…
Using an alternate light source could help nurses and police detect bruises on darker skin, research says
CNN — Sexual assault and domestic violence injuries, like bruises, can be challenging to spot on darker skinned victims under the standard white light found in most exam rooms. New…
Unique, chip-based light source allows scanning lidar to be combined with 3D flash lidar — ScienceDaily
Our roads might one day be safer thanks to a completely new type of system that overcomes some of lidar’s limitations. Lidar, which uses pulsed lasers to map objects and…
Researchers devise a new path toward ‘quantum light’ — ScienceDaily
Researchers have theorised a new mechanism to generate high-energy ‘quantum light’, which could be used to investigate new properties of matter at the atomic scale. The researchers, from the University…
A study sheds new light on chemical processes that cause marine bacteria to switch from coexistence with an algae host to killer mode — ScienceDaily
Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results…
A search for variable stars called RR Lyrae has found some of the most distant stars in the Milky Way’s halo a million light years away — ScienceDaily
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo. The most distant of these stars is more than a…
Nanoplastics unexpectedly produce reactive oxidizing species when exposed to light — ScienceDaily
Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make…
Plants between light and darkness — ScienceDaily
For research, plants are frequently grown under stable lighting, which does not reflect natural conditions. In a series of experiments with changing light conditions, simulating the natural interplay of light…
