“#’Light squeezer’ reduces quantum noise in lasers, could enhance quantum computing and gravitational-wave detection” Credit: CC0 Public Domain Physicists at MIT have designed a quantum “light squeezer” that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable…
“#Cooling mechanism increases solar energy harvesting for self-powered outdoor sensors” An illustration of thermoelectric devices using a wavelength-selective emitter and a broadband emitter. The device using a broadband emitter experiences a voltage drop due to environmental temperature changes, while the device with a selective emitter remains constant thanks to daytime radiative cooling.

“#Protein linked to cancer acts as a viscous glue in cell division” The protein PRC1, a telltale sign in many cancer types including prostate, ovarian, and breast cancer, act as a “viscous glue” during cell division, precisely controlling the speed at which two sets of DNA are separated as a single cell divides.

“#Colleges that emphasize activism have more civically engaged students” Credit: CC0 Public Domain Students tend to be more engaged in activism if the school that they attend emphasizes social and political issues, according to new research featuring faculty at Binghamton University, State University of New York. A research team including Binghamton University Assistant Professor of…
“#The study of lysosomal function during cell division and chromosomal instability” Dra. Caroline Mauvezin group. Credit: Bellvitge Biomedical Research Institute (IDIBELL) A team from the Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona (UB), in collaboration with a researcher from the Mayo Clinic and the University of Minnesota, have described that lysosomes and…
“#Video: How COVID-19 is affecting support for mail-in voting” Credit: CC0 Public Domain How will opinions change as cases across the country fluctuate—particularly in states, such as Arizona or Florida, where cases are rising sharply? . That’s the question, says David Lazer, university distinguished professor of political science and computer and information sciences at Northeastern….
“#Tree rings show unprecedented rise in extreme weather in South America” Araucaria araucana trees in northern Patagonia, Argentina, some of which were used in the study. Some trees can live 1,000 years. Credit: Ricardo Villalba, Argentine Institute of Snow, Glacier and Environmental Sciences, at the National Research Council for Science and Technology Scientists have filled…
“#Evolution makes the world less ragged” Credit: Pixabay/CC0 Public Domain How does evolution impact ecological patterns? It helps smooth out the rough edges, says UConn Ecology and Evolutionary Biology Professor Mark Urban. Urban led an international team of researchers through a review of the history of ecological and evolutionary research to establish a framework to…
“#Physics team observes extremely fast electronic changes in real time in a special material class” Topological materials such as tungsten ditelluride, here a sample in an ultra-high vacuum chamber, have special electronic properties and are very robust against external perturbations. Credit: AG Bauer In physics, they are currently the subject of intensive research; in electronics,…
“#Bores’ lasting effect on landscape” Faure Island in Shark Bay, Western Australia. Credit: Graham Fulton Artificial watering points in rangelands are posing an increasing threat to surrounding biodiversity long after the removal of livestock, according to University of Queensland research. UQ researcher Graham Fulton studied the behaviour and impact of 20 bird species on Faure…
