Phys.org / Why no individual is like another when epigenetics come into play
Why do animals behave differently, and what are the consequences of this? A research team from the Collaborative Research Center NC³ at Bielefeld University and the University of Münster now provides a new explanation: epigenetic ...
Phys.org / Silicon nanospheres boost WS₂ second-harmonic generation 40-fold while preserving polarization
A research team has demonstrated that silicon nanospheres can strongly enhance second-harmonic generation (SHG) from an atomically thin semiconductor while preserving the circular polarization information tied to its valley ...
Medical Xpress / Replacing TV time with reading or desk work may lower dementia risk
New research distinguishing between passive and mentally active sitting in association with dementia has found that adults who engaged in extended durations of mentally passive sedentary behaviors had a higher risk of dementia. ...
Phys.org / Birds of prey act as sentinels to warn of forever chemicals
A new paper investigates how raptors, or birds of prey like hawks and eagles, act as a sentinel species that can reveal the level of forever chemicals in the local environment. The forever chemicals, or PFAS, are especially ...
Phys.org / From simulation to strategy: Climate modeling motivates action at the top
New research by MIT Sloan School of Management finds that global leaders who participate in facilitated engagements using an interactive climate policy simulator, En-ROADS, demonstrated a stronger understanding of climate ...
Phys.org / Trapped subsurface heat may have triggered Antarctica's sudden sea ice loss
In 2016, Antarctic sea ice, which had previously shown record expansion, shifted rapidly toward unusually low levels. This abrupt shift left scientists scratching their heads, wondering why it had vanished so quickly despite ...
Phys.org / Seismic activity in California varies with the seasons
Earthquakes occur when the tectonic plates of the Earth's crust shift, jolting past each other in a release of built-up tension. However, other natural forces can also influence seismic activity: Hydrological dynamics, like ...
Phys.org / The earliest dogs in Europe: 14,200-year-old DNA helps reveal their identity
An international team of researchers led by the Francis Crick Institute, the University of East Anglia and the Max Planck Institute for Evolutionary Anthropology has found that dogs were domesticated more than 14,000 years ...
Phys.org / Radio signals at the edge of extreme stars come from far beyond their surfaces
Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the ...
Medical Xpress / Nicotine e-cigarettes found to be more successful in helping smokers quit
A new analysis of existing studies co-led by a University of Massachusetts Amherst public health researcher finds that nicotine e-cigarettes consistently help adults quit smoking, a conclusion that emerges with striking agreement ...
Phys.org / Red-tailed bumblebees found to be key hosts for dangerous bee virus
Wild bumblebees serve as key hosts for acute bee paralysis virus. While the virus appears to cause little harm to bumblebees, infection is usually fatal to honeybees. Until now, it was assumed that honeybees were the key ...
Phys.org / Study finds 60% of Australia's top-use pesticides are banned in the EU
Analysis of Australia's highest-volume pesticide use has revealed that the majority of products widely used in Australian agriculture are banned in other parts of the world, according to a new study. Researchers from Griffith's ...
