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 / 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 / Altered colony chemistry reveals a process that destroys termite societies
Several insect species, including ants, honeybees and termites, live in highly organized societies, also known as social insect colonies. Insects living in these colonies can take on different roles, such as reproducing, ...
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 / Tumor DNA circulating in patients' blood after pre-surgery treatments predicts whether breast cancer will return
Fragments of tumor DNA circulating in the bloodstream of patients with breast cancer can predict whether they are likely to relapse, especially when samples are taken after the patients have received treatments prior to surgery. ...
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 / Hearing research traces evolution of key inner ear protein
In the intricate machinery of the inner ear, hearing begins with a protein that moves a few billionths of a meter up to 100,000 times per second. That protein, called TMC1, sits at the tips of sensory hair cells deep in the ...
Phys.org / Advanced dating method reveals age of Pacific coral architecture
Application of an advanced dating technique establishes the first precise construction timeline for houses built out of coral in French Polynesia. The findings reveal previously hidden patterns of architectural development ...
Phys.org / Making quantum vibrations nonlinear to enable phonon-phonon interactions
Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric currents. Because phonons can ...
Phys.org / Researchers use quantum biosensors to peer into cells' inner workings
In a major advance applying insights from quantum physics to the inner workings of biology, a team of WashU researchers has successfully implanted quantum sensors in living cells to measure shifts in magnetism and temperature. ...
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 / Sewage overflows may pose greater threat to England's rivers than previously thought
Combined sewer overflows (CSOs) could be contributing far more pollution to England's rivers than previously recognized, according to new research involving scientists from Imperial College London and Brunel University London. ...
