Inbreeding can reduce cooperation in banded mongooses according to a recent study by researchers.
A new study finds that the decision to purchase a gun after mass shootings is driven by fear of stricter regulations on gun purchase and ownership more than by a desire to protect oneself. The work is led by Maurizio Porfiri, Institute professor at NYU Tandon, his second in a year to examine causative factors driving consumer firearm-purchase behavior.
Machine learning can assess the effectiveness of mathematical tools used to predict the movements of financial markets, according to new Cornell research based on the largest dataset ever used in this area.
Scientists have made a key discovery thanks to stardust found in meteorites, shedding light on the origin of crucial chemical elements.
SUTD researchers 3D printed a micro-scaled physical device to demonstrate a new level of control in the directed differentiation of stem cells, enhancing the production of cardiomyocytes.
Contrary to popular wisdom, daily social media use is not a strong or consistent risk factor for depressive symptoms among adolescents, according to a new study by Columbia University Mailman School of Public Health researchers. The results are published in the Journal of Adolescent Health.
There may soon be a new weapon in the centuries-old battle against anthrax in wildlife thanks to groundbreaking work at the Texas A&M University College of Veterinary Medicine & Biomedical Sciences.
* Patients with glioma - a very common type of tumour originating in the brain - see improvement in survival rates with combined treatment of radiotherapy plus temozolomide* Researchers found a novel mechanism on how tumours evade chemotherapy through genomic rearrangements of the MGMT DNA repair gene* This finding is potentially relevant for updating the methods used to monitor temozolomide...
UBC researchers are raising the alarm about the increase of vaping among teenagers and how e-cigarette marketing strategies target youth. Assistant Professor Laura Struik, who teaches in UBC Okanagan's School of Nursing, recently published a paper examining why teens take up vaping and whether advertising capitalizes on those reasons.
A new study published today demonstrates that a technology developed at the University of Central Florida could serve as a more reliable clinically-based model of amyotrophic lateral sclerosis (ALS) and a better screening tool for novel therapies than currently use preclinical models.
Of ever-increasing concern for operating a tactical communications network is the possibility that a sophisticated adversary may detect friendly transmissions. Army researchers developed an analysis framework that enables the rigorous study of the detectability of ultraviolet communication systems, providing the insights needed to deliver the requirements of future, more secure Army networks.
Research published in DeGruyter's International Journal of Adolescent Medicine and Health suggests TikTok is rich with untapped educational potential. The platform could play a vital role in conveying important health information alongside lip-syncing videos and viral dance challenges, the paper's authors say.
UC Riverside engineering professors Mihri and Cengiz Ozkan and their students have been working for years on creating improved energy storage materials from sustainable sources, such as glass bottles, beach sand, Silly Putty, and portabella mushrooms. Now they have turned plastic soda bottles into a nanomaterial for use in batteries. Though they don't store as much energy as lithium-ion batteries,...
In Physics of Fluids, scientists report calculations with a model of a conical-shaped root canal inside a tooth. A crucial step in this common dental procedure is irrigation, or rinsing, of the root canal cavity with an antibacterial solution, and the researchers used computational fluid dynamics to determine the effect of temperature on the cleaning efficiency: Higher temperatures can, to a...
Vaping is linked to a substantially increased risk of COVID-19 among teenagers and young adults, according to a new study led by researchers at the Stanford University School of Medicine.
A new study published in Nature Communications suggests by using a model of violin synchronization in a network of violin players, there are ways to drown out distractions and miscommunications that could be used as a model for human networks in society.
In severe cases of COVID-19, damage can spread beyond the lungs and into other organs, such as the heart, liver, kidney and parts of the neurological system. Beyond these specific sets of organs, however, the virus seems to lack impact. Ernesto Estrada aimed to uncover an explanation as to how it is possible for these damages to propagate selectively rather than affecting the entire body. He...
Scientists at Stockholm University have discovered that water can exhibit a similar behavior like a liquid crystal when illuminated with laser light. This effect originates by the alignment of water molecules, which exhibit a mixture of low- and high-density domains that are more or less prone to alignment. The results, reported in Physics Review Letters on the 11th of August 2020, are based on a...
Bifocal contact lenses aren't just for aging eyes anymore. In nearsighted kids as young as 7 years old, multifocal contact lenses with a heavy dose of added reading power can dramatically slow further progression of myopia, new research has found.

A combination of genetic and emotional differences may lead to post-traumatic stress (PTS) in police officers, a new study finds. Based on biological studies of officers in major cities, the study showed that the most significant PTS predictors are the tendency to startle at sudden sounds, early career displays of mental health symptoms (e.g., anxiety and depression), and certain genetic...
There are a lot of ways to try to capture grim milestone the world crossed Monday night when it recorded its 20 millionth case of COVID-19. It’s two Swedens, four Irelands, 10 Slovenias. It’s greater than the entire population of the state of New York. The outbreak that began in Wuhan, China in December 2019 has now spread to 188 countries and regions, touching every continent but...
COVID-19 response has resulted in major reductions in health facility births in Nepal and widened inequalities, with significantly increased institutional stillbirth and neonatal mortality, according to a new study.
The mechanisms that make organisms locally fit and those responsible for change are distinct and occur sequentially in evolution.
