SARS-CoV-2 genomic recombination is uncommon but disproportionately occurs in spike protein region

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to attach to and infect host cells.

Bird behavior influenced by human activity during COVID-19 lockdowns

For humans, the early days of the COVID-19 pandemic were a stressful time, marked by fear, isolation, canceled plans and uncertainty. But for birds that inhabit developed areas of the Pacific Northwest, the reduction in noise and commotion from pandemic lockdowns may have allowed them to use a wider range of habitats in cities.

Stampede2 supercomputer simulates star seeding, heating effects of primordial black holes

Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes.

Newly identified fossil insect used 360-degree vision and sticky feet to find and snare its meals

With bulging eyes, an elongated mouth and feet that oozed resin, a fossil insect identified by Oregon State University research is so different from anything alive today that it needed to be placed in its own, extinct family.

400 million voting records show persistent gaps in voter turnout by race, age, and political affiliation

A new study from BYU and the University of Virginia analyzed 400 million voter records from elections in 2014 and 2016 and found that minority citizens, young people, and those who support the Democratic Party are much less likely to vote than whites, older citizens, and Republican Party supporters. Moreover, those in the former groups were also more likely to live i

Study demonstrates combination of betadine and silver colloidal gel effectively eliminates infection-causing bacteria

Findings from a new study published today in the American Journal of Infection Control (AJIC) suggest that a combination of betadine and silver colloidal gel are more effective than either material alone for inhibiting the growth of common infection-causing bacteria. The findings could help medical professionals better treat and prevent serious infection

Looking for 'ever-loving homes': Nearly 4,000 beagles bred for drug experiments rescued

In what's thought to be one of the biggest dog rescue efforts in the U.S., nearly 4,000 beagles are looking for forever homes after being saved from a Virginia facility that bred them to be sold to laboratories for drug experiments.

Nearly a hundred genes have been lost during the woolly mammoth's evolution

A new study shows that 87 genes have been affected by deletions or short insertions during the course of the mammoth's evolution. The researchers note that their findings have implications for international efforts to resurrect extinct species, including the woolly mammoth. The study was published today in the journal iScience by researchers at the Centre for Palaeogenetics in Stockholm, a colla

New study reveals computation-guided approach to suppressing cancer tumor growth

A new study, led by researchers from the University of California, Irvine and the University of California, San Diego, reveals a new computation-guided approach to identify small molecules that can restore aspects of wild-type p53 tumor suppression function to mutated p53, which play an important role in many human cancers. This approach was successful both in vitro and in vivo. This strate

Scientists identify mechanism crucial for COVID-19 virus replication

A team led by UT Southwestern researchers has identified how SARS-CoV-2, the virus that causes COVID-19, builds a structure called the RNA cap that's critical for successful viral replication. The finding, published in Nature, could lead to new strategies to attack COVID-19, which has sickened nearly 600 million and killed more than 6 million worldwide thus far.

New research reveals the circadian clock influences cell growth, metabolism and tumor progression

In a new University of California, Irvine-led study, researchers define how the circadian clock influences cell growth, metabolism and tumor progression. Their research also reveals how disruption of the circadian clock impacts genome stability and mutations that can further drive critical tumor-promoting pathways in the intestine.
