Destroyed 'murder hornet' nest near U.S.-B.C. border contained nearly 200 queens, scientists say
When scientists in Washington state destroyed the first nest of so-called murder hornets found in the U.S., close to the border with British Columbia, they discovered about 500 live specimens in various stages of...
Dissecting colloidal glasses using laser as a lancet
Bo Li and Kai Kou, Research Fellows of IBS Center for Soft and Living Matter, together with Walter Kob, Professor of University of Montpellier and Institute Universitaire de France, and Steve Granick, Director of the IBS Center for Soft and Living Matter, report together in Nature that the onset of glass transition is a highly non-trivial process involving complex non-linear responses.
Researchers trap electrons to create elusive crystal
Like restless children posing for a family portrait, electrons won't hold still long enough to stay in any kind of fixed arrangement.
Studies detail impact of mammal species decline in Neotropics
Mammal defaunation—the loss of mammals to extinction, extirpation and population decline—in the Neotropics and its adverse effects is the focus for two scientific papers produced recently by a group of scientists led by Juliano André Bogoni, an ecologist at the University of São Paulo (USP) in Brazil. The Neotropical realm extends south from the Mexican desert into South America as far as...
Multiracial congregations in U.S. have nearly tripled, study finds
Racially diverse congregations have more than tripled in the United States over the past 20 years, and the percentage of all-white congregations has declined, according to a study by a Baylor University sociologist and two colleagues.

Smell and taste changes provide early indication of COVID-19 community spread
- ScienceDaily
- 20/11/11 21:31
Self-reports of smell and taste changes provide earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators, according to an international team of researchers. The researchers also observed a decline in self-reports of smell and taste changes as early as five days after lockdown enforcement, with faster declines reported in countries that adopted the most...
Researchers trap electrons to create elusive crystal

Now, researchers have developed a way to stack two-dimensional semiconductors and trap electrons in a repeating pattern that forms a specific and long-hypothesized crystal.
As the holiday season approaches, New York Gov. Cuomo prohibits gatherings larger than 10 people at private residences
With the holiday season approaching and COVID-19 cases on the rise, Gov. Cuomo prohibited gatherings larger than 10 people in private...
Warming May Make Hurricanes Weaken More Slowly After Landfall
In studying the effects of climate change on hurricanes, scientists have focused on what occurs over water, when storms are forming and strengthening, picking up heat and moisture as they churn over the ocean.But a new study looks at what happens after hurricanes make landfall and work their way inland. The research suggests that climate change is affecting storms during this phase of their life...
Atmospheric rivers help create massive holes in Antarctic sea ice
- ScienceDaily
- 20/11/11 20:44
Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to new research.
Robotic AI learns to be spontaneous
- ScienceDaily
- 20/11/11 20:44
Autonomous functions for robots, such as spontaneity, are highly sought after. Many control mechanisms for autonomous robots are inspired by the functions of animals, including humans. Roboticists often design robot behaviors using predefined modules and control methodologies, which makes them task-specific, limiting their flexibility. Researchers offer an alternative machine learning-based method...
Study finds lasting fatigue common after COVID-19 infection

Researchers have developed a special type of cotton face mask that kills up to 99.9999 percent of bacteria and viruses within 60 minutes of daylight exposure.
Compounds block stress-enhanced nicotine intake in rats
- ScienceDaily
- 20/11/11 20:44
Researchers have discovered that compounds that activate GABA receptors in the brain can keep rats from self-administering increased levels of nicotine during stressful conditions in an animal model for relapse.
How organ functions were shaped over the course of evolution
- ScienceDaily
- 20/11/11 20:44
A large-scale study conducted by molecular biologists has yielded groundbreaking new insights into the evolution and regulation of gene expression in mammalian organs. The scientists investigated RNA synthesis and subsequent protein synthesis in the organs of humans and other representative mammals. They were able to demonstrate that the interplay of the two synthesis processes during evolution...

Massive explosions of energy happening thousands of light-years from Earth may have left traces in our planet's biology and geology, according to new research.
Late-season Arctic research cruise reveals warm ocean temperatures, active ecosystem
- ScienceDaily
- 20/11/11 20:43
Arctic researchers have been visiting the Bering and Chukchi seas off Alaska for nearly 30 years, collecting information about the biological diversity of the watery world under the sea ice. This year, a late-season research cruise revealed a surprise. At a time of year when an ice-breaking ship is usually required to get to some of the data-gathering outposts, scientists found nothing but open...
Treatments for people with early COVID-19 infection is an urgent research focus
- ScienceDaily
- 20/11/11 20:43
COVID-19 treatments for people with early infection are needed urgently, according to experts. Treating people early in the course of infection with SARS-CoV-2, the virus that causes COVID-19, would speed their recovery, reduce the likelihood that they develop severe outcomes and reduce demand on the healthcare system, they write.
Job interest not a big predictor of job satisfaction
