The first behavioral observations of wrinkle-faced bats in their natural habitat reveal that this elusive species uses the rarest form of bat courtship behavior, according to a new study.

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...
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.
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.
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...
More than half of people with acute COVID-19 infection continue to have persistent fatigue 10 weeks after their initial illness, according to a new study.
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.
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.
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.
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...
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.
Interest in an occupation matters, but not as much as you might think when it comes to job satisfaction. While it's not a strong predictor of satisfaction, a researcher found that it may help in your performance on the job.
A new study shows proteins that presumably evolved to avoid water as they fold may actually behave in ways scientists did not anticipate.
Arguably, almost all truly intriguing systems are ones that are far away from equilibrium -- such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn't be analyzed with conventional thermodynamics and statistical physics.
Researchers say that cascaded organic Rankine cycle systems could improve the way in which environmentally-friendly power is generated from waste heat.
Researchers have discovered a protein that helps protect hosts from infection with the tick-borne spirochete that causes Lyme Disease, a finding that may help diagnose and treat this infection.
A new study found that suicide rates increase during all types of disasters -- including severe storms, floods, hurricanes and ice storms -- with the largest overall increase occurring two years after a disaster. A team of researchers examined the impact of 281 natural disasters on suicide rates during a 12-year span and found overall suicide rates increased by 23% when compared to rates before...
The tongue helps people taste food, but structures on its surface also help them sense textures -- something that's also very important when savoring a meal. Now, researchers have made a 3D silicone surface that, for the first time, closely mimics the surface features of the human tongue. The material could help food scientists study mechanical interactions of foods, liquids and medicines with the...
Securing plant production is a global task. Using a combination of new molecular and statistical methods, a research team was able to show that material from gene banks can be used to improve traits in the maize plant. Old varieties can thus help to breed new varieties adapted to current and future climates.
Both of Andrew Kiselica's grandfathers developed dementia when he was in graduate school.
Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble signals detectable with quantum sensor networks such as the atomic clocks of the GPS network or the magnetometers of the GNOME network. These results are particularly interesting in the context of the search...
New research examines 459 plant natural products that met rigorous criteria for demonstrating antibacterial activity.
The understanding of unconventional superconductivity is one of the most challenging and fascinating tasks of solid-state physics. Different classes of unconventional superconductors share that superconductivity emerges near a magnetic phase despite the underlying physics is different.
Theoretical physicists have modeled the motion of microscopic, motile bodies - either powered micro-machines or living cells - in viscous liquid drops, using the Navier-Stokes equations. This work has applications in materials science and medicine.
