Temperatures of minus 196 degrees Celsius enable high-resolution imaging of the cell's interior. Researchers at the Institute of Science and Technology (IST) Austria are thus able to show for the first time how the active form of a protein complex plays critical roles in cell motility and other important biological functions look like. This study is published in the journal Nature Communications.

An important new finding by University of Cincinnati researchers could help slow the transmission of HIV/AIDS and reduce pregnancies among adolescent girls in rural South Africa.

Even before the COVID-19 pandemic, tens of millions of children worldwide were not receiving basic doses of vaccines. New research finds there continue to be significant disparities in childhood vaccination, and poorer children from under-represented and minority groups in most countries are more likely to be less fully vaccinated with all the recommended immunizations. A special supplement to the...

Competition for mates leads to a deeper voice than expected based on size

Understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment. Now, researchers demonstrate that a commercial hand-held particle counter can be used for this purpose and help determine the impacts of risk-reducing measures, like ventilation improvements....

A team of ETH researchers led by Karsten Weis has developed a method that allows them to study the assembly process for large protein complexes in detail for the first time. As their case study, the biologists chose one of the largest cellular complexes: the nuclear pore complex in yeast cells.

The roundworm C. elegans matches its development to the amount of food in its environment. It uses a protein called BLMP-1 to open up a large set of developmental genes, priming them to turn on when food is plentiful. Humans have a protein with a similar function that is known to be overactive in some blood cancers.

Black children are removed from their families at much greater rates than any other race or ethnicity in this country. At the same time the sheer number of all child abuse investigations in the US is staggering: experts estimate that by age 18 one out of three children has been the subject of a child protective services investigation. Yet, many of these investigations and removals are unjustified,...

The more chaotic things get, the harder it is for people with clinical anxiety and/or depression to make sound decisions and to learn from their mistakes. On a positive note, overly anxious and depressed people's judgment can improve if they focus on what they get right, instead of what they get wrong, suggests a new University of California, Berkeley, study.

Substances present in cooked meats are associated with increased wheezing in children, Mount Sinai researchers report.

Can you imagine a world powered by 100% renewable electricity and fuels? It may seem fantasy, but a collaborative team of scientists has just shown this dream is theoretically possible - if we can garner global buy-in. The study explores what changes are needed in our energy mix and consumption patterns if we are to achieve 100% renewability in a way that supports everyone and the myriad of life...

A team of Northwestern University engineers is using ideas taken from paper-folding practices to create a sophisticated alternative to 3D printing.

A new study examines whether conspicuous colours of superb fairy-wrens signal male quality.

Researchers from Rice University and Baylor College of Medicine have shown that colored light can both activate and deactivate genes of gut bacteria in the intestines of worms. The research shows how optogenetic technology can be used to investigate the health impacts of gut bacteria.

A paint-on, transparent bandage containing phosphorescent materials reads the amount of oxygen reaching transplanted tissue -- a critical component of a transplant's success. Existing oximeter technology is complicated to use, restricts patients' movements, and is subject to false alarms. The first human trial of the liquid bandage in women undergoing breast reconstruction after cancer found that...

A new experiment provides better understanding of fundamental photo-induced processes with special importance for photocatalysis, photosynthesis and radiation damage

Wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing. In Physics of Fluids, researchers tested how different types of mask impacted the spread of droplets that carry the coronavirus when we cough or sneeze. Every material tested dramatically reduced the number of droplets that were spread. But at distances of less than 6 feet, enough droplets to potentially...

Researchers at the Kobe University Graduate School of Medicine have revealed that alterations in fetal microglia resulting from maternal inflammation could contribute towards the onset of developmental and psychiatric disorders. These results can help clarify how changes in microglial process motility affect the development of the neural network, thus contributing towards the treatment of these...

Patients with COVID-19 who received care at Mayo Clinic, whether in the hospital or at home, had outcomes that compared favorably to those reported nationally and internationally. These results demonstrate the value of an integrated, team-based approach to patient care and monitoring, according to a retrospective study of all patients with COVID-19 treated at Mayo Clinic March 1-July 31.

By drawing from decades of studies, scientists created a timeline marking the arrival of black-legged ticks, also known as deer ticks, in hundreds of counties across 10 Midwestern states. They used these data - along with an analysis of county-level landscape features associated with the spread of ticks - to build a model that can predict where ticks are likely to appear in future years.

Researchers at the Sainsbury Wellcome Centre have devised a brain machine interface (BMI) that allows mice to learn to guide a cursor using only their brain activity. By monitoring this mouse-controlled mouse moving to a target location to receive a reward, the researchers were able to study how the brain represents intentional control.

A team of scientists from Siberian Federal University together with their colleagues from Novosibirsk studied the effect of nanoparticles on oil production efficiency. When added to the water that displaces oil from a reservoir, nanoparticles improve the separation of oil drops from mine rock and their washing to the surface. The work received a grant from the Russian Science Foundation, and an...

Scientists have shown that adding an experimental cancer drug to a widely used diabetes treatment improves blood glucose control and weight loss in mice, according to a study published today in eLife.

Blocking gene expression in mitochondria in mice stops cancer cells from growing
