'Natural disasters' increase triggers for violence against women and girls
'Natural disasters,' sparked by climate change and other natural hazards, increase the triggers for violence against women and girls by boosting the means, opportunity, and underlying drivers, finds a review of the available evidence, published in the online journal BMJ Global Health.As these disasters are increasing in frequency, severity, and duration worldwide, this consequence must now be formally recognised in public health, violence prevention, and disaster management strategies, urge the researchers.

Hollings researchers study SARS-CoV-2 antibodies in asymptomatic & symptomatic individuals
MUSC Hollings Cancer Center researchers screened more than 60,000 blood samples from symptomless individuals in the Southeastern U.S., finding that approximately 3% of the population is asymptomatic. These individuals had stronger antibody responses to COVID-19 versus symptomatic patients.

'Molecular glue' makes perovskite solar cells dramatically more reliable over time
In a study that could help to bring inexpensive, efficient perovskite solar cells one step closer to commercial use, researchers found a way to strengthen a key weak point in the cells' internal structure, dramatically increasing their functional life.

Review: Most human origins stories are not compatible with known fossils
In the 150 years since Charles Darwin speculated that humans originated in Africa, the number of species in the human family tree has exploded, but so has the level of dispute concerning early human evolution. A new review looks at the major discoveries in hominin origins since Darwin's works and argues that fossil apes can inform us about essential aspects of ape and human evolution, including the nature of our last common ancestor.

Evading the uncertainty principle in quantum physics
In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both be known fully precisely at the same time. In a study published this week in Science, researchers show that two vibrating drumheads, the size of a human hair, can be prepared in a quantum state which evades the uncertainty principle for the first time.

What can a dinosaur's inner ear tell us? Just listen
New Haven, Conn. -- If paleontologists had a wish list, it would almost certainly include insights into two particular phenomena: how dinosaurs interacted with each other and how they began to fly.

Dinosaurs that hunted in the dark
A new study led by Wits University scientist, Professor Jonah Choiniere, used CT scanning and detailed measurements of the relative size of the eyes and inner ears of nearly 100 living bird and extinct dinosaur species, to investigate how the sensory adaptations of these two groups compared. The team found that a diminutive theropod named Shuvuuia, had extraordinary hearing and night vision, suggesting that Shuvuuia could have hunted in complete darkness.

Protected by nanobrushes
The ability of antibodies to recognize specific cancer cells is used in oncology to specifically target those cells with small active agents. Research published in the journal Angewandte Chemie shows that scientists have now built a transport system that delivers even large protein-based drugs into cancer cells. This study demonstrates how proteins can arrive at their target intact, protected from destructive proteases by polymer brushes.

Ice core data show why, despite lower sulfur emissions in US and Western Europe, air pollution is
Ice core data from Greenland shows why air pollution is reducing slower than sulfur emissions reductions. As cloud droplets become less acidic, the chemical reaction that turns sulfur dioxide into sulfate aerosol gets more efficient. These results can improve the models that project air quality and climate change.

Asthma attacks plummeted among Black and hispanic/latinx individuals during the COVID-19 pandemic
Asthma attacks account for almost 50 percent of the cost of asthma care which totals $80 billion each year in the United States. Asthma is more severe in Black and Hispanic/Latinx patients, with double the rates of attacks and hospitalizations as the general population.

Healthy young adults who had COVID-19 may have long-term impact on blood vessels and heart health
New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.

Physicists describe new type of aurora
The famed northern and southern lights have been studied for millennia, but they still hold secrets. In a new study, physicists led by the University of Iowa describe a new phenomenon they call "diffuse auroral erasers," in which patches of the background glow are blotted out, then suddenly intensify and reappear.

Blocking viruses' exit strategy
The Marburg virus, a relative of Ebola, likewise causes a dangerous and often fatal disease. In a study co-led by the University of Pennsylvania's Ronald Harty, an experimental antiviral drug, which prevents the virus from exiting host cells and spreading to new cells, showed promising results. The researchers are also encouraged by similarities in the drug's response against SARS-CoV-2, the virus that causes COVID-19.
