South Pole and East Antarctica warmer than previously thought during last ice age, two studies show
University of Washington glaciologists are co-authors on two papers that analyzed Antarctic ice cores to understand the continent's air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition.

Scientists discover new approach to stabilize cathode materials
UPTON, NY--A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings, published in Nature Communications, demonstrated that the valence gradient can serve as a new approach for stabilizing the structure of high-nickel-content cathodes against degradation and safety issues.

Shoot better drone videos with a single word
A team from Carnegie Mellon University, the University of Sao Paulo and Facebook AI Research developed a model that enables a drone to shoot a video based on a desired emotion or viewer reaction. The drone uses camera angles, speeds and flight paths to generate a video that could be exciting, calm, enjoyable or nerve-wracking -- depending on what the filmmaker tells it.

Immune therapy after surgery lowers relapse risk in patients with high-risk melanoma
Patients with high-risk melanoma who had a course of pembrolizumab after their surgery had a longer time before their disease recurred than patients who got either ipilimumab or high-dose interferon after surgery. These findings of a large SWOG Cancer Research Network clinical trial, S1404, will be presented at the ASCO annual meeting June 6, 2021.

Study on heavy drinking in young adults and the psychological impacts of COVID-19
In a sample of nearly 500 young adults ranging in age from 18 to 25, researchers saw a reduction in problematic drinking and alcohol consequences during the initial phase of the pandemic for both men and women. Additional findings showed increased rates of depression and anxiety symptoms among young women.

New method accurately reflects hotspots in epidemic
A new method to monitor epidemics like COVID-19 gives an accurate real-time estimate of the growth rate of an epidemic by carefully evaluating the relationship between the amount of viruses in infected people's bodies, called the viral load, and how fast the number of cases is increasing or decreasing.

Studies reveal skull as unexpected source of brain immunity
Researchers at Washington University School of Medicine in St. Louis have discovered that the immune cells that protect the brain and spinal cord come primarily from the skull. The finding opens up the possibility of developing therapies to target such cells as a way to prevent or treat brain conditions.

Mixed farming methods could reduce US emissions and increase productivity
Small-scale mixed-use agriculture that avoids synthetic fertilizers in favor of manure could eliminate agricultural greenhouse gas emissions if established across the United States' 100 million hectares of lush high quality cropland, according to a study by Gidon Eshel, publishing 3rd June 2021 in the open-access journal PLOS Biology. The minor catch: beef consumption would need to decrease, but by only 20%.

Surveillance for endemic respiratory viruses needed to understand post-COVID-19 circulation
The widespread non-pharmaceutical interventions implemented to mitigate the transmission of COVID-19 have led to drastic reductions in the annual circulation patterns of other endemic respiratory viruses, including influenza and the common cold.
