In a phase 1 clinical trial to evaluate the safety of the approach, UChicago Medicine researchers found that high-powered, tightly-targeted radiation therapy is safe for treating patients with multiple metastases.

Employees' cafeteria purchases--both healthy and unhealthy foods--were influenced by their co-workers' food choices, found a large, two-year study of hospital employees. The study made innovative use of cash register data to gain insights into how individuals' social networks shape their health behavior. The research suggests we might structure future efforts aimed at improving population health by capitalizing on how one person's behavior influences another.

What The Study Did: Researchers investigated racial/ethnic representation in clinical trials that led to U.S. Food and Drug Administration approval of ophthalmology drugs from 2000 to 2020.

What The Study Did: Claims data were used to look at opioid use among young people (ages 10 to 21) who had been prescribed opioids for the first time.

What The Study Did: This review of 125 U.S.-based clinical trials that investigated the management of hearing loss assessed representation in the trials by race/ethnicity and sex.

What The Study Did: This cohort study examines viral dynamics and transmission of infection for NBA players, staff and vendors who had clinically recovered from SARS-CoV-2 infection but continued to have positive test results following discontinuation of isolation precautions.

What The Study Did: This study assesses the association between COVID-19 and maternal and neonatal outcomes in pregnant women with COVID-19 diagnosis compared with pregnant women without COVID-19 diagnosis.

What The Study Did: This case series reports the risk factors, incidence rate and features of acute ischemic stroke experienced by a group of male patients ages 50 years or younger in the convalescent stage of COVID-19.

Stars spin faster than expected as they age according to a new study led by scientists at the University of Birmingham which uses asteroseismology to shed new light on this emerging theory.

As politics grows increasingly polarized, a new global study finds people often exaggerate political differences and negative feelings of those on the opposite side of the political divide, and this misperception can be reduced by informing them of the other side's true feelings. The study replicates earlier research in the United States, finding the phenomenon to be generalizable across 25 countries.

Soldiers, athletes, and motorists could lead safer lives thanks to a new process that could lead to more efficient and re-useable protection from shock and impact, explosion, and vibration, according to a new study.

Researchers at Albert Einstein College of Medicine have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them. The study was published online today in the journal Cell.

Using nearly a year of anonymous geolocation data from 15-17 million cell phone users in 3,037 United States counties, investigators have found that individuals with lower income per capita or greater Republican orientation were associated with significantly reduced social distancing throughout the study period from March 2020 through January 2021. Their findings are reported in the American Journal of Preventive Medicine, published by Elsevier.

The use of a novel esophagus-sparing technique reduces the rate of severe inflammation of the esophagus in patients with localized lung cancer receiving high-dose radiation and concurrent chemotherapy. Severe esophagitis was reduced despite tumors located within 1 centimeter of the esophagus, with no increased risk in local tumor recurrence.

Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers at Empa and ETH Zurich are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale.

In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets.In a new paper, two astrophysicists suggest dark matter could be detected by measuring the effect it has on the temperature of exoplanets, which are planets outside our solar system.

International team of researchers identifies cognitive computations underlying human predictive behaviour.

Two new cases helped scientists confirm what many have come to suspect: that people can get infected by SARS-CoV-2 variants even after successful vaccination. The findings suggest continued testing may be needed to prevent future outbreaks in a post-vaccine world.

Researchers at Gladstone Institutes, UC San Francisco, and UC Berkeley have developed a more efficient method than ever before to simultaneously map the specialized diversity and spatial location of individual cells within a tissue or a tumor. The technique, called XYZeq, was described online this week in the journal Science Advances. This offers new insight into the organization of tissues and the interplay between different cell types during disease, including in cancers.

For corn, using dairy manure and legume cover crops in crop rotations can reduce the need for inorganic nitrogen fertilizer and protect water quality, but these practices also can contribute to emissions of nitrous oxide -- a potent greenhouse gas.
