National Institutes of Health officials have urged scientists to remove all references to mRNA vaccine technology from their grant applications, two researchers said, in a move that signaled the agency might abandon a promising field of medical research.

How does a robot perform as a boss at work? The results of research by Polish scientists published in Cognition, Technology & Work suggest that while robots can command obedience, it is not as strong as in the case of humans. The level of obedience towards them is generally lower than towards human authority figures, and work efficiency under the supervision of a robot is lower. For employers and HR departments, this means the need to take the psychological aspects of implementing robots in the work environment into account - their perception as an authority figure, trust in them, and potential resistance to following orders, says Konrad Maj, PhD, from SWPS University, a psychologist and head of the HumanTech Center for Social and Technological Innovation.

Whether excited about gaining new followers or desperate to win back lost subscribers, investors who saw changes to their subscriber count performed worse than before their subscribers changed, according to a new study.

• Researchers designed a gene-editing system that replaced up to a quarter of the main type of cell in the mouse liver with edited cells.
• The technique shows promise for treating genetic diseases that require the correction or replacement of defective genes in the liver.

Researchers shocked to see that bacteria’s antimicrobial resistance is strengthened when exposed to plastic particles and point to a potential outsized impact on refugees

Concentrations of lead in the air remain substantial in developed and developing countries, largely the result of industrial emissions. Even with the decline in lead in gasoline, developed countries, including the United States, still have substantial air lead emissions and in part as a result, blood lead levels in children are high worldwide.

In a new study, researchers used data on lead emissions in the air to estimate the effects of air lead concentration on infant mortality. The study found a statistically significant relation between air lead concentration and infant mortality.

A team of scientists at the Indiana University School of Medicine has identified that an eye condition affecting the retina, the light-sensing tissue in the back of the eye, may serve as an early indicator for Alzheimer's disease. Their findings, published in Alzheimer's & Dementia, offer new insights into the potential use of retinal changes as early biomarkers for Alzheimer's, which could improve diagnosis and treatment of neurodegenerative disease.

Researchers showed that bioactive glass administered with gallium oxide in the laboratory can reduce cancer cells and leave noncancerous cells unharmed.
