An article address unresolved scientific questions that can help avert future lead poisoning disasters. A better-informed society can prevent such disasters from happening through improved risk assessment, anticipation and management of factors affecting lead release.

A new study simultaneously examined the preferences of community members and compared those with the community-based programs and resources available to identify the most viable strategies for addressing disparities in healthy food consumption.

A new study estimates that more than 1.15 billion breakfasts and lunches for low-income children were not served in school as a result of school closures between March 9 and May 1. States and school districts have developed innovative solutions to meet the nutritional needs of low-income children and respond to the rapidly growing food insecurity crisis, yet the number of replacement meals is likely far short of what they provided prior to the pandemic.

A new study examined the effectiveness of common household fabrics in blocking droplets. Researchers tested the breathability and droplet-blocking ability of 11 common household fabrics, using a medical mask as a benchmark. The fabrics selected ranged from new and used garments, quilted cloths, bedsheets and dishcloth material.

Study shows that short, easy-to-apply relaxation techniques can activate the body's regenerative system for fighting stress -- offering new perspective on how we can treat stress-related disease

Drugs tackling chronic myelogenous leukemia have completely transformed prognoses of patients over the last couple of decades, with most cases going into remission. But drug resistance can occur, leading to relapses. Targeting the lipids involved in regulating part of a leukemia stem cell's life span offers a potential second route to defeat the disease -- and solid tumorous cancers as well.

Based on highly sensitive recordings of neuron activity in the noses of mice, researchers have found that olfactory sensory neurons can exhibit suppression or enhancement of response when odors are mixed, overturning a long-standing view that the response is a simple sum with more complex processing only happening at later stages.

Based on reported cases, Unverricht-Lundborg disease, also known as progressive myoclonic epilepsy-1A, EPM1, is more common in Finland than anywhere else in the world, a new study finds.

In March, researchers began to develop a new, low-cost, CRISPR-based diagnostic platform to detect infectious diseases, including HIV virus, the novel coronavirus (SARS-CoV-2). Today, the method is one step closer to being a cutting-edge diagnostics technology for rapid detection of infectious diseases.

A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research has found.

Scientists have identified a new area of the brain that could be involved in cost-benefit decision-making.

A 90-minute COVID-19 test has been shown to have over 94 percent sensitivity, and 100 percent specificity in a new study.

Researchers report that Chinese workers are highly aware of, and informed about, COVID-19 but there is still a need for strengthening this knowledge, and health interventions, among older and less-educated workers.

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made and dismantled. The study could also help us understand how different mammals evolved from one another and help refine methods for regenerative medicine.
