The first randomized controlled trial of its kind aimed at identifying an effective way to manage myopia was published last week.

A proposed machine learning framework and expanded use of blockchain technology could help counter the spread of fake news by allowing content creators to focus on areas where the misinformation is likely to do the most public harm, according to new re…

In a sample of nearly 3,000 older adults who took vision tests and cognitive tests during home visits, the risk of dementia was much higher among those with eyesight problems — including those who weren’t able to see well even when they were wearing t…

Earth’s oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can’t find them, and…

A newly published study describes the response to sea level rise by the silver rice rat, an endangered species only found in the Florida Keys.

In a breakthrough for bioengineering, researchers have developed organoids that can model the human respiratory tract. The organoids, called AirGels, allow them to uncover the mechanism by which antibiotic-resistant pathogens like Pseudomonas aeruginos…

An evaluation of 17 previously published studies suggests that exposure to lead in the womb or in childhood is associated with an increased risk of engaging in criminal behavior in adulthood — but more evidence is needed to strengthen understanding.

The availability, speed and effectiveness of genomic sequencing increased dramatically during the pandemic, as scientists worldwide rushed to find ways to track and predict the virus’s movement and evolution. It also was critical in the development of …

New research reveals a type of monoclonal antibody already tested in certain forms of cancer may be a promising treatment in stopping the progression of amyotrophic lateral sclerosis, or ALS, a fatal neurodegenerative disease.

The public funding of science is responsible for many of the biomedical and other scientific breakthroughs on which our lives depend. However, the process through which funding decisions are made, the peer review of grant proposals, has been historical…

In the peak heat of summer, beachgoers don’t want their plans thwarted by harmful algal blooms (HABs). But current methods to remove or kill toxin-producing algae and cyanobacteria aren’t efficient or practical for direct applications in waterways. Now…

A patch of ocean in the North Atlantic is stubbornly cooling while much of the planet warms. This anomaly — dubbed the ‘cold blob’ — has been linked to changes in ocean circulation, but a new study found changes in large-scale atmospheric patterns ma…

When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the …

Researchers have developed a device — a breath test that uses a biosensor — as a tool for use in doctors’ offices and crowded public locations to quickly diagnose people infected with the virus that causes COVID-19.

Scientists have demonstrated how mice choose between three different strategies to navigate through their surroundings towards a goal.

Engineers have developed HADAR, or heat-assisted detection and ranging.

The closure in January 2016 of one of Pittsburgh’s biggest coal-processing plants led to immediate and lasting declines in emissions of fossil fuel-related air pollutants. These in turn were linked to near-instant decreases in local heart-related emerg…

The statistical model identifies links between battles in Africa and can be applied to other armed conflicts, according to a new study.
