Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity and relativity -- this time with the help of a neutron star flashing across space.

To create large quantum networks, researchers will first need to develop efficient quantum repeaters. A key component of these repeaters are quantum memories, which are the quantum-mechanical equivalents of more conventi...

When SpaceX launched a Falcon 9 rocket into space Saturday (June 13), it delivered 58 Starlink satellites and three Planet SkySats into orbit. It also looked amazing.

Scientists have developed molecules that can remodel the bacterial population of intestines to a healthier state. They also have shown -- through experiments in mice -- that this approach reduces cholesterol levels and s...

A survey of 1,000 outdoor education programs nationwide finds that nearly two-thirds are in danger of folding because of the COVID-19 pandemic. Such programs connect youth with the world around them and teach about natur...

The complex food shopping patterns that financially insecure families employ have been upended by COVID-19. To facilitate advocacy and policy change around this food insecurity crisis, researchers developed a web mapping...

Greater adherence to a variety of healthy eating patterns was associated with a lower risk of cardiovascular disease.

Transmission of COVID-19 from mother to baby during pregnancy is uncommon, and the rate of infection is no greater when the baby is born vaginally, breastfed or allowed contact with the mother, according to a new study.

A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it.

The brain and its surrounding blood vessels exist in a close relationship. Researchers have discovered how cells of the blood vessels sense the metabolic condition of the brain and alter vascular function in response. Th...

A new study attempts to shed light on triggers of post-trauma nightmare occurrences -- a topic that has received scant study.

Researchers have established a cell culture that allows them to test antibody-laden plasma, drugs and drug combinations in the laboratory. A screen of 136 safe-in-human antiviral drugs and identified six promising candid...

Researchers have discovered antibodies in the blood of recovered COVID-19 patients that provide powerful protection against SARS-CoV-2, the coronavirus that causes the disease, when tested in animals and human cell cultu...

A new study challenges claims from some international scientific circles, that having high blood levels of folate (folic acid) increases the risk of poor cognition in older adults, especially in those with low levels of ...

If past hospitalizations for pneumonia and other respiratory illnesses are any guide, many Americans could face high out-of-pocket medical costs for COVID-19 hospitalizations.

A new paper reports on the prevalence of infections with the SARS-CoV-2 virus in women admitted to labor and delivery units in several Boston hospitals.

Researchers have found two genes that regulate the differentiation of stem cells in the small intestine, offering valuable insight into how the body develops and maintains a healthy gut.

Researchers have developed a way for laboratories to determine how accurately they can detect large mutations. The new method and the benchmark material enable researchers, clinical labs and commercial technology develop...

New research indicates some neurons can shift to process information about movement depending on the brain's current frame of reference. The findings may have implications for developing future prosthetics and for unders...

There is a clear link between improved gut microbiota and one of our most common cholesterol-lowering drug groups: statins.

The number of human tuberculosis (TB) cases that are due to transmission from animals, as opposed to human-to-human transmission, may be much higher than previously estimated, according to an international team of resear...

The Democratic Republic of the Congo is using vaccinations, contact tracing and mobile handwashing stations to combat its latest Ebola outbreak, the 11th since the virus was first discovered in 1976
