Study reports play-based learning may positively impact a young child's acquisition of math skills compared to direct teaching.

Heart disease can directly cause brain dysfunction early on which could lead to dementia and can treble the amount of an Alzheimer's protein in the brain, say scientists.

A study of fruit flies reveals how the insects retain neural circuits for certain motor functions while their edge on other functions declines as a result of aging.

Spending time in nature helps reduce negative feelings about body image and anxiety.

Direct transmission of BPA from a pregnant woman to her child via the placenta may have a negative impact on fetal brain development, researchers report.

Twisted nanoscale semiconductors manipulate light in a new way, researchers at the University of Bath and the University of Michigan have shown. The effect could be harnessed to accelerate the discovery and development o...

The Perseverance Mars rover is awaiting orders after its sampling apparatus became clogged by pebble-size debris.

A computational biologist is reporting that the tuberculosis vaccine, which could be associated with a reduced number and/or severity of COVID-19 cases, could assist future COVID-19 vaccine development.

Regularly eating a small serving of dried goji berries may provide protection against age-related macular degeneration, the leading cause of vision loss in seniors.

The human immune system, that marvel of complexity, subtlety, and sophistication, includes a billion-year-old family of proteins used by bacteria to defend themselves against viruses, scientists have discovered.

Data indicate that pregnant women with COVID-19 had an increased risk for stillbirth when the Delta variant of the SARS-CoV-2 virus was the dominant strain in the United States. Researchers identified the Delta variant i...

Other factors, including genetics, also influence one's chance of developing multiple sclerosis.

A new animation of Earth shows vegetation taking up and releasing carbon in sync with the seasons.

Declines in birds and mammals are hampering plants by curbing the dispersal of their seeds, in a "clear intersection of the biodiversity crisis heavily impacting the climate crisis"

Molecules containing carbon atoms, called organics, have been found all over Mars and could hypothetically have been formed by living organisms, but it seems they were not

Electrons flowing through power lines and computers inevitably encounter resistance; when they do, they lose some of their energy, which dissipates as heat. That's why laptops get hot after being used for too long and wh...

Life on Earth is made possible by our planet's magnetosphere - an invisible radiation shield that protects the surface - now it turns out that super-Earths could have magnetospheres too

MIT physicists and colleagues have discovered the "secret sauce" behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include superconductivity. Alt...

The discovery of the Higgs boson was a landmark in the history of physics. It explained something fundamental: how elementary particles that have mass get their masses. But it also marked something no less fundamental: t...

The term "endemic" usually means that an infection is stable, not that it's less deadly or that protective measures are no longer required. With the omicron variant surging, covid-19 is unlikely to become endemic soon

Indium gallium nitride (InGaN)-based, blue-light-emitting diodes are the backbone of solid-state lighting (SSL). Unfortunately, their efficiency peaks under low current densities (

A new study finds that despite increasing numbers of bald eagles, poisoning from eating dead carcasses or parts contaminated by lead shot has reduced population growth by 4% to 6% annually in the Northeast.
