Older women who eat more than one to two servings a week of baked or broiled fish or shellfish may consume enough omega-3 fatty acids to counteract the effects of air pollution on the brain, according to a new study.

A new study has dissected how radiotherapy alters the behavior of immune cells known as macrophages found in glioblastoma (GBM) tumors and shown how these cells might be reprogrammed with an existing drug to suppress the...

Researchers have developed a new drug that prevents blood clots without causing an increased risk of bleeding, a common side effect of all antiplatelet medications currently available. A new study describes the drug and ...

A new proof-of-concept study reports evidence that a new testing method has the potential to rapidly identify radiation sickness based on biomarkers measured through a single drop of blood. Scientists say the test could ...

Biomolecular engineers have developed new tools to increase the accuracy of CRISPR single-base editing to treat genetic diseases.

With widespread, sustained declines in fertility, the world population will likely peak in 2064 at around 9.7 billion, and then decline to about 8.8 billion by 2100 -- about 2 billion lower than some previous estimates, ...

Researchers have found that combining a Western-style high-fat diet with antibiotic use significantly increases the risk of developing pre- inflammatory bowel disease. This combination shuts down the mitochondria in cell...

Researchers have discovered how diverse forms of life are able to use the same cellular machinery for DNA transcription.

Researchers have shown that an enzyme called RNA polymerase (Pol) II drives generation of the building blocks of ribosomes, the molecular machines that manufacture all proteins in cells based on the genetic code.

Researchers have developed a credit-card sized tool for growing cancer cells outside the human body, which they believe will enhance their understanding of breast cancer metastasis. The device reproduces various environm...

While 93 percent of U.S. pediatricians surveyed were aware of the national guidelines on peanut allergy prevention in infants, only 30 percent were fully implementing the recommended practices and 64 percent reported par...

Researchers have found that exposure to flaring -- the burning off of excess natural gas -- at oil and gas production sites is associated with 50% higher odds of preterm birth, compared with no exposure.

Examining the association between eight different types of early life stress (ELS) and youth-onset depression, a study reports that individuals exposed to ELS were more likely to develop a major depressive disorder (MDD)...

Meditation was linked to lower cardiovascular risk in a large database study. The team looked at data on more than 61,000 survey participants.

Two daily fasting diets, also known as time-restricted feeding diets, are effective for weight loss, according to a new study. The study reported results from a clinical trial that compared a 4-hour time-restricted feedi...

Researchers have developed a surface coating that, when painted on common objects, inactivates SARS-CoV-2, the virus that causes COVID-19.

Metabolic syndrome increases the risk of severe disease from viral infection, according to a new review.

A new review encourages researchers studying metabolism and immunity to turn their attention to ketone bodies, which are being widely studied for their role in aging, as a possible therapeutic against COVID-19, seasonal ...

Researchers studied over 2,000 critically ill adults with COVID-19, and found that 35 percent of patients died in the 28 days after ICU admission. They also found that treatment and outcomes varied greatly between hospit...

A new robotic prosthetic leg prototype offers a more natural gait while also being quieter and more energy efficient than other designs.

In a groundbreaking new study, researchers have 3D printed a functioning centimeter-scale human heart pump in the lab. The discovery could have major implications for studying heart disease, the leading cause of death in...

A common drug, already approved by the Food and Drug Administration (FDA), may also be a powerful tool in fighting COVID-19, according to new research.
