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 invariable recurrence of the aggressive brain cancer.
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 its delivery mechanisms and shows that the drug is also an effective treatment for heart attack in animal models.
A new, 10-year study by researchers at the University of California, Davis, examined 35 dog breeds and found vulnerability from neutering, and the age at which they are neutered, varies greatly depending on the breed.
New modeling shows how social distancing could have better been implemented. The key? Longer periods of distancing would have helped -- but only to a point. More needed to be done.
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 help save lives through early and real-time identification of the condition to enable timely clinical interventions.
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, according to a new study.
A new spin on the magnetic compression of plasmas could improve materials science, nuclear fusion research, X-ray generation and laboratory astrophysics.
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 cells of the colon lining, leading to gut inflammation. Mesalazine can help restart the mitochondria and treat pre-IBD condition.
Researchers have discovered how diverse forms of life are able to use the same cellular machinery for DNA transcription.
With the right mix of plants, urban green spaces can be a rich habitat to support diverse pollinators, according to a new study.
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.
New research looks at how caregivers address the issues of firearm safety when taking care of someone who has Alzheimer's Disease and Related Dementias (ADRD) and has access to a gun.
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 environments within the human body where breast cancer cells live. Studying the cells as they go through the process of invasion and metastasis could point the way toward new biomarkers...
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 partial implementation, according to the study.
Newfound bacteria that oxidize manganese help explain the geochemistry of groundwater.
From 2010 to 2018, scientists tagged 56 tiger sharks of varying life stages to track their movements via satellite. Movement patterns varied by life stage, sex, and season. Some of their core habitats overlapped with locations designated by NOAA as Habitat Areas of Particular Concern and also were found near 2,504 oil and gas platforms. Findings may help inform studies into potential climate...
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) in childhood or adolescence than individuals who had not been exposed to ELS.
New research shows that embedding a reading-and-writing exercise about social belonging into the first-year college curriculum increased the persistence and performance of Black, Latinx, Native American, and first-generation students at a large, urban, broad-access university.
The Hyksos, who ruled during the 15th Dynasty of ancient Egypt, were not foreign invaders, but a group who rose to power from within, according to a new study.
Researchers have developed a tiny camera that can ride aboard an insect or an insect-sized robot.
Researchers have discovered three distinct immune responses to the SARS-CoV2 infection that could help predict the trajectory of disease in severe COVID-19 patients and may ultimately inform how to best treat them. A second study uncovered new details about the innate, or initial, response to SARS-CoV2.
