Bronze Age farmers gave preferential treatment to cows over domesticated sheep, goats

Meat and dairy played a more significant role in human diets in Bronze Age China than previously thought. A new analysis also suggests that farmers and herders tended to sheep and goats differently than they did their cows, unlike in other parts of the world -- keeping cows closer to home and feeding them the byproducts of grains that they were growing for their own consumption, like the grass...

Common weight-loss drug successfully targets fat that can endanger heart health

Researchers have announced successful results of a clinical trial for a commonly prescribed weight-loss drug called liraglutide. In adults who are overweight or have obesity combined with high cardiovascular risk, once-daily liraglutide combined with lifestyle interventions significantly lowered two types of fat that have been associated with risk to heart health: visceral fat and ectopic fat.

Study reveals what triggers lung damage during COVID-19

Researchers found that a specific subtype of macrophages that originated from blood monocytes plays a key role in the hyper-inflammatory response in SARS-CoV-2 infected lungs, by performing single-cell RNA sequencing of bronchoalveolar lavage fluid cells. This study provides new insights for understanding dynamic changes in immune responses to COVID-19.

Promoting biodiversity-friendly landscapes - beyond organic farming

Is organic farming the only alternative to conventional agriculture to promote biodiversity in agricultural landscapes? An international research team questions this. According to the authors, a landscape mosaic of natural habitats and small-scale and diverse cultivated areas is the key to promoting biodiversity on a large scale in both conventional and organic agriculture. They state that...

Eating more plant foods may lower heart disease risk in young adults, older women

Eating a plant-centered diet during young adulthood is associated with a lower risk of heart disease in middle age, according to a long-term study with about 30 years of follow-up. A separate study with about 15 years of follow-up found that eating more plant-based foods that have been shown to lower cholesterol, called the 'Portfolio Diet', is associated with lower risk of cardiovascular disease...

Study links economic mobility to racial mortality gaps

A new study suggests structural racism measured by the racial economic mobility gap between Black and White persons with a similar parental income (as an indicator of similar childhood socioeconomic status) is strongly associated with Black-White disparities in mortality in the United States, both in a recent birth cohort and in all ages combined.

Flexible, wearable X-ray detector doesn’t require heavy metals

X-ray imaging is a fast and painless way for doctors to see inside a person. But radiation detectors, which go under the body part being imaged, are rigid panels that contain harmful heavy metals, such as lead and cadmium. Now, researchers report a proof-of-concept wearable X-ray detector prepared from nontoxic metal-organic frameworks (MOFs) layered between flexible plastic and gold electrodes...

ArtSea Ink: A colorful, seaweed-based ink for 3D printing

Some artists are embracing 3D printing as a new medium, allowing them to create intricate 3D compositions that are difficult to produce in any other way. But the rigid, plastic-based materials used in many 3D printers require high heat for workability. Now, researchers reporting in ACS Omega have developed a colorful new ink for 2D and 3D art made of mica pigments in alginate, a sugar from seaweed...

Illuminating tissue formation

Researchers have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders.
