Bronze Age farmers gave preferential treatment to cows over domesticated sheep, goats
- ScienceDaily
- 21/8/4 20:12
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...
'Where does it hurt?' predicts chronic pain outcomes, study shows
- ScienceDaily
- 21/8/4 20:11
Pain distribution as reported on a body map, on its own, can be used to assign patients to distinct subgroups that are associated with differences in pain intensity, pain quality, pain impact and clinically-relevant three-month outcomes, according to a new study.

- ScienceDaily
- 21/8/4 18:36
A new mathematical model for predicting infectious disease outbreaks incorporates fear -- both of disease and of vaccines -- to better understand how pandemics can occur in multiple waves of infections, like those we are seeing with COVID-19.
Towards next-gen computers: Mimicking brain functions with graphene-diamond junctions
- ScienceDaily
- 21/8/4 18:36
The human brain holds the secret to our unique personalities. But did you know that it can also form the basis of highly efficient computing devices? Researchers recently showed how to do this, through graphene-diamond junctions that mimic some of the human brain's functions.
Study reveals what triggers lung damage during COVID-19
- ScienceDaily
- 21/8/4 18:36
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
- ScienceDaily
- 21/8/4 18:36
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...
Crawling important step in development of risk perception

Biochar can boost crop yields in poor soils and help stop the effects of climate change, study finds.
Physical activity jolts brain into action in the event of depression
- ScienceDaily
- 21/8/4 18:36
The dual beneficial effect of physical activity in depression is confirmed by a new study: physical activity not only reduces depressive symptoms. It also increases the brain's ability to change.
Eating more plant foods may lower heart disease risk in young adults, older women
- ScienceDaily
- 21/8/4 18:36
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
- ScienceDaily
- 21/8/4 18:36
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.
Lava lamp tectonics: Research suggests giant blobs of subducted sediment float up through deep Earth
- ScienceDaily
- 21/8/4 18:35
Sand and mud subducted off the coast of California around 75 million years ago returned to the Earth's crust by rising up through the mantle as enormous diapirs, like blobs in a lava lamp, new research shows.
Frequent consumption of peanuts by cancer patients may increase risk of cancer spread, study finds

Flexible, wearable X-ray detector doesn’t require heavy metals
- ScienceDaily
- 21/8/4 18:35
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...
