Expression of 'fat' genes correlate with metabolic, behavioral changes linked to obesity

Eurekalert - Jun 03 2021 - 00:06
A collection of genetic variants influences the expression of obesity-associated genes in both the brain and fat tissue, according to a new study from researchers at the University of Chicago.

Mixed farming methods could reduce US emissions and increase productivity

Eurekalert - Jun 03 2021 - 00:06
Small-scale mixed-use agriculture that avoids synthetic fertilizers in favor of manure could eliminate agricultural greenhouse gas emissions if established across the United States' 100 million hectares of lush high quality cropland, according to a study by Gidon Eshel, publishing 3rd June 2021 in the open-access journal PLOS Biology. The minor catch: beef consumption would need to decrease, but by only 20%.

Surveillance for endemic respiratory viruses needed to understand post-COVID-19 circulation

Eurekalert - Jun 03 2021 - 00:06
The widespread non-pharmaceutical interventions implemented to mitigate the transmission of COVID-19 have led to drastic reductions in the annual circulation patterns of other endemic respiratory viruses, including influenza and the common cold.

Passing the acid test: New, low-pH system recycles more carbon into valuable products

Eurekalert - Jun 03 2021 - 00:06
An engineering researcher from the University of Sydney, in collaboration with a team at the University of Toronto, has developed an electrochemical system that coverts a greater amount of CO2 into valuable products, such as ethylene and ethanol. These are used in everyday materials, from plastic to Lycra.

Healing hydrogels

Eurekalert - Jun 03 2021 - 00:06
Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly recover from mechanical stress. This opens up the use of such biocompatible materials in the field of artificial joints and ligaments.

First cells reprogrammed to make synthetic polymers; also making them resistant to viruses

Eurekalert - Jun 03 2021 - 00:06
Scientists have developed the first cells that can construct artificial polymers from building blocks that are not found in nature, by following instructions the researchers encoded in their genes. The study, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology, in Cambridge, UK, also found the synthetic genome made the bacteria entirely resistant to infection by viruses.

A shark mystery millions of years in the making

Eurekalert - Jun 03 2021 - 00:06
The biggest shark attack in history did not involve humans.A new study by Earth scientists from Yale and the College of the Atlantic has turned up a massive die-off of sharks roughly 19 million years ago. It came at a period in history when there were more than 10 times more sharks patrolling the world's oceans than there are today.

Front-row view reveals exceptional cosmic explosion

Eurekalert - Jun 03 2021 - 00:06
Scientists have gained the best view yet of the brightest explosions in the universe: A specialised observatory in Namibia has recorded the most energetic radiation and longest gamma-ray afterglow of a so-called gamma-ray burst to date. The observations with the High Energy Stereoscopic System (H.E.S.S.) challenge the idea of how gamma-rays are produced in these colossal stellar explosions which are the birth cries of black holes, as the international team reports in the journal Science.

Life stage differences shield ecological communities from collapse

Eurekalert - Jun 03 2021 - 00:06
A new study by ecologist André de Roos shows that differences between juveniles and adults of the same species are crucial for the stability of complex ecological communities. The research, published in Proceedings of the National Academy of Sciences, represents a major advance in ecological modeling at a time when biodiversity is declining and species around the world are rapidly going extinct.

Polar vortex, winter heat may change bird populations

Eurekalert - Jun 03 2021 - 00:06
Researchers set out to learn how extreme winter cold and heat affected 41 common bird species in eastern North America. They found that individual bird species respond differently to these weather events, and extreme winter heat may lead to longer-term changes in bird populations.
