Novel method to fine tune 'twistronics'

Researchers have revealed a breakthrough method that could lead to autonomous robotic control and therefore precise fine tuning of the 'twist' between atom-thin 2D materials layers stacked in a superlattice structure -- a pioneering device that could help transform technology and achieve superconductive electronics.

The climate changed rapidly alongside sea ice decline in the north

Researchers have shown that abrupt climate change occurred as a result of widespread decrease of sea ice. This scientific breakthrough concludes a long-lasting debate on the mechanisms causing abrupt climate change during the glacial period. It also documents that the cause of the swiftness and extent of sudden climate change must be found in the oceans.

Protein storytelling to address the pandemic

Computer molecular physics has contributed to the understanding of protein behavior by creating 3D models of molecular machines and setting them in motion. Researchers at Stony Brook University are using the Frontera supercomputer at the Texas Advanced Computing Center to make structure predictions for 19 proteins from the SARS-CoV-2 virus about which little is known. Their team uses a method they...

Ionic defect landscape in perovskite solar cells revealed

Researchers have uncovered the ionic defect landscape in metal halide perovskites. They were able to identify essential properties of the ions that make up these materials. The migration of the ions leads to the presence of defects in the material, which have a negative effect on the efficiency and stability of perovskite solar cells.

Findings about cilia on cells of the vessel wall may be relevant for diabetes treatment

A new study shows that primary cilia, hair-like protrusions on endothelial cells inside vessels, play an important role in the blood supply and delivery of glucose to the insulin-producing beta cells in the pancreatic islets. The findings may be relevant for transplantation therapies in diabetes, as formation of functional blood vessels is important for the treatment to be successful.

Biological diversity evokes happiness

A high biodiversity in our vicinity is as important for life satisfaction as our income, scientists found. All across Europe, the individual enjoyment of life correlates with the number of surrounding bird species. An additional 10% of bird species therefore increases the Europeans' life satisfaction as much as a comparable increase in income. Nature conservation thus constitutes an investment in...

How bean plants fend off famished foes

Scientists have discovered that cowpeas -- a type of bean plant -- harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore defenses.

Strategies for boosting accuracy of personal genetic risk scores

As the consumer genetics industry rapidly expands, more and more people are turning to DNA-based services to learn their risk of developing a wide range of diseases. However, the risk scores from these genetic tests are not always as precise as they could be, according to a new study. The scientists examine many approaches to calculating the scores and recommend that personal genomics...
