There are a few superconducting material systems for electric transmission in various stages of development. In the meantime, researchers are conducting experiments to look for superconductivity in a room-temperature and atmospheric pressure environment.

Scientists are evaluating machine-learning models using transfer learning principles.

Currently, there is little research focused on understanding mechanisms and drug discovery of lymphatic vascular diseases. However, conditions such as lymphedema, a buildup of fluid in the body when the lymph system is damaged, impact more than 200,000 people every year in the United States alone.

A new analysis outlines 150 years of sea-surface temperature history throughout the Greater Caribbean region, highlighting significant warming trends that have disrupted coral reef ecosystems.

Researchers have developed a huggable, cushion-like device that mechanically simulates breathing, and preliminary evidence suggests it could help reduce students' pre-test anxiety.

Treatments integrating music and auditory beat stimulation are effective in reducing state anxiety in some patients, according to a new study.

Low-consumption office buildings with infrequent water use could have chemical and microbiological safety issues, according to a new study. The research could have implications for office buildings used less frequently during pandemic lockdowns, and suggests that regular water testing in commercial buildings may be needed.

A new study of brain development in mice shortly after birth may provide insights into how early life events can affect wiring patterns in the brain that manifest as disease later in life.

Scientists have just identified how specific immune cells can work together in fat to cause inflammation that leads to weight gain and obesity. Their work pinpoints new avenues to exploit the regulation of that inflammation in fat tissue, thereby suggesting new ways to manage obesity.

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.

Scientists have visualized the two parts of an elusive particle -- the moiré exciton -- to reveal its structure and unique properties.

With the resurgence of interest in cancer metabolism, researchers are coming to realize that there is more to a cell's biochemistry than once thought.

Looking for techniques to keep young athletes safer post-concussion, researchers devised a study in which teenage athletes who suffered concussions were randomized either to standard of care -- typically returning to play after clearing a set of standardized protocols that assess symptoms, cognition, and balance -- or completing the same protocol and then working with an athletic trainer on a specific neuromuscular training intervention that includes guided strength exercises and a focus on posture and landing stability.

Researchers have developed a new genomic technology to simultaneously analyze the DNA, RNA and chromatin -- a combination of DNA and protein -- from a single cell. The method, which took five years to develop, is an important step forward for large collaborations where multiple teams are working simultaneously to classify thousands of new cell types. The new technology will help streamline analyses.

Computational biologists have created a neural network model capable of predicting how changes to non-coding DNA sequences in yeast affect gene expression. They also devised a unique way of representing this data in two dimensions, making it easy to understand the past and future evolution of non-coding sequences in organisms beyond yeast -- and even design custom gene expression patterns for gene therapies and industrial applications. Despite the sheer number of genes that each human cell contains... Читать дальше...

A research team elucidates how bacteria use the compound guanidine as a source of nitrogen.

While it had been assumed that unstable gliding was the key to agility in bird flight, a collaboration between aerospace engineers and biologists has revealed that stability plays a role.

The transition of human societies from hunter-gatherers to farmers and pastoralists is a more nuanced process than generally thought, according to a new study of peoples living in the highlands of southwest Ethiopia.

Researchers have identified a potential new therapy for COVID-19: a biologic substance created by reengineered human skin cells.

Dinosaurs went extinct 65 million years ago, mammoths 4,000 years ago, and the Christmas Island Rat 119 years ago. Since becoming a popular concept in the 1990s, de-extinction efforts have focused on grand animals with mythical stature, but now a team of paleogeneticists has turned their attention to Rattus macleari, and their findings provide insights into the limitations of de-extinction across all species.

Tiny cellular machines called ribosomes build proteins. When this building process goes awry in bacteria, ribosomes collide, triggering the arrival of a first responder molecule that begins a rescue operation.

Communication between quantum systems depends on their ability to effectively interact with light. Some molecular crystals have proven to be new materials with excellent quantum properties. They are of great interest for creating quantum computers that can communicate among themselves using fibre optic networks.

Chile's saltwater lake closest to lithium mining activity has lost 10 to 12 percent of its flamingo population in the past 11 years. Although climate change has caused numerous saltwater lakes in the region to shrink, the flamingo population at the other lakes has held steady. As lithium mining increases to supply the metal to electric vehicles and other products, the effect could spread, according to new research.

A new study investigates whether protecting and restoring large animal wildlife can help to support climate change goals.

Viruses are tiny but mighty intruders that can be found in the environment including in human bodies, and they can play a variety of roles in ecosystems. Viruses also come in a range of sizes. Some are even larger than bacteria, which scientists thought were rare cases until recently.
