Sleep disorders are associated with significantly higher rates of health care utilization including more doctors visits and prescriptions, placing an additional $94.9 billion in costs each year to the U.S. Health care system.

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome.

First came the amazing pictures, then the video. Now NASA is sharing sounds of its little helicopter humming above the surface of...

Sinopharm jab will also be added to Covax programme for the developing world in the coming weeksThe World Health Organization has given emergency use approval to one of the Chinese-made Sinopharm’s Covid-19 vaccines in a major boost to the product’s credibility.The long-awaited decision made on Friday by a WHO technical advisory group would also see the Chinese vaccine being included in the...

Deforestation of the Brazilian Amazon hit a record last month, the government reported Friday with figures that belie President Jair Bolsonaro's pledge to crack down on such destruction.

A new study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury.

China now accounts for more greenhouse gas emissions than all of the world's developed nations combined, according to new research from Rhodium Group.

Inclusion of soybean and linseed oils in the diet of dairy cows made the fatty acid content of their milk even healthier for human nutrition. It also increased the proportions of omega-6 and omega-3, which in the right balance play a key role in preventing cardiovascular diseases, for example, as well as chronic inflammation and some kinds of cancer.

Last week, China successfully launched Tianhe-1, the first part of its new space station, to be completed before the end of 2022. A week later, the mission is still making huge waves—and not in a good way. The core booster from the Long March 5B rocket that launched Tianhe-1 ended up in an uncontrolled orbit around Earth. It is expected to fall back to Earth this weekend, with current...

Researchers have traced the remaining last steps of the biological pathway that gives oats resistance to the deadly crop disease take-all.

Cicadas, red-eyed bugs singing loud sci-fi sounding songs, can seem downright creepy. Especially since the trillions of them coming this year emerge from underground only every 17 years.

For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA's Perseverance Mars rover used one of its two microphones to listen as the Ingenuity helicopter flew for the fourth time on April 30, 2021. A new video combines footage of the solar-powered helicopter taken by Perseverance's Mastcam-Z imager with audio from a microphone belonging to the...

RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven't been very useful in treating brain tumors and other brain disease. But a team has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery...

Under the cover of darkness in desert habitats about 70 million years ago, in what is today Mongolia and northern China, a gangly looking dinosaur employed excellent night vision and superb hearing to thrive as a menacing pint-sized nocturnal...

Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to characterize atomistic structures that will affect the properties and functions of the electronic devices.

An 18.5 million-year-old fossil found in Panama provides evidence of a new species and is the oldest reliable example of a climbing woody vine known as a liana from the soapberry family. The discovery sheds light on the evolution of climbing plants.

The functions of water-dominated ecosystems can be considerably influenced and changed by hydrological fluctuation. The varying states of redox-active substances are of crucial importance here. Researchers at the University of Bayreuth have discovered this, in cooperation with partners from the Universities of Tübingen and Bristol and the Helmholtz Centre for Environmental Research,...

To infect its host plant maize, the fungal parasite Ustilago maydis uses a complex of seven proteins. Numerous findings reveal an essential role of the complex in causing disease and suggest a widespread occurence in fungal plant pathogens.

Images of bare, naked white coral reefs have been increasingly circulating around the world. The typically colorful reefs of tropical oceans, which are home to many species of the marine ecosystem, are suffering from rising water temperatures due to global warming. There is no heat relief for the corals in sight. Scientists are desperately seeking out ways to make the temperature-sensitive...

Narrow-gap semiconductors with the ability to use visible light have garnered significant interest thanks to their versatility. Now, scientists in Japan have developed and characterized a new semiconductor material for application in process components stimulated by light. The findings have, for the first time, suggested a new way to reduce the band gap in cheaper and non-toxic tin-based oxide...

China says the upper stage of its Long March 5B rocket that launched the core module of its space station will mostly burn up on re-entry, posing little threat to people and property on the...

India has been added to the UK’s ‘red list’ for travel, with fears over a new variant influencing the decisionCoronavirus – latest updatesSee all our coronavirus coverageIndia has been put on the UK’s “red list” for travel as it battles a devastating rise in infections and new variants of coronavirus that have spread to other countries, including the UK. One of these variants is...

The world's largest terrestrial conservation area is located in southern Africa and covers 520,000 square kilometers spanning five countries. A study now shows that the endangered African wild dog mostly remains within the boundaries of the Kavango-Zambezi Transfrontier Conservation Area (KAZA) when dispersing, thus highlighting the relevance of such a large-scale conservation initiative for...
