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.

Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia's Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.

Study examines neighborhood and social network relation to adult binge drinking.

Researchers with the University of Florida have developed a novel method for priming the immune system to fight salmonella infection.

This new form of regulation highlights its potential involvement in fundamental cellular processes that require profound changes in gene expression programmes, such as cell differentiation or reprogramming, as well as tumour transformation and progression.

After the most comprehensive review to date, a panel of leading medical experts conclude that ivermectin should be systematically and globally adopted for the prevention and treatment of COVID-19.

Induced bank filtration is a key and well-established approach to provide drinking water supply to populated areas located along rivers or lakes and with limited access to groundwater resources. It is employed in several countries worldwide, with notable examples in Europe, the United States, and parts of Africa. Contamination of surface waters poses a serious threat to attaining drinking water standards.

Probing the unique biology of human pancreatic cancer cells in a laboratory has yielded unexpected insights of a weakness that can be used against the cells to kill them.

A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) studied the effects of processing additives - aluminum hydroxide and zinc stearate - on the polymerization kinetics of thermosets used in pultrusion.

A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping.This is the first time that a measurement has been made of the entropy - or heat loss - generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future technologies, as systems approach the quantum realm.

Neonatal hypothermia -- which occurs when an infant's core body temperature falls below the normal range needed to maintain health -- contributes to approximately one million deaths each year, and countless cases of stunted growth, almost exclusively in low- and middle-income countries. To address this common but preventable condition, researchers from Boston Children's Hospital, engineers at Lawrence Berkeley National Laboratory, and colleagues in Rwanda developed the Dream Warmer, a low cost, reusable non-electric infant warmer to prevent and treat hypothermia.

Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.

A new University of Iowa 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.

Which wound cuts deeper: the loss of an only child or loss of a spouse? A new study led by researchers at NYU Rory Meyers College of Nursing and Fudan University suggests that Chinese parents find the loss of an only child to be approximately 1.3 times as psychologically distressing than the loss of a spouse.

A comprehensive review into what we know about COVID-19 and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called "long-COVID". There is growing evidence that the virus infects both the upper and lower respiratory tracts - unlike "low" or "high" pathogenic" human coronavirus sub-species, which typically settle in one or the other.

In a new project, WVU researchers completed a systematic review of studies that dealt with telehealth and chronic conditions. They found that--in general--telehealth services benefitted patients more if they continued for about a year, rather than ending after six months or so.

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, Halle-Leipzig.

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.

A research team at Carnegie Mellon University recently completed the first in-depth study of browser tabs in more than a decade. They found that many people struggle with tab overload, an underlying reason being that while tabs serve a variety of functions, they often do so poorly.
