Researchers have upgraded a key computer code for calculating forces acting on magnetically confined plasma in fusion energy experiments. The upgrade will help scientists further improve the design of breakfast-cruller-shaped facilities known as stellarators.
New research provides the first-ever, atomic-level, 3D structure of the largest protein complex (complex I) involved in the plant mitochondrial electron transport chain. The results could unlock new advances in agriculture.
With over 170,000 COVID-19 deaths to date, and 1,000 more each day, America's life expectancy may appear to be plummeting. But in estimating the magnitude of the pandemic, demographers have found that COVID-19 is likely to shorten the average US lifespan in 2020 by only about a year.
When researchers sought to understand the mechanical behaviors of disordered proteins in the lab, they expected that after being stretched, one particular model protein would snap back instantaneously, like a rubber band. Instead, this disordered protein relaxed slowly, taking tens of minutes to relax into its original shape -- a behavior that defied expectations, and hinted at an inner structure...
A new article looks at the use of virtual imaging trials in effective assessment and optimization of CT and radiography acquisitions and analysis tools to help manage the coronavirus disease (COVID-19) pandemic.
A team of scientists has concluded that our cognitive limitations lead to probability distortions and to subsequent errors in decision-making.
X-ray images show a plant's power source may be different than thought.
In the largest observational study of hydroxychloroquine and azithromycin, the drug combination has been linked to significant cardiovascular risks, including death.
In a new study, researchers took a first look at one particular medication for treatment of anxiety disorders in pediatric patients to see if it was beneficial.
A newly developed genotyping 'chip' -- the first of its kind for corals -- allows researchers to genetically identify corals and the symbiotic algae that live within the coral's cells, a vital step for establishing and maintaining genetic diversity in reef restoration efforts.
A new study questions conventional methods of calculating carbon emissions liability based on point source pollution by introducing new 'bottleneck' theory.
Higher rates of e-cigarette and marijuana use in U.S. states did not result in more e-cigarette or vaping-related lung injuries (known as EVALI), a new study from the Yale School of Public Health finds.
A team has created a computational model of the proteins responsible for the transformation of mercury to toxic methylmercury, marking a step forward in understanding how the reaction occurs and how mercury cycles through the environment.
Imagine a tropical forest, and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys, and ... rain. Indeed, precipitation patterns, along with temperature, dictate where tropical forests are distributed around the world, but surprisingly, scientists know very little about the direct effects of rainfall on animals. A new conceptual framework calls for the...
Origami can be used to create mechanical, binary switches, and researchers report the fabrication of such a paper device, using the Kresling pattern, that can act as a mechanical switch. By putting several together on a single platform, the investigators built a functioning mechanical memory board. They found that oscillating the platform up and down at a certain speed will cause it to flip, or...
Researchers discovered a new way cells can dispose of misfolded proteins that may help better understand human NGLY1 deficiency.
Single-cell analysis, done in three colon cancer cell lines, is believed to be the first to profile transcriptome-level changes in response to DNA damage across individual cells.
Wearing a mask while out in public has become the recommended practice during the COVID-19 pandemic. Researchers have now experimentally visualized the flow fields of coughs under various common mouth covering scenarios.
If the mist in a dentist's office -- sent flying into the air by spinning, vibrating tools -- contains a virus or some other pathogen, it is a health hazard. So researchers studied the viscoelastic properties of food-grade polymers and discovered that the forces of a vibrating tool or dentist's drill are no match for them. Not only did a small admixture of polymers completely eliminate...
Contrary to earlier observational results, vitamin D supplements do not prevent severe asthma attacks in at-risk children, according to the first placebo-controlled clinical trial to test this relationship.
Discussions of the growing plastic waste problem often focus on reducing the volume of single-use plastic packaging items such as bags, bottles, tubs and films.
Scientists have discovered a novel anti-aging defense in the brain cells of adult fruit flies: producing extra copies of the genome, according to a new study.
New archaeological research in Saudi Arabia documents hundreds of stone structures interpreted as monumental sites where early pastoralists carried out rituals.
To help keep first responders safe, researchers have developed an artificial intelligence method that not only rapidly and remotely detects the powerful drug fentanyl, but also teaches itself to detect any previously unknown derivatives made in clandestine batches. The method uses infrared light spectroscopy and can be used in a portable, tabletop device.
