Chest CT findings in coronavirus disease (COVID-19) pneumonia

New research on the novel coronavirus (COVID-19) is a multi-center study (n=101) of the relationship between chest CT findings and the clinical conditions of COVID-19 pneumonia -- which determined that most patients with the disease have ground-glass opacities (GGO) (86.1%) or mixed GGO and consolidation (64.4%) and vascular enlargement in the lesion (71.3%). CT involvement score can help evaluate...

Design of inorganic materials for brain-like computing

Ever wish your computer could think like you do or perhaps even understand you? That future may not be now, but it's one step closer, thanks to scientists and engineers and their recent discovery of a materials-based mimic for the neural signals responsible for transmitting information within the human brain.

Can't sleep? Prebiotics could help

New research shows that animals on a prebiotic diet sleep better and are buffered from the physiological impacts of stress. The undigestible dietary compounds, found in fibrous foods and some dairy products, serve as nourishment for beneficial bacteria and influence metabolites that, in turn, impact the brain.

Jellyfish help us understand timing of egg production

In animals, releasing eggs in a timely manner is vital to maximize the chances of successful fertilization. However, how this process evolved and is controlled in different species is poorly understood. A new regulator of egg release has been identified in jellyfish. The finding sheds light on how the complex hormonal control of sexual reproduction in animals evolved.

'It felt like we were in a bad dream:' Tennessee man shares terrifying story of brush with Nashville tornado

James Duncan, 27, had just eased into bed late on Monday night when a smartphone notification from AccuWeather alerted him and his girlfriend, Britni, of a life-threatening tornado that was fast approaching.This vital information was the first warning that they received about the confirmed tornado that was tracking toward their location in Germantown, located just north of downtown Nashville,...

Tornadoes tear though Tennessee, 22 dead

Tornadoes ripped through Tennessee early Tuesday, claiming at least 22 lives as they destroyed buildings and toppled power lines, hours before the southern US state began voting in Super Tuesday primaries.

'Optical tweezers' help in quest for better cancer treatments

Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer and premature aging conditions. Roughly 90% of cancer cells require inappropriate telomerase activity to survive.

Atomic-scale imaging reveals secret to thin film strength

An international team of scientists and engineers, led by University of Minnesota Associate Professor K. Andre Mkhoyan and Professor Emeritus Michael Tsapatsis (currently, a Bloomberg Distinguished Professor at Johns Hopkins University), have made a discovery that could further advance the use of ultra-thin zeolite nanosheets, which are used as specialized molecular filters. The discovery could...

NASA maps show the effect of a quarantine on air pollution

"This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event," said NASA air quality researcher Fei Liu. She made that statement after NASA's Earth Observatory released maps showing a dramatic drop in air pollution in the Wuhan region. Industrial output in the region would have already been down significantly due to the Lunar New Year....

Coral Reefs in Turks and Caicos Islands resist global bleaching event

A study that relied on citizen scientists to monitor the health of corals on Turks and Caicos Islands in the Caribbean from 2012 to 2018 found that 35 key coral species remained resilient during a 2014-17 global coral-bleaching event that harmed coral reefs around the world. Even corals that experienced bleaching quickly recovered, the researchers found. Some corals appeared healthier in 2017 than...
