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.

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...

For anxious spouses, a baby may be a rival

A new child can spark feelings of jealousy in a person who already fears being abandoned by his or her partner, research suggests. A new study found that partners who showed signs of relationship anxiety before the birth of their first child were more likely to be jealous of the child after it was born.

Magnetic whirls in future data storage devices

Magnetic (anti)skyrmions are microscopically small whirls that are found in special classes of magnetic materials. They could be used to host digital data. A team of scientists has now made the observation that skyrmions and antiskyrmions can coexist bringing about the possibility to expand their capabilities in storage devices.

How a new quantum approach can develop faster algorithms to deduce complex networks

Complex networks are ubiquitous in the real world, from artificial to purely natural ones, and they exhibit very similar geometric properties. Algorithms based on quantum mechanics perform well on such networks, but their relationship with the geometrical characteristics of networks has remained unclear until now. Researchers have now shed light on these relationships, opening up new possibilities...

Alzheimer's: Can an amino acid help to restore memories?

Scientists have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer's restores spatial memory affected early. This is a promising path for reducing memory loss related to that disease.

Plastic from wood

The biopolymer lignin is a by-product of papermaking and a promising raw material for manufacturing sustainable plastic materials. However, the quality of this naturally occurring product is not as uniform as that of petroleum-based plastics. An X-ray analysis carried out at DESY reveals for the first time how the internal molecular structure of different lignin products is related to the...
