The famous impact 66 million years ago kicked up soot into the atmosphere that played an even bigger role in blocking sunlight than experts had realized

Hydrogen is a possible next generation energy solution, and it can be produced from sunlight and water using photocatalysts. A research group has now developed a strategy that greatly increases the amount of hydrogen produced using hematite photocatalysts. In addition to boosting the high efficiency of what is thought to be the world's highest performing photoanode, this strategy will be applied to artificial photosynthesis and solar water-splitting technologies via university-industry collaborations.

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a greater distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly lossless exchange of information and strong interaction between them. The physicists reported that the new method opens up new possibilities in quantum networks and quantum sensor technology.

Researchers discover what is happening at the cellular level when Castleman patients experience a cytokine storm.

Scientists have developed a method that combines different resolution levels in a computer simulation of biological membranes. Their algorithm backmaps a large-scale model that includes features, such as membrane curvature, to its corresponding coarse-grained molecular model. This has allowed them to zoom in on toxin-induced membrane budding and to simulate a full-sized mitochondrial lipid membrane. Their approach opens the way to whole-cell simulations at a molecular level.

Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. Scientists have now uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of agricultural applications.

Millions of people around the world use acid suppressants called proton pump inhibitors for conditions like heartburn, gastritis and stomach ulcers. Researchers at Karolinska Institutet in Sweden now report that how the long-term use of these drugs could increase the risk of developing dementia. Their results are published in the journal Alzheimer's & Dementia.

A new study finds that temperature and latitude do not appear to be associated with the spread of coronavirus disease 2019 (COVID-19), but school closures and other public health measures are having a positive effect.

In many fish species body size plays an important role in sexual selection. Large individuals are preferred mating partners because they can enhance offspring survival by providing better quality resources than small individuals. While large females and males are often favored by sexual selection, fishing targets and removes these reproductively superior individuals.

The brain has a powerful ability to remember and connect events separated in time. And now, in a new study in mice, scientists have shed light on how the brain can form such enduring links.

Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development.

Hematopoietic stem cells from a healthy donor can help patients suffering from acute leukemia. However, the side effects of therapies are often severe. Researchers have now shown how human healthy and cancerous hematopoietic stem cells can be more selectively eliminated using immunotherapy instead of chemotherapy in mice. The aim is to test the new immunotherapy in humans as soon as possible.

Catering companies are having to get creative to stay in business during COVID-19.

The plunge in jobs was 73,800 relative to February, but Saskatchewan saw a shallower decline than any other province as COVID-19 devastates labour markets across Canada.
