Advance in programmable synthetic materials

DNA information is stored in a sequence of chemical building blocks; computers store information as sequences of zeros and ones. Researchers want to transfer this concept to artificial molecules. Researchers have taken another step toward encoding information in the sequence of metal atoms in metal-organic frameworks (MOFs), showing how to read the sequence. Multivariate MOFs could encode digital...

Strong link found between abnormal liver tests and poor COVID-19 outcomes

Researchers found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies. They also discovered that higher levels of liver enzymes -- proteins released when the liver is damaged -- were associated with poorer outcomes for these patients, including ICU admission, mechanical ventilation, and death.

Newly discovered mutation could point to heart disease therapeutic target

New work identifies a potential therapeutic target for clogged arteries and other health risks that stem from an excess of harmful fats in the bloodstream. The study opens the door for the design of more specific MTP inhibitors that could reduce circulating triglyceride levels without the risk of unpleasant and serious side effects in the intestines and liver.

Pinpointing the cells that keep the body's master circadian clock ticking

Scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice. The method gives new insight into which brain cells are important in maintaining the body's master circadian clock. But they say the approach will also be broadly useful for answering questions about the daily rhythms of cells throughout...

Atlantic hurricanes linked to weather system in East Asia

Climate researchers have found a link between hurricanes that form in the Atlantic Ocean - and threaten the United States - and a weather system in East Asia. A jet stream originating in East Asia carries an atmospheric wave to the Atlantic Ocean that affects wind shear - a key element in whether tropical storms develop.

Oldest enzyme in cellular respiration isolated

Researchers have found what is perhaps the oldest enzyme in cellular respiration. They have been able to isolate the extremely fragile 'Rnf' protein complex from the heat-loving bacterium Thermotoga maritima. In fact, the genes that encode for the enzyme were already discovered. However, the researchers have now succeeded for the first time in isolating the enzyme and thus in proving that it...

COVID-19: The virus and the vasculature

In severe cases of COVID-19, the infection can lead to obstruction of the blood vessels in the lung, heart and kidneys. Researchers have now shown that activated immune cells and blood platelets play a major role in these pathologies.

A titanate nanowire mask that can eliminate pathogens

Researchers are working on a membrane made of titanium oxide nanowires, similar in appearance to filter paper but with antibacterial and antiviral properties. Their material works by using the photocatalytic properties of titanium dioxide: when exposed to ultraviolet radiation, the fibers convert resident moisture into oxidizing agents such as hydrogen peroxide, which have the ability to destroy...
