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.

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.

New research revisits the Turing instability mechanism; proving mathematically how the instabilities which give rise to patterns can occur through simple reactions, and in widely varied environmental conditions.

Researchers have successfully determined the characteristics of electron emission when high-velocity ions collide with adenine - one of the four key nucleobases of DNA.

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...

Researchers have harnessed the technology to target gene messages (messenger RNA) involved in early vertebrate development.

A key component of the Gulf Stream has markedly slowed over the past century -- that's the conclusion of a new research paper.

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.

Image data reanalysis has revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Jupiter's moon Ganymede. Computer simulation results suggest that this giant crater could have resulted from the impact of an asteroid with a 150-kilometer radius. If so, this the largest impact structure identified in the solar system so far.

Each cigarette smoked a day by heavier smokers increases the risk of contracting some diseases by more than 30 per cent, according to a new study.

Scientists have unveiled a correlation between high blood lead levels in children and methylation of genes involved in haem synthesis and carcinogenesis, indicating a previously unknown mechanism for lead poisoning.

Geologists have developed a machine learning technique that highlights the potential for further deposits of the critical metal tungsten in SW England.

A group of researchers has discovered why the western subarctic Pacific Ocean, which accounts for only 6 percent of the world's oceans, produces an estimated 26 percent of the world's marine resources.

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...

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.

Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists now report on a hydrothermal mechanism that could have promoted the process.

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...

Plants recognize beneficial microbes and keep harmful ones out, which is important for healthy plants production and global food security. Scientists have now discovered how legumes use small, well-defined motifs in receptor proteins to read molecular signals produced by both pathogenic and symbiotic microbes. These remarkable findings have enabled the researchers to reprogram immune receptors...

A new study warns that even with some lockdown measures staying in place to the end of 2021, without more structural interventions global temperatures will only be roughly 0.01°C lower than expected by 2030. However, the study estimates that including climate policy measures as part of an economic recovery plan with strong green stimulus could prevent more than half of additional warming expected...

Unhealthy dietary patterns are a leading cause of heart disease and stroke as well as other chronic diseases. Clinician-delivered diet counseling can improve diet behaviors and heart disease risk factors. Quick, simple dietary assessment tools can be a part of routine office visits and integrated into electronic health records for follow-up.

Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study. The study mapped Southern Alps ice loss from the end of the Little Ice Age -- roughly 400 years ago -- to 2019. It found that relative to recent decades, the Southern Alps lost up to 77% of their total Little Ice Age glacier volume.

Researchers created a reporter mouse strain in pursuit of a new way to answer an old question: Is purinergic receptor gene P2X2 expressed in particular populations of sensory nerve cells? They were surprised, but encouraged, to find P2X2 expressed in a very limited subset of neurons.

Engineers have demonstrated that drug levels inside the body can be tracked in real time using a custom smartwatch that analyzes the chemicals found in sweat. This wearable technology could be incorporated into a more personalized approach to medicine -- where an ideal drug and dosages can be tailored to an individual.

Scientists succeeded in promoting plant growth and increasing seed yield by heterologous expression of protein from Arabidopsis (artificially modified high-speed motor protein) in Camelina sativa, which is expected as a useful plant for biodiesel. The study is expected to apply to other plant resources for biodiesel, such as corn, rice, and sugar cane.
