Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.

Researchers have introduced a new method for taking high-resolution images of fast-moving and rotating objects in space, such as satellites or debris in low Earth orbit. They created an imaging process that first utilizes a novel algorithm to estimate the speed and angle at which an object in space is rotating, then applies those estimates to develop a high-resolution picture of the target.

Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.

A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the periodic table.

Researchers and their partners have discovered a slimy strategy used by bacteria to defeat antibiotics and other drugs used to combat infections afflicting people with cystic fibrosis.

Robots that could take on basic healthcare tasks to support the work of doctors and nurses may be the way of the future. Who knows, maybe a medical robot can prescribe your medicine someday? That's the idea behind 3D structural-sensing robots being developed and tested right now.

When it comes to learning to read, new research suggests that explicit instruction -- a phonics teaching method in which the relationship between sound and spelling is taught directly and systematically -- is more effective than self-discovery through reading.

Marine protected areas (MPAs) around Oahu do not adequately protect populations of herbivorous reef fishes that eat algae on coral reefs.

Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that can be used to quantify tRNAs in any...

In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect -- a characteristic change in the way electricity is conducted in the presence of a magnetic field -- in a nonmagnetic quantum material to which no magnetic field was applied.

A scientist's research into the geometrical characteristics of a physical theories is highlighted in a new article. A physicist examines what structural property of a theory like quantum mechanics makes it prone to contextuality.

A pair of novel calculators could help hospitals predict patient outcomes and better allocate scarce resources such as ICU beds and ventilators.

When Patrick Rottinghaus began college, he had no idea what he wanted to do with his career. He started out as an "Open" major while he explored possibilities. Today, he is helping young people eager to find their place in the world by identifying their strengths and connecting them with careers that match their skill-set, interests and personality. As the father of three children, including a...

For practical applications, two-dimensional materials such as graphene must at some point connect with the ordinary world of 3D materials. Researchers have come up with a way of imaging what goes on at these interfaces, down to the level of individual atoms, with the goal of better controlling these materials' electronic properties.

Scientists aim to numerically investigative the roles of cooperative effects and disorder in photon escape rates from a cold atomic gas to construct a model that considers the vectorial nature of light. Thus, the study accounts for properties of light, previously neglected.

In a new study, researchers report that a series of biomarkers, or biological signals, associated with white blood cell activation and obesity can predict severe outcomes in COVID-19 patients.

Challenging the idea that older people with shorter life expectancies should rank lower in coronavirus immunization efforts, new research shows that giving vaccine priority to those most at risk of dying from COVID-19 will save the maximum number of lives, and their potential or future years of life.

The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos. That is, the OLEDs are fabricated on to temporary tattoo paper and transferred to a new surface by being pressed on to it and dabbed with water.

Scientists assess the dynamics of positron acoustic waves (PAWS) in EPI plasmas whilst under the influence of magnetic fields, or magnetoplasmas.

A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago.

A researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.

Scientists have identified 62 genes that lead to both higher levels of body fat but a lower risk of cardiovascular and metabolic diseases. These genes may help to keep body fat healthy, and open a new avenue for developing drugs that lower the risk of diabetes and heart disease.

Researchers have discovered that increased levels of the protein OAS1 are associated with reduced mortality and less severe disease requiring ventilation among patients with COVID-19. Using drugs that boost OAS1 levels could be explored to try to improve these outcomes.

People who took statins to lower cholesterol were about 50 percent less likely to die if hospitalized for COVID-19, a retrospective study has found.
