For The Better

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms — more commonly known as ‘long COVID’ — up to six months after recovering, according to researchers. The …

Biologists have found that mother roundworms can pass stress signals to future generations. The biologists report a mother roundworm exposed to a stressor can even under certain conditions pass the memory of that exposure to their grandchildren.

Solar prominences hover above the visible solar disk like giant clouds, held there by a supporting framework of magnetic forces, originating from layers deep within the Sun. The magnetic lines of force are moved by ever-present gas currents — and when…

Researchers found that estimated Pulse Wave Velocity (ePWV), a readily available marker of arterial stiffness, has been shown to be an effective addition in identifying patients at risk of mortality in hospital due to COVID-19.

Researchers have theoretically demonstrated that the correlations of light can be controlled with a metamaterial known as enhanced epsilon-near-zero (eENZ) materials. The material allows small and high-quality lasers that are expected to have applicati…

Researchers have developed a new nanomechanical technique for fast, one-step, immune-affinity tests, which can quantify the immune response induced by different COVID-19 variants in serum. Their technique provides a new tool for tracking infection immu…

For over 100 years, physicists, chemists, and materials scientists have developed extensive theoretical and experimental machinery to predict and characterize the electronic properties of magnetic materials, but even the most successful classification …

The prognosis for a cancer patient who undergoes surgery is better if the surgeon removes all of the tumor, but it can be hard to tell where a tumor ends and healthy tissue begins. Now, scientists report that they have developed a fluorescent spray tha…

When an asteroid struck 66 million years ago and wiped out dinosaurs not related to birds and three-quarters of life on Earth, early ancestors of primates and marsupials were among the only tree-dwelling (arboreal) mammals that survived, according to a…

New research found that patients who used drugs prescribed to treat heartburn, acid reflux and ulcers were more likely to have smaller probing depths in the gums (the gap between teeth and gums).

Converting advances in scientific knowledge and innovations in cardiac care into improvements in patient outcomes requires comprehensive cardiac systems of care optimize cardiac care delivery. New recommendations support policies that standardize the d…

Leading a double life in water and on land, frogs have many breathing techniques — through the gills, lungs, and skin — over the course of their lifetime. Now scientists have developed another method that allows tadpoles to ‘breathe’ by introducing a…

Human feces don’t usually stick around for long — and certainly not for thousands of years. But exceptions to this general rule are found in a few places in the world, including prehistoric salt mines of the Austrian UNESCO World Heritage area Hallsta…

Leprosy has been found in wild chimpanzees. Researchers have confirmed cases of the disease among two unconnected West African populations of chimpanzees, in Guinea-Bissau and the Ivory Coast.

A group of researchers have created an unusual material — a soft crystal made of molecules known as a catenanes– that behaves in a novel way that could be used in applications such as films that capture carbon dioxide molecules.

The planet Venus can be seen as the Earth’s evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere. Yet, a closer look reveals striking differ…

Scientists have developed a topology-based method that forces microwave photons to travel along on way path, despite unprecedented levels of disorder and obstacles on their way. This discovery paves the way to a new generation of high-frequency circuit…
