One of the greatest mysteries of the COVID-19 pandemic is why some people fall severely ill while others suffer nary a sniffle. Now, after compiling data from around the world, researchers have determined that the answer seems to lie, in part, in genetics. Through an international meta-analysis of studies from more than […]

For much of human history, animals and plants were perceived to follow a different set of rules than rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by non-physical energy or “life force” that allowed them to perform remarkable […]

The study, carried out by researchers at the Universities of Bristol, Oxford and the Liverpool School of Tropical Medicine, was designed to measure how tsetse offspring health is influenced by their mothers’ age, and how factors such as the mother’s nutrition and mating experience might come into play. In many […]

With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of […]

A skin pigmentation mechanism that can darken the color of human skin as a natural defense against ultraviolet (UV)-associated cancers has been discovered by scientists at Massachusetts General Hospital (MGH). Mediating the biological process is an enzyme, NNT, which plays a key role in the production of melanin (a pigment […]

Biochemists at Emory are achieving insights into how an important regulator of the immune system switches its function, based on its orientation and local environment. New research demonstrates that the glucocorticoid receptor (or GR) forms droplets or “condensates” that change form, depending on its available partners. Understanding how the GR […]

Recovered COVID-19 patients retain broad and effective longer-term immunity to the disease, suggests a recent Emory University study, which is the most comprehensive of its kind so far. The findings have implications for expanding understanding about human immune memory as well as future vaccine development for coronaviruses. The longitudinal study, […]

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments. Drugs must be safe […]

New research in humans and mice identifies a particular signaling molecule that can help modify inflammation and the immune system to protect against Alzheimer’s disease. The work, which was led by investigators at Massachusetts General Hospital (MGH), is published in Nature. Cognitive decline associated with Alzheimer’s disease develops when neurons begin to die. “Neuron […]

As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight? A new Yale study suggests that, in a sense, mammals dream about the world they are about to […]

Magnetic field could boost blood vessel growth to regenerate damaged tissue. Magnetic field can be used to stimulate blood vessel growth, according to a study published in the journal Science and Technology of Advanced Materials. The findings, by researchers at the Tecnico Lisboa and NOVA School of Science and Technology […]

Understanding the structure of proteins can help understand their function; however, existing computational methods fail to predict 3D structures of proteins with atomic accuracy. Thankfully, a recent paper on Nature introduces a redesigned version of a neural network-based model AlphaFold. It can predict protein structures with accuracy competitive with the experiment […]
