Chemical bonds within the eye-lens protein gamma-B crystallin hold the protein together and are important for the function of the protein. Contrary to previous assumptions, some of these bonds, called disulphide bridges, are already formed simultaneously with the synthesis of the protein in the cell. This is what scientists have recently discovered.

A double-blind Phase 3 international trial investigated whether semaglutide could help to reduce boy weight in overweight individuals. A third of participants who took the drug lost more than twenty percent of their total body weight.

For a drug to be effective at the right places in the body, it can help if it can be predicted accurately how the molecules of that drug will interact with human cells. For the first time, a blueprint of the neuropeptide Y receptor Y2 with one of its ligands is available, enabling the development of tailor-made drugs, for example, to treat epilepsy or cardiovascular diseases.

Researchers describe two possibilities being explored by scientists in the field to make vaccines more effective and build surfaces that could fight and kill viruses on their own.

The World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) yesterday produced guidelines for the emergency use of the ChAdOx1 nCoV-19 coronavirus vaccine developed by the University of Oxford with its partner AstraZeneca.

Researchers have created the exact replica of a bone using a system that pairs biothermal imaging with a heated "nano-chisel". The work could lead to efficient, detailed artificial bone tissue, opening doors to disease modeling, in vitro cell research on targeted therapies, drug screening and more.

An international research team has developed a rapid test that can reliably identify SARS-CoV-2 antibodies in the blood within minutes. The new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories in less economically developed regions.

One of the dozens of unusual symptoms that have emerged in COVID-19 patients is a condition that's informally called "COVID brain" or "brain fog." It's characterized by confusion, headaches, and loss of short-term memory. In severe cases, it can lead to psychosis and even seizures. It usually emerges weeks after someone first becomes sick with COVID-19.Now, researchers have reported an underlying cause of COVID brain: the presence of inflammatory molecules in the liquid surrounding the brain and spinal cord (called the cerebrospinal fluid).

Past research has indicated that, to some degree, people become deal prone through being taught by their parents. But a new paper, "Born to Shop? A Genetic Component of Deal Proneness," provides evidence that our genes also play a role in causing bargain-hunting enthusiasm.

An electrocardiogram (ECG) is an examination that records the electrical activity of the heart during the cardiac cycle. New advances have shown ways to automate the recording of ECGs.
