Hair can be dyed at home or at a salon. Is one safer than the other?

(DOE/Thomas Jefferson National Accelerator Facility) The Electron-Ion Collider Center at the Department of Energy's Thomas Jefferson National Accelerator Facility (EIC Center at Jefferson Lab) has announced the winners o...

Targeted deep brain stimulation may help treat obsessive-compulsive disorder.

In physics, a very intuitive way of describing the evolution of a system proceeds via the specification of functions of the spatiotemporal coordinates. Yet, there often exist other degrees of freedom in terms of which th...

Dopamine neurons in the brain regulate internal processes of economic decision making, evaluating available options, and identifying the most preferable outcome.

What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of thi...

An international team led by physicists from the Ludwig-Maximilians Universitaet (LMU) in Munich realized a novel genuine time-dependent topological system with ultracold atoms in periodically-driven optical honeycomb la...

Premature babies with serious brain haemorrhage treated with a 'brain washing' technique were twice as likely to survive without severe learning disability when compared with infants given standard treatment.

(Forschungsverbund Berlin) Optical amplifiers based on chirped pulse amplification (CPA) are used to generate high intensity pulses. In the CPA scheme, a weak temporally stretched seed pulse is amplified to high energy i...

Injections are two-and-a-half times safer when nurses use revamped guidelines.

The prospect of a non-invasive test of ovarian reserve is a little closer following results from a study showing that measurement of a fertility hormone can be accurately taken from a sample of human hair.

Researchers studied double-strand breaks with complex damage and found that enzyme tools to resect the breaks are highly specific to the type of break to be repaired.

Researchers directly measured oxygen levels in an intact brain and correlated it with neural activity. During normal activity, only 50% of oxygen is used for neural activity, the remaining 50% is required for glial cells...

Frailty and immune decline are two main features of old age. Researchers now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therap...

The brain has a high energy demand and reacts very sensitively to oxygen deficiency. Neurobiologists have now succeeded for the first time in directly correlating oxygen consumption with the activity of certain nerve cel...

The program could make it easier to identify the deadly antimicrobial resistant bacteria that exist in the environment. Such superbugs annually cause more than 2.8 million difficult-to-treat pneumonia or bloodstream infe...

New research identifies several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical and structural inte...

Researchers have discovered a protein that drives the progression of esophageal cancer and liver cancer and it could be a promising target for cancer drug development.

Without stem cells, human life would not exist. Due to them, a lump of cells becomes an organ, and a fertilized egg develops into a baby. But what actually makes a stem cell? Are these a stable population of specially gi...

An international team of experts on heart disease and diet say there's no evidence that a low-saturated fat diet reduces cholesterol in people with familial hypercholesterolemia.

Cell reprogramming provides an outstanding opportunity for the artificial generation of stem cells for regenerative medicine approaches in the clinic. As current cell reprogramming methods are low in efficiency, research...

Researchers have developed a human cell 'membrane on a chip' that allows continuous monitoring of how drugs and infectious agents interact with our cells, and may soon be used to test potential drug candidates for COVID-...
