Chemical modification of DNA subunits contribute to the regulation of gene expression. Researchers have now deciphered a new pathway can reactivate genes that have been silenced in this way, while avoiding the risk of da...

Dark matter and dark energy are mysterious, unknown substances that are thought to make up more than 96% of the universe. While we may have never directly seen them, they beautifully explain how stars and galaxies move a...

(Phys.org)--An international team of researchers has conducted an experiment that shows that the arrow of time is a relative concept, not an absolute one. In a paper uploaded to the arXiv server, the team describe their ...

A new targeted treatment could benefit patients with certain pancreatic tumors by preventing spread of the cancer and protecting their heart from damage -- a direct result of the tumor. Higher levels of serotonin among o...

In vaccination, a certain subpopulation of dendritic cells is vital to triggering the body's adaptive immune system, report researchers. Their findings have important implications for vaccine delivery, as the usual metho...

The harmful effects of being overweight have been underestimated, according to a new study that analyzed body mass index (BMI), health and mortality data in around 60,000 parents and their children, to establish how obes...

New experiments validate the identification of five new genes linked to Amyotrophic Lateral Sclerosis (ALS) -- also known as Lou Gehrig's disease. The new study results were validated through five different methods.

While skin pigmentation is nearly 100 percent heritable, it is hardly a straightforward, Mendelian trait. By working closely with the KhoeSan, a group of populations indigenous to southern Africa, the researchers have fo...

Scientists may have found possible targets for therapeutic interventions in the fight against Lou Gehrig's disease. A research team conducted the first single-molecule study of folding in the protein superoxide dismutase...

When we sleep, our organism goes through different phases of sleep, however the brain remains interconnected during non-REM sleep, which was thought not to happen. This finding has also made it possible to analyze the sc...

CERN is taking part in a project, called ARIA, for the construction of a 350-metre-tall distillation tower that will be used to purify liquid argon (LAr) for scientific and, in a second phase, medical use.

A group of scientists at the Niels Bohr Institute (NBI), University of Copenhagen, has figured out how to make spin qubits perform controlled backward rotations. This has never been shown before - and the journal Physica...

Plasmas, gas-like collections of ions and electrons, make up an estimated 99 percent of the visible matter in the universe, including the sun, the stars, and the gaseous medium that permeates the space in between. Most o...
