Using aspirin urgently could substantially reduce the risk of major strokes in patients who have minor 'warning' events. Medical researchers say that immediate self-treatment when patients experience stroke-like symptoms...

Wiping out a mouse's gut bacteria with a long course of antibiotics hinders the growth of new brain cells - but exercise and probiotics can reverse this

A new robot art competition showcases the painting abilities of artificial intelligence.

A group of scientists has succeeded in synthesizing nanoparticles of ultrapure silicon, which exhibited the property of efficient photoluminescence, (secondary light emission after photoexcitation), with the hopes of hig...

A simple and environmentally friendly method for extracting RNA from the cells of bacteria, plants and animals for detecting viruses has been developed by a research team.

During embryonic life, the emergence of body limbs is orchestrated by a family of architect genes, which are themselves regulated by two DNA structures. While the first presides over the construction of the arm, the othe...

Coprophagia, eating one's feces, is common in animals but rarely seen in humans. Now researchers have reviewed the cases of a dozen adult patients diagnosed with coprophagia over the past 20 years and found that the beha...

A biosensor has been proven capable of detecting molecules associated with neurodegenerative diseases and some types of cancer. The device is a single-layer organic nanometer-scale transistor on a glass slide. It contain...

To make the world safer against future infectious disease threats, national health systems should be strengthened, the World Health Organization's emergency and outbreak response activities should be consolidated and bol...

Recently, a team of scientists examined the whole-joint gene expression by RNA sequencing at one day, one, six and 12 weeks after injury. The team used a new, non-invasive tibial compression mouse model of PTOA, that mim...

A new step in cancer immunotherapy: researchers show that even if one's own immune cells cannot recognize and fight their tumors, someone else's immune cells might.

Brain tumors subject to therapy can become resistant to it through interactions with their tumor microenvironment rather than because of anything intrinsic about the tumor itself, a new study in mice suggests.

A key biochemical enables bacteria to repair otherwise fatal damage to their DNA, including that caused by antibiotics, report scientists. The study results revolve around the delicacy of DNA molecules, the letters makin...

A team of scientists working at the U.S. Department of Energy's (DOE) Argonne National Laboratory and led by Northern Illinois University physicist and Argonne materials scientist Zhili Xiao has created a new material, c...

Researchers have created a device for detecting cardiac arrhythmias in real time, and that turns portable a system that uses electrodes placed on the chest of the patient or as part of clothing (shirt), plus it allows to...

People who drink too much and those with higher household incomes would pay more following an increase in state alcohol taxes than those who drink less and have lower household incomes, according to a new study.

High levels of the protein p62 in human liver samples are strongly associated with cancer recurrence and reduced patient survival, scientists have discovered. In mice, they also found that p62 is required for liver cance...

A strain of inbred mice commonly used for the creation of so-called knockout animals has been found to carry a previously undetected mutation that could affect the results of immune system research studies.

Scientists have discovered an important biological phenomenon in human cells that will help scientists design safer treatments to prevent mitochondrial diseases. The team first pioneered a technique, mitochondrial replac...

A malicious form of ATF2, a protein that drives the formation of melanoma, has been discovered by a research team. In a new study, researchers looked at the oncogenic potential of a 'dead' form of ATF2 in mice with mutat...

Studying fruit flies, whose sleep is remarkably similar to that in people, researchers say they've identified brain cells that are responsible for why delaying bedtime creates chronic sleepiness.

A new study has identified a 'sunscreen' gene that may help stave off skin cancer. Researchers found that the 'UV radiation Resistance Associated Gene' is a tumor suppressor for skin cancer, which is the most common form...
