New method can tell how long bacteria takes to wait out antibiotics

May 11, 2025 • 10:30 AM

The rise of antibiotic-resistant bacteria is a major health concern in treating infectious diseases. Scientists at the Hebrew University of Jerusalem have developed a new method for measuring the time it takes to destroy a bacterial population. This could be used to successfully treat bacterial infections that are becoming multi-drug resistant.

Bacteria can gain resistance by collecting mutations. Mutations are changes in DNA, which can ultimately lead to changing the behavior of bacteria. As a...

You have proteins on your mind

Food cravings are something we are all familiar with but scientists have only just begun to understand the science behind them.

In a new study by
Professor Mark N. Wu at John Hopkins University, published in Science, scientists established the circuit of brain cells which controls fruit fly hunger for a protein diet. This is especially important for understanding how the brain controls hunger for certain nutrients may help in the treatment of obesity in humans.

Animals are known to change...

Sleep unlocks secret of youth for the elderly

recent review published in Neuron highlighted that the aging population are more likely to suffer memory loss as well as a wide range of mental and physical disorders, such as diabetes, heart attacks, stroke, depression and even cancer, if their...

New treatment might provide faster recovery from Tuberculosis

May 11, 2025 • 10:30 AM

A study has revealed that that a new drug regimen for tuberculosis could reduce treatment time by up to 75% as well as cutting the risk for the development of drug-resistant Tuberculosis (TB) in patients.

According to the World Health Organisation, an estimated 10.4 million new cases of TB were reported in 2015 and of those 1.8 million died. There were also at least 480,000 new cases of multi-drug resistant TB in 2015. It comes as no surprise that TB is a global health problem as it overtakes HIV...

Genes not solely to blame for different types of autism

May 11, 2025 • 10:30 AM

Scientists have revealed a new cause of autism spectrum disorders that has nothing to do with your DNA. These disorders share similar modifications in the brain that are independent of genetic activity.

The
study, conducted at the Genome Institute of Singapore, showed that nearly 70% of individuals with both rare and common types of autism spectrum disorder display a similar pattern of histone acetylation.

Histone acetylation is the chemical change of the scaffold around which DNA wraps itself....
