A new strategy normalizes blood sugars in diabetes

Researchers at Boston Children's Hospital have identified a new strategy to treat type 2 diabetes by activating a cellular pathway that fails in obese individuals. The approach normalizes blood glucose levels in severely obese and diabetic mice, suggesting potential benefits for human treatment.

Fat clue to TB awakening

Researchers have discovered that Mycobacterium tuberculosis stimulates macrophages to accumulate fat droplets, turning them into 'foamy' cells that can reawaken the latent TB infection. This cellular transformation allows the bacteria to leak out into the airways and progressively destroy lung tissue.

Paired drugs kill precancerous colon polyps, spare normal tissue

A combination of Vitamin A acetate and TRAIL kills precancerous colon polyps while sparing normal tissue, providing a potential new avenue for chemoprevention. The regimen, tested in mouse models and human colon cancer tissue, appears to address the issue of continuous long-term therapy required for current chemopreventive drugs.

Sugar-hungry yeast to boost biofuel production

Scientists have developed yeast that efficiently converts a wider range of plant waste sugars into alcohols for biofuel production. The modified yeast can produce both ethanol and butanol, which could replace fossil fuels with superior properties.

Microbial answer to plastic pollution?

A recent study has discovered that certain marine bacteria can form biofilms on plastic fragments, potentially breaking them down. This research could lead to new methods for cleaning up microplastics and reducing their impact on marine life.

Chemical cocktail affects humans and the environment

Researchers found that environmental chemicals form a complex cocktail, leading to greater toxicity than individual chemicals. The EU recommends implementing guidelines for managing the chemical cocktail effect to assess risks to humans and the environment.

Few drive well while yakking on cell phones

A small group of people with the ability to multitask have been found to be able to drive safely while using a cell phone. The study, conducted by psychologists Jason Watson and David Strayer, found that these individuals, known as 'supertaskers,' showed no impairment on their driving performance when also talking on a cell phone.

Promising strategy for treatment of lung cancer

Researchers at the University of Gothenburg have discovered two closely related enzymes, FT and GGT, as promising targets for treating lung cancer. By blocking these enzymes in transgenic mice, they found that cell growth was inhibited, tumour formation decreased, and survival rates improved.

Tiny gold probes give scientists a sense of how disease develops

Researchers developed tiny gold-coated particles that can be implanted into cells, enabling remote disease diagnosis and tracking through laser-induced vibrations of proteins. These probes use different vibrational frequencies to detect disease progression.

Common mechanisms of drug abuse and obesity

A new study by the Scripps Research Institute found that unrestricted access to high-fat foods can trigger addiction-like responses in the brain, leading to compulsive eating behaviors and obesity. The study suggests that type 2 dopamine receptors play a key role in this process.
