Artificial intelligence tracks aging and damaged cells through high resolution imaging

A combination of high-resolution imaging and machine learning, also known as artificial intelligence (AI), can track cells damaged from injury, aging, or disease, and that no longer grow and reproduce normally, a new study shows.

Multi-contaminant water treatment could prevent tens of thousands of cancer cases

Drinking water treatment that pursues a multi-contaminant approach, tackling several pollutants at once, could prevent more than 50,000 lifetime cancer cases in the U.S., finds a new peer-reviewed study by the Environmental Working Group.

Stem cells transform into bone cells by squeezing through narrow spaces

In a discovery that could reshape approaches to regenerative medicine and bone repair, researchers have found that human stem cells can be prompted to begin turning into bone cells simply by squeezing through narrow spaces.

New small molecule shows promise against cutaneous HPV infections

Human papillomaviruses, or HPVs, can cause dangerous infections in the skin and mucous membranes and may lead to cancer.

Bayesian neural networks advance understanding of gut microbe metabolism

Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body's chemistry and each other.

Early exposure to plastics raises young children’s asthma risk

A large international study found that early-life exposure to phthalates, common chemicals in plastics, is modestly associated with increased risks of asthma, wheeze, and rhinitis in children under five. No consistent associations were found for bisphenols, and effects were generally small.

Early life exposure to PFHxA may impact male brain development

"Forever chemicals" or per- and polyfluoroalkyl substances (PFAS) have been widely used in consumer and industrial products for the better part of a century, but do not break down in the natural environment.

EU researchers call for wider use of alternatives to animal testing

Researchers examine how the use of animal testing to identify endocrine-disrupting substances in the EU can be reduced. Although it is, in principle, possible to identify such substances without using animals, non-animal methods are still rarely applied.

Cornell scientists use natural cell proteins to track molecular behavior

Cornell researchers have found a new and potentially more accurate way to see what proteins are doing inside living cells - using the cells' own components as built-in sensors.

Electrical stimulation boosts math skills in people with weaker neural links

The strength of certain neural connections can predict how well someone can learn math, and mild electrically stimulating these networks can boost learning, according to a study published on July 1st in the open-access journal PLOS Biology by Roi Cohen Kadosh from University of Surrey, United Kingdom, and colleagues.

Researchers find gut bacteria rapidly soak up ‘forever chemicals’

Scientists have demonstrated that select human gut bacteria can bioaccumulate and sequester PFAS ‘forever chemicals’, increasing faecal excretion in humanized mice. The findings reveal a potential microbiome-based strategy to reduce PFAS body burden, though clinical benefit in humans remains unproven.

Beetle-inspired tuberculosis testing device offers accurate detection for people with HIV

Current tuberculosis infection tests struggle to detect the disease in those with HIV. A common co-infection, HIV can hide TB from traditional tests by eliminating the immune cells relied upon to sound the alarm.

Pesticides found to disrupt specific gut bacteria linked to inflammation

While emerging evidence suggests pesticides can be toxic to the mix of microorganisms in the digestive system, a new study is the first to map changes to specific gut bacteria based on interactions between human microbes and insect-killing chemicals observed in the lab and an animal model.

New 3D printed breast tissue model sheds light on milk production

Human breast milk is uniquely adapted to meet an infant's nutritional needs. Surprisingly, we still know very little about how milk is even made in the breast.

New insights into the role of diet and microbiome in gastric cancer

Gastric cancer (GC), once primarily seen in older adults, is on the rise among younger individuals in developed countries.

How a novel reaction in E. coli helps recycle plastic into paracetamol

Researchers have demonstrated that E. coli can perform a biocompatible Lossen rearrangement, enabling phosphate-catalysed conversion of synthetic substrates into valuable compounds. This approach allows engineered bacteria to upcycle PET plastic waste into paracetamol, highlighting a novel intersection of chemistry and biotechnology.

Stress-activated gene damages insulin-producing cells in type 2 diabetes

Stress does no one - not even your insulin-producing cells - any good.

Common bacterium can turn everyday plastic waste into paracetamol

Paracetamol production could be revolutionized by the discovery that a common bacterium can turn everyday plastic waste into the painkiller, a study reveals.

Researchers turn a deadly fungus into potent cancer-fighting compound

Penn-led researchers have turned a deadly fungus into a potent cancer-fighting compound. After isolating a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to deaths in the excavations of ancient tombs, the researchers modified the chemicals and tested them against leukemia cells.
