Immunological scarring from coeliac disease

A new study suggests that coeliac disease permanently replaces 'tissue-healing' T cells with 'pro-inflammatory' T cells in the bowel, causing chronic inflammation and potentially contributing to other intestinal disorders. The research has implications for gut health in affected patients.

New research center at TU Graz

The COMET Project aims to create a low-carbon special powertrain research center at TU Graz, focusing on CO2-neutral fuels, hybrid drive technology, and electric powertrain components. The four-year project is funded by six million euros and strengthens Austria's research and production location.

Social threat learning influences our decisions

Researchers found that social threat learning, such as watching a video or receiving oral instructions, can influence decision-making just as strongly as first-hand experience. Participants who learned a certain image was dangerous continued to avoid it, even when it led to more shocks, indicating irrational behavior.

Cracking colibactin's code

Researchers studied how colibactin damages DNA and created a novel technique to identify DNA adducts. They isolated and characterized the products of the reaction with DNA, revealing a cyclopropane ring structure that forms the colibactin warhead.

What's age got to do with it?

New research from the European Society of Cardiology shows that physiological health, as measured by exercise stress testing performance, is a better predictor of survival than chronological age. This finding suggests that individuals who are physically fit may live longer than those who are not.

How proteins become embedded in a cell membrane

A team of ETH Zurich researchers used single-molecule force spectroscopy to investigate how membrane proteins become embedded in cell membranes. They discovered the role of two helper proteins, insertase and translocase, which enable membrane proteins to embed themselves in the membrane. The study sheds light on the folding pathways of...

Gravitational waves will settle cosmic conundrum

Measurements of gravitational waves from binary neutron stars will definitively resolve the debate on the universe's expansion rate. By observing 50 binary neutron stars over the next decade, scientists can calculate the Hubble constant accurately, resolving the conflict between conflicting measurements.
