Dietary compounds found to influence gut metabolites, buffering stress. Think dietary fiber is just for digestive health? Think again.

Specific fibers known as prebiotics can improve sleep and boost stress resilience by influencing gut bacteria and the potent biologically active molecules, or metabolites, they produce, new University of Colorado Boulder research shows.

The research could ultimately lead to new approaches to treating sleep problems, which affect 70 million Americans.

“The biggest takeaway here is that this type of fiber is not just there to bulk up the stool and pass through the digestive system,” said Robert Thompson, a postdoctoral researcher in the Depa...

With a small zap of electricity, biomedical engineers at Michigan Technological University take an underwater smart glue prototype from sticky to not in seven seconds.

Turning adhesion on and off is what makes a glue smart. It’s one thing to do this in the open air and quite another under water. Inspired by nature, catechols are synthetic compounds that mimic the -but-still- proteins secreted by mussels and offer promise for smart adhesives that work in water. The technology could help with underwater glue, wound dressings, prosthetic attachments or even making car parts and in other manufacturing.

Scientists have identified a sub-atomic particle that could have formed the ‘dark matter’ in the Universe during the Big Bang. Nuclear physicists are putting forward a new candidate for dark matter – a particle they recently discovered called the d-star hexaquark.

Up to 80% of the Universe could be dark matter, but despite many decades of study, its physical origin has remained an enigma. While it cannot be seen directly, scientists know it exists because of its interaction via gravity with visible matter like stars and planets. Dark matter is composed of particles that do not absorb, reflect or emit light.

Now, nuclear physicists at the University of York are p...
