University of Louisville researchers have discovered how a naturally occurring microbial compound may help protect the gut and support future treatment strategies for inflammatory bowel disease (IBD).

IBD, which includes conditions such as Crohn’s disease and ulcerative colitis, affects millions of people worldwide. The disease is characterized by chronic inflammation and damage to the intestinal lining. A healthy gut barrier helps keep harmful bacteria from leaking out of the intestines while allowing nutrients to enter the body. In people with IBD, that barrier becomes weakened, leading to inflammation, pain and long-term complications.

While biomethane is flowing into homes across the U.S., Asia and Europe, a renewable replacement for natural gas has yet to reach its full potential in Australia.

New research by University of Melbourne scientists has made it easier for biomethane to be used in heating, cooking and transport.

The team, led by Professor Mohsen Talei, studied key contaminants in biomethane to determine safe concentrations for use in home appliances.

Their findings establish guidelines for how much purification biomethane needs before it can reach the market and provide a clearer pathway for scaling up production and making it available for use.

Gas who?
Biomethane is chemically identical to natural gas...

An international collaboration has discovered two of the lowest-density giant planets ever detected: rare “super-puff” planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d’Azur/Observatoire de la Côte d’Azur and the University of Birmingham—has been published in Monthly Notices of the Royal Astronomical Society.

The two planets, named TOI-791 b and TOI-791 c, orbit an F7-type dwar...

A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.

Scientists have long wondered why humans and other animals need to sleep. One potential mechanism is that sleep is required to restore synaptic connections and homeostasis in the brain...
