NASA’s Lucy finds a wobbling peanut-shaped asteroid with signs of ancient water

Black background graphic with a large white title at top. Upper left shows a gray, pea-nut-shaped, rock-like object. Upper right shows a rectangular inset image of a dark textured rock fragment. Near the center are a mission patch logo and a small globe with Antarctica highlighted. Lower half contains two side-by-side charts with axes, tick marks, and blue and green plotted lines with scattered blue data points. Additional white, blue, and green labels appear throughout the graphic.
During its April 20, 2025, encounter with the main-belt asteroid Donaldjohanson, NASA’s Lucy spacecraft discovered evidence for iron-rich clays on the surface using its infrared spectrometer. These clays, which are similar to those found in carbon-rich meteorites such as QUE 97990, indicate that water was briefly present in the asteroid during the distant past.

A bizarre wobbling asteroid revealed by NASA’s Lucy mission is exposing hidden clues about ancient water, cosmic collisions, and the origins of the solar system. NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight...

Scientists unlock gut-healing power of fruits and nuts paired with the right gut microbes

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.

Biomethane as a renewable replacement for natural gas

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...
