Scientists have discovered living microbes producing methane in the fractured rocks deep inside Sweden’s Siljan impact crater, offering insights into Earth’s earliest life and the search for life beyond our planet.

This breakthrough not only sheds light on one of Earth’s most ancient metabolic processes —methanogenesis—but also strengthens the link between meteorite impact structures and microbial survival in extreme environments. The findings are published in the journal mBio.

Methanogenesis is considered one of the earliest metabolisms on Earth, and its presence in deep subsurface environments has long intrigued scientists. Now, for the first time, active microbial methane production has been confirmed in a terrestrial impact crater. Using cultures enriched from fluids 400 meters below the surface, the team demonstrated methane generation from several carbon sources, including indigenous oil.

Scientists found a hidden flaw in prostate cancer’s survival system. Researchers have discovered that prostate cancer depends on two key enzymes, PDIA1 and PDIA5, to survive and resist therapy. When blocked, these enzymes cause the androgen receptor to collapse, killing cancer cells and enhancing the effects of drugs like enzalutamide. They also disrupt the cancer’s energy system, striking it on multiple fronts. This breakthrough could open a new path to overcoming drug $resistance in advanced prostate cancer.

An international team of researchers has identified a new weakness in prostate cancer cells that could lead to more effective treatments for one of the most common cancers among men.

The study, published in the Proceedings of the National Academy of Sciences (PNAS), was led by scientists from Flinders University in Australia and South China University of Technology. Their findings highlight two enzymes, PDIA1 and PDIA5, that play a key role in helping prostate cancer cells grow, survive, and resist existing treatments.

Through substantial leadership turnover and workforce cuts, the FDA has continued to support the advanced therapy sector, actively working to remove obstacles to innovation.

Scientists at the University of Nottingham developed a tooth enamel regeneration gel that rebuilds teeth naturally, a breakthrough in fluoride-free care.
