Bioactive compounds with possible industrial applications are identified in extremophilic bacteria from the Andes

Biofilm produced by Pseudomonas alcaligenes has unique structural properties and thermal stability, exhibiting antioxidant, emulsification and flocculation activity. The EPS can be used as a natural additive for the pharmaceutical and food industries with potential applications in developing sustainable or ecofriendly additives.

Deep underground flooding beneath arima hot springs: A potential trigger for the 1995 Kobe (Hyogo-Ken Nanbu) earthquake

A study found that a significant increase in plate-derived water beneath Arima Hot Springs occurred before the 1995 Kobe earthquake, potentially weakening the fault and triggering the quake. This phenomenon is similar to increased chloride ions and radon in groundwater, which have been reported as precursors to earthquakes.

Study uncovers potential origins of life in ancient hot springs

Researchers at Newcastle University discovered that mixing hydrogen, bicarbonate, and iron-rich magnetite can form organic molecules, including fatty acids. These findings suggest that life's essential molecules could be produced from inorganic chemicals, shedding light on the origins of life on Earth.

Extremely harsh volcanic lake shows how life might have existed on Mars

A recent study discovered that a hydrothermal crater lake in Costa Rica's Poás volcano is home to a diverse range of microorganisms, including the single 'extremophile' genus Acidiphilium. These bacteria have adapted to survive in extreme conditions, such as high temperatures and toxic metals, which may be similar to those found on Mars.

Did our early ancestors boil their food in hot springs?

Researchers at MIT and the University of Alcalá in Spain discovered evidence of hot springs near early human archaeological sites in Olduvai Gorge. The proximity of these hydrothermal features raises the possibility that early humans could have used hot springs as a cooking resource, boiling fresh kills before controlling fire.

Capturing bacteria that eat and breathe electricity

Researchers at Washington State University captured heat-loving bacteria that can 'eat' pollution by converting toxic pollutants into less harmful substances and generating electricity. The discovery was made possible by a cheap portable potentiostat invented by graduate student Abdelrhman Mohamed, who worked with Professor Haluk Beyenal.

A microbial hot spring in your basement

A nationwide study found microbes in about half of homes, with a single species dominating all positive samples. Despite their presence, the microbes pose no health concerns and remain safe to drink. The discovery highlights the widespread colonization of water heaters by extremophiles in domestic environments.

Exciting new creatures discovered on ocean floor

Scientists at the University of Southampton have discovered six new animal species in undersea hot springs off the coast of Madagascar. The unique marine life was found around hydrothermal vents, highlighting the importance of exploring other hydrothermal vents in the southwest Indian Ocean to assess potential impacts from mining.

Caught in the act: Team discovers microbes speciating

Researchers have discovered two distinct groups of Sulfolobus islandicus bacteria speciating in a hot spring habitat, despite shared genetic material and gene exchange. The study reveals that these groups are already separate species, with differences spanning only 0.35% across the entire chromosome.

Quake in Alaska changed Yellowstone geysers

Scientists found prolonged changes in hydrothermal activity after a magnitude-7.9 Denali fault earthquake in Alaska triggered more than 1,000 small earthquakes in Yellowstone within a week. Some geysers erupted more frequently while others less often due to changes in water pressure and underground conduits.
