The brain of one of popular culture’s most infamous dinosaurs helps to clarify its diet and hearing range.

A new way to detect ET life using chemical profiles Rather than detecting one chemical at a time, scientists taught machine learning algorithms what different mixtures of compounds from living and non-living sources “look like” to chemical analyzers. The computer then used those fingerprints to correctly identify living and non-living samples in the lab!

Researchers found a new way to tell the difference between the chemicals of life and the chemicals of non-life...using machine learning!

This fossil is the last common ancestor of worms Ikaria wariootia, a fossil, is predicted to be 560-551 million years old and thought to be the last common ancestor of bilaterians, like worms, found in South Australia.

When did simple life become more complex, such as the modern animals we see today? A recent study may have uncovered evidence for one of these turning points. At Nilpena National Heritage Site, South Australia, scientists discovered new fossils that have never been seen before.

Fungi may be able to help clean up polluted water A few species of fungi were tested for their ability to clean up wastewaters contaminated with selenium. With additional nutrients added, it mostly worked. The fungi Alternaria showed great potential for cleaning up water polluted with selenite.

3D Brain model shows how the herpes virus can trigger Alzheimer’s disease Scientists injected the herpes-simplex virus type 1, the strain that causes cold sores, into brain tissue and found that it caused the brain to look and act like an Alzheimer’s brain. Injecting an antiviral drug was successful in reducing the spread and damage.

Disease-causing bacteria can grow on hydroponic microgreen mats Salmonella enterica and Listeria monocytogenes are two bacteria that can make you sick when eating contaminated produce. It turns out, some microgreen grow mats might be a breeding ground for these bacteria.

Salmonella enterica and Listeria monocytogenes are two diarrhea-causing bacteria that can make you sick when eating contaminated produce. It turns out, soil-free growing mats used to produce microgreens might be a breeding ground for these bacteria. Peat or coco coir might be a safer choice.

Muscles lost in our adult primate ancestors still appear in humans A review of previous anatomy studies found that some “ancient” muscles that are normally present in other primate species may be more common in humans than previously thought

What can microbes teach us about life in extreme environments? Microbes living in an extreme environment hosted by a rock called serpentinite use a variety of sulfur compounds to gain energy and survive, which has implications for life that might exist elsewhere in our Universe.

Microbes on Earth have adapted to survive in some pretty extreme locations. The extreme dryness of deserts, high salinity in salt deposits, cold temperatures of glaciers, and even high pressures of the deep ocean don’t stop some life forms. Another extreme environment is created by a rock known as serpentinite. This…
