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.

Female eggs are picky and can reject a partner’s sperm Having trouble getting pregnant? Scientists have discovered a new reason behind unexplained infertility. After sex, female eggs send out chemical signals for sperm to approach or stay away. Researchers found that female eggs show no preference for their partner’s sperm compared to a random stranger.

A new way to look for signs of ancient life on Earth and Mars Scientists have found that high concentrations of rare elements might be evidence of life near ancient hot springs.

The Mars 2020 mission involves sending a rover, named Perseverance, to Mars to look for evidence of past life on that planet. Perseverance will collect samples of 3 billion year old rocks that scientists on Earth think might contain signs READ MORE

How does life handle the harshness of space? Experiments on the International Space Station showed that lichens, a combination of algae and fungi, survived in space-like, flight, and Mars-like environments.
