MicrobesAncient bacteria could persist beneath Mars’ surface
Radiation-tolerant microbes might be able to survive beneath Mars’ surface for hundreds of millions of years, a new study suggests.

MicrobesHow fungi make potent toxins that can contaminate food
Genetically engineering Aspergillus fungi to delete certain proteins stops the production of mycotoxins that can be dangerous to human health.

MicrobesHow dormant bacteria spores sense when it’s time to come back to life
Bacterial cells shut down and become spores to survive harsh environments. An internal countdown signals when it’s safe for bacteria to revive.

MicrobesMeet the fungal friends and foes that surround us
Keith Seifert’s book The Hidden Kingdom of Fungi explores how microfungi shape our world.

Health & MedicineTiny amoebas move faster when carrying cargo than without
A new study of the carrying capacity of single-celled amoebas may help scientists develop mini “trucks” to precisely target disease in the human body.

MicrobesThis giant bacterium is the largest one found yet
On average, Thiomargarita magnifica measures 1 centimeter long and maxes out at 2 centimeters. It is 50 times larger than other giant bacteria.

MicrobesNew images reveal details of two bacteria’s molecular syringes
It’s unclear exactly how these species use their tiny injectors, but learning how they work could lead to nanodevices that target specific bacteria.

LifeSome E. coli set off viral grenades inside nearby bacteria
A bacterial toxin called colibactin awakens dormant viruses embedded in bacterial DNA, but its ecological role is still unknown.

Health & MedicineFecal transplant pills helped some peanut allergy sufferers in a small trial
In a small study, a one-day fecal microbiota transplant allowed some peanut-allergic adults to safely eat one to two peanuts several months later.

LifeWhy kitchen sponges are the perfect home for bacteria
Sponges are remarkably diverse hot spots for bacteria, in part because of the mixed-housing environment that the tools offer their tenants.

MicrobesA chain mail–like armor may shield C. difficile from some antibiotics
Examining the structures that protect Clostridioides difficile from medicines could help researchers find new ways to target and kill the bacteria.

AnimalsGut microbes help some squirrels stay strong during hibernation
Microbes living in the critters’ guts take nitrogen from urea and put it into the amino acid glutamine, helping squirrels retain muscle in the winter.
