A soil fungus and a marine alga have formed a beautiful friendship.
In a lab dish, scientists grew the fungus Mortierella elongata with a photosynthetic alga called Nannochloropsis oceanica. This odd couple formed a mutually beneficial team that kept each other going when nutrients such as carbon and nitrogen were scarce, researchers report July 16 in eLife.

SlimeRuth KassingerHoughton Mifflin Harcourt, $26
A slew of popular-science books have set out to convince readers that some overlooked, obscure or generally disdained category of thing is actually wildly important, whether it’s salt, garbage or beavers (SN: 8/4/18, p. 28). Slime, all about algae, is one of those books.
If you’re skeptical that algae can sustain such an...
One difference between elite athletes and the rest of us might be in what hangs out in their guts.
Microbes that flourished in the guts of some runners after a marathon boosted the time that lab mice ran on a treadmill, researchers report June 24 in Nature Medicine. These particular microbes seem to take lactate, pumped out by muscles during exercise, and turn it into a compound that may...
In 2005, Rachel Straub was a college student returning home from a three-week medical service mission in Central America. Soon after, she suffered a brutal case of the flu. Or so she thought.
“We were staying in orphanages,” she says of her trip to Costa Rica and Nicaragua. “There were bugs everywhere. I remember going to the bathroom and the sinks would be solid bugs.” She plucked at...
Knowing your enemy is an important principle of competition, and scientists may just have become more familiar with one nasty stomach virus.
Closeup looks at several strains of norovirus reveal that the vomit- and diarrhea-inducing virus can come in a variety of sizes, researchers report online June 10 in the Proceedings of the National Academy of Sciences. Knobs studding the virus’s...
Arctic waters turn out to be teeming with some of the world’s smallest entities — viruses.
Water samples taken during a three-year expedition around the world’s oceans identified around 200,000 virus species, roughly 12 times the number found in a previous smaller survey. And 42 percent of those viruses were found exclusively in the Arctic, researchers report April 25 in Cell.

One parasite that feeds on algae is so voracious that it even stole its own mitochondria’s DNA.
Mitochondria — the energy-generating parts of cells — of the parasitic plankton Amoebophyra ceratii seem to have transferred all of their DNA to the cell’s nucleus, researchers report April 24 in Science Advances. The discovery is the first time that scientists have found an oxygen-using...

Poop contains a lot of valuable scientific information. Researchers can monitor microbes, track enzyme activity or hunt for DNA to gather clues about overall health.
There’s so much one can learn from the waste product that microbiologist Aadra Bhatt at the University of North Carolina at Chapel Hill decided there should be a word for that research — something in the same vein as “in...

Bionic microbes outfitted with tiny semiconductor components can generate useful chemicals more efficiently than normal cells.
Microorganisms like fungi are commonly used in biomanufacturing to convert simple carbon-based molecules, such as sugar, into a wide range of chemical ingredients for pharmaceuticals and other products. But much of a microbe’s carbon intake typically gets used to...
