New View into Our Guts Reveals Microbiome’s Murky Links to Health

human microbiome gut health

What is living in your gut? It might depend less on your diet, exercise habits, weight and sex than you think, according to new findings. Our health is tied to trillions of organisms that live in and on us. But the extent of their impact has only recently come into focus. And scientists are just [...]

New Extremophile Breathes Rocket Fuel

curiosity-scoops

The energetic molecule perchlorate is rocket fuel and, it turns out, food for ancient microbes. Given that deposits of the stuff have been found wherever robots look on Mars, could the chlorine compound—poisonous to the development of humans—be serving as Martian life’s lunch? A team of Dutch researchers show in the April 5 edition of [...]

Hurricane-Riding Microbes Make a Home at Cruising Altitude

microbe-culture

Sample a hurricane’s air from a plane high in the stratosphere and, in addition to the expected water and grit, you’ll find an abundance of microbes. Swept up from land and sea by the tropical cyclone’s power, the skyborne bacteria persist in the atmosphere for days—and some may even thrive there. A new survey of [...]

Millennia-Old Microbes Found Alive in Deep-Ocean Muck

mud-core

A sparse community of microbes can persist for eons in the clay beneath the deep blue sea. When scientists drilled into the Pacific Ocean bottom and pulled up a long core of clay, they also pulled up microbes living on so little that it was hard for the scientists to tell if they were alive [...]

How Going with the Flow Helped Microbes Eat BP’s Oil Spill

Microbes kept the oil and gas spewing from the Macondo well from becoming even more of a disaster, preventing the Deepwater Horizon blowout from deeply befouling the Gulf coast. But these hydrocarbon-chompers got an assist from the Gulf of Mexico—the prevailing tides and currents helped keep hydrocarbon-eating microbes on the job, according to the results [...]

Can fermenting microbes save us from climate change?

Clostridium-ljungdahlii

Just as bacteria and fungi are methodically breaking down the millions of gallons of oil spewing into the Gulf of Mexico, microbes might help us with another uncontrolled emission due to human activity—carbon dioxide. An anaerobic bacteria by the name of Clostridium ljungdahlii can ferment everything from sugars to simple mixtures of carbon dioxide and [...]

Mat of microbes the size of Greece discovered on seafloor

census of marine life microbes mat burrowers

Gargantuan whales and hefty cephalopods are typically thought of as the classic marine mammoths, but they might have to make way for the mighty microbes, which constitute 50 to 90 percent of the oceans’ total biomass, according to newly released data. These tiny creatures can join together to create some of the largest masses of [...]

Octopuses Make Food for Weird Critters

octopus feed

Along with us humans, a range of hungry hunters prey on the scrumptious octopus. The boneless octopus must avoid becoming lunch for sharks, eels, fish and even killer whales. But not all of the organisms that feed on octopuses are such charismatic megafauna. Octopuses, both dead and alive, are part of the delicate, detailed food [...]

SciArt of the Day: Fermented Fashions

12-033FEATURE

What happens when you take a bag of sweaty hockey gear and throw it in a vat of beer for a week? I’m not sure (although I’m sure this must have been tried before), but a researcher and an artist at the University of Western Australia are trying their own fermented fashion experiment. Using a [...]
