Ocean microbes team up brilliantly to gather food when it's scarce

What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients—nitrogen, phosphorus, or iron—to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. And the stakes are high: Marine microbial communities drive many of the elemental cycles that sustain all life on Earth.

Largest fire grows, forces evacuation of wildlife station

The nation's largest wildfire torched more dry forest in Oregon and forced the evacuation of a wildlife research station Monday as firefighters had to retreat from the flames for the ninth consecutive day due to erratic and dangerous fire behavior.

What the latest Pegasus spyware leaks tell us

Over the weekend, a consortium of international news outlets published their findings from an investigation into the use of Pegasus, the marquee spyware of secretive billion-dollar Israeli surveillance company NSO group.  The reports from the Guardian, the Washington Post, and 15 other media organizations, are based on a leak of tens of thousands of phone numbers that appear to have been...

New study examines commuter characteristics and traffic pollution exposure among commuters

New research examines commuter characteristics to better understand how factors such as departure time, frequency, and commute length are associated with exposure to air pollution. Using personal air pollution monitors, the research clustered commuters to determine whether these clusters were associated with traffic pollution exposures. The study reveals that commuters that travel during rush hour...

Novel autoantibody adds fuel to COVID-19 'firestorm' of inflammation, blood clots

Researchers have discovered another functional autoantibody in COVID-19 patients that contributes to the disease's development and the 'firestorm' of blood clots and inflammation it induces. The autoantibody makes it much harder for the body to degrade neutrophil extracellular traps, the toxic webs of DNA and proteins produced by overactive immune cells at heightened levels in COVID patients.

Using archeology to better understand climate change

Throughout history, people of different cultures and stages of evolution have found ways to adapt, with varying success, to the gradual warming of the environment they live in. But can the past inform the future, now that climate change is happening faster than ever before?

Why NASA should visit Pluto again

In 1930, Clyde Tombaugh, a 25-year-old amateur astronomer, spied a small, dim object in the night sky.   He’d been working at the Lowell Observatory in Flagstaff, Arizona, for about a year when he used a blink comparator—a special kind of microscope that can examine and compare images—to glimpse what was for a time considered to be the ninth planet in our...
