    A new algorithm finds nearby stars that could host hidden worlds

    A new planet-hunting algorithm suggests that at least 9 percent of nearby stars could host planets orbiting out of sight — and the stars’ chemistry could help find the worlds.

    Planetary astrophysicist Natalie Hinkel of the Southwest Research Institute in San Antonio and colleagues trained a machine-learning algorithm on a catalog of thousands of stars and their chemical compositions (SN...

    Dried Earth microbes could grow on Mars with just a little humidity

    SAN FRANCISCO — Salt-loving microbes can dry out and come back to life with just a little humidity, researchers have demonstrated for the first time.

    Scientists have suspected that microbes in arid places may get their moisture from humidity alone, but no one has shown that dried-out microbes can revive with water sucked from the air. Dessicated Halomonas bacteria from Washington’s Hot...

    3-D mammograms are popular, but are they better than 2-D?

    In recent years, women getting a mammogram have had a new decision to make: 2-D or 3-D?

    Some breast-care centers have touted the newer 3-D mammography technology as more accurate. But while initial research suggests that it may be a more sensitive diagnostic test, evidence that the technology actually reduces the number of deaths from breast cancer better than 2-D imaging is lacking....

    Gut microbes might help elite athletes boost their physical performance

    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...

    Capuchin monkeys’ stone-tool use has evolved over 3,000 years

    Excavations in Brazil have pounded out new insights into the handiness of ancient monkeys.

    South American capuchin monkeys have not only hammered and dug with carefully chosen stones for the last 3,000 years, but also have selected pounding tools of varying sizes and weights along the way.

    Capuchin stone implements recovered at a site in northeastern Brazil display signs of shifts...

    The highest-energy photons ever seen hail from the Crab Nebula

    Physicists have spotted the highest-energy light ever seen. It emanated from the roiling remains left behind when a star exploded.

    This light made its way to Earth from the Crab Nebula, a remnant of a stellar explosion, or supernova, about 6,500 light-years away in the Milky Way. The Tibet AS-gamma experiment caught multiple particles of light — or photons — from the nebula with energies...

    New approaches may help solve the Lyme disease diagnosis dilemma

    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...

    Parasites ruin some finches’ songs by chewing through the birds’ beaks

    Invasive parasites in the Galápagos Islands may leave some Darwin’s tree finches singing the blues.

    The nonnative Philornis downsi fly infests the birds’ nests and lays its eggs there. Fly larvae feast on the chicks’ blood and tissue, producing festering wounds and killing over half of the baby birds. Among survivors, larval damage to the birds’ beaks may mess with the birds’ songs when...

    The cosmic ‘Cow’ may be a strange supernova

    The cosmic oddity known as the Cow may have been a dying star that shed its skin like a snake before it exploded.

    Newly released observations support the idea that the burst occurred in a dense environment with strong magnetic fields, astronomer Kuiyun Huang and colleagues report in The Astrophysical Journal Letters June 12.

    These new measurements “for the mysterious transient …...
