Tasmanian devils evolve resistance to contagious cancer

A few Tasmanian devils have started a resistance movement against a contagious cancer that has depleted their numbers. Since devil facial tumor disease was first discovered in 1996, it has wiped out about 80 percent of the Tasmanian devil population. In some places, up to 95 percent of devils (Sarcophilus harrisii) have succumbed to facial […]

California’s goby is actually two different fish

It’s official: The southern tidewater goby is a thing. And it’s chubbier and nubbier than its northern cousin. Endangered tidewater gobies live in California’s seaside lagoons. Ranging roughly the entire length of the state, the fish used to be considered one species. But a new study confirms that gobies living in Northern and Southern California […]

Jeremy Freeman seeks to simplify complex brain science

Jeremy Freeman loves clean, simple lines. To see his bent toward aesthetic minimalism, you need look no further than his spare, calm website that slowly shifts colors. In the past, this fixation with style has occasionally veered toward the extreme. In graduate school at New York University, “he decided that capital letters were ugly,” says […]

Europa spouting off again

Jupiter’s moon Europa might once again be venting water into space, further supporting the idea that an ocean hides beneath its thick shell of ice, researchers reported September 26 at a news conference. Plumes erupting from the moon’s surface, silhouetted against background light from Jupiter, appear in several images taken by the Hubble Space Telescope […]

First peek under clouds reveals Jupiter’s surprising depths

PASADENA, Calif. — Jupiter’s clouds have deep roots. The multicolored bands that wrap around the planet reach hundreds of kilometers down into the atmosphere, NASA’s Juno spacecraft reveals, providing an unprecedented peek into the giant planet’s interior. “Whatever’s making those colors and stripes still exists pretty far down,” planetary scientist Scott Bolton, head of the […]

Dragon dinosaur met a muddy end

A bizarre new birdlike dino was part of an evolutionary extravaganza at the end of the age of dinosaurs. And it was a real stick-in-the-mud, too. Construction workers blasted Tongtianlong limosus out of the Earth near Ganzhou in southern China. “They very nearly blew this thing to smithereens,” says paleontologist Stephen Brusatte of the University […]

Oyster deaths linked to ‘atmospheric rivers’

Narrow channels of moisture snaking through the atmosphere can bring storms that wreck beachfront bungalows — and leave oyster beds bare. Several of these channels, called atmospheric rivers (SN: 2/26/11, p. 20), dumped particularly heavy storms on California in early 2011. The resulting freshwater influx probably left part of the San Francisco Bay without enough […]

For three years in a row, Earth breaks heat record

For the third year running, Earth’s thermostat broke a new record: 2016 was the warmest year since record-keeping began in 1880. Spurred by climate change and heat from a monster El Niño, the global average surface temperature last year was 0.94 degrees Celsius (1.69 degrees Fahrenheit) higher than the 20th century average of 13.9° C […]

Trump administration clampdowns on research agencies worry scientists

Just days into the Trump administration, alarm bells are ringing in the scientific community amid confusing and whiplashing reports of gag orders and funding freezes at the Environmental Protection Agency, the U.S. Department of Agriculture and other federal agencies. Various on-again, off-again directives range from putting a hold on tweeting (mostly still on) to banning […]

Artist’s amnesia could help unlock mysteries of memory

Generations of gurus have exhorted, “Live in the moment!” For Lonni Sue Johnson, that’s all she can do. In 2007, viral encephalitis destroyed Johnson’s hippocampus. Without that crucial brain structure, Johnson lost most of her memories of the past and can’t form new ones. She literally lives in the present. In The Perpetual Now, science […]
