Planetary ‘runaway greenhouse’ more easily triggered, research shows
It might be easier than previously thought for a planet to overheat into the uninhabitable “runaway greenhouse” stage, according to new research.
Natural affinities – unrecognized until now – may have set stage for life to ignite
It might not have been just happenstance that caused components of RNA and the earliest “cell” membranes to be in the right place at the right time to spark life.

Pain of artificial legs could be eased by real-time monitoring
University of Washington engineers have developed a device that tracks how much a person’s limb swells and shrinks when inside a prosthetic socket. The data could help doctors and patients predict how and when their limbs will swell, which could be used to build smarter sockets.

Geochemical ‘fingerprints’ leave evidence that megafloods eroded steep gorge
For the first time, scientists have direct geochemical evidence that the 150-mile long Tsangpo Gorge, possibly the world’s deepest, was the conduit by which megafloods from glacial lakes, perhaps half the volume of Lake Erie, drained catastrophically through the Himalayas when their ice dams failed during the last 2 million years.

Nighttime heat waves quadruple in Pacific Northwest
Nighttime heat waves — events where the nighttime low is unusually hot for at least three days in a row — are becoming more common in western Washington and Oregon.

UW launches record 17 startup companies
The University of Washington launched a record 17 startup companies this fiscal year.
A warmer planetary haven around cool stars, as ice warms rather than cools
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star’s light with ice and snow on the planet’s surface.

Eye-tracking could outshine passwords if made user-friendly
University of Washington engineers found in a recent study that the user’s experience could be key to creating an authentication system that doesn’t rely on passwords.

Ecological forces structure your body’s personal mix of microbes
Researchers hope to build a predictive model of the human microbiome to study what affects this massive biological system and to design ways to manipulate the microbiome to achieve desired clinical outcomes.

Some volcanoes ‘scream’ at ever-higher pitches until they blow their tops
Swarms of small earthquakes before a volcanic eruption can come in such rapid succession that they create a signal called harmonic tremor. A new eruption analysis from Alaska’s Redoubt Volcano shows the harmonic tremor glided to higher frequencies, then stopped abruptly just before six eruptions in 2009.

Biceps bulge, calves curve, 50-year-old assumptions muscled aside
The basics of how a muscle generates power remain the same: Filaments of myosin tugging on filaments of actin shorten, or contract, the muscle – but the power doesn’t just come from what’s happening straight up and down the length of the muscle, as has been assumed for 50 years. The rest of the force should be credited to the lattice work of filaments as it expands outward in bulging muscle – whether in a body builder’s buff biceps or the calves of a sinewy marathon runner.
Link between low vitamin D blood levels and heart disease varies by race
Low vitamin D levels are linked to higher risk of heart disease in whites and Chinese, but not in blacks or Hispanics. The findings underscore the importance of designing medical research that includes a diverse ethnic and racial makeup of participants.
