UW to host first of four White House public workshops on artificial intelligence
From self-driving vehicles to social robots, artificial intelligence is evolving at a rapid pace, creating vast opportunities as well as complex challenges. Recognizing that, the White House Office of Science and Technology Policy is co-hosting four public workshops on artificial intelligence — the first of them May 24 at the University of Washington. Subsequent events…
Using static electricity, insect-sized flying robots can land and stick to surfaces
A new study co-authored by a University of Washington mechanical engineer demonstrates how flying insect-sized robots can land and stick to surfaces, which conserves energy and extends flight times.
Will more snow over Antarctica offset rising seas? Don’t count on it
Heavier snowfall over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.

US-India collaboration finds molecular signatures of severe malaria
The malaria parasite can cause unusually severe cases of the eponymous disease in patients, leading to higher mortality and poorer health outcomes among survivors. But scientists have long struggled to understand why some patients develop severe malaria. The University of Washington’s International Center of Excellence for Malaria Research in South Asia — along with partners…

Proton-conducting material found in jelly that fills organs of sharks, skates and rays

UW researchers unleash graphene ‘tiger’ for more efficient optoelectronics
In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.

Skull specializations allow bats to feast on their fellow vertebrates
Over their 52-million-year history, a few bats have evolved a taste for their fellow vertebrates. Now biologists at the University of Washington and the Burke Museum of History and Culture are shedding light on how these so-called “carnivorous bats” adapted to the daunting task of chowing down their backboned prey.

Early Earth’s air weighed less than half of today’s atmosphere
The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere. The results, published online May 9 in Nature Geoscience, reverse…

Scientists crack secrets of the monarch butterfly’s internal compass
Each fall, monarch butterflies across Canada and the United States turn their orange, black and white-mottled wings toward the Rio Grande and migrate over 2,000 miles to the relative warmth of central Mexico. This journey, repeated instinctively by generations of monarchs, continues even as monarch numbers have plummeted due to loss of their sole larval food…

To be sustainable, conservation needs to consider the human factor
The authors of a new paper in Science propose a set of social indicators that can be used to gauge how ecosystem management affects four essential factors in human lives: well-being, values, the ability to act purposefully and inequality. Considering such indicators, they note, serves not only to describe what exists but to define what is important in setting sustainability goals.
