It’s all in the twist: Physicists stack 2D materials at angles to trap particles on the nanoscale, creating a unique platform to study quantum optical physics
In a paper published Feb. 25 in the journal Nature, a University of Washington-led team of physicists report that it has developed a new system to trap individual excitons — bound pairs of electrons and their associated positive charges. Their system could form the basis of a novel experimental platform for monitoring excitons with precision and potentially developing new quantum technologies.

Playground study shows how recess can include all children
Recess, for most children, is synonymous with freedom. A break from class that has nothing to do with learning and everything to do with play. For children with autism, the playground can be an isolating experience. The spontaneous soccer games, roving packs of friends and virtual buffet of activities can be chaotic, frustrating and confusing….

Parents don’t pick favorites, at least if you’re a Magellanic penguin
Researchers at the University of Washington wanted to know how Magellanic penguin parents in South America balance the dietary demands of multiple chicks. As they report in a paper published Jan. 23 in the journal Animal Behaviour, when a Magellanic penguin parent returns to its nest with fish, the parent tries to feed each of its two chicks equal portions of food, regardless of the youngsters’ differences in age or size.

Researchers can predict childhood social transitions
A new University of Washington study suggests that the children most apt to socially transition to the gender “opposite” their sex at birth are those who already demonstrate the strongest “cross-gender” identities, and that the transitions don’t appear to alter a child’s gender identity or preferences.

Astronomers find signatures of a ‘messy’ star that made its companion go supernova
On Jan. 10 at the 2019 American Astronomical Society meeting in Seattle, an international team of astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion.

The number of single male Magellanic penguins is rising at this breeding colony. Here’s why.
Female Magellanic penguins are more likely to die at sea as juveniles, which has caused a skewed sex ratio of nearly three adult males to every female, as well as population decline of more than 40 percent since 1987 at one of their largest breeding colonies — Punta Tombo in Argentina.
How economic theory and the Netflix Prize could make research funding more efficient
In a paper published Jan. 2 in PLOS Biology, two scientists at the University of Washington and North Carolina State University use the economic theory of contests to illustrate how the competitive grant-application system has made the pursuit of research funding inefficient and unsustainable — and that alternative methods, such as a partial lottery to award grants, could relieve pressure on professors and free up time for research.

New global migration estimates show rates proportionally steady since 1990, high rate of return migration
Two University of Washington scientists have unveiled a new statistical method for estimating migration flows between countries. They show that rates of migration are higher than previously thought, but also relatively stable, fluctuating between 1.1 and 1.3 percent of global population from 1990 to 2015. In addition, since 1990 approximately 45 percent of migrants have returned to their home countries, a much higher estimate than other methods.

Underwater sensors for monitoring sea life (and where to find them)
A UW team created a mechanical eye under the ocean’s surface that could live near renewable-energy sites and use a series of sensors to watch nearby animals. On Dec. 13, the researchers put the newest version of the AMP into the waters of Seattle’s Portage Bay for two weeks of preliminary testing before a more thorough analysis is conducted in Sequim, Washington.

Farmers can already use drones to soar over huge fields and monitor temperature, humidity or crop health. But these machines need so much power to fly that they can’t get very far without needing a charge. Now, engineers at the University of Washington have created a sensing system that is small enough to ride aboard a bumblebee.
