The 91̽»¨, the Pacific Northwest National Laboratory and Microsoft Quantum announced this week that they have joined forces in a new coalition, the Northwest Quantum Nexus, to bring about a revolution in quantum research and technology.

On March 5, the CERN research board approved a new experiment at the Large Hadron Collider in Geneva to search for evidence of fundamental dark matter particles. 91̽»¨scientists are part of this endeavor, the Forward Search Experiment — or FASER — which seeks to answer one of the outstanding questions in particle physics: What is dark matter made of?

In a paper published Feb. 25 in the journal Nature, a 91̽»¨-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.

Researchers at the 91̽»¨ 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.

The Zwicky Transient Facility, based at the Palomar Observatory, has identified over a thousand new objects and phenomena in the night sky, including more than 1,100 new supernovae and 50 near-Earth asteroids. 91̽»¨ scientists are part of the ZTF team and led the development of the collaboration’s alert system, which informs science teams of possible new objects or changes to known objects in the sky.

Three teams led by 91̽»¨ researchers — Scott Dunham, Hugh Hillhouse and Devin MacKenzie — have received competitive awards totaling more than $2.3 million from the U.S. Department of Energy Solar Energy Technologies Office for projects that will advance research and development in photovoltaic materials, which are an essential component of solar cells and impact the amount of sunlight that is converted into electricity.

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.

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.

In a paper published Jan. 2 in PLOS Biology, two scientists at the 91̽»¨ 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.

Two 91̽»¨ 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.

A 91̽»¨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.
