Immune cells consult with neighbors to make decisions
Scientists and physicians have long known that immune cells migrate to the site of an infection, which individuals experience as inflammation — swelling, redness and pain. Now, researchers at the University of Washington and Northwestern University have uncovered evidence that this gathering is not just a consequence of immune activation. Immune cells count their neighbors before deciding whether or not the immune system should kick into high gear.

Polar bears in Baffin Bay skinnier, having fewer cubs due to less sea ice
Satellite tracking of adult females and visual monitoring of polar bears in Baffin Bay show changes from the 1990s to the period from 2009 to 2015. Bears in Baffin Bay are getting thinner and adult females are having fewer cubs than when sea ice was more available.

First-of-its-kind hydrogel platform enables on-demand production of medicines and chemicals
A team of chemical engineers has developed a new way to produce medicines and chemicals and preserve them using portable “biofactories” embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor’s offices or even basic refrigeration makes it hard to…

Tiny, ancient meteorites suggest early Earth’s atmosphere was rich in carbon dioxide
Tiny meteorites that fell to Earth 2.7 billion years ago suggest that the atmosphere at that time was high in carbon dioxide, which agrees with current understanding of how our planet’s atmospheric gases changed over time.

Mosquitoes are drawn to flowers as much as people — and now scientists know why
Despite their reputation as blood-suckers, mosquitoes actually spend most of their time drinking nectar from flowers. Scientists have identified the chemical cues in flowers that stimulate mosquitoes’ sense of smell and draw them in. Their findings show how cues from flowers can stimulate the mosquito brain as much as a warm-blooded host — information that could help develop less toxic repellents and better traps.

Mobile protected areas needed to preserve biodiversity in the high seas
Leaders are updating the laws for international waters that apply to most of the world’s ocean environment. This provides a unique opportunity, argues a UW Bothell marine scientist, to anticipate new techniques that allow protected zones to shift as species move under climate change.

‘The blob,’ food supply squeeze to blame for largest seabird die-off
When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”

Fisheries management is actually working, global analysis shows
Nearly half of the fish caught worldwide are from stocks that are scientifically monitored and, on average, are increasing in abundance. Effective management appears to be the main reason these stocks are at sustainable levels or successfully rebuilding, according to a new study led by the University of Washington.

Life could have emerged from lakes with high phosphorus
Life as we know it requires phosphorus, which is scarce. So, how did a lifeless environment on the early Earth supply this key ingredient? A new UW study, published Dec. 30 in the Proceedings of the National Academy of Sciences, finds an answer to this problem in certain types of carbonate-rich lakes.

Resident orcas’ appetite likely reason for decline of big Chinook salmon
Large, old Chinook salmon have mostly disappeared from the West Coast. A new University of Washington and NOAA study points to the recent rise of resident killer whales, and their insatiable appetite for large Chinook salmon, as the main driver behind the decline of the big fish.

Astronomy fellowship demonstrates effective measures to dismantle bias, increase diversity in STEM
Joyce Yen — director of the University of Washington’s ADVANCE Center for Institutional Change, an NSF-funded body to promote female STEM faculty on campus — recently worked with the Heising-Simons Foundation to dismantle bias and promote diversity in a prominent grant that the Foundation awards to postdoctoral researchers in planetary science. In this Q&A, Yen shares the many, sometimes counterintuitive ways bias can work against goals toward greater diversity, equity and inclusion in STEM fields.

New technique lets researchers map strain in next-gen solar cells
Researchers from the University of Washington and the FOM Institute for Atomic and Molecular Physics in the Netherlands have developed a way to map strain in lead halide perovskite solar cells. Their approach shows that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell, which creates small-scale defects in the grain structure, interrupts the transport of electrons within the solar cell, and ultimately leads to heat loss through a process known as non-radiative recombination.
