Skull specializations allow bats to feast on their fellow vertebrates

Skull of a fish-eating bat.

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.

UW conservationists celebrate new protected areas for Argentine penguins

Adult Magellanic penguin and two chicks begging.

On Dec. 3, the legislature for Argentina’s Chubut province established a new marine protected area off Punta Tombo, which would help preserve the feeding grounds for about 500,000 Magellanic penguins that make their home along this rocky stretch of Argentine coast. This is welcome news for the UW scientists who have studied these penguins for decades and advocated for their conservation.

Trees either hunker down or press on in a drying and warming western U.S. climate

Trembling aspen.

Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.

UW team programs solitary yeast cells to say ‘hello’ to one another

UW researchers have produced cell-to-cell communication in baker's yeast, a first step in learning to build multicellular organisms from scratch. The red yeast cells have been engineered to produce the plant hormone auxin, which "tells" the green cells to express a gene differently.

Shrub growth decreases as winter temps warm up

Campbell Island, New Zealand, hillside covered with the shrub Dracophyllum.

Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted by temperatures warm enough to trigger growth.

Side view of manata ray swimmming

Dried filters from the mouths of filter-feeding rays started appearing in apothecary shops in recent years, but there’s been no way to know which of these gentle-natured rays was being slaughtered. Now scientists have discovered enough differences to identify the giant manta and eight devil rays using the dried filters.
