New study traces the marsupial origins in N. America, finds mammals during Age of Dinosaurs packed a powerful bite

an extinct mammal

A new study by paleontologists at the Burke Museum of Natural History & Culture and the University of Washington describes an early marsupial relative called Didelphodon vorax that lived alongside dinosaurs and had, pound-for-pound, the strongest bite force of any mammal ever recorded.

Answers to frequently asked questions about a 255-year-old tumor in a ‘pre-mammal.’


Fossilized evidence of a tumor in a 255-million-year-old mammal forerunner

A tumor next to a tooth.

University of Washington paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.

No peeking: Humans play computer game using only direct brain stimulation

The UW researchers used a magnetic coil placed at the back of the skull to noninvasively stimulate test subjects’ brains. Players used the absence or presence of phosphenes — blobs of light that appear when researchers stimulate a specific region of the visual cortex — to guide them through a maze without actually seeing the maze.

UW researchers have published the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation — without relying on any usual sensory cues from sight, hearing or touch.

For the first time, scientists catch water molecules passing the proton baton

water-drop-TILE

Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.

Telephone-based intervention shows promise in combating alcohol abuse among soldiers

Researchers used ads and informational booths at military events to recruit participants for the study.

Alcohol abuse is pervasive in the military, where a culture of heavy drinking and the stress of deployment lead many soldiers down a troubled path. Almost half of active-duty military members in the United States — 47 percent — were binge-drinkers in 2008, up from 35 percent a decade earlier. Rates of heavy drinking also…


Mislabeled seafood may be more sustainable, new study finds

Fish labeled red snapper seen on ice in a fish market.

A University of Washington study is the first to broadly examine the ecological and financial impacts of seafood mislabeling. The paper, published online Nov. 2 in Conservation Letters, finds that in most cases, mislabeling actually leads people to eat more sustainably, because the substituted fish is often more plentiful and of a better conservation status than the fish on the label.

UW Professor Emeritus David J. Thouless wins Nobel Prize in physics for exploring exotic states of matter

An illustration of how “heavy water” within the Sudbury Neutrino Observatory detects neutrinos from the sun.

The Royal Swedish Academy of Sciences announced Tuesday that David James Thouless, professor emeritus at the University of Washington, will share the 2016 Nobel Prize in physics with two of his colleagues. Thouless splits the prize with Professor F. Duncan M. Haldane of Princeton University and Professor J. Michael Kosterlitz of Brown University “for theoretical discoveries of topological phase transitions and topological phases of matter,” according to the prize announcement from the Academy. Half the prize goes to Thouless while Haldane and Kosterlitz divide the remaining half. Thouless is the UW’s seventh Nobel laureate, and second in physics after Hans Dehmelt in 1989.
