This common fish has an uncommon feature: Forehead teeth, used for mating
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.
Deep beneath the French Alps, dark matter hunters narrow their search
Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including researchers from the UW, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detector’s prototype have already ruled out one of the leading theories of how dark matter originated.

Atlantic Ocean current expected to undergo limited weakening with climate change, study finds
The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to Northern Hemisphere. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting what amounts to a near-collapse relative to the AMOC strength in observations today. But a new study from a team of researchers that included the University of Washington shows that the AMOC is likely to weaken to a much lesser extent than current projections suggest.
