Researchers at the University of Washington and the University of Strathclyde report that, in Willapa Bay in Washington state, the water washing over the tidal flats during high tides is largely the same water that washed over the flats during the previous high tide. This “old” water has not been mixed in with “new” water from deeper parts of the bay or the open Pacific Ocean, and has different chemical and biological properties, such as lower levels of food for creatures within the tide flats.
A team, led by researchers at the University of Washington, has discovered how the female mosquito brain integrates visual and olfactory signals to identify, track and hone in on a potential host for her next blood meal: After the mosquito’s olfactory system detects certain chemical cues, the mosquito uses her visual system to scan her surroundings for certain shapes and fly toward them, presumably associating those shapes with potential hosts.
Old myths state that, during the time of the dinosaurs, mammals and their relatives were small and primitive. But new research shows that, during the time of the dinosaurs, mammals and their relatives actually underwent two large ecological radiations, diversifying into climbing, gliding and burrowing forms with a variety of diets.
Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska’s most productive salmon populations, and the fisheries they support, depend on the entire watershed.
In a paper published May 2 in Nature Communications, a University of Washington team reports that two major forces have shaped bat skulls over their evolutionary history — echolocation and diet — generating a huge diversity of skull shapes across 1,300 bat species today.
A new study published April 30 in the Proceedings of the National Academy of Sciences identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.
The UW Information School is taking a leading role in helping people better navigate this era of increasing online fakery and falsehood. On March 19, the school will welcome 200-some Seattle-area high school students for “MisInfo Day,” a daylong workshop on how to navigate the misinformation landscape, from Jevin West and Carl Bergstrom, the faculty duo behind “Calling BS in the Age of Big Data.”
A new website from the UW’s Jevin West and Carl Bergstrom, the duo behind the popular “Calling BS” class, asks viewers to choose which of two realistic face photos is real and which is a complete fake.
Researchers at the University of Washington 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.
Scientists have just discovered a dinosaur relative that lived in Antarctica 250 million years ago. The iguana-sized reptile’s genus name, Antarctanax, means “Antarctic king.”
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 University of Washington 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.
As the year comes to a close and festivities abound, some UW faculty creations can make great gifts for the thinking Dawg on your giving list.
In 2016, Seattle Public Schools pushed back the start times for the district’s 18 high schools by 55 minutes, from 7:50 a.m. to 8:45 a.m. And as hoped, teenagers used the extra time to sleep in.
Researchers from the University of Washington have shown how Magellanic penguins fare during the winter months when they spend months at sea feeding. They have discovered that oceanographic features are more likely to negatively impact the body conditions of Magellanic penguin females, but not males, when the penguins return to their nesting grounds in spring.
Pablo García Borboroglu, president of the Global Penguin Society and a UW affiliate associate professor of biology, has won the Whitley Gold Award and the National Geographic/Buffett Award for Leadership in Conservation, as well as accolades from the Argentine National Congress, for his research and advocacy for penguin conservation.
When levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves. Now two University of Washington scientists have shown that this reaction by plants will actually worsen climate change by making the global “carbon sink” contributed by plants was less productive.
For angiosperms — or flowering plants — one of the most important decisions facing them each year is when to flower. It is no trivial undertaking. To flower, they must cease vegetative growth and commit to making those energetically expensive reproductive structures that will bring about the next generation. Knowledge of this process at the cellular level is critical for understanding how plants allocate resources and produce the components we care most about — including the grains, tubers, leaves, nuts…
The international trade in elephant ivory has been illegal since 1989, yet African elephant numbers continue to decline. In 2016, the International Union for Conservation of Nature cited ivory poaching as a primary reason for a staggering loss of about 111,000 elephants between 2005 and 2015 — leaving their total numbers at an estimated 415,000. For media Download soundbites, b-roll and images In a paper published Sept. 19 in the journal Science Advances, an international team led by scientists at…
The University of Washington today opened the doors to a new Life Sciences Building that will transform learning, teaching and research for generations.
The $171 million Life Sciences complex includes seven floors and 207,000 square feet that encourages and makes possible team-oriented science. Designed by Perkins+Will and built by Skanska, the building encompasses a 187,000-square-foot research and teaching facility and a 20,000-square-foot research greenhouse with UW plant collections.
In a paper published April 5 in the journal Endangered Species Research, scientists at the University of Washington announced that, for a Galápagos penguin, beak size is nearly a perfect indicator of whether a bird is male or female.
A new analysis suggests the value of structured research programs for undergraduates extends to society as a whole by encouraging participants to seek advanced degrees in scientific and technological fields.
With the grand opening of the new $171 million Life Sciences Building just months away, it’s time to fill the building with faculty. That was the idea behind a $3 million Washington Research Foundation (WRF) grant to hire four biology professors. It’s called a cluster hire and will help maintain the University of Washington’s leading reputation in primary research and life sciences.
If an entire forest dies, new research shows, it has ricocheting effects in the atmosphere that can affect vegetation on the other side of the country.
New research in plants shows that a gene called MUTE is required for the formation of stomata — the tiny pores that are critical for gas exchange, including releasing the oxygen gas that we breathe.
A University of Washington professor has been awarded the prestigious Albert Schweitzer Medal for his work for developing noninvasive tools for monitoring human impacts on wildlife. Samuel K. Wasser was honored in a ceremony in Washington, D.C., Tuesday evening. The award was presented by Washington Sen. Maria Cantwell.
A University of Washington-led project spanning countries, years and institutions has attempted to reconstruct what the southern end of the world looked like during the Triassic period, 252 to 199 million years ago.
High-speed recordings of Egyptian fruit bats in flight show that instead of using a primitive form of echolocation, these animals actually use a technique recently developed by humans for surveillance and navigation.
In a published Jan. 25 in Current Biology, University of Washington researchers report that mosquitoes can learn to associate a particular odor with an unpleasant mechanical shock akin to being swatted. As a result, they’ll avoid that scent the next time.
By developing a synthetic version of the plant hormone auxin and an engineered receptor to recognize it, University of Washington biology professor Keiko Torii and her colleagues are poised to uncover plants’ inner workings, raising the possibility of a new way to ripen fruits such as strawberries and tomatoes.
A small group of fishes — possibly the world’s cleverest carnivorous grazers — feeds on the scales of other fish in the tropics. A team led by biologists at the University of Washington’s Friday Harbor Laboratories is trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior.
Kim Nasmyth, a professor of biochemistry at the University of Oxford and former postdoctoral researcher at the University of Washington, is one of five recipients of the 2018 Breakthrough Prize in Life Sciences. Nasmyth and other prize recipients were honored by the Breakthrough Prize Foundation at a ceremony December 3 at NASA’s Ames Research Center in Mountain View, California.
An unseasonably warm, dry summer on Mount Rainier in 2015 caused subalpine wildflowers to change their bloom times and form ‘reassembled’ communities, with unknown consequences for species interactions among wildflowers, pollinators and other animals.
It has become an almost essential element of academic life, from college lecture halls to elementary classrooms: the group assignment. Dreaded by some, loved by others, group projects typically aim to build teamwork and accountability while students learn about a topic. But depending on the assignment and the structure of the groups, a project can turn out to be a source of great frustration — for instructor and students alike — or the highlight of the school year. Now…
A $2.5 million National Science Foundation grant will daylight thousands of specimens from their museum shelves by CT scanning 20,000 vertebrates and making these data-rich, 3-D images available online to researchers, educators, students and the public. The University of Washington is a partner institution contributing most of the fish and bat scans.
Starting Aug. 12, the public can watch fossil preparation of the University of Washington Burke Museum’s Tyrannosaurus rex skull “live.”
A multi-year survey of the nutritional, physiological and reproductive health of endangered southern resident killer whales suggests that up to two-thirds of pregnancies failed in this population from 2007 to 2014. The study links this orca population’s low reproductive success to stress brought on by low or variable abundance of their most nutrient-rich prey, Chinook salmon.
A new study published May 30 in the Journal of Mammalogy describes a newly discovered third species of flying squirrel in North America — now known as Humboldt’s flying squirrel, or Glaucomys oregonensis. It inhabits the Pacific Coast region of North America, from southern British Columbia to the mountains of southern California.
A research team led by University of Washington biology professor Dee Boersma reports that fully grown Galapagos penguins who have fledged — or left the nest — continue to beg their parents for food. And sometimes, probably when the bounty of the sea is plentiful, parents oblige and feed their adult offspring.
