Engineering lecture series focuses on engineering for social good

This fall, the University of Washington’s annual engineering lecture series will feature three College of Engineering faculty whose research is accelerating positive impact here and around the world.

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.

Burst of morning gene activity tells plants when to flower

Arabidopsis thaliana plants flowering outside under natural light.

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…

A University of Washington study finds that 18-month-old toddlers conduct a form of cost-benefit analysis, making choices based on how much effort they want to expend, or on whether they like the people involved.

DNA testing of illegal ivory seized by law enforcement links multiple ivory shipments to same dealers

African elephants examining a bone from another elephant

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….

Shift in large-scale Atlantic circulation causes lower-oxygen water to invade Canada’s Gulf of St. Lawrence

Rapid deoxygenation in the Gulf of St. Lawrence is caused by shifts in two of the ocean’s most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.

Climate change projected to boost insect activity and crop loss, researchers say

In a paper published Aug. 31 in the journal Science, a team led by scientists at the University of Washington reports that insect activity in today’s temperate, crop-growing regions will rise along with temperatures. Researchers project that this activity, in turn, will boost worldwide losses of rice, corn and wheat by 10-25 percent for each degree Celsius that global mean surface temperatures rise.

Hack week: Study supports collaborative, participant-driven approach for researchers to learn data science from their peers

Scientists working together on computer projects.

A team from the University of Washington, New York University and the University of California, Berkeley has developed an interactive workshop in data science for researchers at multiple stages of their careers. The course format, called “hack week,” blends elements from both traditional lecture-style pedagogy with participant-driven projects.

Bus battle: Do private shuttles affect the reliability of public transit?

a bus on the street stopped at a bus stop

Last year, King County Metro and the Seattle Department of Transportation started a pilot program that allowed Microsoft’s and Seattle Children’s Hospital’s private shuttles to pick up employees at a few public bus stops throughout Seattle. Now a recent study from researchers at the University of Washington suggests that public buses are unaffected by private shuttles most of the time.

Alexa, be my friend: Children talk to technology, but how does it respond?

When young children talk to voice-activated technologies, the devices don’t always respond in a helpful way. A new University of Washington study suggests that these interfaces could be designed to be more responsive – repeating or prompting the user, for example – and be more useful to more people.
