Improve grades, reduce failure – undergrads should tell profs ‘Don’t lecture me’

A significantly greater number of students fail science, engineering and math courses that are taught lecture-style than fail in classes incorporating so-called active learning that expects them to participate in discussions and problem-solving beyond what they’ve memorized.

Active learning also improves exam performance – in some cases enough to change grades by half a letter or more so a B-plus, for example, becomes an A-minus. (more…)

Army drug users twice as likely to use synthetic marijuana as regular marijuana

Social work researchers from the University of Washington have found that among a group of active-duty Army personnel who use illicit drugs, the most abused substance is synthetic marijuana, which is harder to detect than other drugs through standard drug tests. (more…)

Amphibians in a vise: Climate change robs frogs, salamanders of refuge

By hightailing it to nearby ponds and shallow waterways, frogs and salamanders have – until now – had a way to evade exotic trout introduced to the West’s high-mountain lakes for recreational fishing.

A warming climate, however, will dry up some of the places where amphibians and their young have found refuge. Researchers in the May 1 issue of Frontiers in Ecology and the Environment write about this challenge and a novel combination of tools that could help land managers, biologists, fishing enthusiasts and other citizens weigh where amphibians are in the most need of help and guide plans for possible fish removals from selected lakes.

Automated age-progression software lets you see how a child will age

It’s a guessing game parents like to ponder: What will my child look like when she grows up? A computer could now answer the question in less than a minute.

University of Washington researchers have developed software that automatically generates images of a young child’s face as it ages through a lifetime. The technique is the first fully automated approach for aging babies to adults that works with variable lighting, expressions and poses. (more…)

UW startup creates underwater robotics with a human touch

It should be just as easy to use a robotic arm as it is to use your own hand. That’s the thinking behind University of Washington startup BluHaptics, which is taking telerobotics — controlling robots from a distance — to a new level: underwater.

Using technology developed by Howard Chizeck’s lab in the Department of Electrical Engineering, a team of UW scientists and engineers working at the Applied Physics Laboratory is creating a control system for underwater remotely operated vehicles, or ROVs. (more…)

Scientists build thinnest-possible LEDs to be stronger, more energy efficient

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient.

University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics. The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows. (more…)

Vitamin water: Measuring essential nutrients in the ocean

The phrase, ‘Eat your vitamins,’ applies to marine animals just like humans. Many vitamins are elusive in the ocean environment.

University of Washington researchers used new tools to measure and track B-12 vitamins in the ocean. Once believed to be manufactured only by marine bacteria, the new results show that a whole different class of organism, archaea, can supply this essential vitamin. The results were presented Feb. 24 at the Ocean Sciences meeting in Honolulu. (more…)
