Simple test predicts return of bladder cancer

Scientists have devised a simple test for an earlier and more accurate warning of returning bladder cancer than existing methods, according to research(link is external) published in the British Journal of Cancer(link is external).

McMaster hosts researcher looking for ways to help pregnant women safely fight malaria

Titus Divala has seen the effects of malaria first-hand.

Now a University of Maryland researcher, he was born and raised in Malawi, where the mosquito-borne infectious disease is the third most common cause of death.

Student unfolds secrets of boreal forest moss

"Now I know mosses have a whole secret world,” says Jean, a University of Saskatchewan biology PhD student. “It’s like discovering a mini forest in the forest.” 

Not just pretty, mosses contribute up to 30 per cent of Canada’s boreal forest total growth every year, while maintaining the organic floor necessary for evergreens to grow. 

UW oceanography senior finds plastic microfibers are common on Puget Sound beaches

As the infamous floating “garbage patch” churns up bits of plastic in the tropical Pacific Ocean, a University of Washington undergraduate has discovered a related problem much closer to home: nearly invisible bits of plastic on Puget Sound beaches.

As a year-long project toward a UW bachelor’s degree, the oceanography major visited 12 beaches around Puget Sound to tally the number of microplastics, generally classified as fragments between 0.3 and 5 millimeters (1/100 to 1/5 of an inch) or smaller than a grain of rice.

First battery-free cellphone makes calls by harvesting ambient power

University of Washington researchers have invented a cellphone that requires no batteries — a major leap forward in moving beyond chargers, cords and dying phones. Instead, the phone harvests the few microwatts of power it requires from either ambient radio signals or light.

The team also made Skype calls using its battery-free phone, demonstrating that the prototype made of commercial, off-the-shelf components can receive and transmit speech and communicate with a base station.

Energy-efficient accelerator was 50 years in the making

With the introduction of CBETA, the Cornell-Brookhaven ERL Test Accelerator, Cornell University and Brookhaven National Laboratory scientists are following up on the concept of energy-recovering particle accelerators first introduced by physicist Maury Tigner at Cornell more than 50 years ago.

CBETA tests two energy-saving technologies for accelerators: energy recovery and permanent magnets. An energy recovery linac (ERL) like CBETA reclaims the energy of a used electron beam instead of dumping it after the experiment. The recovered energy is used to accelerate the next beam of particles, creating a beam of electrons that can be used for many areas of research. The beams are accelerated by Superconducting Radio Frequency (SRF) units, another energy-efficient technology pioneered at Cornell.

Global Warming May Cause Bees to Mistime Spring Emergence, Missing Their Food Supply

If it’s all in the timing, then climate change may spell problems for bees. Scientists have found that global warming may cause temporal mismatches between bees and the plant species on which they depend for food.

As Seas Rise, Tropical Pacific Islands Face a Perfect Storm

Among the places expected to be most hard-hit by sea level rise in the coming century or two are the islands of the tropical Pacific Ocean, ranging from sparsely developed archipelagos in Micronesia to heavily populated coastal areas on the Hawaiian Islands, such as Honolulu. 

Surveying sea floor animals for offshore renewable energy

There is growing interest in developing offshore wind and wave energy facilities in the Pacific Northwest. But not much is known about the sediment and animal life along the sea floor in the region.

Rising temperatures are curbing ocean's capacity to store carbon

If there is anywhere for carbon dioxide to disappear in large quantities from the atmosphere, it is into the Earth’s oceans. There, huge populations of plankton can soak up carbon dioxide from surface waters and gobble it up as a part of photosynthesis, generating energy for their livelihood. When plankton die, they sink thousands of feet, taking with them the carbon that was once in the atmosphere, and stashing it in the deep ocean.
