Superconducting nanowire single-photon detectors: Next big thing in blood flow measurement

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for measuring cerebral blood flow. Diffuse correlation spectroscopy (DCS), a method gaining popularity, involves the illumination of tissues with near-infrared laser rays. The light is scattered by the movement of red blood cells and the resulting pattern formed is analyzed by a detector to determine blood flow.

Nutrient-rich human waste poised to sustain agriculture, improve economies

The future connection between human waste, sanitation technology and sustainable agriculture is becoming more evident. According to research directed by University of Illinois Urbana-Champaign civil and environmental engineering professor Jeremy Guest, countries could be moving closer to using human waste as fertilizer, closing the loop to more circular, sustainable economies.

Female and young walruses depend on disappearing Arctic sea ice for food sources

A new study shows that disappearing sea ice is a significant element of the food web supporting female walruses and their dependent young in the Arctic's Chukchi Sea. Researchers were able to trace biomarkers that are unique to algae growing within sea ice to connect marine mammals with a food source that is rapidly diminishing in the face of climate change.

Effect of 'eddy killing' in oceans is no longer a matter of guesswork

Ocean currents, propelled by kinetic energy from the wind, are the great moderators of our climate. By transferring heat from the equator to polar regions, they help make our planet habitable.

Study suggests solutions to criminal justice involvement among people experiencing homelessness, serious mental illness

Nearly 60 percent of people experiencing both homelessness and serious mental illness in Metro Vancouver have had a criminal conviction, according to a new study from Simon Fraser University.

Rivers are largest global source of mercury in oceans

The presence of mercury in the world's oceans has ramifications for human health and wildlife, especially in coastal areas where the majority of fishing takes place. But while models evaluating sources of mercury in the oceans have focused on mercury deposited directly from the atmosphere, a new study led by Peter Raymond, professor of ecosystem ecology at the Yale School of the Environment and published in Nature Geoscience shows that rivers are actually the main source of the toxic heavy metal along the world's coasts.

Study identifies patterns in bird-plane collisions

Worldwide, the cost of bird collisions with planes has been estimated at $1.2 billion per year. But information on bird movements throughout the year can help avoid damage to aircraft and risk to passengers. Scientists from the Cornell Lab of Ornithology and partners have been looking for patterns in bird strike data from three New York City area airports. Their findings were published today in the Journal of Applied Ecology.
