Southern Ontario wetlands provide $4.2 billion worth of sediment filtration and phosphorus removal services each year, keeping our drinking water sources clean and helping to mitigate harmful and nuisance algal blooms in our lakes and rivers.

Biomedical scientists have discovered a new immune pathway in chickens that viruses may be targeting. The discovery, which has implications also for diseases affecting other birds, sheds greater light on birds' immune responses to zoonotic viruses -- specifically, how those may differ from responses seen in humans.

Recent discoveries by stem cell scientists may help make cancer treatment more efficient and shorten the time it takes for people to recover from radiation and chemotherapy.

Faulty versions of the BRCA1 and BRCA2 genes are well known to increase the risk of breast cancer in men and women, and in ovarian cancer. Now BRCA1 and BRCA2 have been linked to several other cancers, including those that affect men.

A group of genes that play an essential role in building components of our cells can also impact human lifespan, finds a new study.

A novel plan that offers partnership in keeping the United States electric grid stable and reliable could be a win-win for consumers and utility operators.

Scientists and engineers discover fluorescence from silicon nanoparticles in cement and show how it can be used to reveal early signs of damage in concrete structures.

A large study conducted in England found that, compared to the general population, people who had been hospitalized for COVID-19 -- and survived for at least one week after discharge -- were more than twice as likely to die or be readmitted to the hospital in the next several months.

Researchers report that a yeast cells can actively regulate a process called phase separation in one of their membranes. During phase separation, the membrane remains intact but partitions into multiple, distinct zones or domains that segregate lipids and proteins. The new findings show for the first time that, in response to environmental conditions, yeast cells precisely regulate the temperature...

Protective coatings are common for many things in daily life that see a lot of use: we coat wood floors with finish; apply Teflon to the paint on cars; even use diamond coatings on medical devices. Protective coatings are also essential in many demanding research and industrial applications.

A novel technique that transplants a patient's own fat into the sole of their foot could offer relief to those suffering from a common and painful condition called plantar fasciitis.

Eating dinner close to bedtime, when melatonin levels are high, disturbs blood sugar control, especially in individuals with a genetic variant in the melatonin receptor MTNR1B, which has been linked to an elevated risk of type 2 diabetes. The high melatonin levels and food intake associated with late eating impairs blood sugar control in carriers of the MTNR1B genetic risk variant through a defect...

Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter.

Researchers developed and validated an artificial-intelligence-based method to evaluate patients with Stargardt, an eye disease that can lead to childhood vision loss. The method quantifies disease-related loss of light-sensing retina cells, yielding information for monitoring patients, understanding genetic causes of the disease, and developing therapies to treat it.

For the first time, researchers have created blue LEDs using layers of metal halide perovskite linked with asymmetrical bridges, solving a critical instability problem.

A physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field. This question has challenged physicists for over 100 years but a mathematical physicist has suggested an alternative approach, with controversial implications.

Lead haunts old homes in chipping paint and pipes, but it also lurks outside, in soil. It's the stuff of mud pies and garden plots, crumbling from boot treads to join household dust in forgotten corners. It's easily overlooked, but soil can be an important source of lead where children live and play.

Researchers have developed a framework that solves the challenge of bridging experimental and computer sciences to better predict peptide structures.

A protein known as Lefty pumps the brakes as human embryos begin to differentiate into the bones, soft tissues and organs that make us.

Modelling the heart in 3D using combined imaging techniques can help predict heart rhythm abnormalities, or arrhythmias, in patients with the genetic heart disease hypertrophic cardiomyopathy.

Researchers use dissipative particle dynamics simulations to examine the translational diffusion of Janus nanoparticles at the interface between two immiscible fluids. The simulations shed light on the dynamic behavior of the nanoparticles at a water-oil interface, and the work reveals a strong influence of their shape on their orientation at the interface as well as on their mobility. In theory,...

Researchers decided to explore two very different quantum problems: breaking the encryption of Bitcoin and simulating the molecule responsible for biological nitrogen fixation. They describe a tool they created to determine how big a quantum computer needs to be to solve problems like these and how long it will take.

Transfusions of blood plasma donated by people who have already recovered from infection with the pandemic virus may help other patients hospitalized with COVID-19, a new international study shows.

Researchers discovered that the chance a pathogenic genetic variant may actually cause a disease is relatively low - about 7 percent. They also found that some variants, such as those associated with breast cancer, are linked to a wide range of risks for disease. The results could alter the way the risks associated with these variants are reported, and one day, help guide the way physicians...
