A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.

A powerful, long-term study adds scientific backing for global calls for conserving 30 percent of the world's ocean.

Scientists believe a stomach-specific protein plays a major role in the progression of obesity, according to new research. The study could help with development of therapeutics that would help individuals struggling with achieving and maintaining weight loss.

Five years after introducing see-through wood building material, researchers have taken it to another level. They found a way to make their composite 100 percent renewable - and more translucent - by infusing wood with a clear bio-plastic made from citrus fruit.

A pair of studies shed light on something that is typically difficult to see with the eye: respiratory aerosols. Such aerosol particles of varying sizes are a common component of breath, and they are a typical mode of transmission for respiratory viruses like COVID-19 to spread to other people and surfaces.

Researchers have developed a new technology to overcome the inefficiencies and high error rates common among next-generation sequencing techniques that have previously limited their clinical application.

Despite increased use of repetitive transcranial magnetic stimulation in psychiatry, the rates at which patients respond to the therapy and experience remission of often-disabling symptoms have been modest at best. Now, a team of psychiatrists and biomedical engineers applied an emerging functional neuroimaging technology, known as diffuse optical tomography (DOT), to better understand how rTMS...

New research sheds light on how ancient giant crocodiles changed their diet as they matured.

Scientists have shed light on why some people who have a stroke do not also have abnormal heart rhythms, even though their hearts contain similar scar tissue.

You know that raw overwhelm people have been reporting after months of a pandemic, compounded by economic issues and social unrest? Does fatigue and compulsive social media scrolling strike a familiar chord?

Researchers have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team's printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility.

In a study proving feasibility, researchers showed that their testing technology can accurately distinguish between a viral and a bacterial infection for respiratory illness - a critical difference that determines whether antibiotics are warranted. And, importantly, the test provided results in under an hour.

Scientists demonstrated that TBI biomarkers were elevated among law enforcement and military personnel, including those without a diagnosed brain injury or concussion, repeatedly exposed to low level blast. Repeated exposure have been linked to a series of reported symptoms such as headaches, fatigue, dizziness, memory difficulties, and tinnitus. Researchers hope these data are the first step to...

A new auroral phenomenon discovered a year ago is probably caused by areas of increased oxygen atom density occurring in an atmospheric wave channel. The speculative explanation offered by the researchers gained support from a new study.

Giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants - the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected in virtually all ecosystems. But how dangerous are the smallest of them, so-called nanoplastics?

Scientists have uncovered potentially dangerous chemical pollutants that are released from disposable face masks when submerged in water. The research reveals high levels of pollutants, including lead, antimony, and copper, within the silicon-based and plastic fibres of common disposable face masks.

By using silicone polymers, scientists have made the softest brain implant to date with the thickness of a thin sewing thread (~0.2 mm), and the consistency of soft pudding - as soft as the brain itself. They were then able to implant it into the brain using a trick from a cookbook.

A new paper suggests that unconscious biases in the health care system may have influenced how individuals with intellectual disabilities were categorized in emergency triage protocols.

Pyrosomes spend their entire lives in the open ocean and therefore easily go unnoticed. Nevertheless, they are key components of deep-sea ecosystems. This is shown by a novel study conducted off the Cabo Verde Islands.

Researchers have developed a new method to extract metals, such as copper, from their parent ore body. The research team have provided a proof of concept for the application of an electric field to control the movement of an acid within a low permeability copper-bearing ore deposit to selectively dissolve and recover the metal in situ.

A new study suggests that over the past 30 years, there has been little to no increase in the association between adolescents' technology engagement and mental health problems. The study also urges more transparent collaborations between academia and industry.

A new map of the Schrodinger basin of the moon could help guide future exploration missions.

Researchers have identified more than 250 'severity associated' proteins in the worst cases of COVID-19. These findings could help researchers identify the mechanisms that cause severe COVID-19.

Researchers have found that people who live beyond 105 years tend to have a unique genetic background that makes their bodies more efficient at repairing DNA, according to a new study.
