Researchers found that only a few Canadian weather stations showed an earlier start date for the outdoor skating season, while most stations experienced a decrease in its length over the past half century. Climate change is projected to end outdoor skating in areas like British Columbia and Southern Alberta within decades.
Researchers used bovine collagen to enhance gum healing around exposed roots, resulting in thicker margins and complete coverage of roots in over half the cases. The study found that the collagen acted as a scaffold for the body's own cells to repair damage, making it a possible solution for patients with limited donor tissue.
Neuroscientists at UC Berkeley and Portugal's Champalimaud Center have demonstrated that the brain can be trained to perform tasks it normally doesn't, using plasticity to master purely mental tasks. This breakthrough advances work on brain-machine interfaces, potentially leading to prosthetic devices that feel like natural movement.
Researchers used X-rays to decipher how certain natural antibiotics defy chemical rules, unlocking a mechanism that could enable scientists to synthesize many important chemicals currently found only in nature. The discovery has broad implications, as the six-membered ring is a common structural feature found in hundreds of drug molecu...
A Canadian study finds that warming of at least 2 degrees Celsius will be unavoidable in mid-to-high latitude regions, including Canada. The research uses an earth system climate model to predict that even with zero greenhouse gas emissions, the world's temperature would continue to rise by about a quarter of a degree over a decade.
Researchers at the University of Edinburgh have discovered a way to increase hepatocyte cells, which detoxify the liver, by encouraging their production instead of bile duct cells. This breakthrough could help develop drugs to encourage liver self-repair and ease pressure on waiting lists for liver transplants.
A new mathematical model reveals that hosts can gain a unique evolutionary advantage when interacting with parasites through multiple traits. This discovery may help explain how humans, plants, and animals evolve to withstand parasite attacks.
A UK study of 40,000 households found that staying out late is linked to problem behaviors like smoking and drinking among 10-15 year olds. Regularly staying out late without parental knowledge is associated with family relationships and geographical location.
Researchers have discovered a way for soil bacteria to convert an epoxide into a six-membered cyclic ether, a common structural feature in hundreds of drug molecules. This breakthrough has implications for the development of new polyether drugs and potential biosynthesis strategies.
Researchers at University of Utah designed a new game controller that vibrates and stretches the thumb tips to simulate real-world sensations. The device delivers directional cues by stretching the skin of the thumb tips in different directions.
The Houston metropolitan area has become the most ethnically diverse large metropolitan area in the country, with a significant reduction in segregation over the past 20 years. The region's diversity is attributed to changes in immigration laws in 1965, which led to a substantial shift in the population's ethnic composition.
Researchers discovered that Hydra's stinging cells are linked to primitive light-responsive cells via a nervous system, enabling the animals to react to light. This finding reveals how Hydra can hunt during the day despite lacking eyes, and hints at a common ancestor with humans.
