Synthetic tissue can repair hearts, muscles, and vocal cords Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University develop a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in regenerative medicine. “People recovering from heart damage often face a long and tricky journey. Healing is challenging because of the…

Warning signs of sight loss could be identified before vision deteriorates A new study has shown that the signs of age related macular degeneration can set in earlier than previously thought — even before patients begin to lose their sight. …

A study led by Fernando Colchero, University of Southern Denmark and Susan Alberts, Duke University, North Carolina, that included researchers from 42 institutions across 14 countries, provides new insights into the aging theory “the invariant rate of ageing hypothesis,” which states that every species has a relatively fixed rate of…

Research has revealed a correlation between being particularly proficient in tool use and having good syntactic ability. A new study has now shown that both skills rely on the same neurological resources, which are located in the same brain region. …

Sense of smell is our most rapid warning system The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals’ survival. Using a novel technique, researchers at Karolinska Institutet in Sweden have been able to study what happens in the brain when the central nervous system judges a smell…

Allergies to mRNA-based COVID-19 vaccines rare, generally mild, study finds Allergic reactions to the new mRNA-based COVID-19 vaccines are rare, typically mild and treatable, and they should not deter people from becoming vaccinated, according to research from the Stanford University School of Medicine. The findings will be published online Sept. 17 in JAMA Network Open. “We wanted to understand the…

COVID-19 virus is evolving to get better at becoming airborne, new study shows Study suggests need for better ventilation and tight-fitting masks, in addition to widespread vaccination to help stop spread of the virus Date: September 16, 2021 Source: University of Maryland Summary: A new study finds that SARS-CoV-2 is evolving toward more efficient aerosol generation, and loose-fitting masks provide significant but only modest source control. …
