Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds. The research, led by the University of Cambridge and Penn State University, improves prospects for the elimination and

Researchers racing to develop Paxlovid replacement

Researchers from Rutgers believe they are among the leaders in a race to find an oral COVID-19 treatment to supplement or replace Paxlovid — an antiviral medication that helps keep high-risk patients out of the hospital. Their report, which will

New imaging method illuminates oxygen’s journey in the brain

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects

The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada. Microparticles from car tyres, pesticides from farmers’ fields,

Cell division quality control ‘stopwatch’ uncovered

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from

Small birds spice up the already diverse diet of spotted hyenas in Namibia

Atmospheric observations in China show rise in emissions of a potent greenhouse gas

To achieve the aspirational goal of the Paris Agreement on climate change — limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels — will require its 196 signatories to dramatically reduce their greenhouse gas

Virtual rehabilitation provides benefits for stroke recovery

A stroke often impacts a person’s ability to move their lower body from the hips down to the feet. This leads to diminished quality of life and mental health in addition to increased susceptibility to falls. But now, UBC Okanagan
