TB vaccine may enable elimination of the disease in cattle by reducing its spread
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
The human brain consumes vast amounts of energy, which is almost exclusively generated from a form of metabolism that requires oxygen. While the efficient and timely delivery of oxygen is known to be critical to healthy brain function, the precise
Positive associations between premenstrual disorders and perinatal depression
Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to research published March 28 in the open access journal PLOS Medicine. The relationship works both ways: those with perinatal depression
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
Hyenas are generalist predators (and scavengers) with a broad range of prey species. They are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey
Lyrebird synchronizes elements of its mating dance

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
