The annual Antarctic ozone hole reached an average area of 8.9 million square miles (23.2 million square kilometers) between Sept. 7 and Oct. 13, 2022. This depleted area of the ozone layer over the South Pole was slightly smaller than last year and generally continued the overall shrinking trend of...
Revolutionary technique to generate hydrogen more efficiently from water
Researchers have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas -- an element crucial to many industrial processes. The team found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water...
High-res maps of entire polar regions provide new clues for climate researchers
A team of researchers has released four more years of high-resolution imagery data, which has been added to eight years of previous data, to create the most detailed polar region terrain maps ever created.
‘Forever chemicals’ persist through wastewater treatment, may enter crops
PFAS (per-and polyfluoroalkyl substances) persist through wastewater treatment at levels that may impact the long-term feasibility of 'beneficial reuse of treated wastewater,' according to a new study.
Does Traffic-Related Air Pollution Increase Risk of Dementia?
Higher exposure to a certain type of traffic-related air pollution called particulate matter may be linked to an increased risk of dementia, according to a meta-analysis published in the October 26, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology.
As Sea Ice Retreats, Narwhals Are Changing Their Migration Patterns
Narwhals are changing their migration patterns in response to pressure from changing Arctic climates, a new UBC report has found.
Fighting tumors with magnetic bacteria
Researchers are planning to use magnetic bacteria to fight cancerous tumors. They have now found a way for these microorganisms to effectively cross blood vessel walls and subsequently colonize a tumor.
Neuroimaging study reveals functional and structural brain abnormalities in people with post-treatment Lyme disease
In a study using specialized imaging techniques, researchers report distinctive changes in the 'white matter' and other brain tissue physiology of those with post-treatment Lyme disease, a condition affecting 10% to 20% of the nearly half a million Americans who contract Lyme disease annually.
Report by OSU, International Scientists Says Earth is ‘Unequivocally’ in Midst of Climate Emergency
An international coalition of researchers says in a report published today that the Earth’s vital signs have worsened to the point that “humanity is unequivocally facing a climate emergency.”
Sensor disguised as a sea turtle egg allows conservationists to remotely predict nest hatching time
A new low-cost sensor designed to resemble a sea turtle egg enables scientists to monitor nests remotely and predict when hatchlings will emerge almost to the day -- providing valuable information for conservation efforts and turtle nest management.
