Arctic Ocean passed a tipping point and scientists say it may never recover
The Arctic Ocean may have crossed a dangerous tipping point. Scientists say the rapid disappearance of sea ice is triggering a hidden chemical shift that is stripping the ocean of nitrate — a nutrient essential for the tiny plankton that support Arctic life. As nitrate levels plunge, the entire food...
Scottish wrens may be evolving into new species through island gigantism
Tiny birds on remote Scottish islands are undergoing a dramatic evolutionary transformation. Scientists studying four isolated populations of British Wrens discovered that some island birds have grown astonishingly large — with the biggest St Kilda Wrens weighing more than twice as much as the smallest mainland birds. The research suggests...
Scientists Reverse Brain Aging, With a Nasal Spray
New therapy is turning back the clock in aging brains, healing inflammation, restoring memory and reshaping the future of brain age-related therapies.
Vitamin K Analogues May Help Transform the Treatment of Neurodegenerative Diseases
Neurodegenerative diseases like Alzheimer’s, Parkinson’s, and Huntington’s disease are characterized by the progressive loss of neurons.
AI Speeds up Discovery of Next-gen Computer Chips and Electronic Materials
New research using an artificial intelligence (AI) system is helping to develop new gallium-based semiconductor materials much faster than traditional methods.
Humanity has already exceeded Earth’s limits, study warns
Humanity may already be living far beyond what Earth can sustainably support, according to a sweeping new study analyzing more than 200 years of population and environmental data. Researchers found that while population growth once fueled innovation and expansion, the trend shifted decades ago as the planet’s resources became increasingly...
Scientists discover ancient single-celled ancestors still live on in your blood
Scientists uncovered evidence that human blood cells may trace their origins back to single-celled ancestors that lived 700 million years ago. By rebuilding the evolutionary family tree of blood cells, the team revealed how today’s immune system grew from some of Earth’s earliest life forms.
Climate Change Weakens the Purification Function of Lakes
Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water.
Seedling Census Offers Clues to What the Future Might Hold for Michigan Forests
The history of a forest might be measured by the trunks and branches looming overhead.
