Aging rewires RNA production, favoring short genes over long neuronal ones‎

A new Northwestern Medicine study published in the Proceedings of the National Academy of Sciences has explored the impacts of aging on essential cellular processes, findings that could shape the development of future anti-aging therapeutic strategies. Ali Shilatifard, Ph.D., the chair and Robert Francis Furchgott Professor of Biochemistry and Molecular Genetics, was the senior author of the study.

The secret life of roots: How plants fight back against salty soils‎

To people, salt is a kitchen staple. But to crops, too much of it can be devastating. Across coastal regions and irrigated agricultural land, salt is accumulating in soils, making it harder for plants to absorb water and reducing harvests. Scientists estimate that around half of the world's irrigated farmland is now affected by salinity to some degree.

Quantum material opens new path for studying unusual electronic behavior‎

By combining approaches from two rapidly growing fields of quantum physics, researchers at Penn State and Saint Louis University have demonstrated that a novel specialized material can naturally enable a new way to study unusual physical phenomena known as non-Hermitian dynamics.

Heat waves: Why British trees are shedding branches and dying‎

If you visit the Royal Botanic Gardens at Kew, on the edge of London, you will see a brightly painted skeleton of a dead oak tree. The tree, known as the climate-changed oak, succumbed in the heat wave of 2022. Instead of removing it, Kew left it in place as a reminder that climate change is already taking its toll on Britain's trees.

Sensors detect California cliff collapses hours to days before failure, report says‎

Following a four-year study, scientists at UC San Diego's Scripps Institution of Oceanography released a new report to determine whether an early warning system could detect a landslide before it happens. The "California Coastal Landslide Early Warning Research" report found that a network of in-ground sensors can provide a reliable warning of impending, dangerous landslides with hours to days' notice, but that more work is needed to formalize the findings into an actionable warning system.

Newly identified 'saprotropism' helps roots avoid decaying plant matter—but not animal decay‎

Decaying matter shapes life in soil, but it can also create hostile zones for growing roots. Professor Jiří Friml of the Institute of Science and Technology Austria (ISTA) and international collaborators have now identified "saprotropism," a root response that guides plants away from decaying plant-derived matter—but not animal-derived decay.

Mouse found near 7,000 meters may rewrite limits of mammal survival‎

A tiny mouse living nearly 7,000 meters (23,000 feet) above sea level in the Andes is helping scientists rethink the limits of life on Earth. The animal, a leaf-eared mouse, is the focus of a new international study co-authored by McMaster University researchers, revealing how mammals can survive in conditions once thought uninhabitable.

UK sets record for number of days over 34°C‎

The UK on Thursday experienced its eighth day in 2026 with the mercury climbing above 34°C (94°F), the Met Office said, breaking the previous record by one day.
