Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout‎

Geopolitical tensions in Eastern Europe underscore the urgency of addressing the climate and radiological consequences of a regional nuclear conflict. Even a small-scale nuclear conflict at the Ukraine–Russia border could cause years of severe global climate disruption and radioactive fallout across much of the world, new research suggests.

These eight coastal cities sit on America's flood front line, and AI shows why‎

New York, New Orleans and Miami are among the eight cities along the US Gulf and Atlantic coasts facing the highest flood risk, according to a new study published in Science Advances. Scientists developed a new AI-driven framework and combined it with historical flood-damage data to not only identify high-risk coastal areas but also pinpoint the underlying factors driving that risk.

Research shows community help essential for native bats‎

Community help is no longer just nice to have in the world of bat conservation, it is essential to large-scale bat monitoring and the protection of threatened and understudied species, according to new research from Murdoch University's School of Environmental and Conservation Sciences. The study reveals that collaboration between universities, not-for-profits, government agencies and community members is the key to ensuring data collection is accurate, and that it flows into policy and practice.

Gene-sharing view challenged as bacteria shown to police DNA exchange‎

A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view that bacteria freely exchange genetic material and reveals a more competitive system in which microbes tightly control who gets access to valuable traits, an insight that could help scientists better understand and potentially limit the spread of antibiotic resistance.

New study highlights private–public partnership advancing coastal resilience in Woods Hole‎

A new paper published in Frontiers in Marine Science presents lessons learned from and practical strategies for how small coastal communities can respond to increasing risks from sea-level rise and coastal flooding through coordinated actions, as outlined by the ResilientWoodsHole (RWH) initiative.

More realistic content may reduce social media harms for new moms‎

Scrolling through picture-perfect portrayals of motherhood may be doing real harm to moms, but a new study from University of Nebraska–Lincoln media scholar Ciera Kirkpatrick shows a "dose of reality" may mitigate some of the damage.

Neanderthals may have shared key DNA for complex language, reshaping when human speech began‎

In a first-of-its-kind finding, researchers at University of Iowa Health Care discovered that specific genetic sequences have an outsized impact on humans' language abilities and that these sequences evolved before humans and Neanderthals diverged.

How an Atlantic island narrowly escaped 'stealthy' eruption‎

Thousands of earthquakes affecting Portugal's São Jorge Island in the Azores in March 2022 were triggered by a vast sheet of magma (molten rock) rising from more than 20km below Earth's surface and stalling just 1.6km beneath the island, according to a new study led by UCL (University College London) researchers.
