Under-ice species at risk as Arctic warms

Under-ice species in the Arctic are facing significant threats as sea ice melts at a faster rate than anywhere else on Earth. Researchers studying microbial organisms in four environments found that the under-ice mix of species was the least diverse, composed mainly of specialist plankton and microbes adapted to harsh conditions.

Delay and pay: Tipping point costs quadruple after waiting

A new study finds that reversing climate change effects quickly climbs nearly fourfold soon after a tipping point is crossed. The cost of intervention also increases steeply if waiting occurs, with the degree of needed action rising over time. Researchers have quantified these costs for the first time.

It might be wrecking the climate, but CO₂ is actually good for your cells

A team of University of Utah chemists discovered that bicarbonate in CO₂ helps balance pH levels and alters the Fenton reaction, producing milder radicals. This finding challenges how cell damage has been studied for decades and may reshape our understanding of oxidative stress in diseases like cancer or aging.

Two-way water transfers can ensure reliability, save money for urban and agricultural users during drought in Western U.S., new study shows

A new study proposes a solution to water scarcity during droughts by coordinating agricultural-to-urban leasing during dry periods and urban-to-agricultural leasing during wet periods. This arrangement benefits both urban and agricultural water users, reducing financial impacts.

Bringing genomics into public policy requires greater awareness, professional training, and investment

The WHO's Technical Advisory Group on Genomics published an article outlining challenges and actions to promote the use of genomics in public health. The group aims to increase awareness and provide technical guidance to accelerate access to genetic technologies, enabling preventive measures and targeted treatment for various diseases.

Inside the ‘swat team’ – how insects react to virtual reality gaming

Researchers from Flinders University and international partners developed a VR platform to observe insect behavior, including hoverflies and crabs. The study provides insights into how these tiny creatures interact with virtual reality environments, paving the way for future research on animal behavior and decision-making.
