Biologists from The University of Texas at Arlington are the first to discover an invasive frog—the greenhouse frog—in the Marshall Islands, a sprawling Pacific nation of volcanic islands and coral atolls located roughly halfway between Hawaii and Australia.

1.6 billion animals are transported in the EU each year. From day-old chickens to pregnant cows, they vary in size, sensitivities and needs.

The current legislation on animal welfare during transport is almost 20 years old and no longer responds to modern realities or the latest scientific knowledge. The experts worry that the same can be said about aspects of the proposal currently on the table.  

The proposal was presented in 2023 and aims to “Ensure a higher level of animal welfare by bringing animal welfare requirements closer to the latest scientific evidence” and to “reduce animal welfare problems linked to long journeys and repetitive loading and reloading linked to several rest periods.”

As the legislation is currently being discussed, three leading experts in the field now join the debate, noting that there are potential problems with both of these statements.

In a virtually unprecedented alignment of efforts, Europe’s major fusion research experiments have simultaneously entered a high-intensity experiment phase, showcasing Europe's strong collaboration and leadership in the global quest to develop fusion as a sustainable energy source.

As measles cases rise across Texas and the nation, a team of researchers at Rice University and the Houston Health Department is leveraging wastewater surveillance to detect the virus in the community. This innovative approach is part of the Houston Wastewater Epidemiology system and offers public health officials a powerful early warning system to track outbreaks and mobilize targeted interventions.

Eleven governors and their state energy offices are putting out ready-for-business signs to advanced nuclear energy developers under an initiative that taps into experts at the Idaho National Laboratory (INL).

Plastics are becoming more present in the seas and oceans around the world. The Mediterranean — a semi-enclosed marine basin — is one of the seas that accumulates more plastic waste from the continent, a situation that is endangering biodiversity and marine ecosystems. Now, the University of Barcelona is working on a citizen science project to better understand the origins and final destination of the plastics that reach the sea and thus improve the marine environment conservation strategies in the north-western Mediterranean.

The winter growth period for sea ice in the Arctic Ocean is now over, with levels at a record low. The winter ice extent on 21 March 2025 was lower than at any time since continuous satellite recording began in 1979. At 14.45 million square kilometres, winter sea ice cover is over a million square kilometres below the long-term average. As in February 2025, average Arctic sea ice cover remained at an all-time low for the entire month of March, equalling the previous low set in 2017.

From designing and manufacturing hundreds of ventilators to support critically ill patients in Peru during the height of the COVID-19 pandemic to bringing prenatal and breast-cancer imaging to women in rural areas of Peru, Professor Benjamín Castañeda's career is focused on providing medical technology to people who would otherwise not have access.

Jennifer Morgan, senior scientist at the Marine Biological Laboratory, Woods Hole, studies how the synapse malfunctions in devastating diseases such as Parkinson’s and Lewy body dementia. Now, her lab has spawned a large collaboratioin to understand how condensates -- liquid-like droplets that spontaneously form inside cells -- play a role in synaptic health and disease, in collaboration with Drago Milovanovic of the German Center for Neurodegenerative Diseases (DZME).
