Trump Meeting With NATO Secretary General at White House

Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent catalyst deactivation in a key hydrogen production reaction, maintaining stable performance for 30 hours while also changing how the reaction proceeds at the molecular level.

In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously confirms the detection of organic carbon, the building blocks of life, in the same two rocks from the Bright Angel formation, and describes in more detail exactly what we can say about that organic matter.

Deep within the dark caves of northeastern Mexico lives a fish that has spent hundreds of thousands of years adapting to a world without light. The blind Mexican cavefish (Astyanax mexicanus) has evolved in perpetual darkness, losing its eyes and pigmentation while developing remarkable adaptations that help it survive in nutrient-poor environments.

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser technology. The team's results have been published in Optica.

Medical advancements over the last several decades have made great strides in the treatment of HIV. Pharmaceutical treatments are able to contain and reduce a patient's viral load to the point where it is nearly undetectable. But a cure remains frustratingly elusive due to the virus's ability to evade the immune system. Researchers from Drexel University and the University of Pennsylvania, who specialize in modulating immune responses, have offered a new approach—one that's likely familiar to anyone who has dealt with pest removal: setting a trap.

When an animal's environment changes faster than the animal can adapt, its chances of survival can flatline. The same is true for populations and even entire species. Now, scientists at MIT and the University of Leicester have found that this connection between evolutionary adaptation and the pace of environmental change holds up at the global scale as well—and can determine life's susceptibility to mass extinction. The researchers have developed a theoretical model of this phenomenon, which they present in a paper published today in Physical Review Letters.

When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an international team of researchers has directly observed at the European XFEL how the protein shells of viruses can change shape during dehydration, offering new clues to viral resilience and opening new possibilities for virology research. The results, published in Light: Science & Applications, lay the groundwork for potential applications in virology and public health and can, for instance, help develop antiviral strategies.

A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA's Nancy Grace Roman Space Telescope, launching later this summer. This sneak peek gives astronomers a major jumpstart on a core Roman survey, helping scientists learn more than they could from either telescope alone.

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, but then unexpectedly returns when the magnetic field is increased further.
