NASA’s Roman Space Telescope will survey enormous regions of the sky with Hubble-like sensitivity, helping scientists study everything from dark energy to distant exoplanets. Credit: NASA NASA’s Roman Space Telescope will combine a panoramic view of the cosmos with powerful tools for probing dark energy and hidden worlds. NASA’s Nancy Grace Roman Space Telescope is just one day from launch, and it is built to see the universe in a way no major space telescope has before.

Seismic evidence suggests Mars may have developed vast, long-lived magmatic systems that repeatedly reshaped its crust despite lacking plate tectonics. Credit: Shutterstock Mars may have built a surprisingly complex crust through large magmatic systems without the plate tectonics long thought necessary. Mars has no moving tectonic plates, yet deep beneath its surface may lie evidence of the kind of vast, interconnected magmatic systems once thought to require them.

Researchers found that RNA droplets can shift from fluid structures into more rigid, gel-like networks. That behavior could have helped primitive molecules persist in the harsh environments of early Earth. Credit: Shutterstock A tiny chemical difference makes RNA better than DNA at forming liquid-like droplets under high temperatures and acidic conditions.

Some highly adapted gut bacteria may spread rapidly between people and even across continents. The finding suggests that microbial transmission could be an overlooked force shaping the human microbiome. Credit: Shutterstock In addition to diet and medication, person-to-person transmission can also play an important role in shaping the microbiome. The human gut contains a vast community of trillions of microorganisms (the microbiome) that helps shape digestion, immune function, and metabolism.

Prostate cancer is one of the most common cancers in men and often develops slowly, though some forms can become aggressive and spread to other parts of the body. Treatment depends on the stage and biology of the tumor, with advanced disease posing greater challenges as cancer cells evolve and become resistant to therapy. Credit: Stock Researchers identified a promising approach to slowing treatment-resistant prostate cancer by targeting two key cancer pathways at the same time.

A workout habit may not fully counter what happens inside the arteries during long periods of sitting. New findings suggest that regularly breaking up sedentary time could matter independently of improvements in fitness. Credit: Shutterstock Improved fitness did not prevent prolonged sitting from impairing blood-vessel function in the legs. Long hours of sitting are often treated as something a good workout can offset.

A newly cleared PTSD treatment uses patterns in brain activity to personalize magnetic stimulation. Researchers say the technique could mark a shift toward more objective, precision-guided mental health care. Credit: Stock The FDA has cleared a system that uses brain activity data to personalize magnetic stimulation for PTSD, adding a new nonmedication treatment option. A system developed by California-based Wave Neuroscience in collaboration with the research team of Dr. Kenneth S.

This AI image shows a chain of strontium atoms (orange), each held in an optical tweezer (blue cones). The chain sits within a modulated laser field. The evenly spaced lines above represent the ladder of excitation energies predicted by conformal field theory, whose rungs the team measured.

Montsecosuchus depereti seen under ultraviolet light, a technique that allows highlighting details invisible to the naked eye. Credit: Castillo-Visa, O. et al. Ultraviolet imaging of a 125-million-year-old crocodylomorph fossil has revealed unexpectedly detailed traces of skin, sensory structures, and chest cartilage. More than a century after a tiny Early Cretaceous crocodylomorph was unearthed in northeastern Spain, its fossil is revealing details that were hiding in plain sight.

Researchers have uncovered an unexpected way muscle cells may rebuild actin filaments while keeping their length tightly controlled. Credit: Shutterstock Researchers directly observed muscle actin filaments growing from an end long thought unable to support growth, revealing how the protein leiomodin 2 helps maintain their structure. Muscle cells face a peculiar problem.
