The 10,000-mile march through fire that made dinosaurs possible

https://www.sciencedaily.com/releases/2025/06/250613013903.htm

Despite Earth's most devastating mass extinction wiping out over 80% of marine life and half of land species, a group of early reptiles called archosauromorphs not only survived but thrived, venturing across the supposedly lifeless tropics to eventually evolve into the dinosaurs and crocodiles we know today. Armed with a groundbreaking model dubbed TARDIS, researchers have reconstructed their ancient dispersal routes, revealing how these resilient reptiles conquered a hostile, post-apocalyptic Earth.

New MIT study reveals how biofilms help stop microplastic build-up

https://www.sciencedaily.com/releases/2025/06/250613013823.htm

Where do microplastics really go after entering the environment? MIT researchers discovered that sticky biofilms naturally produced by bacteria play a surprising role in preventing microplastics from accumulating in riverbeds. Instead of trapping the particles, these biofilms actually keep them loose and exposed, making them easier for flowing water to carry away. This insight could help target cleanup efforts more effectively and identify hidden pollution hotspots.

Guest molecules ride perfect waves in dna droplets—A breakthrough for synthetic biology

https://www.sciencedaily.com/releases/2025/06/250613013808.htm

Scientists have uncovered a previously unknown type of molecular motion inside DNA-based droplets: instead of spreading randomly, guest molecules advance in an organized wave. This surprising discovery opens the door to understanding how cells might organize internal processes without membranes. Using customizable DNA condensates as experimental models, the team showed how molecular waves emerge through precise DNA interactions. These insights could not only transform our grasp of cellular signaling but may even lay groundwork for treating neurodegenerative diseases by influencing how molecules behave inside aging cells.

Beyond Ozempic: New weight loss drug rivals surgery

https://www.sciencedaily.com/releases/2025/06/250612081323.htm

Tufts University scientists are aiming to revolutionize the future of weight loss drugs by engineering a new compound that targets four gut hormones instead of the usual one to three. These next-gen tetra-functional peptides may overcome the limitations of current drugs like Ozempic and Mounjaro especially their nausea, muscle loss, and rebound weight gain.

Brain-computer interface restores real-time speech in als patient

https://www.sciencedaily.com/releases/2025/06/250612081317.htm

A team at UC Davis has made a major leap in neurotechnology, enabling a man with ALS to speak again through a brain-computer interface that converts thoughts into speech in real time. Unlike prior systems that translated neural signals into text, this one synthesizes actual voice with tone, pacing, and even melody, creating a near-conversational experience. The device interprets neural signals via implants and advanced AI, making it possible for users to speak new words, ask questions, and express emotions vocally. Though still early-stage, this breakthrough offers real hope for those silenced by neurological conditions.

Viruses closely related to the deadly MERS coronavirus are lurking in bats and one group, known as HKU5, may be just one mutation away from making the jump to humans. A new study reveals how these viruses bind to cell receptors and even shows signs of adapting to human-compatible versions of those receptors.

The hunger switch in your nose: How smells tell your brain to stop eating

https://www.sciencedaily.com/releases/2025/06/250612031553.htm

A team of scientists has discovered a direct link between the smell of food and feelings of fullness at least in lean mice. This brain circuit, located in the medial septum and triggered by food odors, helps animals eat less by making them feel satiated even before taking a bite. But intriguingly, obese mice lacked this response, highlighting how excess weight may interfere with this satiety mechanism. The finding could have major implications for how we think about the role of smell in appetite and offer new strategies to combat overeating.

Rivers are exhaling ancient carbon — and climate math just changed

https://www.sciencedaily.com/releases/2025/06/250612092543.htm

Ancient carbon thought to be safely stored underground for millennia is unexpectedly resurfacing literally. A sweeping international study has found that over half of the carbon gases released by rivers come from long-term, old carbon sources like deep soils and weathered rocks, not just recent organic matter. This surprising discovery suggests Earth s vegetation is playing an even bigger role in absorbing excess carbon to keep the climate in check.

Atom-thin tech replaces silicon in the world’s first 2D computer

https://www.sciencedaily.com/releases/2025/06/250612031705.htm

In a bold challenge to silicon s long-held dominance in electronics, Penn State researchers have built the world s first working CMOS computer entirely from atom-thin 2D materials. Using molybdenum disulfide and tungsten diselenide, they fabricated over 2,000 transistors capable of executing logic operations on a computer free of traditional silicon. While still in early stages, this breakthrough hints at an exciting future of slimmer, faster, and dramatically more energy-efficient electronics powered by materials just one atom thick.

Mercury contamination is surfacing as a serious concern in parts of Georgia and South Carolina, particularly in regions like the Okefenokee Swamp. University of Georgia researchers found alarmingly high levels of the neurotoxic metal in alligators, especially in older individuals and even hatchlings suggesting the toxin is passed both up the food chain and through generations. These ancient reptiles act as environmental indicators, raising red flags for the broader ecosystem and potentially for humans who fish or hunt nearby.

NASA s CODEX experiment aboard the International Space Station is revealing the Sun like never before. Using advanced filters and a specialized coronagraph, CODEX has captured images showing that the solar wind streams of charged particles from the Sun is not a smooth, uniform flow but rather a turbulent, gusty outpouring of hot plasma. These groundbreaking observations will allow scientists to measure the speed and temperature of the solar wind with unprecedented detail, providing critical insights for space weather forecasting and understanding how solar activity impacts Earth and space technology.

Pincer plot twist: How female earwigs evolved deadly claws for love and war

https://www.sciencedaily.com/releases/2025/06/250612001244.htm

Female earwigs may be evolving exaggerated weaponry just like males. A study from Toho University found that female forceps, once assumed to be passive tools, show the same kind of outsized growth linked to sexual selection as the male's iconic pincers. This means that female earwigs might be fighting for mates too specifically for access to non-aggressive males challenging long-standing assumptions in evolutionary biology.

Astronomers just found a giant planet that shouldn’t exist

https://www.sciencedaily.com/releases/2025/06/250611085304.htm

Scientists have discovered a giant planet orbiting a tiny red dwarf star, something they believed wasn t even possible. The planet, TOI-6894b, is about the size of Saturn but orbits a star just a fifth the mass of our Sun. This challenges long-standing ideas about how big planets form, especially around small stars. Current theories can't fully explain how such a planet could have taken shape. Even more fascinating, this cold planet may have a rare kind of atmosphere rich in methane or even ammonia something we've never seen in an exoplanet before.
