United Launch Alliance was hoping to ramp up its new Vulcan rocket launches this year, but won't be launching any national security missions until it solves a recurring issue of booster nozzles burning off the rocket on launch.
Texas is known nationwide for its grueling hot summers. However, hurricanes and occasional winter weather can have a harsher impact on citizens and infrastructure due to the effects of power outages. Led by director and primary investigator Dr. Samuel Brody, researchers from
An international team combining two major neutrino experiments has uncovered stronger evidence that neutrinos and antimatter don’t behave as perfect mirror images. That subtle difference may hold the key to why the universe didn’t vanish in a flash of self-destruction after the
For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes by centuries. A new international study published in
Native forest restoration usually starts with faster growing "nurse plants" that provide shelter under which to plant bigger trees—but new research suggests some big canopy trees can be planted early too. Scientists monitored over 1800 canopy trees at restoration sites around
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. For the first time, researchers have observed this
In a dry riverbed in Brazil, in a dense forest near the Amazon, a team of paleontologists found a fossilized jawbone from an ancient animal. Over the course of their fieldwork, they found eight similar bones, each around six inches long—but no other bones that they could
Jackdaw chicks learn about predators by listening to adults, new research shows. Scientists played recordings of predator calls to chicks in their nests—and paired the sounds with either adult jackdaw "alarm" calls or "contact" calls that indicate no danger.

The wood-feeding cockroach’s cannibalistic love bites lead to a lasting bond. Afterward, the pair prefer each other over all other roaches.
Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their findings in Monthly Notices of the Royal Astronomical Society, researchers from the
In the ocean, a haze made from tiny bits of dead plants, animals, and microbes hangs in the upper reaches of the water. Each particle is just a fraction of a micrometer across, but together the carbon within these particles weighs about 700 billion tons—about as much as all the
For decades, scientists have relied on a chemical fingerprint inside water molecules to determine where plants get their moisture. The method shaped our understanding of drought resilience, groundwater use, and ecosystem survival. But there was a problem. The fingerprints
For decades, the basics of plant growth have been taught in grade school: Plants make their food out of water from the soil, light from the sun and carbon dioxide from the air in a process called photosynthesis. What gets less attention is that plants release some of that
In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this phenomenon have remained largely unknown. In a study
Pollen exposure is linked to poorer exam results taken at the end of secondary (high) school (matriculation), with the effects especially noticeable in subjects involving math, including physics and chemistry, finds research published online in the Journal of Epidemiology &
Crystalline nanomaterials are valuable because their highly ordered structures give them useful properties for technologies such as data storage and optical devices. But forming nanoparticles from those orderly crystals is difficult because, instead of snapping into place, the
Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can influence biological systems, be separated from one another and more. To fully
When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other remote place, and stumbling across a creature that no
Japanese snow monkeys don’t just soak in hot springs to escape the winter chill — their steamy spa sessions may also be reshaping their invisible world. Researchers in Japan found that macaques who regularly bathe show subtle but intriguing differences in lice patterns and gut
In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered nature allows stacking, twisting and interfacing with a remarkable atomic
For years, the Prairie Pothole Region has bothered me in a very specific way. On a map, it looks like a normal landscape: fields, gentle slopes, small streams. But hydrologically, it behaves like something else entirely. The surface is peppered with countless
A recent study published in PLOS ONE has shed light on public perceptions of assisted reproductive technologies (ART) in wildlife conservation across Czechia, Germany, and Italy. The research, conducted as part of the BioRescue project, highlights public attitudes toward ART,
