Scientists Fine-Tune Odds of Asteroid Bennu Hitting Earth
NASA's OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agency's existing models of its trajectory. "As a result, scientists behind new research now say they're confident that the asteroid's to.....»»
When the first warm-blooded dinosaurs roamed Earth
Scientists once thought of dinosaurs as sluggish, cold-blooded creatures. Then research suggested that some could control their body temperature, but when and how that shift came about remained a mystery......»»
Global coral bleaching event expanding to new countries: Scientists
The massive coral bleaching episode signaled by US authorities last month is expanding and deepening in reefs around the globe, scientists warned Thursday......»»
Using vague language about scientific facts misleads readers
Using subjective phrasing like "scientists believe" makes facts seem like opinions. Enlarge Anyone can do a simple experiment. Navigate to a search engine that offers suggested completions for what you type, and start t.....»»
Earth from space: New Zealand"s North Island
Captured on 7 May 2024, this Copernicus Sentinel-2 image shows part of New Zealand's North Island......»»
Study reveals how a sugar-sensing protein acts as a "machine" to switch plant growth—and oil production—on and off
Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living things—and potentially how to change its effects. Biochemists at the U.S. Dep.....»»
Scientists develop new geochemical "fingerprint" to trace contaminants in fertilizer
An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants on soil, water resources, and food supply......»»
How your aurora photographs are helping NASA study solar storms
The most dramatic solar storm in decades wasn't only notable for the gorgeous colors seen in the sky -- it's also a way for scientists to learn about the sun......»»
Airborne technology brings new hope to map shallow aquifers in Earth"s most arid deserts
Water shortages are expanding across the Earth. This is particularly acute in desert areas of the Middle East that are subject to both drought and extreme conditions such as flooding. As a result of these uncertainties, there is an increasing relianc.....»»
Enhancing land surface models to visualize vegetation gradients in hilly terrain
Land surface models are an indispensable tool for environmental scientists to map the natural features of our world, particularly when they monitor the effects of climate change or assess conservation efforts......»»
Scientists demonstrate the survival of quantum coherence in a chemical reaction involving ultracold molecules
If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationsh.....»»
Researchers achieve ultra-high-Q free space coupling to microtoroid resonators
Scientists from the University of Arizona have achieved far-field coupling of light to ultra-high quality factor microtoroids using a single objective lens. This could provide the foundation for a fully on-chip multiplexed microtoroid sensing platfor.....»»
Transformation and mechanisms of climate wet/dry change on the northern Tibetan Plateau under global warming
Historical patterns of climate change can provide ways to predict future climate change. During geological history, the earth has experienced many warm periods of different time scales, such as the mid-Holocene warm period, the medieval climate anoma.....»»
Scientists brew killer bee beer
Scientists from Cardiff University have used brewer's yeast that resides in the gut microbiome of killer honeybees in Namibia and applied it to develop a unique craft beer......»»
Experts say coral reef bleaching near record level globally because of "crazy" ocean heat
Ocean temperatures that have gone "crazy haywire" hot, especially in the Atlantic, are close to making the current global coral bleaching event the worst in history. It's so bad that scientists are hoping for a few hurricanes to cool things off......»»
AI can help researchers understand what viruses are up to in the oceans and in your gut
Viruses are a mysterious and poorly understood force in microbial ecosystems. Researchers know they can infect, kill and manipulate human and bacterial cells in nearly every environment, from the oceans to your gut. But scientists don't yet have a fu.....»»
Scientists use generative AI to answer complex questions in physics
When water freezes, it transitions from a liquid phase to a solid phase, resulting in a drastic change in properties like density and volume. Phase transitions in water are so common most of us probably don't even think about them, but phase transiti.....»»
Researchers uncover how jelly sea creatures might shape modern robotics
Scientists at the University of Oregon have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficie.....»»
How saber-toothed tigers acquired their long upper canine teeth
An international team led by scientists from the University of Liège has investigated the evolutionary patterns behind the development of saber teeth, with some unexpected results along the way. Their study has been published in the journal Current.....»»
NASA researchers bid farewell to "flying laboratory" at Ames Research Center
For many NASA scientists, flying aboard a decked-out Douglas DC-8 plane provided them some unique glimpses of Earth: the Moai on Easter Island, Central Park in New York and Mount Vesuvius in Italy......»»
A golden layer unlocks sharper imaging and faster scanning with X-rays
Scientists have made a breakthrough in significantly improving the sharpness of X-ray imaging and potentially boosting the speeds at which X-ray scans can be processed. This lays the groundwork for both better medical imaging and faster security clea.....»»
