No "human era" in Earth"s geological history, scientists say
A top panel of geologists has decided not to grant the 'human age' its own distinct place in Earth's geological timeline after disagreeing over when exactly our era might have begun......»»
Pyramids built along long-lost river, scientists discover
Scientists have discovered a long-buried branch of the Nile river that once flowed alongside more than 30 pyramids in Egypt, potentially solving the mystery of how ancient Egyptians transported the massive stone blocks to build the famous monuments......»»
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.....»»
Tracing the history of perturbative expansion in quantum field theory
Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theo.....»»
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.....»»
Stiffness and viscosity of cells found to differ in cancer and other diseases
During illness, the stiffness or viscosity of cells can change. Tom Evers demonstrated this by measuring such properties of human immune cells for the first time. "The stiffness of certain cells could be a way to make a diagnosis," Evers said......»»
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.....»»
