Phys.org / Astronomers thought the early universe was full of hydrogen: Now they've found it
The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called "Lyman-alpha nebulae," surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic ...
Phys.org / 'Hot Jupiter' orbiting a metal-poor star discovered
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new "hot Jupiter" exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which ...
Phys.org / Alignment during conversations is highly situation-dependent, study finds
When people are talking, they can start to unconsciously mirror each other, for instance, in the words they use, their sentence structures and even hand gestures. This tendency to mirror others can lead to smoother conversations, ...
Phys.org / Bacteria are weaving forever chemicals directly into their cell membranes, study finds
University of Tennessee Knoxville professor and Goodrich Chair of Excellence in Civil Engineering Frank Loeffler and his co-authors published new research on the environmental impacts of "forever chemicals" in Nature Microbiology. ...
Phys.org / How to eat an elephant: Fossil find in Tanzania shows oldest signs of butchering these giant mammals
Imagine a creature nearly twice the size of a modern African elephant, which can weigh up to 6,000 kg. This was Elephas (Paleoxodon) recki, a prehistoric titan that roamed the landscape of what is now Tanzania nearly two ...
Phys.org / Global warming may be a boon for this aggressive prairie plant
Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge. That's one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields ...
Phys.org / A nanoparticle therapy to treat lung cancer and associated muscle wasting at the same time
Researchers at Oregon State University have developed a technique for simultaneously treating lung cancer and a serious muscle-wasting condition that often accompanies it. The study, published in the Journal of Controlled ...
Phys.org / Fluorescence imaging technique reveals hidden magnetic chemistry in living systems
A research team at the University of Tokyo has developed a new microscopy platform that can observe a previously hidden layer of biomolecular chemistry linked to weak magnetic fields. The work, led by Project Researcher Noboru ...
Phys.org / Pigeons tend to respond 'at the edge of chaos,' study finds
If you were rewarded for following a particular pattern of behavior, wouldn't you keep doing it? The answer turns out to be more nuanced than you might think. In a new study, University of Iowa researchers report that pigeons ...
Phys.org / Study finds 70% of remediated Los Angeles yards still exceed lead limit
Even after one of the largest environmental remediation efforts in California history, dangerous levels of lead persist in residential neighborhoods surrounding a former battery smelter in Southeast Los Angeles, according ...
Phys.org / Origins of Earth's most powerful ocean current revealed
It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current rushes around the southern continent unhindered by land masses and is therefore a fundamental component ...
Phys.org / Water-repelling surfaces reveal surprising charging effects
Materials that repel water are used in countless applications, including industrial separation processes, routine laboratory pipetting, and medical devices. When water touches these surfaces, the interface where they meet ...
