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 / A new equation may help baristas produce the perfect espresso shot every time
Everyone's idea of the perfect cup of coffee is different. Whether you have yours black, with a splash of milk or extra sweet, you like it your way. But is there a universal law that governs how that flavor gets into your ...
Phys.org / How the female baboon body has the final say in sperm selection
Just because a female olive baboon has mated with a specific male doesn't mean he will be the father of her offspring. According to a new study published in PLOS Biology, mate selection continues long after copulation as ...
Phys.org / Polymers built inside the body through blood-catalyzed chemistry allow on-demand brain control
The 19th-century science fiction novel Frankenstein explores the idea of combining artificial materials with human body components, purely as a matter of imagination. Two centuries later, such concepts have become integral ...
Phys.org / Scientists identify potential new target for disrupting mosquito reproduction
A longstanding mystery in mosquito biology has been solved, opening a potential new path for controlling mosquitoes and the diseases they spread. For decades, scientists believed that juvenile hormone, a chemical signal essential ...
Phys.org / Expanded MAGIC toolkit makes genome-wide single-cell mosaic analysis possible in Drosophila
Researchers at Cornell University have developed a powerful new genetic toolkit that allows scientists to study how genes function at the level of individual cells, an advance that could accelerate discoveries in development, ...
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 / Robotic floats uncover hidden ocean chemistry in low-oxygen zones
Scientists have found a new way to detect subtle chemical signatures in seawater, revealing previously invisible details about the ocean's chemistry from data continuously collected by thousands of autonomous robotic floats ...
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 / 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 / New York Bight is a key spring habitat for endangered sei whales, research reveals
A new study led by scientists from the Wildlife Conservation Society (WCS) and Woods Hole Oceanographic Institution (WHOI) reveals that endangered sei whales regularly use the New York Bight as a key spring habitat, underscoring ...
