Once they have laid their eggs, fish become "young" again: Study
The physical relief—in body weight—that temperate fish like cod and Atlantic herring experience after they spawn for the first time allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in.....»»
New maps show high-risk zones for whale-ship collisions—vessel speed limits and rerouting can reduce the toll
Imagine you are a blue whale swimming up the California coast, as you do every spring. You are searching for krill in the Santa Barbara Channel, a zone that teems with fish, kelp forests, seagrass beds and other undersea life, but also vibrates with.....»»
Extending classical black hole inequalities into the quantum realm
A recent study in Physical Review Letters explores quantum effects on black hole thermodynamics and geometry, focusing on extending two classical inequalities into the quantum regime......»»
Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they.....»»
In Patagonia, more snow could protect glaciers from melt—but only if greenhouse gas are curbed emissions soon
In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study in Scientific Reports from INSTAAR postdoc Matthias Troch suggests that this protective effect might be pushed up against i.....»»
Peaches spread across North America through Indigenous networks, radiocarbon dating and document analysis show
Spanish explorers may have brought the first peach pits to North America, but Indigenous communities helped the ubiquitous summer fruit really take root, according to a study led by a researcher at Penn State......»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Ancient fish-trapping network supported the rise of Maya civilization
The Maya were landscape engineers on a grand scale, even when it came to fishing. On the eve of the rise of the Maya civilization, people living in what’s now Belize turned a wh.....»»
Niagara fireball event leads to discovery of tiniest known asteroid
In an international study led by Western University and Lowell Observatory, scientists describe a pioneering, integrative approach for studying near-Earth asteroids based largely on a November 2022 fireball event that dropped meteorites in the Niagar.....»»
Next-generation, nature-inspired sunscreens have a new molecular scaffold
A team of researchers led by professors Wybren Jan Buma at the University of Amsterdam and Vasilios Stavros at the University of Warwick (U.K.) have laid the groundwork for using urocanic acid and its derivatives as a novel class of sunscreen filters.....»»
Study: Brilliant white male characters more believable, some viewers say
Brilliant characters often play key roles in movies and TV shows. However, when these characters are played by women and people of color, some audience members dismiss them as unrealistic, even if they portray real people and events, a recent study f.....»»
Image-processing method enhances visualization of electron microscope images in rubber materials
Researchers at University of Tsukuba have developed a new imaging method that clearly visualizes nanoscale structures within rubber materials. The study is published in the journal ACS Applied Nano Materials......»»
Educating young people about social media could be far more effective than a ban—Finland can show us how
The federal government's proposed social media ban for under-16s has sparked widespread debate, affecting millions of young Australians, their families and educators. But will it actually work?.....»»
Parasaurolophus pipes: Modeling the dinosaur"s crest to study its sound
Fossils might give a good image of what dinosaurs looked like, but they can also teach scientists what they sounded like. The Parasaurolophus is a duck-billed dinosaur with a unique crest that lived 70 million to 80 million years ago. It stood around.....»»
"Doomsday fish" washed ashore in California, but what does that mean?
If one oarfish landing on a beach is a sign of a disaster to come, how bad will it be if three wash up in quick succession?.....»»
Low levels of common contaminants but high levels of other elements in waters linked to abandoned lithium mine
Lithium ore and mining waste from a historic lithium mine located west of Charlotte, North Carolina, are unlikely to contaminate surrounding waters with common pollutants such as arsenic and lead, according to a new study......»»
Hubble finds sizzling details about young star FU Orionis
In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our sun. Unlike an exploding.....»»
Study reveals RNA"s unknown role in DNA damage repair
A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative disorders while chan.....»»
Broadcast police communications may pose privacy risks, especially to Black men
