Study discovers how algae produce a hormone they use to communicate
A study at the University of Cordoba shows how algae produce auxin, a plant hormone, opening a path of communication with bacteria to generate synergies that could benefit agricultural production. The paper is published in the journal iScience......»»
First successful test of wild minke whales reveals they have ultrasonic hearing
A team of marine biologists from Norway, the U.S. and Denmark has conducted the first hearing test of a live baleen whale. For their study published in the journal Science, the group corralled a pair of wild minke whales and recorded their brain wave.....»»

Caste differentiation in ants: How a specific hormone regulates the process
Scientists from the University of Copenhagen have revealed how a specific hormone regulates ant caste differentiation by phenotypic measurements of organ-level developmental changes and matching transcriptome analyses. Published in the Proceedings of.....»»
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......»»
Natural substance from edible cyanobacterium could combat skin aging by enhancing collagen
Cyanobacteria, or blue-green algae, have existed for billions of years, adapting to a diverse range of environments. Their remarkable ability to photosynthesize and make their own food, as well as their adaptability across a variety of habitats, make.....»»
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.....»»
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......»»
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.....»»
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......»»
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
Police radio transmissions contain personally identifiable information that could pose privacy risks for members of the public, especially Black males, according to a new study by researchers at Penn State and the University of Chicago......»»
Study: Yes, tapping on frescoes can reveal defects
Acousticians put a traditional "knock" test for delaminated areas to the test. The US Capitol building in Washington, DC, is adorned with multiple lavish murals created in the 19t.....»»
Introducing "UFO" galaxies—the Milky Way"s dustier cousins
In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red Flattened Objects, or UFOs.....»»
Oldies but goodies: Study shows why elderly animals offer crucial scientific insights
A new study on aging in the animal kingdom has highlighted how urgently Earth's oldest and wisest creatures must be protected, with knowledge and environmental stability lost due to human intervention......»»
Florida panthers deemed unaffected by emerging fatal genetic condition in new research
University of Central Florida researchers have helmed a study that found Florida panthers are not particularly susceptible to a potentially transmissible disease that causes cognitive decline leading to death in their prey. The findings abate concern.....»»
Cash grants are better than earmarked matching grants for businesses in Burkina Faso
Cash grants appear to be more promising than matching grants, especially if the survival of small businesses, rather than innovation, is the key objective in fragile political contexts. This is the result of a study conducted by economists from the U.....»»
Gene expression shifts help explain how a shrew changes brain size to match the seasons
New research shows how the Eurasian common shrew (Sorex araneus) changes its brain and bodily size throughout the year. The study, published online in eLife, reveals how changes in gene expression enable these small mammals to shrink their brain in.....»»
