A new mechanism for shaping animal tissues
A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, Germany, the Exce.....»»
Death and grief in Swedish children"s books
Death is blue, or a flying animal. This is how death is most commonly illustrated in Swedish children's literature, according to a new study from Uppsala University based on analyses of 62 books. Just 6 out of 10 books use the word "dead," which may.....»»
New aging mechanism discovered in nematodes
Even the genes and proteins that have been most closely studied are still far from having given up all their secrets. Like a Swiss Army knife, they have many different, often unknown functions......»»
Cracking the code to a healthier potato chip
In a breakthrough for the snack food industry, a team of scientists led by Michigan State University professors Jiming Jiang and David Douches has discovered a key mechanism behind the darkening and potential health concerns associated with cold-stor.....»»
Using metabolomics for assessing safety of chemicals may reduce the use of lab rats
Scientists have discovered a more robust way of grouping chemicals and using read-across for toxicological data to meet regulatory requirements, which could greatly reduce animal testing......»»
Unlocking the energetic secrets of collective animal movement: How group behavior reduces energy costs in fish
Many animals, including apex predators, move in groups. We know this collective behavior is fundamental to the animal's ability to move in complex environments, but less is known about what drives the behavior because many factors underlie its evolut.....»»
How decentralized identity is shaping the future of data protection
In this Help Net Security interview, Patrick Harding, Chief Architect at Ping Identity, discusses the promises and implications of decentralized identity (DCI) in cybersecurity. By redistributing identity management responsibilities among issuers, ho.....»»

Scientists create method to bond hydrogels and other polymeric materials using chitosan
Hydrogels are versatile biomaterials conquering an increasing number of biomedical areas. Consisting of water-swollen molecular networks that can be tailored to mimic the mechanical and chemical features of various organs and tissues, they can interf.....»»
Men become less fertile with age, but the same isn"t true for all animals: Study
We take it for granted that humans find it more difficult to conceive as they grow older. But our recent study, which analyzed data from 157 animal species, found that male reproductive aging seems to be a lot less common in other male animals......»»
Newly discovered bacterial defense system functions as self-destruct button
Wageningen researchers have discovered a molecular self-destruct mechanism in a bacterium living on seaweed. With this mechanism the bacteria sacrifice themselves when they are infected, thus protecting their brothers and sisters from infections. By.....»»
Scientists identify genetic mechanism responsible for plant leaf diversity
Plant leaves come in many different shapes, sizes and complexities. Some leaves are large and smooth, while others are smaller and serrated. Some leaves grow in single pieces while others form multiple leaflets. These variations in leaf structure pla.....»»
Researchers identify human activities as drivers of biodiversity decline in central Mexico"s reserves
New research shows the diversity of plant and animal life in 14 tropical reserves in Mesoamerica has plummeted since 1990 as roads and cattle ranches have expanded into protected areas. Large mammals, birds, and reptiles are disappearing, while disea.....»»
How a wayside weed builds up explosive force to hurl seeds
Hairy bittercress is one of those plants that hurl their seeds in all directions to spread them effectively. A research team has now discovered that to do this, the plant uses a previously unknown mechanism that makes the seed pods contract and snap.....»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
When an enemy invades, defenders are ferried to the site to neutralize the marauders. In the human body, a protein carrier called SPNS2 transports S1P molecules from endothelial cells to rally immune cell response in infected organs and tissues......»»
Linux Leaps Ahead: Dynamic Future of Linux in 2024
As we journey through 2024, the world of Linux is witnessing a fascinating evolution, shaping the technology landscape with innovative trends and promising developments. We cannot overlook the increasing relevance of Virtual Private Networks in the L.....»»
New study finds little-known toxic crop chemical in four out of five people tested
A new Environmental Working Group study has found chlormequat, a little-known pesticide, in four out of five people tested. Because the chemical is linked to reproductive and developmental problems in animal studies, the findings suggest the potentia.....»»
Some pre-Roman humans were buried with dogs, horses and other animals
Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between t.....»»
New logging rules in New South Wales put the greater glider closer to extinction
Forty years ago when my colleagues and I did spotlighting surveys, the southern greater glider was the most common animal we'd see. Now, this amazing species is endangered. In many areas it is hard to find; in others it has been lost altogether......»»
By growing animal cells in rice grains, scientists dish up hybrid food
From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, Korean scientists add a new recipe to the list—cultured b.....»»
Discovery of a subset of human short introns that are spliced out by a novel mechanism
The well-known essential pre-mRNA splicing factor U2AF heterodimer (U2AF2–U2AF1) has been identified as mediating early splicing reactions in all introns of different lengths. However, Dr. Kazuhiro Fukumura in the Akila Mayeda lab at Fujita Health.....»»
