In a set of policy recommendations produced by the University of Jyväskylä, researchers examine the development of sustainable livelihoods in the Sundarbans, a coastal region of India and Bangladesh that is vulnerable to the impacts of climate change. The Sundarbans is one of the largest threatened mangrove ecosystems, which efficiently store carbon dioxide and protect coastal areas from cyclones. In a research project funded by the Research Council ...

Shark sightings by scuba divers reveal the movements of marine predators throughout the year, according to a study published February 26, 2025 in the open-access journal PLOS One by George Balchin, William Hughes and colleagues at the University of Sussex, U.K., and Aquaplanet Dive Center, South Africa. Many sharks move through different habitats as they follow food or search for mates. Since they are major predators, they change the shape of the ecosystems they visit. Examining these movements is key to understanding the health of ocean habitats as well as the impacts of human activity, but it is notoriously ...

KINGSTON, R.I. – Feb. 26, 2025 – Animal antics have captured public attention and viral views across the U.S. in the last few years with the advent of mini cameras that capture the movements of animals in front yards nationwide, from bear to deer. A University of Rhode Island-based group has taken the camera concept one step further and then some, generating a massive dataset of animal images, not for entertainment, but for science.  When the Global Animal Diel Activity Project results were analyzed, researchers made some unique discoveries.  Put together, researchers across the country and around the world generated a more focused picture of animal ...

From mountain goats that run up near-vertical rock faces to armadillos that roll into a protective ball, animals have evolved to adapt effortlessly to changes in their environment. In contrast, when an autonomous robot is programmed to reach a goal, each variation in its pre-determined path presents a significant physical and computational challenge. Researchers led by Josie Hughes in the CREATE Lab in EPFL’s School of Engineering wanted to develop a robot that could traverse diverse environments as adeptly as animals by changing form on the fly. With GOAT (Good Over All Terrains) they have achieved just that – and created a new paradigm for robotic ...

A groundbreaking study published in Science Advances sheds new light on the mysterious origins of free-floating planetary-mass objects (PMOs)—celestial bodies with masses between stars and planets. Led by Dr. DENG Hongping of the Shanghai Astronomical Observatory of the Chinese Academy of Sciences, an international team of astronomers used advanced simulations to uncover a novel formation process for these enigmatic objects. The research suggests that PMOs can form directly through violent interactions between circumstellar disks in young star clusters. The Mystery of Rogue Planetary-Mass ...

ANN ARBOR—Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to release, the plates slip and grind against each other, causing an earthquake.  Researchers have long thought that this force is the central driver of earthquakes. But another force is also in the mix: the properties of the rocks in the fault zones along the plate interface. This includes both the structure of the rock as well as how the rocks are arranged along the zones.  Now, a University of Michigan study looking at a small ...

During and after the height of the COVID-19 pandemic, telehealth appointments became a more common part of the American health care system. But even as telehealth options grow, barriers such as long waitlists or a lack of a stable internet connection mean many communities still do not have access to care, particularly for mental health services. The University of Cincinnati, the Adams County Health Department (ACHD) and other local partners are testing a new collaborative care model that aims to remove these barriers and provide more students access to telemental health care. The team recently received a $1.75 million grant from the Health ...

The practice of purposely looping thread to create intricate knit garments and blankets has existed for millennia. Though its precise origins have been lost to history, artifacts like a pair of wool socks from ancient Egypt suggest it dates back as early as the 3rd to 5th century CE. Yet, for all its long-standing ubiquity, the physics behind knitting remains surprisingly elusive. “Knitting is one of those weird, seemingly simple but deceptively complex things we take for granted,” says ...

OKLAHOMA CITY – A new study published in Communications Medicine, a Nature publication, details the discovery of rare gene variants that increase the prevalence of Type 2 diabetes in multiple generations of Asian Indian people. The unusual finding is a step toward more targeted treatment for all people with Type 2 diabetes, a disease with complex genetic influences. “We wanted to study several generations of Asian Indians because understanding genetics in families can give us better information, and Asian Indians have up to six times higher risk of developing Type 2 diabetes than Europeans. In addition, Asian Indians tend to live clustered together and marry ...

The perfusion technique developed at UMCG to test the quality of donor livers led to a record number of liver transplants last year. Not only in Groningen, but throughout the Netherlands. Meanwhile, there is worldwide interest in this perfusion technique. Donor livers can only be stored outside the body for a short time, up to 6 to 10 hours. The organ must therefore get to the recipient as quickly as possible. As a result, transplants have always been under great time pressure. The UMCG has had an ‘Organ Preservation & ...

Endophytes: A plant’s friends or foes Endophytes are microorganisms that live inside plants. Some of these organisms, mostly bacteria or fungi, make the plants sick, while others have no harmful effect on the plants or are even beneficial. Previous studies of endophytic fungi living inside certain grasses have shown that these fungi provide the grasses with a defense against predators. However, little has been known about whether this is also true for trees. The current study investigated the influence of an endophytic fungus of the genus Cladosporium on the herbivore defense of the black poplar Populus nigra, as well as the effects on the insect communities that live on poplars. "We ...
