Residents, some of whom lack heat or basic amenities in their own homes due to the unusually chilly weather, have been rescuing cold-stunned sea turtles and taking them to a convention center in a South Texas resort town.

Residents and municipal teams worked Wednesday to clean up a Sicilian village near Mount Etna after Europe's most active volcano spewed lava, ashes and volcanic stones.

Dogs are generally considered the first domesticated animal, while its ancestor is generally considered to be the wolf, but where the Australian dingo fits into this framework is still debated, according to a retired Penn State anthropologist.

Deprive a mountain range of its wolves, and soon the burgeoning deer population will strip its slopes bare. "I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer," wrote ecologist Aldo Leopold in his landmark 1949 title "A Sand County Almanac."

A new UBC Okanagan study finds children not only reap the benefits of working with therapy dogs—they enjoy it too.

When materials reach extremely small size scales, strange things begin to happen. One of those phenomena is the formation of mesocrystals.

A considerable portion of the efforts to realize a sustainable world has gone into developing hydrogen fuel cells so that a hydrogen economy can be achieved. Fuel cells have distinctive advantages: high energy-conversion efficiencies (up to 70%) and a clean by-product, water. In the past decade, anion exchange membrane fuel cells (AEMFC), which convert chemical energy to electrical energy via the...

Holograms are everywhere, from driver's licenses to credit cards to product packaging. And now, edible holograms could someday enhance foods. Researchers reporting in ACS Nano have developed a laser-based method to print nanostructured holograms on dried corn syrup films. The edible holograms could also be used to ensure food safety, label a product or indicate sugar content, the researchers say.

Since Wilhelm Röntgen discovered them in 1895, X-rays have become a staple of medical imaging. In fact, barely a month after Röntgen's famous paper was published, doctors in Connecticut took the first ever radiograph of a boy's broken wrist.

Studies have shown that SARS-CoV-2 remains active on aerosols and surfaces for between several hours and several days, depending on the nature of the surface and environmental conditions. Presently, researchers from Tel Aviv University have demonstrated that ozone, which has already long been used as an antibacterial and antiviral agent in water treatment, effectively sanitizes surfaces against...

Wheat straw, the dried stalks left over from grain production, is a potential source of biofuels and commodity chemicals. But before straw can be converted to useful products by biorefineries, the polymers that make it up must be broken down into their building blocks. Now, researchers reporting in ACS Sustainable Chemistry & Engineering have found that microbes from the guts of certain termite...

Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change.

A mutation in the spike protein of SARS-CoV-2—one of several genetic mutations in the concerning variants that have emerged in the United Kingdom, South Africa, and Brazil—makes the virus up to eight times more infectious in human cells than the initial virus that originated in China, according to research published in the journal eLife.

Like a scene from a horror movie, tomato fruitworm caterpillars silence their food plants' cries for help as they devour their leaves. That is the finding of a multidisciplinary team of researchers, who said the results may yield insights into the abilities of crop plants—such as tomato and soybean—to withstand additional stressors, like climate change.

Researchers have developed an extremely sensitive miniaturized optical fiber sensor that could one day be used to measure small pressure changes in the body.

Polyisobutenyl succinic anhydrides (PIBSAs) are important for the auto industry because of their wide use in lubricant and fuel formulations. Their synthesis, however, requires high temperatures and, therefore, higher cost.

Scientists have used cutting-edge research in quantum computation and quantum technology to pioneer a radical new approach to determining how our Universe works at its most fundamental level.

In recent years, free digital world maps like OpenStreetMap (OSM) have become a vital instrument to support humanitarian missions over the entire world. In disaster management as well as the implementation of the United Nations Sustainability Development Goals (SDGs), geodata compiled by the volunteer mapper community open up new possibilities to coordinate aid interventions and carry out...

In a new study, Penn State researchers demonstrated that facilitating researcher-policymaker interactions in rapid response processes can influence both how legislators think about policy issues and how they draft legislation.

Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes—roughly 1.65 billion tons annually—make up about 16 percent of the total carbon that sinks below the ocean's upper layers.

In ancient European settlements, livestock use was likely primarily determined by political structure and market demands, according to a study published February 17, 2021 in the open-access journal PLOS ONE by Ariadna Nieto-Espinet and colleagues of the Consejo Superior de Investigaciones Científicas, Barcelona.

Paranapiacaba Treefrogs (Bokermannohyla astartea) mate and lay spawn in small pools of water inside the tanks of bromeliad plants, Leo Ramos Malagoli from the Universidade Estadual Paulista in Brazil and colleagues report in the open-access journal PLOS ONE. The 3cm-long tadpoles must then make their way to a stream to complete development. The study, publishing February 17, is the first to report...

Numerous studies have shown that trained dogs can detect many kinds of disease—including lung, breast, ovarian, bladder, and prostate cancers, and possibly COVID-19—simply through smell. In some cases, involving prostate cancer for example, the dogs had a 99 percent success rate in detecting the disease by sniffing patients' urine samples.

Lakes underneath the Antarctic ice sheet could be more hospitable than previously thought, allowing them to host more microbial life.
