The first-ever study of the levels of the stress hormone cortisol in the saliva of newborn white-tailed deer fawns yielded thought-provoking results that have Penn State researchers suggesting predation is not the only thing in the wild killing fawns.
Would you like to capture a chemical transformation inside a cell live? Or maybe revolutionize microchips' production by printing paths in a layer that has a thickness of just 100 nanometers? These and many other goals can now be achieved with the latest femtosecond laser created by a team of scientists led by Dr. Yuriy Stepanenko.
The study found a "systematic and quantifiable pattern" of political parties officers opting against fielding minority candidates where they perceive that their non-white appearance might prevent a win. This includes constituencies already held by the party, and those within reach, requiring just a small swing in the vote to change hands.
Scientists from the University of Bath have made a sustainable polymer using the second most abundant sugar in nature, xylose.
A sweet new process is making sour more practical.
A team led by University of Minnesota Twin Cities researchers has discovered a groundbreaking one-step process for creating materials with unique properties, called metamaterials. Their results show the realistic possibility of designing similar self-assembled structures with the potential of creating "built-to-order" nanostructures for wide application in electronics and optical devices.
Karl Schwartz wishes he was simply chasing glory on the snowmobile racing track. Instead, in recent years, he has been forced to chase increasingly elusive cold weather.
Fewer than 1% of people globally live in truly remote hinterlands, sharpening the need for better understanding of how urban forms impact food systems as well as social and economic development, according to ground-breaking new research by the Food and Agriculture Organization of the United Nations and the University of Twente.
In a new study, Stanford researchers report that intensifying precipitation contributed one-third of the financial costs of flooding in the United States over the past three decades, totaling almost $75 billion of the estimated $199 billion in flood damages from 1988 to 2017.
The large mollusk known as the California mussel makes its home in the rocky shoreline along the Pacific Coast from Mexico to Alaska. Considered a "foundational" animal, Mytilus californianus provides homes for hundreds of other species and offers a rich food source for species ranging from spiny lobsters to humans.
Prime Minister Justin Trudeau today announced that Canada would commit up to $55 million to a United Nations initiative aimed at preventing further degradation of land and protecting vital...
Rice University engineers hope to make life better for those with replacement joints by modeling how artificial hips are likely to rub them the wrong way.
University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals—everything from illicit drugs to pollution—as quickly as a breathalyzer identifies alcohol.
Scientists crafting a nickel-based catalyst used in making hydrogen fuel built it one atomic layer at a time to gain full control over its chemical properties. But the finished material didn't behave as they expected: As one version of the catalyst went about its work, the top-most layer of atoms rearranged to form a new pattern, as if the square tiles that cover a floor had suddenly changed to...
An atypical two-dimensional sandwich has the tasty part on the outside for scientists and engineers developing multifunctional nanodevices.
Mindfulness courses can reduce anxiety, depression and stress and increase mental wellbeing within most but not all non-clinical settings, say a team of researchers. They also found that mindfulness may be no better than other practices aimed at improving mental health and wellbeing.
A researcher finds that stress on an expectant mother could affect her baby's chance of developing disease -- perhaps even over the course of the child's life.

Pregnant women who exercise more during the first trimester of pregnancy may have a lower risk of developing gestational diabetes, according to a new study. The analysis found that lower risk was associated with at least 38 minutes of moderate intensity exercise each day -- more than current recommendations of at least 30 minutes a day five days a week.
A unique two-dimensional material shows distinct properties on each side, depending on polarization by an external electric field. The pairing of antimony and indium selenide could have applications in solar energy and quantum computing.
A shapeshifting immune system protein called XCL1 evolved from a single-shape ancestor hundreds of millions of years ago. Now, researchers at the Medical College of Wisconsin (MCW) discovered the molecular basis for how this happened. In the process they uncovered principles that scientists can use to design purpose-built nanoscale transformers for use as biosensors, components of molecular...
Many policymakers and educational institutions hope to boost their economies by stimulating students' entrepreneurial intentions. To date, most research concluded that entrepreneurship education could increase these intentions by improving the image that students have of entrepreneurship as a career option, making them see how their environment can help them become entrepreneurs or increasing...
Concrete has become our building material of choice for countless structures such as bridges, towers and dams. But it also has a huge environmental footprint mostly due to carbon dioxide emissions from the production of cement—one of its main constituents. Researchers are now experimenting with root vegetables and recycled plastic in concrete to see whether this can make it stronger—and more...

When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately engineering the surface to take advantage of this phenomenon offers a way to design better catalysts.
A team of scientists has developed a bio-compatible surgical patch that releases non-opioid painkillers directly to the site of a wound for days and then dissolves away. The polymer patch provides a controlled release of a drug that blocks the enzyme COX-2 (cyclooxygenase-2,) which drives pain and inflammation.
A sweet new process is making sour more practical. Engineers are turning carbon monoxide directly into acetic acid -- the widely used chemical agent that gives vinegar its tang -- with a continuous catalytic reactor that can use renewable electricity efficiently to turn out a highly purified product.
Scientists have made a sustainable polymer using the second most abundant sugar in nature, xylose.
An international team of researchers, including Professor Roberto Morandotti of the Institut national de la recherche scientifique (INRS), just introduced a new photonic processor that could revolutionize artificial intelligence, as reported by the prestigious journal Nature.
