Scientists unveil latest femtosecond laser

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.

Researchers develop new one-step process for creating self-assembled metamaterials

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.

Climate change has caused billions of dollars in flood damages

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.

Ocean acidification is transforming California mussel shells

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.

Study shows tweaking one layer of atoms on a catalyst's surface can make it work better

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...

Increased first-trimester exercise may reduce gestational diabetes risk

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.

2D compound shows unique versatility

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.

Cracking the code of a shapeshifting protein

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...

Instead of pushing students toward entrepreneurship, they should be helped with understanding personal priorities

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...

Carrot cement: How root vegetables and ash could make concrete more sustainable

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...

'Reckless' Christmas easing of rules blamed for Ireland Covid surge

Country has world’s highest rate of infection with critics blaming socialising over festive periodCoronavirus – latest updatesSee all our coronavirus coverageIreland emerged from a six-week lockdown in early December with the European Union’s lowest coronavirus infection rate.It eased restrictions in belief it could contain a rise in the virus over Christmas unlike, say, Germany and the UK,...

In the process they uncovered principles that scientists can use to design purpose-built nanoscale transformers for use as biosensors, components of molecular machines, and even therapeutics.

Carbon monoxide reduced to valuable liquid fuels

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.

Using light to revolutionize artificial intelligence

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.
