Use of "clean" hydrogen has been seen as a viable and environmentally benign energy alternative, but a study released Thursday said it could lead to higher greenhouse gas emissions than coal.

A multi-year study on automated transit fare collection offers a key finding that won't surprise you: Despite the convenience, the rush toward cashless fare systems has created barriers for lower-income riders seeking to use transit. Results from focus groups, surveys, and a review of current transit agency practices suggest that continuing to accept cash is a crucial way to keep transit...

Stock trading volumes in the United States have soared over the last year and much of it seems to be driven by retail investors. With thousands of stocks to choose from, what factors influence investors' decisions?

On Aug. 9, 2021, ESA/NASA's Solar Orbiter spacecraft passed within 4,967 miles (7,995 kilometers) of the surface of planet Venus. In the days leading up to the approach, the Solar Orbiter Heliospheric Imager, or SoloHI, telescope captured this gleaming view of the planet.

A team of scientists has discovered a new marmoset species in the Brazilian Amazon. Schneider's marmoset (Mico schneideri), described in the latest issue of the journal Scientific Reports, is named after professor Horacio Schneider, a pioneer and major contributor to the research of diversity and evolution of monkeys.

Polycentric development is being promoted to lessen problems of urban sprawl and reduce vehicle miles traveled (VMT). A new article published in the August 2021 issue of Applied Geography examines the difference between "morphological" and "functional" polycentricity in the Wasatch Front Region of Utah.

Quantum entanglement is one of the most fundamental and intriguing phenomena in nature. Recent research on entanglement has proven to be a valuable resource for quantum communication and information processing. Now, scientists from Japan have discovered a stable quantum entangled state of two protons on a silicon surface, opening doors to an organic union of classical and quantum computing...

Photocatalysts absorb energy from light to make a chemical reaction happen. The best known photocatalyst is perhaps chlorophyll, the green pigment in plants that helps turn sunlight into carbohydrates. While carbohydrates may be falling out of favor, photocatalysis is garnering more attention than ever. In a photocatalytic process, light falls on a photocatalyst, increases the energy of its...

Russia's top criminal investigation agency on Thursday probed an oil spill off the country's Black Sea coast that appeared hugely bigger than initially reported.

In addition to being visually stunning, schools of herring, herds of wildebeest and countless other groups of organisms that act in concert can help complex ecosystems maintain their diversity and stability, new research by Oregon State University shows.

Researchers at CU Boulder are part of a newly published study that finds that low-rise, high-density environments like those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle.

Researchers have developed an innovative technique for creating nanomaterials. These are materials only atoms wide. They draw on nanoscience to allow scientists to control their construction and behavior. The new electron beam nanofabrication technique, plasmon engineering, achieves unprecedented near-atomic scale control of patterning in silicon. Structures built using this approach produce...

Finding animals in the wild can be tough, even for researchers with access to airplanes, high-end cameras and other costly gear.

Despite the challenges of distance learning during the pandemic, public school systems across the U.S. are setting up virtual academies in growing numbers to accommodate families who feel remote instruction works best for their children.

Volunteers and county employees set up cots and stacked hundreds of bottles of water in an air-conditioned cooling center in a vacant building in Portland, Oregon, one of many such places being set up as the Northwest sees another stretch of sizzling temperatures.

The feeding patterns of black holes offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass.

The world may need to start thinking differently about plants, according to a new report in the journal Science by researchers who took a fresh look at spore-like microfossils with characteristics that challenge our conventional understanding about the evolution of land plants.

By discovering previously unexplored ways in which crop pathogens break through plant cell walls, the scientists have opened up opportunities for developing effective disease control technologies.

An international research team has retraced the astonishing lifetime journey of an Arctic woolly mammoth, which covered enough of the Alaska landscape during its 28 years to almost circle the Earth twice.

Trees fall every day in São Paulo, Brazil, the largest and most populous city in Latin America, but most tree falls occur in the rainy season owing mainly to the effects of temperature, strong winds and heavy rain. When trees fall in the dry season, the main direct cause is not weather but a lack of management and adequate conditions for the survival of street vegetation.

One of the most important optimisation goals underlying the Wendelstein 7-X fusion device at Max Planck Institute for Plasma Physics (IPP) in Greifswald has now been confirmed. An analysis by IPP scientists in the journal Nature shows: In the optimized magnetic field cage, the energy losses of the plasma are reduced in the desired way. Wendelstein 7-X is intended to prove that the disadvantages of...

A radical collaboration between a biologist and an engineer is supercharging efforts to protect grape crops. The technology they've developed, using robotics and AI to identify grape plants infected with a devastating fungus, will soon be available to researchers nationwide working on a wide array of plant and animal research.

As NASA prepares for its "next giant leap"—meaning astronauts on Mars—technology developed by Austin-based 3D printing construction company Icon is helping pave the way.

Three dinosaurs from Northwest China represent two new species and are some of the first vertebrates uncovered in the region, according to a study published in Scientific Reports. The findings shed light on sauropods in China.
