The urgency of the global transition to a net-zero economy, focused on solutions that enable the reduction of greenhouse gas emissions, cannot be overstated. As both the engine of global economic growth and substantial emissions generator, industry has a unique responsibility and opportunity to lead this process. And while the energy and petrochemicals sectors have understandably been a central...
A new study from the University of Kansas shows that while journalists do use new technologies to better understand their audiences and what they would like to read, K-12 education reporters and editors still largely rely on gut feelings as opposed to analytics software, suggesting limitations to the practice.
Using NASA's Chandra X-ray observatory, astronomers have performed deep X-ray observations of a nearby active galaxy known as NGC 5728 and its active galactic nucleus (AGN). Results of the observational campaign, published March 1 on the pre-print server arXiv, deliver important information regarding the properties of this AGN and the emission from it.
At an excavation site in northern Mexico, BYU archaeology students and professors recently discovered artifacts that have been buried for 1,000 years, including pottery sherds, hammer stones, maize kernels and—intriguing at a location 250 miles inland—a shell bead from the Pacific Ocean.
On Feb. 23, researchers announced initial measurements from an experiment searching for the decay of metastable isomer tantalum-180. The measurements were based on the first 229 days of data-taking from the experiment located nearly a mile underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota.
Climate change is a global emergency challenging scientists, engineers, and industry experts from a wide array of disciplines to use their knowledge and skills in pursuit of solutions to protect our planet.
Researchers from Fudan University, China Europe International Business School, and Peking University published a new Journal of Marketing article that examines how marketers can use different messaging to persuade individuals to contribute to a collective goal. The study addresses the specific question of the type of message—fact-based vs. affected-based—that is more effective in eliciting...
For family members unexpectedly taking care of a relative's child during the opioid crisis, it can be difficult to navigate the legal waters of assuming custody. The process may be easier—and come with more support—if these caregivers have personal connections to local resource institutions, according to a study conducted by a Penn State faculty member.
It sounds like a party trick: Add water to the clear, licorice-flavored ouzo liquor, and watch it turn cloudy. This "ouzo effect" is an example of an easy way to make highly stable emulsions—or mixtures of liquids that don't like being together, like vinaigrettes—but nobody has yet fully understood how it works. Now, researchers report in ACS Central Science that the secret may lie in the...
NASA's Interstellar Boundary Explorer (IBEX) is fully operational after the mission team successfully reset the spacecraft on March 2.
An ensemble of microscopes, medical-style equipment, and other 3D scanners is providing insights that could help human and robotic explorers survive the harsh environments of deep space, the moon, Mars and beyond.
In places across the U.S., tree cover is shrinking—forests are burned by wildfires on the West Coast and drowned by rising sea levels along the East. From the ground, it's hard to assess the scale of the losses and the effects disappearing trees have on atmospheric carbon dioxide levels and climate change.
Mary L. Rigdon, director of the University of Arizona Center for the Philosophy of Freedom and an associate professor in the Department of Political Economy and Moral Science, has spent years studying gender competitiveness and women's equity. Her work challenges traditional stereotypes and makes a compelling business and ethical case to close the wage gap between men and women.
Researchers have found a way to predict the behavior of many-body quantum systems coupled to their environment. The work represents a way to protect quantum information in quantum devices, which is crucial for real-world applications of quantum technology.
New estimates suggest that plastic pollution in the oceans has risen dramatically since 2005.

Because the distance remaining to completing a goal plays a role in people's psychological state, their tendency to follow a persuasive message depends heavily on whether the message matches their psychological state of thinking or feeling.
People with chronic back pain may turn to spinal cord stimulation to ease their pain, but a Cochrane Review found no sustained benefits to the surgery that outweigh the costs and risks.
Contracting a lower respiratory tract infection in early childhood is associated with a higher risk of dying from respiratory disease as an adult, according to new research.
Short-distance migration, which accounts for the vast majority of migratory movements in the world, is crucial for climate change adaptation, according to new research. Contrary to common assumptions, most migratory movements are people moving short distances, largely due to economic, social and environmental factors, such as climate change.
Hunter-gatherers can help us understand the conditions that children may be psychologically adapted to because we lived as hunter-gatherers for 95% of our evolutionary history. And paying greater attention to hunter-gatherer childhoods may help economically developed countries improve education and wellbeing.
Having trouble sleeping? A new study examines the link between poor sleep and cardiovascular disease-free life expectancy.
Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of...
