Phys.org / Why promising CO₂-to-fuel catalysts keep falling short of copper
Technology that converts carbon dioxide (CO₂) into fuels and plastic feedstocks using electricity is gaining attention as a core technology in the era of carbon neutrality. In particular, ethylene and ethanol are high-value ...
Phys.org / Complexity isn't subjective—the right amount results in new material properties
Complexity may seem subjective, but a quantitative measure of the complexity of nanomaterials was recently developed by a team of researchers from the University of Michigan Engineering, the University of Southern California ...
Phys.org / Consistency check casts doubt on evolving dark energy
Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time. In a new analysis published ...
Phys.org / How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control ...
Phys.org / Bacteria found in artisan cheeses may ease disease
Blessed are the tiny cheesemakers: scientists have mapped out the bacteria responsible for giving three British cheeses their distinct flavor, which may also be beneficial to human health. Scientists in the Food Microbial ...
Phys.org / How does gold keep its glitter? Researchers uncover why it resists tarnish
Gold has been prized for thousands of years for its enduring shine, but Tulane University researchers have discovered that gold's resistance to tarnishing depends on more than its chemistry.
Phys.org / NASA's AWE instrument completes mission to study Earth's effect on space weather
On May 21, ground controllers powered down NASA's AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission.
Dialog / A new light-based sensor could help make ultrasensitive disease testing more portable
When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, ...
Phys.org / Television news coverage of climate policy is limited and polarized in the US, study finds
Two-thirds of Americans want action on climate change, but people vastly underestimate public support for climate solutions and policy. Historically, U.S. news outlets overrepresented views on climate change that went against ...
Phys.org / Evolutionary arms race stretches hawkmoths and flowers to extremes
Long before his days of research, Christian Couch was just a kid marveling at the butterflies in the Florida Museum of Natural History's Butterfly Rainforest. Years later, after enrolling as an undergraduate student at the ...
Medical Xpress / Sunscreen confusion puts more Americans at risk for Melanoma
Melanoma—the most serious form of skin cancer—doesn't just happen at the beach or in a tanning booth.
Phys.org / Hubble captures galaxy cluster MACS J1141.6-1905
Look closely at this image from NASA's Hubble Space Telescope and you'll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily ...
