Phys.org / MOF-coated catalyst converts CO₂ to CO nearly five times faster under ultrasonic vibration
Researchers at the University of Osaka have developed a catalyst that uses mechanical vibration to convert carbon dioxide (CO2) into carbon monoxide (CO), an important chemical feedstock. The catalyst consists of barium titanate ...
Phys.org / Venus's mysterious clouds may hide an exceptionally strong light absorber
Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet's upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, ...
Phys.org / Parasitic plants act like genetic engineers by stealing and remodeling useful genes
Many plant species parasitize other plants by latching on and taking the nutrients their hosts need to survive. But sometimes, plants steal more than nutrients; they take genes.
Phys.org / How bacteria develop resistance to programmable antibiotics
Antimicrobial resistance is one of the greatest challenges facing modern medicine. A new class of programmable antibiotics known as asobiotics can be used to treat bacterial infections when classical antibiotics fail. A team ...
Phys.org / Degraded DNA reveals two extinct Galapagos giant tortoise lineages
Using a new combination of computational tools to analyze ancient DNA, Yale researchers have discovered two ancient, extinct giant tortoise lineages that once lived on the Galapagos Islands.
Phys.org / The wisdom of the egg cell: Oocyte epigenetic mark may help prevent excessive placental growth after fertilization
The genome—which contains genes encoded in DNA—acts as the fundamental blueprint of life. But what you might not know is that, in addition to this genetic information, we have something akin to an "instruction manual" for ...
Phys.org / Heat-tolerant corals may be more vulnerable to disease
Corals that partner with heat-tolerant algae may be better equipped to survive warming oceans—but that resilience comes with an unexpected trade-off, according to a new study from Boston University published in Science Advances.
Phys.org / Some Galápagos 'yellow' sea turtles remain homebodies, surprising scientists
Sea turtles are famous for being prodigious wanderers. Guided by Earth's magnetic field, ocean currents and the sun, they tend to crisscross the seas in search of food, returning to the region of their birth every few years ...
Phys.org / Tomatoes get flavor boost from green bin compost
Commercially farmed tomatoes taste sweeter when food and garden waste compost is added to their soil, a University of Queensland study has found. Researchers in the School of Agriculture and Food Sustainability grew tomatoes ...
Phys.org / Beyond the Petri dish: Testing tomorrow's drugs in human blood
The COVID vaccine is perhaps the first thing many people think of when they hear about mRNA-based drugs. Small packages of genetic material are sent into the body, prompting cells to produce useful proteins in the fight against ...
Phys.org / Using AI to thwart election misinformation
Election rumors, such as unverified accounts of voter fraud, have run rampant in the U.S. in recent years. Powered by the speed of social media and artificial intelligence (AI), it can be hard for people to know what messages ...
Phys.org / 'Like uprooting tree stumps'—pulling nanoscale anchors creates tiny pores that could speed biosensor manufacturing
A new manufacturing method could help move the production of nanoscale sensors from specialized fabrication facilities to conventional semiconductor manufacturing plants.Publishing in Science Advances, researchers from KTH ...
