Phys.org / Global methane levels continue rising as trade and developing regions fuel growth
The world's methane emissions continue to rise steadily with no signs of slowing, as global trade contributes some 30% to the total amount of the greenhouse gas swirling around the planet, a new study reveals.
Phys.org / Crystalline material conducts heat even worse than glass and water—and that's promising
A research team from Aarhus University, Denmark, has measured and explained the exceptionally low thermal conductivity of the crystalline material AgGaGe3Se8. Despite its ordered structure, the material behaves like a glass ...
Phys.org / Nutrient-enriched seagrass can store more carbon, but too much nutrition—especially nitrogen—can be its undoing
Seagrass has the potential to be one of the world's most effective sponges at soaking up and storing carbon, but we don't yet know how nutrient pollution affects its ability to sequester carbon.
Phys.org / Soot's climate-altering properties change within hours of entering atmosphere
Billions upon billions of soot particles enter Earth's atmosphere each second, totaling about 5.8 million metric tons a year—posing a climate-warming impact previously estimated at almost one-third that of carbon dioxide.
Phys.org / Sperm bots roll out: Cells coated with magnetic nanoparticles could transform future of fertility
A team of researchers at the TechMed Center of the University of Twente has transformed real sperm cells into tiny, magnetically controlled microrobots. These sperm bots can now be tracked in real time using X-ray imaging, ...
Phys.org / Hybrid nanotube electrodes developed for safer brain-machine interfaces
Brain–computer interfaces are technologies that enable direct communication between brain activity and external devices, enabling researchers to monitor and interpret brain signals in real time. These connections often ...
Dialog / A light-programmable, dynamic ultrasound wavefront
The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion holds particularly true ...
Phys.org / Despite cloudy skies, bees can still use sun for navigation
The hunt for nectar can take honeybees kilometers away from their hive into unknown territory—and yet, they always find their way back. The sun's position in the sky serves as a kind of compass for bees, even when clouds ...
Phys.org / Climate change is making rollercoaster harvests the new normal
A new global study led by the University of British Columbia shows that hotter and drier conditions are making food production more volatile, with crop yields swinging more sharply from year to year. For some, it may mean ...
Phys.org / Hidden step in hemoglobin's carbon monoxide release challenges long-held assumption
Researchers have made a groundbreaking discovery about hemoglobin, the protein responsible for carrying oxygen throughout the body. The findings challenge decades of scientific assumptions and provide new insights into fundamental ...
Phys.org / Standardized approach replicates microplastics in the lab with greater precision
McGill University researchers have developed a novel method to replicate four types of microplastics commonly found in the environment, providing researchers with a standardized approach to study their toxic effects.
Phys.org / Countries' carbon budget math is broken—study finds bias in calculations
Climate action is falling behind on the goals as stated in the Paris Agreement. To meet those goals, countries must act according to their "fair share" targets. However, researchers from Utrecht University found a bias in ...
