Phys.org / Marsquakes indicate a solid core for the red planet, just like Earth
Scientists revealed Wednesday that Mars' innermost core appears to be a solid hunk of metal just like Earth's.
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 / Juno finds final missing auroral signature from Jupiter's largest moons
Jupiter hosts the brightest and most spectacular auroras in the solar system. Near its poles, these shimmering lights offer a glimpse into how the planet interacts with the solar wind and moons swept by Jupiter's magnetic ...
Phys.org / Algorithms that address malicious noise could result in more accurate, dependable quantum computing
Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data inherently "noisy." Rice University computer scientists have developed algorithms that account for noise ...
Phys.org / Fossil fish sheds new light on extra teeth evolution to devour prey
Experts have uncovered the earliest known example of a fish with extra teeth deep inside its mouth—a 310-million-year-old fossilized ray-finned fish that evolved a unique way of devouring prey.
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 / 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 ...
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 / 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.
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 ...
