Phys.org / Our ocean's 'natural antacids' may act faster than we thought
Earth's ocean absorbs carbon dioxide from the atmosphere, helping to temper the impact of climate change but increasing ocean acidity. However, calcium carbonate minerals found in the seabed act as a natural antacid: Higher ...
Phys.org / Bubble bots: Simple biocompatible microrobots autonomously target tumors
The potential of microrobots is enormous. These miniature objects can be designed to carry out actions within the body, such as sensing biomarkers, manipulating objects like blood clots, or delivering drug therapies to tumor ...
Phys.org / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Phys.org / Teen's 1958 find becomes Australia's oldest dinosaur fossil
University of Queensland research has confirmed Brisbane's only dinosaur fossil is Australia's oldest, dating back to the earliest part of the Late Triassic period 230 million years ago. The 18.5-centimeter footprint was ...
Phys.org / Complex tongue bones, fleshy teeth on the roof of earliest known bird's mouth might have helped it snag food
Flying is really hard work. Compared to walking, swimming, or running, flying is the form of movement that takes the most energy and requires the most calories. That means that birds have had to evolve specialized ways to ...
Phys.org / Real-time view inside microreactor reveals 2D semiconductor growth secrets
As the miniaturization of silicon-based semiconductor devices approaches fundamental physical limits, the electronics industry faces an urgent need for alternative materials that can deliver higher integration and lower power ...
Phys.org / Reshaping gold leads to new electronic and optical properties
By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light—and, as a result, its electronic and optical properties. This is shown by a study from ...
Phys.org / Banning lead in gas worked: The proof is in our hair
Prior to the establishment of the Environmental Protection Agency in 1970, Americans lived in communities awash with lead from industrial sources, paint, water supply pipes and, most significantly, tailpipe emissions. A dangerous ...
Phys.org / Tibet's tectonic clash: New satellite view suggests weaker fault lines
A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth's fault lines are far weaker and the continents are less rigid than scientists previously thought. This finding is based on ground-monitoring ...
Phys.org / Perseverance rover completes first AI-planned drive on Mars
NASA's Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency's Jet Propulsion Laboratory in Southern California, ...
Phys.org / New database reveals how Americans use water
Water powers our lives. It feeds our crops, keeps factories running, generates electricity, and fills our taps. But until now, no one had a clear, national picture of how much water we're using—and for what.
Phys.org / Unraveling the physics behind Kamchatka's 73-year earthquake cycle
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture ...
