Phys.org / Computational model extends the study of nanostructures beyond classic layered systems
Since the production of graphene in 2004, two-dimensional materials have been sparking scientific and technological interest. As they are only a few atomic layers thick, or even just a single atomic layer, they can exhibit ...
Phys.org / SPINE: A machine-learning program is on the trail of ghost particles
Neutrinos are among the most abundant particles in the universe, but they are also among the most elusive. Nearly massless, they are produced by nuclear reactions in the sun, exploding stars, particle accelerators and even ...
Phys.org / Greenhouse gas levels hit new record highs in 2025: UN
Greenhouse gas concentrations in the atmosphere rose to new record highs in 2025, locking in climate impacts that will persist for centuries to come, the United Nations said Tuesday.
Phys.org / Autonomous rendezvous system overcomes simulated spacecraft failures in lab tests
There is a problem in low Earth orbit, and it's growing. According to the European Space Agency, there are about 19,440 satellites on orbit, 3,540 of which are nonfunctioning and/or not emitting a signal to warn other spacecraft ...
Phys.org / Light-controlled brake makes random molecular motion 300,000 times slower
Molecules are never still. Driven by thermal energy, they are constantly moving through space, while their individual parts also rotate relative to one another. Scientists at IOCB Prague have now shown that random motion ...
Phys.org / Identical vesicles, different behaviors: Model reveals how spontaneous asymmetry gives rise to lifelike behavior
In nonreciprocal active matter, agents act differently on each other, seemingly in violation of Newton's third law. This principle can result in various active matter traits, such as self-propulsion, molecular regulation ...
Phys.org / Tiny droplets use pressure to unlock new routes to degradable plastics
Using a new technique, a research group led by Osaka Metropolitan University (OMU) has substantially increased the range of plastics that can be degraded naturally. The study is published in the journal Macromolecules.
Phys.org / Ancient fault suggests earthquake heating may amplify tsunami-triggering slip
In 2011, a huge earthquake struck eastern Japan. The magnitude 9.1 earthquake caused shaking at its epicenter for almost six minutes. However, its effects didn't end there, as the movement of the plates displaced the seafloor ...
Phys.org / A 'simple recipe' takes some of the guesswork out of mass spectrometry imaging
A small sample of human tissue can hold a remarkable amount of information. Researchers can use it to search for molecular clues associated with cancer, investigate the chemical landscape of the brain or determine where a ...
Phys.org / Microscopic springs transform fragile silicon into a flexible terahertz metamaterial
Researchers at the Osaka Research Institute of Industrial Science and Technology (ORIST), in collaboration with the University of Osaka and Tohoku University, have developed a flexible and stretchable silicon material whose ...
Phys.org / Reusable palladium catalyst enables more direct chemical synthesis
Making complex molecules often means joining smaller chemical building blocks together, a process facilitated by catalysts, compounds that make such reactions possible or speed them up without being consumed themselves. Many ...
Phys.org / Urban infrastructure grows more slowly than population, global analysis finds
As cities grow in population, they grow proportionally in terms of infrastructure—new buildings, paved streets and parking lots. Or so says conventional wisdom. However, a new study by a team of New York University researchers ...
