A new bridge between the geometry of fractals and the dynamics of partial synchronization
In mathematics, simple equations can generate a complex evolution in time and intriguing patterns in space. One famous example of this is the Mandelbrot set, named after the French-American mathematician of Polish origin, Benoit B. Mandelbrot (1924-2.....»»
From transient to eternal: Probing equilibrium correlations by ramping dynamics
Prof. Jiazhong Hu at Tsinghua University and Prof. Xuzong Chen at Peking University, utilizing a new theory named non-adiabatic linear response proposed by Prof. Hui Zhai at Tsinghua University, experimentally demonstrate novel quasi-particle behavio.....»»
How selfishness can lead to fairness: Dynamics and risk sharing in groups of selfish individuals
In a study published in the Journal of Theoretical Biology, researchers used computer simulations to explore how herd animals can reduce their predation risk. The study is based on the idea suggested by W.D. Hamilton in 1971, that individuals in a he.....»»
Mapping molecular funnels with X-rays: Precise timings of non-adiabatic excited state dynamics
Time-resolved spectroscopy is a tool that provides access to the time-scale of chemical reactions as they happen. With the help of ultra-short light pulses, it is possible to observe conformal changes in molecules on the time-scale of the atomic moti.....»»

Understanding plants can boost wildland-fire modeling in an uncertain future
A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting......»»
Researchers complete first real-world study of Martian helicopter dust dynamics
Mars is a dusty planet. From tiny dust devils to vast storms that shroud the planet, dust is a constant challenge for research missions. That was especially true for Ingenuity, the rotorcraft that since February 2021 has been exploring Mars alongside.....»»
Satellite remote sensing helps monitor lake CO2 dynamics at large scale
Lakes play an essential role in carbon cycle. However, current bottom-up estimates of CO2 emissions from lakes have significant uncertainties due to insufficient field data......»»
Researchers uncover dynamics behind protein crucial in breast cancer
Watching a puppet show can teach you something about how estrogen works in the body, according to Rice University scientists whose research could open the door to new strategies for regulating the hormone—which could help prevent breast cancer an.....»»
Political orientation could be predicted by differences in brain activation and synchronization
A first-of-its-kind study scanned the brains of dozens of politically involved participants while they watched campaign-ads and speeches by parties from both ends of the political spectrum, just before one of the last rounds of elections. The partici.....»»
‘Nasty’ Geometry Breaks a Decades-Old Tiling Conjecture
Mathematicians predicted that if they imposed enough restrictions on how a shape might tile space, they could force a periodic pattern to emerge. They were wrong......»»
A new way to identify stresses in complex fluids
Fluid dynamics researchers use many techniques to study turbulent flows like ocean currents, or the swirling atmosphere of other planets. Arezoo Adrekani's team has discovered that a mathematical construct used in these fields provides valuable infor.....»»
Study reveals dynamics of DNA ligation during genome replication
Unconnected strands of DNA must be sealed together during genome replication and repair, and a new KAUST-led investigation shows how the fastening enzyme involved gets the job done......»»

Boston Dynamics’ Atlas robot grows a set of hands, attempts construction work
Atlas goes for "inertially significant" lifts, learns all about Newton's third law. "Give 'em the clamps!" Atlas now has a pair of gripper claws. It also may be time for a new.....»»
Upskilling people to interact with bots helps bridge the digital divide
Improving the public's ability to interact with bots will ensure that more humans have better experiences with commercial and public services that rely on bots, according to University of Surrey researchers......»»
Researchers find potential mechanism of solar light bridge formation and penumbra disappearance
Sunspots are the most noticeable manifestation of solar magnetic field concentrations in the photosphere. A typical mature sunspot has an umbra and a penumbra. Light bridges (LBs) are the strip-like bright features, two ends of which connect the penu.....»»
Understanding complex systems like the brain by analyzing the hidden geometry of their networks
A study published in Nature Communications and directed by Professor Carlo Vittorio Cannistraci, Director of the Center for Complex Network Intelligence (CCNI) at the Tsinghua Laboratory of Brain and Intelligence, proposes a fast algorithm to measure.....»»
Sun releases strong solar flare
The sun emitted a strong solar flare, peaking at 1:50 p.m. EST on Jan. 9, 2023. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured imagery of the event......»»
