Physicists harness electrons to make "synthetic dimensions"
Our spatial sense doesn't extend beyond the familiar three dimensions, but that doesn't stop scientists from playing with whatever lies beyond......»»
Climate model suggests extreme El Niño tipping point could be reached if global warming continues
A trio of physicists and oceanologists, two with the University of Cologne's Institute of Geophysics and Meteorology and the third with the GEOMAR Helmholtz Center for Ocean Research Kiel, all in Germany, has found via the CESM1 climate model that an.....»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
Physicists discover a way to imprint a previously unseen geometrical form of chirality onto electrons
Have you ever placed the palm of your left hand on the back of your right hand in such a way that all fingers point in the same direction? If you have, then you probably know that your left thumb will not touch its right counterpart. Neither rotation.....»»
Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
The geometry of life: Physicists determine what controls biofilm growth
From plaque sticking to teeth to scum on a pond, biofilms can be found nearly everywhere. These colonies of bacteria grow on implanted medical devices, our skin, contact lenses, and in our guts and lungs. They can be found in sewers and drainage syst.....»»
New Antikythera mechanism analysis challenges century-old assumption

Scientists develop new technique for bespoke optical tweezers
Scientists have developed a new way to trap small particles with light. Building on the Nobel Prize winning technique of optical tweezers (Arthur Ashkin, 2018), a team of physicists, led by Dr. David Phillips at the University of Exeter, has advanced.....»»
New shapes of photons open doors to advanced optical technologies
Researchers from the University of Twente in the Netherlands have gained important insights into photons, the elementary particles that make up light. They 'behave' in an amazingly greater variety than electrons surrounding atoms, while also being mu.....»»
Physicists report first measured isomeric-ratio in multinucleon-transfer reactions: A doorway to access terra incognita
Delving into the intricate properties of heavy neutron-rich nuclei is crucial since they have the potential to reshape our understanding of nuclear physics and astrophysics......»»
Scientists investigate fast reaction dynamics in synthetic molecules immobilized in porous protein cages
Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, report scientists from Tokyo Tech. By integrating this method with time-resolved seri.....»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
Physicists develop method to detect single-atom defects in semiconductors
One of the challenges of cramming smarter and more powerful electronics into ever-shrinking devices is developing the tools and techniques to analyze the materials that make them up with increasingly intimate precision......»»
3D covalent organic frameworks with zyg topology for photocatalytic synthesis of hydrogen peroxide
A research team proposed a new synthetic strategy of COFs based on a new topology that remotely separates donor (D) and acceptor (A) units in 3D lattice to produce the expected metastable photo-induced charge-separated states......»»
Unleashing the potential of high-spin polymers for next-gen optoelectronics and spintronics
The study of open-shell molecules, particularly those with high-spin ground states, has unveiled significant potential in organic electronics and magnetism. These molecules, characterized by unpaired electrons, exhibit unique properties such as long.....»»
Maintaining human oversight in AI-enhanced software development
In this Help Net Security interview, Martin Reynolds, Field CTO at Harness, discusses how AI can enhance the security of software development and deployment. However, increased reliance on AI-generated code introduces new risks, requiring human overs.....»»
Physicists explore how fluctuations shape transport networks
Understanding how transport networks, such as river systems, form and evolve is crucial to optimizing their stability and resilience. It turns out that networks are not all alike. Tree-like structures are adequate for transport, while networks contai.....»»
Pooping on the Moon Is a Messy Business
If humans are to return to the moon, space agencies and governments need to figure out the legal, ethical, and practical dimensions of extraterrestrial waste management......»»
