Discovering new energy levels in atomic hyperfine structures
Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the development of Fourier transform spectroscopy, and t.....»»
Unveiling the hottest period in a million years: The MIS 11c paradox
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a ke.....»»
Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator
Inside the next generation of fusion vessels known as spherical tokamaks, scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) envisioned a hot region with flowing liquid metal that is reminiscent of a subterranean.....»»
OpenCTI: Open-source cyber threat intelligence platform
OpenCTI is an open-source platform designed to help organizations manage their cyber threat intelligence (CTI) data and observables. The platform structures its data using a knowledge schema built on the STIX2 standards. It features a modern web appl.....»»
Advanced materials could provide more durable metals for fusion power reactors
For many decades, nuclear fusion power has been viewed as the ultimate energy source. A fusion power plant could generate carbon-free energy at a scale needed to address climate change. And it could be fueled by deuterium recovered from an essentiall.....»»
Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typicall.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
This year’s summer COVID wave is big; FDA may green-light COVID shots early

Achieving enhanced energy storage performance and ultra-fast discharge time in tungsten-bronze ceramic
It is widely recognized that achieving high energy storage density and efficiency in ferroelectric ceramics relies on their ability to exhibit high saturation polarization and low residual polarization, which are essential for excellent energy storag.....»»
Scientists propose gliding arc discharge plasma seawater sterilization technology for mariculture
Atmospheric pressure plasma technology has demonstrated vast potential in microbial inactivation due to its unique advantages, including no chemical residue, environmental friendliness, high treatment efficiency, low energy consumption and ease of us.....»»
Going slow is better for fast cycling: Study reveals unique replication fork behavior in pluripotent stem cells
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report published in E.....»»
Morphable materials: Researchers coax nanoparticles to reconfigure themselves
A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, a.....»»
Scientists uncover exciton behavior in van der Waals magnets
A research group led by scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has uncovered details about the formation and behavior of mobile, microscopic, particle-like objects called "excitons" in a class of materials.....»»
Energy companies pressure landowners into fracking, study shows
Energy companies use persistent and personalized pressure to get landowners to give permission for hydraulic fracturing (fracking), and even when landowners decline, companies use legalized compulsion to conduct fracking anyway, according to a new st.....»»
Scientists discover phenomenon impacting Earth"s radiation belts
Two University of Alaska Fairbanks scientists have discovered a new type of "whistler," an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere......»»
Unveiling the power of hot carriers in plasmonic nanostructures
A new scientific review explores the exciting potential of hot carriers, energetic electrons generated by light in plasmonic nanostructures. These tiny structures hold immense promise for future technologies due to their unique way of interacting wit.....»»
