How ultracold, superdense atoms become invisible
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli.....»»
Physicists See "Strange Matter" Form inside Atomic Nuclei
New research attempts to discern how bizarre particles of strange matter form in the nuclei of atoms.....»»
Newly observed effect makes atoms transparent to certain frequencies of light
A newly discovered phenomenon dubbed "collectively induced transparency" (CIT) causes groups of atoms to abruptly stop reflecting light at specific frequencies......»»
Discovering hidden order in disordered crystals
Researchers at Tokyo Tech have discovered hidden chemical order of the Mo and Nb atoms in disordered Ba7Nb4MoO20, by combining state-of-the-art techniques, including resonant X-ray diffraction and solid-state nuclear magnetic resonance. This study pr.....»»
A highly precise terahertz molecular clock
In recent years, many physicists worldwide have introduced atomic clocks, systems to measure the passing of time that are based on quantum states of atoms. These clocks can have numerous valuable applications, for instance in the development of satel.....»»
CISOs: unsupported, unheard, and invisible
A study conducted among CISOs worldwide from various industries sheds light on their strategies amid a challenging threat environment, identifies obstacles from business functions, and highlights their requirements for achieving success. “Our resea.....»»
YouTuber Marques Brownlee gets into the sneaker game with high tops for Atoms
The sneaker is called “251” in honor of the duration Brownlee’s first YouTube video. Marques Brownlee never thought he would design a sneaker.Read Full Story.....»»
How physicist Sameera Moussa went from a role model to a target
Research success and "Atoms for Peace" activism left Sameera Moussa a murder victim. Enlarge (credit: Aurich Lawson | Wikipedia) Science and the technology it enables have always had a close relationship with warfare. Bu.....»»
Simulations with a machine learning model predict a new phase of solid hydrogen
Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are als.....»»
Scientists discover pre-low-mass white dwarf binary using LAMOST
A binary system containing an extremely low-mass (ELM) white dwarf (WD) progenitor and a compact invisible companion, was discovered by Chinese astronomers from the National Astronomical Observatories of Chinese Academy of Sciences (NAOC), using spec.....»»
New look at "Einstein rings" around distant galaxies just got us closer to solving the dark matter debate
Physicists believe most of the matter in the universe is made up of an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see......»»
Researchers image magnetic behavior at the smallest scales to date
Permanent magnets, the kind found on refrigerators everywhere, exist because their constituent atoms behave as miniature magnets. They align and combine to form the larger magnet in a phenomenon called ferromagnetism. There are some materials where t.....»»
The Big Bang"s Afterglow Reveals Invisible Cosmic Structures
Scientists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter......»»
A new quantum approach to solve electronic structures of complex materials
If you know the atoms that compose a particular molecule or solid material, the interactions between those atoms can be determined computationally, by solving quantum mechanical equations—at least, if the molecule is small and simple. However, solv.....»»
A new model predicts the flexibility of DNA movement at the molecular scale
In both physics and chemistry, the mesoscopic scale refers to the length scale on which the properties of a material or phenomenon can be studied, without entering into a discussion about the behavior of individual atoms. In a mesoscopic model, atomi.....»»
Highly charged ions melt nano gold nuggets
Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The world of small but not yet ti.....»»
Habitat will dictate whether ground beetles win or lose against climate change, finds study
The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web—ground beetles. Nearly 2,000 species of ground beetle live in North America. New research led by Pennsylvania State.....»»
The journey of a carbon atom: From space, NASA"s PACE mission detects carbon in the sky, land and sea
Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission—schedule.....»»
Study sheds light on ancient microbial dark matter
Bacteria are literally everywhere—in oceans, in soils, in extreme environments like hot springs, and even alongside and inside other organisms including humans. They're nearly invisible, yet they play a big role in almost every facet of life on Ear.....»»
High-loading single cobalt atoms on ultrathin MOF nanosheets for efficient photocatalytic carbon dioxide reduction
Using solar energy to convert CO2 into synthetic fuels is currently one of the most promising technologies to achieve carbon neutrality with the embedment of sustainable energy into our modern economy. However, the efficiency of photocatalytic CO2 co.....»»
Apple Watch finds invisible heart condition for 36-year-old author: ‘It’s not a feature I’d ever expected to use’
A new report from the BBC highlights what is only the latest instance of a person’s Apple Watch alerting them to a potentially deadly heart condition. Adam Croft, a 36-year-old from Bedfordshire, recounted the experience: “It’s not a feature I.....»»
