Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»
Neutron-star mergers illuminate the mysteries of quark matter
Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a subsequent gravitational collapse. Although their collisions—or binary mergers—are rare, when they do occur, these violent eve.....»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»
AI, computation, and the folds of life: Supercomputers help train a software tool for the protein modeling community
Form follows function, and this is especially true for life's building blocks—proteins. The folds and shape of molecular proteins reveal their function in supporting life......»»
NASA demonstrates "ultra-cool" quantum sensor for first time in space
NASA's Cold Atom Lab, a first-of-its-kind facility aboard the International Space Station, has taken another step toward revolutionizing how quantum science can be used in space. Members of the science team measured subtle vibrations of the space sta.....»»
Modified solvents achieve vastly increased potentials for oxidation
A team of scientists headed by Professor Ingo Krossing, Professor of Molecular and Coordination Chemistry at the University of Freiburg's Institute of Inorganic and Analytical Chemistry, has succeeded in significantly increasing the potential for oxi.....»»

Researchers discover new material for optically-controlled magnetic memory
Researchers at the University of Chicago Pritzker School of Molecular Engineering (PME) have made unexpected progress toward developing a new optical memory that can quickly and energy-efficiently store and access computational data. While studying a.....»»
Researchers discover new mechanism to cool buildings while saving energy
With temperatures rising globally, the need for more sustainable cooling options is also growing. Researchers at UCLA and their colleagues have now found an affordable and scalable process to cool buildings in the summer and heat them in the winter......»»
A new mechanism for shaping animal tissues
A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, Germany, the Exce.....»»
The molecular shield: How tea plants combat drought through protein phosphorylation
Drought stress poses a significant challenge to agriculture, causing substantial yield losses in many crops. Tea plants, known for their rich flavonoid content which enhances both quality and health benefits, are particularly affected. Under drought.....»»
Increasing solid-state electrolyte conductivity and stability using helical structure
Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte—a solution that allows ions to move.....»»
Veterinarian says owners should be aware of the risks of letting their dogs drink from public water sources
When taking your dog for a walk during the scorching summer heat, it may be tempting to allow your dog a few laps from the nearest drinking station in order to cool off. However, shared hydration sources can potentially have dire effects for your bel.....»»
Study reveals how intermittent fasting regulates aging through autophagy
Recent research at the Institute of Molecular Biology and Biotechnology (IMBB) of the Foundation for Research and Technology-Hellas (FORTH), at the Paris Cité University, and at the University of Graz, published today in Nature Cell Biology, sheds l.....»»
Researchers calculate up to a billion birds may die in the US each year due to collisions with windows
A team of ornithologists from the Fordham University Graduate School of Arts and Sciences, the NYC Bird Alliance, Inc, and the Max Planck Institute for Geoanthropology has found evidence that far more birds are killed by window collisions than previo.....»»
Chemists develop new sustainable reaction for creating unique molecular building blocks
Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers ha.....»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
Breakthrough in molecular control: New bioinspired double helix with switchable chirality
The deoxyribonucleic acid or DNA, the molecular system that carries the genetic information of living organisms, can transcribe and amplify information using its two helical strands. Creating such artificial molecular systems that match or surpass DN.....»»
How the Olympics Are Saving Athletes from Heat Stress
Climate change-driven heat endangers Olympians. Here’s how the Games are helping competitors cool down.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
