Cooling speeds up electrons in bacterial nanowires
The ground beneath our feet and under the ocean floor is an electrically-charged grid, the product of bacteria "exhaling" excess electrons through tiny nanowires in an environment lacking oxygen......»»
First visualization of valence electrons reveals fundamental nature of chemical bonding
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence.....»»
Chalk-based coating creates a cooling fabric
In the scorching heat of summer, anyone who spends time outside—athletes, landscapers, kids at the park or beachgoers—could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or transfer heat away from the bo.....»»
Ancient civilizations had ways to counter the urban heat island effect—how history"s lessons apply to cities today
As intense heat breaks records around the world, a little-reported fact offers some hope for cooling down cities: Under even the most intense periods of extreme heat, some city blocks never experience heat wave temperatures......»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
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.....»»
Physicists uncover new phenomena in fractional quantum Hall effects
Imagine a two-dimensional flatland, instead of our three-dimensional world, where the rules of physics are turned on their head and particles like electrons defy expectations to reveal new secrets. That's exactly what a team of researchers, including.....»»
Theoretical research holds promise for advancing modular quantum information processing
The operation of a quantum computer relies on encoding and processing information in the form of quantum bits—defined by two states of quantum systems such as electrons and photons. Unlike binary bits used in classical computers, quantum bits can e.....»»
Surprise finding in study of environmental bacteria could advance search for better antibiotics
In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial.....»»
Light-responsive gene regulation at the mRNA level
Researchers at the University of Bayreuth have established a new optogenetic approach that can control the bacterial production of proteins at the mRNA level using blue light. The new system gates the activation of the genetic substance particularly.....»»
"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.....»»
Nearly 25,000 Cadillac Lyriq EVs recalled for braking software glitch
Antilock braking system may activate at low speeds, increasing crash risk......»»
Studying the skin of the great white shark could help reduce drag in aircraft
High-ridged dentricles reduce drag at low speeds; alternating ridges do so at high speeds. Enlarge / Great white sharks can reduce drag at different swimming speeds thanks to high and low ridged dentricles in its skin. (credit: T.....»»
Align or die: Revealing unknown mechanism essential for bacterial cell division
A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto "dying to align": Misaligned filaments "die" spontaneously to form a ring structure at the center of the dividing cell. The stud.....»»
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......»»
From fungi to pharmaceuticals: A milestone for the production of eutyscoparol A and violaceoid C
The natural world is rich in chemical compounds with remarkable medicinal properties. A notable example is penicillin, discovered by chance from the Penicillium mold. This discovery revolutionized the treatment of bacterial infections and highlighted.....»»
Home Depot expands Hubspace with an intelligent bathroom fan
The Commercial Electric Smart Exhaust Fan works with most smart home platforms while also offering built-in lights, two fan speeds, and a Bluetooth speaker......»»
Bacterial gut diversity improves the athletic performance of racehorses
The composition of gut bacteria of thoroughbred racehorses at one month old can predict their future athletic performance, according to a new study from the University of Surrey. In the study, foals with lower bacterial diversity at 28 days old also.....»»
The best SSDs for 2024
The best SSDs deliver the fastest read and write speeds on the market in a durable, compact package. Here are the best and why these cards make great upgrades......»»
The next SSDs may be over 80% faster
Micron just unveiled its next-gen PCIe 6.0 SSD which will reportedly reach speeds of over 26GB/s. That's a massive increase over PCIe 5.0, but there's a catch......»»
Giant pangolin rediscovered in Senegal
In March 2023, temperatures in eastern Senegal soared to 40°C, with the cooling rains still months away. Yet, for the dedicated field team from the NGO Panthera—committed to global feline conservation—and the Direction des parcs nationaux du Sé.....»»
