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......»»
X-ray spectroscopy study maps ultrafast charge delocalization in aqueous environments
The movement of electron density is a subject of interest for chemists worldwide, as substances interact through electrons. These processes are ultrafast and traditionally require time-resolved experiments at the attosecond level to study and describ.....»»
Structural biology analysis of a Pseudomonas bacterial virus reveals a genome ejection motor
The viruses that infect bacteria are the most abundant biological entities on the planet. For example, a recent simple study of 92 showerheads and 36 toothbrushes from American bathrooms found more than 600 types of bacterial viruses, commonly called.....»»
I tested the battery life of 3 popular smartwatches, and the results surprised me
The Apple Watch Series 10, Pixel Watch 3, and Galaxy Watch 7 are three of the year's biggest smartwatches. Which has the best battery life and charge speeds?.....»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»

Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
More efficient phenotypic screening method can simultaneously test multiple drugs
Some of the most widely used drugs today, including penicillin, were discovered through a process called phenotypic screening. Using this method, scientists are essentially throwing drugs at a problem—for example, when attempting to stop bacterial.....»»
Next-gen 6G cellular networks may be 9,000 times faster than 5G
New reports indicate that next-generation wireless networks could achieve speeds of up to 938 gigabits per second, roughly 9,000 times the speed of current 5G … The post Next-gen 6G cellular networks may be 9,000 times faster than 5G appeared f.....»»
EarthCARE synergy reveals power of clouds and aerosols
With the initial images from each of the instruments aboard ESA's EarthCARE satellite now in hand, it's time to reveal how these four advanced sensors work in synergy to measure exactly how clouds and aerosols influence the heating and cooling of our.....»»
Targeting bacteria: Auxiliary metabolic genes expand understanding of phages and their reprogramming strategy
Viruses that infect bacteria—known as bacteriophages—could be used in a targeted manner to combat bacterial diseases. They also play an important ecological role in global biogeochemical cycles. Recent research by researchers at the University of.....»»
Ancient climate analysis reveals unknown global processes
According to highly cited conventional models, cooling and a major drop in sea levels about 34 million years ago should have led to widespread continental erosion and deposited gargantuan amounts of sandy material onto the ocean floor. This was, afte.....»»
"Killer electrons": Lightning storms play cosmic pinball with space weather
When lightning strikes, the electrons come pouring down. In a new study, researchers at the University of Colorado Boulder, led by an undergraduate student, have discovered a novel connection between weather on Earth and space weather. The team utili.....»»
World"s highest-voltage gun accelerates electrons from zero to 80% the speed of light
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed and tested the world's highest voltage polarized electron gun, a key piece of technology needed for building the world's first fully polarized Electron-I.....»»
Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooli.....»»
Detailed images of key protein complexes provide new insights into bacterial photosynthesis
Researchers at the University of Liverpool and collaborators have arrived at a new understanding of bacterial photosynthesis. Using novel techniques, investigators have unveiled intricate detailed images of the key photosynthetic protein complexes of.....»»
Physics team uncovers a quantum Mpemba effect with a host of "cool" implications
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle's observations two millennia ago and modern-day understanding, while opening the door to a whole host of "cool"—and "cooling"—.....»»
Research team develops metallodrug-antibiotic combination strategy to combat superbugs
Antimicrobial resistance (AMR) bacterial infections have become a serious problem threatening human health worldwide. The overuse of antibiotics has promoted drug-resistant mutations in bacteria, causing almost all clinically used antibiotics to deve.....»»
