Examining electron transport shuttles in microorganisms
Every living thing requires energy. This is also true of microorganisms. Energy is frequently generated in the cells by respiration, that is, by the combustion of organic compounds—in other words, food. During this process, electrons are released,.....»»
Atmospheric microplastic transport predominantly derived from oceans, study finds
Microplastics in our natural environments are of increasing concern as these tiny particles (.....»»
Scientists develop model to predict and simulate microplastic transport in South Australian waters
Australia has a big problem with plastic waste, with millions of tons of household and industrial plastics breaking down in landfill, rivers and the sea every year......»»
WHO says flu vaccines should ditch strain that vanished during COVID
Influenza viruses in the B/Yamagata lineage have not been seen since March 2020. Enlarge / Influenza virus. Image produced from an image taken with transmission electron microscopy. Viral diameter ranges from around 80 to 120 nm......»»
Examining ethical considerations for human remains
In 2022, the Penn Museum announced that it would rebury the skulls of dozens of Black Philadelphian individuals whose remains were unethically obtained in the mid-1800s. Some in the community of the individuals' descendants, who felt they were not co.....»»
Q&A: Indigenous community-first approach to more ethical microbiome research
Every person hosts trillions of microorganisms, like bacteria and viruses, on their skin and in organs including those that make up the digestive tract, like their mouth, that collectively make up their microbiome. Microbiome research can lead to med.....»»
Your microbes live on after you die—a microbiologist explains how your necrobiome recycles your body
Each human body contains a complex community of trillions of microorganisms that are important for your health while you're alive. These microbial symbionts help you digest food, produce essential vitamins, protect you from infection and serve many o.....»»
Intense lasers shine new light on the electron dynamics of liquids
An international team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and ETH Zurich has now demonstrated that it is possible to probe electron dynamics in liquids using intense laser fields and.....»»
Recent manipulations of excitons in moiré superlattices
Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, they stay bound together,.....»»
Examining the genesis of CRISPR"s molecular scissors
Genome engineering may be the future of medicine, but it relies on evolutionary advances made billions of years ago in primordial bacteria, the original masters of gene editing......»»
Team develops key improvement to cryo-electron microscopy
The scientists who received the 2017 Nobel Prize in chemistry were honored for their development of a technique called cryo-electron microscopy, or cryo-EM. The technology was revolutionary because it enabled scientists to see the atomic structure of.....»»
Examining how weather patterns will change in the future
In a warming Pacific Northwest, summers are getting hotter and winters less cold, but the atmospheric patterns that influence the weather aren't necessarily expected to become stronger or more frequent by the end of the century, according to a new Po.....»»
New study definitively confirms gulf stream weakening
The Gulf Stream transport of water through the Florida Straits has slowed by 4% over the past four decades, with 99% certainty that this weakening is more than expected from random chance, according to a new study......»»
Examining how much wildfire smoke influences air quality trends
Stanford research reveals the rapidly growing influence of wildfire smoke on air quality trends across most of the United States. Wildfire smoke in recent years has slowed or reversed progress toward cleaner air in 35 states, erasing a quarter of gai.....»»
NASA"s moonbound Artemis astronauts take new ride to launch pad in practice run
The four astronauts headed to the moon next year on the Artemis II mission suited up and took a practice run to the launch pad in the new crew transport vehicles at Kennedy Space Center on Wednesday......»»
Failure strikes Rocket Lab after launch from New Zealand
The Electron rocket now has a 90 percent success rate. Enlarge / Rocket Lab's Electron launch vehicle lifts off Tuesday from New Zealand on an ill-fated mission. (credit: Rocket Lab) Rocket Lab's string of 20 consecutive.....»»
Novel approach to engineered cells may enable molecular medical imaging
A tiny molecular structure that looks like a bubble may be able to significantly improve medical imaging, according to a Penn State research team. Called gas vesicles (GVs), these structures are naturally produced by certain microorganisms and are re.....»»
Visualizing electron flow motivates new nanoscale devices inspired by airplane wings
A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed......»»
Experiment demonstrates how worm hosts and associated microbiome jointly contribute to environmental adaptation
A Kiel research team has used a near-natural compost mesocosm experiment to demonstrate that worm hosts and the associated microorganisms jointly mediate adaptation to a novel environment.....»»
SLAC fires up the world"s most powerful X-ray laser: LCLS-II ushers in a new era of science
The newly upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL) at the Department of Energy's SLAC National Accelerator Laboratory successfully produced its first X-rays, and researchers around the world are already lined up to.....»»
Single cell protein: An alternative eco-friendly protein source derived from microorganisms
Researchers and businesses are increasingly drawn to alternative protein sources as they grapple with the challenge of meeting the growing global demand for protein. Among the unconventional sources, microorganisms stand out for their remarkable prot.....»»
