New molecule found in chestnut leaves disarms dangerous staph bacteria
Scientists isolated a molecule, extracted from the leaves of the European chestnut tree, with the power to neutralize dangerous, drug-resistant staph bacteria......»»
Non-culturable Legionella identified with sequencing
Legionnaires' disease (LD), a rare and severe type of pneumonia, is a respiratory infection caused by species of Legionella bacteria. One of the most accurate ways to diagnose LD is to perform culture on samples from a patient's lower respiratory tra.....»»
Lifesaving gene therapy for kids is world’s priciest drug at $4.25M
It's unclear if government and private insurance plans can cover the costs. Enlarge / A mother with her twin 6-year-old boys who have metachromatic leukodystrophy, a genetic disease that leaves them unable to move. Photo taken on.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting fro.....»»
Darkness rises in an age of light in first trailer for Star Wars: The Acolyte
"This isn't about good or bad. This is about power and who is allowed to use it." Amandla Stenberg stars as a former padawan turned dangerous warrior in Star Wars: The Acolyte. A long time ago, in a galaxy far, far away, the Galacti.....»»
OpenAI’s latest Sora video shows an elephant made of leaves
Text-to-video technology powered by AI is making rapid improvements — just take a look at the latest footage created by OpenAI's incredible Sora tool......»»
Genes identified that allow bacteria to thrive despite toxic heavy metal in soil
Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to not only thrive in otherwise toxic soils but help plants grow there as well......»»
Advancements in greenhouse spike detection with deep learning for enhanced phenotypic trait analysis
Accurate extraction of phenotypic traits from image data is essential for cereal crop research, but spike detection in greenhouses is challenging due to the environmental and physical similarities between spikes and leaves. Recent efforts include inc.....»»
Brewing kombucha in silicone bags makes for less alcohol, faster process
Using glucose instead of sucrose also results in less alcohol and less sour vinegar taste Enlarge / Brewing kombucha tea. Note the trademark gel-like layer of SCOBY (symbiotic culture of bacteria and yeast). (credit: Olga Pankova.....»»
New discovery highlights a potential stepping stone toward antibiotic resistance
A new study shows how heteroresistance, a transient resistance common in many bacteria, can act as a precursor to the development of antibiotic resistance. According to researchers at Uppsala University, this is the first time this link has been demo.....»»
Projection mapping leaves the darkness behind
Images projected onto objects in the real world create impressive displays that educate and entertain. However, current projection mapping systems all have one common limitation: they only work well in the dark. In a study recently published in IEEE.....»»
Methane: a powerful gas heating the planet
Climate talks often revolve around reducing the most dangerous greenhouse gas CO2......»»
Better kombucha brewing through chemistry
Kombucha is a fermented tea known for its health benefits and tangy kick. But brewers can find it challenging to keep kombucha's alcohol levels low because the bacteria and yeast used in the fermentation process vary from batch to batch......»»
Not just a lodger: Novel host-guest assembly provides enhanced reactivity
By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical str.....»»
Urban humans have lost much of their ability to digest plants
Rural populations still have lots of the gut bacteria that break down cellulose. Enlarge (credit: Nathan Devery) Cellulose is the primary component of the cell walls of plants, making it the most common polymer on Earth......»»
Forest and stream habitats keep energy exchanges in balance, global team finds
Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic.....»»
Alzheimer"s drug fermented with help from AI and bacteria moves closer to reality
Galantamine is a common medication used by people with Alzheimer's disease and other forms of dementia around the world to treat their symptoms. Unfortunately, synthesizing the active compounds in a lab at the scale needed isn't commercially viable......»»
Climate Change Is Bad for Your Health, Wherever You Are
Rising temperatures are a threat regardless of where you live on the planet—they’re just dangerous in different ways......»»
Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»
Sugar-coated gold nanoparticles can quickly eliminate bacterial infections, no antibiotics required
If left to their own devices, bacteria on our teeth or wounded skin can encase themselves in a slimy scaffolding, turning into what is called biofilm. These bacteria wreak havoc on our tissue and, being shielded from antibiotic medication by the slim.....»»
Exploring the transferability of extracytoplasmic function switches across bacterial species
Extracytoplasmic function sigma factors (ECFs) have been successfully used for constructing predictable artificial gene circuits in bacteria like Escherichia coli, but their transferability between species within the same phylum remained unknown......»»
