Ultrashort-pulse lasers kill bacterial superbugs, spores
Life-threatening bacteria are becoming ever more resistant to antibiotics, making the search for alternatives to antibiotics an increasingly urgent challenge. For certain applications, one alternative may be a special type of laser......»»
Study finds wild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations. A team led by Coleen Murphy at Princeton University report t.....»»
Attaching seaweed spores to used scallop shells could restore UK"s coastal kelp forests
Kelp spores are being seeded and grown on small rocks and scallop shells—a seafood waste product—in efforts to regenerate the UK's coastal kelp forests......»»
Unlocking visible femtosecond fiber oscillators: An advance in laser science
The emergence of ultrafast laser pulse generation, marking a significant milestone in laser science, has triggered incredible progress across a wide array of disciplines, encompassing industrial applications, energy technologies, life sciences, and b.....»»
Sniffing out bacteria: Team develops a novel approach for rapid bacterial species identification
Do you ever wonder how researchers identify bacterial infections? Traditionally, they collect samples from the infected site, grow the bacteria in a lab, and analyze them using a method called MALDI-ToF-MS. Although accurate, this method is time-cons.....»»
Micro-Lisa: Making a mark with novel nano-scale laser writing
High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components......»»
Biologists determine bacteria sense damage to relatives
Carnegie Mellon University biologists have discovered that Vibrio cholerae, the bacteria behind the cholera disease, can sense when its relatives die. Bacterial cell death is often accompanied by lysis, where the cell explodes, releasing internal cel.....»»
Using mode-locked lasers to realize and study non-Hermitian topological physics
Mode-locked lasers are advanced lasers that produce very short pulses of light, with durations ranging from femtoseconds to picoseconds. These lasers are widely used to study ultrafast and nonlinear optical phenomena, but they have also proved useful.....»»
Ultrafast plasmonics for all-optical switching and pulsed lasers
Plasmonics is playing a crucial role in advancing nanophotonics, as plasmonic structures exhibit a wide range of physical characteristics that are benefited by localized and intensified light-matter interactions. These properties are exploited in num.....»»
Rescuers race to find trapped people as Brazil storms kill at least 20
Rescuers in boats and aircraft raced against the clock Sunday to help isolated people in Brazil's mountainous southeast after storms and heavy rains killed at least 20 people......»»

New tuberculosis study offers a novel paradigm for understanding bacterial transcription
The bacterium behind tuberculosis is a wily foe, adept at bobbing and weaving around the immune system and antibiotics alike. Mycobacterium tuberculosis (Mtb) has been notoriously difficult to eradicate, often dormant in the body for years only to re.....»»
Tracking and tracing members of the plant microbiome with DNA barcodes
A research team led by Paul Schulze-Lefert from the Max Planck Institute for Plant Breeding Research in Cologne, Germany, developed a modular toolkit for tracking bacterial strains colonizing plant tissue in competition with other microbiome members......»»
Animal hair structure changes from summer to winter to fend off freezing weather, researchers show
Unique adaptations allow wild animals to survive temperature extremes that would quickly kill an unprotected human. For example, certain animals can withstand bitterly cold weather, thanks to the insulating properties of the hollow hairs that make up.....»»
Rumors of an affordable Samsung Galaxy Z Fold 6 could kill off Ultra hopes
Rumors point to Samsung developing a more affordable Galaxy Z Fold but this likely means we won’t see a premium Galaxy Z Fold 6 Ultra this year......»»
Nanozyme-enabled nanodecoys: A new strategy for fighting urinary tract infections
Urinary tract infections (UTIs), affecting millions worldwide, are predominantly caused by uropathogenic Escherichia coli (UPEC). These infections are characterized by bacterial adhesion and colonization in the urinary tract, evading host immune resp.....»»
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.....»»
Deciphering how viruses choose to turn nasty or not to their bacterial host
Researchers from the Shmunis School of Biomedicine and Cancer Research at Tel Aviv University have deciphered a novel complex decision-making process that helps viruses choose to turn nasty or stay friendly to their bacterial host. In a new paper, th.....»»
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......»»
Apple Watch pulse oximeter ban detailed in published documents
New information about the Apple Watch ban, like how permanent the solution is and when it can be lifted, has been detailed in the now published Customs order.Apple Watch Series 9 can't be sold with the blood pulse oximeter enabledWhen an import ban a.....»»
Higher bacterial counts detected in single-serving milks
