Bacteria adapt syringe apparatus to changing conditions
Some of the best-known human pathogens—from the plague bacterium Yersinia pestis to the diarrhea pathogen Salmonella—use a tiny hypodermic needle to inject disease-causing proteins into their host's cells, thereby manipulating them. This needle i.....»»
Coral exudates, not algae, linked to bacterial growth that threaten reefs
A study led by the University of Bremen suggests that on algae-dominated coral reefs, it is not the algae but the corals themselves that may contribute to the growth of harmful bacteria. This discovery suggests that a disturbance in the natural compo.....»»
New gold nanorod technology can fry bacteria to sterilize implants
In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold.....»»
Glycans can regulate their own biosynthesis by modifying enzyme activity
Glycans are chains of sugars that attach to cells through proteins or lipids, changing their chemical characteristics. Glycans can be incredibly complex and branched in structure, contributing to the stability of the extracellular domain of cells and.....»»
"Sexual precarity": How insecure work puts migrants at risk of being sexually harassed, assaulted or trafficked
Some of the ways migrants are exploited in the workforce get a lot of public attention. We hear tragic stories about wage theft, forced unpaid overtime, unsafe work conditions or discrimination. And we are likely to hear more such grim stories reveal.....»»
Apple is turning The Oregon Trail into a movie
The film will be a comedy, not a serious historical drama. Apple will adapt the classic educational game The Oregon Trail into a big-budget movie, according to The Hollywood Repor.....»»
Invasive plants drive homogenization of soil microbial communities across US, new study finds
Invasive plants are doing more than just taking over landscapes—they're also changing the soil beneath them. A new study co-authored by Matthew McCary, assistant professor of biosciences at Rice University, reveals that these species are reshaping.....»»
New class of encrypted peptides exhibits significant antimicrobial properties
In a significant advance against the growing threat of antibiotic-resistant bacteria, researchers have identified a novel class of antimicrobial agents known as encrypted peptides, which may expand the immune system's arsenal of tools to fight infect.....»»

CRISPR-Cas10 can flood virally infected bacteria with toxic molecules, researchers discover
CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision......»»
Unique multidomain enzymes from bacteria identified
Pharmaceutical scientists from the National University of Singapore (NUS) have identified and characterized a unique multidomain enzyme capable of catalyzing two distinct types of reactions, both vital for making drug molecules......»»
Adversarial groups adapt to exploit systems in new ways
In this Help Net Security video, Jake King, Head of Threat & Security Intelligence at Elastic, discusses the key findings from the 2024 Elastic Global Threat Report. Adversaries are utilizing off-the-shelf tools Offensive security tools (OSTs), inclu.....»»
Research on how gut bacteria breaks down dietary fiber could lead to helpful new probiotics
There are trillions of bacteria in the human gut microbiome. When we eat fruits and vegetables, some of these bacteria break down the dietary fiber and provide us with metabolites, small molecules our body can use for energy or cell repair......»»
Natural compound found in flowers blocks activity of an enzyme involved in multiple sclerosis and cancer
Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclero.....»»
Life can maintain a habitable environment in hostile conditions, research suggests
Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It's like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive to life? Would it still exi.....»»
iOS 18.2 lets third-party web browsers add web apps with custom engine in the EU
Apple last year introduced the ability for third-party web browsers to add web apps to the iOS Home Screen, a feature that was previously exclusive to Safari. However, these web apps still depend on Apple’s WebKit. But Apple is changing that with i.....»»
New technology illustrates bacterial "hibernation states"
Like hibernating bears, certain bacterial cells have the ability to shift into a "low-power" metabolic state in which they can stably survive without growing. This state is often seen in the context of antibiotic-resistant infections as bacteria form.....»»
How pollsters have adapted to changing technology and voters who don"t answer the phone
As the U.S. presidential election approaches, news reports and social media feeds are increasingly filled with data from public opinion polls. How do pollsters know which candidate is ahead in what swing state or with which key demographic group? Or.....»»

Researcher finds special proteins are key when antibiotic resistance spreads
Antibiotic resistance is a growing public health problem globally. The problem is exacerbated by the fact that some bacteria that have become resistant to antibiotics have the ability to spread that resistance to other bacteria via secretion systems......»»
