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......»»
Dig safely when building sandcastles—collapsing sand holes can cause suffocation and even death
While millions of Americans vacation on beaches every year to seek out sun, sand and the sea, many might not realize how dangerous digging holes in the sand can be. In February 2024, a 7-year-old girl died after an approximately 5-foot (1.5-meter) ho.....»»
The geometry of life: Physicists determine what controls biofilm growth
From plaque sticking to teeth to scum on a pond, biofilms can be found nearly everywhere. These colonies of bacteria grow on implanted medical devices, our skin, contact lenses, and in our guts and lungs. They can be found in sewers and drainage syst.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Certain bacteria or fungi could combat a plant pathogen that attacks common vetch
Anthracnose, a severe disease caused by the Colletotrichum spinaciae plant pathogen, often occurs in common vetch, a widely grown legume. Chemicals are not recommended for disease management because the plants are used as livestock feed. A new study.....»»
Careful, that jQuery package could be loaded with Trojans
Researchers found dozens of fake jQuery packages, carrying dangerous malware......»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
Deep learning model enhances maize phenotype detection and crop management
A research team has developed the Point-Line Net, a deep learning method based on the Mask R-CNN framework, to automatically recognize maize field images and determine the number and growth trajectory of leaves and stalks. The model achieved an objec.....»»
New microbe-central model predicts global grassland soil pH under climate change
In a study published in One Earth on July 5, a research team led by Prof. Deng Ye from the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences proposed the core-bacteria-forecast model (CoBacFM), which links the changes.....»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»

Mexico prepares for Hurricane Beryl landfall
Tourist resorts in Mexico steeled Friday for a hit from Hurricane Beryl, which is expected to bring ferocious winds and a dangerous storm surge to the Yucatan Peninsula after slamming Jamaica and the Cayman Islands......»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
Study reveals rapid evolution and global spread of Pseudomonas aeruginosa
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven b.....»»
Caterpillars pass down food preferences to offspring through blood
Many caterpillars are known for their specific food preferences, which they bring with them when they morph into butterflies. For instance, the monarch butterfly only feeds on milkweed plants, while the Lime butterfly feeds on lime leaves. Despite de.....»»
The influence of peptoid sequence on the mechanisms and kinetics of 2D assembly
Two-dimensional (2D) materials have unique physical and chemical properties and potential for a wide variety of applications. Peptoids, a type of molecule, compose a class of sequence-defined polymers that mimic biological compounds and can self-asse.....»»
Thousands told to flee raging California wildfire
Thousands of people have been ordered to evacuate as a wildfire rages out of control in northern California, with a swathe of the United States in the grip of a "record-breaking and dangerous" heat wave that was complicating firefighting efforts......»»
New organic molecule shatters phosphorescence efficiency records and paves way for rare metal-free applications
A research team led by Osaka University discovered that the new organic molecule thienyl diketone shows high-efficiency phosphorescence. It achieved phosphorescence that is more than ten times faster than traditional materials, allowing the team to e.....»»
