Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»

One of Australia's most endangered parrots is facing a new threat after being found to carry a destructive pathogen normally associated with several varieties of crops......»»
High-energy-density chemical fuel powers bug-sized robots to leap, lift and race
Cornell researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors......»»
Two ways to optimize Apple’s redesigned iMessage apps experience in iOS 17
One of the more noticeable design changes in iOS 17 is in the Messages app. Apple has revamped the interface and moved access to iMessage apps and shortcuts to a new pop-up menu. Here’s a closer look at these changes, with a trick to get one-tap ac.....»»
New recipes for origin of life may point way to distant, inhabited planets
Life on a faraway planet—if it's out there—might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. A team led by scientists at the University of Wisc.....»»
Molecular properties are only weakly correlated, study finds
The number of molecules thought to exist is unfathomably large—somewhere between 1050 and 1060 (for comparison, there are only 1022 to 1024 stars in the observable universe). The chemical and pharmaceutical sciences have sought a comprehensive unde.....»»
Team develops novel ligands for transition-metal catalysis of photoreactions
Transition metals form catalytic complexes that can speed up various chemical processes, especially in the production of pharmaceuticals as well as various pigments, dyes, and laboratory reagents like sulfuric acid. The use of light emitting diodes (.....»»
The iPhone"s new Action Button is more than a one-trick pony
The new iPhone 15 Pro lineup offers a lot to get excited about: They're slimmer and thinner, the new cameras are professional-grade and the switch to USB-C charging will make your life easier. But one new feature easily stands out as the most fun: Th.....»»

Researchers study the formation of cardenolides in plants
Scientists at the Max Planck Institute for Chemical Ecology in Jena are investigating the previously largely unknown biosynthetic pathway that leads to the formation of cardenolides in plants......»»
Possible hints of life found on distant planet. How excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely i.....»»
Supermassive black holes affect the chemical composition of their host galaxies, research shows
New research shows that the supermassive black hole at the center of a galaxy can have a direct impact on the chemical distribution of the host galaxy. This provides another piece of the puzzle for understanding how galaxies evolve......»»
Scientists probe the source of key hydrocarbons on Earth—and in space
Polycyclic aromatic hydrocarbons (PAHs) are a type of organic molecule that carry fused rings made of the chemical benzene. Scientists believe that PAHs are responsible for chemical processes that eventually lead to soot and other carbonaceous nanopa.....»»
Scientists uncover surprising twist in the ways bacteria spread antibiotic-resistant genes
Scientists have found a counterintuitive wrinkle in the way bacteria spread antibiotic-resistant genes through small circular pieces of DNA called plasmids......»»
Team develops technique for building DNA-based programmable gate arrays
A team of chemists and chemical engineers at Shanghai Jiao Tong University, working with a colleague from the Chinese Academy of Sciences, both in China, has built a DNA-based programmable gate array for use in general-purpose DNA computing. In their.....»»
Dual Trojan Horse strategy to combat superbugs
In the relentless battle against antibiotic-resistant superbugs, science continues to unveil ingenious strategies to address their vulnerability. Like other bacteria, superbugs have a unique weakness—their dependence on iron for growth and survival.....»»
A novel method to obtain acetone in slow-cost, simple manner
Acetone is an essential chemical industry input and is used in the manufacturing of a wide array of products, such as adhesives, antibiotics, electronic components, solvents and removers, inks and vitamins, among others. Its production is complex an.....»»
Scientists create process to upcycle plastics into energy-storage liquids using light-emitting diodes
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a process that can upcycle most plastics into chemical ingredients useful for energy storage, using light-emitting diodes (LEDs) and a commercially available cat.....»»
Using lasers to choose and export single-cell cultures: An efficient upgrade to static droplet array tool
Static droplet array (SDA) is a necessary and integral tool when it comes to high-capacity screening tests, or assays, for identifying and targeting specific cells or analytes (substances whose chemical composition is the target of identification). H.....»»
Requests via Facebook Messenger lead to hijacked business accounts
Hijackers of Facebook business accounts are relying on fake business inquiries and threats of page/account suspension to trick targets into downloading password-stealing malware. Examples of phishing messages. (Source: Guardio Labs) The campaign Hija.....»»
