A robust self-healing polymer made from a common chemical
Material scientists at RIKEN have created a self-healing polymer by using an off-the-shelf compound for the first time. The strategy they used is promising for improving the durability and minimizing the environmental impact of various commercial pol.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
CUPS vulnerabilities affecting Linux, Unix systems can lead to RCE
After much hyping and following prematurely leaked information by a third party, security researcher Simone Margaritelli has released details about four zero-day vulnerabilities in the Common UNIX Printing System (CUPS) that can be abused by remote,.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Affordable iron catalysts offer a sustainable route to prized Z-alkenes
Chemists from the National University of Singapore (NUS) have developed an iron-catalyzed method that overcomes a significant challenge in the sustainable synthesis of trisubstituted Z-alkenes by inserting two alkyl chemical groups into a type of com.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Lignin-based sunscreen offers natural and high-performance UV protection
In a significant breakthrough for the cosmetics industry, researchers have developed a new type of sunscreen using lignin, a naturally abundant polymer, and titanium dioxide (TiO2). The study, led by Yarong Li and Zhiguang Tang, was published in the.....»»
Transforming caragana waste into nutritious ruminant feed
In an advance for agricultural waste management, scientists from the Chinese Academy of Sciences have devised a method to convert Caragana korshinskii Kom. waste, a common forestry byproduct in China, into a potential ruminant feed. The research, pub.....»»
How to save a sinking city
What do Venice, Jakarta, Manilla and Bangkok have in common? They are or were sinking cities. Wageningen researcher Philip Minderhoud studies the causes of subsidence in these cities. Groundwater extraction plays an important part in all cases. The g.....»»
"Tamed" molecules for more sustainable catalysts: Chemists succeed in synthesizing a spectacular gallium compound
Catalysts play an important role in the manufacture of many products that we encounter in everyday life—for example in cars for exhaust gas purification or in the chemical industry in the production of fertilizers. Catalysts ensure that these react.....»»
Biologists sequence proteins by pulling them through nanopores
A team of chemical biologists at the University of Washington, working with colleagues at Oxford Nanopore Technologies, has developed a protein sequencing process that involves pulling proteins through nanopores in a lipid membrane. Their paper is pu.....»»

From contraception access to safe abortion, there is growing awareness about reproductive health and rights......»»
Study reveals mallards" flight responses ineffective in preventing vehicle collisions
An article published in PeerJ Life & Environment has uncovered insights into how mallards (Anas platyrhynchos) respond to approaching vehicles, revealing that these common waterbirds are poorly equipped to avoid collisions, particularly at high speed.....»»
Ingredients used in chewing gum help tilapia survive cold climates
Two common ingredients in ordinary chewing gum—Arabic gum and lecithin—have been found to help improve the overall health of tilapia, helping these fish survive better even in cold climates. This discovery paves the way for raising tilapia for fo.....»»
Shrinking augmented reality displays into eyeglasses to expand their use
Augmented reality (AR) takes digital images and superimposes them onto real-world views. But AR is more than a new way to play video games; it could transform surgery and self-driving cars. To make the technology easier to integrate into common perso.....»»
Morphology study paves the way for spider fang-inspired cutting tools
When we think of spiders, the first thing that comes to mind is their ability to weave intricate and robust webs. But their ability to cut their own silk—the toughest natural material—and strong or tough synthetic fibers such as carbon or Kevlar,.....»»
Research abounds at the International Space Station
At the International Space station, researchers are making strides in everything from Earth science to chemical properties. Here's what they're up to and why it matters......»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
A secret recipe for colorful and versatile animal crystals
What do fish, chameleons, crabs and Walter White, the chemistry teacher from "Breaking Bad," all have in common? The answer is that they all know how to make crystals. But, unlike the incorrigible White, who manufactured mind-altering methamphetamine.....»»
Study finds family members are most common perpetrators of infant and child homicides in the US
Homicide is a leading cause of death among people 19 and younger in the United States, and firearms are used in a large proportion of these crimes. Although the homicide rate for this population declined in the 1990s and 2000s, it has increased every.....»»
