Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
Team reports on relationship between contents of diosgenin and brassinosteroids in Dioscorea zingiberensis
Diosgenin, a secondary metabolite isolated from the Dioscorea spp. plant family, is an irreplaceable and ideal starting material for the synthesis of steroid hormone drugs. Dioscorea zingiberensis is the world's most desirable and important plant sou.....»»
A new method for enzymatic synthesis of potential RNA therapeutics
A team of researchers at IOCB Prague led by Prof. Michal Hocek has developed a novel method for preparing ribonucleic acid (RNA) containing modified bases. Innovative use of engineered DNA polymerases, enzymes commonly used for the synthesis of DNA,.....»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
Chemists introduce new copper-catalyzed C-H activation strategy
Inspired by what human liver enzymes can do, Scripps Research chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widel.....»»
The beginnings of modern science shaped how philosophers saw alien life—and how we understand it today
Speculation about extraterrestrials is not all that new. There was a vibrant debate in 17th-century Europe about the existence of life on other planets......»»
New research could enable more—and more efficient—synthesis of metastable materials
Ion exchange is a powerful technique for converting one material to another when synthesizing new products. In this process, scientists know what reactants lead to what products, but how the process works—the exact pathway of how one material can b.....»»
New benzofuran synthesis method enables complex molecule creation
In the field of organic chemistry, scientists are always looking out for new types of reactions to unlock synthesis routes for challenging compounds. Most of the progress that we have witnessed in pharmaceutics and agrochemicals over the past few dec.....»»
L-cyclodextrins synthesized in the lab for the first time
A team of chemists at Northwestern University has successfully synthesized three L-cyclodextrins in the lab for the first time. In their study, published in the journal Nature Synthesis, the group used a one-pot strategy to achieve the feat......»»
Palladium nanocluster catalyst supports highly efficient and regioselective hydrogenation of epoxides
Alcohols are widely applied in life sciences and the chemical industry. Selective hydrogenation of epoxides using hydrogen molecules as a reductant is considered to be one of the most facile and atom-economical strategies for alcohol synthesis. Howev.....»»

On-surface synthesis of carbyne: An sp-hybridized linear carbon allotrope
In a study led by Prof. Wei Xu (Interdisciplinary Materials Research Center, School of Materials Science and Engineering, Tongji University) and published in the journal National Science Review, a research team achieved the successful synthesis of a.....»»
92,000+ internet-facing D-Link NAS devices accessible via “backdoor” account (CVE-2024-3273)
A vulnerability (CVE-2024-3273) in four old D-Link NAS models could be exploited to compromise internet-facing devices, a threat researcher has found. The existence of the flaw was confirmed by D-Link last week, and an exploit for opening an interact.....»»
Study confirms A. yasumatsui as sole biotic threat to Micronesian cycad
A new study has confirmed that the invasive A. yasumatsui, known as Cycad Aulacaspis Scale (CAS), stands alone as the greatest threat to the existence of the Cycas micronesica species. The endemic cycad species to Micronesia has thrived in the region.....»»
New synthesis platform allows for rapid cancer drug synthesis and testing
Imperial College London researchers have developed a new platform for the synthesis, analysis and testing of new compounds which may one day treat cancer. The findings are published in the journal Angewandte Chemie International Edition......»»
Stellar murder: When stars destroy and eat their own planets
Our sun is both our best friend and our worst enemy. On the one hand, we owe our very existence to our star. Earth and the other planets in the solar system formed out of the same cloud of gas and dust as the sun......»»
OpenAI holds back wide release of voice-cloning tech due to misuse concerns
