Iridium-catalyzed Z-retentive asymmetric allylic substitution reactions
In synthetic organic chemistry, Z-olefins are a challenging synthetic target to produce in the lab due to their relative thermodynamic instability. The Z-olefins form an unsaturated compound with a CnH2n formula that can be readily isomerized. Analog.....»»
The fountain of life: Water droplets hold the secret ingredient for building life
Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water—something that has puzzled scientists for decades......»»
Delayed slow ocean response to carbon dioxide removal causes asymmetric tropical rainfall change
Using fossil fuels causes large amounts of carbon dioxide (CO2) to be emitted, which is one of the major greenhouse gases responsible for global warming. The climate changes under increasing CO2 radiative forcing (called "CO2 ramp-up") have been wide.....»»
Hackmanite also changes color upon exposure to nuclear radiation: Memory trace enables new applications
Researchers at the University of Turku, Finland, have long studied the color-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group is studying the reactions of synthetic hackmanite to n.....»»
Apple is taking credit for Google adding iMessage reactions on Android
Before Google’s “Get The Message” campaign in August, Android’s Messages app was updated with iMessage reactions at the start of this year. In a very weird turn of events, Apple appears to be taking credit for Google adding iMessage reaction.....»»
The process of waves carrying plasma heat is observed for the first time
In fusion power generation, it is essential that the high-energy particles generated by a fusion reaction in hot plasma heat it to sustain further fusion reactions. The key to this self-heating of the plasma is whether it can be heated by waves creat.....»»
Better understanding of cellular metabolism with the help of AI
Metabolism is essential to all living organisms, and modeling the chemical reactions that sustain life is no easy task. Now, EPFL scientists have released REKINDLE, a deep-learning process that is paving the way for more efficient and accurate modeli.....»»
Physicists make molecular vibrations more detectable
In molecules, the atoms vibrate with characteristic patterns and frequencies. Vibrations are therefore an important tool for studying molecules and molecular processes such as chemical reactions. Although scanning tunneling microscopes can be used to.....»»

MSI Express (Unilever) issued a recall for about 16,498 pounds of Knorr chicken and rice soup mix products that contain an undeclared allergen. The allergen in question is milk, an ingredient that can cause mild or even severe reactions in some peopl.....»»
WhatsApp for iOS plans to bring Stories-like feature to the chat list
WhatsApp for iOS is always working on a handful of new features. Over this year, the app introduced Reactions, the ability to migrate the chat history from iOS to Android (and vice versa), and many more other features. But now, Mark Zuckerberg’s m.....»»
Novel smart material enables high-performance and reliable light control of droplets
The ability to manipulate droplets plays a vital role in fundamental research and practical applications from chemical reactions to bio-analysis. Light control of droplets enables remote and contactless control with remarkable spatial and temporal ac.....»»
Scientists realize nickel-catalyzed asymmetric heteroarylative cyclotelomerization of isoprene
Isoprene is used as a precursor to produce terpenes and terpenoids. However, the direct catalytic conversion of isoprene to terpenoids is challenging......»»
GOP "message laundering" turns violent, extremist reactions into acceptable political talking points
After the FBI completed a lawful search of former president Donald Trump's Mar-a-Lago estate on Aug. 8, 2022, conservative politicians responded with one of three strategies: silence, circumspection and attack......»»
Building the best zeolite
If science and nature were to have a baby, it would surely be the zeolite. This special rock, with its porous structure that traps water inside, also traps atoms and molecules that can cause chemical reactions. That's why zeolites are important as ca.....»»
