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.....»»
Snapchat adds editable chats, emoji reactions, new AI features
Today, Snap announced a host of feature updates coming to Snapchat that are sure to make its users happy. The two standout improvements center around messaging: editable messages and emoji reactions. These join a handful of service-wide enhancements.....»»
Too many vehicles, slow reactions and reckless merging: New math model explains how traffic and bacteria move
What do the flow of cars on a highway and the movement of bacteria towards a food source have in common? In both cases, annoying traffic jams can form. Especially for cars, we might want to understand how to avoid them, but perhaps we've never though.....»»
Physicists overcome two key operating hurdles in fusion reactions
A team of physicists from several institutions across the U.S. working with a colleague from China, at the DIII-D National Fusion Facility, in San Diego, California, has devised a way to overcome two key hurdles standing in the way of using fusion as.....»»
Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature.....»»
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.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
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.....»»
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much o.....»»
Novel UV broadband spectrometer improves air pollutant analysis
Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example is the formation of.....»»
New strategy for assessing the applicability of reactions
Chemists often develop and optimize new chemical reactions using so-called model systems, i.e., simple, easily accessible substrates. They then use up to around 100 other substrates as examples to show that the reaction works. This demonstration of v.....»»

Clocks going forward can catch investors napping: How investors" reactions are affected by sleep disruption
Clocks losing an hour in spring significantly affects how investors respond to companies that reveal unexpected levels of earnings, research shows......»»
Chemical reactions can scramble quantum information as well as black holes
If you were to throw a message in a bottle into a black hole, all of the information in it, down to the quantum level, would become completely scrambled. Because in black holes this scrambling happens as quickly and thoroughly as quantum mechanics al.....»»
Operando spectroscopy provides a window on water oxidation
Iridium oxide catalysts are effective for water oxidation making them very attractive for green technologies. A team including researchers from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University has therefore taken the c.....»»
The role of interfacial amino acids in shaping bio-electronic communication between proteins
Proteins are vital for facilitating charge transport (CT) chain reactions, both within individual proteins and between proteins. Understanding CT in proteins is crucial for biological processes and the development of bioelectronic devices. While prev.....»»
Cats with MDR1 mutation at risk of severe reactions to popular medication
More than half a million cats in the United States could be at risk of a severe or even fatal neurological reaction to the active ingredient in some top-selling parasite preventatives for felines......»»
Your emotional reaction to climate change may impact the policies you support, study finds
Emotional reactions to climate change may lead to specific policy preferences, according to a study published in the open-access journal PLOS Climate by Teresa A. Myers of George Mason University and colleagues......»»
