    Life On Earth Began With A Strange Change In Chemistry, New Theory Proposes

    via Newsweek : Scientists believe that life on Earth first formed about 3.8 billion years ago with simple, single-celled organisms. But how did the complex processes necessary for life begin in the first place? Scientists from NASA and the National Science Foundation have found a possible explanation of how the citric acid cycle, or the Krebs cycle, could have formed in early Earth. Every aerobic organism on Earth today needs the Krebs cycle, which uses a […]

  • The Chemical Reaction That Cleans Everything

    The Chemical Reaction That Cleans Everything

    via The New York Times : Q. What exactly does bleach do? If I soak a cracked dish, the stains seem to be gone — but are they really? A. The active ingredient of bleach is sodium hypochlorite, which is made up of three common elements, sodium, oxygen and chlorine, said May Nyman, professor of chemistry at Oregon State University. The rest of what is in the bleach bottle is mostly water. “Of those three […]

    Breaking The Chain—Catalyzing A Green Future For Chemistry

    via Phys.org : Osaka University researchers create catalyst for refining chemicals in plant waste, allowing a green way to produce valuable raw materials. The fight against climate change is a call-to-arms for industry. We currently rely on fossil fuels, a major source of the greenhouse gas CO2, not only for energy but also to create chemicals for manufacturing. To ween our economies off this dependency, we must find a new source of “green” raw materials so […]

  • The Intricate Dance of Chemical Reactions: Chemical Kinetics to Chemical Dynamics

    The Intricate Dance of Chemical Reactions: Chemical Kinetics to Chemical Dynamics

    via Decoded Science : Some chemical reactions seem to occur within a blink of an eye, while others take place over long time frames. The rate (speed) at which a reaction proceeds is fundamental to all chemistry, but particularly in the areas of kinetics and chemical dynamics. As sub-disciplines of physical chemistry, kinetics and chemical dynamics are concerned with the measurement of reaction rates, and most notably, for controlling the end products of a reaction. The […]

  • Seeing the Invisible World with the 2017 Nobel Prize in Chemistry

    Seeing the Invisible World with the 2017 Nobel Prize in Chemistry

    via The New Yorker : Chemistry sits halfway between physics and biology; it’s the middle child in the scientific family, as dependable as it is overshadowed. On Monday, the Nobel Prize in Physiology or Medicine was awarded to three researchers who helped elucidate the mechanics of circadian rhythms, the gene-based clocks within our cells; on Tuesday, the physics prize honored the discovery, finally confirmed in 2016, of gravitational waves. By the time chemistry rolled around, […]

  • The science behind fireworks: ‘Chemistry in action’

    The science behind fireworks: ‘Chemistry in action’

    Via AccuWeather : Every Independence Day, millions of Americans gather to experience the loud cracks, booms and incandescent bursts of celebratory fireworks displays. The mechanics of our patriotic pyrotechnics come entirely from chemistry, the driving force behind the motion, heat, light, smoke and sound of these brilliant, captivating displays. “Everything you see in a fireworks display is chemistry in action,” Washington College adjunct chemistry professor John Conkling explained in an educational video. While the chemistry of […]

  • Flow Chemistry Reaches Manufacturing Milestone

    Flow Chemistry Reaches Manufacturing Milestone

    via c&en : Lilly chemists make chemotherapy drug candidate in a multistep continuous flow process using current Good Manufacturing Practices. Although continuous flow chemistry—wherein molecules are made in a continuous process rather than in batches—has gained ground in academic labs, its adoption by industry and contract manufacturing labs has been comparatively slow. Now, chemists at Eli Lilly & Co. report a continuous manufacturing process for the chemotherapy drug candidate prexasertib monolactate monohydrate. Notably, the synthesis uses […]

  • Genetic engineering through click chemistry

    Genetic engineering through click chemistry

    Via C&EN : Gene therapy and a range of biological research rely on the efficient delivery of nucleic acids into cells through the process known as transfection. Most widely-used transfection approaches for mammalian cells rely on electrostatic forces, usually taking advantage of cationic reagents to bind to negatively-charged nucleic acids and form strong ionic complexes. Cells then grab these complexes and internalize them through a process called endocytosis. However, the concentration of positive charge in the […]

  • The science of songs: how does music affect your body chemistry?

    The science of songs: how does music affect your body chemistry?

    Via The Guardian : Classical music makes shoppers buy more. Gentle tunes can cure insomnia. How? Writer, composer and science lecturer John Powell explains. Like many music lovers I’ve always had a fascination with the emotional power. How can a combination of sounds make all the hairs on your arms stand on end, or make you cry? I’ve always enjoyed reading newspaper and magazine articles about the psychological effects of music, but apart from the general […]

  • Smart chemistry is everywhere in everyday life

    Smart chemistry is everywhere in everyday life

    Via Albany Business Review : If you’re like many people, when you think of chemistry one of two images pops into your head: visions of the periodic table from your high school chemistry class or images of labs and beakers, microscopes and white coats. It may feel like chemistry is worlds away from your present daily life, but what you may not realize is the significance of chemistry and its impact all around you. Chemistry improves […]
