Frozen Fish Embryos Warm Up Better with Nanorods

By Jyoti Madhusoodanan, for C&EN

Zebrafish (Danio rerio) are widely used as a model organism for developmental biology. But after being frozen and thawed, zebrafish embryos rarely survive, meaning that researchers can only do experiments on live ones and can’t store embryos for later experiments or to share with other labs. Now, researchers report that injecting zebrafish embryos with gold […]

Keeping a Close Eye on Lithium Ions

By Katherine Bourzac for C&EN

After a year or so, lithium-ion batteries—used in cell phones, laptops, and electric cars—need more frequent recharging. And on rare occasions, the batteries can fail catastrophically. A new way to directly image lithium ions could help researchers better understand why these problems happen, helping them to improve battery design. Li-ion batteries can catch fire when […]

Cane Toad Microbiome Transforms its Toxins

By Melissae Fellet, for C&EN

Australia’s invasive cane toads are a scourge to native species, poisoning predators with toxic secretions. But now researchers have discovered that bacteria in the glands of adult cane toads transform these toxins into hydroxylated versions found in cane toad eggs and tadpoles. Manipulating this microbe-mediated toxin transformation could offer a new route for controlling the […]

Understanding How Mother-of-Pearl Promotes Bone Growth

By Melissa Pandika

The Mayans used seashells as dental implants, and researchers have shown that small chunks of mother-of-pearl, the iridescent lining of oysters’ and other mollusks’ shells, induce bone formation in both cell culture and animal studies. Why this works, however, has been a mystery. Researchers are now a step closer to the answer. A new work […]

Training of Bomb-Sniffing Dogs Could Improve with New Mass Spectrometry Tool

By Melissa Pandika

Law enforcement has long relied on canines to sniff out dangerous explosives, but large discrepancies exist between individual dogs’ performances that are at least partially attributable to training differences. Now, analytical chemistry may help give the dogs’ powerful sense of smell a keener edge. Researchers have developed a device that could improve dogs’ training by […]

Plants Inspire Exceptionally Strong and Elastic Graphene Aerogels

By Prachi Patel for C&EN

Ultralight and exceptionally strong, graphene aerogels are attractive materials for use as catalysts, electrodes, and flexible electronics. But so far it has been hard to make them both strong and elastic. Researchers have now overcome that hurdle by making a squishable graphene aerogel that mimics an aquatic plant’s highly ordered porous structure. The new, conductive […]

Making Macrocyclic Compounds for DNA-Encoded Libraries

By XiaoZhi Lim, for C&EN

A simple tweak to a tool for making macrocyclic compounds could help increase the diversity of DNA-encoded libraries used by drug developers to rapidly screen and identify promising drug candidates. Building such libraries involves attaching short, unique DNA sequences to small molecules and then reacting those DNA-tagged building blocks together to create myriad products, which […]

Nutmeg Compound is Even Cooler than Menthol

By Deirdre Lockwood for C&EN

When you rinse with a menthol-flavored mouthwash, your mouth tingles because the compound triggers a cold-sensitive ion channel in sensory neurons in your mouth. Now scientists have found a new compound that is even more chilling. Isolated from nutmeg, this new chemical is the most potent activator of that cooling channel yet found in nature. […]

Organic Onions Richer in Flavonoids

By Alla Katsnelson, for C&EN

Many grocery store shoppers believe that organic vegetables are healthier than their conventional counterparts, but studies comparing nutritional content have produced mixed results. Now, researchers have completed the first-ever multiyear field test of a crop grown with organic methods versus conventional ones. They report that organic onions contain a significantly higher amount of two types […]

Polymer Network Captures Drinking Water Contaminant

By Deirdre Lockwood for C&EN

Long-chain perfluorinated chemicals contaminate millions of Americans’ drinking water. These compounds are a legacy of industrial pollution and the use of firefighting foam at military bases and airports; they persist in the environment because of their strong carbon-fluorine bonds. Now scientists have designed a cross-linked polymer that might more effectively remove one of the more […]

Sunlight Surprise Raises Cadmium Pollution Risk

By Deirdre Lockwood for C&EN

Even though cadmium is considered a probable human carcinogen by the U.S. Environmental Protection Agency, it is still used to give some plastics and ceramics red, orange, or yellow hues. That’s because organic pigments are unstable at the high temperatures used to make these products, and pigments like cadmium red are thought to be relatively […]

Fly-Egg Profiling Method Reveals a Corpse’s ‘Time of Death’ Faster

By Louisa Dalton, for C&EN

Carrion insects are the stopwatches of death investigations. Within minutes of a body becoming a corpse, blow flies arrive. Forensic researchers have well-calibrated knowledge of different blow fly species’ growth rates and arrival order, so correctly identifying the species found on a corpse can help establish time of demise to within hours. However, the eggs […]

Thirsty MOF Sucks More Water from Air

By XiaoZhi Lim, for C&EN

Materials that reversibly trap water from air could provide a vital source of drinking water in areas where it is scarce, or offer energy-efficient air conditioning. But to be commercially viable, these materials need a large water capacity and low energy requirements during water adsorption and desorption. Now, Mircea Dincă and his research group at […]

Genetic Engineering Through Click Chemistry

By Alla Katsnelson, for 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 […]

Artificial Melanin Gets into the Skin

By Wudan Yan, for C&EN

Melanin is the pigment responsible for human skin and hair color—and it helps protect skin cells from sun damage by absorbing ultraviolet rays and scavenging free radicals. Attempting to reproduce these properties, researchers have demonstrated that nanoparticles made with artificial melanin can protect cultured skin cells from UV radiation. The research serves as an important […]
