Research provides new design principle for water-splitting catalysts

PROVIDENCE, R.I. [Brown University] — Scientists have long known that platinum is by far the best catalyst for splitting water molecules to produce hydrogen gas. A new study by Brown University researchers shows why platinum works so well — and…

Comparing heirloom and modern wheat effects on gut health

Amid concerns about gluten sensitivity, increasing numbers of people are avoiding wheat. Most have not been diagnosed with a wheat-related medical condition, yet they seem to feel better when they don’t eat gluten-containing foods. A possible explanation is that modern…

Reflecting on the year in chemistry

A lot can happen in a year, especially when it comes to science. As 2019 draws to a close, Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, is highlighting the year’s biggest stories in chemistry,…

Saccharin derivatives give cancer cells a not-so-sweet surprise

Saccharin received a bad rap after studies in the 1970s linked consumption of large amounts of the artificial sweetener to bladder cancer in laboratory rats. Later, research revealed that these findings were not relevant to people. And in a complete…

Watered down biodiversity: sample type is critical in environmental DNA studies for biomonitoring

DNA-based biomonitoring relies on species-specific segments of organisms DNA for their taxonomic identification and is rapidly advancing for monitoring invertebrate communities across a variety of ecosystems. The analytical approaches taken vary from single-species detection to bulk environmental sample analysis, depending…

Membrane inspired by bone and cartilage efficiently produces electricity from saltwater

Inspired by membranes in the body tissues of living organisms, scientists have combined aramid nanofibers used in Kevlar with boron nitride to construct a membrane for harvesting ocean energy that is both strong like bone and suited for ion transport…

In global south, urban sanitation crisis harms health, economy

ITHACA, N.Y. – Cities in the “global south” – densely populated urban areas that are part of low-income countries in Asia, Africa and Latin America – should phase out pit latrines, septic tanks and other on-site methods of human waste…

Star fruit could be the new ‘star’ of Florida agriculture

It’s not just oranges that grow in Florida. Carambola, or star fruit as most in the United States call it, is gaining popularity. One researcher from Florida International University is researching how cover crops can help the sustainability of star…

Topological materials for information technology offer lossless transmission of signals

New effects in solid-state physics are often first discovered at temperatures near absolute zero (0 Kelvin or -273 °C). Further research can then determine whether and how these phenomena can be induced at room temperature as well. So it was…

A soft robotic insect that survives being flattened by a fly swatter

Imagine swarms of robotic insects moving around us as they perform various tasks. It might sound like science fiction, but it’s actually more plausible than you might think. Researchers at EPFL’s School of Engineering have developed a soft robotic insect,…

Scientists identify harmful bacteria based on its DNA at a very low cost

The detection of food poison outbreaks caused by bacteria takes time and is expensive, but now researchers have found a cheap method for the precise identification of bacteria in just a few hours on a mobile-phone-sized device

Online hate speech could be contained like a computer virus, say Cambridge researchers

The spread of hate speech via social media could be tackled using the same “quarantine” approach deployed to combat malicious software, according to University of Cambridge researchers. Definitions of hate speech vary depending on nation, law and platform, and just…

Australian desalination plant attracts fish

With growing populations and climate uncertainty, water security is a global concern. Many nations operate desalination plants, which remove salt from seawater to make it drinkable. These facilities typically discharge excess salt as hypersaline brine back into the ocean, with…
