Green solvents, such as supercritical CO2, can replace harmful organic solvents in laboratories. Many sustainable lab methods will be showcased at Lab Innovations 2023 which is scheduled to take place from November 1–2 at the NEC, Birmingham in the United Kingdom.

Researchers have developed a new portable, wearable device that has the capacity to detect hidden hormone spikes which can lead to high blood pressure as well as other health conditions.

Why do large dogs tend to live shorter lives? A study of 864 dogs links body size to faster loss of DNA methylation at regions containing “jumping genes”. The findings offer a possible molecular explanation for differences in canine ageing, although whether these changes help drive ageing remains unclear.

Unusual tooth wear and chemical traces in ancient human remains suggest that hunter-gatherers in Indonesia were using betel nuts up to 25,000 years ago. The findings push the practice back into the Ice Age and point to a long history of psychoactive substance use and its dental consequences.

Although the pH scale traditionally ranges from 0 to 14, highly concentrated acids can have negative pH values. Accurately measuring these extremes poses technical challenges for standard electrodes. This article explains how specialized sensors and modern methods enable reliable measurements in such chemical extremes.

New research highlights that food anaphylaxis, a severe and rapid allergic reaction to food, can prove fatal in children if life-saving adrenaline autoinjector (Epipen) is not administered on time.

Treating salty industrial wastewater and recovering valuable metals has long required separate processes. A new electrochemical platform combines both tasks in a single step, improving water reuse while reducing waste and downstream processing.

An unusually well-preserved snake fossil from Brazil is adding a new dimension to the debate over how snakes evolved. Hidden within its 80-million-year-old skull, researchers have uncovered clues to how the animal lived and sensed its surroundings.

Modern, targeted laboratory diagnostics enables optimal treatment. At the Labmed Forum, held alongside MEDICA in Düsseldorf from 16 to 19 November, experts and companies will showcase emerging trends and developments in diagnostic methods.

New research from Virginia Tech identifies key molecular changes behind age-related memory loss — and shows they can be reversed. By targeting specific brain processes with advanced gene-editing tools, scientists improved memory performance in older animals, opening new possibilities for dementia research.
