Making scents of cannabis: How cannabis cultivar and preparation methods influence aroma

Ongoing research reveals how the aroma of cannabis is influenced not only by the chosen cultivar, but also by different drying and storage methods. Through a combination of high-resolution chromatography and human-perception aroma assessments, this project provides detailed insig

Cheetah chases inspire researchers to make a biologically accurate video game

Movement data from wild predator–prey encounters and controlled human catch-tag games have been combined to create realistic simulations of high-intensity movement dynamics and energetics—before being transformed into a publicly accessible video game. This game uses a citizen sci

Birds' efficient red blood cells convert metabolic 'waste' into fuel for rapid recovery

New research finds that birds can use lactate, often thought of as a metabolic waste product, as a cellular fuel that aids in rapid recovery from a harmful state that impairs oxygen delivery. Hemoglobin, the protein that carries oxygen to our tissues, naturally converts to methem

New ultrathin lens focuses light into an optical needle

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence tomography (OCT) could allow imaging that reaches deeper

Parasites deliver long-chain omega-3 fatty acids to aquatic systems, feeding endangered fi

Wormlike parasites cause crickets to jump into streams, where the fatty insects nourish endangered fish. Ayano Medo and Takuya Sato sought to characterize the flow of eicosapentaenoic acid (EPA)—a nutritious long-chain omega-3 fatty acid—through aquatic and terrestrial ecosystems

How cells keep genomic hitchhikers under control

Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become active again at the wrong time. Now, two studies published
