It's been around 15 years since the introduction of the NOVA food-processing classification. Originally designed to pinpoint ultra-processed foods linked to noncommunicable diseases, NOVA has a broader scope that aligns with sustainable nutrition. But how well does NOVA fit with other indicators of
Ever heard of nanosheets that are just a few atoms thick but packed with amazing light-absorbing abilities? Scientists have made such nanosheets using a mix of gallium arsenide and aluminum gallium arsenide, called GaAs/AlGaAs. These super-thin nanosheets have special light properties that make them
Researchers checked how cows from South Dakota (SD) and Texas (TX) grew and changed when finished in either state. They divided 190 heifers (weighing around 483 kg from SD and 425 kg from TX) into four groups based on their origin and finishing location. They weighed the heifers regularly, and some
Get ready to watch a celestial spectacle! This January, you can spot five planets in the night sky with your naked eye, and even catch a glimpse of two more with a telescope. Imagine seeing Venus, Saturn, Jupiter, and Mars all at once! Plus, Uranus and Neptune are part of the squad too, but you'll n
Understanding when bacteria first emerged on Earth is a big puzzle, mainly because bacteria fossils are rare. Scientists have found a new way to solve this puzzle by looking at ancient partnerships between bacteria and other life forms. They used genes found in mitochondria–the tiny powerhouses insi
Ever wondered how marine bacteria talk to algae? Chemical communication between these tiny ocean dwellers influences their populations and affects crucial ocean processes. A recent discovery sheds light on this hidden language. Scientists were studying the bacterium Roseovarius tolerans, which lives
Scientists often use genetic data to figure out how closely related different organisms are. One common way they do this is by using something called a Markov substitution model. This model helps them understand how changes, or substitutions, happen in molecular sequences over time. The general time
Ever wondered why some people are great at recognizing faces while others struggle? Scientists are exploring this mystery by looking at something called "face-space. " Imagine face-space as a map where each face has a spot. On this map, similar faces are close together, and very different faces are
Have you ever wondered how fish survive in different types of water? Scientists have been studying this adaptation in Eurasian perch. They looked at the genes of perch from 42 different populations using whole-genome sequencing. By comparing individuals and pooled samples, they found over 2, 600 gen
Scientists created four unique materials by mixing organic and inorganic parts. Two of these, known as compound 1 and 2, had a layered structure. Compound 2, however, stood out with a special tubular design made of pyridine, which was linked to a negatively charged ion. These materials, known as POM
