Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as ...

A practical look at common tape measure use on the job site, with a focus on accurate measuring and better building habits. What small measuring mistake do you see most often? Pauline Hanson’s stance ...

Humans are animals that measure things. Call us Homo mensura. We have a compulsion to quantify, and for millennia we’ve been inventing new ways to go about it. For anything you can think of, there’s a ...

Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By ...

There are photosynthetic bacteria known as cyanobacteria, and these microbes helped generate the oxygen that paved the way for complex life to survive on Earth. Researchers have now found that these ...

Sunday is the longest day of the year for half the planet. A guide to the summer solstice Ancient teeth from Siberia rewrite the plague’s timeline, dating back to over 5,500 years ago A primer on ...

We introduce an improved measure of geopolitical risk that builds on Caldara and Iacoviello (2022) and uses artificial intelligence to evaluate newspaper content. Our approach replaces keyword ...

Scientists have developed instruments capable of measuring forces so small they are almost impossible to imagine. In specialized laboratories, devices like electrostatic force balances and microscopic ...

Even before the AI boom, data centers were already consuming staggering amounts of energy and natural resources. Now, generative AI has intensified that strain, exposing just how unsustainable our ...

DNA from gloves found two miles from the crime scene did not match any profiles in the CODIS system. The FBI is using genetic genealogy in the Nancy Guthrie investigation. DNA from gloves found near ...

Researchers at the Johns Hopkins Kimmel Cancer Center have developed a novel liquid biopsy approach to identify early-stage cancers by measuring the random variation in DNA methylation patterns, ...

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes ...
