Bacterial genome is regulated by an ancient molecule
We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes......»»
Centuries ago, the Maya storm god Huracán taught that when we damage nature, we damage ourselves
The ancient Maya believed that everything in the universe, from the natural world to everyday experiences, was part of a single, powerful spiritual force. They were not polytheists who worshipped distinct gods but pantheists who believed that various.....»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Intel and Google Cloud team up to launch super-secure VMs
Google Cloud and Intel have joined forces to create new super-secure Confidential Computing instances for regulated industries......»»
Study traces wild cat eye color diversity to ancient ancestor
Fans of Clementine, the cat who recently captivated TikTok with her rare eye color, should take note. The piercing golden gaze of cheetahs, the striking blue stare of snow leopards, and the luminous green glare of leopards are all traits that can be.....»»
Webb telescope detects unusual gas jets from Centaur 29P
Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the sun between Jupiter and Neptune. NASA's James Webb Space Telescope has mapped.....»»
Iron nuggets in the Pinnacles unlock secrets of ancient and future climates
Small iron-rich formations found within Western Australia's Pinnacles, which are part of the world's largest wind-blown limestone belt spanning more than 1,000km, have provided new insights into Earth's ancient climate and changing landscape......»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Fluorescent molecules to illuminate life: Simplified synthesis with formaldehyde
A research team has recently made a breakthrough in synthesizing organic fluorophores more cost-effectively and atom-efficiently than ever before by using formaldehyde, the simplest carbon molecule. Their findings were published in Angewandte Chemie.....»»

Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
New method enables noninvasive plant magnetic resonance imaging
The "omics" technologies—genomics, transcriptomics, proteomics, and metabolomics—are at the forefront of discovery in modern plant science and systems biology. In contrast to the rather static genome, however, the metabolome and the products meas.....»»
How old is beer?
Humans are no strangers to kicking back with a cool pint of beer. The Ancient Egyptians, for example, had a hankering for beer that was a little bit tart, almost like a modern-day gose, a lemony beer from Germany. Homer, the Ancient Greek poet, spoke.....»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Study shows that ancient reef-building stromatoporoids dodged extinction—at least temporarily
Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet—for a while, at least......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Medicinal tree successfully grown from 1,000-year-old seed found in cave
An international team of botanists, agriculturists and historians has successfully grown a mature tree from an ancient seed found in a cave in Israel. In their paper, published in the journal Communications Biology, the group describes where the seed.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
