Not a living fossil: How the Coelacanth recently evolved dozens of new genes
The capture of the first living Coelacanth, a mighty ocean predator, off the coast of South Africa caused quite a stir in 1938, 65 million years after its supposed extinction. It became known as a "living fossil" owing to its anatomy looking almost i.....»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
How climate change is undermining Indigenous knowledge and livelihoods in Central America
Driven by extreme heat and drought, some of the worst wildfires in living memory raged across Mexico and Central America through April and May 2024......»»
Nanopillars create tiny openings in the nucleus without damaging cells
Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells.....»»
Franklin expedition captain who died in 1848 was cannibalized by survivors
Scientists matched DNA of living descendent to Capt. James Fitzjames of the HMS Erebus. Scientists at the University of Waterloo have identified one of the doomed crew members of.....»»
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......»»

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.....»»
The biological marvels of the seabed are being mined to create commercial products—here are the risks
Thousands of genes from deep-sea marine life are being used to create new commercial products ranging from pharmaceuticals to cosmetics. Genes are segments of DNA that provide instructions for making other molecules that are essential for the structu.....»»
Advancing green chemistry: A tandem catalyst for efficient biomass conversion
The global demand for sustainable energy sources has intensified the search for environmentally friendly alternatives to fossil fuels. Biomass waste, a byproduct of various industrial processes, presents an untapped potential for the production of bi.....»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
New fossil species reshapes understanding of grape family history
Until now, it was believed that plants of the grape family arrived at the European continent less than 23 million years ago. A study on fossil plants draws a new scenario on the dispersal of the ancestors of grape plants and reveals that these specie.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
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.....»»
New evolutionary model revises the origins of biodiversity
An international team of scientists has made a discovery that could reshape our understanding of how global biodiversity evolved. By reconstructing the evolution of species over the past 45 million years, researchers found that the geographic origins.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Studying fossil extraction on Native lands and exploring the depths of untold histories
In 2019, historian Lukas Rieppel published a book about the history of dinosaur fossils and their excavation in the late 1800s to create museum displays......»»
