DNA duplication linked to the origin and evolution of pine trees and their relatives
Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are then free to mutate and produce new.....»»
Mars analog stations investigate lichen biodiversity during simulated missions
Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. The.....»»
Evolution in real time: Scientists predict—and witness—evolution in a 30-year marine snail experiment
Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species.....»»
How did the building blocks of life arrive on Earth? Zinc fingerprints in meteorites offer clues
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough of these compounds on Earth f.....»»
Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Hidden in the teeth: DNA study finds these 19th century lions preyed on humans and giraffes
In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The lions, which were massive and maneless, crept into the camp at night, raided the tents and dragged off their victims. The infamous Tsavo "man-eaters".....»»
Up in smoke: DIY tech to combat wildfires
As wildfires become a more frequent and dangerous part of life, especially in the Pacific Northwest, finding solutions that everyone can use is more important than ever. By June 2024, the Pacific Northwest had already seen more trees burn than in all.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Animal social interactions could speed up evolution
Scientists typically predict how species evolve by looking at their genes and the environment they live in, but new research from the University of Aberdeen has highlighted a key factor that's often overlooked: social interactions, where the genes of.....»»
Huge waves in the atmosphere dump extreme rain on northern Australia
In 2023, almost a year's worth of rain fell over ten days in parts of northwestern Australia, leading to catastrophic flooding in the town of Fitzroy Crossing and surrounds. The rainfall was linked to a tropical cyclone, but there were also lesser-kn.....»»
Fall is here: Why do some trees lose their leaves while others stay green?
The autumn has arrived and northeastern North America's forests will soon grace us with a breathtaking palette of reds, yellows and golds. These vivid colors will then fade, giving way to bare branches, as the fallen leaves blanket the forest floor,.....»»
Using a unique combination of DNA techniques to authenticate ginseng supplements and combat adulteration
Rosalee Hellberg, an associate professor in Chapman University's Food Science Program, and her research team have made a significant breakthrough in the fight against adulteration in dietary supplements. Effective methods for identifying adulteration.....»»
One dead as storm Kirk tears through Spain, Portugal, France
The remnants of Hurricane Kirk swept into western Europe Wednesday, tearing up trees in Portugal and Spain before dumping heavy rains on France that left at least one dead......»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
Africa"s Great Green Wall will only combat desertification and poverty by harnessing local solutions, say researchers
In the rural village of Téssékéré, the increasing number and intensity of droughts linked to climate change is making the lives and livelihoods of the local Fulani communities increasingly vulnerable. Here, in the northern Sahel desert region of.....»»
New seed fossil sheds light on wind dispersal in plants
Scientists have discovered one of the earliest examples of a winged seed, gaining insight into the origin and early evolution of wind dispersal strategies in plants......»»
US finalizes rule to remove lead pipes within a decade
President Joe Biden's administration on Tuesday finalized a rule mandating the removal of the nation's remaining lead pipes within a decade, a move aimed at preventing millions of people from being exposed to the toxic metal linked with childhood dev.....»»
Data Theorem Code Secure helps security and DevOps teams secure their software
Data Theorem launched Code Secure, the latest evolution in application security designed to protect the software supply chain from code to deployment. Code Secure uniquely integrates Static Application Security Testing (SAST), Software Composition An.....»»
EVs, China and an election make for a turbulent political stew in Michigan
It is complicating Michigan’s efforts to lead the next stage of automotive evolution and highlighting geopolitical tensions with China......»»
Sperm whale departure linked to decline in jumbo squid population in Gulf of California
A PeerJ study has revealed a significant departure of sperm whales (Physeter macrocephalus) from the central portion of the Gulf of California, is linked to the collapse of the jumbo squid (Dosidicus gigas) population, their primary prey......»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
