How genetic islands form among marine molluscs
Usually, the individuals of a population of marine species that have the potential to disperse over long distances all share a similar genetic composition. Yet every now and then, at small, localized sites, small groups of genetically different indiv.....»»
Researchers reveal key mechanism in regulating DNA recombination
Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This process requires a set of recombinases polymerized on single-stranded (ss) DNAs called the nucleoprotein filament to undergo h.....»»
Low stream diatom biodiversity potentially decreases stream oxygen production in remote islands
Benthic diatoms are the most important and biodiverse primary producers in streams and comprise the basis for the food webs, fueling animals such as insects and stream fishes including trout......»»
How future heat waves at sea could devastate UK marine ecosystems and fisheries
The oceans are warming at an alarming rate. 2023 shattered records across the world's oceans, and was the first time that ocean temperatures exceeded 1°C over pre-industrial levels. This led to the emergence of a series of marine heat wave events ac.....»»
Genetic database shows some fungal crops became completely reliant on ants 27 million years ago
When humans began farming crops thousands of years ago, agriculture had already been around for millions of years. In fact, several animal lineages have been growing their own food since long before humans evolved as a species......»»
Plants have a backup plan to pass down accurate chromosome copies
Tending a garden is hard work. Imagine it from the plants' perspective. Each relies on fine-tuned genetic processes to pass down accurate copies of chromosomes to future generations. These processes sometimes involve billions of moving parts. Even th.....»»
The best 60 percent keyboards for 2024
If you don't have a ton of desk space, a small keyboard is best. Here are some of the best 60 percent keyboards if you care for the small form factor......»»
AI models identify marine biodiversity hotspots in Mozambique
A new study led by staff from the Wildlife Conservation Society (WCS) in East Africa has used a predictive artificial intelligence (AI) algorithm to confirm the location of previously-unmapped high marine biodiversity areas along Mozambique's extensi.....»»
Chemist challenges traditional views on crystal growth
Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that your understanding of how crystals formed in those so.....»»
London Standard"s AI-generated review, by late art critic Brian Sewell, exposes a significant philosophical threat
For the first issue in its new weekly print edition, the London Standard has run an experiment in the form of an AI-generated review of the National Gallery's Van Gogh: Poets and Lovers exhibition, written in the style of late art critic Brian Sewell.....»»
Preserving nature"s genetic resources: Wild banana relatives of mainland Southeast Asia reveal hidden diversity
In a new study, researchers have uncovered a wealth of hidden diversity among wild banana species in mainland Southeast Asia. The discovery, which has been published in PLoS ONE, highlights the critical importance of conserving these genetic resource.....»»
Lian Li’s $70 small form factor case just became my daily driver
The Lian Li A3-mATX offers an excellent balance of price, build quality, and compatibility with large PC components......»»
Researchers determine how a protein contributes to human immune defense against RNA viruses
An international research team led by Prof. Dr. Janosch Hennig from the University of Bayreuth has discovered how the TRIM25 protein contributes to defense against RNA viruses whose genetic material is contained as ribonucleic acid (RNA)......»»
Bottlenose dolphins "smile" at each other while playing, research shows
Dolphins are extremely playful, but little is known about how they—and other marine mammals—communicate during playtime. New research published October 2 in the journal iScience shows that bottlenose dolphins (Tursiops truncates) use the "open mo.....»»
Scientists find plausible geological setting that may have sparked life on Earth
Researchers have discovered a plausible evolutionary setting in which nucleic acids—the fundamental genetic building blocks of life—could enable their own replication, possibly leading to life on Earth......»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»
Scientists fear underfunded Argentina research on verge of collapse
Argentine biochemist Alejandro Nadra worries that President Javier Milei's budget cuts will undo his scientific quest to unravel the cause of genetic diseases that disable and kill millions......»»
Breeder who tried to create enormous trophy sheep jailed in US
A man who tried to breed enormous hybrid sheep using genetic material from endangered animals so he could sell them to trophy hunting ranches has been sentenced to six months in prison, the US Department of Justice said Monday......»»

Researchers witness nanoscale water formation in real time
For the first time ever, researchers have witnessed—in real time and at the molecular-scale—hydrogen and oxygen atoms merge to form tiny, nano-sized bubbles of water......»»
DNA technology enables molecular monitoring for marine change and threats
New DNA technology promises to improve efforts to monitor marine life in the Southern Ocean, and detect the presence of non-native marine species close to Antarctica......»»
