Sex chromosomes of birds as reservoir for jumping genes
Occurring in the genomes of most living organisms, transposable elements (TEs) are short DNA sequences that have the ability change their position. By means of various molecular mechanisms—so-called copy-paste or cut-and-paste—they can 'jump' to.....»»
Location, location, location: Snowpack storage and runoff timing in burn scars depend on site and terrain
Increasingly severe wildfires at high elevations are impacting snowpack—an important reservoir for the U.S. West. The altered landscape makes it more challenging to predict when snow will melt and how much water will be available for use......»»
Convergent evolution study sheds light on how new genes arise
Where do new genes come from? That's the question a team of biological sciences researchers from the U of A set out to answer in a new study......»»
New technique zeros in on the genes that snakes use to produce venom
Only about 10% of the world's roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that's enough for snake bites to be an important public health concern. To help better understand how snakes make their venom and how ve.....»»
New research re-envisions Earth"s mantle as a relatively uniform reservoir
Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth's mantle, according to an evaluation of volcanic hotspots published in Nature Geoscience......»»
Scientists find new epigenetic switch, revealing how genes are regulated in early development
The team of Professor Christof Niehrs at the Institute of Molecular Biology (IMB) in Mainz, Germany, has discovered that a DNA modification called 5-formylcytosine (5fC) functions as an activating epigenetic switch that kick-starts genes in early emb.....»»
Scientists quantify energetic costs of the migratory lifestyle in a free flying songbird
Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to research by the Max Planck Institute of Animal Behavior (MPI-AB). Using miniaturized loggers implanted in wild blackb.....»»
How crypto bros wrested Flappy Bird from its creator
Decadelong trademark fight culminates in new game hinting at "Web3 innovation." Enlarge / Imagine owning one of those funky birds as an NFT! (credit: Flappy Bird Twitter/X) Fans of ultra-viral mobile gaming hit Flappy Bi.....»»
Energy-saving computing with magnetic whirls
Researchers at Johannes Gutenberg University Mainz (JGU) have managed to enhance the framework of Brownian reservoir computing by recording and transferring hand gestures to the system that then used skyrmions to detect these individual gestures......»»
Remembering where your meals came from key for a small bird’s survival
For small birds, remembering where the food is beats forgetting when it's gone. Enlarge (credit: BirdImages) It seems like common sense that being smart should increase the chances of survival in wild animals. Yet for a.....»»
Organization of DNA in chromosomes can be explained by weak interactions between nucleosomes, research suggests
An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes......»»
Century-old experiment secures beer and whiskey"s future
Thanks to an experiment started before the Great Depression, researchers have pinpointed the genes behind the remarkable adaptability of barley, a key ingredient in beer and whiskey. These insights could ensure the crop's continued survival amidst ra.....»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»
Bunyip birds and brolgas: How can we better protect species important to Indigenous people?
Kamilaroi Country lies in far northwest New South Wales, past Tamworth and crossing over the Queensland border. Here, the bunyip bird (Australasian bittern, Botaurus poiciloptilus), and the brolga (Grus rubicunda or burraalga in Kamilaroi) have been.....»»
Solving the side effect problem of siRNA drugs for genetic disease treatment
Small interfering RNA (siRNA) drugs are a class of therapeutic agents that silence specific genes associated with inherited diseases. However, siRNA drugs have challenges because siRNAs often silence genes other than the target ones, causing side eff.....»»

Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»
Regulatory gene influences shape recognition in medaka fish, scientists discover
Medaka fish that lack functional Hmgn2 genes are unable to distinguish between simple shapes, revealing a new function for the regulatory gene......»»
Why the flaming carcasses of electrocuted birds keep starting Colorado wildfires
In the past two months alone, the flaming carcasses of electrocuted birds have ignited at least three wildfires in Colorado......»»
Wildlife trafficking ring killed at least 118 eagles, prosecutors say
A man helped kill at least 118 eagles to sell their feathers and body parts on the black market as part of a long-running wildlife trafficking ring in the western U.S. that authorities allege killed thousands of birds, court filings show......»»
Developing bird migration tracking with call detection technology
A research team primarily based at New York University (NYU) has achieved a breakthrough in ornithology and artificial intelligence by developing an end-to-end system to detect and identify the subtle nocturnal calls of migrating birds......»»
