Geneticists who sampled 243 boars and pigs around the Fukushima nuclear plant confirmed escaped farm pigs had bred into the wild boar herd, but the pig ancestry is erasing itself — hybrid sows inherit year-round breeding from domestic mothers, and faster generations dilute the pig genes faster
1+ hour, 3+ min ago (371+ words) A decade after Fukushima's evacuation, escaped farm pigs bred with wild boars—but nature is erasing the domestic legacy faster than anyone predicted. By Science Blog Editorial Team Published September 13, 2026 · How we edit When the sirens emptied the towns around…...
New computational tool reads hidden RNA cleavage signals in health and
33+ min ago (747+ words) For years, biologists catalogued small non-coding RNAs by counting how many of each type appeared in a sequencing run. That approach treated tiny RNA molecules as a census problem, and it worked well enough for microRNAs, the classical regulators of…...
DartUniFrac Brings Megascale Computing to Microbiome Diversity Analysis
1+ hour, 4+ min ago (512+ words) Researchers have introduced DartUniFrac, a new software tool designed to carry out UniFrac-based microbiome comparisons at a scale that was previously impractical....
New Rust Toolkit Supercharges Sex Determination Studies in Non-Model
1+ hour, 24+ min ago (628+ words) A new open-source software package promises to transform how biologists hunt for the genetic switches that separate males from females in species with no reference genome....
Mole-Rat Genes Evolving Faster Than Expected Reveal Secrets of Subterranean
1+ hour, 47+ min ago (568+ words) Beneath the sun-baked soils of eastern and southern Africa, a family of rodents has quietly rewritten the rules of mammalian life. Naked mole-rats resist cancer, tolerate near-anoxic conditions and barely age. Damaraland mole-rats dig elaborate tunnel networks and live in…...
SIRT1 Silences Jumping Genes by Stabilizing Heterochromatin Complexes
1+ hour, 55+ min ago (55+ words) Deep within the human genome lies an ancient threat. Long interspersed elements-1, known as LINE-1 or L1, are the only autonomous transposable elements still active in our DNA, making up roughly 17 percent of the genome. When these genetic parasites leap to…...
Teeth Under Fire: Time, Not Just Temperature, Decides DNA Survival
2+ hour, 55+ min ago (87+ words) When fire consumes a home, a vehicle, or an aircraft, one of the most pressing questions facing investigators is whether the victims can be identified at all. Extreme heat shreds DNA into fragments too small to analyze, and forensic teams…...
No cause of death determined for minke whale, further testing to be done
1+ day, 12+ hour ago (171+ words) No cause of death has been determined following an hours-long necropsy for the minke whale that washed up on Rocky Neck. A dead, female minke whale that washed up on Rocky Neck is towed through Gloucester Harbor by the harbormaster…...
Fences Alone Cannot Save Desertified Alpine Grasslands, Soil Study Reveals
5+ hour, 16+ min ago (576+ words) High on the Qinghai-Xizang Plateau, the world’s most extensive alpine grasslands are quietly losing their ability to heal themselves. For decades, land managers have assumed that simply fencing off overgrazed pastures and letting nature take its course would be enough…...
Duplicated Energy Genes Reveal How Fish Mitochondria Evolved After Genome
5+ hour, 34+ min ago (620+ words) Every heartbeat, every twitch of a fin, and every dividing cell in a fish embryo depends on a molecular machine so ancient that its origins trace back billions of years. Oxidative phosphorylation, or OXPHOS, is the process by which cells…...
