Rare Italian Forest Herb Defies Expectations With Surprising Genetic
42+ min ago (77+ words) Deep in the mountain forests of southern Italy, a rare blue-flowered herb has been quietly rewriting what scientists think they know about plant rarity. Aegonychon calabrum, a perennial understory herb restricted to a handful of sites in the southern Apennines,…...
DartUniFrac Brings Megascale Computing to Microbiome Diversity Analysis
1+ hour, 32+ 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, 52+ 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....
Heart cells can ‘remember’ stress and use it for protection during chemotherapy
6+ hour, 14+ min ago (1157+ words) Early stress in mitochondria before birth helped mouse hearts resist later chemotherapy damage by creating lasting protective changes. Chemotherapy can save lives, but some drugs can also put the heart under serious strain. Doxorubicin, a chemotherapy used against several cancers,…...
Mole-Rat Genes Evolving Faster Than Expected Reveal Secrets of Subterranean
2+ hour, 15+ 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
2+ hour, 23+ 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…...
Grapevine Gene VvbHLH10 Doubles as a Salt-Alkali Shield and Bud Growth
3+ hour, 18+ min ago (509+ words) A single transcription factor in grapevine has emerged as a double agent in plant biology, simultaneously arming vines against one of agriculture’s most punishing soil stresses while also coaxing dormant buds into active growth....
Teeth Under Fire: Time, Not Just Temperature, Decides DNA Survival
3+ hour, 23+ 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…...
Hidden RNA Switch Helps Esophageal Cancer Evade Ferroptotic Cell Death
4+ hour, 27+ min ago (73+ words) Esophageal cancer remains one of the most lethal malignancies worldwide, and a new study published in Cellular and Molecular Life Sciences has uncovered a previously hidden molecular mechanism that helps these tumors survive. Researchers led by Yi Zhang, Tao Yan,…...
Dark DNA’s Long RNAs Emerge as Master Regulators of Colorectal Cancer
5+ hour, 45+ min ago (90+ words) For decades, the vast stretches of the human genome that do not encode proteins were dismissed as evolutionary baggage, a biological wasteland dismissed with the shorthand of “junk DNA.” A comprehensive new review published in Nature Reviews Gastroenterology & Hepatology makes…...
