Genetic Barcodes Reveal How Chromosomes Recognize Each Other

by

Repetitive satellite DNA sequences in fruit flies function as chromosome-specific barcodes that help matching chromosome pairs find each other during meiosis, according to research published in Nature Communications. When ETH Zurich scientists Lena Skrutl and Madhav Jagannathan disrupted these satellite DNA patterns on two chromosome pairs simultaneously, pairing errors increased sharply and the DNA-binding protein … Read more

Ancient Supercontinent Covered 80% of Earth, Scientists Discover

by

A new global isotopic map reveals that vast fragments of ancient Gondwanan crust are buried beneath younger mountain belts across Asia, Europe, and North America, indicating the landmass was substantially larger than previously recognized. Based on findings published in Science Advances by Curtin University researchers, incorporating these recently discovered pieces increases Gondwana’s calculated proportion from … Read more

22-Million-Year-Old Andes Landscape Preserved by Giant Pompeii-Scale Eruption

by

An explosive volcanic eruption in northern Chile nearly 22 million years ago buried an ancient Andean landscape under more than 1,260 cubic kilometers of hot ash, pumice, and gas, creating a geological time capsule that reveals how slowly the mountains rose, according to a study published in Science Advances. How the Cardones Ignimbrite Preserved Northern … Read more

New ‘Google-like’ Search Engine Scans Millions of Cells for RNA Clues

by

According to research published in the journal Nature, a new search platform called Malva enables scientists to search RNA sequences across millions of individual cells in seconds without downloading enormous raw datasets or mapping them against a reference genome. Developed by creators including Nikolaus Rajewsky, Daniel León-Periñán, and Nikos Karaiskos, the system has indexed more … Read more

How Your Body Ignores Sweat in Sweltering Heat

by

Sweat evaporation fails to cool the body effectively in hot, dry, and windless conditions because competing air currents near the skin cancel each other out, according to a study led by Arizona State University researchers. The findings reveal a hidden physics problem in human heat balance that can cause core body temperature to rise nearly … Read more

New Light Wave Equation Challenges the Arrow of Time

by

A newly formulated accelerating wave equation developed by researchers at the University of Eastern Finland and Tampere University suggests that accelerating waves can move only toward positive time, providing a potential microscopic explanation for a preferred direction of time. According to the theoretical analysis published in the journal Optica, treating changing wave speeds as relativistic … Read more
