Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence how genes function, affecting which are switched on and when. Studying how DNA responds to stress can help scientists better understand how genes are controlled, how the molecule is organized, …

Bearded dragons are famous for their ability to change sex depending on heat and genes. Two new genome projects have revealed the likely master gene, Amh, behind this switch — finally solving a reptile mystery that has baffled scientists for years. Credit: Shutterstock Scientists have finally cracked one of the strangest mysteries in reptile biology: how bearded dragons decide their …

Here’s what you’ll learn when you read this story: A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed neutrinos implied by the mirror universe. Scientists believe there could be an “anti-universe” somewhere out there that looks like the …

Red supergiant DFK 52 and its surroundings as seen by ALMA. The vast, complex bubble blown by this extreme star is about 1.4 light-years across, thousands of times wider than our Solar System. ALMA measures light invisible to the human eye, with a wavelength of around 1.3 millimeters, emitted by molecules of carbon monoxide and silicon monoxide. Thanks to the …

Scientists have engineered a strain of bacteria with a genetic code unlike anything found in nature, marking a groundbreaking advance in synthetic biology. The microbe, called Syn57, is a lab-made version of Escherichia coli, a bacterium that normally causes infections in the gut, urinary tract and other parts of the body. Unlike all known life, which relies on 64 codons, …

As annoying as catching a cold may be, there could be a silver lining. New research suggests that it may temporarily protect you from getting covid-19. Researchers revealed that individuals, especially children, who had recently been infected by a rhinovirus—the most frequent culprit behind the common cold—were remarkably less likely to get a SARS-CoV-2 infection, the virus that causes covid-19, …

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth’s history. Our history. Research shows there are little-known chapters in that history, deep within Earth’s past. In fact, Earth’s inner core appears to have another even more inner core within it. “Traditionally we’ve been taught …

Scientists in Japan have unveiled a revolutionary bacteria-based therapy that eradicates tumors without relying on the immune system, offering fresh hope for patients where standard treatments fail. Credit: Stock Two bacteria working in harmony show powerful antitumor effects. The approach could transform treatment for immunocompromised patients. A research team led by Professor Eijiro Miyako at the Japan Advanced Institute of …
