Researchers found that many snakes are carrying multiple infections at once, with a dangerous fungal disease called ophidiomycosis — or snake fungal disease — emerging as one of the biggest threats. Pygmy rattlesnakes appeared especially vulnerable, frequently infected with both the fungus and a parasitic “snake lungworm.” Tue, 26 May 2026 07:29:57 EDT https://www.sciencedaily.com/releases/2026/05/260526021950.htm https://www.sciencedaily.com/releases/2026/05/260525000459.htm Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may have helped it gulp air and a light-sensitive organ linked to day-night rhythms.

Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic material — a mistake linked to aging, cancer, and other major diseases. Researchers discovered that not all of these failures are equal.

By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The findings could help conservationists identify safer new habitats and establish backup populations before disasters like bushfires wipe them out.

Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent “zombie cells,” which are linked to aging, cancer, and neurodegenerative disease. The method could eventually help scientists identify and target these cells in living tissue with far greater precision.

By analyzing traces of DNA floating in seawater from depths exceeding 4 kilometers, researchers identified 226 species ranging from deep-diving whales to strange fish rarely or never seen in the region before. Some of the creatures may even be unknown to science. Thu, 14 May 2026 08:46:07 EDT https://www.sciencedaily.com/releases/2026/05/260513221807.htm
