A new study shows how a mountain fish called Schizothorax nukiangensis has extra copies of its genes that let it thrive in fast‑moving, low‑oxygen rivers. Scientists first measured the fish’s DNA size and chromosome number. They found 100 chromosomes arranged in 25 matching pairs, meaning the fis
Scientists found a tiny ocean organism doing big things. This isn't just any bacteria—it's a type of cyanobacterium called Capilliphycus salinus ALCB114379. It lives where the ocean meets land in Brazil, where tides and weather constantly change. This tough little survivor has a complete genome mapp
J. Craig Venter, a pioneer in genetics and business, passed away at 79 in San Diego after battling cancer complications. His institute, named after him, confirmed the death and noted his recent hospitalization for side effects of treatment. In the early 1990s, Venter challenged a massive $3 billion
The world of probiotics is growing fast, thanks to new computer tricks and big data tools. Scientists now use machine learning (ML) to sift through huge amounts of biological information, from DNA sequences to the chemicals bacteria produce. This new approach lets them choose promising probiotic str
In the frozen lands of Siberia, a 14, 400-year-old wolf puppy's final meal has opened a window into the past. Inside this ancient predator's stomach, scientists discovered remnants of a woolly rhino, a massive creature that once roamed the tundras of Europe and Asia. This unexpected find has allowed
Crohn's disease is a tricky condition that affects the gut. One thing that makes it worse is how it changes the bacteria living in our intestines. These tiny helpers usually play a big role in breaking down bile acids, which are important for digestion. But in people with Crohn's, this process isn't
Papayas are not just tasty fruits; they are a goldmine for scientists studying genetics and evolution. Researchers have recently cracked open the genetic code of two different types of papayas. One is used for cooking, and the other is the sweet, juicy kind you might eat fresh. By comparing these wi
In the world of sugarcane, there's a sneaky bacterium called Xanthomonas albilineans that causes leaf scald disease. It's a tiny troublemaker with a small genome, which might be why it's so good at living inside plants. Scientists recently took a close look at what this bacterium is doing inside sug
Scientists have been diving deep into the world of fish reproduction. They've been studying a unique fish called the black rockfish. This fish has a special way of having babies. It's called ovoviviparity. That means the fish's eggs develop inside the mother's body. The babies are born alive, not fr
The human gut is home to trillions of bacteria. These tiny organisms play a big role in keeping us healthy. They can also be linked to diseases like inflammatory bowel disease (IBD). Scientists have been studying these bacteria using different methods. One method is metagenomics. It helps identify b
