Colossal Biosciences Claims First De-Extinction with “Return” of the Dire Wolf

Biology /

In a scientific breakthrough that feels ripped from the pages of Jurassic Park or Game of Thrones, Colossal Biosciences, the world’s only de-extinction company, has announced the birth of three wolf pups that it claims mark the world’s first successful de-extinction event. The company says these pups, modeled after the long-extinct dire wolf, bring a […]

For the First time, Scientists Observe Living Plant Cells Producing Cellulose and Constructing Cell Walls

Biology, Cell Biology /

In a pioneering study on cellulose synthesis, a key component of plant cell walls, researchers at Rutgers University-New Brunswick have recorded continuous images of living plant cells constructing cell walls over 24 hours. Their findings offer valuable insights that could help develop stronger plants for enhanced food production and more affordable biofuels. Published in Science

Tiny electrical discharges between water droplets may have ignited the spark of life on Earth.

Biology /

Dr. Frankenstein may not have needed a lightning bolt to spark life after all. A new Stanford study suggests that constant “microlightning” between water droplets could have provided the jolt that jumpstarted life on Earth. One of the biggest mysteries in evolution is how life emerged from non-living matter. Scientists believe early Earth contained a

Directly Transforming Skin Cells into Brain Cells Achieves a Tenfold Increase in Success

Biology /

MIT scientists have made a significant breakthrough in regenerative medicine by developing a highly efficient method to convert skin cells directly into brain cells, eliminating the need for an intermediate stem cell stage. Traditionally, generating stem cells for medical treatments required harvesting them from embryonic tissue, raising ethical concerns. That changed in 2006 when Japanese

Stem Cell Therapy Trial Restores Vision by Healing Corneal Damage

Biology /

Eye injuries that damage the cornea often lead to permanent blindness, with few treatment options available. However, a new clinical trial has successfully restored vision in patients by transplanting stem cells from their healthy eyes. The cornea, the eye’s outermost layer, plays a crucial role in focusing light toward the retina. Because it constantly faces

Flagellar Motors: The Secret Behind Bacteria’s Nearly 100% Energy Efficiency

Biology /

When people think of motors, they typically envision those in vehicles or machines. However, biological motors have existed for millions of years, especially in microorganisms. Many bacteria rely on tail-like structures called flagella, which rotate to propel them through fluids. This movement is powered by a protein complex known as the flagellar motor. The flagellar

Octopuses Have a Hidden Sex Chromosome That Predates Dinosaurs

Biology /

University of Oregon researchers have discovered a sex chromosome in the California two-spot octopus that likely dates back 480 million years—long before octopuses and nautiluses diverged. This makes it one of the oldest known animal sex chromosomes. The finding confirms that octopuses and other cephalopods, including squid and nautiluses, use chromosomes to determine sex, solving

Watch: Scientists Create the World’s First Lab-Grown Kangaroo Embryo

Biology, Evolution /

For the first time, scientists have successfully created kangaroo embryos using in-vitro fertilization (IVF), marking a significant breakthrough in efforts to replicate this process across hundreds of marsupial species increasingly at risk of extinction. A research team from the University of Queensland achieved this feat using eggs and sperm from eastern grey kangaroos (Macropus giganteus),
