Researchers have developed a new laboratory model grown from stem cells that replicates the human amniotic sac in the first two to four weeks after fertilization. The structure, which the researchers say is the most advanced and mature amniotic model ever created, could offer new insight into human development and lead to cell products for medical procedures, from burn treatments …

A scientist’s cat shot to fame last year for his role in the discovery of the United States’ first-known jeilongvirus. Now, the feline has replicated his success by fetching yet another animal containing a never-before-seen bug. The newfound virus was found in a dead Everglades short-tailed shrew (Blarina peninsulae), which Pepper the cat brought home following a successful hunting trip …

Botanists confirmed recently that a towering tree discovered in Tanzania’s Udzungwa Mountains is an entirely new species, Tessmannia princeps. The research team is led by Andrea Bianchi, a horticulturist and researcher at Muse Science Museum in Trento, whose group worked with Tanzanian experts to document the species and its remote habitat. Discovering Tessmannia princeps Bianchi and local plant …

Researchers have recreated the tumultuous beginnings of Earth, simulating what the planet was like just after its formation 4.5 billion years ago. The results, derived from a new computer model, provide a fascinating insight into the fiery youth of our planet, uncovering how Earth’s molten early years shaped its current geological structure. A Molten World Cooled in Layers When Earth …

Giant sand mounds beneath the North Sea have puzzled scientists for years. Now, researchers have discovered that these mysterious structures were created by a geological process that has never been seen on such a huge scale. Seismic data and rock samples from the northern North Sea, off the coast of Norway, suggest that these miles-wide mounds sank millions of years …

Earth started out as a ball of liquid fire, its newborn surface closer to a lava lamp than the calm continents we know today. Those incandescent beginnings happened 4.5 billion years ago, yet the evidence is buried miles beneath our feet where direct sampling is impossible. A new computer model of the infant planet’s mantle says the rock we stand on …

The blue shark (Prionace glauca) might be more than its name. Scientists investigating the sleek ocean predator’s skin discovered nanostructures that not only produce its signature hue, but also potentially let it change color like a chameleon. Animals produce their colors in various ways. Some rely on pigmented cells that reflect a color by selectively removing wavelengths from ambient light, …

For nearly a decade, cosmologists have wrestled with a nagging mismatch called the Hubble tension. When astronomers measure the expansion of space in the nearby universe, they find a noticeably faster rate than calculations based on the early cosmos predict. A new analysis presented this week at the Royal Astronomical Society’s National Astronomy Meeting (NAM 2025) proposes an eye-catching fix. …

A radar station on Hainan Island in China has recently made an extraordinary discovery—plasma bubbles in Earth’s ionosphere, located over the Pyramids of Giza, Egypt. This remarkable event marks a breakthrough in global space weather monitoring and reveals the increasing potential for long-range ionospheric tracking. In an age where satellite communications and navigation systems are vital to everyday life, such …

According to a study, eight Pacific sleeper sharks (Somniosus pacificus) appeared during an experiment in the South China Sea, marking the first known occurrence of the species in this region. The sharks were drawn to a cow carcass dropped 1,629 meters (5,344 feet) deep into the sea as part of a study on the processes that unfold when large animals …
