A newly described 57-centimeter microraptorine dinosaur, Norellraptor barsboldi, from Liaoning province, China, provides evidence that flight evolved independently in birds and non-avian dinosaurs. The fossil, dated to 145–100 million years ago, shares 30% of flight-related adaptations with birds but in a different sequence, supporting convergent evolution over a shared ancestral flight apparatus.
Steven Lawyer, an Iowa attorney, constructed a custom life-support capsule named the 'Bebosphere' to allow his white-winged parakeet, Bebe, to snorkel in the Bahamas. The device, built from a clear food container, a paintball air tank, and safety valves, kept the bird submerged for 15 minutes at a depth of one meter. The incident sparked viral debate regarding animal consent and AI authenticity, though Lawyer maintains the bird showed no stress.
Colossal Biosciences announced it hatched 26 chicks from a 3D-printed artificial eggshell as part of its de-extinction efforts to resurrect the extinct 12-foot moa. The system uses a membrane-enabled shell but omits other egg components, prompting scientists to note it is not a true artificial egg and that reviving the moa remains speculative. If progress continues, challenges include validating DNA, scaling to larger eggs, ecological fit, and ethical considerations, though the company argues the platform could aid endangered birds and embryo rescue.
Colossal Biosciences hatched 26 healthy chicks from a 3D-printed titanium artificial egg with a silicone membrane, proving a shell-free avian development system that could aid conservation and pave the way for reviving extinct birds like the moa and dodo; they aim for moa revival in New Zealand in the early- to mid-2030s, in collaboration with Ngāi Tahu and Peter Jackson, with future tests on larger eggs (emu/ostrich) to scale the technology.
Hummingbirds are able to fly through spaces smaller than their wingspan due to their unique wing morphology and specialized flight capabilities. Researchers have found that hummingbirds can rotate their wings in a figure-eight pattern, allowing them to generate lift on both the forward and backward strokes. This remarkable ability enables them to maneuver through intricate environments with precision and agility, showcasing the fascinating aerodynamics and adaptability of these tiny avian creatures.
