A spectacular fossil site in Canada contains 567-million-year-old creatures that may represent some of the earliest animals to move, reproduce sexually, and develop recognizable body plans。 The discovery pushes key evolutionary milestones back by up to 10 million years and suggests complex animal life may have first flourished in the deep ocean
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes。 The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space。 By studying these laboratory samples, scientists can explore how organic chemistry unfo
A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics。 Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of
Europa’s hidden ocean has made the icy moon one of the solar system’s most promising places to search for habitable conditions。 Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future spacecraft could more easily study。 New simulations suggest that journey is unlikely because turbulent
An exceptionally preserved snake fossil from Brazil reveals that early snakes were far more diverse than scientists once thought。 Detailed brain reconstructions show that Tametara mirim was adapted for burrowing, while another ancient snake was suited to life above ground。 Other fossils point to marine lifestyles as well
Songbirds appear to have evolved through rare explosions of change separated by long periods of slower development。 Many of those bursts lined up with major climate shifts, suggesting that environmental upheaval can reshape life in powerful ways
A long-term brain study found that common risks such as smoking, high blood pressure, heart disease, and high blood lipids were strongly linked to damage associated with vascular dementia。 The findings suggest that healthier lifestyle choices could help delay dementia by reducing several harmful brain changes at once
Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s。 In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan。 Reducing EPS8 activity prevented thes

A massive crocodilian capable of attacking dinosaurs has been brought back to life as the first scientifically accurate mounted skeleton of Deinosuchus schwimmeri。 The 31-foot replica at Georgia’s Tellus Science Museum was built from detailed fossil scans and more than 40 years of research by paleontologist Dr。 David Schwimmer, for whom the species
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems。 Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atria
