A turquoise tint for the Black Sea caused by phytoplankton
The Black Sea sits at the boundary between Europe and Asia and connects to the Mediterranean Sea via a chain of waterways. Its surface often appears dark, but each spring and summer it transforms into a striking expanse of swirling turquoise. The OCI (Ocean Color Instrument) on
A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional fabric of the universe.

Ancient geology helps explain why Australia holds some of world's richest gold
Gold has long held a special place in Australia's history, shaping the nation's economic fortunes and driving waves of migration since the 1850s gold rushes. Today, Australia stands as one of the world's largest gold producers, with the precious metal a key driver of both
Miniature satellite tags reveal diving behavior of juvenile sea turtles
Until recently, researchers were unable to conduct satellite-tracking studies on juvenile turtles because of their small body sizes and immediate dispersal into the ocean, leaving this period of their lives enigmatic and often referred to as the "lost years." A study titled

Osteopenia is silently weakening bones in millions of people
Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and inactivity can all contribute to
Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor of stride length. A similar reduction in step length

Did gravitational tides cause Earth's extinctions?
Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on Earth suffered multiple extinctions, but got up, dusted
Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's internal heat flow, structure and magnetic field.
