    Depression may start with an energy problem in brain cells
    12/03/26 12:09:13
    Researchers have discovered a surprising change in how cells produce energy in people with depression. Brain and blood cells in young adults with major depressive disorder produced more energy molecules at rest but had trouble increasing energy production when needed. Scientists believe this imbalance may contribute to symptoms such as fatigue and low motivation. The finding could help pave the way for earlier diagnosis and more personalized treatments.
    A surprising blood protein pattern may reveal Alzheimer’s
    12/03/26 12:00:56
    A new study suggests Alzheimer’s disease may be detectable through subtle shape changes in proteins found in the blood. Researchers discovered that structural differences in three blood proteins closely track the progression of the disease. By analyzing these changes in more than 500 people, the team was able to distinguish healthy individuals from those with mild cognitive impairment or Alzheimer’s with impressive accuracy. The approach could help move diagnosis and treatment to earlier stages.
    Chickpeas could become the first food grown on the Moon
    12/03/26 11:56:39
    Scientists have grown chickpeas in simulated moon soil, offering a promising step toward farming on the lunar surface. Researchers mixed moon-like regolith with worm-produced compost and helpful fungi that protect plants from toxic metals. The combination allowed chickpeas to grow and produce a harvest in soil that normally cannot support plant life. Scientists now need to confirm the crops are safe and nutritious for astronauts.
    A “ghost” great white shark just reignited a Mediterranean mystery
    12/03/26 02:34:59
    A rare encounter with a juvenile great white shark caught by fishermen in April 2023 has reignited scientific interest in the mysterious population of these apex predators in the Mediterranean Sea. By reviewing records spanning more than 160 years, researchers found that great whites still appear sporadically in Spanish Mediterranean waters, suggesting the population—though elusive and declining—has not vanished. The discovery of a young shark raises an intriguing possibility: these legendary predators may still be reproducing in the region.
    400 million-year-old fish fossils reveal how life began moving onto land
    12/03/26 06:14:08
    Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates that eventually moved onto land. By reanalyzing mysterious fossils from Australia’s famed Gogo Formation and studying a newly reconstructed 410-million-year-old lungfish skull from China, researchers are revealing how these primitive creatures evolved.
