Scientists discovered a secret deal between a plant and beetles
A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of those fruits, yet the larvae survive by escaping into the soil. The discovery suggests that fruit drop is not punishment but a compromise that keeps the plant–insect relationship stable.
Depression may start with an energy problem in brain cells
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
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
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
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 pr
400 million-year-old fish fossils reveal how life began moving onto land
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.
A “mirror” molecule can starve cancer cells without harming healthy cells
Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, this molecule—called D-cysteine—is taken up mainly by some cancer cells through a specific transporter on their surface. Once inside, it shuts down a crucial mitochondrial enzyme that cancer cells rely on to produce energy and maintain DNA, effectively
Scientists discover a universal temperature curve that governs all life
Researchers have uncovered a universal pattern showing how temperature affects life on Earth. Across thousands of species—from microbes to reptiles—performance rises gradually with warming until an optimal temperature is reached, after which it drops sharply. Although each species has its own preferred temperature range, they all follow the same underlying curve. This surprising constraint suggests evolution may have limited room to help species cope with rapid climate warming.
Cosmic rays turned ancient sand into a geological time machine
Scientists at Curtin University have uncovered a new way to read the deep history of Earth’s landscapes using microscopic zircon crystals from ancient beach sands. These incredibly durable minerals trap traces of krypton gas created when cosmic rays strike them at Earth’s surface, effectively turning each crystal into a “cosmic clock.” By measuring that krypton, researchers can determine how long sediments lingered near the surface before burial, revealing how landscapes eroded, shifted, and sta
Scientists discover hedgehogs can hear ultrasound and it could save them from cars
Researchers have discovered that hedgehogs can hear ultrasound, a surprising ability that could help protect them from cars. Since road traffic kills large numbers of hedgehogs, scientists believe ultrasonic repellents might be used to steer them away from danger. The animals’ ears appear specially adapted for detecting high-frequency sounds. If the idea works, cars could one day emit signals that warn hedgehogs before it’s too late.
Extreme weather is hitting baby birds hard in a 60-year study
Decades of data from over 80,000 great tits reveal that extreme weather can shape the fate of baby birds. Cold snaps soon after hatching and heavy rain later in development shrink nestling body mass and reduce survival odds. But moderate warm spells can actually help chicks grow by boosting insect activity and feeding opportunities. Birds that breed earlier in the season seem better protected from these weather shocks.
A black hole and neutron star just collided in a strange oval orbit
Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the event GW200105, contradicts the long-held expectation that such pairs settle into nearly perfect circles before collision. The eccentric orbit suggests the system likely formed in a chaotic stellar environment with strong gravitational interactions.
