Scientists marked this coral reef as dead in the 1960s; underwater drones found it alive...
After being presumed extinct for sixty years, a remarkable coral reef off West Africa has been rediscovered, thriving with an array of fish and coral species. This vibrant mesophotic coral ecosystem thrives in low-light environments beneath the ocean's surface. Researchers speculate that similar hidden reefs could exist along the West African coastline, providing valuable insights into the evolutionary history of the region's marine life and past environmental changes.
Some species of mosquitoes in the UK spread avian malaria
In a landmark study, researchers have pinpointed certain mosquito species that spread avian malaria in the UK. Among twelve species analyzed, nine were found to harbor traces of this bird disease. Notably, the Ochlerotatus detritus mosquito is suspected to transmit Plasmodium vaughani to blackbirds, with additional species identified as potential carriers for parasites that threaten various native birds.
Hunters carried trout past waterfalls into fishless Norwegian mountain lakes 7,000 years ago
In a remarkable feat 7,000 years ago, ancient hunter-gatherers transformed Norwegian mountain lakes by introducing brown trout. Archaeologists discovered remnants of intricate fish traps from 5000 BC, highlighting how these early communities intentionally manipulated their ecosystems for sustainable food resources. They even transported live fish through rugged landscapes, paving the way for the fisheries we know today, where anglers still catch their ancient descendants.
Scientists warn AI-edited bird photos could create fake sightings and threaten biodiversity research
Scientists turned plastic waste into clean hydrogen fuel without expensive sorting and it could revolutionise recycling forever
New research offers a method to convert mixed plastic waste into clean hydrogen fuel. The innovative technique allows for the processing of various plastic types together without sorting. This breakthrough could turn discarded plastic into a valuable energy source for homes. The development supports a circular economy and reduces environmental pollution effectively.
Meet Laika: The Moscow stray dog who became the first animal to orbit Earth in 1957, but was never meant to come home
Laika, a stray dog, became the first living creature in Earth orbit aboard Sputnik 2. The spacecraft was built in haste and lacked any return system for the animal. Soviet officials initially claimed Laika survived for days before a peaceful death. However, a scientist later revealed she died within hours due to system failure. This mission accelerated American efforts to develop a human space program.
World’s largest oceanic plateau still hides ancient magma pathways after 100 million years
Scientists uncovered ancient magma pathways beneath the Ontong Java Plateau. These hidden dike swarms reveal how enormous magma volumes traveled through the lithosphere. Seismic waves passing through the plateau showed unusual behavior. This behavior indicated a hybrid internal structure with vertical dike-like formations. These preserved dike swarms permanently reshaped the surrounding rocks over geological time.
Scientists find toxins from Florida's toxic algae blooms travel through air, raise risk of ALS
Recent research reveals the presence of cyanobacterial toxins in the air of Southwest Florida, matching those found in dolphins displaying Alzheimer's characteristics. This airborne contamination indicates that inhabitants may be exposed to lower concentrations of these toxins, which are believed to heighten the chances of ALS and various ailments. Unlike food-related toxins, mitigating exposure through breath poses a significant and complex challenge.
Biohacker Bryan Johnson claims ice packs boost male fertility: Does science agree?
Bryan Johnson, a longevity influencer, claims that icing his testicles greatly increases his sperm count. His unique approach has inspired several Redditors to experiment with this method for improving fertility. Although some research hints at the benefits of mild scrotal cooling for male fertility, experts caution that there is insufficient evidence to suggest significant improvements in testosterone or overall sperm production.
Debris of asteroid shattered 800 million yrs ago may have bombarded Earth for 150 million yrs
A new study suggests that a giant asteroid breakup in the main asteroid belt about 800 million years ago may have triggered a long period of impacts across Earth, the Moon and Mars. Researchers linked the event to the Eulalia asteroid family and say it could explain ancient lunar craters. While the impacts coincided with major climate and biological changes on Earth, the study does not prove they caused them.
Big Bear Eagles need $10 million to protect their habitat before July 31
Thousands of people around the world are watching bald eagles Jackie and Shadow raise their two eaglets through a live nest camera in California's Big Bear Valley. As the chicks continue to grow, conservationists are also racing to raise $10 million to protect the surrounding habitat from development, highlighting the importance of preserving the forests and open spaces the eagles need to survive.
