In 2019, scientists shook earthworms and found waves oscillating at half the driving frequency
Scientists observed earthworms developing body waves at half driving frequency. Their flexible, water-filled bodies and elastic skin supported these unusual oscillations. This phenomenon resembled waves found in vibrating liquid drops and phantom models. Researchers believe this could help probe biological processes like nerve impulse propagation. The findings suggest nonlinear wave excitation has potential beyond earthworm studies.
Scientists fitted GPS collars to 17 lions and 14 hyenas expecting hyenas to follow lions
A groundbreaking study suggests that it's the male lions that approach spotted hyenas, contrary to the belief that hyenas seek out lion remains for food. In fact, spotted hyenas are known to back away from lions, prioritizing their safety. This finding highlights the importance of spatial avoidance in hyena behavior, emphasizing their adaptive strategies to circumvent confrontations with such powerful hunters.
Is AI going to 'kill everyone' in ten years?
Hopefully, whatever version of doomsday the AI world is worried about waits until after Avengers: Doomsday, because after all the multiverse nonsense and speculation about how Robert Downey Jr is going to return to the MCU as Doctor Doom, one really wants to watch Kevin Feige explain that before artificial intelligence kills everyone.
Belize Reef Restoration Effort: Lisa Carne revives storm-hit corals; project outplants 100,000 fragments
In 2001, Hurricane Iris wreaked havoc on Belize's coral reefs, sparking an innovative restoration effort. Marine biologist Lisa Carne took the lead in replanting coral fragments, which were often neglected. Through her organization, Fragments of Hope, more than 100,000 corals have been successfully restored, resulting in a remarkable boost in coral coverage and marine biodiversity.
Snake grows a fake spider on its tail to lure birds; scans reveal surprisingly normal bones inside
Researchers utilized XCT scanning technology to investigate the unique tail of a viper. The imaging uncovered the presence of standard viper vertebrae within the tail's unusual form. This finding underscores the discrepancies that can exist between external appearance and internal skeletal makeup. Fossilized remains alone may not capture the true look of an organism, while museum specimens remain crucial for advancing our understanding through innovative methods.
South China Sea methane leak formed a 1km plume; worms and bacteria built a ‘worm bed’ in 2 years
A South China Sea drilling incident caused a significant methane leak in 2018. Ocean scientists observed an ecosystem rapidly responding to the underwater gas release. Bacteria and worms quickly formed a methane-munching 'worm bed' within two years. This new biofilter degraded methane effectively, reducing plume height significantly. However, this rapid ecosystem development caused a notable decrease in original microbial diversity.
In 1982, Israel released 28 wild donkeys; 44 years later, they created a desert oasis
In an effort to rejuvenate the parched landscape of Israel's Ramon Crater, wild donkeys were brought back into the ecosystem. These resilient animals played a crucial role by creating waterholes, which became essential for desert wildlife. Additionally, their droppings helped spread acacia seeds, promoting the growth of trees. Their natural movements resulted in water-retaining depressions, significantly transforming the area's ecology into a thriving environment that has caught global attention.
Dam Removal Restores Creek: Buckhorn Creek flows freely again; volunteers plant trees
After more than a century, the Buckhorn Creek dam has been dismantled, reviving its original flow for the first time in 125 years. A modern ninety-foot bridge now crosses the creek, enhancing access for trail enthusiasts. This ecological restoration significantly improves aquatic habitats, particularly supporting brook trout populations. Additionally, volunteers will introduce native plants along the banks to help stabilize the soil.
Meet Vivian Liu, the 17-year-old who turned origami into a kindness movement across 50 nations
Vivian Liu has turned origami into a powerful global movement for kindness. Thousands of passionate young volunteers are making beautiful paper art to support those facing hardships. With more than 300 chapters in 50 countries, Origami For Good empowers youth with leadership skills and environmental consciousness, proving that even the smallest handcrafted items can create a profound and positive impact across the globe.
