Scientists lay out revolutionary method to warm Mars      (via sciencedaily.com)     Original source 

Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.

Fishing is causing frightened fish to flee when they should flirt      (via sciencedaily.com)     Original source 

Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.

Social rank may determine if animals live fast, die young      (via sciencedaily.com)     Original source 

Social rank may determine whether animals prioritize immediate fitness over long-term health, according to a study. Researchers studied macaques on a Thai island and found that the animals' unusual habit of washing their food is in fact based on social rank. Dominant monkeys quickly brush their food on their fur before eating it, along with mouthfuls of tooth-degrading sand, while lower-ranked monkeys obsessively wash their food in the surf. Citing the disposable soma hypothesis, the researchers suggest that high-ranking macaques are looking to quickly consume energy to mate and fend off challengers. But food-washing monkeys may be preserving their long-term health to produce more offspring over time. The findings could shed light on how the wear observed in the fossilized teeth of early humans relates to social structure.

South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows      (via sciencedaily.com)     Original source 

Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.

Soft gold enables connections between nerves and electronics      (via sciencedaily.com)     Original source 

Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Carvings at ancient monument may be world's oldest calendars      (via sciencedaily.com)     Original source 

Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.

Groundwater reserves in southwestern Europe more stable overall than previously thought      (via sciencedaily.com)     Original source 

Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.

Antarctic-wide survey of plant life to aid conservation efforts      (via sciencedaily.com)     Original source 

The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis      (via sciencedaily.com)     Original source 

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.

Hydraulic lift technology may have helped build Egypt's iconic Pyramid of Djoser      (via sciencedaily.com)     Original source 

The Pyramid of Djoser, the oldest of Egypt's iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to researchers. A new study suggests that water may have been able to flow into two shafts located inside the pyramid itself, where that water could have been used to help raise and lower a float used to carry the building stones.

Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
