Incendiamoeba cascadensis can reproduce at 145°F, setting a heat-tolerance record for complex life. Image: NPR/Felix Mikus. Scientists have discovered a previously unknown amoeba in the geothermal streams of California’s Lassen Volcanic National Park that can reproduce at temperatures reaching 145°F (63°C). Named Incendiamoeba cascadensis, the organism has set a new heat-tolerance record for known eukaryotic…

Maquet, Observatoire de Paris In 2013, astronomers discovered two narrow rings around Chariklo, a 250-kilometre-wide minor planet orbiting between Saturn and Uranus, marking the first time rings had been found around such a small body. Nine years later, the James Webb Space Telescope observed the same system during a rare stellar occultation and…

Representative Image (AI-generated) What started as piles of concrete blocks on the seafloor off Prince Edward Island soon became a magnet for marine life. Researchers began installing the artificial oyster reefs in 2021 to test whether they could provide some of the ecological functions lost from areas where eelgrass no longer grew. Within two years,…

Among the species benefiting from the restoration are yellow-eye mullet. A major effort to remove invasive rice grass from Tasmania’s Duck Bay is showing major signs of recovery, with native vegetation returning and the number of fish species rising from five to 11. The changes came within just two to three years of the weed…

Phillip Island’s little penguins once faced a crisis that threatened to erase much of their presence from the island. By the 1980s, nine of its 10 penguin colonies had disappeared, while the final colony on the Summerland Peninsula was also under pressure from introduced predators, habitat loss and human activity. According to Phillip Island Nature…

At 13, Kelvin Doe was searching through piles of discarded materials in Freetown for things most people would have left behind. Acid, soda, scrap metal and broken components became part of a series of homemade experiments that gradually moved from a battery to a generator and then a transmitter. The teenager had no conventional electronics…

Turuépano National Park. Image Credit: Wikipedia Guyana’s mangrove restoration programme planted more than 500,000 seedlings along 8 km of coastline, and a study published in Restoration Ecology has found that restored forests aged between 5 and 11 years were already supporting fish communities similar to those in natural mangroves. Researchers compared restored and naturally regenerated…

The eDNA autosampler to monitor for invasive aquatic species. Image Credit: CPR/USGS The Colorado River is getting a new line of defence against invasive species, with a $29,595 environmental DNA autosampler being used to search for traces of unwanted fish and other aquatic threats. Instead of waiting to catch an invasive animal, the machine collects…
