[ad_1] Quote of the day by Richard Feynman (Image: Wikipedia) Not knowing the answer to a question can often feel like a weakness. In school, at work and even in everyday conversations, people may feel pressure to appear knowledgeable and confident, even when they are uncertain. American physicist Richard Feynman viewed uncertainty very differently. Known…

In 2007, ESA exposed 3,000 tardigrades to space vacuum and solar UV radiation in low Earth orbit; 68% revived when the microscopic animals were rehydrated |

[ad_1] In September 2007, the European Space Agency launched roughly 3,000 tardigrades into low Earth orbit aboard the Biopan-6 platform on the FOTON-M3 mission. Known as water bears, these microscopic animals were dried into a dormant state before being exposed directly to the vacuum of space, alongside doses of solar and cosmic radiation, for ten…

In 1999, scientists dropped 45 tons of wollastonite over a 29-acre New Hampshire watershed to replace calcium lost to acid rain; by 2013, it was exporting 30 times more inorganic nitrogen than nearby watersheds

[ad_1] In 1999, scientists dropped 45 tons of wollastonite over a 29-acre New Hampshire watershed A large-scale effort to restore an American forest damaged by acid rain had an unexpected environmental effect when added nutrients caused a huge increase in nitrogen flowing into nearby streams. In October and November 1999, researchers spread about 45 short…

philip fearnsides research has calculated the costs of losing the amazon on account of deforestation

He began studying the Amazon in the 1970s; 50 years later, Philip Fearnside’s research has calculated the costs of losing the Amazon on account of deforestation, dams and highways

[ad_1] Philip Fearnside’s research has calculated the costs of losing the Amazon on account of deforestation, dams and highways The Amazon rainforest has been described in terms of its enormous size, biodiversity and importance to the global climate. But for Philip Fearnside, understanding the forest has also meant asking a more practical question: what does…

[ad_1] Representative Image of fluorescent scorpions glowing across a desert landscape after dark (AI-generated image) In 1945, an Arizona State University professor began wandering the desert at night, hunting scorpions that glowed under his black light, and few people around him understood why. That professor, Herbert L Stahnke, was already the nation’s leading authority on…

Scientists covered an Amazon rainforest plot with 6,000 panels to block half its rain; large trees died and biomass fell by a third |

[ad_1] Deep in the Caxiuanã National Forest in northern Brazil, a patch of rainforest the size of a football pitch tells the story of what a drier Amazon might look like. Since 2002, scientists have suspended nearly 6,000 transparent plastic panels above one hectare of pristine forest, diverting roughly half the rainfall away from the…

In 2001, scientists began adding 5 to 6 nanograms per litre of synthetic estrogen to an Ontario lake; after 2 seasons its minnow population collapsed

S Bhinder1 week ago04 mins

[ad_1] Representative Image (AI-generated) A tiny concentration of a synthetic hormone was enough to trigger a dramatic ecological change in a remote Ontario lake. In 2001, scientists began adding the synthetic estrogen 17α-ethynylestradiol (EE2) to Lake 260 in northwestern Ontario, maintaining concentrations of about 5 to 6 nanograms per litre. The experiment continued for seven…
