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 for…
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 days…
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 tons…

But for 13-year-old Massachusetts inventor ‘Kaia Minn,’ it became the starting point for a simple idea with potentially far-reaching environmental uses. Minn has developed a ‘biodegradable…
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 it…
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 scorpions…
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 soil…
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 years,…
Since 2015, British Columbia has killed 200-300 wolves annually to help endangered caribou populations recover. Recently, the provincial government has proposed extending its decade-long wolf cull program by five more years in areas that are home to 15 declining woodland caribou herds. But according to scientists, the deforestation, not the wolves, is the main driver…
Quote of the Day by Marie Curie Marie Curie is remembered as one of the most important scientists in modern history, yet a single letter from 1895 offers a genuinely striking glimpse into her real priorities. Ahead of her marriage to Pierre Curie in July that year, someone had offered to give her a wedding…
