Ribeirão Preto completa 170 anos com um rico patrimônio histórico. O g1 preparou um roteiro com 12 locais que contam a história da cidade, desde a época dos barões do café até a chegada dos imigrantes.
Scientists in St. Petersburg have created Russia's first automated neural network system using computer vision to analyze reindeer external features for health assessment, addressing challenges in the Arctic livestock industry.
Researchers are testing a geoengineering method in Cambridge Bay, Canada, to refreeze Arctic sea ice. The Real Ice project pumps ocean water onto the ice surface, thickening it and reflecting more sunlight. While controversial, it's a research effort to explore potential solutions to climate change.
Mongolia's permafrost is rapidly thawing due to climate change, impacting local ecosystems, herder livelihoods, and releasing greenhouse gases. This transformation offers crucial insights into global permafrost dynamics and future Arctic conditions.
France and other nations rebuked the US at an Antarctic Treaty meeting for avoiding the term 'climate change', preferring specific environmental issues. The US cited a need for action-oriented discussions, but conservationists and experts criticized the stance as out of step with global consensus.
The Biodiversity Heritage Library (BHL), a digital archive of natural world literature, has made over 64 million pages freely available. Despite its crucial role in scientific research and understanding biodiversity crises, BHL faces funding cuts and may cease operations by 2027.
Over 13,000 seal pups have died on Australia's Heard Island due to H5N1 bird flu, with high mortality rates confirmed among penguins, seals, and petrels. The virus likely spread from French subantarctic islands, marking its eastward movement around the region. Australia is increasing preparedness for potential mainland incursions.
Hyundai Motor Group will implement a clean hydrogen energy system at South Korea's Antarctic research station, reducing reliance on diesel generators. The system converts surplus solar energy into hydrogen, which is then used to produce electricity via fuel cells when solar power is limited.
Antarctica's harsh environment has led to numerous unexplained deaths and disappearances over decades. From a young Chilean woman on Livingston Island to Scott's doomed expedition and accidents involving crevasses and storms, records are often fragmentary, leaving many events without clear closure.
Antarctica's west coast is experiencing a severe deficit of winter sea ice in the Bellingshausen Sea, with an area the size of France missing. This alarming trend raises concerns for penguins, marine life, and global sea levels, and may have intensified a recent heatwave on the continent.
Irish band Bleech 9:3 channels their experiences with addiction and recovery into raw, autofictional music. Frontman Barry Quinlan and guitarist Sam Duffy, both in Alcoholics Anonymous, share their journey from personal struggles to a burgeoning music career with major label interest and festival dates.
A UK-funded geoengineering experiment in Cambridge Bay, Canada, is pumping ocean water onto sea ice to thicken it and combat rapid melting due to climate change. The "Real Ice" project aims to test the feasibility and safety of refreezing Arctic ice, with potential benefits for local communities and global climate.
Scientists detected iron-60, a radioactive isotope from ancient supernovae, in Antarctic ice up to 80,000 years old. This suggests Earth is still being showered by debris from stellar explosions millions of years ago, indicating our planet is traveling through a cloud of cosmic dust.
Russian scientists have created an AI algorithm that predicts extreme weather events in the Arctic with five times higher resolution than global climate models. The AI, trained on ERA5 data, can forecast wind fields and wave heights in the Barents Sea with remarkable speed and accuracy, aiding maritime safety and wind power applications.
Volunteers from the Clean Arctic project and Arktikugol Trust Company have cleared 30 tons of scrap metal from Piramida, a former Soviet mining town on the Spitsbergen archipelago. The collected waste will be transported for processing, highlighting Russia's commitment to environmental responsibility in the region.
An area of Antarctica comparable to France has failed to form winter sea ice in the Bellingshausen Sea, alarming scientists. This unusual event, coinciding with a heatwave, raises concerns for penguins, marine ecosystems, and sea-level rise.
Melting icebergs are depositing vast amounts of rock onto the Arctic seafloor, creating new hard surfaces for marine life like sponges and corals. This unexpected consequence of climate change is reshaping deep-sea ecosystems in the rapidly warming Arctic.

Conservationists propose a protected area for Ernest Shackleton's Endurance wreck in the Weddell Sea, fearing climate change and increased shipping may damage the historic site. The proposal passed a key meeting but awaits final approval from CCAMLR.
A report has warned that old chemicals found inside historic huts belonging to Ernest Shackleton and Robert Falcon Scott in Antarctica could pose potential explosive hazards. The chemicals, possibly picric acid crystals, solution, and peroxide crystals, require careful handling and disposal.
A report has warned that old chemicals found inside historic huts belonging to explorers Ernest Shackleton and Robert Falcon Scott in Antarctica could pose potential explosive hazards. The chemicals, possibly picric acid and peroxide crystals, require careful handling and disposal, with experts noting they can detonate under specific conditions like heat or shock.
Scientists express concern over the Bellingshausen Sea in West Antarctica, which is missing a 'France-sized' chunk of winter sea ice, approximately 650,000 sq km. This area, typically ice-covered in June, remains largely ice-free, raising fears it may not reform.
Antarctica's west coast is experiencing a severe deficit of winter sea ice, with an area the size of France missing in the Bellingshausen Sea. This alarming loss raises concerns for penguins, marine life, and global sea levels, and may have intensified a recent heatwave on the continent.
Russia's Ambassador to Canada, Oleg Stepanov, warned that unilateral military build-ups in the Arctic will prompt retaliatory measures from Russia, emphasizing the region's importance for peace, development, and cooperation.
