PARIS (AFP) – Researchers warned Wednesday that rising global consumption of ultra-processed foods (UPFs) poses a major threat to health, calling for countries to subject some products made by huge food companies to marketing restrictions and taxes. The international team of researchers also pushed back against criticism of their work on UPFs, saying efforts to “manufacture scientific doubt” on the subject were similar to tactics used by the tobacco industry. There has [...]

Microplastics have been found throughout the human body -- including inside lungs, blood and brains -- and while it is not yet clear how harmful they are to our health, some researchers are sounding the alarm. These tiny pieces of plastic have been detected almost everywhere on Earth, from the deepest oceans to the highest mountains, as well as in the air, water, soil and food chain. Every day humans ingest, inhale or otherwise come in contact with microplastics, which are less than five [...]

Paris (AFP) – Wildfires made more frequent and intense by climate change released significant quantities of CO2 into the air in 2023-2024, said a first-of-its-kind annual study published Wednesday. Fires in natural areas caused 8.6 billion tonnes of CO2 emissions worldwide between March 2023 and February 2024 -- 16 percent above average. Only a relatively calm fires season in the African savannah prevented the 2023-2024 season from breaking a fresh record for CO2 emissions at the [...]

Río de Janeiro (AFP) – "Atención, tapir en perímetro próximo en la vía". Un proyecto de aplicación para conductores aspira a reducir por medio de la tecnología de Inteligencia Artificial (IA) los atropellamientos de fauna silvestre en Brasil, la principal amenaza para varias especies vulnerables. En Brasil, 475 millones de animales mueren cada año aplastados o embestidos en carreteras, según cálculos [...]

In Brazil, where about 16 wild animals become roadkill every second, a computer scientist has come up with a futuristic solution to this everyday problem: using AI to alert drivers to their presence. Direct strikes on the vast South American country's extensive road network are the top threat to numerous species, forced to live in ever-closer proximity with humans. According to the Brazilian Center for Road Ecology (CBEE), some 475 million vertebrate animals die on the road every year [...]

Las emisiones de dióxido de carbono de la Amazonía se dispararon en 2019 y 2020 debido a que durante el mandato del expresidente brasileño Jair Bolsonaro disminuyó la vigilancia ambiental en esa región cada vez más frágil, informaron investigadores el miércoles.

The Amazon rainforest's carbon emissions doubled in 2019 and 2020, as a decline in environmental policing under Brazilian ex-president Jair Bolsonaro led to a surge in destruction of the increasingly fragile region, researchers reported Wednesday. The world's biggest rainforest is a vital buffer against climate change, but studies show it has started emitting more carbon than it absorbs, pushed to a dangerous "tipping point" by deforestation and fires -- mainly for cattle [...]

Con una inversión de 10 millones de dólares, la planta de podría estar en funcionamiento en el primer semestre de 2024, con una producción de hidrógeno de 5kg/hora. El Gobierno de Sao Paulo anunció este jueves la construcción de una planta pionera en la producción de hidrógeno renovable a partir de etanol junto con empresas de energía y transporte e investigadores de la Universidad de Sao Paulo (USP), cuyo campus [...]

Sao Paulo acogerá en 2023 el primer Instituto Pasteur de Brasil, con el objetivo de trabajar para prevenir futuras pandemias, entre otras investigaciones, acordaron este viernes el centro científico y autoridades brasileñas. Dirigentes del laboratorio francés y del Estado brasileño de Sao Paulo firmaron en París la creación de este nuevo Instituto Pasteur, que retomará el trabajo de una plataforma de cooperación ya existente con [...]
