Supply chains should make the world better, not worse – it’s time for a rethink
Publicado em 14 de agosto de 2024
Every product or service that you consume is part of a supply chain. Supply chains include an array of activities connecting mining or harvesting, processing, manufacturing, logistics, marketing, retail, consumption, and waste management. Even quite simple products or services can have complex supply chains that span the globe.
Each of these activities along the supply chain will have an impact, socially and environmentally. Some are positive, such as job creation and training opportunities. [...]

Wildfires caused major CO2 emissions last year: annual study
Publicado em 13 agosto 2024Paris (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 [...]Space Daily (Austrália) -

Dopaminergic Meds Boost Sleep in Parkinson's Patients
Publicado em 13 agosto 2024A study involving 22 Parkinson's disease (PD) patients has shown that use of the dopaminergic drug levodopa improves sleep quality. When the patients took the drug, the number of times they woke up during the night fell 25% and the amount of time they remained awake fell 30% on average. The investigation was conducted with FAPESP's support by researchers at São Paulo State University (UNESP) in Brazil, and the University of Grenoble Alpes (UGA) in France. An [...]Mirage News (Austrália) -
Climate Change Boosts Odds of Unprecedented 2023-24 Wildfires
Publicado em 13 agosto 2024Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the first edition of a new systematic annual review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of [...]Mirage News (Austrália) -
Climate change is supercharging the world’s wildfires
Publicado em 13 agosto 2024Many Australians may look back on the 2019-20 Black Summer bushfires that tore through 8.1 million hectares in southeast Australia as a one-off, a singular disaster almost incomprehensible in its scale. But what if our warming world means that wildfires like those four years ago are no longer exceptional? A new global assessment of fire on Earth aims to assess the impact of wildfires – explaining their causes, our ability to predict them and their likelihood under continued climate [...]Pursuit: All articles (Austrália) -
Optical device forgoes lenses for better detection of tainted water
Publicado em 12 agosto 2024It's ironic that in places where drinking water needs to be checked for microbes the most, labs that can perform the analysis are least likely to be present. A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a Petri dish for 12 to 48 hours. Not only does this process take a long time, but it has to be performed by trained personnel in [...]New Atlas (Austrália) -
Lensless fluorescence detection system provides highly sensitive water quality assessment
Publicado em 09 agosto 2024Researchers have shown that a fluorescence detection system that doesn't contain any lenses can provide highly sensitive detection of deadly microorganisms in drinking water. With further development, the new approach could provide a low-cost and easy-to-use way to monitor water quality in resource-limited settings such as developing countries or areas affected by disasters. It could also be useful when water safety results are needed quickly, such as for swimming events, a concern [...]News Medical (Austrália) -
Peer-Certified Organic Farms Show Greater Product Diversity
Publicado em 09 agosto 2024In Brazil, a study compared two systems of organic product certification implemented in São Paulo state. One system involves conventional certification by auditors accredited by the Ministry of Agriculture and the National Institute of Metrology, Quality and Technology (INMETRO). The other is peer-to-peer certification. The study, reported in an article published in the journal Organic Agriculture, suggests that peer-to-peer certification adds the virtue of [...]Mirage News (Austrália) -
