Agência FAPESP – Few countries today play a leading role in scientific advances in climate modeling. Most of these countries – the United States, for example – are in the Northern Hemisphere. Australia was the only country in the Southern Hemisphere with this capacity. However, after developing its own climate models for 30 years, the [...]Leia mais
For the first time, U.S. Geological Survey scientists have mapped long-term average evapotranspiration rates across the continental United States – a crucial tool for water managers and planners because of the huge role evapotranspiration plays in water availability.
Why are evapotranspiration rates so important to know? It’s because the amount of water available for people and [...]Leia mais
Agência FAPESP – Summer time: think vacations and trips to the beach. To determine which beaches are safe for swimming and which are polluted, environmental agencies perform hydrochemical analyses along the entire Brazilian coastline. And a study carried out at the Geosciences Institute in the Universidade de São Paulo (USP) School of Arts, Sciences and [...]Leia mais
Analysis published by the U.S. Department of Agriculture’s (USDA) Economic Research Service (ERS) in the most recent issue of the journal Science examine the relationship between public and private investments in research and development (R&D) and their importance in agricultural input industries. The Science article is drawn from a recent ERS study that provides new details on the [...]Leia mais
HOW much will Earth warm this century? The best answer to this killer question remains broad, but a study has narrowed the range of likely temperatures – and comes down on the warmer side.
As we pump more greenhouse gases into the atmosphere, temperatures rise. The consensus among climatologists is that if the amount of carbon [...]Leia mais
A group of Brazilian and British researchers began flying over Amazonia on September 12 to understand how the emissions from fires in the region are changing the local and global climate.
With the help of cutting-edge technology, scientists are collecting data on the chemical composition and physical properties of the smoke emitted. They are also verifying [...]Leia mais
MANILA — Global warming is likely to alter rainfall patterns in East Asia and the Pacific, causing more intense drought and floods in decades to come, according to a study published in Nature last month (15 August).
A team of Australian-based scientists estimated that increased greenhouse gas emissions in the atmosphere will enhance equatorial Pacific warming [...]Leia mais
Agência FAPESP – After studying the evolutionary process of diversification of a group of tube-dwelling anemones in the South Atlantic Ocean for four years, a group of researchers from Universidade de São Paulo (USP) obtained an unexpected result: the biological investigation ultimately contributed results that reinforced the geological theory that roughly 10 million years ago, [...]Leia mais
Vietnamese and Japanese researchers have investigated the spread of antibiotic-resistant salmonella isolates in retail pork and poultry meat from North Vietnamese markets.
A total of 118 Salmonella isolates were detected from 283 retail meat samples (135 pork and 148 chicken meat) purchased at retail markets in Northern Vietnam. Thirteen serovars, including Infantis, Anatum, Rissen, Reading, Emek, [...]Leia mais
A network of universities, research centres and technical institutions to provide practical sustainable development solutions has been launched by the UN.
The Sustainable Development Solutions Network (SDSN), launched last month (9 August), will work with governments, UN agencies, the private sector and civil society organisations to identify and demonstrate new approaches to sustainable development.
Poverty alleviation, social [...]Leia mais
