Study of dune dynamics will help scientists understand the topography of Mars

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Researchers at the University of Campinas conducted more than 120 experiments with dunes of up to 10 cm that interact for a few minutes, obtaining a model valid for dunes on the surface of Mars that are many miles long and take more than a thousand years to interact

How much greenhouse gas emission comes from tropical deforestation and peatland loss?

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

New research papers provide better data for tropical countries on how land conversion -- in this case, the removal of tropical forests and peatland for agriculture -- leads to increased greenhouse gas emissions.

A no-meat diet everywhere will not solve the climate crisis

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

Scientists argue Authors further argue that a singular focus on negative livestock-related environmental impacts ignores the critical but more positive role livestock play in ecosystem services, income and asset provision or insurance in low- and middle-income countries. It also overlooks more systemic questions about how animals are raised.

Drug for pulmonary hypertension may become an option against cancer

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

In experiments by Brazilian researchers with mice and tumor cell lines, the drug showed potential to combat metastasis. The scientists are planning to conduct clinical trials with patients who are on chemotherapy.

Male bats with high testosterone levels have large forearm crusts when females are fertile

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Mammalian odors are frequently sexually dimorphic, with males often exhibiting a stronger, or otherwise distinct, odor relative to females, which can be especially useful for nocturnal species with reduced use of vision. Some male bats exhibit intense odors to attract females and reproduce, presumably as a consequence of a high concentration of testosterone.

Industrial waste is reused to produce alternatives to plastic

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Researchers at São Paulo State University reused bacterial cellulose scraps usually thrown away by manufacturers of wound dressings to make strong biodegradable film for food packaging

America's crop cousins are numerous, imperiled, and more needed than ever

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

A new study in Proceedings of the National Academy of Sciences for the first time outlines how poorly protected these plants are: More than half of the 600 plants assessed in the study may be endangered in their natural habitats, while only 7% are well represented in conservation repositories such as public gene banks and botanical gardens.

High-tech fixes for the food system could have unintended consequences

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

In a new analysis published in The Lancet Planetary Health, a team of scientists examines how technologies to fix the food system can have unanticipated impacts on global development goals.
