The study was conducted in Brazil and mapped the genes that are activated when mice resistant to Leishmania are infected. Molecules involved in the signaling pathway responsible for combating the parasite can serve as biomarkers. In an article published in Scientific Reports, researchers affiliated with the University of São Paulo (USP) in Brazil describe experiments performed with mice that show how genetic factors can determine whether an individual is susceptible or resistant to [...]

Model developed by Brazilian researchers shows chaotic phase that placed objects in current orbits beginning within first 100 million years after formation of giant planets The hypothesis that the Solar System was born from a gigantic cloud of gas and dust was first floated in the second half of the eighteenth century. It was proposed by German philosopher Immanuel Kant and developed by French mathematician Pierre-Simon de Laplace. It is now a consensus among astronomers. Thanks to the [...]

The hypothesis that the Solar System was born from a gigantic cloud of gas and dust was first floated in the second half of the eighteenth century. It was proposed by German philosopher Immanuel Kant and developed by French mathematician Pierre-Simon de Laplace. It is now a consensus among astronomers. Thanks to the enormous amount of observational data, theoretical input and computational resources now available, it has been continually refined, but this is not a linear process. Nor is it [...]

Flowers and fruits emit a colorless and sweet-smelling gas, known as ethylene, as they bloom and ripen. To test the new sensor’s capabilities, the researchers deposited the carbon nanotubes and other sensor components onto a glass slide. They then used it to monitor ethylene production in two types of flowers—red carnations and purple lisianthus. Image Credit: Stock imagery edited by MIT News. Chemists at Massachusetts Institute of Technology (MIT) have developed a miniature [...]

To control flowering and fruit ripening, plants release the gaseous hormone ethylene. Environmental conditions, including drought, salinity and pathogens, can also cause levels of the hormone to fluctuate. Therefore, monitoring ethylene’s release in real time could provide a farmer with important information about a plant’s development and health. Now, researchers reporting in ACS Central Science have developed an easy-to-use, robust sensor that can do just that. Because of the key [...]

Monitoring the plant hormone ethylene could reveal when fruits and vegetables are about to spoil. CAMBRIDGE, MA — As flowers bloom and fruits ripen, they emit a colorless, sweet-smelling gas called ethylene. MIT chemists have now created a tiny sensor that can detect this gas in concentrations as low as 15 parts per billion, which they believe could be useful in preventing food spoilage. The sensor, which is made from semiconducting cylinders called carbon nanotubes, could be used to [...]

Research conducted in recent decades has shown how the destruction of forests brings about a decline in species diversity. A research group in Brazil led by scientists at São Paulo State University (UNESP) has now reported the findings of an investigation into how landscape changes caused by deforestation, habitat loss and fragmentation lead directly to the loss not only of species, but also of their ecological interactions. The report is published in Biotropica and features on the [...]
