Genetic study seeks to prevent foodborne infection caused by Salmonella
Publicado em 20 de fevereiro de 2019
A group of researchers from the School of Agricultural and Veterinary Sciences, at the State University of São Paulo (FCAV-UNESP) in Jaboticabal, are investigating genes that are important for the survival of the bacterial species Salmonella in the intestinal tract of poultry. The goal is to prevent foodborne infections in humans.
There are more than 2,600 known serotypes of Salmonella. Some are responsible for many cases of infection in animals and humans. The presence of certain serotypes [...]

Technology developed in Brazil will be part of the International Space Station
Publicado em 19 fevereiro 2019A new version of equipment developed in Brazil - the Solar-T - will be sent to the International Space Station (ISS) to measure solar flares. It is estimated that the Sun-THz, the name given to the new photometric telescope, will be launched in 2022 on one of the missions to the ISS and will remain there to take consistent measurements. The photometric telescope works at a frequency of 0.2 to 15 THz, which can only be measured from space. In parallel, another telescope, the HATS, will be [...]ver notícia -
'Arapuca', a device developed in Brazil for international neutrino experiment, is enhanced
Publicado em 18 fevereiro 2019A critical part of one of the largest recent particle physics experiments was developed in Brazil. The Arapuca is a light detector to be installed in the Deep Underground Neutrino Experiment (DUNE) - a project that is searching to discover new properties of neutrinos, fundamental particles with very little mass that travel at close to the speed of light. The X-Arapuca is an enhanced version of the light detector developed by professors Ettore Segreto of the Gleb Wataghin Physics Institute of [...]ver notícia -
Lithium-air batteries can store energy for cars, houses and industry
Publicado em 15 fevereiro 2019Current lithium ion battery technology will probably not be able to handle the coming decades' huge demand for energy. It is estimated that by 2050, electricity will make up 50% of the world's energy mix. Today that rate is 18%. But installed capacity for renewable energy production is expected to increase fourfold. This will require batteries that are more efficient, cheaper and environmentally friendly. One of the alternatives being studied today in many parts of the world is the [...]ver notícia -
Open-science model for drug discovery expands to neurodegenerative diseases
Publicado em 15 fevereiro 2019Parkinson's disease and Amyotrophic Lateral Sclerosis are the newest frontiers for open science drug discovery, a global movement led by academic scientists in Toronto that puts knowledge sharing and medication affordability ahead of patents and profits. Medicines 4 Neurodegenerative Diseases (M4ND Pharma) will pursue promising new genetic drug targets for these intractable nervous system disorders, thanks to $1.5 million from the Krembil Foundation. It will be the world's second drug [...]ver notícia -
Animal venoms are sources in the search for new medicines
Publicado em 14 fevereiro 2019Animal venoms are the subject of study at research center based at the Butantan Institute in São Paulo. But in this case, the idea is not to find antidotes, but rather to use the properties of the venoms themselves to identify molecular targets of diseases and, armed with that knowledge, develop new compounds that can be used as medicines. The focus of the work are immuno-inflammatory diseases like osteoarthritis and rheumatoid arthritis, cancer and neurodegenerative diseases, explained Ana [...]ver notícia -
Carbon gas storage cavern is the best way to obtain clean energy from a fossil fuel
Publicado em 13 fevereiro 2019A set of technologies that is expected to have its first results four years from now is designed to resolve one of the world's greatest oil and gas exploration challenges today: carbon dioxide (CO2) and methane (CH4) emission in the atmosphere. The innovation, the result of a patent deposited in 2018, consists of injecting the CO2 and CH4 that comes from wells during oil extraction into salt caverns as a way to reduce the amount of carbon gas in the emissions. The first "pilot cavern" may be [...]ver notícia -
Diets consisting of fewer calories improve cell performance
Publicado em 12 fevereiro 2019The number of calories a person eats directly influences the performance of different cells. A group of researchers from the University of São Paulo (USP) has shown that low-calorie meals have a protective effect against some diseases. Some of these studies were presented on Day One of FAPESP Week London , taking place February 11-13, 2019. The studies were conducted under the auspices of the Center for Research on Redox Processes in Biomedicine ( Redoxome - one of the Research, Innovation [...]ver notícia -
Research explains how snakes lost their limbs
Publicado em 06 fevereiro 2019Snakes and lizards are reptiles that belong to the order Squamata. They share several traits but differ in one obvious respect: snakes do not have limbs. The two suborders diverged more than 100 million years ago. Identification of the genetic factors involved in this loss of limbs is a focus of the article "Phenotype loss is associated with widespread divergence of the gene regulatory landscape in evolution" published by Juliana Gusson Roscito and collaborators in Nature Communications [...]ver notícia -
Oversized meals have been shown to be a factor in obesity
Publicado em 29 janeiro 2019Restaurants frequently serve oversized meals, not only in the United States but also in many other countries, according to a study conducted by an international team of researchers and supported by FAPESP - São Paulo Research Foundation. Published in the British Medical Journal , the study weighed and measured the energy content of meals served by restaurants in Brazil, China, Finland, Ghana and India. The results showed that 94% of the most popular main dishes served in sit-down restaurants [...]ver notícia
