Study shows how exercise protects pancreas in diabetics

The findings are described in a paper published in ‘The FASEB Journal’ and selected for the Research Highlights section of ‘Nature Reviews Endocrinology’

A study conducted at the University of Campinas (Unicamp) in São Paulo State, Brazil, has shown that interleukin 6 (IL-6), a substance secreted by muscles in response to physical exercise, increases the survival of the pancreatic cells that produce insulin in a type 1 diabetes model. “Besides reinforcing the importance of physical activity in the control of diabetes, the discovery paves the way to the development of drugs that simulate the action of IL-6 in the pancreas,” said Claudio Cesar Zoppi, a researcher at the Endocrine Pancreas & Metabolism Laboratory of Unicamp’s Department of Structural & Functional Biology, and one of the article’s authors.

Fire, a key element in the ecological and evolutional process of the vegetation of the Mediterranean basin

Ecosystems prone to fire, such as those of the Mediterranean, are dominated by vegetation that is adapted to fire as a result of millions of years of this association between plants and fire

Fire Ecology is the scientific discipline that studies the role of fire in organisms and ecosystems. Despite the fact that fire has a generally negative connotation, it is part of the ecosystem and there is evidence that it has occurred ever since the appearance of land plants millions of years ago in the Palaeozoic, and that it has therefore influenced their evolution. For instance, ecosystems prone to fire, such as those of the Mediterranean, are dominated by vegetation that is adapted to fire as a result of this long association.

Drivers have bad memories

A study by the University of Salamanca confirms that driving reduces the brain's efficiency in other tasks that one tries to carry out at the same time, such as memorising the details of a conversation

The Recognised Research Group (Grupo de Investigación Reconocido, GIR) on Memory and Cognition of the Universidad of Salamanca has been studying for years different processes of the human memory, in particular the frequent distortions it suffers under normal conditions. One of these lines of research, which is being carried out in collaboration with experts from the United States, has led it to analyse what occurs when a person is driving a car. Experiments show that the efficiency of remembering the information received in this situation is very low.

ALMA reveals intense magnetic field close to supermassive black hole

This new observation helps astronomers to understand the structure and formation of these massive inhabitants of the centres of galaxies, and the twin high-speed jets of plasma they frequently eject from their poles

The Atacama Large Millimeter/submillimeter Array (ALMA) has revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole. This new observation helps astronomers to understand the structure and formation of these massive inhabitants of the centres of galaxies, and the twin high-speed jets of plasma they frequently eject from their poles. The results appear in the 17 April 2015 issue of the journal Science.

The tiny transmitters Dina Dechmann places on bats cannot surpass five percent of their body mass. Unfortunately for Teague O'Mara, a Marie Curie Fellow based at the Max Plank Institute for Ornithology, STRI and the University of Konstanz no such restrictions exist for bat-tracking biologists. His gear includes a large, hand-held antenna, bulky headphones, a radio receiver hanging around his neck since his hands are full, and a sound recorder—all connected by a couple meters of cable. A GPS receiver, headlamp, compass and water complete the kit.

Over 28% of children are exposed to cigarette smoke in the family car

Research carried out by the Universidad de Beira Interior shows that Portuguese children aged nine whose parents smoke suffer five times more exposure to cigarette smoke in cars

An extensive study carried out by the Faculty of Health Sciences of the Universidad de Beira Interior of Covilhã, in collaboration with the Universidad del Miño of Braga, has found that over 28% of Portuguese children aged nine are exposed to cigarette smoke when they travel by car. Experts thus draw attention to this problem, which is particularly serious as these children are inhaling toxic substances in enclosed spaces, and recommend that measures should be taken.

The effects of climatic change on soil microorganisms are modulated by the depositing of nitrogen in the atmosphere

A team of scientists from Spain, Portugal, and the United States have carried out an experiment to demonstrate the key role of the depositing of nitrogen as a modulator of the responses of temperate woodland to climatic change

Researchers from Spain, Portugal, and the United States have found that the effects of climatic change on the functioning of soil microorganisms are modulated by the depositing of nitrogen in the atmosphere. The amount of nitrogen pollution in the atmosphere in an area will determine the response of the system to the expected changes in precipitation as a consequence of climatic change.

New strategy can help to prevent and treat sepsis in diabetics

A new strategy with the potential to treat sepsis in patients with type 1 diabetes has been proposed by researchers at the USP in a paper published in the journal 'Science Signaling'

In experiments with diabetic mice, the research group at USP’s Biomedical Science Institute (ICB) achieved a 40% reduction in mortality due to sepsis by treating the animals with a substance that inhibits the synthesis of an inflammatory mediator known as leukotriene B4 (LTB4). Similar drugs are already used to combat asthma and other allergic conditions. “Our work shows that type 1 diabetic mice present sterile inflammation that is dependent on this mediator, LTB4. This base inflammation increases the susceptibility to sepsis,” said Luciano Filgueiras, the first author of the paper. Inflammation is termed sterile when it is not due to infection.
