South American marsupials discovered to reach new heights

For the first time, scientists catch on camera a tiny marsupial climbing higher than previously thought in the forest canopy

In the Andean forests along the border of Chile and Argentina, there have long been speculations that the mouse-sized marsupial monito del monte (Dromiciops gliroides) climbs to lofty heights in the trees. Yet, due to the lack of knowledge about the region's biodiversity in the forest canopies, no previous records exist documenting such arboreal habits for this creature.

Mother bats may nudge pups to grow up

Bat researchers observed a new behavior. Mothers push pups away with their forearms, perhaps encouraging them to go explore the world on their own

Baby birds learn to fly. Baby mammals switch from milk to solid food. Baby bats, as winged mammals, do both at the same time during their transition from infants to flying juveniles. According to a new report from researchers STRI who studied Peters’ tent-making bats ('Uroderma bilobatum'), mothers prod their young with their forearms, perhaps encouraging them to fledge and wean.

Galaxy-scale fountain seen in full glory

ALMA observations of Abell. 2597 show the first clear and compelling evidence for the simultaneous infalling and outflow of gas driven by a supermassive black hole

A billion light-years from Earth lies one of the Universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597. At the core of the central galaxy, a supermassive black hole is powering the cosmic equivalent of a monumental fountain, drawing in vast stores of cold molecular gas and spraying them back out again in an ongoing cycle.

Pioneering biologists create a new crop through genome editing

From wild plant to crop: CRISPR-Cas9 revolutionizes breeding, New tomato contains more valuable antioxidants

Crops such as wheat and maize have undergone a breeding process lasting thousands of years, in the course of which mankind has gradually modified the properties of the wild plants in order to adapt them to his needs. One motive was, and still is, higher yields. One "side effect" of this breeding has been a reduction in genetic diversity and the loss of useful properties. This is shown, among others, by an increased susceptibility to diseases, a lack of taste or a reduced vitamin and nutrient content in modern varieties. Now, for the first time, researchers from Brazil, the USA and Germany have created a new crop from a wild plant within a single generation using CRISPR-Cas9, a modern genome editing process. Starting with a "wild tomato" they have, at the same time, introduced a variety of crop features without losing the valuable genetic properties of the wild plant. The results have been published in the current issue of Nature Biotechnology.

People with fewer resources contribute more to actions against climate change

A research analyse the connection between purchasing power and actions against climate change

People with fewer resources contribute more to actions against climate change. This is the main result of a research that, by making a civic science experiment, suggests to act collectively fighting the climate change. The study, in which it has been measured how a group of people acts against a common harm, has shown that people are more or less likely to contribute money to fighting climate change depending on how wealthy they are. These are the principal findings of a research published in the journal PLOS ONE by researchers from the Universitat Rovira i Virgili, the University of Barcelona, the University of Zaragoza and the Carlos III University of Madrid.

Mysteries of a golden beetle

Human sisters may look extremely different from one another. What does that have to do with gold, black and red beetles?

As the sun set over the cloud forest in western Panama, Lynette Strickland still hadn’t found what she was looking for. Strickland spent all day exploring Fortuna, a mountainous area spanning the Continental Divide near the border of Panama and Costa Rica, in search of a glimmering golden beetle. But each time she flipped over a leaf or asked Smithsonian beetle expert Don Windsor ‘Is that it?’ the answer was ‘No'.

Development of sensors that avoid carbon monoxide, natural gas or bottled gas poisoning

Currently, there are more than 250 deaths caused by gas and 2,000 poisonings per year in Argentina. In Spain, the figures are lower butstill quite high, with a hundred deaths per year

The Theoretical and Computational Chemistry Group of the Universitat Jaume I, led by the professor of Physical Chemistry Juan Andrés Bort, has participated in an international research project for the development of electronic sensors that prevent carbon monoxide, naturalgas and bottled gas poisoning. The work has served as a basis for a bill in Argentina to establish the obligatory nature of installing toxic and explosive gas sensors that have a gas cutting mechanism in public spaces.

However these secondary forests - forests regrowing in previously deforested areas - are still vitally important to biodiversity conservation and carbon storage, argue scientists.

Leishmaniasis is a parasitic disease transmitted to humans by the bite of the infected female sandfly. With 50,000 to 90,000 new cases worldwide each year

Researchers at the University of York have identified genes in a parasite that could help clinicians predict drug treatment outcomes for patients with visceral leishmaniasis in Brazil. The findings could lead to a new prognostic test that can predict which patients will respond well to drug treatment and which patients need alternative solutions.

The constructive role of noise

International research with the participation of the UC3M

Noise can induce spatial and temporal order in non-linear systems, which helps to detect and amplify weak external signals that are difficult to detect by conventional amplifiers, according to an international team composed of researchers from Germany, China and Spain in which the Universidad Carlos III de Madrid (UC3M) is a participant. The work, published in two articles of the Physical Review Letters magazine, explains that this effect can be used in the decoding and in the creation of extremely weak signals, without the need for a reference signal and in a much shorter time than with a conventional amplifier.
