A UC3M study analyzes the “virality” of Twitter in electoral processes

there are two levels of conversation with scarcely any points of connection: on one level are the politicians, on the other are the citizens

Research carried out at the Universidad Carlos III de Madrid (UC3M) analyzes the participation and receptivity of the messages emitted during the last European elections in 2014. The main conclusion the study reached is that there are two levels of conversation with scarcely any points of connection: on one level are the politicians, controlled by the parties and candidates; on the other are the citizens, freer in their structure and the subjects dealt with.

Biologists discover skydiving spiders in South American forests

Arachnophobes fearful of spiders jumping, creeping or falling into their beds now have something new to worry about. Some spiders might also glide in through the window

A group of biologists working in Panama and Peru have discovered a type of nocturnal hunting spider, about two inches across that is able to steer while falling, much like a wingsuit flyer, in order to return to the tree from which it fell.

Catalysis: the key to the success of chemical processes

Researchers at the CONICET study materials to make chemical reactions more efficient in the petrochemical and oleo chemical industry

At a single glance, an exhaust pipe and a washing powder seem to have nothing in common; however, they both contain therein substances, catalysts, which accelerate the rate of a chemical reaction without changing the end product. From the times of the old alchemists to this time, scientists have studied the mixtures of products that increase the efficiency of the new compounds that are produced from them. Nowadays, more than 80% of the industrial products we consume are produced from catalysis.

ALMA discover how lowly dwarf galaxy becomes star-forming powerhouse

An international team of astronomers has discovered an unexpected population of compact interstellar clouds hidden within the nearby dwarf irregular galaxy

A nearby dwarf galaxy poses an intriguing mystery: How is it able to form brilliant star clusters without the dusty, gas-rich environments found in larger galaxies? The answer, astronomers believe, lies in densely packed and previously unrecognized nuggets of star-forming material sprinkled throughout the galaxy.

ALMA witnesses assembly of galaxies in the early universe for the first time

By combining the new ALMA observations with computer simulations, it has been possible to understand in detail key processes occurring within the first galaxies

The Atacama Large Millimeter/submillimeter Array (ALMA) has been used to detect the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronomers to start to see how the first galaxies were built up and how they cleared the cosmic fog during the era of reionization. This is the first time that such galaxies are seen as more than just faint blobs.

The Captain fish will repopulate the Cundinamarca-Boyacá Provinces high plateau water bodies

UNal researchers are currently working on a repopulation plan on the water sources of the Cundinamarca-Boyacá Provinces high plateau from a sample of 90 species gathered in the high basin of the Bogotá River

The captain fish (Eremophilus mutisii) is a solitary, calm and endemic fish which was lost from the memory of Colombians, especially the inhabitants of the Savannah of Bogotá. The tributaries of the Negro, Frío, Chicú, Balsillas, Juan Amarillo, Fucha, Tunjuelo and Soacha Rivers were formerly the natural habitat of the cold water guardian and was one of the main food sources of the region.

Glass ceramic material is effective for treatment of dentin hypersensitivity

The material is also being tested in ocular implants and artificial middle ear bones, among other applications

Researchers at the University of São Paulo’s Dentistry School in Ribeirão Preto, São Paulo State, Brazil, are testing a glass-ceramic material for use in the treatment of dentin hypersensitivity. This condition, which manifests as acute pain in response to hot or cold drinks and food, arises from exposed dentin surfaces due to receding gums. Dentin is the tissue that forms the bulk of a tooth.

Nanometric sensor designed to detect herbicides can help diagnose multiple sclerosis

The nanobiosensor consists of a silicon nitride or silicon nanoprobe with a molecular-scale elastic constant and a nanotip coupled to an enzyme, protein or other molecule

The early diagnosis of certain types of cancer, as well as nervous system diseases such as multiple sclerosis and neuromyelitis optica, may soon be facilitated by the use of a new detection device: a nanometric sensor capable of identifying biomarkers of these pathological conditions. The nanobiosensor was developed at the Federal University of São Carlos (UFSCar), Sorocaba, in partnership with the São Paulo Federal Institute of Education, Science & Technology (IFSP), Itapetininga, São Paulo State, Brazil. It was originally designed to detect herbicides, heavy metals and other pollutants. An article about the nanobiosensor has just been published as a cover feature by IEEE Sensors Journal.

ALMA detects first traces of carbon ‘smog’ permeating interstellar atmospheres of early galaxies

ALMA, with its unprecedented sensitivity, was able to detect the faint but ubiquitous millimeter 'glow' of ionized carbon in the interstellar atmospheres of nine very distant

Astronomers study the elements scattered between the stars to learn about the internal workings of galaxies, their motion and chemistry. To date, however, attempts to detect the telltale radio signature of carbon in the very early Universe have been thwarted, perhaps – as some have speculated – by the need to allow a few billion years more for stars to manufacture sufficient quantities to be observed across such vast cosmic distances.

A new method transforms industrial waste into cement

Researchers from the University of Aveiro are developing a system to reduce the ecological footprint of one of the industries with most CO2 emissions in the world

A group of the Research Centre for Ceramic Materials and Compounds (Centro de Investigação em Materiais Cerâmicos e Compósitos, CICECO) of the University of Aveiro has produced a new type of cement based on industrial waste. This new system, which has only so far been tested experimentally, needs less energy and uses only waste, which means that its implementation would reduce the environmental impact of the cement industry.
