Cases of infection by Janibacter terrae in humans are published for the first time

The study published in the ‘Infection’ journal shows that this bacteria is not only present in the environment, as up to now it had been exclusively isolated from the soil

Researchers from the departments of Clinical Microbiology and Internal Medicine of the University Welfare Complex of León, the Institute of Biomedicine of the University of León (IBIOMED), the National Microbiology Centre of the Carlos III Health Institute, and the University School of Physiotherapy of the Spanish Organisation for the Blind (Organización Nacional de Ciegos Españoles, ONCE) of Madrid have published for the first time four cases of bacteremia (the presence of bacteria in the blood) owing to Janibacter terrae in humans.

Complex organic molecules discovered in infant star system: hints that prebiotic chemistry is universal

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star

This discovery, made with the Atacama Large Millimeter/submillimeter Array (ALMA), reveals that the protoplanetary disk surrounding the million-year-old star MWC 480 is brimming with methyl cyanide (CH3CN), a complex carbon-based molecule. Both this molecule and its simpler cousin hydrogen cyanide (HCN) were found in the cold outer reaches of the star's newly formed disk, in a region that astronomers believe is analogous to our own Kuiper Belt -- the realm of icy planetesimals and comets beyond Neptune.

The key to treat cardiovascular diseases could lie in the heart of the fruit fly

Researchers at Conicet use this insect as a study model to find information about heart failures or arrhythmia in humans

Drosophila melanogaster is the scientific name of the fruit fly. Apart from the morphological differences they have with human beings, both have similar genetic characteristics. For this reason, the insect has been usually used as a study model for human cardiovascular diseases. A group of scientists, led by Paola Ferrero, assistant researcher of the Conicet at the Cardiovascular Research Centre (Centro de Investigaciones Cardiovasculares CIC, Conicet – UNLP), undertake a project called “Drosophila melanogaster as a study model to research into human cardiovascular diseases”.

A study shows serious deficiencies in the sex education of university students

A study of the University of Salamanca alerts us to the dependence of young women on their partners

A study of the University of Salamanca shows a great lack of knowledge of sexual health among young university students of the first academic years of this institution. Ignorance of diseases of sexual transmission and risky behaviour are common. Moreover, the research also detected that young women have a high emotional dependence on their male partners; this was not the case in previous generations.

Jupiter satellite similar to Earth in its beginnings

The volcanic activity from Io, a satellite of Jupiter is similar to that of Earth in its beginnings. This was a conclusion of the first research project on planetary volcanology carried out at UNal

According to UNal alumnus and US doctoral volcanology candidate, David Fernando Tovar, this discovery leads to the idea that comparing the situation of Earth with this Jupiter moon, volcanic activity is considerable greater in the latter.

New advances in the fight against cancer

A study reveals the interactions among certain microorganisms, the immune system and the development of tumors

A collaborative study between the laboratory of researcher José Conejo García of the University of Philadelphia, USA, and the Laboratorio de Inmunopatología del Instituto de Biología y Medicina Experimental (IBYME, CONICET-FIBYME) revealed the relationship between certain microbes and the growth of distal tumor in the organism. According to the result, some intestinal bacteria activate Toll-like receptors (Toll 5 or TLR5). This leads to several inflammations that trigger tumor growth. For the researchers, the possibility of deciphering the interactions between some microbes and the immune system will promote the discovery of new ways to battle cancer.

ALMA Disentangles Complex Birth of Giant Stars

The observation results shows the presence of multiple, or at least two, gas outflows from a protostar, indicating the possible existence of two new-born stars in this region

A research group led by Aya Higuchi, a researcher at Ibaraki University in Japan, conducted observations of the massive-star forming region IRAS 16547-4247 with the Atacama Large Millimeter/submillimeter Array (ALMA). The observation results shows the presence of multiple, or at least two, gas outflows from a protostar, indicating the possible existence of two new-born stars in this region. Also, the radio observation results of molecular line emission of methanol revealed in vivid detail an hourglass structure created by gas outflows spreading outward while thrusting the ambient gas cloud away. It is the first time that such an hourglass structure was found in observations of methanol in high-mass star forming regions.

Orchid bees in the fast lane

To test a controversial theory about what sets the pace of life, scientists compare metabolism and membrane lipid composition of 22 species of orchid bees

To test a controversial theory about what sets the pace of life, scientists worked at the Smithsonian Tropical Research Institute (STRI) in Panama to compare metabolism and membrane lipid composition of 22 species of orchid bees of different sizes. Their findings support a theory that the cell membranes of animals in the fast lane—that have high metabolic rates—are different from the cell membranes of animals with a slower pace of life, at least in the proportion of the fatty acids they contain.

Learning to look after water

Researchers of the Conicet participate in a project with schools to control water quality of rivers and streams in the province of Tucumán

Water is tasteless, colourless and odourless; and it is more than two hydrogen atoms bonded to one oxygen: it is essential for the development of life. Although it covers more than 70% of the land surface, only 1% of the fresh water is available because the rest is mainly in the sea and the poles. Thus, water is a very scarce resource so it must be looked after and used rationality.

The digital showcase of radio

A project of the Universidad Pontificia de Salamanca aims to make programme planning information and access to the broadcasts of all Spanish radios available to all listeners in a single Internet application

First day of class at the Faculty of Communication Studies. The lecturer is talking about "the dial" of the radio. The what? Some of the young people are not familiar with the term. They have probably never tried to tune in to a radio station on a traditional radio with its dial and numbers indicating the various frequencies on the Medium Wave (MW) or Frequency Modulation (FM) band. They belong to a generation that has grown up with digital media and with mobile phones that give access to almost all contents. The anecdote dates from the beginning of this academic year and reveals a new situation to which not all traditional means of communication are adapting in the same way.

Valladolid researchers help to shed light on the origin of Indo-European languages

A study published in the Nature magazine reveals that 4,500 years ago there was a massive migration of peoples from the Russian steppes to Central Europe, which favoured the expansion of Indo-European languages

Reseachers of the Prehistory and Archaeology Department of the Universidad de Valladolid (UVA) were part of the international scientific team that has shed light on the origin and expansion of Indo-European languages. In order to achieve this the most wide-ranging research work involving ancient DNA to date has been carried out, to be precise of 69 individuals who lived in Europe between 3,000 and 8,000 years ago.
