Study explores mitochondrial-nuclear communication pathway

Considered highly important organelles in eukaryotic cells because they act as cell ‘powerhouses’, mitochondria must be in constant communication with cell nuclei, where the proteins that they require are encoded

Communication follows several different pathways. In the most studied of these pathways, the signal leaves the nucleus and travels to the mitochondrion. In other, less well-known pathways, the signal moves in the opposite direction. For this reason, these pathways are known as retrograde signaling pathways. In experiments with yeast of the species Saccharomyces cerevisiae, which is the type used to make bread, beer, wine and cheese, Brazilian researchers have investigated for the first time what happens to mitochondria when one of these retrograde pathways, mediated by Rtg proteins, does not work properly.

Gravity-aided ALMA maps dstant monstrous galaxy

As a result, ALMA was able to observe clumps of star formation in the galaxy down to a size of approximately 200 light-years across. This is the first time this phenomenon has been seen at such an enormous distance

In 2014, ALMA's Long Baseline Campaign, separated it's antennas for up to 15 kilometers and produced a spectacularly detailed image of the distant, gravitationally lensed galaxy SDP.81. New analyses of this image reveal details never before seen in a galaxy so remote, including phenomenally massive yet concentrated clumps of star-forming material. The ALMA observations of SDP.81 were enabled by a cosmic effect known as gravitational lensing. A large galaxy nestled between SDP.81 and ALMA is acting as a lens, magnifying the more distant galaxy's light and warping it into a near-perfect example of a phenomenon known as an Einstein Ring.

School failure could be reduced by 80% if maths and English were concentrated on

The Didactic Excellence, innovation, and Quality Research Group of the Universidad de León (ULE) is researching school failure and success in primary and secondary education

It is estimated that some 23 per cent of non university students fail in their studies. This is particularly relevant in Spain, which has the highest rate of school failure in the European Union according to recent data from EuroStat (the European Statistics Office).

The websites of political parties do not encourage communication with citizens

A study of the Universidad de Beira Interior analyses the websites of Portuguese political parties, which are more orientated towards the dissemination of messages than participation

A research project of the Universidad de Beira Interior has carried out a three-year analysis of the websites of Portuguese political parties to study their method of communication with citizens by this medium. The conclusions show that there is little interaction; political parties do not want to lose control of their message and use the Internet as an instrument of dissemination but not for listening to their potential voters.

Mexican quantum computing pioneer ventures to answer nature's mysteries

Tecnológico de Monterrey School of Engineering and Sciences researcher Salvador E. Venegas-Andraca, PhD. heads a team of computer scientists whose proposal was declared the winner in a NASA contest to try out the world's most advanced quantum computer

There is a very small number of quantum computers in the world, and when NASA in collaboration with Google recently purchased one of the most advanced models manufactured by Canada's D-Wave and installed it at NASA's Ames Research Center at what they named the Quantum Artificial Intelligence Laboratory (QuAIL), it decided to donate 20% of its number crunching time to the international scientific community. To this end, it put out a call for proposals.

“Calcium batteries might be more powerful than lithium batteries”

Interview with Jean-Yves Sánchez

Jean-Yves Sánchez researches the development of calcium batteries that can compete with lithium batteries. He is carrying out the study under the auspices of CONEX, a talent attraction program that hires experienced international researchers. The program is funded by Universidad Carlos III de Madrid (UC3M), the European Union (Marie Curie actions from the “People” programme of the Seventh Framework Programme), the Ministry of the Economy and Competitiveness and the Banco Santander. The author of more than 140 scientific articles and 43 international patents, he has advised 32 doctoral theses and led three European projects and over a dozen national and regional projects in the field of electrochemical energy.

Researchers from León point to gene IL26 as a candidate for measuring tuberculosis susceptibility

In a study published in the ‘Immunology’ journal a scientific team from the Complejo Asistencial Universitario de León and the Ibiomed has taken a closer look at tuberculosis susceptibility in the elderly

Not all people infected by tuberculosis bacteria (Mycobacterium tuberculosis) fall ill. It is estimated that almost a third of the world's population is infected, but only a small percentage (some 8.6 million people) actually develop the disease. Researchers from the Internal Medicine Service of the Complejo Asistencial Universitario de León (CAULE) and the Instituto de Biomedicina (Ibiomed) of the University of León have been working for seven years on the analysis of the immune response to tuberculosis.

The factors influencing the purchase of on-line travel are being studied

The Universidade da Beira Interior is drawing up a model for analysing the tourism sector on the Internet and is carrying out an extensive survey of users from all over the world

The volume of purchases over the Internet is becoming an increasingly important part of the economy as a whole and of the tourism sector in particular. The contracting of transport, hotels, or complete travel packages are among the most habitual Internet transactions. For this reason the Economy and Management Department of the Universidade da Beira Interior has studied the factors that influence travellers when purchasing on-line.

The modulation of the alcoholic strength of wines is researched by using plant hormones

The scientific team of the Vine and Wine Research Institute of the University of León has carried out an experimental test in collaboration with a wine cellar of the Toro Denomination of Origin

The Vine and Wine Research Institute of the University of León (ULE) has initiated a novel area of study on the modulation of the alcoholic strength of musts at the time of the harvest by the application of hormones. This research has great potential as alcoholic strength is an essential parameter in the production of wine not only from a business viewpoint but is also associated with numerous organoleptic characteristics and in short with its quality.

The University of Aveiro studies the properties of cork chipboard

The scientists' objective is to find new applications for a product that is very important to the Portuguese economy

The most common use given to cork is that of the manufacture of cork stoppers for bottles. However, this activity generates a large amount of cork waste that is made use of to produce chipboard, which has many applications. Researchers from the University of Aveiro are analysing the characteristics of cork chipboard and in particular how this material responds to different load or impact resistance conditions.
