A Terahertz generator with the highest signal quality

Researchers at the Universidad Carlos III of Madrid (UC3M) and the firm Luz WaveLabs are developing an innovative Terahertz generator

Researchers at the Universidad Carlos III of Madrid (UC3M) and the firm Luz WaveLabs are developing an innovative Terahertz generator that improves signal quality by one million times as compared to the best device of this kind currently on the market; it will allow this technology to be applied in the areas of biomedicine, transportation safety, industry and radio astronomy, among others.

Google+ registers many users, but few are active

A research group at Universidad Carlos III of Madrid (UC3M) has analyzed the first months that Google+ has been functioning to study its popularity and compare this platform to others, such as Facebook and Twitter

Social networks have become the Internet’s most used applications. Among these, Facebook and Twitter dominate the market, with billions of users. Given this scenario, “Google, the internet giant, realized that in order to maintain its dominant position, it would have to get involved in the social network market,” declares one of the authors of the study, Rubén Cuevas, of UC3M’s Telematic Engineering Department. His study seeks to settle the debate regarding the success of Google+. On one hand, Google has, on several occasions, declared its social network a huge success; on the other hand, some experts and media sources, such as the Wall Street Journal, have nicknamed the network a “ghost town”.

Advances in the identification of novel targets for prolactinoma treatments

CONICET scientists study inhibitory effects of the prolactin secretion and cell proliferation to counterbalance the development of these tumours

In the year 2010, a study of the Division of Endocrinology of the “Hospital de Clinicas José de San Martin” showed that 79 per cent of the patients diagnosed with lesions on the hypothalamic- hypophyseal area of the brain had tumours at the base of the brain, and of those, 19 per cent were prolactinomas, a type of benign tumour of the pituitary gland that is responsible for several hormone secretions.

Forensic entomology: crime solving insects

For more than a decade researchers at the University of Antioquia have been studying forensic entomology and compiled a vast collection of insect species that can help determine the elapsed time since a person has died

“Insects are fascinating,” says Professor Martha Wolf, an entomologist at the University of Antioquia who has long been devoted to study the role of insects in death investigations, and current director of the UA Entomology Group (GEUA), established in 1997. The use of insects in forensic investigations dates back to the 13th century in China as evidenced by Chinese physician and forensic expert Song Ci (also known as Sung T’zu) in his book “The washing away of wrongs”.

The tick holds the key

Molecular techniques allow detecting and determining the population dynamics of a bacterium that uses ticks as vectors

Lucas Monje is 35, holds a PhD in Biological Sciences and is a CONICET assistant researcher at the Laboratory of Disease Ecology of the Institute of Veterinary Sciences (ICIVET-LITORAL, CONICET-UNL). Although he works in the field of molecular biology, “the subject that I became directly involved with is an investigation that tries to elucidate the eco- epidemiology of Rickettsia parkeri, a bacterium that causes emerging infectious diseases”, he explains.

UA-led research team develops plant-based biofuel

Researchers at the University of Antioquia have managed to produce biofuel from aquatic plants

Most of Ayapel inhabitants derive their livelihood from hunting, fishing and agriculture. However, these resources are being drastically depleted as a result of overexploitation and deforestation. Also overfishing has led to a decline in populations of several species including shad, catfish and bocachico. Illegal gold mining and drop in rice prices due to free trade agreements are also problems affecting this region.

ALMA reveals ghostly shape of ‘coldest place in the universe’

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have taken a new look at this intriguing object

At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang Nebula is the coldest known object in the Universe – colder, in fact, than the faint afterglow of the Big Bang, which is the natural background temperature of space.

ALMA Probes Mysteries of Jets from Giant Black Holes

Astronomers obtained the best view yet of the molecular gas around a nearby

Two international teams of astronomers have used the power of the Atacama Large Millimeter/submillimeter Array (ALMA) to focus on jets from the huge black holes at the centres of galaxies and observe how they affect their surroundings. They have respectively obtained the best view yet of the molecular gas around a nearby, quiet black hole and caught an unexpected glimpse of the base of a powerful jet close to a distant black hole.

Researches in the late roman site of 'El Castillón' reveal a longer occupation for the settlement

Last summer fieldworks revealed that the settlement of Santa Eulalia was inhabited until the 7th century AD

Last campaign of excavations at El Castillon (located in Santa Eulalia de Tabara, Zamora, Northwestern Spain) have revealed that this Late Roman town was occupied for a longer period of time than the determined by the scientists so far. Prior dating placed the last dwellers of El Castillon not beyond the 5th century AD, but in the 2013 fieldwork, the archaeologists have discovered artefacts enabling to enlarge the chronology of the site until a period between the 6th and the 8th centuries, then the Early Middle Ages.

Ubiquitin: small things matter

As a great recycling machine, this protein labels molecules that must be degraded and eliminates them, in an attempt to control many of the essential functions of the cell
Protein degradation, cell growth regulation, DNA repair, neural and muscle degeneration and response to stress are some of the functions that ubiquitin, a small protein that is found in most body cells, regulates. Its name comes from the Latin word ubīque, which means “everywhere”. Gastón Soria. Foto: gentileza investigador.
