In search of comprehension of archaeological contexts in Tucumán

CONICET researchers study prehispanic agricultural practices, its history and ways of inhabiting the Calchaquí Valley

As testimonies of pre-Columbian Cultures, Archaeological sites of the province of Tucumán conserve emblematic fragments of the history of South America. There are Inca settlements and vestiges of previous aboriginal cultures where their practices before the Spanish conquest remain explicit.

Scientists collaborated on a study on the origins of the domestic dog

Two Argentine anthropologists participated in an investigation that suggests that the link between men and canids started in Europe

The geographic and temporary origins of the canids’ domestication have aroused controversy in the scientific field. Although there are hypotheses that support the fact that this process initiated 15.000 years ago in the east of Asia, the results of a recent study – where Argentine researchers participated – indicate that the process would have started in Europe between 18.800 and 32.100 years ago.

ALMA Discovers a Formation Site of a Giant Planetary System

A team of Japanese astronomers has obtained a firm evidence of formation of a giant planetary system around a young star by the observations with the Atacama Large Millimeter/submillimeter Array (ALMA)

The research team, led by astronomers at Osaka University and Ibaraki University, observed with ALMA a young star named HD142527 in the constellation Lupus (the Wolf). The ALMA image shows that cosmic dust, which is component material of planets, is circling around the star in a form of asymmetric ring. By measuring the density of dust in the densest part of the ring, the astronomers found that it is highly possible that Jupiter-like giant gaseous planets or Earth-like rocky planets are now being formed in that region. This region is far from the central star, about 5 times larger than the distance between the Sun and the Neptune. This is the first firm evidence of planet formation found so far from the central star in a protoplanetary disk. The research team plans further observations of HD142527 with ALMA for closer investigation, as well as other protoplanetary disks to have a comprehensive understanding of the planet formation in general.

Looking to obtain bone substitute with synthetic materials

Hydroxylapatite obtained synthetically is a fragile “ceramic”. Collagen and organic matter are what give resistance to bones

 

When Lucia Téllez Jurado and her research team at the National Polytechnic Institute (IPN) were working in the synthesis of diverse materials, they realized that the Hydroxylapatite, medullar component of the bone, when obtained synthetically and “giving” it some characteristics, could be used as a bone substitute.

Mexican Researcher identifies new species of marine algae

This finding was made by Jazmín Hernández Kantun, marine biologist at the Autonomous University of South Baja California (UABCS)

The species that historically was quoted as the most abundant of coral algae that forms rodoliths at the Gulf of California in Mexico, is in reality a compound of five different species. This finding was made by Jazmín Hernández Kantun, marine biologist at the Autonomous University of South Baja California (UABCS), resulting in a change of paradigm in the study of the species known as Lithophyllum margaritae.

A new, more economical sonification prototype to assist the blind

Researchers at Universidad Carlos III de Madrid (UC3M) have developed an assistive technology system that works by sounds which contributes to the autonomy of persons with visual impairments

The commercial systems that exist today in Spain for the mobility of persons with sight impairment are insufficient, according to theseUC3M researchers, because they are costly and too bulky. The assistive technology, conceived as a sound guide that gives information as to the user’s environment, precisely aims to make this ingenious complement to the classic cane or guide dog more economical. This system’s functioning is spelled out in the doctoral thesis of Pablo Revuelta Sanz, directed by the UC3M professors, Belén Ruíz Mezcua y José Manuel Sánchez Pena, who also belong to the Spanish National Centre for Subtitling and Audio-description (CESyA).

Using math, researcher seek to improve success in transplants

The process consists in knowing the type of proteins in charge of metabolizing the drugs (enzymes) for each patient which would, helped by a mathematical model, allow to establish the exact dose needed of the immunosuppressive drugs required

 

Given that 10.5 % of patients who receive a transplant reject the new organ, researchers at the Center of Research and Advanced Studies of the National Polytechnic Institute (Cinvestav) are working in the design of a tool capable of preventing this problem. The process consists in knowing the type of proteins in charge of metabolizing the drugs (enzymes) for each patient which would, helped by a mathematical model, allow to establish the exact dose needed of the immunosuppressive drugs required.

Supernova’s Super Dust Factory Imaged with ALMA

Striking new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust

Galaxies can be remarkably dusty places and supernovas are thought to be a primary source of that dust, especially in the early Universe. Direct evidence of a supernova’s dust-making capabilities, however, has been slim and cannot account for the copious amount of dust detected in young, distant galaxies.

Volcanic ash touted as raw material for textile industry

Tecnológico de Monterrey Puebla Campus students and researchers show that due to its fine consistency and abrasive quality, volcanic ash can be employed to distress fabric in place of the most commonly used material: pumice stone

Said Robles, Director of the Automotive Engineering Master's program, and Sergio Castillo, a Civil Engineering student, have developed a method to separate volcano ash components and obtain silica, cristobalite, and alumina, components of extreme hardness that can act on other materials through mechanical efforts like grinding, cutting or polishing.

Battle of the Titans: Two Black Holes in Action

With the Canaricam instrument on the Gran Telescopio CANARIAS (GTC), a team of researchers known as ‘Los Piratas’ have caught a system of two galaxies fused together in collision, feeding two black holes at their centres

rp 299 is the name given to two galaxies (NGC3690 + IC694) in collision. This interacting system is at a relatively early stage in its chance encounter. Both galaxies have an active nucleus (called Active Galactic Nuclei – AGN) that host black holes in their interiors. Now, for the first time, it has been possible to isolate the mid-infrared emission from the two simultaneously emitting interacting nuclei.

The first cancer operation room with a navigator is created

The system, presented at Gregorio Marañón Hospital, permits real-time interaction with the body of the patient

A team of researchers from Gregorio Marañón Hospital, the company GMV and the Universidad Carlos III de Madrid (UC3M) have started the first cancer operation room with a navigator. This image-guided system will allow for increased intraoperative radiotherapy safety. The system, presented at Gregorio Marañón Hospital, permits real-time interaction with the body of the patient (with its different tissues and cancer) as well as the radiotherapy applicator used to radiate the area affected by the tumor. This innovation will be used in the surgery of cancers treated with intraoperative radiotherapy in the hope of achieving greater precision in the radiation of potentially cancerous tissues after the removal of the tumor.

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”.
