Researchers investigate genes that endow tumor cells with stem cell-like properties

In vitro experiments were performed on cell lines derived from medulloblastoma tumors, the most common type of brain cancer in children

Researchers at the University of São Paulo’s Bioscience Institute (IB-USP) in Brazil are studying a group of human genes that, when expressed in malignant tumors, endow tumor cells with properties similar to those of stem cells, making them more aggressive and resistant to treatment.

Seisms in Venus?

David Tovar a UNal Geologist and University of Minnesota Geological Sciences masters candidate is using planetary geology for researching a very small region in Venus to study global heat diffusion average in heavily fractured areas

“Despite not being able to observe the surface directly due to its dense atmosphere, there is a region called Alpha with high fracturing with faults and folds (an area of approximately 700,000 square km and similar to the size of Texas) that evidence some type of seismic activity,” said Tovar, Cofounder and Codirector of the UNal Planetary Geology and Astrobiology Research Group (TITAN, for its Spanish acronym).

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.

Analyzing the keys to environmental mobilization through social networks

Recognizing an opportunity, defining a clear message and reacting; these are the three keys

Recognizing an opportunity, defining a clear message and reacting; these are the three keys to the success of environmental campaigns on social networks, according to research by Universidad Carlos III de Madrid (UC3M) and INGENIO, a joint center of the Universidad Politécnica de Valencia and CSIC, which also received an international award for the best article about entrepreneurship.

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.

Half of the most popular news on Twitter is not covered by traditional news media sources

Half of the news that appears on Twitter as “trending topics” goes unmentioned in the traditional news media

Half of the news that appears on Twitter as “trending topics” goes unmentioned in the traditional news media, and when both sources carry it, 60% of the stories appear first on the social network. Those are some of the conclusions of a study which analyzes the dissemination of news on Twitter compared with the traditional media.

Project set to investigate origins of mineral deposits on floor of Atlantic

An international consortium of scientists from universities and research institutions in Brazil and the United Kingdom plans to find out how these polymetallic deposits

Deposits of various metals can be found in some areas of the ocean bottom at water depths as great as 5,000 m. The most frequent are manganese nodules with diameters of 10-20 cm. They cover much of the deep sea floor in the surface layer of sediment and contain iron, copper, nickel and cobalt as well as manganese.

Nutritional value of Amazonian palm oil is similar to olive oil

One of the purposes of this research project headed by Professor María Soledad Hernández is to maximize oil extraction carried out by Amazonian Indian communities

Analysis carried out on sehe palm oil determined great nutritional similarities with olive oil. Furthermore they discovered high Omega 3 and 9 levels, superior to African palm oil. As deduced from a UNal Food Science and Technology Institute (ICTA, for its Spanish acronym) research project which focused on obtaining sehe palm (Oenocarpus bataua) oil and its uses. This palm originally found in the Amazonian region also thrives in the Provinces of Chocó and Boyacá and the eastern plains.

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.

Growing guppy fish to fight chikungunya vector

Use of fish for biological control has been also implemented in Brazil and Peru as well as other cities in Colombia

Guppy fish reared at UNal-Palmira fish tanks between three to five centimetres long are now an economic and effective alternative for attacking the chikungunya causing mosquito in the city of Cali, Province of Valle del Cauca. This technique was used seven years ago by UNal Zootechnician and Animal Science PhD José Ader Gómez to biologically control Aedes Aegypti mosquitos, the dengue fever transmitting vector.
