Corn's anticancer therapy potential probed

Tecnológico de Monterrey Biotechnology PhD candidate Margarita Ortiz has published a paper on the subject in the Journal of Proteomics, the world's foremost magazine on the large-scale study of proteins

It is a proven fact that corn and other grains hold huge health care potential because their proteins and peptides (components of smaller size, but same composition as proteins) contain antioxidant and anticancer properties. In addition, their compounds have a role in preventing and treating chronic degenerative diseases.

Agave: not just for tequila

Agave angustifolia, a species native to Panama, performs well even in the extreme conditions that may become more prevalent under climate change scenarios

Our world contains roughly 400 million hectares of abandoned agricultural land, much of it in the tropics and subtropics. Both Agave tequilana, the source of tequila and Agave fourcroydes, a common source of fiber, grow well on seasonally arid lands and have been proposed as biofuel crops.

“Ghost light” from dead galaxies

Researchers from the IAC and the ULL, using the Hubble Space Telescope, have observed the remains of the destruction of galaxies on a large scale, and make a significant contribution to our understanding of how the large scale structure of the universe ha

The intra-cluster light, the “ghost light” in galaxy clusters, comes from stars in clusters which are not bound by gravity to any particular galaxy. According to theoretical predictions, huge tidal forces should destroy galaxies and cause stars to wander freely in the galaxy clusters. For this reason knowing more about the properties of this intra-cluster light gives us clues about the formation and evolution of clusters of galaxies. However the big problem facing astronomers who study this light is that it is very faint, and therefore difficult to observe. It must also be studied in zones well away from the galaxies in the cluster, which are not contaminated by the outer parts of any of these galaxies.

Planet-forming lifeline discovered in a binary star system

The results are published today in the journal 'Nature'

For the first time, researchers using ALMA have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets. The results are published today in the journal Nature.

Forensic Science: an interdisciplinary contribution to justice

CENPAT professionals provide scientific services for forensic examinations requested by the Ministerio Público Fiscal del Chubut [Public Prosecutor’s Office of the province of Chubut]

Every crime scene has evidence that can lead to the identification of the perpetrator. Although most of it is imperceptible at a simple glance, it can be recovered by specialists working in genetics, anthropology, entomology and archaeology, for instance. And most frequently these disciplines complement one another to interpret evidence.

Cactus extract reduces glucose levels

When the glucose levels fell by 30% they found that in some way these results were related to what was reported by popular belief

How can cactus juice help reduce blood sugar levels? This was the topic of a research project headed by the UNal Laboratory of Natural Products. Although the cactus Opuntia cochenillifera was collected in the city of Ibagué, capital of the Province of Tolima, it is distributed in several areas through the Colombian territory, specifically in the Andean region.

Enzymes from Antarctica have industrial use

The South Pole fungi were stored in the Brazilian Collection of Environmental and Industrial Microorganisms, which belongs to the Multidisciplinary Center for Chemical, Biological and Agricultural Research at the University of Campinas

The manufacture of detergents, cosmetics, food, medicines and many other chemical products depends on processes carried out by enzymes, which are organic catalysts that enable many chemical reactions. Among the enzymes of interest to industry, the most readily employed are the proteases, which account for 60% of the world’s enzyme market.

Smithsonian scientists discover tropical tree microbiome in Panama

Bacteria in tropical forests may also play a vital role, protecting leaves against pathogens and even affecting the ability of forests to respond to climate change

Human skin and gut microbes influence processes from digestion to disease resistance. Despite the fact that tropical forests are the most biodiverse terrestrial ecosystems on the planet, more is known about belly-button bacteria than bacteria on trees in the tropics. Smithsonian scientists and colleagues working on Panama’s Barro Colorado Island discovered that small leaf samples from a single tree were home to more than 400 different kinds of bacteria. The combined sample from 57 tree species contained more than 7,000 different kinds.

Organic Molecules in Titan's Atmosphere Are Intriguingly Skewed

This discovery may help astronomers better understand the processes that shape this world's complex chemistry

While studying the atmosphere on Saturn’s moon Titan, scientists discovered intriguing zones of organic molecules unexpectedly shifted away from its north and south poles. These misaligned features seem to defy conventional thinking about Titan’s windy atmosphere, which should quickly smear out such off-axis concentrations.

Iodine excess discovered in children of the Bogotá savannah

The research project included a total of 125 children, 47 from the municipality of Chia and 78 from the southern district of Bogotá known as Bosa. All children underwent an anthropometry, an echography and urine testing

A research project carried out in the municipalities Chía and Bosa, on 6 and 15 year old students demonstrated excess iodine levels in children. According to UNal Medicine Professor Roberto Franco the only confirmed role of iodine in the human body is related to thyroid hormone synthesis. Nevertheless, iodine excess produces goiter, hypothyroidism (low thyroid production) or hyperthyroidism (high thyroid production).

Study reveals involvement of nitric oxide in the allergic process

According to the authors, nitric oxide promotes the differentiation of a specific type of defense cell – lymphocyte T helper 9 (Th9) – responsible for secreting a substance known as interleukin-9 (IL-9)

A study published in the journal Nature Communications has described the mechanisms through which nitric oxide – a gas naturally synthesized by endothelial cells, defense cells such as macrophages, and certain types of neurons – contributes to the exacerbation of allergic responses.

Blood plasma could help regenerate wounds and burns

The idea is for the biomaterial to not simply cover the wound to conceal the area

A blood plasma gel produced by UNal researchers could help the scarring process of deep wounds and sores produced from too much time lying down or sitting on a wheel chair. UNal Engineering Department Professor Rubén Darío Godoy says the purpose of their work is to produce a soft scarring process (from the esthetic standpoint) and to hasten the healing process.

New findings in the Archaeological site of El Castillon (North-western Spain) contribute to the understanding of the settlement’s inhabitation

Last fieldwork campaign at El Castillon revealed how dwelling was between the 5th and the 6th centuries.

The seventh campaign of excavation at the site located in the nearby of Santa Eulalia de Tabara (a small hamlet in the province of Zamora, Castilla y Leon) has been carried out this summer 2014. The results have helped to understand the urban development experimented in the settlement about the 5th and 6th centuries. Archaeologists have unearthed several dwelling structures which evolved along the time from one use to another, allowing scholars to reinterpret their functions.
