Tracing the steps of a giant

Argentine and British researchers digitally recreated the gait of the Argentinosaurus huinculensis, a forty metres long and eighty tonnes dinosaur

How could these animals move around in spite of their size? This is the question that a group of scientists of different countries tried to answer. Among them was Rodolfo Coria, Independent researcher of CONICET at theInstituteofPaleobiologyand Geology (IIPByG, UNRN).

Experts from around the world review more than 1,300 observation proposals for ALMA

78 world-leading experts in their area of astronomical research are meeting near Toronto, Canada

This week, 78 world-leading experts in their area of astronomical research are meeting near Toronto, Canada, to scientifically evaluate the 1,381 proposals received for Cycle 2 Early Science observations with the radio telescope, which represent a demand of more than 7.000 hours of observation. In this cycle, about 1,700 hours of observation are to be distributed among the selected proposals.

‘Death Stars’ in Orion Blast Planets before They Even Form

A team of astronomers from Canada and the United States has used the Atacama Large Millimeter/submillimeter Array (ALMA) to study the often deadly relationship between highly luminous O-type stars and nearby protostars in the Orion Nebula

The Orion Nebula is home to hundreds of young stars and even younger protostars known as proplyds. Many of these nascent systems will go on to develop planets, while others will have their planet-forming dust and gas blasted away by the fierce ultraviolet radiation emitted by massive O-type stars that lurk nearby.

Worn out paper money could be used for decontamination

In Colombia high-denomination bills have a useful life which ranges from one to two years and four months

Worn out bills will now have a second useful life. They may be turned into material which would help decontaminate wastewater and remove pollutants from the environment. When a bill deteriorates it is destroyed in high speed machines which chop it into small confetti-size pieces. This waste is handled differently in each country; although common practice is to dispose it in sanitary landfills or incineration.

ALMA sees wreckage of comet collisions in nearby solar system

The new results are published today in the journal 'Science'

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in northern Chile have today announced the discovery of an unexpected clump of carbon monoxide gas in the dusty disc around the star Beta Pictoris. This is a surprise, as such gas is expected to be rapidly destroyed by the star’s UV radiation. Something — probably frequent collisions between small, icy objects such as comets — must be causing the gas to be continuously replenished. The new results are published today in the journal Science.

New study suggests that people of African descent are more resistant to DHF

Researchers from the University of Antioquia have revealed a putative role for the genetic ancestry in the development of dengue hemorrhagic fever. The study suggests that people of predominantly African ancestry are more resistant to DHF infection

Juan Camilo Chacón, 25, who has a MA in Biology from the University of Antioquia, is the co-author of this groundbreaking study. Chacón's brothers died from cystic fibrosis, an incurable hereditary disorder, which caused him to become interested in genetics. Chacón has a master’s degree in biology and is currently pursuing a PhD in Evolutionary Genetics at University College London (UCL). He is also a member of the Molecular Genetics Research Group (GENMOL) at the University of Antioquia. In addition, Chacón received honorable mention from the National Academy of Medicine in 2013 for his research proposal The relationship between ancestral genetic composition and dengue fever in Colombian population samples, which he wrote as part of his master’s thesis while finishing his MSc in Biology at the University of Antioquia.

Risky ripples: Frog´s love song may summon kiss of death

This project, published in Science, was made possible with funds from STRI, the U.S. National Science Foundation and the Netherlands Organization for Scientific Research

Male Túngara frogs call from puddles to attract females. The production of the call incidentally creates ripples that spread across the water. Researchers at the Smithsonian Tropical Research Institute in Panama revealed that these ripples are used by other male frogs to assess the level of competition in the puddle. Unfortunately for the frogs, their main predator, the frog-eating bat, senses the ripples too, making the frogs easier targets.

Pioneers in the implementation of superselective intraocular chemotherapy

They improved a technique that increases the chances of sight preservation in retinoblastoma, which represents 15% of cancer cases in children under one year

An interdisciplinary team of scientists from different institutions and specializations managed to develop and apply in Argentina a superselective infusion technique of intraocular chemotherapy for treatment of advanced retinoblastoma. The availability of this therapy at the J.P. Garrahan Pediatric Hospital makes it the third institute worldwide in terms of the number of treated patients and a pioneer in the implementation of this technique in Latin America.

Introduction through Panama Canal? Pacific jingle shell found in caribbean

The 50-mile (80-kilometer) Panama Canal has been transited more than one million times since its inauguration almost 100 years ago, potentially providing organisms with endless opportunities to stow away on the vessels of international trade

In 2009 a team of STRI researchers raised sea-critter covered PVC plates from a marina in Limón Bay on Panama’s Caribbean coast and found something unexpected: Peruvian jingle shells, bivalves native to the Pacific. In subsequent years the small creature, known for its thin and iridescent shells, appeared on settlement plates in other locations around the Atlantic side of the Panama Canal.

Smart shock-absorbers to avert accidents, on and off the road

Car accidents due to damaged roads or industrial accidents due to failure control flaws could be a thing of the past thanks to Tecnológico de Monterrey researchers who have created smart shock absorber and surveillance systems

According to the WHO, over 2% of world deaths are related to car accidents caused by drivers losing control at high speeds over rough roads. These accidents could be avoided by an automatic monitoring and diagnostic of mechanical system malfunction.

Microorganisms could help seal cement cracks

In the near future researchers will embark on tests such as adding bacteria to cement mixtures and making cement cubes in order to test them against cubes without calcite

Isolating microorganisms which form calcite (calcium carbonate crystals), scientists are researching producing material which could provide greater durability to cement. These types of microorganisms could help seal micro-fissures in the internal structure of bio-cement in an eco-friendly manner. When cement mixture is prepared small air-filled voids remain.

Astronomers discovered a drastic chemical change in the birth of a planetary system

As a result of the observations, Sakai et al. have found that carbon-chain molecules and their related species such as cyclic-C3H2 almost completely disappear in the gas phase

So far, the interstellar matter was believed to be smoothly brought into a gas disk forming a planetary system as it is. Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team led by Dr. Nami Sakai has been able to observe a drastic chemical change associated with the formation of the disk around the young protostar L1527 in the Taurus molecular cloud.

Guillermo Mazzolini Rizzo, hepatologist and CONICET independent researcher at the Gene Therapy Laboratory of the School of Biomedical Sciences of the Austral University in Buenos Aires, has been studying for ten years the role of the osteonectin protein, or SPARC, in the hepatic fibrosis, a process that progressively replaces the hepatic tissue with fibrous tissue, caused by different pathologies, and thus it could lead to cirrhosis.
