GMO Soybean Pollen Threatens Mexican Honey Sales

A Smithsonian researcher and colleagues helped rural farmers in Mexico to quantify the genetically modified organism (GMO) soybean pollen in honey samples rejected for sale in Germany

Mexico is the fourth largest honey producer and fifth largest honey exporter in the world. A Smithsonian researcher and colleagues helped rural farmers in Mexico to quantify the genetically modified organism (GMO) soybean pollen in honey samples rejected for sale in Germany. Their results appeared on Feb. 7 in the online journal, Scientific Reports.

Found a key process for methane gas formation

An international group of scientists, with the participation of The Institute of Natural Resources and Agrobiology of Salamanca (IRNASA, CSIC center), has discovered a regulatory key process in certain microorganisms which produce methane, the main ingredient of natural gas. This process is similar to the one that activates photosynthesis in plants and finding it in anaerobic microorganisms is an important change for the evolutionary biology. That is the reason why this work has been published at the prestigious scientific magazine Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Protoplanetary Disks ‘Bulge’ in Complex and Asymmetrical Ways

By comparing these results with other early ALMA observations, the researchers speculate that asymmetrical disks may be the norm and an essential step along the path to planet formation.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have studied two massive protoplanetary disks and discovered large-scale asymmetries in the way their dust is distributed.

ALMA Helps to Explain Massive Stars Mysterious Formation

The formation process of a massive star has been a long-standing problem

A research team led by Tomoya Hirota (National Astronomical Observatory of Japan: NAOJ) discovered a hot circumstellar disk around a massive protostar by using the Atacama Large Millimeter/Submillimeter Array (ALMA) and the VLBI Exploration of Radio Astrometry (VERA). The formation process of a massive star has been a long-standing problem. The research results favor disk accretion for the formation of massive stars, similar to the formation of low to intermediate mass stars such as the Sun.

Just as Wi-Fi routers replaced wires, LED light bulbs could replace wireless networks. UNal engineers are working on the possibility of transmitting data through visible light. As his UNal Telecommunications Engineering master’s thesis project, Germán Alfredo Chávarro proposed developing a basic Visible Light Communication (VLC) transmission system. This system would allow transmitting audio information using visible light communication.

Research carried out at the UNal- Bogotá Animal Learning and Behavior laboratory

Analysis performed on sexual behavior of quails showed that eliminating the stimuli, contrary of what was expected, increased the behavior. The research analyzed conduct learning using exercises which link stimuli to responses (just as human beings understand that turning a key opens a door), and emphasizing of the effects produced when stimuli are suspended.

Wastewater to be treated with bio additives

Researchers at the Tecnológico de Monterrey's Water Center for Latin America and the Caribbean have received a CONACYT grant to conduct research on optimizing wastewater treatment processes by using enzymes and fungi

In mainstream wastewater treatment, separating the sludge and the treated water is done by withdrawing less dense liquid from a solid or dense liquid, in a process known as decantation. However, very frequently the sludge does not have the necessary conditions to allow decanting, severely handicapping the effectiveness of a treatment plant's treatment process.

Adhesive bands will now be biodegradable and more effective against pain

Water helps the biofilm stick to the skin and at the same time degrade until it slowly disappears and the patient doesn’t need to take it off

Each time someone has a small injury they appeal to adhesive bands to protect the wound. Now researchers are raising the possibility of making an adhesive film which will speed up scar formation, reduce pain and bleeding. Furthermore this film was also conceived for protecting the environment after being used as it degradation is complete after use given its biodegradable components.

Enzymes seem to be essential in latent bacteria which produce tuberculosis

Tuberculosis sky-rocketed with HIV and currently is the most lethal infectious disease which produces more bacterial sourced deaths in the world.

The UNal Microbacteria Biochemistry and Molecular Biology Research Group (BBMM, for its Spanish acronym) was the first to research ATPase enzymes of the tuberculosis bacillus when nobody thought they were important. After the work of the BBMM group several United States and French research groups, such as the Pasteur Institute have become interested in these enzymes.

‘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.
