Long-term tropical lizard decline linked to El Niño events

Natural ups and downs in the numbers of a tropical lizard species may be a result of global-scale El Niño events, according to a unique 40-year census conducted at the Smithsonian Tropical Research Institute in Panama

Natural ups and downs in the numbers of a tropical lizard species may be a result of global-scale El Niño events, according to a unique 40-year census conducted at the Smithsonian Tropical Research Institute in Panama. The estimated number of lizards on Barro Colorado Island has declined dramatically: In the last decade, census takers recorded only about 35 percent of the number of lizards, Anolis apletophallus, present during 1970-1980.

Progress in the study of the mitochondrial changes that occur with cancer

Researchers of the MitoXT Laboratory of the Neuroscience and Cell Biology Centre of the University of Coimbra are studying in depth how these changes may act as a therapeutic objective

Mitochondria are organelles that play an essential role in the cell. As well as being responsible for cellular respiration, they regulate death, the signalling of calcium, the synthesis of steroids, redox homeostasis (the reduction-oxidation reaction), and cell ions. Researchers of the MitoXT (Mitochondrial Toxicology and Experimental Therapeutics) Laboratory of the Neuroscience and Cell Biology Centre of the University of Coimbra in Portugal are working essentially on assessing mitochondrial changes in cancer.

Conicet researchers contribute to the knowledge on the regulation mechanisms of genes in eukaryotic organisms

In the future, these findings may be applied in agricultural and health issues to provide for creative solutions

Marcelo Yanovsky, researcher of the Conicet at the Instituto de Investigaciones Bioquímicas de Buenos Aires (IIBBA, CONICET-IIBFL) [Institute of Biochemical Research of Buenos Aires] and his lab team proved that LSM genes, which are present in all eukaryotic organisms ranging from yeast to humans, are controlled by a biological clock. Experts affirm that faults in its function alter circadian rhythms not only in the plant world but also in in vitro culture human cells.

Test can help plan therapy against rheumatoid arthritis

The findings were recently published in 'Proceedings of the National Academy of Sciences (PNAS)'

A test developed and patented by researchers in Ribeirão Preto, São Paulo State, Brazil, makes it possible to identify patients with rheumatoid arthritis who will not respond to the drug methotrexate (MTX) even before treatment has begun. MTX is considered the gold standard for combating the disease.

Smithsonian scientists explain spread of chikungunya vector tropical disease

Chikungunya causes fever, fatigue and joint swelling and is transmitted by the Asian tiger mosquito, ‘Aedes albopictus’

The tropical disease chikungunya began twisting Western tongues last July when the first locally transmitted case was reported in Florida. Spotted in the Caribbean in 2013, the disease spread explosively throughout the Americas last year. Chikungunya’s arrival in Panama prompted Smithsonian Tropical Research Institute (STRI) scientists to examine how human activity spreads its mosquito vector and the serious implications this has for disease ecology everywhere.

Argentine and german scientists found how a protein regulates the growth of some type of tumours

This finding would be used to develop localized therapies

In 2007, the team coordinated by Eduardo Arzt, CONICET senior researcher and professor at the Faculty of Exact and Natural Sciences of the University of Buenos Aires, identified for the first time the genetic code for RSUME protein and discovered that one of the roles of this molecule is to modify proteins to assign new roles, for instance the ability to mediate the cell’s response to external factors such as lack of oxygen, etc.

A study at the Universidad Carlos III de Madrid (UC3M) analyzes how social networks were used between the attacks on March 11, 2004 (11M) and the demonstration in the Puerta del Sol on May 15th (15M). “On the tragic day of 11-M, there arose doubts about what the traditional media was saying,” explained Eva Herrero, researcher in the UC3M Department of Journalism and Audiovisual Communication. The response to this doubt resulted in “a call through SMS to demand explanations from the politicians,” said Herrero. At the same time, she observed that “that day might be the starting point for the creation of an alternative agenda outside of newsrooms by citizens.

Mysterious mangrove moth

Bloggers in Bocas Del Toro drew attention to an island in Dolphin Bay near Bocatorito where red mangrove trees are drying out

Earlier this month, bloggers in Bocas Del Toro drew attention to an island in Dolphin Bay near Bocatorito where red mangrove trees are drying out. “I watched this particular mangrove go from green to brown in a matter of two weeks,” wrote sailboat captain Steven Guling in a note to STRI staff scientist Andrew Altieri. “One local kid who often comes to my boat while in Dolphin Bay was describing a worm with teeth but at the time it wasn't quite that clear and I thought he was referring to something in the water.”

ALMA and VLT probe an Old-looking Galaxy in a Young Universe

A team of astronomers, led by Darach Watson from the University of Copenhagen, used ALMA and theVLT's X-shooter instrument to observe one of the youngest and most remote galaxies ever found

One of the most distant galaxies ever observed has provided astronomers with the first detection of dust in such a remote star-forming system and tantalizing evidence for the rapid evolution of galaxies after the Big Bang. The new observations have used the Atacama Large Millimeter/submillimeter Array (ALMA) to pick up the faint glow from cold dust in the galaxy A1689-zD1 and used ESO's Very Large Telescope (VLT) to measure its distance.

The increase in the concentration of dissolved nutrients stimulates plant litter decomposition in streams

Researchers from Portugal, France, the United Kingdom and the United States have published a review of the scientific literature that assessed the response of plant litter decomposition to the increase in the concentration of nutrients in streams

The decomposition of plant litter is a fundamental process in forest streams. These small streams constitute the majority of watercourses in many river basins and are usually shaded by the surrounding vegetation. The lack of sunlight to these streams limits the primary production or vegetal production, which is the process that underlies the food chains in many systems such as forests, grasslands, lakes or the open sea. However, the surrounding vegetation is a source of plant remains, especially leaf litter, to these streams. This litter is decomposed by micro-organisms and invertebrates, which by their actions lead to the availability of carbon and nutrients and their incorporation into the food webs.

Molybdenum, a promising metal for decontaminating water

Phenol is a residue of industrial phenolic resin production and is used in foundry, coatings, filters, abrasives and adhesives, among others

In Colombia only 30% of wastewaters are treated. Using solar photocatalysis, a chemical process in which the only source of energy is the sun, water quality could be improved. This method to eliminate organic compounds was used by UNal-Manizales Chemical Engineer Sandra Milena López Zamora, to search for the ideal material to help improve the photocatalytic properties of titanium dioxide (TiO2), very used in this type of procedures due to its high solar energy conversion efficiency.

STRI scientists Javier Ballesteros, project coordinator, and Ernesto Bonadies, a project intern, followed-up by checking the tomograms against visible fungal damage in the tree stumps

A towering tropical tree may look perfectly healthy on the outside but be in danger of collapse from fungal decay on the inside. Fungal diseases are part of the natural cycle of birth and death in the forest. In a city prone to gusty storms, however, infected trees threaten people, vehicles, and structures. How can municipal authorities identify dangerous trees?
