ALMA Witness Intergalactic Deluge Feeding a Black Hole

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has witnessed a cosmic weather event that has never been seen before

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has witnessed a cosmic weather event that has never been seen before – a cluster of towering intergalactic gas clouds raining in on the supermassive black hole at the center of a huge galaxy one billion light-years from Earth. The results will appear in the journal Nature on June 9, 2016.

Using a reverse paint-by-numbers approach, scientists have located another gene that controls the brilliant patterning of Heliconius butterfly wings

Using a reverse paint-by-numbers approach, scientists have located another gene that controls the brilliant patterning of Heliconius butterfly wings. Led by former Smithsonian Tropical Research Institute (STRI) fellow Nicola Nadeau, the researchers identified variations in the gene that correspond to wing color and pattern variation in three different Heliconius species. Published in Nature, June 2016, the discovery puts scientists a step closer to unlocking the code responsible for diversity and evolution in butterflies and moths.

A research project to improve the laws regarding disability

Madrid Sin Barreras

Six Madrid universities, led by Universidad Carlos III de Madrid (UC3M), are carrying out the research project “Madrid Sin Barreras” (Barrier-free Madrid) to promote the social inclusion of persons with disabilities. For that purpose, they are analyzing the laws governing accessibility in education, employment, mobility and participation, among other areas, with the goal of improving these regulations.

2016 BIO.IBEROAMÉRICA claims the Iberoamerican scientific heritage in its opening

The keynote lecture of Dr. Tejal Desai, an expert in nanotechnology based therapies , serves as starting point to a outstanding programme

The American researcher Tejal Desai was in charge of the opening lecture of BIO.IBEROAMÉRICA 2016. Intengrando Conteinentes'. The conference started today with an official ceremony, led by the rector of the University of Salamanca, Daniel Hernandez Ruipérez, who wanted to highlight during his intervention the close historical links between Salamanca´s academic institution , who turns 800 years in 2018, and the Latin America region. Ruiperez also expressed his wish that this anniversary would serve as an incentive to create a common university system throughout Latin America.

Discovering How Cyanobacteria Form Patterns for Nitrogen Fixation

These microorganisms are fundamental to life on Earth because they produce much of the oxygen in our planet, and convert nitrogen into chemical forms which can be used by any life form

Almost all the oxygen in the atmosphere today was produced by cyanobacteria 3,000 million years ago; cyanobacteria continue to produce between 20% and 30% of the photosynthetic activity on Earth. Furthermore, they perform additional vital tasks: along with other microorganisms called Archaea, they are the only living beings able to convert nitrogen from the atmosphere into chemical forms which can be used by any life form. According to one of the authors of the research, Saúl Ares of Grupo Interdisciplinar de Sistemas Complejos (GISC; Interdisciplinary Complex Systems Group) at UC3M. "Without cyanobacteria, neither human beings nor any other complex living organisms could survive on Earth, because we would not have oxygen to breathe or nitrogen with which to build complex molecules like DNA and the proteins in our bodies".

Mangrove decline through the ages in Central and South America

a new study looks to the past to provide conservation lessons for this essential ecosystem

As deforestation erases the thin, green line of mangrove forests along tropical shores, a new study looks to the past to provide conservation lessons for this essential ecosystem. Scientists from Colombia’s Talking Oceans Foundation, the University of York, U.K., and the Smithsonian in Panama document mangrove use and decline through the ages along the Pacific coastline of Costa Rica, Panama, Colombia and Ecuador.

ALMA Reveals Footprints of Baby Planets in a Gas Disk

New analysis of ALMA data for HL Tauri provides yet more firm evidence of baby planets around the star

New analysis of ALMA data for HL Tauri provides yet more firm evidence of baby planets around the star. Researchers uncovered two gaps in the gas disk around the star. The locations of these gaps in the gas match the locations of gaps in the dust found in the ALMA high resolution image taken in 2014. This discovery supports the idea that planets form in much shorter timescales than previously thought and prompts a reconsideration of alternative planet formation scenarios.

Cometary Belt around Distant Multi-Planet System Hints at Hidden or Wandering Planets

ALMA have made the first high-resolution image of the cometary belt around HR 8799

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made the first high-resolution image of the cometary belt (a region analogous to our own Kuiper belt) around HR 8799, the only star where multiple planets have been imaged directly. The shape of this dusty disk, particularly its inner edge, is surprisingly inconsistent with the orbits of the planets, suggesting that either they changed position over time or there is at least one more planet in the system yet to be discovered.

New species of fly parasitizes fungus-growing ant

The researchers note that this species is the first known of its family, 'Chloropidae', to parasitize ants

Larvae of the newly identified fly species Pseudogaurax paratolmos Wheeler grow up on a gory diet—the larvae of the fungus-growing ant Apterostigma dentigerum. The species is formally described by Cely González and co-authors working with Hermógenez Fernández-Marín, Smithsonian research associate and scientist at the Institute for Scientific Investigations and High-End Technology Services (INDICASAT-AIP). PhD student González discovered the new species in a larger survey of Apterostigma ant parasites.

Schizophrenia can already be diagnosed in the scientific sphere by mapping the brain with functional magnetic resonance imaging (fMRI) and data mining software. Now, researchers are working on a more detailed scrutiny of the main brain regions involved and are also attempting to detect possible reorganizations of cortical networks triggered by treatment with drugs.

To determine the actual mass of a supermassive black hole, astronomers must measure the strength of its gravitational pull on the stars and clouds of gas that swarm around it

Supermassive black holes, some weighing millions to billions of times the mass of the Sun, dominate the centers of their host galaxies. To determine the actual mass of a supermassive black hole, astronomers must measure the strength of its gravitational pull on the stars and clouds of gas that swarm around it.
