ALMA studies infant sun-like solar system to try and catch the wind

These winds could have important implications for planet formation

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have studied a special kind of young star, a T Tauri star, to understand why some have disks that glow weirdly in infrared light while others shine in a more predictable fashion. The answer, researchers speculate, may be due to differences in the wind around these stars.

Violent origins of elliptical galaxies

New observations explain why Milky Way-like galaxies are so common in the Universe

For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using ALMA and a host of other radio telescopes have found direct evidence that merging galaxies can instead form pancake galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe.

Slow-moving shallows put the heat on Bocas Coral

Some coral species may adapt to higher temperatures. The study’s models predict that areas flushed by cooler water will have a higher chance at surviving well into the future

Snorkel-perfect coral reefs in the calm, mangrove-fringed waters of the Bocas Del Toro Archipelago are expected to be among the hardest hit by warmer temperatures that lead to coral bleaching and mortality, a new study finds. These shallows in Panama’s Caribbean are characterized by low water flow, allowing water to reach precariously high sea surface temperature (SST) when compared to areas with greater water movement.

Genetic diversity of mandarin orange discovered

This result serves to determine if there are material duplicates in the studied bank

A UNal-Palmira and Regional Autonomous Corporation of Caldas (CORPOICA, for its Spanish acronym) study determined that there is an important genetic variability of this species, enabling its maintenance and preservation. Despite being a very much consumed fruit around the world the precise genome contribution of its ancestral species is unknown. This has turned it into a research target for different research groups around the world which hope to molecularly classify citric fruits.

From a fish’s point of view, the Caribbean Sea is really three different regions

New results from the Smithsonian published in the journal ‘PLOS ONE’

“Previously, the Greater Caribbean was considered to be one big homogenous region of the Tropical West Atlantic,” said Ross Roberson, staff scientist at the Smithsonian Tropical Research Institute in Panama. “According to our shorefish surveys, the Caribbean should really be considered to be three distinct provinces.”

Astronomers observe the inside of a star for the first time

Data obtained by the international team monitoring the phenomena on Eta Carinae, led by Augusto Damineli, professor at the IAG/USP, could validate or disprove existing theoretical models about the structure of large stars

Through a small telescope installed at the top of a mountain covered by banana trees between the southern Minas Gerais towns of Brazópolis and Piranguçu, a group of scientists has been monitoring a first-of-its-kind astronomic phenomenon whose peak is expected to occur within days: the opening of a hole in the surface of a giant star known as Eta Carinae, allowing discovery of the secrets inside.

Deforestation of Amazônia is increasing pollution in South American countries

Study indicates that smoke from fires in Amazon states migrates to Bolivia, Peru and Paraguay, raising the atmospheric pollution levels of these countries

The Amazon states of Pará, Rondônia, Amazonas and Acre have "exported" the smoke produced by burning to clear land to Bolivia, Peru and Paraguay and have contributed to increasing the levels of atmospheric pollution in these neighboring countries. Along with Mato Grosso, these four states have also registered the highest number of wildfires in South America.

Methods of Sherlock Holmes to get the best view yet of merging galaxies in distant Universe

Astronomers are now combining the power of many telescopes on Earth and in space with a vastly larger form of cosmic lens to study a case of vigorous star formation in the early Universe

Using the Atacama Large Millimeter/submillimeter Array (ALMA), and many other telescopes on the ground and in space, an international team of astronomers has obtained the best view yet of a collision that took place between two galaxies when the Universe was only half its current age. They enlisted the help of a galaxy-sized magnifying glass to reveal otherwise invisible detail. These new studies of the galaxy H-ATLAS J142935.3-002836 have shown that this complex and distant object looks like the well-known local galaxy collision, the Antennae Galaxies.

Brazilian plants may help to mitigate impact of climate change

Studying the genomes of heat- and drought-tolerant species (such as the pequi) from the semi-arid and Cerrado regions may contribute to the genetic improvement of crops such as soya, maize, rice and beans

The seriguela (Spondias purpurea) and umbuzeiro (Spondias tuberosa), trees commonly found in Brazil’s northeastern semi-arid region, and the Brazilian chestnut, native to the Cerrado, are part of a group of plants that could play an important role in agriculture by mitigating the consequences of climate change. They are among several Brazilian species that have enhanced adaptive capacity and are heat and drought tolerant.
