ALMA witnesses assembly of galaxies in the early universe for the first time

By combining the new ALMA observations with computer simulations, it has been possible to understand in detail key processes occurring within the first galaxies

The Atacama Large Millimeter/submillimeter Array (ALMA) has been used to detect the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronomers to start to see how the first galaxies were built up and how they cleared the cosmic fog during the era of reionization. This is the first time that such galaxies are seen as more than just faint blobs.

The Captain fish will repopulate the Cundinamarca-Boyacá Provinces high plateau water bodies

UNal researchers are currently working on a repopulation plan on the water sources of the Cundinamarca-Boyacá Provinces high plateau from a sample of 90 species gathered in the high basin of the Bogotá River

The captain fish (Eremophilus mutisii) is a solitary, calm and endemic fish which was lost from the memory of Colombians, especially the inhabitants of the Savannah of Bogotá. The tributaries of the Negro, Frío, Chicú, Balsillas, Juan Amarillo, Fucha, Tunjuelo and Soacha Rivers were formerly the natural habitat of the cold water guardian and was one of the main food sources of the region.

Glass ceramic material is effective for treatment of dentin hypersensitivity

The material is also being tested in ocular implants and artificial middle ear bones, among other applications

Researchers at the University of São Paulo’s Dentistry School in Ribeirão Preto, São Paulo State, Brazil, are testing a glass-ceramic material for use in the treatment of dentin hypersensitivity. This condition, which manifests as acute pain in response to hot or cold drinks and food, arises from exposed dentin surfaces due to receding gums. Dentin is the tissue that forms the bulk of a tooth.

Nanometric sensor designed to detect herbicides can help diagnose multiple sclerosis

The nanobiosensor consists of a silicon nitride or silicon nanoprobe with a molecular-scale elastic constant and a nanotip coupled to an enzyme, protein or other molecule

The early diagnosis of certain types of cancer, as well as nervous system diseases such as multiple sclerosis and neuromyelitis optica, may soon be facilitated by the use of a new detection device: a nanometric sensor capable of identifying biomarkers of these pathological conditions. The nanobiosensor was developed at the Federal University of São Carlos (UFSCar), Sorocaba, in partnership with the São Paulo Federal Institute of Education, Science & Technology (IFSP), Itapetininga, São Paulo State, Brazil. It was originally designed to detect herbicides, heavy metals and other pollutants. An article about the nanobiosensor has just been published as a cover feature by IEEE Sensors Journal.

ALMA detects first traces of carbon ‘smog’ permeating interstellar atmospheres of early galaxies

ALMA, with its unprecedented sensitivity, was able to detect the faint but ubiquitous millimeter 'glow' of ionized carbon in the interstellar atmospheres of nine very distant

Astronomers study the elements scattered between the stars to learn about the internal workings of galaxies, their motion and chemistry. To date, however, attempts to detect the telltale radio signature of carbon in the very early Universe have been thwarted, perhaps – as some have speculated – by the need to allow a few billion years more for stars to manufacture sufficient quantities to be observed across such vast cosmic distances.

A new method transforms industrial waste into cement

Researchers from the University of Aveiro are developing a system to reduce the ecological footprint of one of the industries with most CO2 emissions in the world

A group of the Research Centre for Ceramic Materials and Compounds (Centro de Investigação em Materiais Cerâmicos e Compósitos, CICECO) of the University of Aveiro has produced a new type of cement based on industrial waste. This new system, which has only so far been tested experimentally, needs less energy and uses only waste, which means that its implementation would reduce the environmental impact of the cement industry.

Shiitake antipasto has anti-carcinogenic and nutritional properties

In replacing fish, chicken or meat protein for the ones in this Japanese fungus, UNal researchers discovered not only its nutritional qualities but that it also helps diminish cholesterol and glycaemia levels

The shiitake fungus (Lentinula edodes) has a fruit body known as the cap and comparatively larger than the edible mushroom cap. It is brown and has great nutritional and medicinal potential and very sought for its texture and flavor. However its stem is not consumed and disposed due to its fibrous composition, which is often rejected by consumers.

ALMA weighs supermassive black hole at center of distant spiral galaxy

Currently, astronomers use several methods to derive the mass of a supermassive black hole; the technique used typically depends on the type of galaxy being observed

Supermassive black holes lurk at the center of virtually every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun. Determining just how massive, however, has been daunting, especially for spiral galaxies and their closely related cousins barred spirals. In a new proof-of-concept observation, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have measured the mass of the supermassive black hole at the center of NGC 1097 -- a barred spiral galaxy located approximately 45 million light-years away in the direction of the constellation Fornax.
