The Palaeogenomics study conducted by the Human Evolutionary Biology group of the Faculty of Science and Technology, led by Concepción de la Rua, in collaboration with researchers in Sweden, the Netherlands and Romania, has made it possible to retrieve the complete sequence of the mitogenome of the Pestera Muierii woman(PM1)using two teeth. This mitochondrial genome corresponds to the now disappeared U6 basal lineage, and it is from this lineage that the U6 lineages, now existing mainly in the populations of the north of Africa, descend from.

In contradiction to the long-standing idea that larger planets take longer to form, U.S. astronomers today announced the discovery of a giant planet in close orbit around a star so young that it still retains a disk of circumstellar gas and dust.

An area of low pressure designated as System 90L, located in the Atlantic Ocean between Bermuda and the Bahamas is being monitored today for possible development into a tropical or subtropical cyclone. The Global Precipitation Measurement (GPM) mission core observatory satellite flew over the developing low pressure area on May 26, 2016 at 0932 UTC (5:30 a.m. EDT).
Shower activity has increased in the area. NOAA's National Hurricane Center (NHC) has advised interests along the southeastern coast of United States to monitor the progress of this low.

An international team of scientists has identified a common phenomenon in galaxies that could explain why huge numbers of them turn into cosmic graveyards.

MADISON, Wis. -- With spring now fully sprung, a new study by University of Wisconsin-Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners' ears, but that tune could be alarming to some native and migratory birds and bugs.

A new model developed by University of Rochester researchers could offer a new explanation as to how cracks on icy moons, such as Pluto's Charon, formed.
Until now, it was thought that the cracks were the result of geodynamical processes, such as plate tectonics, but the models run by Alice Quillen and her collaborators suggest that a close encounter with another body might have been the cause.

Radar measurements of Mars' polar ice caps reveal that the mostly dry, dusty planet is emerging from an ice age, following multiple rounds of climate change. Understanding the Martian climate will help determine when the planet was habitable in the past, how that changed, and may inform studies of climate change on Earth. Models have suggested that Mars has undergone ice ages in the past, but empirical data to confirm this has been sparse.

San Antonio, Texas -- May 26, 2016 -- Using radar data collected by NASA's Mars Reconnaissance Orbiter, a Southwest Research Institute-led team found evidence of an ice age recorded in the polar deposits of Mars. Ice ages on Mars are driven by processes similar to those responsible for ice ages on Earth, that is, long-term cyclical changes in the planet's orbit and tilt, which affect the amount of solar radiation it receives at each latitude.

Meerkats live in groups of up to 50 individuals, yet a single dominant pair will almost completely monopolise reproduction, while subordinates help to raise offspring through feeding and babysitting. Since only a small minority of individuals ever get to be dominants, competition for the breeding role is intense in both sexes and females are unusually aggressive to each other.

New research has revealed that fewer than predicted planets may be capable of harbouring life because their atmospheres keep them too hot.
When looking for planets that could harbour life, scientists look for planets in the 'habitable zones' around their stars - at the right distance from the stars to allow water to exist in liquid form. Traditionally, this search has focused on looking for planets orbiting stars like our Sun, in a similar way to Earth.
