Halley’s Comet. Credit: NASA Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA. They found that organic compounds, called amino nitriles, the molecular precursors to amino acids, were able to use molecules present in interstellar ice to trigger

The sampling site used to isolate the methanotroph, namely a geothermal field in Rotokawa, New Zealand.

Soil bacteria

A new map of the thickness of Mars’ crust shows less variation between thicker regions (red) and thinner regions (blue), compared to earlier mapping. This view is centered on Valles Marineris, with the Tharsis Montes near the terminator to its west. The map is based on modeling of the Red Planet’s gravity field by scientists

Artist’s impression of Anatoliadelphys maasae.

The findings, by Dr Robin Beck from the University of Salford in the UK and Dr Murat Maga, of the University of Washington

X-ray microtomography image of trace fossil in sediment. Credit: Luke Parry – University of Bristol Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth. The international team, including palaeontologist from The University of Manchester, found a new set of

A polynya, or an opening in the sea ice, was present in the Southern Ocean in the 1970s. This image shows the sea ice concentration averaged over three September months 1974-1976 during the Weddell Polynya, made with data from the NIMBUS-V satellite from the National Snow Ice Data Center.

This image shows a self-reconfiguring modular robots scheme. Credit: Iridia Lab ULB Researchers at the Université libre de Bruxelles have developed self-reconfiguring modular robots that can merge, split and even self-heal while retaining full sensorimotor control. The work may take us closer to producing robots that can autonomously change their size, shape and function. The

Pluto’s first official surface-feature names are marked on this map, compiled from images and data gathered by NASA’s New Horizons spacecraft during its flight through the Pluto system in 2015. Credit: NASA/JHUAPL/SwRI/Ross Beyer The IAU has assigned names to fourteen geological features on the surface of Pluto. The names pay homage to the underworld mythology,

The footprints were discovered by Gerard Gierlinski (1st author of the study) by chance when he was on holiday on Crete in 2002. Gierlinski, a paleontologist at the Polish Geological Institute specialized in footprints, identified the footprints as mammal but did not interpret them further at the time. In 2010 he returned to the site
