Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface, according to researchers who have been carrying out the painstaking task of analysing individual particles of Martian soil.

Call for Media: briefing on new results from ESA Planck mission - - Media representatives are invited to a briefing on new observations of the Milky Way and other galaxies by ESA's Planck mission.

Luminescence of CdSe/CuS nanocrystals prepared by cation-exchange. On the left are crystals prior to purification, on the right are the same nanocrystals after impurities have been removed.

New research from the University of Bristol may disprove a long-standing conjecture made by one of the founders of quantum information science: that quantum states featuring 'positive partial transpose', a particular symmetry under time-reversal, can never lead to nonlocality.

ANN ARBOR, Mich. - Why is the universe magnetized? It's a question scientists have been asking for decades.

ANN ARBOR, Mich. - Astronomers have detected a mysterious ring of carbon monoxide gas around the young star V1052 Cen, which is about 700 light years away in the southern constellation Centaurus.

Wonder material graphene has been touted as the next silicon, with one major problem – it is too conductive to be used in computer chips.

Researchers at Yale University have developed a new way of exposing the atomic attachments that keep complex molecules in precise alignment.

Researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft.

Scientists have used a laser to create magnetic fields similar to those thought to be involved in the formation of the first galaxies; findings that could help to solve the riddle of how the Universe got its magnetism.

Wild early lives of today's most massive galaxies revealed - Astronomers from Durham University have helped find the strongest link so far between the most powerful bursts of star formation in the early Universe and the most massive galaxies found today.

Discovery could offer clues on the nature of dark matter. In a discovery announced Jan. 18, an international team of researchers has found a dark dwarf galaxy about 10 billion light years from Earth.
