An article published in the prestigious science magazine Nature Geoscience yesterday shows that the period towards the end of the ice age was engraved by extreme and short-lived variations, which finally terminated the ice age.
Research scientists in Bonn have succeeded in deriving so-called brain stem cells from human embryonic stem cells.
The U.S. Food and Drug Administration says the list of companies recalling possibly contaminated products containing peanuts is still growing. The FDA said the Peanut Corp.
In the Southern Indian Ocean, climate change is leading to stronger winds, which mix waters, bringing CO2 up from the ocean depths to the surface.
A major science conference has heard that alien life may be thriving right here on Earth.
The paper published in the Journal of the American Chemical Society (JACS) by a team led by professor Francesc Illas of the UBâ€™s Department of Physical Chemistry and director of the Laboratory of Computational Materials Science (CMSL) will help to broaden our understanding of the nature of superconducting materials and of the origin of the superconductivity phenomenon in high critical temperature materials.
A researcher said Monday that scientists have found fossil remains of an omnivorous dinosaur in Argentina, a missing link to the carnivores.
Researchers say a new facility opening later this year at Britain's Diamond Light Source synchrotron may revolutionize science. Officials said the powerful new experimental station called the Joint Engineering, Environmental and Processing beamline will carry out experiments in a variety of scientific areas, including biology and physical and chemical science. The versatility of JEEP will open up exciting new opportunities in many fields of science due to its extremely high flux, high energy X-ray beam and its two complementary experimental areas, said Michael Drakopoulos, principal scientist at the facility in Chilton, England. Diamond generates extremely intense pin-point beams of synchrotron light of exceptional quality, including x-rays, ultra-violet and infrared, said officials.
The argument over whether an outcrop of rock in South West Greenland contains the earliest known traces of life on Earth has been reignited, in a study to be published in the Journal of the Geological Society on 23 February.
