Nearby Universe's 'Cosmic Fog' Measured
21 января 2013

Researchers from the Laboratoire Leprince-Ringuet (CNRS/École Polytechnique) have carried out the first measurement of the intensity of the diffuse extragalactic background light in the nearby Universe, a fog of photons that has filled the Universe ever since its formation. Using some of the brightest gamma-ray sources in the southern hemisphere, the study was carried out using measurements performed by the HESS (1) telescope array, located in Namibia and involving CNRS and CEA.

One Form of Neuron Turned Into Another in Brain
22 января 2013

A new finding by Harvard stem cell biologists turns one of the basics of neurobiology on its head — demonstrating that it is possible to turn one type of already differentiated neuron into another within the brain.

New Evidence Indicates Auroras Occur Outside Our Solar System
23 января 2013

Auroras occur on several planets within our solar system, and the brightest - on Jupiter – are 100 times brighter than those on Earth. However, no auroras have yet been observed beyond Neptune. A new study led by University of Leicester lecturer Dr Jonathan Nichols has shown that processes strikingly similar to those which power Jupiter’s auroras could be responsible for radio emissions detected from a number of objects outside our solar system. In addition, the radio emissions are powerful enough to be detectable across interstellar distances – meaning that auroras could provide an effective way of observing new objects outside our solar system.

3-D Printing Breakthrough With Human Embryonic Stem Cells
6 февраля 2013

It is hoped that this breakthrough, which has been published Feb. 5 in the journal Biofabrication, will allow three-dimensional tissues and structures to be created using hESCs, which could, amongst other things, speed up and improve the process of drug testing.

Does Probability Come from Quantum Physics?
7 февраля 2013

But a new paper by physics professor Andreas Albrecht and graduate student Dan Phillips at the University of California, Davis, makes the case that these quantum fluctuations actually are responsible for the probability of all actions, with far-reaching implications for theories of the universe.

First Migration from Africa Less Than 95,000 Years Ago: Ancient Hunter-Gatherer DNA Challenges Theory of Early Out-Of-Africa Migrations
25 марта 2013

In particular these measurements have made geneticists think again about key dates in human evolution, like when modern non-Africans split from modern Africans. The recent measurements push back the best estimates of these dates by up to a factor of two. Now, however an international team led by researchers at the University of Tübingen and the Max Planck Institute for Evolutionary Anthropology in Leipzig, present results that point again to the more recent dates. The new study is published in Current Biology.

Dad's Life Stress Exposure Leaves Mark On Sperm, Can Affect Offspring Brain Development
14 июня 2013

While environmental challenges, like diet, drug abuse, and chronic stress, felt by mothers during pregnancy have been shown to affect offspring neurodevelopment and increase the risk for certain diseases, dad's influence on his children are less well understood. The effects of lifelong exposures to dad on children are even more out of reach.
