Rutgers geneticists have reported groundbreaking research on the genetics of fertility. They have discovered two genes, aptly named egg-1 and egg-2, required for fertilization to take place. The proteins encoded by these genes are similar to low density lipoprotein (LDL) receptors, known from cholesterol and fat metabolism but never before specifically implicated in fertilization.
One in six couples is experiencing fertility problems worldwide, and people are asking why. This is a question of great medical, social and economic importance – one that cannot be answered until the process of fertilization is more fully understood.
A team led by Andrew Singson, an assistant professor and Pavan Kadandale, a graduate student in the Singson lab at the Waksman Institute of Microbiology at Rutgers, The State University of New Jersey, has taken a new and productive approach in this quest. The researchers found that in the absence of these two genes, the vital process of fertilization came to a halt. "What we learn in studying fertilization is not only important for this event, but also for the functioning of other cells in our bodies and for understanding many of those processes," Singson said.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
