Scripps research scientists identify infertility molecule

... before having their first child. In fact, the CDC reports that in 2002, the latest year for which the statistics are available, more than 100,000 women over the age of 40 gave birth. This was the first time that this number topped 100,000 in a given year. The success of these older-than-traditional women a...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...iate toxic effects to the nervous system, and some reports have implicated them as possible endocrine disruptors. Many of these compounds cannot be destroyed by existing means. The catalyst, one of a family of catalysts called Fe-TAMLs (TAML stands for tetra-amido macrocyclic ligand), works with hydrogen pe...

New insights into how Huntington's disease attacks the brain

FSU scientist warns North Atlantic right whale facing extinction

.... Only 17 percent of all mortality is detected, so reports of dead whales represent only a small fraction of actual deaths. "Recent increases in calving rates, an average of 23 annually over the last five years, are inadequate to overcome this level of mortality," the paper states. "Without changes in the m...
