Good Vibrations for Catalytic Chemistry

March 12, 2014 2:41 pm | by Univ. of Utah | News | Comments

Chemists have discovered how vibrations in chemical bonds can be used to predict chemical reactions and thus design better catalysts to speed reactions that make medicines, industrial products and new materials.                                        

Human Parasites Interact Via Shared Food Sources

March 12, 2014 2:23 pm | by Univ. of Zurich | News | Comments

Humans are often infected by parasites, sometimes even several species at a time. Such co-infections are more difficult to treat if the parasites interact with each other. An international team has compiled a list of the numerous possibilities as to how parasites can interact: they are most likely to do so indirectly via the food source they share.

Crowdsourced Rain Maps Sandy’s Evolution

March 12, 2014 12:00 pm | by Univ. of Utah | News | Comments

A unique method to collect rain water samples during Hurricane Sandy has revealed the storm’s chemical “signature” with a new level of detail. The technique may also lead to weather model advances that will ultimately improve storm prediction.

Turing Proven Correct 60 Years After Death

March 11, 2014 12:00 pm | by Brandeis Univ. | News | Comments

Alan Turing’s accomplishments in computer science are well known, but lesser known is his impact on biology and chemistry. Turing proposed a theory of morphogenesis, the process by which identical cells differentiate. Now, 60 years after Turing’s death, researchers have provided the first experimental evidence that validates Turing’s theory in cell-like structures.

Research Finds Mercury from in-ground Wastewater Disposal

March 11, 2014 12:00 pm | by Woods Hole Oceanographic Institution | News | Comments

As towns across Cape Cod struggle with problems stemming from septic systems, a recent study by a biogeochemist focused on one specific toxic by-product: mercury. In a study of local groundwater, he found that microbial action on wastewater transforms it into more mobile, more toxic forms of the element.
