COLLEGE PARK, Md. — A research team including University of Maryland chemistry and biochemistry Professor Lyle Isaacs and University of Massachusetts Amherst chemist Vincent Rotello has demonstrated that they can deliver a dormant toxin into a specific site such as a tumor for anti-cancer therapy, then chemically trigger the toxin to de-cloak and attack from within. It holds promise as a complex and sophisticated synthetic, therapeutic drug delivery system for living cells. (more…)

If you think global warming is bad, 11 billion years ago the entire universe underwent what might be called universal warming. The consequence of that early heating was that fierce blasts of radiation from voracious black holes stunted the growth of some small galaxies for a stretch of 500 million years. (more…)

*MU scientist compares classical singing to traditional Indian singing to find speech disorder treatment*

COLUMBIA, Mo. – Hindustani singing, a North Indian traditional style of singing, and classical singing, such as the music of Puccini, Mozart and Wagner, vary greatly in technique and sound. Now, speech-language pathology researchers at the University of Missouri are comparing the two styles in hopes of finding a treatment for laryngeal tremors, a vocal disorder associated with many neurological disorders that can result in severe communication difficulties.

Palo Alto, CA — Geologists have found evidence that some 55 million years ago a river as big as the modern Colorado flowed through Arizona into Utah in the opposite direction from the present-day river. Writing in the October issue of the journal Geology, they have named this ancient northeastward-flowing river the California River, after its inferred source in the Mojave region of southern California.

COLUMBIA, Mo.– It might seem obvious that a dinosaur’s leg bone connects to the hip bone, but what came between the bones has been less obvious. Now, researchers at the University of Missouri and Ohio University have found that dinosaurs had thick layers of cartilage in their joints, which means they may have been considerably taller than previously thought. The study is being published this week in the journal PLoS-ONE (Public Library of Science). (more…)

WASHINGTON — Conditions at the edge of our solar system may be much more dynamic than previously thought, new observations suggest. Future exploration missions are expected to benefit in design and mission objectives from a better understanding of the changing conditions in this boundary region. (more…)
