Discovery could bring widespread uses for ’nanocrystals’

Researchers at Purdue University have made a surprising discovery that could open up numerous applications for metal “nanocrystals,” or tiny crystals that are often harder, stronger and more wear resistant than the same materials in bulk form.

The research engineers have discovered that the coveted nanocrystals are contained in common scrap, the chips that are normally collected and melted down for reuse.

“Imagine, you have all of these bins full of chips, and they get melted down

’Jumping genes’ create ripples in the genome – and perhaps species’ evolution

Laboratory experiments led by Hopkins scientists have revealed that so-called “jumping genes” create dramatic rearrangement in the human genome when they move from chromosome to chromosome. If the finding holds true in living organisms, it may help explain the diversity of life on Earth, the researchers report in the current (Aug. 9) issue of Cell.

“Jumping genes,” or retrotransposons, are sequences of DNA that are easily and naturally copied from one location in the genome and inserted els

Studies define biochemical structure that keeps blood pressure low, bypass grafts open

A sort of biochemical scaffold for a compound that enables blood pressure to be low, heart bypass grafts to remain open and nerves to communicate has been identified by Medical College of Georgia researchers.

Researchers say identifying the framework for how these and other very positive health benefits occur should help them find ways to augment the benefits and identify new treatments for cardiovascular disease, which may result when the support structure falls apart.

Genetics in Clinical Practice: A Revolutionary Approach

A DMS professor is leading the way in using computer technology for medical education with a pioneering virtual clinic to teach “Genetics in Clinical Practice.” Joseph V. Henderson, MD, a professor of community and family medicine who heads Dartmouth Medical School’s Interactive Media Lab (IML), created a “virtual practicum in genetics” using state-of-the-art interactive multimedia and world leaders in genetics research to foster more effective continuing medical education at DMS.

UMass geologist leads team probing Bering Land Bridge

Researchers from Woods Hole, Scripps oceanographic institutes sail on new Coast Guard ice breaker to study climate, ocean changes

A University of Massachusetts Amherst geoscientist is part of a team of researchers sailing the Bering and Chukchi seas this summer, searching for clues about the sea floor history and the land bridge that once existed between what is now Alaska and Russia. The team will also explore how the disappearance of the land bridge may have affected that region&#14

Underground Nuclear Explosions Deteriorate The Ozone Layer

Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky of Central Aerology Observatory are authors of this hypothesis.

Winter and spring are the most common seasons for ozone holes above Yakuti
