DNA Shape Is Constrained By Evolution: Structural Approach To Exploring DNA
A team led by researchers from Boston University and the National Institutes of Health has developed a new method for uncovering functional areas of the human genome by studying DNA’s three-dimensional structure — a topographical approach that extends the more familiar analysis of the sequence of the four-letter alphabet of the DNA bases.
Unlike the well-understood [...]
Is The Hippopotamus The Closest Living Relative To The Whale?
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy.
Jessica Theodor, an associate professor in the Department of Biological Sciences at the University of Calgary, and her colleague [...]
New Genre Of Sugar-coated ‘Quantum Dots’ For Drug Delivery
Scientists in Switzerland are reporting an advance that could help tap the much-heralded potential of “quantum dots”— nanocrystals that glow when exposed to ultraviolet light — in the treatment of cancer and other diseases.
They are publishing the first study showing that giving quantum dots an icing-like cap of certain sugars makes these nanoparticles accumulate in [...]
Bacteria-killing Enzyme Cures Mice With Fatal Pneumonia
Before the advent of antibiotics, pneumonia claimed so many lives — and was so feared — that it was called the “captain of the ship of death.” Now, at a time when the new antibiotics have proved futile against resistant strains of bacteria, researchers at Rockefeller University are using a different tactic to keep this [...]
