Pfister said Donoghue is well-known in the field for his work with philogenetic trees, the analysis of the relationships between different vascular plants in a broader evolutionary context. He said Donoghue is also working with molecular techniques important in molecular philogeny, which studies how molecular characteristics and components of different groups explain group evolution...
...science is beginning to fulfill its promise. Researchers who look at many diseases as a failure of stickiness are designing both antisticky drugs and Super Glue-like drugs to treat a range of disorders, including heart disease, transplant rejection, stroke, arthritis, shock and cancer. Michael Gimbrone Jr., head of vascular research at Harvard Medical School, predicts "a whole new generation of therapeutic interventions." Several drugs are now being tried on humans, and early next year the first of them -- a gel that spurs wound healing -- will enter the final U.S. government approval process...
...with a hardier elm. The tree is called the American Liberty Elm (after a famed Massachusetts tree under which George Washington purportedly took command of the Continental Army in 1775). The American Liberty has a smaller cell structure that prevents Dutch elm disease from spreading through the tree's vascular system. So far, Elm Research has distributed 75,000 of the new trees for prices ranging from $ $2 to $5 each, a good start on its target of 1 million by the turn of the century. Says John Hansel, the institute's director and founder: "We will start seeing some...
Harvard courses taught through the arboretum include introductory biology classes, an extension school course on vascular plants and a course taught by Koller on botany...
...threaded into a blocked passage and inflated. Atherosclerotic plaque is crushed against the artery walls, widening the blood pathway. Yet another delicate operation entails tying off penile veins that fail to close during sexual arousal, thus allowing blood to leak away from the penis and inhibiting an erection. Vascular operations carry steep price tags...
