With artificial cornea, he restores gift of sight



Dr. Claes Dohlman, considered the "founder of modern corneal science," recently received the Laureate Recognition Award from the American Academy of Ophthalmology for his contributions in restoring sight worldwide. And he won the Global Leadership Award from the Massachusetts Eye and Ear Infirmary, where he was chairman of the ophthalmology department. He was also chairman of the department at Harvard ...

• Survival of the Teliosporogenous Mycelia of Neovossia indica in Infected Wheat Grains
In this investigation, survival of the teliosporogenous mycelia in 6, 7, 8 and 9 months old bunted kernels which had been infected artificially in the laboratory was examined. The sorus of each treatment was crashed in sterile distilled water and the suspension was placed on the surface of sterile distilled water in a completely randomized design with 5 replicates per treatment. Ten to 15 days later, floccose erected mycelia showing characteristics of the teliosporogenous mycelia appeared in the plates containing suspension that had been prepared from 6-8 months old infected kernels. Fifteen days after inoculation, colony numbers of teliosporogenous mycelia per plate were counted. Two- three weeks after transferring the mycelia to fresh YPDA, teliospores formed on this medium. After 4 weeks, mean teliospore formation on YPDA at 20°C and under laboratory conditions were 591.5 and 832 per plate, respectively. Also the teliosporogenous mycelial growth rate on YPDA at 20°C and room temperature were 2.31 and 1.85 mm day-1, respectively. Fungus teliosporogenesis was studied in vitro and in situ by light, fluorescent and scanning electron microscope. During the teliosporogenesis, teliospore initials were formed in apical position in a lateral right-angled outgrowth of the teliosporogenous hyphae. The dikaryotic plasma was concentrated in the apical portion of the hypha. Fusion of nuclei occurred during the early enlargement of teliospore initial. The swelling, pyriform to spherical protoplast of the teliospore initial was delimited from the empty part of teliosporogenous hypha by a sheath, which was hyaline as observed by LM. The empty part of the hypha may form appendages. Underneath the sheath, the exosporium with ornamented surface and the smooth endosporium was deposited as seen in the mature teliospores. This is the first report of survival of the teliosporogenous mycelia in the Karnal bunt infected kernels after several months of storage. This may be of great importance in pathogen survival and disease epidemiology.

• Diversity among parasitic wasps is even greater than suspected
A tiny wasp that lays its eggs under the skin of unwitting caterpillars belongs to one of the most diverse groups of insects on Earth. Now researchers report that its diversity is even higher than previously thought.

• Physics of the Impossible by Michio Kaku

Physics of the Impossible A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel
Written by Michio Kaku

Trade Paperback, 352 pages | Anchor | Science - Physics | $15.95 | April 14, 2009 | 978-0-307-27882-1 (0-307-27882-4)

A fascinating exploration of the science of the impossible—from death rays and force fields to invisibility cloaks—revealing to what extent such technologies might be achievable decades or millennia into the future.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:
· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”
· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars
· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology
· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one
Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.
