Cornell University is offering a hands-on, distance education course, "The How, When and Why of Grafting for Gardeners," which will teach universal criteria for grafting and techniques such as chip budding, T-budding and top-wedge grafting.
To inspire and inform youth workers and others interested in cultivating environments that promote positive youth development and behavior, two experts from Cornell University have published a book that summarizes current theory, research and practice in the field.
'Garden of Lights,' a design by a team that included Cornell University undergraduate Sean Corriel, was one of three finalists in the competition for a memorial at the site of the former World Trade Center.
For men who suffer from enlargement of the prostate, combining two classes of drugs reduces the risk of significant worsening of symptoms and other BPH complications by 66 percent, according to a multi-center study authored by a physician-scientist at NewYork-Presbyterian Hospital/Columbia University Medical Center.
New York, NY -- Two physician-scientists from New York-Presbyterian Hospital and Weill Cornell Medical College were co-authors of a new study which demonstrates that earlier laser treatment for certain premature infants resulted in an overall better vision outcome. Results of the multi-center clinical trial, sponsored by the national eye institute (nei), a part of the national institutes of health (NIH), and published in the December issue of the Archives of Ophthalmology, give physicians new, improved treatment options for retinopathy of prematurity (ROP), a blinding disease that affects premature, low-birth-weight infants and is a leading cause of vision loss in children.

Leave it to Bill Nye "the Science Guy" to turn a traditional piece of calibration equipment into a really cool, state-of-the-art scientific instrument. As he was looking over the designs for instruments to be carried aboard NASA's 2001 Mars Surveyor Lander.
The National Science Foundation (NSF) has designated a 13-member national consortium as the National Nanotechnology Infrastructure Network (NNIN), creating the world's largest and most accessible nanoscale laboratory. The consortium will enable university students and researchers, as well as scientists from corporate and government laboratories, to have open access to resources they need for studying molecular and higher length-scale materials and processes and applying them in a variety of structures, devices and systems. Named to lead NNIN is Sandip Tiwari, director of the NSF-funded Cornell Nanoscale Facility (CNF), a national user facility on the Cornell campus. NSF funding to the new network is expected to be $70-million or higher for five years, beginning in January 2004, with the possibility of a five-year renewal. (December 22, 2003)
Steven Squyres, the principal investigator for the science instruments aboard the Spirit and Opportunity Mars rovers, juggles his commitments to the four space missions he is actively involved in, as well as to his teaching and advising duties.
PASADENA, Calif. -- The Cornell University-developed, mast-mounted panoramic camera, called the Pancam, on board the rovers Spirit and Opportunity will provide the clearest, most-detailed Martian landscapes ever seen. The image resolution -- equivalent to 20/20 vision for a person standing on the Martian surface -- will be three times higher than that recorded by the cameras on the Mars Pathfinder mission in 1997 or the Viking Landers in the mid-1970s.
PASADENA, Calif. -- Facelifts can sag. Botox is temporary. But modern science has a new way to return youth to weathered faces: the rock abrasion tool (RAT). If your dermatologist hasn't heard of it, ask your local Mars scientist. Billions of years of exposure to the sun, atmosphere and extremely fine Martian dust has given Mars rocks a weathered "rind," or exterior layer. The RAT, part of the science-instrument package carried by the two Mars rovers, Spirit and Opportunity, uses a diamond-tipped robotic grinding tool to scrape away this weathered exterior, revealing a fresh surface.

PASADENA, Calif. -- After the twin Mars Exploration Rovers bounce onto the red planet and begin touring the Martian terrain in January, onboard spectrometers and cameras will gather data and images --- and the rovers' wheels will dig holes. Working together, a Cornell University planetary geologist and a civil engineer have found a way to use the wheels to study the Martian soil by digging the dirt with a spinning wheel. "It's nice to roll over geology, but every once in a while you have to pull out a shovel, dig a hole and find out what is really underneath your feet," says Robert Sullivan, senior research associate in space sciences and a planetary geology member of the Mars mission's science team. He devised the plan with Harry Stewart, Cornell associate professor of civil engineering, and engineers at the Jet Propulsion Laboratory (JPL) in Pasadena. (December 19, 2003)
