Laced Rice
The people of Bangladesh and neighboring countries are battling the
problem of arsenic in their groundwater, a deadly offshoot of the massive
tube-well drinking water program undertaken in the 1970s in an effort
to provide bacteria-free water to millions of people. This same water
is used to irrigate rice paddies, where the dietary staple is grown.
Professor Om
Parkash, Plant, Soil, and
Insect Sciences, leads a research
team that uses genetic engineering to produce rice plants that block
the uptake of arsenic, a known carcinogen. According to Parkash, arsenic
builds up in all parts of the plant, including the grains used for
human food and the straw used as animal fodder, creating health problems
in hundreds of thousands of people.
Mighty Math Machine
It’s bigger than a breadbox (but
smaller than most refrigerators), has 608 linked processors, and can
perform an estimated five billion math operations every second (compared
to the average human, who needs about three seconds to perform one
large multiplication operation). Cyclops, so named for its single screen,
is a new supercomputer purchased for $120,000 by the College
of Engineering.
It can solve “horrendously complex equation systems,” says Blair
Perot,
director of the Theoretical
and Computational Fluid Dynamics Laboratory.
Under a grant from the U.S. Navy, mechanical engineering doctoral student
Michael
B. Martell is already using Cyclops, to study the difference
in drag between rough and smooth surfaces on a ship’s hull. Martell
says the computer has calculated a counterintuitive finding: that there
is a significant reduction in drag using a material with tiny posts
or ridges on its surface.
Greener Golf
Maintaining lush fairways requires intensive application of pesticides,
herbicides, and fungicides. Are chemicals poisoning golfers, and
can we reduce their environmental impact? Toxicologist John
Clark,
Veterinary and Animal Sciences,
wanted answers. In one study he conducted, volunteers played 76 rounds
of golf. Some were dressed in cotton clothing and veils to measure
transferred pesticide residues; other were tested directly for absorbed
pesticides. The players walked 6,500 yards; each hit a ball 85 times,
and took 85 practice swings on the test plot at UMass
Amherst’s Turfgrass Research Center in
South Deerfield, following applications of pesticides. The good
news: even under a worst case scenario, exposure was 19 to 68 times
below current EPA values designed to protect human health. In other
studies, Clark, who also works with Guy
Lanza, Microbiology,
identified plants that can be employed as living filters at the edge
of golf courses to remove harmful pesticides from the environment.
Blue
flag iris was the clear winner; after three months of growth,
it reduced in the soil levels of a commonly used insecticide by 76
percent and levels of a widely-used fungicide by 94 percent.
Work Out Then Wait
Swilling a high
carb sports drink or munching an energy bar after exercising
could be sabotaging some of the health benefits, says Barry
Braun ’91G, associate professor of Kinesiology and director of the Energy
Metabolism Laboratory. Grad student researchers recently published
three studies on the topic. Overall, they determined that the metabolic
health benefits of exercise, such as lower risk for diabetes and
heart disease, can be reduced when spent calories are quickly replaced
with high carb foods. While it might not apply to competitive athletes,
people exercising to improve their health might be wiser to stick
with water and lower carb foods for one to three hours after working
out.
