The possibility of using antibodies to treat variant Creutzfeldt-Jakob
disease (vCJD) receives a boost this week, with the first promising results from
an animal trial.
Yeast evolution reversed
Nature Science Update
March 6, 2003
http://www.nature.com/nsu/030303/030303-5.html
Scientists have turned two species back into one by shuffling parts of
chromosomes. The achievement demonstrates that genome rearrangements can drive
species apart.
Gut up and go
The Scientist

Scientists show that sequence differences among extant H. pylori
populations correlate with large-scale human migrations — both ancient and
recent — and may help resolve questions about human movements through time.
Sleeping sickness foe unmasked
The Scientist
March 6, 2003
http://www.biomedcentral.com/news/20030306/03/
Researchers have discovered how trypanosomes evade immune responses and
become infective.
Post-genome project launches
The Scientist
March 5, 2003
http://www.biomedcentral.com/news/20030305/02/
The National Human Genome Research Institute (NHGRI) will formally launch a
consortium project to develop methods for identifying and locating functional
elements of the human genome.
Microbes rule
The Scientist

Microbial genomic data are paving the way for new and improved vaccines,
better-tasting and safer fermented foods and beverages, stronger biodefense, and
a cleaner environment.
Exploring the microbial world
The Scientist

Researchers want to know how microbes interact, survive, and thrive—and
how they can benefit humankind.
Superbug strain hits healthy
New Scientist

MRSA bacterium has long been a serious problem in hospitals and nursing homes
but it now appears that a new strain is emerging that can even infect healthy
people.
Diamond film may
enable critical new sensors for bioterror
University of Wisconsin-Madison

The new technology is centered on a newfound ability to make highly stable,
DNA-modified diamond films.
Bad bacteria key
to drug delivery
Wired News

A team has modified Escherichia coli so that one of its flagella is
tethered to the platform of the nanodispenser.
Researchers
identify protein that helps HIV penetrate cells
University of Texas Medical Branch
March 6, 2003
http://www.newswise.com/articles/2003/3/HIV.TMB.html
Scientists have identified a crucial link in the process that HIV, the virus
that causes AIDS, uses to get inside one kind of human white blood cells.
Do vaccines
cause asthma, allergies or other chronic diseases?
Children’s Hospital of Philadelphia
March 5, 2003
http://www.eurekalert.org/pub_releases/2003-03/chop-dvc030303.php
Large scientific studies do not support claims that vaccines may cause
chronic diseases such as asthma, multiple sclerosis, chronic arthritis, and
diabetes, according to a report.
How dendritic
cells grow up to take on foreign invaders
Ludwig Institute for Cancer Research
March 3, 2003

A study explains how cells crucial to the body's defense system can
stimulate an immune response, raising new possibilities for their use in cancer
vaccines.
Scientists
isolate microorganisms that break down a toxic pesticide
University of California, Riverside
March 4, 2003
http://www.newsroom.ucr.edu/cgi-bin/display.cgi?id=535
Scientists report that they have isolated microorganisms capable of
degrading endosulfan, a chlorinated insecticide widely used all over the world.
Anti-HIV protein
from blue-green algae also inhibits Ebola infection
NIH/National Cancer Institute
