Embarking on science's
The moment came early on, in the first year of what is now
an annual lecture series. Benjamin Carson, the
world-renowned neurosurgeon, had just finished telling a
packed auditorium the story behind his medical achievements.
As David Fitter, then a sophomore, left the auditorium, he
overheard someone say, "Wow. Now I remember why I wanted to
be a doctor."
Inspiration. That has been the main goal
and result of the first two years of the Voyage and
Discovery lecture series, which this month kicks off its
third season at Homewood with five more noted Hopkins
researchers and physicians agreeing to share the story
behind the story.
New twist in genes-to-proteins
DNA's protein-building instructions can combine in an
unexpected way, increasing the number of possible proteins
that can be generated from a given number of genes,
according to a report in the Feb. 22 issue of
The new finding may have important
implications for scientists puzzled by the mid-February
announcement that an initial survey of the human genetic
code had found an unexpectedly small number of genes.
Traditional scientific thinking supposes
that instructions for building a protein are encoded on one
strand of the double-stranded DNA molecule. Researchers at
the Krieger School of Arts and Sciences identified a fruit
fly protein whose instructions follow one strand of the DNA
molecule but also include a segment that follows the
opposite strand, which "reads" in the opposite direction.
