Researchers have found that blocking the production of a single
protein in cells from a blood-borne cancer called multiple myeloma
eliminates the cancer cells in laboratory models.

Wide Waists Boost Mortality Risk
People with excess weight have increased health risks, doctors
have long known. But now a new study suggests that even people
in the normal weight range for their heights have increased risks,
too, if their waists are wide.

Success Quitting Smoking Based Partly on Genetics
Smokers’ genetic make-up influences their chances for successful
quitting. According to a new study, it may also help determine
which treatment is most likely to help them quit.

Molecule
Dissolves Fibers Found in Alzheimer’s Disease Patients
Alzheimer’s disease is marked by clumps of protein fibers called
amyloids that accumulate in the brain. Researchers have recently
identified several small molecules that can break up amyloids
in the laboratory. A new study reveals how these small molecules
do this.

How
Songbirds Learn Their Songs
Like human babies, juvenile zebra finches have their own way
of babbling. A new study has found that these vocal explorations
are driven by different brain circuits than those that control
an adult bird’s song. The insight may shed light on how humans
learn new things as we develop.
