Trial Shows Promise for Curing Puppies

June 2, 2014 12:00 pm | by Associated Press, Dave Kolpack | News | Comments

A company that discovered an antibody technology while trying to cure flocks of dying geese is using its research for a more warm and fuzzy purpose: saving puppies. Early tests performed on about 50 puppies in seven states have resulted in a 90 percent cure rate for canine parvovirus, which spreads through animal waste and direct contact between dogs.

Nanotubes Used to Track Movement Inside Cells

June 2, 2014 7:00 am | by Rice Univ. | Videos | Comments

Chemical engineers and biophysicists have successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, they found that cells stir their interiors using the same motor proteins that serve in muscle contraction.

Wormlike Motion Lets Gels Wiggle Through Water

June 2, 2014 7:00 am | by Univ. of Cincinnati | News | Comments

Next time you spot an earthworm sliding through fresh dirt, take a closer look. What you’re seeing is an organic movement called peristaltic locomotion that has been meticulously refined by nature. Now, an undergrad has used a worm’s contracting and expanding motion to provide a way for gels to swim in water.

Drug Protects Cancer Patients' Fertility

June 2, 2014 7:00 am | by Associated Press, Marilynn Marchione | News | Comments

Doctors may have found a way to help young breast cancer patients avoid infertility caused by chemotherapy. Being given a drug to shut down the ovaries temporarily seems to boost the odds they will work after treatment ends, and it might even improve survival.
