July 18, 2012 - The discovery of an immune molecule could lead
to new treatments for skin cancer. Boston researchers gave mice
with melanoma a cell called TH 9 and it kept the cancer from
growing. Melanoma is the most dangerous form of skin cancer and
doctors say studies involving TH 9 now need to be done on
people. Also, according to a new study, most kids aren't getting
enough physical education. A University of Georgia professor
looked at schools in all 50 states. He found most schools are
coming up short with PE guidelines. In fact, he says only six
states implemented enough gym time for elementary school
students. He says no states had strong enough regulations at the
high school level. Professor McCullick says the pressure to
raise standardized test scores may be to blame. He says schools
may be cutting PE time so students have more time to hit the
books. Right now, there are no federal guidelines for PE.
