Mathematical Patterns That Eventually Fail
Sometimes patterns can lead you astray. For example, it’s known that $latex \displaystyle{ \mathrm{li}(x) = \int_0^x \frac{dt}{\ln t} }$ is a good approximation to $latex \pi(x),$ the number …

Duke Team Finds Missing Immune Cells That Could Fight Lethal Brain Tumors
DURHAM, N.C. -- Glioblastoma brain tumors can have an unusual effect on the body’s immune system, often causing a dramatic drop in the number of circulating T-cells that help drive the body’s defenses. Where the T-cells go has been unclear, even as immunotherapies are increasingly employed to stimulate the body’s…
