Construction of proteins with new mechanical properties through recombination of protein fragments

So that we can move, and so that our heart beats, we need proteins with special mechanical properties, "molecular springs", which give our tissues the necessary strength and take care of elasticity and tensibility.

Gene screen for breast cancer better than pathologist's "eye"

Johns Hopkins scientists have found that a method they developed to screen body fluids for certain kinds of cells and some of their genetic blueprint is twice as accurate at spotting breast cancer cells as a pathologist's view with a microscope.

Imaging pancreatic cancer with a peptide-nanoparticle conjugate targeted to normal pancreas

Most attempts to develop imaging agents that can better distinguish tumors from healthy tissue focus on finding molecules that are more abundant on malignant cells than on normal cells and using those as cellular targets.

Early marker for autism found in the placenta

A team from Yale School of Medicine have found an abnormality in the placenta which could be the first indication of autism and they believe the discovery could lead to a diagnosis of the condition at birth, rather than the standard age of two or older.
