Two studies by researchers at UT Southwestern Medical Center could lead to new treatments for lupus and other autoimmune diseases and strengthen current therapies for viral, bacterial, and parasitic infections.

Quantum cryptography put to work for electric grid security

Recently a Los Alamos National Laboratory quantum cryptography (QC) team successfully completed the first-ever demonstration of securing control data for electric grids using quantum cryptography.

The demonstration was performed in the electric grid test bed that is part of the Trustworthy Cyber Infrastructure for the Power Grid (TCIPG) project at the University of Illinois Urbana-Champaign (UIUC) that was set up under the Department of Energy’s Cyber Security for Energy Delivery Systems program in the Office of Electricity Delivery and Energy Reliability.

Combo of Avastin, Second Drug Shows Promise Fighting Brain Cancer, Mayo Clinic Finds

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens. They have also discovered that pairing Avastin with another cancer drug, dasatinib, can stop that lethal spread. Dasatinib is approved for use in several blood cancers.

Researchers uncover new findings on genetic risks of chronic inflammatory disorder Behçet's disease

Posted: 15 Feb 2013 07:27 AM PST

Researchers don’t know the exact cause of Behçet's disease, a chronic condition that leads to oral and genital sores and serious complications such as blindness, but new research brings better understanding to what makes some people more susceptible to being affected. Study identifies regions of genes linked to Behçet’s, a poorly understood condition that causes painful and serious symptoms, including ulcers and brain inflammation.
