Cambridge team exposes EMV card vulnerabilities

(Phys.org)—At a cryptography gathering in Leuven, Belgium, on Tuesday, Cambridge University researchers made it known that they do not like what they see in chip and pin systems. Banks rely on customer confidence in their word that chip and pin systems are safe, but the researchers tell quite a different story. Part of the problem has to do with the number generators, which the researchers give...

Mars rover Curiosity working 'flawlessly': NASA

For the past week, the rover, which touched down on August 6, has undergone a series of instrument tests, as well as a rebooting of its steering computers, and everything so far appears fine, according to officials with the Jet Propulsion Laboratory in Pasadena, California.

'Mini' stroke can cause major disability, may warrant clot-busters

Patients with transient ischemic attack, TIA or "mini" stroke, are not typically given clot-busting drugs because the condition is considered too mild to treat. However, 15 percent of patients had some disability 90 days after a mini stroke. Some patients with minor stroke may benefit from clot-busting drug treatment.

'Smart growth' strategies curb car use, greenhouse gas emissions, SF State study suggests

Smart growth approaches to urban planning could substantially reduce the number of miles that residents drive in a year according to research published in the BE Journal of Economic Analysis and Policy. The study found that a 10 percent increase in a city's smart growth features -- including housing density, jobs per capita and public transit infrastructure -- leads to a 20 percent decrease in the...

2 studies could lead to new personalized therapies for lung cancer patients

Lung cancer is a leading cause of death worldwide and is associated with very low survival rates. Two new genome-sequencing studies have uncovered novel genes involved in the deadly disease, as well as striking differences in mutations found in patients with and without a history of smoking. The findings, published Sept. 13 by Cell Press in the journal Cell, could pave the way for personalized...

Cell death mystery yields new suspect for cancer drug development

A mysterious form of cell death, coded in proteins and enzymes, led to a discovery by UNC researchers uncovering a prime suspect for new cancer drug development.CIB1 is a protein discovered in the lab of Leslie Parise, Ph.D. , professor and chair of the department of biochemistry at the University of North Carolina at Chapel Hill. The small calcium binding protein is found in all kinds of cells.

Charting the SH2 pool

New research published in BioMed Central's open access journal Cell Communication and Signaling describes a large set of interactions which maps the range of phosphotyrosine-dependent interactions with SH2 domains underlying insulin, insulin-like growth factor-1 and fibroblast growth factor signaling pathways.
