Guns and Suicide: Correlation or Causation?

Are Guns There to Kill or to Save Life?

Gunshots are one of the most common modes of deaths and injuries among young Americans in the post-World War II era [1]. The most effective way to prevent firearm injuries is to remove guns from the home and community [1,2]. High rates of injury and death from firearms in United States (US) are in stark contrast to the cities with no or few cases. This difference is most likely related to firea...

Diafiltration for Desalting or Buffer Exchange

Diafiltration is an ultrafiltration membrane technique for completely removing, replacing, or lowering the concentration of salts or solvents from solutions containing proteins, peptides, nucleic acids, and other biomolecules. The process selectively uses permeable (porous) membrane filters to separate the components of solutions and suspensions based on their molecular size. Smaller molecules ...

Guns, Privacy, and Crime

We investigate the impact of an information shock – the public exposure of the names and addresses of holders of handgun carry permits – on criminals’ propensity to commit crimes. In December 2008, a Memphis, TN newspaper published a searchable online database of names, zip codes, and ages of Tennessee handgun carry permit holders. Once news of the database publication spread, an intense and ac...

Developmental Biology: Pipe's Smoking Guns

The formation of the dorso-ventral body pattern of Drosophila involves the restricted activation of a serine protease cascade in the extracellular space between the egg shell and the embryo. Now, the first molecular links have been identified between ventral gene expression during oogenesis and the activation of the protease cascade in the early embryo.
