Protecting the nation from terrorism, breaches in cyber security and other threats inside its borders is such a massive undertaking it is “not easy to draw red lines” that can chart individual or departmental responsibilities, Secretary of Homeland Security Janet Napolitano said during a campus visit on Oct. 6.

In a talk hosted by the Jackson Institute of Global Affairs, Napolitano used the example of the so-called “Underwear Bomber” — a suspected terrorist who attempted to blow up (using explosives hidden in his underwear) a Northwest Airlines flight between Amsterdam and Detroit on Christmas Day 2009 — to illustrate the partnerships that are required to ensure the nation’s safety. Her talk in the Law School’s Levinson Auditorium highlighted the importance of international partnerships in that mission. (more…)

*Water temperature played key role*

In the results of a new study, scientists explain how they used DNA to identify microbes present in the Gulf of Mexico following the Deepwater Horizon oil spill–and the particular microbes responsible for consuming natural gas immediately after the spill.

Water temperature played a key role in the way bacteria reacted to the spill, the researchers found. (more…)

Cell-penetrating peptides, such as the HIV TAT peptide, are able to enter cells using a number of mechanisms, from direct entry to endocytosis, a process by which cells internalize molecules by engulfing them.

Further, these cell-penetrating peptides, or CPPs, can facilitate the cellular transfer of various molecular cargoes, from small chemical molecules to nano-sized particles and large fragments of DNA. Because of this ability, CPPs hold great potential as in vitro and in vivo delivery vehicles for use in research and for the targeted delivery of therapeutics to individual cells. (more…)

COLUMBIA, Mo. – As more and more people use websites like Craigslist to find roommates and advertise apartment vacancies, the opportunities increase for housing discrimination law violations. Rigel Oliveri, an associate dean for faculty research and development and associate professor of law at the University of Missouri School of Law, found that discriminatory online housing ads are almost always posted by people seeking roommates, and are primarily based on familial status.

In a study published in the Indiana Law Review, Oliveri reviewed 10,000 housing advertisements from 10 major U.S. cities. Despite a huge number of housing ads placed daily on Craigslist in cities across the country, Oliveri found relatively few instances of illegal housing discrimination. Of the 10,000 ads she reviewed, she found that only five percent were potentially problematic or illegal. (more…)
