Staph infections resistant to antibiotics, previously only associated with hospitalization or prior contact with the healthcare system, are now widespread in the community and coming home. A new study from Emory University School of Medicine and Grady Memorial Hospital, featured in the March 7, 2006 Annals of Internal Medicine, reports on a dramatic rise in antibiotic resistant community-acquired methicillin-resistant Staphylococcus aureus (MRSA), making it the primary cause of skin and soft tissue infections. An editorial accompanying the article notes, "the number of populations at risk for community-acquired MRSA infections is steadily expanding", making it a "remarkable epidemic."
The bacterium Staphyloccus aureus (staph) normally resides on skin and in noses, and typically infects tissues through cuts or rashes. Those infections can remain minor, or lead to illnesses ranging from boils or abscesses to necrotizing skin infections, pneumonia and sometimes blood stream infections. The Centers for Disease Control and Prevention (CDC) reports that staph is one of the leading causes of skin infections in the United States.
Previously, scientists have categorized staph into two main types: antibiotic resistant (MRSA), and methicillin-susceptible Staphyloccus aureus (MSSA), which can be treated by antibiotics in the penicillin or related groups (i.e, beta-lactam antibiotics). Previously, MRSA infections were usually restricted to hospital or healthcare-associated infections. This is clearly no longer the case.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
