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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
