Put that hunchback over here
Cristae in crisis ristae, the complex involutions of the mitochondrial inner membrane, vastly increase the surface area across which ATP synthase can generate a proton gradient. Now, new findings from Jean Velours (Université Victor Ségalen, Bordeaux, France) and colleagues suggest that ATP synthase may be important in forming cristae in the first place. Velours' theory is that oligomerization ...
متن کاملHere Today, Here Tomorrow? Urinary Concentrations of Parabens over Time
For many years, the “superbug” methicillin-resistant Staphylococcus aureus (MRSA) was confined to hospital patients, but since the 1990s it has been infecting otherwise healthy people in settings such as schools and locker rooms. Researchers now report the discovery of MRSA in U.S. wastewater treatment plants (WWTPs), identifying another possible environmental reservoir for the bacteria [EHP 12...
متن کاملPsst, Over Here: Communicating Without Fixed Infrastructure
This paper discusses a way to communicate without relying on fixed infrastructure at some central hub. This can be useful for bootstrapping loosely connected peer-topeer systems, as well as for circumventing egregious policy-based blocking (e.g., for censorship purposes). Our techniques leverage the caching and aging properties of DNS records to create a covert channel of sorts that can be used...
متن کاملHere, there, and everywhere
T he main hurdle for genome sequencing projects these days is no longer the effort and cost of generating sequence data—which has become exponentially cheaper—but the capacity to analyse huge amounts of data and make sense of it. This endeavour is made harder by another problem that has begun to emerge over the past years: DNA contamination. Contamination impacts both sequence data generation, ...
