Fingering the Ends How to Make New Telomeres
Telomerase-mediated healing of broken chromosomes gives rise to terminal deletions and is repressed in most organisms. In ciliated protozoa, however, chromosome fragmentation and de novo telomere addition are part of the developmental program. Work by in this issue of Cell indicates that in Euplotes crassus, this is mediated through switching between different telomerase reverse transcriptase i...
متن کاملAutomatic Fingering System (afs)
One of the most important aspects in playing the piano is using the appropriate fingers to facilitate movement and transitions. The fingering arrangement depends to a certain extent on the size of the musician’s hand. We have developed an automatic fingering system that, given a sequence of pitches, suggests which fingers should be used. The output can be personalized to agree with the limitati...
متن کاملFluctuations in viscous fingering.
Our experiments on viscous (Saffman-Taylor) fingering in Hele-Shaw channels reveal finger width fluctuations that were not observed in previous experiments, which had lower aspect ratios and higher capillary numbers Ca. These fluctuations intermittently narrow the finger from its expected width. The magnitude of these fluctuations is described by a power law, Ca(-0.64), which holds for all aspe...
متن کاملMolecular phenotypes of atherosclerosis: fingering the perpetrators.
The initiation and progression of atherosclerosis appears driven by a combination of genetic and environmental factors. Access to circulating lipoproteins or to molecules shed into the blood from arterial wall cells permits genetic diversity to be evaluated in relation to disease risk; environmental factors are commonly understood to relate to macro-risk such as diet, smoking, etc. However, a m...
متن کاملOn Ends-to-Ends Encryption
In the past few years secure messaging has become mainstream, with over a billion active users of end-to-end encryption protocols through apps such as WhatsApp, Signal, Facebook Messenger, Google Allo, Wire and many more. While these users’ two-party communications now enjoy very strong security guarantees, it turns out that many of these apps provide, without notifying the users, a weaker prop...
