If a screening strategy for cervical cancer were introduced, it might provide a good opportunity to offer women other health checks, but it is unclear which interventions should be packaged together. Jane Kim and colleagues (Harvard University) have developed an analytic framework to identify an optimal package of health services to offer to women attending a clinic once for their lifetime cervical cancer screen.
Their model takes into account monetary limitations and possible shortages in trained personnel to do the health checks, and balances these constraints against the likely health benefits for the women. When they set a realistic budgetary constraint (based on the annual health budget of the poorest countries and a single health check per woman in the two decades following her reproductive years), the optimal health package included cervical cancer screening by testing for human papillomavirus (an accurate but complex test), treatment for depression, and screening or treatment for anemia. When a 50% shortage in general (for example, nurses) and specialized (for example, doctors) personnel time was also included, the health benefits of the package were maximized by using a simpler test for cervical cancer and by treating anemia but not depression; this freed up resources in some regions to screen for breast cancer or cardiovascular disease.
The results suggest that the packaging of multiple health services during a single visit has great potential to maximize health gains, provided the right interventions are chosen. The shortage of personnel, which has been ignored in previous analyses even though it is a major problem in many developing countries, affects which health conditions and specific interventions should be bundled together to provide the greatest impact on public health.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
