Getting sharp images from dull detectors

Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons---the particle complement of light waves---and sometimes only one photon at a time, using "smart" detectors that can count the number of individual photons in a pulse. Furthermore, to observe quantum effects, it is normally necessary to use a beam of coherent light, light for which knowing the phase or intensity for one part of the beam allows you to know things about distant parts of ...

No single explanation for biodiversity in Madagascar

DURHAM, N.C. –- No single "one-size-fits-all" model can explain how biodiversity hotspots come to be, finds a study of more than 700 species of reptiles and amphibians on the African island of Madagascar. By analyzing the geographic distribution of Madagascar's lizards, snakes, frogs and tortoises, an international team of researchers has found that each group responded differently to environmental fluctuations on the island over time. The results are important because they suggest that climate change and land use in Madagascar will have varying effects on different ...

Interactive history beats interactive chat for website engagement

Small cues that display a user's transaction history may help a website feel almost as interactive as chatting with an online customer service agent, paving the way for more cost-effective websites, according to researchers. "One of the challenges with online interactivity is trying to imbue the site with a sense of contingency -- the back-and-forth feel of a real conversation," said S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory. "What we found is that providing some information about a user's interaction ...

Antiretroviral therapy benefits HIV-infected stimulant users, UCSF study shows

New clinical research from UC San Francisco shows that 341 HIV-infected men who reported using stimulants such as methamphetamine or cocaine derived life-saving benefits from being on antiretroviral therapy that were comparable to those of HIV-infected men who do not use stimulants. That said, those who reported using stimulants at more than half of at least two study visits did have modestly increased chances of progressing to AIDS or dying after starting antiretroviral therapy compared to non-users. The data was collected between 1996 and 2012. "Patients with HIV ...

Rare 'baby rattle' molecules reveal new quantum properties of H2O and H2

The experiments were carried out on endofullerenes, molecules of C60 into which smaller molecules of Hydrogen (H2) had been inserted. The results, published in Physical Review Letters, represent the first known example of a quantum selection rule found in a molecule. Similar techniques were also used by the same team to uncover an exciting new symmetry-breaking interaction of water molecules with C60 cages, published last month in Physical Chemistry Chemical Physics. The use of fullerenes such as C60 to trap smaller molecules, using cutting-edge molecular surgery techniques, ...

Old textbook knowledge reconfirmed: Decay rates of radioactive substances are constant

This news release is available in German. The distance between the Earth and the Sun has no influence on the decay rate of radioactive chlorine. You could ask: "And why should it anyway?", because it is well known that the decay of radionuclides is as reliable as a Swiss clock. Recently, US-American scientists, however, attracted attention when they postulated that the decay rate depends on the flow of solar neutrinos and, thus, also on the distance from the Earth to the Sun. Their assumption was based, among other things, on older measurement data of the Physikalisch-Technische ...

Mineralization of sand particles boosts microbial water filtration

WASHINGTON, DC – OCTOBER 10, 2014 - Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Microbiology. These findings resoundingly refute, for the first time, the conventional wisdom that the mineral deposits interfere with microbial colonization of the sand particles. "We find an overwhelmingly positive effect of mineral deposits on microbial activity and density," says corresponding author Barth ...

Dangerous blood clots: A serious global problem

A study on the global burden of venous thromboembolism—when a dangerous clot forms in a blood vessel—found that annual incidences range from 0.75 to 2.69 per 1,000 individuals in the population. The incidence increased to between 2 and 7 per 1,000 among those 70 years of age or more. "Venous thromboembolism in hospitalized patients was responsible for more years lost due to ill-health than hospital-acquired pneumonia, catheter-related blood stream infections, and side effects from drugs," said Dr. Gary Raskob, co-author of the Journal of Thrombosis & Haemostasis ...

An unexpected bonus

The so-called Signal Transducers and Activators of Transcription, or STATs, are key components of many different signalling pathways. Not surprisingly, then, when something goes wrong with their regulation the consequences can be severe and many types of cancer are known to be associated with increased activities of one or more STAT protein. STAT3 is a frequent culprit and is often found to be activated in tumour cells. Considerable efforts are going into developing inhibitors of STAT3 for use in cancer therapy but it is unclear whether these will turn out to be suitable ...
