A report obtained by The Lancet Oncology details a precipitous decline in US Veteran Affairs (VA) reporting of new cancer cases to California registries beginning in late 2004—from 3000 cases in 2003 to almost none by the end of 2005. Inconsistent and incomplete case reporting by VA Hospitals are also long-standing problems for other US states and could mean that cancer rates appear artificially low across the USA.
The omission of veteran data would introduce “uncorrectable bias” in epidemiological studies, and research from the mid-2000s will not be correct, according to Dennis Deapen of the Los Angeles Cancer Surveillance Program. Furthermore, it will hamper efforts to identify quality-of-care issues for VA patients with cancer.
A draft version of the VA policy directive on cancer reporting was obtained by The Lancet Oncology which revealed that the directive will formalise the prohibitions on sharing veteran cancer data between states and forbid the “re-lease” of veteran data to researchers whose studies have not been approved by the VA. “This could become a serious issue for the validity of epidemiological studies” according to Elizabeth Ward of the American Cancer Society. The VA has since posted the final directive on its website.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
