This week, thousands of graduating medical students around the country will find out where they’ll head next, to start their residency training. But a new study gives the first objective evidence of the heavy toll that the first year of residency can take on their sleep, physical activity and mood.
In supersonic engines, achieving the right flow speed, producing the right ratio of evaporated fuel and causing ignition at the right time is complex. Vortices are affected by the shock wave, and this changes the way the fuel combusts and multiplies the number of possibilities of how particles can behave. To deepen our understanding, researchers use numerical modeling to calculate the huge variety of possible outcomes. They discuss their work in Physics of Fluids.
A new study shows that higher doses of radiation do not improve survival for many patients with prostate cancer, compared with the standard radiation treatment. The analysis, which included 104 radiation therapy oncology groups across North America, was led by researchers at Washington University School of Medicine in St. Louis.
•The ability of the “cold sore” herpes simplex virus to establish quiet infections and reawaken periodically has long mystified scientists. •A new study in mice reveals that a key host protein acts as a critical regulator of the virus’s sleep-wake cycle. •Disabling two viral binding sites for the protein weakened the virus’s ability to come out of hiding.
When noble metals are treated with an aliphatic thiol, a uniform monolayer self-assembles on the surface; this phenomenon is interesting because the conducting molecules produce unique quantum properties that could be useful in electronics. Attempts to measure the current across this thin skim have yielded varied results, but researchers in France developed a stable mechanical setup to measure conductance across individual molecules with greater success. The results are in this week’s Journal of Applied Physics.

Chemical compounds carry distinctive absorption “fingerprints,” within the mid-infrared spectral region; this offers an opportunity to measure and study chemicals at extremely sensitive levels, but researchers currently lack the tools required. In a breakthrough, NIST researchers developed an on-silicon-chip laser source with outputs that consist of precisely defined and equally spaced optical lines within the mid-infrared spectral region. They report their findings in APL Photonics.
UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called “nanospears” for the targeted delivery of biomolecules such as genes straight to patient cells.

Spin caloritronics explores how heat currents transport electron spin, and researchers are particularly interested in how waste heat could be used to power next-generation spintronic devices. The thermally driven transport application of spin caloritronics is based on the Seebeck effect; researchers in China have theoretically exposed the fundamental aspects of this thermal transport along double-stranded DNA molecules. They reported their findings in the Journal of Applied Physics.
A Ludwig Cancer Research study shows that ovarian cancer, which has proved resistant to currently available immunotherapies, could be susceptible to personalized immunotherapy. Led by Ludwig Lausanne investigator Alexandre Harari and George Coukos, director of the Ludwig Institute for Cancer Research, Lausanne, the study shows that ovarian tumors harbor highly reactive killer T cells—which kill infected and cancerous cells—and demonstrates how they can be identified and selectively grown for use in personalized, cell-based immunotherapies.

Individuals with lower-pitched voices are more likely to win elected office because they are believed to be superior leaders. But is voice pitch a reliable signal of leadership quality? And is the bias in favor of selecting leaders with lower voices good or bad for democracy? A novel study is the first to address these questions.
Bioreactors, which are woodchip-filled ditches and trenches, are often used near crop fields to filter the water running off of them. The woodchips enhance a natural process called denitrification that prevents too much nitrogen from getting into other bodies of water like rivers and streams.
