Study provides new guidelines for assessing severity of head and neck cancers
Cedars-Sinai investigators have developed a new, more accurate set of guidelines for assessing the severity of head and neck cancers and predicting patient survival. The new guidelines, outlined in a study recently published in the Journal of Clinical Oncology, center around counting the number of malignant lymph nodes found in each patient.

Chasing dark matter with the oldest stars in the Milky Way
Just how quickly is the dark matter near Earth zipping around? The speed of dark matter has far-reaching consequences for modern astrophysical research, but this fundamental property has eluded researchers for years. In a paper published Jan. 22 in the journal Physical Review Letters, Princeton researchers provided the first clue: The solution to this mystery, it turns out, lies among some of the oldest stars in the galaxy.

Tracking wastewater's path to wells, groundwater
We often 'flush it and forget it' when it comes to waste from toilets and sinks. However, it's important to be able to track this wastewater to ensure it doesn't end up in unwanted places. Tracing where this water ends up is hard to measure: What's something found in all wastewater that will allow us to account for all of it? The answer, of all things, is artificial sweeteners.

Physicists have learned to change the wavelength of Tamm plasmons
Scientists from Siberian Federal University (SFU) and the L. V. Kirensky Institute of Physics (SB RAS) conducted theoretical studies of hybrid Tamm plasmons. Using numerical calculations, they were able to predict the structure in which it is possible to control the wavelength of these quasiparticles by means of an external electric field or heating. The study is presented in the Journal of the Optical Society of America B.

Mitigation techniques fall short of preventing electrocution of golden eagles on power poles
Despite efforts to retrofit power poles and to build new poles to avian-friendly standards, electrocution remains a substantial cause of death for the golden eagle. The global conservation problem results in an estimated 504 eagles electrocuted annually in North America alone. A new Journal of Wildlife Management article examines the risk factors and mitigation techniques from literature published from 1940-2016 and provides new strategies by region to target high-risk poles that could substantially reduce the mortalities.
