Chemical derived from vitamin-E shows early promise as cancer drug
...one of 10 alpha-TEA aerosol-treated mice developed visible lung tumor lesions in comparison to five of 10 untreated control mice. None of the treated animals showed any type of general symptoms of toxicity to alpha-TEA, which Kline chose for further study in 1997 from 50 candidates. Because cancer may...Binocular rivalry: Fulfilling visual expectations

Unlike the wristwatch, however, there is no visible readout or display showing an individual's body time, a lack which has stood as one of the major barriers to realizing the promise of chronotherapy, which seeks to deliver drug treatments at optimal body times.

...eutrons could provide better image resolution than visible light because they have shorter wavelengths---as short as 1 nanometer (nm) compared to 400-700 nm. In this demonstration at NIST's Center for Neutron Research, the microscope produced a resolution of only 0.5 millimeters and a magnification of about ...Whale carcass yields bone-devouring worms
