1) Lifting fingerprints without touching the surface; 2) Detecting Alzheimer's early by looking in the eye; 3) Capturing natural lighting in computer-animated movies.
How many people do airplanes wake up nightly? How different must two drug names sound to prevent doctors and patients from confusing them? What sound can bacteria generate to help workers monitor waste-management equipment? These questions and others will be answered at the annual meeting of the Acoustical Society of America.
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. By "nulling" out the light of the parent star by exploiting the light's wave nature, remaining reflected light from the planet can be observed in space-based detectors.
Which US groups have the best and worst hearing? How have researchers improved cell-phone sound quality without changing the existing infrastructure? These questions and more will be answered in a web pressroom and a press luncheon for the Acoustical Society of America meeting in Providence, RI.
Non-Hispanic black adults in the US have on average the best hearing in the nation, a new study shows, with women hearing better than men in general. Overall, the nation's hearing health remains about the same as it was 35 years ago, despite massive changes in society and technology.
Health physicists are establishing safe procedures for a promising experimental brain-cancer therapy which uses radioactive scorpion venom. The venom of the yellow Israeli scorpion preferentially attaches to the cells of a type of essentially incurable brain cancers known as gliomas. This preference can be exploited to killing brain cancer cells non-invasively. Information about the study will be presented this week at the Health Physics Society meeting in Providence, RI.
To help computers provide faster "second opinions" on mammogram images showing suspicious-looking breast masses, medical physicists at Duke University are employing a Google-like approach that retrieves useful information from an existing mammogram database within three seconds.
Super-intense radiation delivered by a robotic arm eradicated lung tumors in some human patients just 3-4 months after treatment, medical physicist Cihat Ozhasoglu, Ph.D. of the University of Pittsburgh Medical Center will report in early August at the 48th Annual Meeting of the American Association of Physicists in Medicine in Orlando.
By studying how a single electron behaves inside an electronic bottle, Harvard physicists were able to calculate (six times more precisely than the previous measurements) a new value for a number called the fine structure constant, which specifies the strength of the electromagnetic force, which holds electrons inside atoms.
Scientists have unveiled a new technology that could lead to video displays that faithfully reproduce a fuller range of colors than current models, giving a life-like viewing experience. The invention, based on fine-tuning light using microscopic artificial muscles, could turn into consumer products in eight years, the scientists say.
