Rapid response to natural disaster: ESA Sentinel-1 will launch new capability

Next week, on 3 April, a new era will begin in remote-sensing-aided disaster response. The European Space Agency (ESA) has announced that the Sentinel-1A radar satellite will be launched from the European spaceport in French Guiana.
Sentinel-1 is designed for responding rapidly to aid emergencies and disasters such as flooding and earthquakes. The first satellite carries an advanced radar sensor to image Earth’s surface through cloud and rain and regardless of time of day.
Each Sentinel mission is based on a constellation of two satellites to provide robust datasets for Copernicus Services, the new name for the Global Monitoring for Environment and Security program, previously known as GMES.
The initiative is headed by the European Commission in partnership with the European Space Agency (ESA). It will provide accurate, timely and easily accessible information to improve the management of the environment, understand and mitigate the effects of climate change and ensure civil securit…

Colonoscopy: photonics at work, saving lives

Having a colonoscopy? If you're 50 or older, is there really a question?
No question at all -- if you have the means to go in for a colonoscopy, do so. The optics-and-photonics-enabled technology could save your life.
So say the results of recent research into the effectiveness of the endoscopic inspection of the colon as a means of detecting and removing cancerous or potentially dangerous growths, reports optics.org on an analysis of clinic data from the American Cancer Society (ACS).
In the USA, say ACS authors in the journal CA, colorectal cancer is the third most common cancer and the third leading cause of death from cancer.
As with all cancers, early detection is key.
The colonoscopy -- employing an external light source, fiber optics to carry light and data, a lens system, and imaging software and hardware -- offers the advantage of both detecting and potentially preventing cancer, via the removal of polyps.
The ACS paper is one of several recent reports illustrating the …
