NASA launches Icon satellite to explore where air meets space

NASA has recently launched its new Ionospheric Connection Explorer (Icon)  satellite  from the Cape Canaveral Air Force Station in Florida to explore the mysterious, dynamic region where air meets space. The refrigerator-size Icon satellite will study the airglow formed from gases in the ionosphere and also measure the charged environment right around the 360-mile-high (580-kilometer-high) ..

University of Wisconsin-Madison scientist develops a new pin-sized sensor that can detect dangerous chemicals

The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the ..

Massachusetts Institute of Technology develops optical imaging system ‘DOLPHIN’ for finding tiny tumours

In USA, the researchers at the Massachusetts Institute of Technology (MIT) have developed an imaging system which could be deployed to find tiny tumours, as small as a couple of hundred cells, deep within the body. They used their imaging system, named “DOLPHIN,” which relies on near-infrared light, to track a 0.1-millimetre fluorescent probe through ..

Goa University discovers pigment in wild edible mushroom that may help fight against cancer

Recently, the mycological laboratory of the Department of Botany in Goa University announced the discovery of a new pigment from local wild mushrooms that may help fight against cancer. The result was confirmed after more than two decades of research experience on local wild mushrooms. The chemical nature of the brown or black color pigment ..

XFEL- X-Ray Free Electron Laser

XFEL is the world’s largest and powerful X-ray laser. It was unveiled in Hamburg, Germany.  At present, 11 countries have participated in the project. The European XFEL is constructed such that the electrons produce X-ray light in synchronisation, resulting in high-intensity X-ray pulses with the properties of laser light and at intensities much brighter than those produced by conventional synchrotron light ..
