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 ..

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 ..

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 ..

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 ..

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 ..

ISRO to launch a full-fledged niche Earth observation (EO) satellite “HySIS” to enable distinct identification of objects from space

ISRO will soon launch a full-fledged niche Earth observation (EO) satellite called the Hyperspectral Imaging Satellite (HySIS) by using a critical chip it has developed. The purpose of the HySIS satellite is to enable distinct identification of objects from about ..

Scientists at Harvard create world’s smallest radio out of diamond imperfections

Harvard scientists have created the world’s smallest radio receiver out of diamond imperfections called nitrogen-vacancy (NV) centres. The NV centers are capable of emitting single photons or detect very weak magnetic fields. When the NV centers receive radio waves it will ..

Specific Absorption Rate (SAR)

Specific absorption rate is the measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) in electromagnetic field. The term is not restricted to the absorption of Electromagnetic Feild (EMF) and can be used in terms of ..
