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 ..

2019 National Science Day (NSD)

The National Science Day (NSD) is observed every yearon 28th of February to mark the discovery of Raman effect by Physicist C V Raman on 28th February, 1928. For his discovery, Sir CV Raman was awarded the Nobel Prize in Physics in 1930. In honour of this discovery and as a mark of tribute to ..

2018 Nobel Prize in Physics awarded

American scientist Arthur Ashkin, French engineer Gerard Mourou and Canadian professor Donna Strickland have been awarded the Nobel Prize in Physics for their work in the field of laser physics. Dr. Ashkin has been awarded the Prize “for the optical tweezers and their application to biological systems. Dr. Mourou and Dr. Strickland have been awarded ..

Hyperspectral Imaging Satellite

The Indian Space Research Organisation (ISRO) is planning to launch a full-fledged niche Earth observation (EO) satellite — called the Hyperspectral Imaging Satellite (HySIS). The HySIS satellite has critical chip called an “optical imaging detector array’” indigenously developed by ISRO. ‘Hyspex’ imaging will enable distinct identification of objects, materials or processes on Earth by reading the spectrum ..

What is Spectrum Cap?

The spectrum cap is the limit of radiowaves a telecom operator can hold for providing wireless services. Spectrum cap rules prevent an operator from buying additional spectrum in a respective band. The idea is to prevent operators from acquiring a disproportional amount of spectrum compared to its peers thereby preventing market dominance. As per existing ..

2012 Physics Nobel for Haroche and Wineland

Serge Haroche of France and David Wineland of America together won the 2012 Nobel Prize in Physics for inventing methods to observe the bizarre properties of the quantum particles without disturbing them. This thing was previously thought unattainable. What is their invention? Their inventions are the methods by which quantum particles like atom, electron or ..

New Laser developed by the Scientists to assist in Detecting Roadside Bombs

A new laser developed by Researchers at Michigan State University United State Department of Homeland Security funded the research and it was published in the journal Applied Physics Letters The laser has the sensitivity and selectivity to look into large areas and detect improvised explosive devices, which cause 60% of coalition soldiers’ deaths in Afghanistan ..
