Higgs Boson and Origin of Universe -Science Day Celebration


Report on Seminar on “Higgs Boson and Origin of Universe”
(Science Day Celebration)
Date: 28 February 2013
Time: 2-4pm
Venue: Mini Auditorium, Government Engineering College, Barton Hill

This year’s science day was celebrated in our college on behalf of Department of science on 28 February 2013 commemorating the discovery of Raman Effect on Feb 28, 1928. The talk was delivered by Dr. Sibi K S, Assistant Professor in Physics. During the talk, students were taken to a journey through the visions of great scientists who are figuring out the beginning of our universe. In particle colliders, the scientists are trying to create the very cause that lead to our creation. The task is accomplished by setting up an experiment similar to Big Bang that occurred 15 billion years ago. Large Hardon Collider focus on finding the small piece of energy that binds quarks and other fundamental particles. The tiresome hard work, enormous will power and the amazing facts about Large Hardon Collider made students more excited when they came to know about plasma containment of Higgs Bosons.
The concepts of Physics are ever-changing. The simple fundamental laws of Physics are giving shape to complex theories that argue with our common sense reasoning. The ideas put forward by Albert Einstein, Neil Bohr, S N Bose and Peter Higgs paved path for infinite research options in science. It is not too long wait till we recreate the charm once again. It is to be noted that Impossibilities can only be known if we move one step forward from possibilities to impossibilities.
The Seminar concluded by 4pm. To summarize, the seminar touched various field like Concepts in Physics, Higgs Boson and Origin of universe, Large Hardon Collider etc..Around 300 students from S1 S2 as well as S3S4 braches attended the function. Few snap of the function are also added herewith.

Kidney cells successfully generated artificially

Singapore: Scientists in Singapore have successfully produced kidney cells under laboratory conditions, without using animals or cells from other organs.

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have successfully generated human kidney cells from human embryonic stem cells in vitro; the renal cells were produced under artificial conditions in the lab without using animals or organs, something that was not been possible until now.

IBN Executive Director Jackie Y. Ying said: 'This discovery has wide-reaching implications for in vitro toxicology, drug screening, disease models and regenerative medicine. In particular, we are interested in applying our technology to develop predictive in vitro drug testing and renal toxicity models as alternatives to animal testing.'

The scientists said that the kidney is a major target organ for drug-induced toxic effects. Therefore, it is important for pharmaceutical companies to find out early in the development phase whether their drugs would cause nephrotoxicity in humans.

However, animal models are of limited predictability, and there is currently no regulatory accepted in vitro assay based on renal cells to predict nephrotoxic effects, reports Science Daily.

'A major problem is the lack of suitable renal cells, which may now be resolved through our discovery,' said researcher Daniele Zink.
