This session discuss the latest topics in Science and Technology
- Genetically Modified Foods/Crops
Genetically modified food is produced from plants which have had their genetic make-up in the lab.Scientists “cut and paste” a gene from another organism into a plant’s DNA to give it a new feature.This can be to increase yield or to allow the plant to exist in a more hostile environment than normal.Pro-GM scientists say this means cheaper more plentiful food but opponents argue we do not know the consequences of inter fearing with nature.
2. Stem Cells
Stem cells are the undifferentiated or blank cells found in the human body that have the potential to develop into many celltypes that can carry out different functions.
Autism is a complex disorder of brain.This is characterised by impaired social interaction, verbal and non-verbal communication,and restricted and repetitive disorder.It is a lifelong and developmental disability.
It is the term used to describe the gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change which is believed to change the Earth’s climate permanently.
5.Extra solar planet
Extra solar planet or exo solar planetsare planets outside our solar system that orbits a star other than our son.
Swiss astronomers Michael Mayor and Didier Queloz discovered the first exoplanet in 1995. Since then, the number of verified exoplanets has surpassed 200. There are a few different methods scientists use when trying to detect extrasolar planets.
Bird flu, or avian influenza, is a viral infection spread from bird to bird. Currently, a particularly deadly strain of bird flu — H5N1 — continues to spread among poultry in Egypt and in certain parts of Asia. Technically, H5N1 is a highly pathogenic avian influenza (HPAI) virus. It’s deadly to most birds.
7. Nano technology
It is the branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules.
