What is gene gun?

Gene Gun

A gene gun is a device used to introduce genetic material to cells through the use of tiny DNA-coated particles fired at high velocity into a cluster of cells. Gene guns are used in laboratory settings to conduct research, develop new products, and tag samples of materials.

The gene gun was created as a new way of proceeding with gene transformation of grains in response to the difficulty of getting bacteria across grain cell walls. It was designed by John Sanford at Cornell University in 1987 and made introducing new genetic material into plant cells much easier than previous methods, such as the use of viruses or agrobacterium.

What is neurolaw?


Neurolaw is a new discipline that studies the effect of neuroscientific evidence on law and legal cases. It also sets standards as to how nueroscience should be used in relation to the legal system. It is believed that neurolaw could play a more decisive role in cases involving rape and murder, where detection of the truth becomes imperative. Proponents of neurolaw say neuroscience could have a huge impact on guilt, quantum of punishment, and detection of lies and biases.

Why dimpled or unsmooth balls used in golf game?

The reason why golf balls have dimples is a story of natural selection. Dimples maximize the distance golf balls travel. Dimpled balls travel up to four times farther than smooth-surfaced golf balls.
In the early days of golf, smooth-surfaced balls were used until golfers discovered that old, bumpy balls traveled longer distances. The science of aerodynamics

What is Big Crunch theory?

This theory says the universe will one day stop expanding. Then, as gravity pulls on matter, the universe will begin to contract, falling inward until it has collapsed into a super-hot, super-dense singularity. The universe is like a giant souffle. It starts out small, expands as it heats up, and eventually, as the souffle cools, begins to collapse. Big Crunch is the consequence

What is carbon dating?

Carbon dating or radiocarbon dating is a method to determine the age of plants and fossils or is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to determine the age of carbonaceous materials up to about 58,000 to 62,000 years. Carbon has three naturally occurring isotopes,
