description

There is no such thing as a truly original idea! New science is built on the work of the past. Knowing the history is essential to develop a better insight for future breakthroughs. The mastery of knowledge developed by previous researchers aides in choosing the right path and quickening the process to success. Scientific knowledge continues to grow and overflow. Peer reviewed scientific literature continues to be the prime resource for accessing worldwide scientific knowledge. This presentation will cover how today’s biological research is benefitting from connecting and combining these borrowed ideas.

“The guy who invented

the first wheel was an idiot.

The guy who invented

the other three,

HE was a genius.”

Woody Guthrie – American Folk

Musician (1912–1967)

“The words are the

important thing. Don’t worry about tunes.

Take a tune, sing high when

they sing low, sing fast when

they sing slow, and you’ve

got a new tune.”

This Land is Your Land adapted from an old gospel song Oh My

Loving Brother

Henry Ford – American Industrialist

(1863–1947)

“I invented nothing new.

I simply assembled the discoveries of other men behind whom were centuries of work … progress happens when all the factors that make for it are ready and then it is inevitable.”

Mark Twain, American Author

(1835 – 1910)

“All ideas are second-hand,

consciously and unconsciously drawn from a million outside sources. We are constantly littering our literature with disconnected sentences borrowed from books at some unremembered time and now imagined to be our own.”

The Origin of a Creative Idea

Step One: Defining

Define the problem you are trying to solve

Step Two: Borrowing

Borrow ideas from places with a similar problem

Step Three: Combining

Connect and combine these borrowed ideas

Curation: Origin

“Curation, broadly interpreted, is about maintaining and adding value

to, a trusted body of digital information for current and future use.”

Library Museum Biological Research

Today

A typical primary care doctor

must stay abreast of

approximately

10,000 diseases and syndromes,

3,000 medications, and

1,100 laboratory tests.

standard can be produced

1. Ad hoc method

3. Government-mandate method

“If I have seen further it is by standing

Pharmacophore:

Looking for common features

Pharmacophore: “ a set of structural features in a molecule that is

recognized at a receptor site and is responsible for that molecule’s

biological activity.”

Pharmacophore Features

Certain features are vectors with a directional component

- Eg., hydrogen bond donors and acceptors

- These are composed of two points.

Most features are represented by a single point

- For example, hydrophobic center

There are limits on the number of points and features.
