Explaining genetic modification research

What do bananas and cavoodles have in common? They're both lovely, yellowy and have been produced by genetic manipulation.

Understanding the genomic modifications in transgenic papaya

The transgenic papaya "SunUp" was developed in the 1990s and was widely publicized because of its ability to resist the papaya ringspot virus. Although researchers had identified the genomic sequence of SunUp by 2008, it ...

'Yoyo stars' found responsible for off-center cosmic bubbles

Astronomers have developed a new model to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion Nebula shows that its off-center bubble of ionized gas was caused by a massive ...

Consumers embrace milk carton QR codes, may cut food waste

The "use-by" and "best-by" dates printed on milk cartons and gallon jugs may soon become a thing of the past, giving way to more accurate and informative QR codes. A new Cornell University study finds that consumers will ...

New 'CRISPR-Combo' method boosts genome editing power in plants

Ten years ago, a new technology called CRISPR-CAS9, made it possible for scientists to change the genetic code of living organisms. As revolutionary as it was, the tool had its limitations. Like the first cell phones that ...

Sea corals are source of sought-after 'anti-cancer' compound

The bottom of the ocean is full of mysteries but scientists have recently uncovered one of its best-kept secrets. For 25 years, drug hunters have been searching for the source of a natural chemical that had shown promise ...

How three mutations work together to spur new SARS-CoV-2 variants

Like storm waves battering a ship, new versions of the SARS-CoV-2 virus have buffeted the world one after another. Recently, scientists keeping tabs on these variants noticed a trend: Many carry the same set of three mutations. ...

Code

A code is a rule for converting a piece of information (for example, a letter, word, phrase, or gesture) into another form or representation (one sign into another sign), not necessarily of the same type.

In communications and information processing, encoding is the process by which information from a source is converted into symbols to be communicated. Decoding is the reverse process, converting these code symbols back into information understandable by a receiver.

One reason for coding is to enable communication in places where ordinary spoken or written language is difficult or impossible. For example, semaphore, where the configuration of flags held signaller or the arms of a semaphore tower encodes parts of the message, typically individual letters and numbers. Another person standing a great distance away can interpret the flags and reproduce the words sent.
