Favorable mutations that went along with increased fruit size and other beneficial traits in tomato plants do not always play well together. A study published in Cell found that natural mutations in two important tomato genes that were selected for different purposes in breeding can cause extreme branching and reduce fruit yield when they occur in the same plant. The researchers used those genes to create a tomato plant that grows more tomatoes.

Humans are still evolving, So, where will evolution take us in 1,000 years?

A permanent cure for HIV infection remains elusive due to the virus's ability to hide away in latent reservoirs. But now, scientists show that they can excise HIV DNA from the genomes of living animals to eliminate further infection.

Using CRISPR technology, a team of researchers rewired stem cells' genetic circuits to produce an anti-inflammatory arthritis drug when the cells encounter inflammation. The technique eventually could act as a vaccine for arthritis and other chronic conditions.

Far to the right side of the decimal point—beyond milli, micro, nano, pico, and femto—lives the atto, the metric prefix representing 10-18. Slap it in front of a unit of concentration, such as molar, and it means that something exists in an extraordinarily small amount—think one part per quintillion. That’s the realm of SHERLOCK, a new diagnostic system that can detect attomolar levels of viruses in a sample and also distinguish Zika from its close relative, dengue. This exquisitely sensitiv...

Don’t like the seeds in tomatoes? You might be pleased to know that seedless ones have been created by gene editing.

Duke University researchers have come up with a way that use CRISPR/Cas 9 technology to quickly screen the non-coding portion of the human genome to better understand and eventually better treat various diseases

Can billions of dollars’ worth of high-tech research succeed in making death optional?

A team of researchers at Boston University has developed a new way to engineer mammalian cells that allows for programming them to behave in desired ways.

First results in viable human embryos reveal CRISPR’s biggest problem
