Though the technology promises seemingly innumerable ways to positively impact human life, gene editing is truly a double-edged sword, with nearly as many potentially negative consequences as benefits. Now, an advisory council to President Obama is urging the government to start creating countermeasures for the negative use of emerging biotechnologies.
This month, the President’s Council of Advisors on Science and Technology (PCAST) wrote a letter to President Obama recommending measures to address this potential for harm using new technologies. It advocates funding new research into antibiotic and antiviral drugs to combat resistance and having a $250 million fund for the stockpiling of vaccines.
The controversial laboratory tool known as CRISPR may have found a whole new world to conquer. Already the favored method of editing genes, CRISPR could soon become a low-cost diagnostic tool that could be used practically anywhere to determine if someone has an infectious disease such as Zika or dengue.
The controversial gene-editing tool may be able to identify infections reliably for pennies in places without electricity.
Technically, an animal could use RNA editing to change the nature of its proteins without completely altering the underlying DNA instructions. This makes the cephalopods’ ability to do it a very interesting phenomenon, but it’s unclear as to why the species requires this much RNA editing. Many of the edited proteins were found in the animals’ brains, which is why scientists think the editing and their brainpower could be linked.
More than any other species on earth, octopuses are particularly smart—they can solve puzzles, use tools, and communicate using color. Now scientists are saying they’re also capable of editing their RNA.
A team of scientists led by Joshua Rosenthal at the Marine Biological Laboratory and Noa Liscovitch-Braur and Eli Eisenberg at Tel Aviv University have discovered that octopuses and squid are capable of a type of genetic alteration called RNA editing. The process is rare among other species, leading scientists to believe that the cephalopods have evolved to follow a special kind of gene recoding.

Carriers of the mutation are essentially playing catch-up for their entire lives.
Any night owls reading this will be familiar with the struggle of constantly trying to fit into a morning person’s world. And now researchers say they’ve finally identified the genetic typo that causes this social jetlag.
A new study has revealed that many people who stay up late and struggle to wake up in the morning aren’t lazy, their internal clock is simply genetically programmed to run between 2 and 2.5 hours slower than the rest of the population, thanks to a mutation in a body clock gene called CRY1.
China has made the precision medicine field a focus of its 13th five-year plan, and its companies have been embarking on ambitious efforts to collect a vast trove of genetic and health data, researching how to identify cancer markers in blood, and launching consumer technologies that aim to tap potentially life-saving information. The push offers insight into China’s growing ambitions in science and biotechnology, areas where it has traditionally lagged developed nations like the United States.
Precision medicine a focus of latest five-year plan.
