Genetic engineering

There could soon be a non-toxic, longer-lasting and less-smelly alternative to DEET for repelling mosquitos. Scientists have created genetically engineered human skin bacteria that are unappealing to the irritating and disease-spreading insects.

"We can feed black soldier flies straight, dirty trash," says a team that's working to turn insects into landfill-clearing biomanufacturing machines that turn regular, dangerous or contaminated garbage into a range of high-value products.

Scientists have assembled the most complete woolly mammoth genome in 3D, thanks to an incredible “freeze-dried” specimen. With its DNA preserved in a glass-like state, chromosomes were found for the first time, and even gene expression patterns.

Engineered mRNA has turned cells into tiny biofactories, producing medications to successfully treat an inflammatory skin condition and two types of cancer, according to a new study. The tech paves the way for therapies in which patients’ bodies make their own drugs.

The first successful transplant of a genetically modified pig kidney into a human recipient is still being regarded as a medical milestone and success – even though the recipient, Rick Slayman, suddenly passed away over the weekend.

Medically, AI is helping us with everything from identifying abnormal heart rhythms before they happen to spotting skin cancer. But do we really need it to get involved with our genome? Protein-design company Profluent believes we do.

Bacteria-produced leather is already an eco-friendly alternative to its cow-derived counterpart, but it could soon be even eco-friendlier. Scientists have gotten the microbes to color the stuff themselves, eliminating the need for toxic dyes.

Analysis of Beethoven’s DNA has revealed that he had a low genetic predisposition for musical ability. The study highlights how making genetic predictions for individuals, including famous historical figures, can be fraught with danger.

We’re edging closer to seeing a live mammoth for the first time. Colossal Biosciences, a company dedicated to the controversial-but-unquestionably-cool goal of resurrecting extinct species, has made a breakthrough in creating elephant stem cells.

Thanks to a recent discovery regarding marine algae, scientists have developed crop plants that absorb a fuller spectrum of sunlight, resulting in better growth. The finding could also lead to increased production of biofuels.

In a true public service, potato scientists have flicked the 'off' switch on a genetic mechanism that causes cold-stored taters to produce carcinogenic acrylamide when cooked. It means that one of the world's greatest food groups could be made healthier.

The USDA has approved Light Bio's "Firefly Petunias," and the company is taking US$29 pre-orders on these remarkable gene-edited houseplants. They glow in the dark, making them a captivating home decor addition for science buffs.
