Researchers have identified specific regions of the human genome connected to cannabis use, which means the propensity to get addicted to weed may be encoded in our DNA.

It’s not often that space throws something entirely new at you, but in 2019 astronomers discovered a completely unknown phenomenon they called odd radio circles (ORCs). Now, more data may have revealed just how these rare objects form.

Like weeds that grow back if you don’t remove the roots, cancer can keep returning thanks to stem cells. A new “designer” DNA molecule eradicates these cancer stem cells, with tests in mice showing promising early results in preventing relapse.

Vitamin C supports the immune system, plays a key role in wound healing, and may even aid in recovery from COVID-19. So, how do you do know if you're getting enough of it? Well, a wearable sweat-analyzing sensor could soon tell you.

Corals serve as a host to algae, which produces sugars that the corals consume. Now, scientists have 3D-printed coral that's even more algae-friendly than its natural equivalent – it could help limit coral bleaching, and provide a source of biofuel.

For people afflicted with multiple sclerosis (MS), it can be difficult to quantify how their condition fluctuates over short periods of time. According to a new study, though, an existing device is able to detect subtle changes that might be missed.

Creative new treatments for superbugs are sorely needed, and now researchers at UCSD have developed a concept that’s just crazy enough to work – self-propelling “microvehicles” that lure bacteria into a trap, then kill them.

In lab tests, researchers have identified a cellular “switch” that could be turned off to clear out HIV lying dormant inside cells.

Humans have been tinkering with evolution for millennia, but new research might make the process a bit more direct. Biologists at the University of California San Diego have successfully used the CRISPR gene-editing tool to control genetic inheritance in mice for the first time.

​Earlier this year, we heard how scientists from UC San Diego had developed a flexible ultrasound patch that allows users to see the inner structure of irregular-shaped objects. Well, now they've made one that measures a patient's blood pressure from deep within the body.

​Acne sufferers, take heart. Scientists from UC San Diego are now in the process of developing what could – eventually – be a vaccine for the skin disease. Not only may it drastically reduce inflammation, but it's also unlikely to have the side effects of currently-used medications.

​It's never a good thing when donated human blood – or even the blood in our bodies – is infected with bacteria. Scientists at the University of California San Diego, however, are developing a means of removing such blood-borne microbes using tiny ultrasound-powered robots.
