The first clinical trial comparing semaglutide and tirzepatide, two popular, injectable weight-loss drugs, has been published, examining their ability to reduce weight and waist circumference. And one clearly comes out on top.

Transplanting insulin-producing cells along with engineered blood-vessel-forming cells has successfully reversed type 1 diabetes in a new preclinical study. With further testing, the novel approach could one day cure the as-yet incurable condition.

Researchers have developed a gene therapy technology that uses magnetic fields to control specific brain circuits. In addition to Parkinson’s disease, the tech could be used to treat conditions as diverse as depression, obesity, and chronic pain.

Researchers have converted stomach stem cells into insulin-producing cells that respond to changes in blood glucose levels. The discovery could mean that one day, diabetics produce their own insulin instead of relying on injections.

Scientists have enlisted a new kind of helper to monitor the microbiomes of cities: the honeybee. Analyzing the debris from their hives has revealed much about what's happening at the microorganism level in cities around the world.

Male contraceptives have traditionally been limited to condoms and vasectomies. Now scientists have demonstrated a promising new method that takes the form of a pill that can be taken just before sex, greatly reducing fertility for 24 hours.

Two new studies in the journal Cell have reported on unexpected ways pain-sensing neurons in the gut can serve as more than just sensory alarm systems. The research suggests these neurons also can directly protect the gut from inflammatory damage.

A pair of new studies have reported novel links between fungal microorganisms and cancer. The research reports different types of tumors seem to harbor unique fungal populations, raising the possibility of new ways to diagnose and treat cancer.

Scientists at Weill Cornell Medicine have identified two new subtypes of prostate cancer. These new forms of the disease are resistant to usual treatments, but categorizing and studying them could lead to new therapies.

A new study is showing how fructose can alter cells in the small intestine, subsequently enhancing nutrient absorption and promoting weight gain. The research indicates excessive fructose consumption increases the body’s ability to absorb dietary fats.

Scientists in the US investigating the biological mechanisms behind fat burning have identified a protein that plays a key role in regulating metabolism, and demonstrated how blocking its activity can boost the process in mice.

We've been hearing a lot lately about how every person hosts their own unique population of viruses and bacteria, known as their microbiome. Well, according to a new international study, the same thing is true of cities.
