Scientists have discovered a sugar compound from deep-sea bacteria that can destroy cancer cells in a dramatic way. This natural substance, produced by microbes living in the ocean, causes cancer cells to undergo a fiery form of cell death, essentially making them self-destruct. In lab tests and in mice with liver cancer, the compound not only stopped tumors from growing, but also activated the immune system to fight back. This finding could pave the way for entirely new cancer treatments based on sugars from marine organisms.

A groundbreaking study involving genetic data from over five million people has uncovered how our DNA can predict obesity risk as early as childhood. The new polygenic risk score outperforms previous methods, helping to identify high-risk children before weight issues develop paving the way for early lifestyle interventions.

A surprising discovery from Emory University shows that psilocin, the active metabolite of psychedelic mushrooms, can delay cellular aging and extend lifespan. Human cells lived over 50% longer, and mice treated with psilocybin not only lived 30% longer but also looked and aged better.

What scientists once dismissed as junk DNA may actually be some of the most powerful code in our genome. A new international study reveals that ancient viral DNA buried in our genes plays an active role in controlling how other genes are turned on or off, especially during early human development. These sequences, originally from long-extinct viruses, have evolved to act like tiny genetic switches. Using new analysis tools and large-scale experiments, researchers discovered that certain viral DNA fragments are especially strong at activating genes and may even have helped shape what makes humans different from other primates.

A new UK study shows that vaccinating pregnant women against RSV has led to a staggering 72% drop in hospitalizations of newborns with severe lung infections. By passing virus-fighting antibodies to their babies, vaccinated mothers are helping shield infants during their most vulnerable early months.

What if mRNA vaccines could be made more powerful and less irritating? Scientists at the University of Pennsylvania have found a way to do just that—by tweaking a key molecule in the vaccine’s delivery system. Using a century-old chemical trick called the Mannich reaction, they added anti-inflammatory phenol groups to the lipids that carry mRNA into cells. The result? A new class of lipids that reduce side effects, boost gene-editing success, fight cancer more effectively, and supercharge vaccines like those for COVID-19. This breakthrough could change how we build the next generation of vaccines and therapies.

People in richer countries aren’t moving less — they’re just eating more. A new Duke study shows that diet, not laziness, is fueling the obesity epidemic across industrialized nations.
