Takeaway meals contain more salt than advertised, study finds

Almost half of the takeaway meals tested contained more salt than advertised, with some dishes delivering nearly twice the recommended daily limit in a single serving. Surprisingly, classic fish and chips ranked among the lowest-salt options, while pasta, pizza, and curries were often the saltiest.

Scientists discover how colon cancer cells change identity to spread

Scientists have identified a molecular switch that may help explain how colorectal cancer becomes deadly. When levels of a gene-regulating factor called GATA6 drop, cancer cells can shed their normal identity and transform into highly adaptable, fetal-like cells capable of spreading through the bloodstream and establishing new tumors in the liver. The study suggests that this dangerous transition is driven less by new genetic mutations and more by changes in how genes are switched on and off.

5,000-year-old wolves found on remote island rewrite what we know about domestication

Scientists discovered ancient wolves on a tiny Baltic island where they could only have been brought by humans, suggesting an unexpectedly close relationship between people and wolves thousands of years ago. Evidence indicates the wolves were fed, possibly cared for, and may even have been managed or selectively bred long before modern ideas of domestication.

Johns Hopkins scientists develop nose spray DNA vaccine for tuberculosis

A new intranasal DNA vaccine may give the immune system an extra weapon against tuberculosis by targeting bacteria that can hide from antibiotics. In animal studies, it helped clear infections faster, reduced lung inflammation, and prevented relapse after treatment. The vaccine also enhanced the performance of drugs used against drug-resistant TB.
