Scientists have figured out how two famously poisonous plants create chemicals with surprising medical potential. After tracking thousands of genes in wolfsbane and larkspur, they identified six enzymes needed to build a complex compound called atisinium. The team recreated the process inside tobacco plants, offering a sustainable way to produce and test these rare molecules in larger amounts.
A surprisingly small dose of exercise may deliver major health benefits for adults carrying excess fat around the waist. In a four-month trial involving 315 adults with central obesity, researchers found that completing 75 minutes of brisk interval walking in a single weekly session reduced body fat, trimmed waistlines, and improved cardiovascular fitness about as effectively as splitting the same exercise across three days.
Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more like an experimental cancer drug than an ordinary supplement. Early studies suggest it may damage vulnerable cancer cells, reduce treatment side effects, and possibly improve outcomes for some patients.
