Scientists capture two DNA strands zipping together for the first time
Scientists have directly observed how two negatively charged DNA molecules can pair up despite normally repelling each other. Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a molecular zipper. The discovery confirms a theory proposed two decades ago and could help researchers understand DNA interactions involved in cancer and other cellular processes.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago. Every link goes to the original publisher so you can read the full study or press release yourself.
If today's breakthrough story sparked something, a live 1-on-1 tutor can take you from curious to competent. First lesson guaranteed or your money back.
