Researchers at Maynooth University have developed a first-of-its-kind DNA computer that performs arithmetic operations using interacting DNA strands in water, without requiring continuous electricity. The breakthrough, published in Nature, demonstrates potential applications for energy-efficient computation, long-term data storage, and molecular systems for disease detection.
Professional cyclists reach speeds exceeding 100 km/h at events like the UCI Road World Championships in Montreal, but safety measures have not kept pace, resulting in at least 11 deaths in elite races this year. The sport faces tension between prioritizing speed and implementing safety reforms like GPS trackers, wider handlebars, and protective equipment, with divided opinions among riders about whether such measures compromise cycling's competitive spirit.
