Scientists are using artificial intelligence (AI) to find new antibiotics. This gives people hope in the fight against dangerous bacteria. Some bacteria are very hard to kill. Doctors call these "superbugs." The World Health Organization says antibiotic resistance is one of the top 10 health problems in the world. About 1.27 million people die every year because of drug-resistant infections.
A big moment came in 2020. A team at MIT, led by Professor James Collins, found a new antibiotic called halicin. They used a computer program that learns from data. The program looked for chemicals that could kill bacteria in new ways. Halicin worked against many resistant bacteria. The team named it after HAL 9000, the computer from the famous film "2001: A Space Odyssey." The results appeared in the journal Cell.
Before halicin, progress was slow. No new type of antibiotic for common infections has been approved since the 1980s. An antibiotic is a medicine that kills bacteria. When bacteria stop responding to these medicines, doctors call this "resistance." Without working antibiotics, even small infections can become very dangerous.
In 2023, the MIT team worked with scientists at McMaster University in Canada. They found another antibiotic called abaucin. This drug targets a very dangerous superbug called Acinetobacter baumannii. It often spreads in hospitals and is hard to treat. The study was published in Nature Chemical Biology.
AI can study millions of chemicals very quickly. This saves years of work. Google DeepMind built a program called AlphaFold. It predicts the shape of proteins, which helps scientists design better medicines. DeepMind also started a company called Isomorphic Labs. In January 2024, it partnered with Eli Lilly and Novartis to develop new treatments.
Many investors are putting money into AI drug research. But scientists warn that computer discoveries must still pass many careful laboratory tests before they become real medicines.
