The Best News of Last Week
1. âWe are just getting startedâ: the plastic-eating bacteria that could change the world
In 2016, Japanese scientists Oda and Hiraga published their discovery of Ideonella sakaiensis, a bacterium capable of breaking down PET plastic into basic nutrients. This finding marked a shift in microbiology's perception, recognizing the potential of microbes to solve pressing environmental issues.
France's Carbios has successfully applied bacterial enzyme technology to recycle PET plastic waste into new plastic products, aligning with the French government's goal of fully recycling plastic packaging by 2025.
2. HIV cases in Amsterdam drop to almost zero after PrEP scheme
According to Dutch AIDS Fund, there were only nine new cases of the virus in Amsterdam in 2022, down from 66 people diagnosed in 2021. The organisation claimed that 128 people were diagnosed with HIV in Amsterdam in 2019, and since 2010, the number of new infections in the Dutch capital has fallen by 95 per cent.
3. Cheap and drinkable water from desalination is finally a reality
In a groundbreaking endeavor, engineers from MIT and China have designed a passive solar desalination system aimed at converting seawater into drinkable water.
The concept, articulated in a study published in the journal Joule, harnesses the dual powers of the sun and the inherent properties of seawater, emulating the oceanâs âthermohalineâ circulation on a smaller scale, to evaporate water and leave salt behind.
4. Worldâs 1st drug to regrow teeth enters clinical trials
The ability to regrow your own teeth could be just around the corner. A team of scientists, led by a Japanese pharmaceutical startup, are getting set to start human trials on a new drug that has successfully grown new teeth in animal test subjects.
Toregem Biopharma is slated to begin clinical trials in July of next year after it succeeded growing new teeth in mice five years ago, the Japan Times reports.
5. After Decades of Pressure, US Drugmaker J&J Gives Up Patent on Life-Saving TB Drug
In what can be termed a huge development for drug-resistant TB (DR-TB) patients across large parts of the world, bedaquiline maker Johnson and Johnson said on September 30 (Saturday) that it would drop its patent over the drug in 134 low- and middle-income countries (LMICs).

7. âStaggeringâ green growth gives hope for 1.5C, says global energy chief
The prospects of the world staying within the 1.5C limit on global heating have brightened owing to the âstaggeringâ growth of renewable energy and green investment in the past two years, the chief of the worldâs energy watchdog has said.
Fatih Birol, the executive director of the International Energy Agency, and the worldâs foremost energy economist, said much more needed to be done but that the rapid uptake of solar power and electric vehicles were encouraging.
