A new drug, Sorfequiline, has shown promising results in trials for treating tuberculosis (TB), potentially increasing cure rates and reducing treatment duration. Last year, TB affected an estimated 10.7 million people globally, leading to 1.23 million deaths.

The bursera plant has developed a unique defense mechanism, capable of shooting a high-pressure stream of toxic liquid resin up to 1.5 meters to deter insects. This resin is not only repellent but can also solidify, trapping smaller insects. Over millions of years, some beetles have evolved strategies to disarm this defense, showcasing a fascinating evolutionary arms race between the plant and its insect attackers.
