Hell will break loose, said a Nobel Prize winner. We will see baby factories, said others. That's how they talked about in vitro fertilization then. We can learn from that now.
💡 Fact-based optimistic news of the week
👩🏭 EU reaches lowest unemployment level in decades
EU unemployment has dropped from 11.3 percent in 2013 to 6 percent in 2023, the lowest level in several decades.
🐢 Sea turtles increase significantly in numbers
New studies show sea turtles are increasing in numbers at 28 locations worldwide. Only five sites show a decrease. On Sal Island off Africa, the number of loggerhead nests increased from 500 to 35,000 between 2008 and 2020.
👨💻 AI tutoring twice as effective as active classroom learning
Students using AI tutors learn more than twice as much in less time compared to traditional active classroom teaching. AI tutoring resulted in higher engagement and motivation among students.
✈️ First privately developed supersonic aircraft reaches Mach 1.1
Boom Supersonic's demonstration aircraft XB-1 reached a speed of 750 mph (Mach 1.122) at an altitude of 35 000 feet during its first supersonic flight. XB-1 is the first civil supersonic aircraft developed by a private company, without government or military support.
👩💻 AI can change people's false beliefs
Conversations with AI led 29 percent of participants to change their false beliefs. For some topics, certainty in false beliefs decreased by up to 41 percent. The effect was particularly strong for beliefs that participants had previously been very certain about.
✈️ New aircraft flies at supersonic speed without sonic boom
XB-1 has completed three supersonic flights without creating an audible sonic boom on the ground. Sound waves bend when traveling through air with different temperatures. Due to the colder temperatures at high altitude, the sound waves make a U-turn in the atmosphere.
