Most frightening stories:

• A general rule across many types of wildlife is that their range after urbanization decreases to between one-half and one-third of what it was before urbanization.
• The Cuban sonic attacks are real. At least, the people who experienced them have real brain damage, even if we still don’t know what technology did the damage.
• Cape Town will probably not be the last major city to run out of water.

Most hopeful stories:

• There are some new ideas for quantifying ecological function. There is also new technology for mapping urban vegetation based on photos.
• You can read a book or take a free course on why Buddhist meditation may be really good for your brain and life. Also good for your brain would be curing Alzheimer’s disease, which has now been done in mice (although it seems to have caused them other problems).
• Quantum computers are getting closer…maybe.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

• I learned about a number of professional and academic models of animal movement and population ecology, along with some general theory on the subject.
• You can take a free class on how to start, or finish, writing a novel.
• SpaceX is planning to launch more than 4,000 small satellites.
