There are letters to the editor from Scientific American. DedicATED reader. I have been reading for a long time. I have been a subscriber for ninety years. It is one of the richest issues of all time. I gave it to my daughter, the mother of a 13-year-old, so she could read the articles on teaching kids to spot misinformation in the media. The new research on the skills of Neandertals was written by David W. Frayer and Davorka Radovi and I enjoyed reading it. You reviewed two books in Recommended. There is a woman in the White River Junction, Vt. area. There are sources of confusion. A topic that is dear to my heart, but one for which I have little hope, is covered in the article " Schooled in lies" by Melinda Wenner Moyer. Students in my high school chemistry class did a project on the safety of the artificial sweetener aspartame. Assessing the validity of primary information is not something most people can do. I may be able to do more than other people, but there are many topics that I am not qualified to analyze. We have to pick a source whose analysis we accept. The students were asked why they chose to accept, to trust, one source or another. The American Cancer Society and the Food and Drug Administration are some of the institutions that my stronger students choose to accept. I wish I had done a better job of collecting the data, but I think that those who prosper in a system tend to accept the system as trustworthy. People who don't prosper so well tend to be more skeptical of the system, preferring to accept their own experiences or those of others known to them. That the world is messy and that's okay is what makes our choice of whose perspective to trust so challenging. Questions will always be asked of one source or another. We might be able to get to the point where students recognize the mess and realize that they might be wrong. Skokie, Ill. is home to Russell Kohler. Nuclear defense. I agree that nuclear plants have not lived up to their promise so far. They are too expensive and take too long to build. High electricity costs are caused by them. There is an urgent need to do something. Multiple smaller modular plants that don't take so long to build are one of the new nuclear technologies. Fossil fuels will never be replaced with renewable fuels. Nuclear fusion is a long way away. The political will is needed to put a price on carbon and build smaller and safer reactor. It is not possible to give up. Steve Muller is in Colorado Springs. You can sign up for Scientific American's newsletters. Nuclear energy development should be a top priority. I know how much effort is required for the completion of nuclear electricity stations. Development engineering and construction time must be planned now. We need to use the sustainable technology of wind and photovoltaic farms. Adding a federal tax on gasoline and reducing dependence on transportation via Eisenhower-era highways would help. Don Finn is a man. The city of Palos Park is in Illinois. Spacetime exploration. When I was a high school student in Los Angeles in 1965, I read about two students at the University of California, Los Angeles, who were challenged by their science teacher to come up with a theory on time. The two students sat in a vacant parking space for an hour after they deposited their coins in a parking meter. In order to occupy space, you must first have time, concluded the report written to their professor. Douglas Weiskopf is from Burbank, Calif. The solution is in. Kyle Wiens wrote a piece on how Congress should uphold the right to repair electronic devices. Readers interested in getting involved with hands-on right to repair can check out the Fixit Clinic or Repair Cafe. Volunteer repair coaches help others learn how to fix their broken stuff. Over the last couple of years, these clinics have been happening virtually, with global participants engaging in fun and informative repair activities. We try to work together to diagnose and repair appliances, electronics, and so on, but we are worried that manufacturers will make this more difficult, if not illegal. The man is Wayne Selzer.

There is truth in labeling.
The book is called " Inside America's Militias". The media and academics need to stop referring to these groups asmilitias. It gives them legitimacy that they don't have and reinforces their irrational belief that they are like the militias that won the Revolutionary War. It would be more apt to call them politically armed groups. It's important to have labels.

There is real importance.
Much is made about the importance of the Amazon rain forest, which serves as a diminishing but necessary carbon sink and a source of life-giving oxygen. Less attention is given to the boreal forests in northern latitudes, which encompass several regions of North America, Russia and Sweden.
The boreal forests are as important as the tropical forests at lower latitudes in terms of sequestering carbon dioxide and contributing oxygen to our atmosphere. Logging, clearing land for agriculture, road building and especially mining are activities that are often overlooked in discussions about global warming.
