A trial project by the Montreal Children's Hospital suggested that the use of medical hypnosis(催眠)can reduce pain and anxiety in patients. The project also resulted in a reduction in the amount of medicines used to perform medical-imaging imaging(医学影像) procedures.

"During the examination children don't move. It works perfectly. It's amazing," said Johanne L'Ecuyer, a medical-imaging technologist at the hospital.

The project was inspired by a French team from Rouen University Hospital Centre where examinations are done under hypnosis instead of general anesthesia(麻醉).

A French medical-imaging technologist-also a hypnotist — was invited to train a few members in the medical-imaging department of the children's hospital. In all, 80 examinations were conducted for the project between January and September, 2019, focusing on the imaging procedures that would cause anxiety.

Hypnosis is not a state of sleep: It is rather a modified(改变的)state of consciousness. The technologist will guide the patient to this modified state—an imaginary world that will disassociate itself more and more from the procedure that follows.

"The technologist must build up a story with the patient," Ms. L'Ecuyer said. "The patient is left with the power to choose what he wants to talk about. Do you play sports? Do you like going to the beach? We establish a subject that we will discuss throughout the procedure. "

Everything that happens next during the procedure must be related to this story — an injection (注射) becomes the bite of an insect; the heat on the skin becomes the sensation of the sun and a machine that rings becomes a police car passing nearby.

"The important thing is that the technologist associates what is happening outside the patient's body with what the patient sees in his head," Ms. L'Ecuyer said. "It requires creativity on the part of the technologist, imagination, a lot of patience and kindness."

The procedure appealed to the staff a lot when it was introduced in January. It spread like wildfire that someone from France was here to train the technologists," Ms. L'Ecuyer said. She added that she had a line of staff at her door wanting to take the training.

    It was one of those terribly hot days in Baltimore. Needless to say, it was too hot to do anything outside. But it was also scorching in our apartment. This was 1962, and I would not live in a place with an air conditioner for another ten years. So my brother and I decided to leave the apartment to find someplace indoors. He suggested we could see a movie. It was a brilliant plan.

    Movie theaters were one of the few places you could sit all day and—most important —sit in air conditioning. In those days, you could buy one ticket and sit through two movies. Then, the theater would show the same two movies again. If you wanted to, you could sit through them twice. Most people did not do that, but the manager at our theater. Mr. Bellow did not mind if you did.

    That particular day, my brother and I sat through both movies twice, trying to escape the heat. We bought three bags of popcorn and three sodas each. Then, we sat and watched The Music Man followed by The Man Who Shot Liberty Valance. We'd already seen the second movie once before. It had been at the theater since January, because Mr. Bellow loved anything with John Wayne in it.

    We left the theater around 8, just before the evening shows began. But we returned the next day and saw the same two movies again, twice more. And we did it the next day too. Finally, on the fourth day, the heat wave broke.

    Still, to this day I can sing half the songs in The Music Man and recite half of John Wayne and Jimmy Stewart's dialogue from The Man Who Shot Liberty Valance! Those memories are some of the few I have of the heat wave of 1962. They're really memories of the screen, not memories of my life.

According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.

Solar developers want to put up panels as quickly and cheaply as possible, so they haven't given much thought to what they put under them. Often, they'll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.

"Solar projects need to be good neighbors," says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. "They need to be protectors of the land and contribute to the agricultural economy." InSPIRE is investigating practical approaches to "low-impact" solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).

Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. "These pollinator-friendly solar farms can have a valuable impact on everything that's going on in the landscape," says Macknick.
