Staying Smarter: Do you know what the summer slump is?
The summer learning slump happens when you do not have enough learning opportunities over the summer vacation to maintain your current level of knowledge.
The summer slump occurs when you stop learning new skillsand practicing using the skills that you gained the past year.
You can prevent the summer slump by doing at least 3 of the following activities during the summer vacation.

NASA Names Artemis II Crew for Mission to Fly by Moon in 2024
Astronauts are expected to travel 6,400 miles beyond the moon’s far side before speeding back to Earth
NYTIMES: Science April 3, 2023
Humans have not ventured more than a few hundred miles off the planet since the return of Apollo 17, NASA’s last moon mission, in 1972. After Artemis’s experience on the moon, NASA hopes to chart a path to putting humans on Mars, while scientists expect to use what is found there to answer questions about how the solar system formed.
Astronauts in 2023 are much different from those when the United States was in a race to beat the Soviet Union to the moon. During the Apollo program, 24 astronauts flew to the moon, and 12 of them stepped on the surface. All of them were Americans. All of them were white men, many of whom were test pilots.
They are Reid Wiseman, the mission’s commander; Victor Glover, the pilot; Christina Koch, mission specialist; and, Jeremy Hansen, also a mission specialist. The first three are NASA astronauts, while Mr. Hansen is a member of the Canadian Space Agency.
“When we were selecting astronauts back then,” Mr. Glover said in an interview, “we intended to select the same person, just multiple copies.”
Ms. Koch will be the first woman to venture beyond low-Earth orbit, and Mr. Hansen, as a Canadian, the first non-American to travel that far.
Mr. Hansen noted that the United States could have undertaken the Artemis missions by itself but instead chose to pull together an international collaboration with Canada and the European Space Agency. That agreement reserved a seat for a Canadian astronaut on Artemis II. “All of Canada is grateful for that global mind-set and that leadership,” Mr. Hansen said.

Site selection for Canada’s Nuclear Waste Geological Repository – Canada stands on the brink of a momentous decision: selecting a final resting spot for its spent nuclear fuel waste
Canada: An impending decision despite roadblocks
Canada generates around 15 percent of its electricity generation from 19 nuclear reactors at four power plants—all of which are of the CANDU (Canada Deuterium Uranium) design, a heavy-water reactor that uses natural (unenriched) uranium fuel (National Energy Board 2018). Canada’s four nuclear power plants, three of which are located in Ontario and one in New Brunswick, have produced a stockpile of approximately 3.1 million spent nuclear fuel bundles that increases at a rate of about 90,000 bundles per year (Gobien and Ion 2021). If all the currently operating plants live out their licensed lifetimes, Canada estimates that it will have to dispose of 5.5 million bundles.
