Good evening. Here is the last one at the end of Friday.

1. US cities and businesses are evaluating vaccination mandates to help control the spread of the Delta variant.

Mayor Bill de Blasio called on New York businesses to require employee vaccinations and said he wanted to consider requiring vaccinations for people to participate in certain indoor activities, such as dining out. The vaccines remain effective against the worst consequences of Covid-19, including against the Delta variant.

2. Debate over vaccination mandates comes as Covid hospitalizations rise in 45 states. Some Florida hospitals have more Covid-19 patients than ever.

4. As if record temperatures weren’t enough, a “heating dome” is planned next week for much of the United States

Warm weather over the Montana region will move east across the northern and central plains over the next few days, according to the National Weather Service. By next week, the Great Plains and Midwest – along with parts of the East – will have highs 10 to 15 degrees above average. This heat, combined with high humidity, could make temperatures look like the 100’s in some areas.

Recent flooding around the world has shown that even the most recent metro systems are ill-equipped for an era of extreme weather conditions brought on by climate change.

Less than half an hour after the funeral, the American delegation left and returned to the United States because of the shots fired outside. Speaking at the airport after the delegation arrived, US Ambassador to the UN Linda Thomas-Greenfield said: “You deserve democracy, stability, security and justice. prosperity, and we are by your side in this time of crisis.

6. Sierra Leone has become the 23rd African country to abolish the death penalty. Almost half of the countries of the continent now outlaw this practice.

The decision was one more step in a goal long sought by civil society organizations and justice groups who view the death penalty as a holdover from Africa’s colonial history. A large majority of the 193 UN member states have either abolished the death penalty or do not practice it.

7. Meanwhile, 400 light years from Earth…

Astronomers have, for the first time, detected moons forming around a distant exoplanet (a planet outside the solar system). The discovery of a debris disk, gradually merging under its own gravity into moons as it orbits a Jupiter-like exoplanet, comes after years of observation. The results will help scientists answer one of the most puzzling questions in astronomy: How do planets and their moons form?

“It’s rare, especially in our field, that you see something so beautiful,” said one astronomer.

Also on the frontier of science: two decades after the human genome sequence project was unveiled with great fanfare, a team of 99 scientists have finally deciphered everything, giving us a new view of our DNA.

8. The Cleveland baseball team will become the Guardians after this season, abandoning the name “Indians” which he has used since 1915.

The team decided last year that they would no longer be called Indians because they are considered offensive to many Native Americans. The organization has followed the Washington football team, which dropped the Redskins name last year. The new name, which comes after months of deliberation, is a nod to an expanse of sculpture on a major bridge known as the Guardians of Traffic.

Baseballs don’t spin like they used to. Since Major League Baseball cracked down on sticky substances, spin rates on fastballs have dropped about 4%, strikeouts have declined, and the base percentage has increased. These pitchers had the biggest drop in turnover rates.

9. British Columbia researchers face a unique challenge: raise orphaned grizzly bears until they are large enough to be released into the wild.

Traditionally, grizzly mothers in North America will care for their offspring for at least two years. But a few cubs have ended up at the Northern Lights Wildlife Shelter, where a team is raising orphaned grizzly babies, fattening them, and teaching them life skills. Next spring, the bears will be fitted with battery-powered radio collars and tracked for several years in the hope that they can avoid conflicts with humans that led to the deaths of their mothers.

In other news from the animal kingdom, cockatoos in Sydney, Australia invented a technique for opening trash cans. As one bird learned from another, the skill quickly spread to the suburbs like a new dance step.
