With Russia’s invasion of Ukraine and the specter of nuclear weapon use, Earth crept its closest to Armageddon, a science-oriented advocacy group said, moving its famous “Doomsday Clock” up to just 90 seconds before midnight.

“We are really closer to that doomsday,” former Mongolian president Elbegdorj Tsakhia said Tuesday at the Bulletin of Atomic Scientists annual announcement rating how close humanity is from doing itself in. He and former Ireland President Mary Robinson joined scientists to underscore what they consider a gathering of several existential threats, with Russian leader Vladimir Putin's actions and words chief among them.

“People and scientists are warning us and we have to wake up now,” he said.

The advocacy group started in 1947 to use a clock to symbolize the potential and likelihood of people doing something to end humanity. It moved the clock 10 seconds closer than last year, making it the closest it has ever been to striking 12. It's been as much as 17 minutes from midnight after the end of the Cold War but in the past few years, the group has changed from counting down the minutes to midnight to counting down the seconds.

Doomsday has not happened yet.

“We are sending a message that the situation is becoming more urgent,” Bulletin President Rachel Bronson said at the online announcement. “Crises are more likely to happen and have broader consequences and longer standing effects.”

And to emphasize the effect that Russia’s invasion of Ukraine had on moving closer to theoretical doomsday, the group said it was also announcing the clock movement in the Russian and Ukrainian languages for the first time.

“Putin has repeatedly raised the specter of nuclear use,” said Steve Fetter, dean of the graduate school and a public policy professor at the University of Maryland.

“Putin has given no indication that he's willing to accept defeat,” Fetter said. “He might make desperate moves if no other options are available that he regards as acceptable.”

Scientists and activists at the Bulletin announcement also mentioned nuclear weapon proliferation in China, Iran increasing its uranium enrichment, missile tests in North Korea, future pandemics from animal diseases, pathogens from lab mistakes, “disruptive technologies” and worsening climate change as other existential threats to humanity.



Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
