Our brains are busier than ever before. We’re assaulted with facts, pseudo facts, jibber-jabber, and rumour, all posing as information. Trying to figure out what you need to know and what you can ignore is exhausting.

Our smartphones have become Swiss army knife–like appliances that include a dictionary, calculator, web browser, email, Game Boy, appointment calendar, voice recorder, guitar tuner, weather forecaster, GPS, texter, tweeter, Facebook updater, and flashlight.

But there’s a fly in the ointment. Although we think we’re doing several things at once, multitasking, this is a powerful and diabolical illusion.

“At least qualitatively, you see some shifts in content of dreams from the beginning of the pandemic into the later months,” Dr. Barrett said. “It’s an indication of what is worrying people most at various points during the year.”

Taken together, the papers also hint at an answer to a larger question: What is the purpose of dreaming, if any?

In recent years, brain scientists have argued that REM sleep — the period of sleep during which most dreaming occurs — bolsters creative thinking, learning and emotional health, providing a kind of unconscious psychotherapy.

The modern age of space exploration includes more than 70 countries with research institutes and space agencies. However, only a few of them have launch capability, the three largest being NASA in the United States, Roscosmos in the Russian Federation, and the European Space Agency. Back in the early days of the Space Age, there were only two space agencies, both vying for supremacy in space: the U.S. and the Soviet Union (predecessor to today's Russian Federation).

The Mir YearsThe most successful space station built by the Soviet Union flew from 1986 through 2001. It was called Mir, and assembled on orbit (much as the later ISS was). It hosted a number of crew members from the Soviet Union and other countries in a show of space cooperation.

Disaster in Soviet SpaceDisaster struck the Soviet program and gave them their first big setback. It happened in 1967, when cosmonaut Vladimir Komarov was killed when the parachute that was supposed to settle his Soyuz 1 capsule gently on the ground failed to open. It was the first in-flight death of a man in space in history and a great embarrassment to the program. Problems continued to mount with the Soviet N1 rocket, which also set back planned lunar missions. Eventually, the U.S. beat the Soviet Union to the Moon, and the country turned its attention to sending unmanned probes to the Moon and Venus.

Now financially secure, he decided to retire, escape the rat race, manage his own capital, and enjoy life. Within months, however, he reached out to me for psychological guidance. His new life was anything but bliss. No longer “in the game”, he felt rudderless. Free time became a source of boredom. To his dismay, he was feeling less physically healthy than when he was working crazy hour

We are wired as meaning-makers. If we cannot find positive sources of meaning, we often gravitate to negative ones, amplifying our social, emotional, and physical concerns. When Terence retired, he left the arena that sometimes pushed him to exhaustion, but that also provided his success and challenge.

Perhaps it is this overarching sense of purpose that enables money managers to weather the ups and downs of markets and invest renewed energy in their craft. Like any entrepreneur, these managers are driven, not just by sound business plans, but by a meaningful vision that allows them to pursue their plans with uncommon zeal.

n November, the musician Grimes made a bold prediction. “I feel like we’re in the end of art, human art,” she said on Sean Carroll's Mindscape podcast. “Once there’s actually AGI (Artificial General Intelligence), they’re gonna be so much better at making art than us.”

Artificial intelligence has already upended many blue collar jobs across various industries; the possibility that music, a deeply personal and subjective form, could also be optimized was enough to cause widespread alarm.

While obstacles like copyright complications and other hurdles have yet to be worked out, musicians working with AI hope that the technology will become a democratizing force and an essential part of everyday musical creation.

"We are in the beginning of a mass extinction and all you can talk about is money and fairy tales of eternal economic growth," the Swedish climate activist told the United Nations General Assembly on Monday. "How dare you?"

But convincing her to come to America wasn't easy. Thunberg refuses to fly because of the high levels of emissions from air travel. When she traveled to the World Economic Forum in Davos in January, she traveled by train. It took her 32 hours

"For more than 30 years, the science has been crystal clear, how dare do you continue to look away?"

Family. Friends. Love. Health. Freedom from war and natural disaster. Imagination. Community. A roof over our heads. Common decency. Hope. Opportunity. Memories. Financial stability. Favorite places. Days off work. Good weather. The golden age of television. Books. Music. Ice cream. Weekends. A friendly exchange. Something good that happened today. Something bad that didn't happen today. A good cup of coffee.

What keeps us from longer and more frequent visits to a grateful (and graceful) mental place is that we think about other things. In fact, we are wired to. Our primitive brains smartly evolved the capacity to quickly sense potential threats, to keep us safe. But in a post-saber-toothed-tiger era, we get easily annoyed, worried and distracted by a lot of extraneous noise.

Instead, we need more focus on the positive, And you don't have to set the bar high. Allow yourself to be thankful for the small, mundane things that give you joy and meaning, as well as the big ones. And don't try to gather heaps of blessings to count; a handful each day should do it.

Bangladesh is one of dozens of countries on the frontline of the climate emergency. Here global heating is no theoretical calamity of the future, but a very real, present danger.By 2050, it is predicted that one in seven people in the country will be displaced by climate breakdown. The sea level is projected to rise by 50cm over this time period and Bangladesh may lose approximately 11% of its land. Deadly storms are usually a question of when, not if.

For example, Mondal says that where once his peers would farm mainly rice, now they have taken to fishing. They use floating cages, allowing fish to breed in a secure area. Also, if water levels rise, the cages will too, so flooding is less of an issue.“About 20 to 30 years ago there would be a minimum of two crops per farming family but now because of waterlogging we have no more than one,” he says. Each cage is owned by one home and yields about 15,000 taka (£135) in additional income for the families a year. It’s also a consistent source of food, which could be vital if natural disaster hits. “In the last two years there was not too much rain but two years ago we were flooded,” Mondal says. “We worry about the future. If there is heavy rainfall the water could remain logged for a long period of time and we would have to take shelter on main road. We would stay there with our remaining belongings.”

A marine laboratory 85 miles southwest of New Orleans was designed to be a fortress against extreme weather. But it might be defeated by climate change.

It stands 18 feet above the ground on pillars with pilings that extend more than 100 feet underground. Its walls can withstand winds of up to 250 miles per hour.But the water is coming.

The assault from climate change is slower but more relentless than any storm, and will ultimately do more damage. It threatens researchers’ ability to study marine environments up close at a time when it’s more vital than ever to understand them.

When NASA's Mars 2020 rover lands on the Red Planet in February 2021, it will touch down in Jezero Crater, the site of a lake that existed 3.5 billion years ago. The next generation rover will build on the goals of previous robotic explorers by collecting the first samples of Mars, which would be returned to Earth at a later date.

"We're very much thinking about how Mars could be inhabited, how humans could come to Mars and make use of the resources that we have there in the Martian environment today," said Stack. "We send our robotic scouts first to learn about these other places, hopefully for us to prepare the way for us to go ourselves."

"Combining an understanding of the composition of the rocks, but also the very fine detail that we see in the rocks and the textures, can make a powerful case for ancient signs of life," Stack said. "We know that ancient Mars was habitable. But we haven't yet been able to show that we have signs, real signs, of ancient life yet. And with our instrument suite, we think we can make real advances towards that on the surface.

Metaphorical thinking is the wellspring of the human imagination — that virtuosic cognitive pivot of describing what a thing is through something it is not. “Everything which distinguishes man from the animals depends upon this ability to volatilize perceptual metaphors in a schema, and thus to dissolve an image into a concept,” Nietzsche proclaimed in his meditation on metaphor and reality.

Some of our mightiest metaphors draw on color to describe our perceptual and psychoemotional reality

It is a global emergency that has already killed on a mass scale and threatens to send millions more to early graves. As its effects spread, it could destabilise entire economies and overwhelm poorer countries lacking resources and infrastructure. But this is the climate crisis, not the coronavirus. Governments are not assembling emergency national plans and you’re not getting push notifications transmitted to your phone breathlessly alerting you to dramatic twists and developments from South Korea to Italy.

More than 3,000 people have succumbed to coronavirus yet, according to the World Health Organization, air pollution alone – just one aspect of our central planetary crisis – kills seven million people every year. There have been no Cobra meetings for the climate crisis, no sombre prime ministerial statements detailing the emergency action being taken to reassure the public. In time, we’ll overcome any coronavirus pandemic. With the climate crisis, we are already out of time

Pandemics and the climate crisis may go hand in hand, too: research suggests that changing weather patterns may drive species to higher altitudes, potentially putting them in contact with diseases for which they have little immunity.

CNN's Bill Weir looks at the parallels between coronavirus and the climate crisis

What's that worn-out phrase? Shouting into the wind? Well, after a decade of rising pollution, failed politics and worsening disasters, it seems the many, many of us who care about the climate crisis increasingly are shouting into the hurricane, if not the apocalypse.

On the cusp of 2020, the state of the planet is far more dire than in 2010. Preserving a safe and healthy ecological system is no longer a realistic possibility. Now, we're looking at less bad options, ceding the fact that the virtual end of coral reefs, the drowning of some island nations, the worsening of already-devastating storms and the displacement of millions -- they seem close to inevitable. The climate crisis is already costly, deadly and deeply unjust, putting the most vulnerable people in the world, often who've done the least to cause this, at terrible risk.

There are two numbers you need to understand to put this moment in perspective.The first is 1.5. The Paris Agreement -- the international treaty on climate change, which admittedly is in trouble, but also is the best thing we've got -- sets the goal of limiting warming to 1.5 or, at most, below 2 degrees Celsius of warming.
