White House staff working in-person are no longer tested for Covid-19 every day as those on campus have been increasingly vaccinated, a recent change to testing protocol, according to an administration official familiar with the process.

"Our testing protocol is informed by a range of factors, including an employee's vaccination status, and is only one of a host of measures in place to mitigate risk in the workplace," Munoz said.

Masks were mandated, Covid-19 testing was expanded and room capacity measures were put in place. Zeke Miller, the president of the White House Correspondents' Association, said in January that "things are different" at the White House now that Biden has taken charge, adding that "all of those things make that workplace a little bit safer."

The economic orthodoxy has long been that governments should try to balance their books and leave all the heavy lifting in managing their economies to central banks.

“we are all Keynesians now”

 The natural sciences reflect a concerted effort on the part of humans to search for understanding of the world. Like any other human endeavour, the development of scientific knowledge forms a web with more practical, even everyday, interests and concerns. The natural sciences are recognized as a model for knowledge owing to many factors, prime among which is their capacity to explain and make precise predictions

If natural sciences are defined as investigating the natural world, what is meant by “natural” or “nature” in this context? What difference might it make to scientific work if nature were to be regarded as a machine (for example, as a clockwork mechanism) or as an organism (such as in some interpretations of the Gaia hypothesis)? How useful are these metaphors?Does scientific language and vocabulary have primarily a descriptive or an interpretative function? Consider here expressions such as “artificial intelligence”, “electric current”, “natural selection” and “concentration gradient”.

If you've ever stayed in a relationship too long or stuck with a project that was going nowhere, you're not alone.

If you've ever stayed in a relationship too long or stuck with a project that was going nowhere, you're not alone.

It's called the "sunk costs" phenomenon, where the more resources we sink into an endeavor, the likelier we are to continue -- even if we sense it's futile.

Leibowitz moved to the Arctic to learn how Scandinavians don’t just survive but thrive during the long winters. The sun doesn’t rise at all in the far north for two months, but she noted that Norwegians have comparable rates of seasonal depression to those of us in the United States.

Her research found that a positive mind-set — the result of reframing — is associated with well-being, greater life satisfaction and more positive emotions like pleasure and happiness. Accepting the inevitable helps, too — as a yoga teacher once told my class, “Let go or be dragged down.

“People who see stressful events as ‘challenges,’ with an opportunity to learn and adapt, tend to cope much better than those who focus more on the threatening aspects — like the possibility of failure, embarrassment or illness,”

Thirty years were added to average life expectancy in the 20th century, and rather than imagine the scores of ways we could use these years to improve quality of life, we tacked them all on at the end. Only old age got longer.

As a result, most people are anxious about the prospect of living for a century. Asked about aspirations for living to 100, typical responses are “I hope I don’t outlive my money” or “I hope I don’t get dementia.”

Each generation is born into a world prepared by its ancestors with knowledge, infrastructure and social norms. The human capacity to benefit from this inherited culture afforded us such extraordinary advantages that premature death was dramatically reduced in a matter of decades. Yet as longevity surged, culture didn’t keep up

On the face of it, “Feline Philosophy” would seem like a departure for Gray — a playful exploration of what cats might have to teach humans in our never-ending quest to understand ourselves. But the book, in true Gray fashion, suggests that this very quest may itself be doomed. “Consciousness,” he writes, “has been overrated.”

We get worried, anxious and miserable. Our vaunted capacity for abstract thought often gets us (or others) into trouble. We may be the only species to pursue scientific inquiry, but we’re also the only species that has consciously perpetrated genocides. Cats, unlike humans, don’t trick themselves into believing they are saviors, wreaking havoc in the process.

Humans like to think of themselves as special, in other words, but what makes us special also, not infrequently, makes us worse

it turns out that the colors that our language routinely obliges us to treat as distinct can refine our purely visual sensitivity to certain color differences in reality, so that our brains are trained to exaggerate the distance between shades of color if these have different names in our language.

some languages, like Matses in Peru, oblige their speakers, like the finickiest of lawyers, to specify exactly how they came to know about the facts they are reporting. You cannot simply say, as in English, “An animal passed here.” You have to specify, using a different verbal form, whether this was directly experienced (you saw the animal passing), inferred (you saw footprints), conjectured (animals generally pass there that time of day), hearsay or such. If a statement is reported with the incorrect “evidentiality,” it is considered a lie.

For many years, our mother tongue was claimed to be a “prison house” that constrained our capacity to reason. Once it turned out that there was no evidence for such claims, this was taken as proof that people of all cultures think in fundamentally the same way. But surely it is a mistake to overestimate the importance of abstract reasoning in our lives. After all, how many daily decisions do we make on the basis of deductive logic compared with those guided by gut feeling, intuition, emotions, impulse or practical skills? The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies.

Photographic memory, eidetic memory, Hyperthymesia, Highly Superior Autobiographical Memory, perfect recall, there are a number of labels to choose from when discussing formidable memory prowess.

However, the idea that someone has a “flawless” memory, is able to remember everything from any aspect of their lives in great and accurate detail, is far from confirmed by available scientific evidence.

when you ask more personal life events that things get tricky. If someone describes the scene at their 7th birthday and what presents they got, how you are supposed to confirm if they’re remembering it correctly?

IBM estimates that 90% of the world's online data has been created just in the past two years. What's more, it has made information more accessible than ever before.

However, rather than enhancing knowledge, the internet has produced an information glut or "infoxication".

Furthermore, since online content is often curated to fit our preferences, interests and personality, the internet can even enhance our existing biases and undermine our motivation to learn new things.

The human brain is more complex than any other known structure in the universe.

Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.

The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Animals such as elephants, dolphins, and whales actually have larger brains, but humans have the most developed cerebrum. It's packed to capacity inside our skulls, with deep folds that cleverly maximize the total surface area of the cortex.

The Importance of a Positive Classroom

Simply put, students learn better when they view the learning environment as positive and supportive

A positive environment is one in which students feel a sense of belonging, trust others, and feel encouraged to tackle challenges, take risks, and ask questions

Nobody really needs smartphone-operated bike locks or propane tanks. And they certainly don’t need gadgets that are less trustworthy than the “dumb” ones they replace, a sin many smart devices commit. But people do seem to want them—and in increasing numbers.

Why? One answer is that consumers buy what is on offer, and manufacturers are eager to turn their dumb devices smart. Doing so allows them more revenue, more control, and more opportunity for planned obsolescence. It also creates a secondary market for data collected by means of these devices. Roomba, for example, hopes to deduce floor plans from the movement of its robotic home vacuums so that it can sell them as business intelligence.

And the more people love using computers for everything, the more life feels incomplete unless it takes place inside them.

Urban airports like Boston’s Logan thought they had silenced noise issues with quieter planes. Now complaints pour in from suburbs 10 to 15 miles away because new navigation routes have created relentless noise for some homeowners.

It turns out engines aren’t the major culprit anymore. New airplanes are much quieter. It’s the “whoosh” that big airplanes make racing through the air.

Computer models suggest slowing departures by 30 knots—about 35 miles an hour—would reduce noise on the ground significantly.

The National Rifle Association has called for "additional regulations" on bump-stocks, a rapid fire device used by the Las Vegas massacre gunman.

"I think we are on the verge of a breakthrough when it comes to sensible gun policy," he told reporters.

Republican congressional leadership may try to clamp down on the proceedings, but there's a chance other proposals -like limits on magazine capacity, military-style rifle features and new background check requirements - could come up for consideration.

There is good evidence a midlife decline in life satisfaction is real. Population surveys typically find both women and men report the lowest satisfaction in middle age. The Australian HILDA survey locates the lowest life satisfaction at age 45, and the Australian Bureau of Statistics singles out the 45-54 age bracket as the glummest.

Middle age may be dislocating for some but there is little evidence it is usually a period of crisis and despondency. Psychologically speaking, things tend to get better. If there is a small dip in how people evaluate their lot -- even if it is objectively no worse than before -- this is understandable. Our attention shifts from time past to time left, and that requires a process of adjustment.

In one US study, one-third of people in their 70s defined themselves as middle-aged. This research accords with the finding middle-aged people tend to feel one decade younger than their birth certificate.

We might not be conscious of how we interpret the world, because our beliefs are ingrained and habitual.

we can learn to bring our unconscious life philosophy to consciousness by asking ourselves questions.

That might sound incredibly simplistic and over-optimistic. Some philosophers, psychologists and neuroscientists would argue that our capacity to choose a path in life is severely constrained by our genes, our childhood, our circumstances.

To clarify death further, we will need to say a bit about the nature of life, and ask whether life can be suspended or restored, and how it relates to our continued existence.

we will be puzzled about what is entailed by the ending of life, that is, death.

‘Death’ can refer to either.

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.
