For all its forward-thinking companies and liberal social and environmental policies, the state has mostly put higher-value jobs and industries in expensive coastal enclaves, while pushing lower-paid workers and lower-cost housing to inland areas like the Central Valley. This has made California the most expensive state — with a median home value of $550,000, about double that of the nation — and created a growing supply of three-hour “super commuters.” And while it has some of the highest wages in the country, it also has the highest poverty rate based on its cost of living, an average of 18.1 percent from 2016 to 2018. That helps explain why the state has lost more than a million residents to other states since 2006, and why the population growth rate for the year that ended July 1 was the lowest since 1900.“What’s happening in California right now is a warning shot to the rest of the country,”

“It’s a warning about income inequality and suburban sprawl, and how those intersect with quality of life and climate change.” You can see this in California economic forecasts for 2020, which play down the threat of a global trade war and play up the challenge of continuing to add jobs without affordable places for middle- and lower-income workers to live.

Earlier this month, a Chinese tech giant quietly dethroned Microsoft and Google in an ongoing competition in AI. The company was Baidu, China’s closest equivalent to Google, and the competition was the General Language Understanding Evaluation, otherwise known as GLUE.

GLUE is a widely accepted benchmark for how well an AI system understands human language. It consists of nine different tests for things like picking out the names of people and organizations in a sentence and figuring out what a pronoun like “it” refers to when there are multiple potential antecedents. A language model that scores highly on GLUE, therefore, can handle diverse reading comprehension tasks. Out of a full score of 100, the average person scores around 87 points. Baidu is now the first team to surpass 90 with its model, ERNIE.

BERT, by contrast, considers the context before and after a word all at once, making it bidirectional. It does this using a technique known as “masking.” In a given passage of text, BERT randomly hides 15% of the words and then tries to predict them from the remaining ones. This allows it to make more accurate predictions because it has twice as many cues to work from.

Darwin is operated through a Wi-Fi-enabled tablet that resembles an iPad and displays metrics on conditions across the home. Properties with the system are constructed with air quality sensors and filters that detect and remove impurities like pollution and smoke. They also have water purifiers that get rid of chlorine, heavy metals and other particles from tap water.

“We’re indoors for most of our lives, and while we may not be able to change that, Darwin gives you the ability to change your environment,” he said.

Not many are equipped with such high-tech systems as Darwin, but these communities offer wellness in other ways: growing produce for residents, for example, or providing outdoor space and fitness classes.

Evidence from a new study shows that memory circuits assist the mind in recalling thoughts by associating them with sensations. The mind can use the brain’s storage mechanisms to sort more important or urgent memories for faster recall. 

In particular, it remains unknown whether factors that structure the retrieval of external stimuli also apply to thought recall, and whether some thought features affect their accessibility in memory.

These observations appear to support the view that the conscious self uses memory as a tool. The mind uses the brain; it is not a passive illusion conjured up by the brain. The brain is active and ready, storing each sensation as we walk through daily life, but thoughts that involve planning are more readily recalled. It’s as if the self tells the brain, “Remember this,” and the brain obliges like a computer operator or librarian, pigeonholing the data where it can be recalled more easily later.

Deciphering how the brain processes sight and hearing could have implications for how we understand and treat conditions such as dyslexia, autism and schizophrenia.

Through a project called SENSOCOM, she is exploring how sensory perception affects communication, focusing on the brain’s deep subcortical structures.By doing this, she and her team are exploring a part of the brain traditionally excluded by research trying to understand communication impairments found in autism spectrum disorder and dyslexia, conditions which affect around 53 million people in Europe.

Home is the safest place to be while a pandemic rages outside. Health officials have said as much for weeks now.

Self-isolation forces victims of domestic violence and their children into uncomfortable and dangerous circumstances: Riding out the Covid-19 crisis, shut in with their abusers.

And the deluge of stress and fear -- of unemployment, of sickness, of death -- is only intensifying the abuse they face.

Kris Karnauskas, a professor of ocean sciences at the University of Colorado, has started walking around campus with a pocket-size carbon-dioxide detector. He’s not doing it to measure the amount of carbon pollution in the atmosphere. He’s interested in the amount of CO₂ in each room.

The indoor concentration of carbon dioxide concerns him—and not only for the usual reason. Karnauskas is worried that indoor CO₂ levels are getting so high that they are starting to impair human cognition.

Carbon dioxide, the same odorless and invisible gas that causes global warming, may be making us dumber.

As odds of a global recession rise, governments and central banks around the world are racing to fend off the economic damage from the spread of the coronavirus. The toll has already landed hard on jittery financial markets. Stocks continued to sell off on Thursday as the Dow Jones Industrial Average plunged 969 points, or about 3.6%, as investors fled stocks. Companies have shut factories, canceled conferences and drastically scaled back employee travel.

Meanwhile, the U.S. Senate on Thursday gave final passage to a roughly $8 billion spending package to provide medical supplies in hard-hit areas and pay for vaccine research. President Trump has said he will sign the bill. Despite such measures, many economists now say growth is likely to slow considerably this year — if not contract altogether.

Goldman Sachs projected on Sunday that because of the coronavirus, the U.S. economy would grow by an anemic 0.9% during the first three months of 2020 and would flatline during the second quarter.

Obama gives readers more than a mere recitation of events. He offers an insider’s peek into his thought process

Obama’s well-earned reputation as someone who could overthink almost anything is one reason fellow writers, especially in the media, found him so fascinating

Trump’s supporters found his “honesty” refreshing, by which they meant, he’s saying what I’m thinking, no matter how ignoble my thoughts.

If you've heard of the term "MSG," you might have also heard of its common -- but inaccurate -- connotations.For years, monosodium glutamate, a food additive known as MSG, has been branded as an unhealthy processed ingredient mainly found in Chinese food, despite a lack of supporting scientific evidence.

Now, activists have launched a campaign called "Redefine CRS." Headed by Japanese food and seasoning company Ajinomoto, the online campaign urges Merriam-Webster to change its entry to reflect the scientific consensus on MSG -- and the impact of misinformation on the American public's perception of Asian cuisine.

First off: what is MSG?Chances are, you've eaten it. It's a common amino acid naturally found in foods like tomatoes and cheese, which people then figured out how to extract and ferment -- a process similar to how we make yogurt and wine. This fermented MSG is now used to flavor lots of different foods like stews or chicken stock. It's so widely used because it taps into our fifth basic taste: umami (pronounced oo-maa-mee). Umami is less well known than the other tastes like saltiness or sweetness, but it's everywhere -- it's the complex, savory taste you find in mushrooms or Parmesan cheese.

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.

A few years ago, when my girls were in the second and third grades, they raved about the dance breaks they would occasionally have during the school day.

My kids' teachers were certainly not alone. More teachers are incorporating some form of movement into the school day, especially as the research is pretty clear: Physical activity in school leads to better cognitive performance and fewer behavioral issues, not to mention cutting down on stress and anxiety.

It all seems like a no-brainer, especially as research shows that childhood obesity seems to be getting worse. As former first lady Michelle Obama advocated, let's get our kids to move.The challenge, though, is persuading school administrations to consistently make time for physical activity when they are pressed to meet stringent academic requirements and find the money to pay for some of the training.

The response to the coronavirus pandemic has been unprecedented in terms of speed and scale. Commitments from governments and central banks to date are close to $7 trillion, according to an analysis by CNN Business. The total includes government spending, loan guarantees and tax breaks, as well as money printing by central banks to buy assets such as bonds and stock funds.

The figure includes the $2 trillion US relief package working its way through Congress and an anticipated 30 trillion yen ($274 billion) in stimulus from Japan that could be approved next month. In Europe, CNN Business tallied stimulus efforts by the biggest economies: Germany, France, the United Kingdom, Italy and Spain.

"The [$2 trillion US] stimulus package is likely the bare minimum needed to offset the current drag from the outbreak," Bank of America economist Joseph Song told clients Thursday. "The economy will likely need close $3 [trillion] in fiscal stimulus, if not more."

New research shows that people with depression use absolute words, such as “always,” “nothing,” or “completely,” more often than others.

Scientists have long tried to pin down the exact relationship between depression and language, and technology is helping us get closer to a full picture. Our new study, published in Clinical Psychological Science, has now unveiled a class of words that can help accurately predict whether someone is suffering from depression.

So far, personal essays and diary entries by depressed people have been useful, as has the work of well-known artists such as Cobain and Plath. For the spoken word, snippets of natural language of people with depression have also provided insight. Taken together, the findings from such research reveal clear and consistent differences in language between those with and without symptoms of depression.

Two MIT professors have found a strong relationship between students' grades and how much sleep they're getting. What time students go to bed and the consistency of their sleep habits also make a big difference. And no, getting a good night's sleep just before a big test is not good enough -- it takes several nights in a row of good sleep to make a difference.

100 students in an MIT engineering class were given Fitbits, the popular wrist-worn devices that track a person's activity 24/7, in exchange for the researchers' access to a semester's worth of their activity data

One of the surprises was that individuals who went to bed after some particular threshold time -- for these students, that tended to be 2 a.m., but it varied from one person to another -- tended to perform less well on their tests no matter how much total sleep they ended up getting.

Von Neumann, too, was deeply concerned about the inability of humanity to keep up with its own inventions. “What we are creating now,” he said to his wife Klári in 1945, “is a monster whose influence is going to change history, provided there is any history left.” Moving to the subject of future computing machines he became even more agitated, foreseeing disaster if “people” could not “keep pace with what they create.”

Oppenheimer, Einstein, von Neumann and other Institute faculty channeled much of their effort toward what AI researchers today call the “alignment” problem: how to make sure our discoveries serve us instead of destroying us. Their approaches to this increasingly pressing problem remain instructive.

Von Neumann focused on applying the powers of mathematical logic, taking insights from games of strategy and applying them to economics and war planning. Today, descendants of his “game theory” running on von Neumann computing architecture are applied not only to our nuclear strategy, but also many parts of our political, economic and social lives. This is one approach to alignment: humanity survives technology through more technology, and it is the researcher’s role to maximize progress.

After Jason Moore, from Portland, Oregon, saw headlines from national news sources on Google News about the Buffalo shooting at a local supermarket on Saturday afternoon, he did a quick search for the incident on Wikipedia. When no results appeared, he drafted a single sentence: "On May 14, 2022, 10 people were killed in a mass shooting in Buffalo, New York." He hit save and published the entry on Wikipedia in less than a minute.
