For decades, scientists working to predict changes in the climate relied mostly on calculations involving simple laws of physics and chemistry but little data from the real world. But with temperatures world-wide continuing to rise—and with data-collection techniques and technologies continuing to advance—scientists now rely on meticulous measurements of temperatures, ocean currents, soil moisture, air quality, cloud cover and hundreds of other phenomena on Earth and in its atmosphere.

“Now we can truly do climate studies because now we have observations to precisely say how weather trends have changed and are changing,

“When you are trying to develop long-term environmental records, including climate records, consistent measurement is incredibly valuable,” says Kevin Murphy, who as NASA’s chief science data officer oversees an archive of Earth observation data used by 3.9 million people last year. “It’s irreplaceable data.”

we are less like data processing machines and more like soft-bodied mollusks, picking up cues from within and without and transforming ourselves accordingly.

Still, we “insist that the brain is the sole locus of thinking, a cordoned-off space where cognition happens, much as the workings of my laptop are sealed inside its aluminum case,”

We get constant messages about what’s going on inside our bodies, sensations we can either attend to or ignore. And we belong to tribes that cosset and guide us

GPT-4, in contrast, is a state-of-the-art system capable of creating not just words but describing images in response to a person’s simple written commands.

When shown a photo of a boxing glove hanging over a wooden seesaw with a ball on one side, for instance, a person can ask what will happen if the glove drops, and GPT-4 will respond that it would hit the seesaw and cause the ball to fly up.

an AI program, known as a large language model, that early testers had claimed was remarkably advanced in its ability to reason and learn new things

During Mr. Obama’s first term, MSNBC underwent a metamorphosis from a CNN also-ran to the anti-Fox, and handily beat CNN in the ratings along the way. Now that it is known, at least to those who cannot get enough politics, as the nation’s liberal television network, the challenge in the next four years will be to capitalize on that identity.

MSNBC, a unit of NBCUniversal, has a long way to go to overtake the Fox News Channel, a unit of News Corporation: on most nights this year, Fox had two million more viewers than MSNBC. But the two channels, which skew toward an audience that is 55 or older, are on average separated by fewer than 300,000 viewers in the 25- to 54-year-old demographic that advertisers desire. On three nights in a row after the election last week, MSNBC — whose hosts reveled in Mr. Obama’s victory — had more viewers than Fox in that demographic.

MSNBC sees itself as the voice of Mr. Obama’s America.

Mr. Rubio was asked how old the earth is. After declaring “I’m not a scientist, man,” the senator went into desperate evasive action, ending with the declaration that “it’s one of the great mysteries.”

Reading Mr. Rubio’s interview is like driving through a deeply eroded canyon; all at once, you can clearly see what lies below the superficial landscape. Like striated rock beds that speak of deep time, his inability to acknowledge scientific evidence speaks of the anti-rational mind-set that has taken over his political party.

that question didn’t come out of the blue. As speaker of the Florida House of Representatives, Mr. Rubio provided powerful aid to creationists trying to water down science education. In one interview, he compared the teaching of evolution to Communist indoctrination tactics — although he graciously added that “I’m not equating the evolution people with Fidel Castro.

A 200-year-long drought 4,200 years ago may have killed off the ancient Sumerian language, one geologist says.

no written accounts explicitly mention drought as the reason for the Sumerian demise, the conclusions rely on indirect clues.

his was not a single summer or winter, this was 200 to 300 years of drought," said Matt Konfirst, a geologist at the Byrd Polar Research Center.

A team of researchers walked every street in 228 census tracts around Los Angeles and New Orleans and recorded every outdoor ad they saw. Another group surveyed 2,881 residents of the same census tracts by telephone, paying them to report their height, weight and other information. After analyzing this hard-won data, the authors conclude: “For every 10 percent increase in food advertisements, the odds of being obese increased by 5 percent.” That is, areas with more outdoor food ads have a higher proportion of obese people than ones with fewer ads.

The problem is that their policy recommendations rest on a crucial but unjustified assumption: that any link between obesity and advertising occurs because more advertising causes higher rates of obesity. But the study at hand showed only an association: people living in areas with more food ads were more likely to be obese than people living in areas with fewer food ads. To be fair, the researchers correctly note that additional steps would be needed to prove that food ads cause obesity. But until those steps are taken, talk of restricting ads is premature. In fact, it is easy to imagine how the causation could run the opposite way (something the article did not mention): If food vendors believe obese people are more likely than non-obese people to buy their products, they will place more ads in areas where obese people already live. Suppose we counted ads for fitness-oriented products like bicycles and bottled water, and found more of those ads in places with less obesity. Would it then be wise anti-obesity policy to subsidize such ads? Or would the smarter conclusion be that the fitness companies suspect that the obese are less likely than the fit to buy their products?

When we seek to base policy on evidence, we must remember that not all “evidence” is created equal. Taken at face value, the study on ads and obesity provides some indication that the two are linked, but no evidence that food ads cause obesity. The fact that the causal conclusion may coincide with a moral belief — that it is wrong to tempt people who overeat by showing them ads for food — does not make it valid.

As soon as you hit Google’s territorial waters, you came under our jurisdiction, our terms of service. Our laws–or lack thereof–apply here. By boarding our self-driving boat you granted us the right to all feedback you provide during your journey. This includes the chemical composition of your sweat.

Unified logins let us get to know our audience in ways we never could before. They gave us their locations so that we might better tell them if it was raining outside. They told us where they lived and where they wanted to go so that we could deliver a more immersive map that better anticipated what they wanted to do–it let us very literally tell people what they should do today. As people began to see how very useful Google Now was, they began to give us even more information. They told us to dig through their e-mail for their boarding passes–Imagine if you had to find it on your own!–they finally gave us permission to track and store their search and web history so that we could give them better and better Cards. And then there is the imaging. They gave us tens of thousands of pictures of themselves so that we could pick the best ones–yes we appealed to their vanity to do this: We’ll make you look better and assure you present a smiling, wrinkle-free face to the world–but it allowed us to also stitch together three-dimensional representations. Hangout chats let us know who everybody’s friends were, and what they had to say to them. Verbal searches gave us our users’ voices. These were intermediary steps. But it let us know where people were at all times, what they thought, what they said, and of course how they looked. Sure, Google Now could tell you what to do.

“We learned so much about regulation with Google Health. It turns out, the government has rules about health records, and that people care about these rules for some reason. So we began looking around for ways to avoid regulation. For example, government regulation meant it was much easier to experiment with white space in Kenya than in the United States. So we started thinking: What if the entire world looked more like Kenya? Or, even better, Somalia? Places where there are no laws. We haven’t adapted mechanisms to deal with some of our old institutions like the law. We aren’t keeping up with the rate of change we caused through technology. If you look at the laws we have, they’re very old. A law can’t be right if it’s 50 years old. Like, it’s before the Internet

If you already live in the heartland, the message is to stay. If you come from the heartland and have left, the message is to return. But what if you’re one of the tens of millions of people who can’t stay in or go home to the heartland because your home — your roots — are in the BosWash corridor of the Northeast or the urbanized areas of the West Coast? …

is this even possible in a place where paying my mortgage and other bills requires that my wife and I — like my equally striving neighbors — devote ourselves to high-stress work during nearly every waking hour of our days? If I were independently wealthy, perhaps the good life that Dreher describes would be a possibility in the Philadelphia suburbs. But alas…

There are trade-offs in all things, and no perfect solution, geographical or otherwise. Thing is, life is short, and choices have to be made. It’s not that people living in these workaholic suburbs are bad, not at all; it’s that the culture they (we) live in defines the Good in such a way that choosing to “do the right thing” ends up hollowing out your life, leaving you vulnerable in ways you may not see until tragedy strikes.

“The word ‘date’ should almost be stricken from the dictionary,” Ms. Silver said. “Dating culture has evolved to a cycle of text messages, each one requiring the code-breaking skills of a cold war spy to interpret.”

Raised in the age of so-called “hookup culture,” millennials — who are reaching an age where they are starting to think about settling down — are subverting the rules of courtship.

Instead of dinner-and-a-movie, which seems as obsolete as a rotary phone, they rendezvous over phone texts, Facebook posts, instant messages and other “non-dates” that are leaving a generation confused about how to land a boyfriend or girlfriend.

They are uniquely adapted to this job – because they can see underwater. And it turns out that with a little practice, their unique vision might be accessible to any young person.

Gislen figured that in order for the Moken children to see clearly underwater, they must have either picked up some adaption that fundamentally changed the way their eyes worked, or they had learned to use their eyes differently under water.

There are two ways in which you can theoretically improve your vision underwater. You can change the shape of the lens – which is called accommodation – or you can make the pupil smaller, thereby increasing the depth of field.

There is no mystery about Barack Obama’s greatest presidential achievement: He stopped the Great Recession from becoming the second Great Depression. True, he had plenty of help, including from his predecessor, George W. Bush, and from the top officials at the Treasury Department and Federal Reserve. But if Obama had made one wrong step, what was a crushing economic slump could have become something much worse.

It is Obama’s unfortunate fate that the high-water mark of his presidency occurred in the first months, when the world flirted with financial calamity. The prospect of another Great Depression — a long period of worsening economic decline — was not far-fetched.

In the first quarter of 2009, as Obama was moving into the White House, monthly job losses averaged 772,000. The ultimate decline in employment was 8.7 million jobs, or 6.3 percent. Housing prices and stock values were collapsing. From their peak in February 2007 to their low point, housing prices dropped 26 percent. Millions of homeowners were “underwater” — their houses were worth less than the mortgages on them. Stock prices fell roughly by half from August 2007 to March 2009.

Many observers saw quite quickly that Trump’s personality was highly disordered.

The opportunity for everyone to learn a lot about this domineering, exploitative, unstable and superficially charismatic personality type has presented itself on a grand scale.

All the neuroimaging, all the psychological theorising, all the psychiatric experimentation with pharmacology, it’s already prompting a huge need for careful, scientifically anchored engagement with the ethical and philosophical debate about what it is to be human.

It also recognized a potentially life-threatening aspect of campus culture: Penn Face. An apothegm long used by students to describe the practice of acting happy and self-assured even when sad or stressed, Penn Face is so widely employed that it has showed up in skits performed during freshman orientation.

While the appellation is unique to Penn, the behavior is not. In 2003, Duke jolted academe with a report describing how its female students felt pressure to be “effortlessly perfect”: smart, accomplished, fit, beautiful and popular, all without visible effort. At Stanford, it’s called the Duck Syndrome. A duck appears to glide calmly across the water, while beneath the surface it frantically, relentlessly paddles.

Citing a “perception that one has to be perfect in every academic, cocurricular and social endeavor,” the task force report described how students feel enormous pressure that “can manifest as demoralization, alienation or conditions like anxiety or depression.”

On Wednesday, the scientists at NASA kind of freaked out. They announced the discovery of some seemingly Earth-like planets outside of our solar system, a group of rocky globes they're calling 'TRAPPIST-1.'

To be completely blunt, the most exiting thing for actual scientists is that these planets are close enough that we're actually going to be able to study them – particularly when the James Webb Space Telescope launches (October 2018.) When that launches, it will have a real shot at actually taking a look at the atmospheres of these planets – or if they have atmospheres at all. So it's like a promise of future excitement

The closer the system is to our solar system – the more the star is like the Sun and the planet is like the Earth, the more likely we are to understand what we're looking at. That's what makes it exciting.

Our solar system is spread out by comparison. This cramped little system finds each planet’s orbit closer to their star, TRAPPIST-1, than Mercury is to ours. Of all the planets discovered, TRAPPIST-1f is the most likely to sustain life, NASA scientists say. Those closer planets may be too hot to contain liquid water, while those beyond may be too cold.

Another interesting consideration, this star, since it burns so slowly, will likely outlive ours by a trillion years. So if the Earth is vanquished and the situation is right, we may find a new Eden on TRAPPIST-1f.

SAN FELIPE, Mexico — In the shallow sea waters of the Gulf of California swims a porpoise that few have seen, its numbers dwindling so fast that its very existence is now in peril.

“If you can’t remove the threats, the population keeps declining,” Dr. Turvey said. “You don’t have time for complacency.”

More subtly, there are many who insist that consciousness just reduces to brain states - a pang of regret, say, is just a surge of chemicals across a synapse. They are collapsers rather than deniers. Though not avowedly eliminative, this kind of view is tacitly a rejection of the very existence of consciousness

it occurred to me that the problem might lie not in nature but in ourselves: we just don't have the faculties of comprehension that would enable us to remove the sense of mystery. Ontologically, matter and consciousness are woven intelligibly together but epistemologically we are precluded from seeing how. I used Noam Chomsky's notion of "mysteries of nature" to describe the situation as I saw it. Soon, I was being labelled (by Owen Flanagan) a "mysterian"

Dualism makes the mind too separate, thereby precluding intelligible interaction and dependence.
