Officially called Title 42 of the U.S. Code, the little-known law was established initially in 1944 to prevent the spread of influenza and allow authorities to bar entry to foreigners deemed to be at risk of spreading the disease. Donald Trump invoked the law in 2020. It’s set to expire at the end of the year.

In 2022, water levels in some of the world’s largest rivers, including the Rhine in Europe and the Yangtze in China, fell to historically low levels. The Mississippi River fell so low in Memphis, Tennessee, in mid-October that barges were unable to float, requiring dredging and special water releases from upstream reservoirs to keep channels navigable. Earth scientists see this year’s dramatic plunge in water levels as a preview of a climate-altered future.

The cost of a fusion power plant needs to go well below the US$3.5 billion of the National Ignition Facility. These steps will require significant investment from both the federal government and private industry.

U.S. consumers waste a lot of food year-round – about one-third of all purchased food. That’s equivalent to 1,250 calories per person per day, or US$1,500 worth of groceries for a four-person household each year, an estimate that doesn’t include recent food price inflation.

We are used to thinking that going digital means going green. But driving a small car to the movie theatre with a friend may have lower carbon emissions than streaming the same movie alone at home.

Young people’s estimated 27% turnout rate in 2022 marks a near-record for an age group that has historically participated at lower rates in midterm elections. Whether this is a long-term trend or not will depend on whether communities and political groups implement the changes that research suggests can lead to sustained increases in youth voter turnout.

Divided government – including during the upcoming legislative session – will not produce greatly different legislative results than unified government, because unified government isn’t very productive in the first place: It’s really hard to get things done even when the same party controls both chambers and the presidency.

Every time you flush a toilet, it releases plumes of tiny water droplets into the air around you. These droplets, called aerosol plumes, can spread pathogens from human waste and expose people in public restrooms to contagious diseases. Here’s the visual proof.

There has been much excitement at the discovery of a treasure trove of notes from the lectures of the great German idealist philosopher G.W.F. Hegel. Before rejoicing we should ask: why does Hegel have this tricky reputation? And is it reasonable to expect that this new set of lecture notes will finally shed light on what can seem so obscure about his thinking?

Pit bulls have been in the news in South Africa after a series of deadly attacks on humans by the dogs. There have been revenge attacks on the dogs and politicians have called for their ban – tapping into a history of dogs being used by their white owners to intimidate and attack black South Africans. A racist incident then made the news when a dog lover responded with fury to the call for a ban.

The results of an experimental drug paint a mixed picture for those with Alzheimer’s. On one hand, this is the first drug that has been shown to have any effect on slowing the progression of the disease. On the other hand, the apparent effects are slight and the risks are not inconsiderable.

The rosy employment figures come despite repeated efforts by the Federal Reserve to tame the job market and the wider economy in general in its fight against the worst inflation in decades. Meanwhile, there aren’t enough people to fill the jobs being advertised.

Far-right extremists or other hate groups can claim they are just venting or even fantasizing – both of which would be protected under the First Amendment. In the absence of any specific plan, threat or incitement, group members may never suffer legal consequences for oral or written expressions that nonetheless create fear in those who draw these groups’ ire.

Since 1900, in states across the country, lethal injections have been more frequently botched than any of the other type of execution methods used throughout that period. This includes hanging, electrocution, the gas chamber and the firing squad – even though these approaches are not without their problems.

On November 15, a baby girl in Manila became the eight billionth person in the world. Of those 8 billion people, 60% live in a town or city. By the end of the 21st century, cities will account for 85% of Earth’s predicted 10 billion inhabitants.

Retailers are gearing up for another blockbuster holiday shopping season, but consumers burned by the highest inflation in a generation may have other ideas. Amazon said it is laying off 10,000 workers, one of several big companies announcing job cuts recently. Bezos even cautioned consumers to hold off on big purchases like cars, televisions and appliances to save in case of a recession in 2023.

The Passenger is a book of life and liveliness. The novel’s language communicates energy, not entropy – a sense of opening up, not winding down. At its most localised, this verbal exuberance runs through individual lexical choices. There seems no word that McCarthy doesn’t know and he fans life into archaic or obscure terminology (eskers, kedge, lemniscate, uncottered and many more).

Controversy has dogged the event ever since sport’s governing body, FIFA, handed Qatar hosting duties back in 2010. In spite of the controversy, the World Cup will be the most-watched sporting event of the year. Here are quick guide of the good and bad.

Twitter’s dual role in fostering real-time communication and acting as an arbitrator of authoritative information is of crucial interest to academics, journalists and government agencies. If Twitter were to collapse, there’s no clear replacement in sight.

To return the French language to its rightful place as the voice of human rights, the Québec government must promote it as a tool of a human rights-based civic education, not a mandatory language. Welcoming immigrants would subsequently not be an obstacle to the French language or francophone culture — it would be a benefit.

Arrests have actually been going down each year since 2010 as more states legalize medical or recreational use of the drug. In 2019, for example, more than 500,000 marijuana possession arrests were reported, so the 2020 arrest numbers represent a single-year decline of 36%.

Of NASA’s 135 Space Shuttle missions, only about 40% launched on time. While Artemis 1 is continuing the long tradition of delayed NASA launches, there are good reasons for the high level of caution that underlies these delays.

The failure of the expected GOP “red wave” might mark a passing of the high watermark for the political fortunes of Donald Trump. Or, to put it another way, America may have passed peak Trump after he took a big share of the blame for the failure of the Republican Party to capitalise on the highest inflation figures in 40 years, America’s rising murder rate, and what Republicans’ perceive as Joe Biden’s underperformance as president.

Like Twitter, Mastodon allows users to post, follow people and organizations, and like and repost others’ posts. But while Mastodon supports many of the same social networking features as Twitter, it is not a single platform. Instead, it’s a federation of independently operated, interconnected servers.

First it was the “Great Resignation.” Then it was “nobody wants to work anymore.” Now it’s “quiet quitting.” Yet it seems like no one wants to talk about what I see as the root cause of America’s economic malaise. The inability to dictate and meaningfully control one’s own working life is the problem.

Numbers Republican candidates and politicians keep referring to as representing an “invasion” of migrants represent encounters, not the number of individuals who have come across the border. It’s a misleading and inaccurate way of describing the number of people coming into the U.S.

Drug overdose deaths from opioids continue to rise in the U.S. as a result of both the misuse of prescription opioids and the illicit drug market. But an interesting trend has developed: Opioid emergency room visits drop by nearly 8% and opioid prescriptions are modestly lower in states where marijuana is legalized.

A warning about the threat of political violence heading into the 2022 midterm elections was issued to state and local law enforcement officials by the U.S. Department of Homeland Security on Oct. 28.

The U.S. military learned a valuable lesson about race during the Vietnam War: Diversity does not happen without affirmative action. The conservative majority of the United States Supreme Court is about to unlearn that lesson.

The Supreme Court’s historically low public standing has prompted a national conversation about the court’s legitimacy. It’s even drawn rare public comment from three sitting Supreme Court justices. What’s referred to by experts as the problem of “judicial legitimacy” may seem abstract, but the court’s faltering public support is about more than popularity.

Is student debt cancellation unfair? It isn’t as simple as yes or no answer. It seems to violate the moral principle of following through on one’s promises. Fairness and respect, however, also demand that society address the magnitude of student debt today, and especially the burden it imposes on low-income, first-generation and Black borrowers.

Humans can best protect sea turtle hatchlings as they make their way from the beach to the sea if they know precisely when the baby turtles will appear. But predicting emergence has been difficult. By placing a simple sensor disguised as a turtle egg in the nest, it indicates when the baby turtles would emerge from the sand and swarm toward the water.
