The problem Greene and Lobb worked on predicts, basically, that every such path contains sets of four points that form the vertices of rectangles of any desired proportion.But again, the problem Greene and Lobb solved involves curves that are smooth, and therefore continuous.

Unlike CHIME, which looks at small chunks of the sky at any given time, Caltech’s Survey for Transient Astronomical Radio Emission 2 (STARE2) telescope observes the entire sky at once, which allowed the Caltech team to quickly confirm that the burst was extremely powerful.

Here’s how in-person voting should look during the coronavirus pandemic: lots of polling places, fully staffed with well-protected election workers, each serving small numbers of voters who are able to quickly get in and out without having to congregate at length in close quarters.

For natural materials, breaking down isn't an issue, as microbes have evolved ways of digesting them to obtain energy or useful chemicals.The microbes that currently digest PET break down that ring as well, making them unsuitable for recycling.

Children who are now in booster seats, all around the world, are going to be inventing solutions to the crisis, and they'll need support, investment, and, yes, well-designed capitalism to get them off the ground.

Sick patients need their vitals recorded and their symptoms monitored, and staff needs to get updates if someone’s condition starts to worsen (from fever and cough to shortness of breath as blood oxygen levels fall).

The worse news is that said data has since been discovered in an online hacking forum, as first reported by ZDNet. The haul includes names, addresses, phone numbers, emails, and dates of birth, and celebrities, politicians, and journalists are among those affected.

As millions of Chinese remain in lockdown to prevent the spread of coronavirus, a new global problem has arisen: a shortage of surgical masks.And that isn't just a problem for China: The US gets 95 percent of its surgical masks from overseas, and China is the world's largest supplier.

It's counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process and less time before takeoff, according to a new paper in Physical Review E.

Google researchers made headlines early this month for a study that claimed their artificial intelligence system could outperform human experts at finding breast cancers on mammograms.Machine-enabled healthcare may bring us many benefits in the years to come, but those will be contingent on the ways in which it’s used.

Long before climate change became recognized as one of the world’s major problems, water scarcity was widely recognized as a challenge for humanity.Unfortunately, the rise of awareness about the challenges of climate change had a perverse result when it came to the world working collectively to reduce global water scarcity.

Earlier this year one of the top mathematicians in the world dared to confront the problem—and came away with one of the most significant results on the Collatz conjecture in decades.On September 8, Terence Tao posted a proof showing that—at the very least—the Collatz conjecture is “almost” true for “almost” all numbers.

The p refers to the p-value, a ridiculously complicated statistical entity that’s essentially a measure of how surprising the results of a study would be if the effect you’re looking for wasn’t there.

“We wanted to understand how easy it is for someone to be able to penetrate the device without the user downloading an application,” says Kryptowire CEO Angelos Stavrou.

Android users are groaning and websites are moaning, but first: a cartoon about what to do with a broken laptop .Here's the news you need to know, in two minutes or less.146 new vulnerabilities all come preinstalled on Android phones.

These neo-banks have been trying to make money in the usual ways: By taking a cut of credit or debit card transactions, collecting interest on consumer deposits, and making loans.

In 2017, after the company said it was closing in on the milestone, IBM researchers published results that appeared to move the goalposts.Soon, researchers from Chinese ecommerce company Alibaba, which has its own quantum computing program, released analysis claiming that the device could not do what Google said.
