For the next couple of weeks, enjoy savings on Mynt’s heated foot massager, which I featured in my rad and random feet things article a while ago. It has 22 massage heads that push into pressure points on your feet, plus rollers on the bottom and air pressure help blood flow and alleviate aches.

If you’re a regular runner or cyclist, you might be used to tracking your journeys with your phone or wearable. But runs and rides are just the start when it comes to stuff you can log with your smartphone. You’ll find it’s possible to build a picture of your music listening history over many years, or keep track of all the cities you’ve visited in a particular year—all you need are the right apps....

From Rome’s vast Trajan’s Forum to Angkor Wat’s stone temples, cities have been magnets for trade, art, and culture since ancient times. Urban living as we know it first emerged around 3500 B.C.E. along the Nile Valley and Sumerian coast. Unlike the semipermanent villages that came before them, these social and political hubs were built around sophisticated systems of agriculture and transportation. Today, around 56 percent of the world’s population is urban, and by 2050 that number could jump to around 70 percent, by some estimates....

All of these fancy features came at a price, though, to the tune of around $300 each. Now, hold on to your hat, because you can still find the ST1, but at an alarming price reduction of $280. Yes, our good friends at BG Micro are selling the Seagate 5GB ST1 drive (Model ST650211CF) for $13.50. While that’s a pretty good price for a 5GB Compact Flash card, think of all the extra benefits that you get with a vintage ST1 versus a typical CF card: you could take it apart and expose the real platters and heads or replace a 2....

A group of astronomers aims to shake that assumption of stability with the Vanishing and Appearing Sources during a Century of Observations (VASCO) Project, by comparing 70-year-old surveys with recent images of the night sky to see what might have gone missing. After years of painstaking work, they recently announced their first results in the Astronomical Journal: at least 100 pinpricks of light that appeared in mid-20th century skies may have gone dark today....

First designed in 2006, the new version of the device is a more sophisticated and complicated design that can cloak a wider variety of waves. To create the new device, the researchers developed a new set of mathematical algorithms which, in turn, are used to engineer artificially structured “metamaterials” that have properties not found in natural materials. The metamaterials are what form the cloaking structures, which bend electromagnetic waves, like light, around an object, so it appears the object is no longer there....

On December 8, days of speculation over whether or not the Atlantic would see Tropical Storm Owen ended when the storm system moved towards colder waters that would keep it from strengthening. It previously had a 40 percent chance of developing into a tropical storm and would have been the first December tropical system in nine years. While the tropics have calmed down, the impacts from the 2022 season will be felt long after the new year begins....

Due to its high cost, energy intensiveness and overall ecological footprint, most environmental advocates view desalinization (or desalination) — the conversion of salty ocean water into fresh water — as a last resort for providing fresh water to needy populations. Sourcing fresh water from streams, rivers, lakes and underground aquifers and adhering to strict water conservation measures are much more viable for both economic and environmental reasons in most situations, although some desert regions with thirsty and growing populations may not have many such options....

It’s one of the few times that people can find the fun in statistics, which is why Lawrence Livermore National Laboratory asked one of their resident statisticians, Kristin Lennox, to decode the “math behind the mania” in the short and sweet video above. In the video, Lennox points out that while the sheer number of tickets being sold makes it incredibly likely that someone will win tonight’s jackpot, the chances of an individual person winning the jackpot are really slim....

The full force of the typhoon’s 180 MPH winds hit around 12:00 PM EDT on Wednesday. The islands likely suffered significant damage from the storm, and communications with the outside world will be sparse until crews from Guam can arrive and assess the extent of the damage. The Commonwealth of the Northern Marianas Islands (CNMI) became a territory of the United States in the years after World War II. Like residents of Puerto Rico, Guam, and the U....

Correction (August 8, 2022): The article initially said that iRobot was founded in 2012. The correct year is 2002.

But if Bezos and his team continue to flesh out Echo’s functionality in ways like adding in support for popular applications like Spotify, it could lead to a greater voice experience for all.

These odd creatures have flat foreheads that look like the bottom of a shoe. But it’s this strange suction-cup forehead that allows remora fish to cling onto dolphins even as they twirl into the air and slam back down into the water. In fact, scientists have long wondered whether the remora’s ribbed head held the secrets to better adhesives. Recently, this feature has become the intrigue of a group of international engineers from Beihang University, Imperial College London, and Swiss Federal Laboratories for Materials Science and Technology, who have sought to fabricate a version of this sucker structure to help drones get a better grip....

A paper published this week in Current Biology focuses on four paleofecal samples from the Bronze Age, Iron Age, and Baroque Age. While the researchers from the Institute for Mummy Studies, the University of Trento, and the Vienna Museum of Natural History were able to learn what kind of beer and cheese these people consumed, the findings more importantly show that industrialization likely transformed the Western diet, and that archaeology and gut health, like beer and blue cheese, make an oddly perfect pair....

The confirmation came from the Laser Interferometer Gravitational-Wave Observatory (LIGO), based in Louisiana and Washington State. The signal announced today came from the collision of two black holes. As Popular Science‘s Sophie Bushwick explains, the two black holes twirled around one another as they approached each other. The closer they got, the faster they spun, until they finally merged together into one giant black hole. The violent union released gravitational waves that LIGO detected as a “chirp” signal....

The report claims, the virtual reality headset was going to be more powerful than anything else on the market at the time, but all that processing firepower required a dedicated hub to house all the hardware. The headset would connect wirelessly to the hub and would only encompass the displays and the electronics it needed to sense movement and show content. Ive reportedly found the need for an extra machine unacceptable....

Apple typically saves its premiere announcements like new iPhones for later in the year, using its World Wide Developers Conference to offer a look at what’s coming to the devices many people already own. Usually that’s in the form of MacOS and iOS updates, though last year we also met Apple’s HomePod smart speaker and a 10.5-inch iPad Pro. In advance of the 2018 conference, here’s a look back at what we saw last year and what we expect for Monday’s events....

According to the Association of American Publishers, paperback sales country-wide increased by 2.7 percent from 2018 to 2019, while e-books declined by about 4.2 percent. That said, there’s no denying that being able to store hundreds of books on a single device is exceedingly convenient. However, it doesn’t necessarily mean that e-books on a dedicated reading device are more eco-friendly than owning stacks of classic paper books. If you’re deciding whether or not you should make the switch, here are some factors to consider....
