A speech pathologist named Christina Hunger claims to have taught her dog Stella to communicate by stepping on buttons, each of which says a word like "walk", "park", or "eat". She says the dog can even form short phrases by pushing buttons in a certain order. She posted a video of Stella pushing "happy ball want outside" on her Instagram. Her cat probably pushes "hate dog hate vacuum outside inside outside inside want food hate dog" over and over again.
Hunger, who works in San Diego with 1- and 2-year-old children, many of whom also use
devices that help them communicate, began teaching Stella words when the canine was about 8 weeks old.

A new book celebrates the hand-drawn infographics made by W.E.B. Du Bois for the 1900 World's Fair in Paris. The charts and graphs illustrate black population, land ownership rates, income, and other demographic statistics in the period of Reconstruction following the Civil War. Don't confuse

A year ago, Voyager 2 officially left our solar system, crossing the heliopause — the area where the sun's influence ceases — and into interstellar space. Recently published data from that event show that this passage was quick compared to Voyager 1, which took a month to traverse the border region. Scientists are working to understand how this area can vary so much in size, and what its overall shape might be.
A lot of today's economy depends on GPS, and the system is more fragile and vulnerable to hacking than many people would like. Besides obvious things like navigation, everything from cell networks to banking to shipping to first responders rely on the accuracy of the satellite system. Other countries are developing their own networks, and alternative technologies are being tested.
But is it wise for the rest of the world to rely on their continued

New evidence suggests that the universe might be spherical. Much debate on the subject has focused on the amount of matter in the universe; a curved shape would mean that it's sufficiently massive to stop expanding at some point and begin contracting.

Some senators are proposing a bill they call the Filter Bubble Transparency Act (FBTA), which will regulate the way social media sites use consumer data to show users content like ads. The bill will also allow users to opt out of receiving targeted content. Critics of the bill say the terminology used is too vague and that the bill is too confusing to be effective.
As antibiotic-resistant bacteria become a serious problem, some people are looking to phages as a possible solution. Phages are a type of virus that attack bacteria, hijacking their metabolism to reproduce. Unlike antibiotics, they each target only one specific species of bacterium and may not have side effects. Studies are underway, but many questions remain before these treatments can enter widespread use.
of cocktails, some researchers say phages should be genetically engineered to bind to specific receptors and also to kill bacteria in novel ways.

This roundup of noteworthy new science books includes a review of
Lightspeed, the history of efforts to measure the speed of light. Since the speed of light — which is constant, and which cannot be exceeded — is central to physics, it's an important story.
Vignette refers to a short description, like the reviews in this list of books. It also means an image with faded edges; there's a

Despite its appealing

"OK, boomer" has fast become the ultimate put-down for young people to deploy against their elders, including members of Generation X who aren't boomers at all. To illustrate its effectiveness, many older commentators have expressed outrage at the phrase, an age-specific "whatever" well-suited to a time when young people are mobilizing to solve problems that their parents have not been willing or able to address.
