This New Pyramid-Like Shape Always Lands With the Same Side Up

The original version of this story appeared in Quanta Magazine. In 360 BC, Plato envisioned the cosmos as an arrangement of five geometric shapes: flat-sided solids called polyhedra. These immediately became important objects of mathematical study. So it might be surprising that, millennia later, mysteries still surround even the simplest shape in Plato’s polyhedral universe: the tetrahedron, which has just four triangular faces. One major open problem, for instance, asks how densely you can p

A Special Diamond Is the Key to a Fully Open Source Quantum Sensor

Quantum computing is either a distant dream or an imminent reality depending on whom you ask. And while much of this year's Quantum Village at the Defcon security conference in Las Vegas is focused on emerging research and threat analysis, Village cofounders Victoria Kumaran and Mark Carney are also working to make a currently available quantum technology more accessible to hackers and anyone else. In a main-stage Defcon talk on Saturday, the pair will present an open source and affordable quan

I can never go back to a phone without this display feature

Tushar Mehta / Android Authority I have never been the kind to rise and shine. For the 31 years of my existence — or, at least, for the major chunk I remember vividly, waking up early in the morning has been a woeful exercise for me, unless, of course, it is for traveling or hosting people I love. Instead, I can feel the neurons in my brain firing up better in the dead of the night, and so, I have made the effort to ensure the tech in my life is best suited to make better use of those hours.

Long-term exposure to outdoor air pollution linked to increased risk of dementia

Dementias such as Alzheimer's disease are estimated to affect more than 57.4 million people worldwide, a number that is expected to almost triple to 152.8 million cases by 2050. The impacts on the individuals, families and caregivers and society at large are immense. While there are some indications that the prevalence of dementia is decreasing in Europe and North America, suggesting that it may be possible to reduce the risk of the disease at a population level, elsewhere the picture is less p

This epic Severance mural might be the coolest thing you see all week

LA is populated with marketing materials for all sorts of entertainment, but this giant painted Severance mural is one-of-a-kind. Apple shared photos of “The Exalted Victory of Cold Harbor” mural on display near an Apple TV+ billboard on Melrose Avenue in Los Angeles this week. The finishing touches were put on the mural at the end of July, according to passersby on social media. These are the shots shared by Apple, including a selfie by Severance lead actor Adam Scott: Meanwhile, a Facebook

For giant carnivorous dinosaurs, big size didn’t mean a big bite

When a Spinosaurus attacked a T. rex in Jurassic Park III, both giant carnivores tried to finish the fight with one powerful bite of their bone-crushing jaws. The Spinosaurus won, because when the movie was being made back in the early 2000s, fossil discoveries suggested it was the largest carnivorous dinosaur that ever lived. But new research provides evidence that size and weight didn’t always create a powerful bite. “The Spinosaurus and the T. rex didn’t live at the same time at the same con

Texas politicians warn Smithsonian it must not lobby to retain its space shuttle

Texas lawmakers, seemingly not content with getting NASA's endorsement to move a retired space shuttle to Houston, are now calling for an investigation into how the Smithsonian allegedly objected to relocating the orbiter it has owned for more than a decade. Senator John Cornyn and Representative Randy Weber on Thursday sent a letter to John Roberts, the Smithsonian Institution's chancellor and chief justice of the United States, suggesting that the Smithsonian's staff may have violated the law

James Gunn Doesn’t Want You to Trust Anything About ‘The Batman Part II’ Until It Comes From Him

The Hollywood rumor mill is nothing new, especially when it comes to high-profile projects, but social media can encourage speculation to spiral out of control. While DC’s James Gunn is no stranger to chaos, one recent rumor prompted him to take to social media to warn against believing things that don’t come through verified channels—a position Gunn can take, being the rare studio head who’s terminally online enough to nip disinformation in the bud. Gunn put his foot down regarding the specula

Review: The Sandman S2 is a classic tragedy, beautifully told

I unequivocally loved the first season of The Sandman, the Netflix adaptation of Neil Gaiman's influential graphic novel series (of which I am longtime fan). I thought it captured the surreal, dream-like feel and tone of its source material, striking a perfect balance between the anthology approach of the graphic novels and grounding the narrative by focusing on the arc of its central figure: Morpheus, lord of the Dreaming. It's been a long wait for the second and final season, but S2 retains al

New Gel Could Heal Stubborn Diabetic Wounds in Under 2 Weeks

For people with diabetes, high blood sugar can damage blood vessels and nerves, leading to chronic wounds that stay open for months. But a new gel-based treatment could massively speed up the healing process for people with diabetes, allowing wounds to close in just days, according to a new study. The new treatment targets thrombospondin-1 (TSP-1), a protein that inhibits the growth of new blood vessels, a crucial step in the healing process. Targeting this protein increased new blood vessel fo

It Looks Like a School Bathroom Smoke Detector. A Teen Hacker Showed It Could Be an Audio Bug

A couple of years ago, a curious, then-16-year-old hacker named Reynaldo Vasquez-Garcia was on his laptop at his Portland-area high school, seeing what computer systems he could connect to via the Wi-Fi—“using the school network as a lab,” as he puts it—when he spotted a handful of mysterious devices with the identifier “IPVideo Corporation.” After a closer look and some googling, Garcia figured out that a company by that name was a subsidiary of Motorola, and the devices he’d found in his scho

Solar-Powered Device Turns Moon Dirt Into Bricks, a Potential Breakthrough in Lunar Construction

Both the U.S. and China have set their sights on the Moon, aiming to break ground on permanent lunar bases within the next decade. Though there’s no legal basis for claiming territory in space, whichever country gets there first will gain a coveted first-mover advantage, allowing it to set certain ground rules about who can do what, where. But getting there first is only half the battle. Actually establishing a sustained lunar presence presents significant logistical and engineering challenges.
