Collective False Memories: What’s Behind the ‘Mandela Effect’?

Would you trust a memory that felt as real as all your other memories, and if other people confirmed that they remembered it too? What if the memory turned out to be false? This scenario was named the ‘Mandela effect’ by the self-described ‘paranormal consultant’ Fiona Broome after she discovered that other people shared her (false) memory of the South African civil rights leader Nelson Mandela dying in prison in the 1980s.

Is a shared false memory really due to a so-called ‘glitch in the matrix’, or is there some other explanation for what’s happening? Broome attributes the disparity to the many-worlds or ‘multiverse’ interpretation of quantum mechanics. Read More

Metagenomic Sleuthing Treats Illness Like a Crime Scene

Pathogens move fast.

You wake up one morning feeling ready to take on the world. On your way to work, you notice your throat’s a bit scratchy, your forehead a bit warm. By lunch you’ve got a pounding headache and it hurts to breathe. Co-workers agree, you’ve got whatever’s been going around. You end the day early, using the last of your strength to drag yourself to bed. Read More

When Earth Became a ‘Mote of Dust’

We glimpsed Earth’s curvature in 1946, via a repurposed German V-2 rocket that flew 65 miles above the surface. Year-by-year, we climbed a little higher, engineering a means to comprehend the magnitude of our home.

In 1968, Apollo 8 lunar module pilot William Anders captured the iconic Earthrise photo. We contemplated the beauty of our home. Read More

Has Dogma Derailed the Search for Dark Matter?

According to mainstream researchers, the vast majority of the matter in the Universe is invisible: it consists of dark-matter particles that do not interact with radiation and cannot be seen through any telescope. The case for dark matter is regarded as so overwhelming that its existence is often reported as fact. Lately, though, cracks of doubt have started to appear. In July, the LUX experiment in South Dakota came up empty in its search for dark particles – the latest failure in a planet-wide, decades-long effort to find them. Some cosmic surveys also suggest that dark particles cannot be there, which is especially confounding since astronomical observations were the original impetus for the dark-matter hypothesis.

Energy Observer: Around the World on Renewables

For over two decades, 45-year-old, French documentary maker Jerome Delafosse has been diving into oceans the world over to film marine life, and he’s thrilled about his next expedition—above water. This spring, he will serve as chief explorer aboard the Energy Observer, a boat powered by the sun, wind and hydrogen. In a first-of-its-kind endeavor, Delafosse and his team plan to circumnavigate the globe over six years, visiting 101 ports in 50 countries, while relying entirely on renewable energy sources to reach their destinations.

Delafosse and his compatriot, 37-year-old Victorien Erussard, who is the boat’s captain, hope to renew the legend of this 30-meter-long, 13-meter-wide catamaran, which was built in 1982 and named Formule Tag. It won the Trophéé Jules Vernes for the team Enza New Zealand skippered by Sir Peter Blake. Currently, it’s being equipped with its new energy systems in the northwestern French port of Saint Malo.

Who Isn’t Profiting Off the Backs of Researchers?

By Jon Tennant | February 1, 2017 12:33 pm

ResearchGate-gate isn’t quite as catchy as other scandals, but it is something we might be hearing more about in the future.

A recent article published by Sarah Bond at Forbes encouraged researchers to remove all of their articles from the for-profit company, Academia.edu. This has led to a wave of account deletions at the site, and also at ResearchGate, two sites dueling with each other to become the “Facebook for academics.”

The issue Bond raises is this: Why should companies generate profits from research with little transparency? It’s a good question.

This sounds suspiciously like the entire scholarly publishing ecosystem to me, and it is not clear why Academia.edu is in Bond’s crosshairs. For decades, for-profit companies have been making vast sums of money from researchers’ work, and often with profit margins in excess of 35 percent, greater than those even of Google (25 percent) Apple (29 percent) and even the largest oil companies like Rio Tinto (23 percent).

The Frog Tongue’s Sticky Secrets Revealed

How does one get stuck studying frog tongues? Our study into the sticky, slimy world of frogs all began with a humorous video of a real African bullfrog lunging at fake insects in a mobile game. This frog was clearly an expert at gaming; the speed and accuracy of its tongue could rival the thumbs of texting teenagers. Read More

You Might Be in a Medical Experiment and Not Even Know It

By Alice Dreger | January 31, 2017 12:34 pm

In the long view, modern history is the story of increasing rights of control over your body – for instance, in matters of reproduction, sex, where you live and whom you marry. Medical experimentation is supposed to be following the same historical trend – increasing rights of autonomy for those whose bodies are used for research.

Indeed, the Nuremberg Code, the founding document of modern medical research ethics developed after the Second World War in response to Nazi medical experiments, stated unequivocally that the voluntary, informed consent of the human subject is essential. Every research ethics code since then has incorporated this most fundamental principle. Exceptions to this rule are supposed to be truly exceptional. Read More

Archivists Want AI to Help Save, Analyze Everything Trump Says

A week hasn’t even passed since the inauguration, but television news is saturated with the flurry of activity from President Donald Trump’s administration. Trump, via Twitter, promised to launch an investigation into illegal voting and threatened to “send in the Feds” if Chicago police can’t fix the “carnage.” And that was just between Tuesday and Wednesday.

This heightened scrutiny compelled the Internet Archive, a repository of everything posted on the web, to launch its Trump Archive in early January. You, perhaps, digitally time-traveled with the Internet Archive’s Wayback Machine, or checked out free books, movies and software. The Trump Archive, which draws content from The Internet Archive’s TV News Archive, includes more than 520 hours of televised Trump speeches, interviews, debates and other broadcasts tracing back to 2009. It will continue to grow. Read More

The Underrated Genius of Neanderthals

For the last dozen years or so, Geico Insurance has run commercials featuring Neanderthals in modern contexts. The story line varies, but the take-home point does not: Switching to Geico is so easy that “even a caveman can do it,” says the tag line. The Neanderthal’s feelings are invariably hurt, and a stereotype gets perpetuated. Do Neanderthals really deserve such derision?

Popularly known as “cavemen,” Neanderthals were ancestral humans who lived in Western Europe, on the eastern shores of the Mediterranean, and in southwestern and central Asia from about 400,000 to 40,000 years ago. They lived in glacial environments during the Ice Age as well as in warmer time periods. Their foreheads were low and receding in contrast to the high, almost vertical foreheads of modern humans. They also had protruding faces and heavy brow ridges above their eyes. While it’s an open question whether you’d recognize a Neanderthal if you saw one on the street, groomed and dressed in modern clothes, I like to think they’d blend in at my museum’s holiday party.
