...The new robot consists of two layers of structural material sandwiching a material that shrinks when heated. A pattern of slits in the outer layers determines how the robot will fold when the middle layer contracts....
In the center of one of the forward accordion folds is a permanent magnet that responds to changing magnetic fields outside the body, which control the robot’s motion. The forces applied to the robot are principally rotational. A quick rotation will make it spin in place, but a slower rotation will cause it to pivot around one of its fixed feet. In the researchers’ experiments, the robot uses the same magnet to pick up the button battery.
The researchers tested about a dozen different possibilities for the structural material before settling on the type of dried pig intestine used in sausage casings. “We spent a lot of time at Asian markets and the Chinatown market looking for materials,” Li says. The shrinking layer is a biodegradable shrink wrap called Biolefin.
State medical boards are hybrids: part independent regulator, part industry association. They are in charge of handing down professional probations against doctors who do wrong, but the details of which doctors are on probation, and why, are kept from patients. Read the rest
Ian Burkhart lost all sensation in his hands and legs after a freak swimming accident five years ago. Today, doctors report that a chip in his brain has let him regain some control of his hand. The 24-year-old man has “regained control over his right hand and fingers, using technology that transmits his thoughts directly to his hand muscles and bypasses his spinal injury.”
In 1959, physicians at New York's Maimonides Hospital implanted this dog with a radio receiver in its chest, part of an "auxiliary heart" system that would support a failing ticker. From the March 9, 1959 issue of LIFE:
The booster heart, developed by Drs. Adrian Kantrowitz and William McKinnon (of New York's Maimonides Hospital) is made by lifting up half of the diaphragm muscle and wrap it around the aorta, the body's main artery. Inside the chest a small radio receiver, part of an electronic system that detects and transmits the actual heart's beat, picks up the heart's rhythm and sends it by electric signals down a nerve to the diaphragm flap, making it squeeze the aorta rhythmically. This action, like a heartbeat, pumps the blood.
Kantrowitz, a pioneer in heart transplants, died in 2008.
Today we travel to a future where your microbiome becomes a key part of your identity. From health to your child’s kindergarten, here are all the ways knowing about your microbiome might impact your life.
In this episode we talk about the possibilities and limitations of the microbiome — the trillions of bacterial cells that live in and on your body. There’s a lot of money going towards microbiome research right now, and a whole lot of claims about what the microbiome can do. We break down what we actually know, and where we’re probably going.

Vietnamese gentleman Thái Ngọc claims that ever since he suffered a terrible fever in 1973, he hasn't slept a wink. There's also Ines Fernandez who says she's been awake for decades. Of course, these curious individuals and others with similar stories may actually be suffering from a very strange sleep disorder called sleep state misperception (SSM) in which the individuals think they were up all night but actually slept just fine. At Mysterious Universe, Martin J. Clemens looks at SSM and the very scary rare disease called Fatal Familial Insomnia (FFI), presented as total insomnia that can last the rest of the person's life, which is usually only 18 months or so after the onset of symptoms. From Mysterious Universe:

FFI is a neurological condition caused by a misfolded protein in the DNA of the afflicted, of which there have been only about 100 cases. That protein, called a prion protein, is known as PrPSc (PrPC in non-FFI subjects). Essentially, the prion form of the protein causes a change in certain amino acids – due to the protein strand folding incorrectly – which, when combined with other genetic markers, then affects the brain’s sleep centers. FFI is genetic, and therefore hereditary, but there is an even rarer form known as Sporadic Fatal Insomnia (sFI) that occurs spontaneously, the cause of which is not understood. You may wish to know that PrPSc is the same protein that’s responsible for bovine spongiform encephalopathy, also known as Mad Cow Disease.

My guide for the evening had accepted my 400 dollars, the price for my journey, in tie-dyed pants. It was my own fault I wasn’t tripping very hard—I’d told her, out of nervousness, I didn’t want to travel to other planets—though I suspected she knew less about the “sacraments” she was prescribing to us than she purported to. (“Do you know that Peruvians drip ayahuasca into the eyes of their newborns?” she’d told me earlier. “All Peruvians?” I’d asked, and she’d blushed.) Still, I liked her, partly because there was something in her eyes that made me think of the Wordsworth line from “Elegiac Stanzas”: “A deep distress hath humanized my soul.” I sensed there’d been some suffering in her past. Many of the participants, I noticed, had the same benignly haunted look. An ex-physician told us that ten years ago she’d been diagnosed with advanced-stage cancer; she’d recovered, but couldn’t shake the feeling that it would return any second to finish her off. To allay her lingering fear of death, she’d enrolled in a psilocybin trial, and her “whole reality changed.” She divorced her husband and began to juggle motherhood and what full-time psychonauts call “The Work,” traveling the world to partake in aya ceremonies.

Last year, Mohammed Abad, 43, whose penis was destroyed when he was hit by a car as a child, received an 8-inch implant involving two tubes that inflate his reconstructed flesh phallus when he pumps it up via a button in his scrotum. The implant was the culmination of years of reconstructive surgery. These kinds of implants are commonly used to treat erectile dysfunction. Abad has now announced that he will soon lose his virginity to a sex worker named Charlotte Rose, 35.
“I have waited long enough for this — it’ll be a great start to the new year," Abad said. "My penis is working perfectly now so I just want to do it. I’m really excited. I can’t wait for it to finally happen.”
Rose will travel from London to see Abad in Edinburgh.
"I am so honoured that he chose me to take his virginity," she said. "We plan to have a dinner date so we can get to know each other and then two hours of private time. I’m not charging him.”
David Vetter (1971-1984) suffered from severe combined immunodeficiency (SCID), a disease that required him to live inside a sterile environment, a plastic "bubble." Eventually, he tested a special suit developed by NASA so that he could venture out of his bubble. Vetter's story partially inspired the 1976 TV movie "The Boy in the Plastic Bubble," starring John Travolta (full film below), the asinine 2001 comedy "Bubble Boy," and a Seinfeld episode. Vetter's life and tragic death continues to help physicians understand and treat immunodeficiency diseases.
In 2001, the roof of a flaming building fell on volunteer firefighter Patrick Hardison, burning his firefighting mask onto his head. As a result, Hardison, now 41, has spent more than a decade without a face. Now, Hardison has the face of David Rodebaugh, a 26-year-old who died in a bicycling accident and donated much of his body for transplant. Surgeon Eduardo Rodriguez and a team at the New York University Langone Medical Center performed the facial transplant, "the most extensive" in history according to the hospital.
Hardison also received a new scalp, ears, ear canals, chin and cheek bones, and Rodebaugh's nose. Previously unable to close his eyes totally, he now has eyelids and also muscles for blinking.
New York University paid for the transplant, totaling $850,000 to one million dollars.
You've likely read about Italian physician Dr. Sergio Canavero's plan to perform the first human head transplant? There is precedent with non-humans and it ain't pretty. In 1965, Dr. Robert J. White and his colleagues at Cleveland Metropolitan General Hospital transplanted the brain of one dog to another. "The transplant … acted as a second brain in the animal’s neck," according to Science News Letter. In the 1970s, White continued his experiments by transplanting rhesus monkeys' head onto other monkeys' bodies. (See the diagram above.)
Below, a special edition of The Midnight Archive profiles White, discusses similar research in Russia at the time, and touches on the ethical questions around these experiments. (Warning: this video is rather graphic.)

In relation to their heart attacks, only 0.7 percent of participants they'd had sex within an hour before their heart attack and more than 78 percent of participants said they hadn't had sex in at least 24 hours before having the heart attack. Based on this, and a total of 100 adverse cardiovascular events among the participants in 10 years of following up with them, researchers said sexual activity does not appear to be a risk factor for heart attack.
