Relief for Couch Potatoes, Canine Contraceptives and One Charmingly Alarming Solution


Losing the remote is so last year with the new device that detects hand movements to control a television. Australian researchers have developed a box that can recognize seven different hand motions, from the thumbs up to an outstretched hand, to signal different commands for a television, DVD player or video recorder. The device supposedly works in any light and from a range of distances. Once the researchers get the box small enough to fit on a television, we'll finally be able to watch TV without all that hassle of actually lifting up a remote.

All those style-blind guys out there trying to match ties and shirts have help on the way. HP has announced a research project that would allow people to use their camera-phone to match colors. After sending a picture of themselves or an object they want to match, users will receive a text message a few minutes later with color recommendations. The pictures are processed and analyzed pixel-by-pixel for color value, erasing the effects of bad lighting. HP officials say the new tool will help women trying to buy makeup, but I can guarantee I'll use it almost every day to figure out what color shirt I should wear with my jeans.

caddyshack12.jpgMembership at your country club might get a little less exclusive if a team of American scientists has their way. They're advocating that golf courses be used as animal sanctuaries, since 70 percent of the well-manicured land isn't even used for playing. The greens are ideal places for animals, since they can be altered to mimic natural habitats and would be protected. On the other hand, this idea opens the door to all kinds of Caddyshack gopher-style animal hijinx.

Snow in Buenos Aires?!
I'll admit, after living my entire life up north where winters are cold and snow is common, I can't empathize with people who joyfully greet every flurry by trying to have a snowball fight. But even my heart was warmed by the story of Buenos Aires getting its first taste of snow in almost 90 years. There have been cold temperatures plaguing Argentina since May, but a moisture-laden system moving in caused the snowfall on Argentina's Independence Day, the city's first since 1918. Sure, the story is dampened by the 23 deaths from exposure to cold, the energy crisis that has hit the country in light of the cool temperatures and the knowledge that this is just more evidence of how screwy our weather system has become, but the thought of Argentine children making snow angels is too much to not be happy.

nasal spray.jpgBoost Your Confidence, Via Nose
We've all been told that the best way to get over a fear of public speaking is to imagine everyone in their underwear. Apparently, the second-best way is a confidence-boosting nasal spray. Australian researchers developed the spray, which releases oxytocin into the bloodstream. In tests of 70 men and women, the drug was shown to reduce shyness in stressful social situations. Following large-scale tests, the spray should be commercially available in five years, so shy guys will finally have the courage to talk to girls at the bar after putting a little something up their nose. Sounds like a totally novel idea that will do great in the 1980s.

Neuter no more
Until now, dog birth control has been pretty one-sided; it's either neuter or nothing. But now an Australian company has unveiled a contraceptive implant for use in male dogs that will curb testosterone for months at a time, leaving a less permanent and relatively more comfortable alternative. The implant controls the hormone linked to testosterone production, not only killing the dog's sex drive, but also relaxing his aggressive behavior. Dogs aren't quite out of the water yet; the company still urges neutering as the best option if the owners don't want any breeding.

Don't worry, I'm not talking about proposing. Since I reward myself for enduring the obnoxious buzz of my alarm clock with five more minutes of sleep, I think I might be in line for this sleek alarm from Yanko Design. The alarm is actually a ring that can be programmed to vibrate at a certain time. The vibrations of the ring then awake you in a manner slightly less jarring than the blaring horn of most clocks. This innovative alarm is especially useful for the hearing-impaired and couples waking up at different times.

Your $10 Donation Can Help an Underprivileged Child See A Wrinkle in Time for Free
Disney Enterprises, Inc.
Disney Enterprises, Inc.

Theater chain AMC is teaming with the Give a Child the Universe initiative to help underprivileged kids see A Wrinkle in Time for free through ticket donations. The initiative was started by Color of Change, a nonprofit advocacy group that designs “campaigns powerful enough to end practices that unfairly hold Black people back, and champion solutions that move us all forward.”

"Color of Change believes in the power of images and supports those working to change the rules in Hollywood so that inclusive, empathetic and human portrayals of black people and people of color are prominent on the screen,” the initiative’s executive director, Rashad Robinson, said in a statement:

Director Ava DuVernay’s A Wrinkle in Time is the perfect subject for the group because, as Robinson puts it, “By casting a black teenage actress, Storm Reid, as the heroine at the center of this story, the filmmakers and the studio send a powerful message to millions of young people who will see someone like them embracing their individuality and strength to save the world.”

The movie touts a diverse cast that includes Mindy Kaling, Oprah Winfrey, Reese Witherspoon, Zach Galifianakis, and Chris Pine. The most important member of the cast, though, is 14-year-old Storm Reid, who plays the main character Meg Murry, a young girl who tries to save her father (Pine) who is trapped in another dimension. The movie is based on the acclaimed 1962 fantasy novel by author Madeleine L'Engle.

If you’d like to donate a ticket (or more), you can just head over to the Give a Child the Universe website and pledge an amount. AMC will provide one ticket to children and teens nationwide for every $10 given to the cause.

And if you’re interested in seeing the movie yourself, A Wrinkle in Time opens on March 9, 2018.

Head Case: What the Only Soft Tissue Dodo Head in Existence Is Teaching Scientists About These Extinct Birds

Of all the recently extinct animals, none seems to excite the imagination quite like the dodo—a fact Mark Carnall has experienced firsthand. As one of two Life Collections Managers at the UK's Oxford University Museum of Natural History, he’s responsible for nearly 150,000 specimens, “basically all the dead animals excluding insects and fossils,” he tells Mental Floss via email. And that includes the only known soft tissue dodo head in existence.

“In the two and a bit years that I’ve been here, there’s been a steady flow of queries about the dodo from researchers, artists, the public, and the media,” he says. “This is the third interview about the dodo this week! It’s definitely one of the most popular specimens I look after.”

The dodo, or Raphus cucullatus, lived only on the island of Mauritius (and surrounding islets) in the Indian Ocean. First described by Vice Admiral Wybrand van Warwijck in 1598, it was extinct less than 100 years later (sailors' tales of the bird, coupled with its rapid extinction, made many doubt that the dodo was a real creature). Historians still debate the extent that humans ate them, but the flightless birds were easy prey for the predators, including rats and pigs, that sailors introduced to the isolated island of Mauritius. Because the dodo went extinct in the 1600s (the actual date is still widely debated), museum specimens are very, very rare. In fact, with the exception of subfossils—the dark skeletons on display at many museums—there are only three other known specimens, according to Carnall, “and one of those is missing.” (The fully feathered dodos you might have seen in museums? They're models, not actual zoological specimens.)

Since its extinction was confirmed in the 1800s, Raphus cucullatus has been an object of fascination: It’s been painted and drawn, written about and scientifically studied, and unfairly become synonymous with stupidity. Even now, more than 300 years since the last dodo walked the Earth, there’s still so much we don’t know about the bird—and Oxford’s specimen might be our greatest opportunity to unlock the mysteries surrounding how it behaved, how it lived, how it evolved, and how it died.

 
 

To put into context how old the dodo head is, consider this: From the rule of Oliver Cromwell to the reign of Queen Elizabeth II, it has been around—and it’s likely even older than that. Initially an entire bird (how exactly it was preserved is unclear), the specimen belonged to Elias Ashmole, who used his collections to found Oxford’s Ashmolean Museum in 1677. Before that, it belonged to John Tradescant the Elder and his son; a description of the collection from 1656 notes the specimen as “Dodar, from the Island Mauritius; it is not able to flie being so big.”

And that’s where the dodo’s provenance ends—beyond that, no one knows where or when the specimen came from. “Where the Tradescants got the dodo from has been the subject of some speculation,” Carnall says. “A number of live animals were brought back from Mauritius, but it’s not clear if this is one of [those animals].”

Initially, the specimen was just another one of many in the museum’s collections, and in 1755, most of the body was disposed of because of rot. But in the 19th century, when the extinction of the dodo was confirmed, there was suddenly renewed interest in what remained. Carnall writes on the museum’s blog that John Duncan, then the Keeper of the Ashmolean Museum, had a number of casts of the head made, which were sent to scientists and institutions like the British Museum and Royal College of Surgeons. Today, those casts—and casts of those casts—can be found around the world. (Carnall is actively trying to track them all down.)

In the 1840s, Sir Henry Acland, a doctor and teacher, dissected one side of the head to expose its skeleton, leaving the skin attached on the other side, for a book about the bird by Alexander Gordon Melville and H.E. Strickland called The dodo and its kindred; or, The history, affinities, and osteology of the dodo, solitaire, and other extinct birds of the islands Mauritius, Rodriguez and Bourbon. Published in 1848, “[It] brought together all the known accounts and depictions of the dodo,” Carnall says. The Dodo and its kindred further raised the dodo’s profile, and may have been what spurred schoolteacher George Clark to take a team to Mauritius, where they found the subfossil dodo remains that can be seen in many museums today.

Melville and Strickland described Oxford’s specimen—which they believed to be female—as being “in tolerable preservation ... The eyes still remain dried within the sockets, but the corneous extremity of the beak has perished, so that it scarcely exhibits that strongly hooked termination so conspicuous in all the original portraits. The deep transverse grooves are also visible, though less developed than in the paintings.”

Today, the specimen includes the head as well as the sclerotic ring (a bony feature found in the eyes of birds and lizards), a feather (which is mounted on a microscope slide), tissue samples, the foot skeleton, and scales from the foot. “Considering it’s been on display in collections and museums, pest eaten, dissected, sampled and handled by scientists for over 350 years,” Carnall says, “it’s in surprisingly good condition.”

 
 

There’s still much we don’t know about the dodo, and therefore a lot to learn. As the only soft tissue of a dodo known to exist, the head has been studied for centuries, and not always in ways that we would approve of today. “There was quite some consideration about dissecting the skin off of the head by Sir Henry Acland,” Carnall says. “Sadly there have also been some questionable permissions given, such as when [Melville] soaked the head in water to manipulate the skin and feel the bony structure. Excessive handling over the years has no doubt added to the wear of the specimen.”

Today, scientists who want to examine the head have to follow a standard protocol. “The first step is to get in touch with the museum with details about access requirements ... We deal with enquiries about our collections every single day,” Carnall says. “Depending on the study required, we try to mitigate damage and risk to specimens. For destructive sampling—where a tissue sample or bone sample is needed to be removed from the specimen and then destroyed for analysis—we weigh up the potential importance of the research and how it will be shared with the wider community.”

In other words: Do the potential scientific gains outweigh the risk to the specimen? “This,” Carnall says, “can be a tough decision to make.”

The head, which has been examined by evolutionary biologist Beth Shapiro and extinction expert Samuel Turvey as well as dodo experts Julian Hume and Jolyon Parish, has been key in many recent discoveries about the bird. “[It] has been used to understand what the dodo would have looked like, what it may have eaten, where it fits in with the bird evolutionary tree, island biogeography and of course, extinction,” Carnall says. In 2011, scientists took measurements from dodo remains—including the Oxford specimen—and revised the size of the bird from the iconic 50 pounder seen in paintings to an animal “similar to that of a large wild turkey.” DNA taken from specimen’s leg bone has shed light on how the dodo came to Mauritius and how it was related to other dodo-like birds on neighboring islands [PDF]. That DNA also revealed that the dodo’s closest living relative is the Nicobar pigeon [PDF].

Even with those questions answered, there are a million more that scientists would like to answer about the dodo. “Were there other species—plants, parasites—that depended on the dodo?” Carnall asks. “What was the soft tissue like? ... How and when did the dodo and the related and also extinct Rodrigues solitaire colonize the Mascarene Islands? What were their brains like?”

 
 

Though it’s a rare specimen, and priceless by scientific standards, the dodo head is, in many ways, just like all the rest of the specimens in the museum’s collections. It’s stored in a standard archival quality box with acid-free tissue paper that’s changed regularly. (The box is getting upgraded to something that Carnall says is “slightly schmancier” because “it gets quite a bit of use, more so than the rest of the collection.”) “As for the specific storage, we store it in vault 249 and obviously turn the lasers off during the day,” Carnall jokes. “The passcode for the vault safe is 1234ABCD …”

According to Carnall, even though there are many scientific and cultural reasons why the dodo head is considered important, to him, it isn’t necessarily more important than any of the other 149,999 specimens he’s responsible for.

“Full disclosure: All museum specimens are equally important to collections managers,” he says. “It is a huge honor and a privilege to be responsible for this one particular specimen, but each and every specimen in the collection also has the power to contribute towards our knowledge of the natural world ... This week I was teaching about a species of Greek woodlouse and the molluscs of Oxfordshire. We know next to nothing about these animals—where they live, what they eat, the threats to them, and the predators that rely on them. The same is true of most living species, sadly. But on the upside, there’s so much work to be done!”
