A team of French and English researchers recently showcased a prototype phone case called Skin-On, which not only mimics the look and feel of human skin, but also enables interaction communication through gestures like pinching or tickling.

Developed by researchers at the University of Bristol in partnership with Telecomm ParisTech and Sorbonne University, Skin-On consists of a layer of stretchable copper wire in between two different forms of silicone layers. The materials are mass-produced, and the creators of Skin-On claim that the cost of a commercial version of the case would be around $6.5. While anyone could build it, project leader Marc Teyssier admitted that finding the right balance to create what is essentially artificial skin was challenging, considering the case was also supposed to detect touch. But why bother making a smartphone case that everyone generally agrees is “decidedly creepy”. Dr Anne Roudaut, Associate Professor in Human-Computer Interaction, explains:

Consuming a fluid secreted by cockroaches may not be everyone’s idea of a balanced meal, but scientists believe that the “cockroach milk” produced by a certain species of cockroaches is one of the most nutritious substances on the planet, and could one day become the ultimate superfood.

Unlike most other insects, the Pacific beetle cockroach is viviparous, meaning the female give birth live babies that have developed within their body, instead of laying eggs. But a few years ago, while studying these fascinating insects, scientists discovered something even more remarkable – as the embryos grow inside the female cockroach’s body, she feeds them a pale, yellow liquid “milk” from her brood sack. Research has shown that this “cockroach milk” has three times the energy content of buffalo milk, making it one of the most nutritious substances on Earth.

Scientists at Bar-Ilan University’s Institute of Nanotechnology and Advanced Materials, in Tel Aviv, Israel, claim to have created some truly revolutionary eye-drops that can heal damaged corneas and improve vision.

Described as “a new concept for correcting refractory problems”, the nanodrops developed by ophthalmologist  Dr. David Smadja and a team of scientists from Shaare Zedek Medical Center and Bar-Ilan University have so far been tested on pigs with damaged corneas. During a recent presentation, Smadja said that the eye-drops repaired the pigs’ corneas, producing improvements in both short-sightedness and long-sightedness.

According to a research paper published recently in the Journal of Ethnobiology, several Australian birds of prey have the habit of starting wildfires for the soul purpose of flushing out prey from the blazing grasslands. Interestingly, aboriginals have known about this for over 40,000 years and even have a name for the fire-wielding birds – “firehawks”.

Australia’s dry climate makes it prone to wildfires. Lightnings and human activities are considered the main causes, but according to a recently-published research paper, birds may sometimes have a part to play as well. Raptors like the black kite (Milvus migrans), whistling kite (Haliastur sphenurus), and the brown falcon (Falco berigora) can allegedly start fires in the continent’s 730,000 square miles of savanna by dropping burning sticks in the dry grass to flush out prey like insects, reptiles and small mammals. What’s even more remarkable is that they seem to be doing it on purpose.

MIT researchers have made an important breakthrough in their quest to make plants that glow in the dark a reality. In what they call Plant Nanobionics, the engineers embedded nanoparticles into the leaves of a watercress plant that caused the plants to give off a dim glow for three and a half hours.

Their next goal is to create plants bright enough to illuminate a workspace, but, if successful, the technology could also be used to transform trees into self-powered streetlights, the scientists claim. The team’s ultimate goal is to engineer plants to replace many of the functions currently performed by electrical devices and appliances.

“The vision is to make a plant that will function as a desk lamp — a lamp that you don’t have to plug in. The light is ultimately powered by the energy metabolism of the plant itself,” said Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of a recently released study on plant nanobionics.

Cancer therapy is known to cause patients’ hair to fall off, but a few new cancer drugs apparently have a completely different side effect – they restore pigment in older people’s gray hair.

Spanish researchers testing three new cancer drugs – Keytruda, Opdivo and Tecentriq – for negative side-effects in cancer patients made a very surprising discovery. After using the drugs, 14 of the 52 patients involved in the study saw their gray hair go brown or black again. The findings were recently reported in a paper published in the JAMA medical journal.

For the past four decades, billy barr – he insists his name be written with lower case letters only – has been living by himself in Gothic, Colorado, a ghost town deserted since the 1920s, passing the time by recording all sorts of data, from daily snowfalls, temperatures, snow melting, animal sightings, etc.. He never imagined that the results of his 40-year hobby would one day help scientists better understand global warming and earn him a cool superhero name – The Snow Guardian.

billy bar first came to Gothic in 1972 as a Rutgers University environmental science student doing water chemistry research. He liked the quiet life here so much that he completed his semester to get his degree and became a permanent resident of the mountainous ghost town. He had grown up in New Jersey, but never really liked being surrounded by so many people, so moving to this secluded ghost town was a chance to get away from social pressure. “I grew up in the city. It was too much for me,” he says.

barr began the winter of 1974 camping in a tent, which is not exactly ideal in a place where snow reaches twenty-five feet a year. Luckily, the owner of an abandoned mining shack was kind enough to let billy move in, to keep him from freezing to death. It became his home for the next eight years, and also the place where he started his impressive database on snow. The modern-day hermit claims that the sole goal behind his epic journal was to fight boredom. There’s not a lot to do in a ghost town in winter time, so he just started monitoring things like daily snowfalls, snow density, temperature, and anything else he could measure. “I didn’t have anything else to do. It was simple curiosity,” billy says.

It might sound like a silly idea, but it turns out that drawing eyes on the rumps of cattle might deter lions from attacking and prevent human retaliation against the mighty predators.

It sounds like a strategy to protect the poor cattle, but the idea is actually to protect endangered African lions from human retaliation. The majestic felines are on the IUCN Red List of Threatened Species, with numbers currently in the range of 23,000 to 39,000 and rapidly declining. “As protected conservation areas become smaller, lions are increasingly coming into contact with human populations, which are expanding to the boundaries of these protected areas,” says Dr Neil Jordan, a conservation biologist from UNSW’s Centre for Ecosystem Science. The lions attack livestock, and with no non-lethal way of protecting their livelihood farmers often shoot or poison the predators in retaliation.

To help humans and their cattle coexist with lions, Jordan has come up with a low-cost strategy that he hopes will prevent attacks and retaliatory violence. The idea behind painting a pair of intimidating eyes on the rumps of cows is that they will trick the lions into thinking they’ve been spotted, causing them to abandon the hunt. Scientists know that being seen can deter some species from attacking their prey. For example, Indian woodcutters have long been wearing worn masks on the back of their heads to trick man-eating tigers that they’ve been spotted, and butterflies with eye-patterns on their wings ward off predatory birds.

When MIT-trained engineer Todd Rider revealed his revolutionary idea for killing virtually any virus, everyone from fellow scientists to The White House praised him for his results, with some going as far as to call his discovery the most important medical breakthrough since antibiotics. Yet four years later, Rider is struggling to find funds for his research and has to turn to online crowdfunding for something that could save the lives of millions.

The story of Todd Rider’s quest to rid the world of viruses began over 15 years ago, when, while in the shower, he came up with a radical idea in his head – what if there was some way to kill viruses by flipping their biologic suicide switches leaving the patient healthy and infection free? For the next decade, he and his colleagues worked on the concept of Broad-Spectrum Antiviral Therapeutics, which proposed a whole new approach to tackling viruses. Instead of containing and preventing viral infections, their method actually killed virus-infected cells, without harming normal cells.

In early tests, this new weapon dubbed Double-stranded RNA (dsRNA) Activated Caspase Oligomerizer (DRACO), eliminated 15 pathogens, from the common cold to H1N1 influenza to hemorrhagic fevers like the dengue virus. It proved effective across 11 human cell types, including heart, kidneys and liver, and mice infected with lethal doses of influenza virus were cured with DRACO treatments.

It may seem inconceivable, but believe it or not, there really is such a thing as transparent wood. After decades of work, scientists at the KTH Royal Institute of Technology in Stockholm have finally managed to create a viable material that, if mass produced, holds the potential to revolutionize architecture and solar technology.

According to researchers, transparent wood is a low-cost, renewable resource, which can help reduce the cost of indoor lighting and can even be used to make solar-cell windows. It can also be used to make ‘privacy windows’ that let the light in while maintaining semi-transparency.

“Transparent wood is a good material for solar cells, since it’s a low-cost, readily available and renewable resource,” said Lars Berglund, a professor at KTH’s Wallenberg Wood Science Center. “This becomes particularly important in covering large surfaces with solar cells.”

A cat with an accent sounds like a character in a whimsical children’s tale, but Swedish scientists are trying to figure out if domestic cats actually do have differing ‘dialects’ based on their geographical location. They also want to understand if the owner’s voice might have a role to play in the way cats’ meow. If they’re successful, the team of scientists from Lund University hope to put together a ‘dictionary’ of cat sounds.

“It seems that cats can consciously vary their intonation or melody constantly, perhaps to convey a certain message, perhaps to alter or increase the urgency of a message, or emotions,” said Susanne Schötz, a reader in phonetics and head of the project. “We want to find out to what extent domestic cats are influenced by the language and dialect that humans use to speak to them, because it seems that cats use slightly different dialects in the sounds they produce.”

The project, titled ‘Meowsic’ (short for ‘Melody in Human-Cat Communication’), will be carried out over the next five years. Schötz explained that she and her team will use phonetic analysis to compare cat sounds from two parts of Sweden – Stockholm and Lund – with differing human dialects, and figure out if the cats from these regions also have different dialects. They will focus on intonation, voice, and speaking style in the human speech that is addressed to cats, and also cat sounds that are addressed to humans.

In a bid to find a remedy for bedbugs, Canadian scientist Regine Gries has spent nearly a decade studying the parasitic creatures. In fact, she is so dedicated to the project that she actually allows thousands of hungry bedbugs feast off her own blood! Thankfully, her efforts have paid off – she and her husband Gerhard have perfected a chemical that is capable of luring bedbugs away from mattresses.

Regine and Gerhard are both biologists at Simon Fraser University, just outside of Vancouver, in British Columbia. Their lab features a Plexiglass-walled colony with about 5,000 bedbug residents. The bugs live inside glass jars – about 200 to a jar – each covered with a fine mesh that’s held in place using rubber bands. And once a month for the past nine years, Regine has rolled up her sleeves, inverted the jars on to her arms, and allowed the bedbugs to reach through the mesh to bite into her skin!

Denmark’s economy might not be in tip-top shape right now, but that hasn’t deterred northern country’s government from awarding 2.5 million Danish kroner ($430,000) in grant money to a study that investigates the existence of underground trolls (mythical creatures, not internet haters).

The money will be received by Lars Christian Kofoed Rømer, a PhD student and part-time anthropology lecturer at the University of Copenhagen, who has spent two years studying ghost activity. With the new funds, he now plans to research ‘actual relationships’ between humans and trolls on the Danish island of Bornholm.

Bornholm is well-known for its flourishing tourism industry, which is mostly centered around the belief that the island is inhabited by trolls who live underground and come out at night. They even have a ‘national troll’ named Krølle Brølle, who is ‘small and cute’ and lives with his troll family on Langebjerg, and comes out at night to have ‘many exciting adventures’.
