A company called nanoFlowcell has revealed a concept sports car which gets its energy from salt water and can run up to 621 miles on this electricity alone - wow!
In an attempt to make programming more attractive, MIT has developed a stunning “robot garden”, dozens of fast-changing LED lights and more than 100 origami robots that can crawl, swim, and blossom like flowers. I’ll tell you, if this doesn’t make kids want to code… nothing will! The “garden” was created by a team from MIT’s Computer […]
Beekeeping can be quite difficult, but thanks to a new invention – it just got a lot easier. Stuart and Cedar Anderson, a father-and-son developed a tap system which allows the honey to be harvested without actually disturbing the bees. The Flow Hive not only reduces bee stress, but also eliminates one of the most laborious […]
Languages like English, Greek or Hindu, all Indo-European tongues, stem from a common ancestral language family which originated 5,500 - 6,500 years ago, on the Pontic-Caspian steppe stretching from Moldova and Ukraine to Russia and western Kazakhstan. The findings were reported by a group of linguists at University of California, Berkeley after data from more than 150 languages were analyzed. Today, some 3 billion people speak the more than 400 languages and dialects that belong to the Indo-European family.
Many scholars who still seek to explain why more women leave the science, technology, engineering and mathematics (STEM) pipeline than men are stuck in old times. If in the 1970s, men were 1.6 to 1.7 times as likely as women to later earn a STEM Ph.D., by the 1990s the gender gap had closed and both sexes are as likely to complete their education. Efforts to bridge the gap and promote gender diversity have thus been fruitful. There's still gender gap in STEM among those who first enroll in college, with roughly three times as many men than women.
British researchers have demonstrated three ways gold nanotubes can be used against cancer: 1) high resolution in-vivo imaging; 2) drug delivery vehicles; 3) agents that destroy cancer itself. Their work shouldn't be viewed as yet "another" hack that seeks to eradicate cancer. We need to be more realistic than this. Instead, the findings have the potential to be a great measure that both diagnoses and treats cancer at the same time, complementing conventional surgery and, hopefully, avoiding the need for chemotherapy.
According to a new study, limpet teeth may be the strongest material known to man, stronger than spider silk or kevlar. Scientists from Portsmouth University made the surprising discovery after analyzing limpets with a technique called atomic force microscopy.
At this years' Innovative Advanced Concepts (NIAC) Symposium, NASA's Glenn COMPASS Team discussed at large the possibility of exploring Titan, Saturn's largest moon, with a robotic submarine that would dive deep inside the oceans of liquefied natural gas. Such a mission, if ever funded, could help answer some important questions like what are the defining chemical building blocks required to birth and sustain life. Titan is very similar to Earth in terms of cycling systems, elemental composition and terrestrial geography, so there's much insight to be gained.
A rare Neolithic-era burial site was discovered by the northern entrance of the Alepotrypa (“Foxhole”) Cave in southern Greece. The skeleton remains show how a couple was laid to rest in embrace, close to a burial of another male and female who were found in fetal position - the most common burial position during the Neolithic. The embracing couple’s skeletons were dated with the C14 method to 3800 BC while their DNA analysis confirmed the remains were those of a male and female.
Although mammals surfaced only 20 million years after the first dinosaurs evolved, there's a general consensus that mammals were shadowed and reclusive in the face of dinosaurs, seeing how they were the dominant animals on the planet back then. As such, early mammals are thought to have been mostly nocturnal with minimal interaction with dinosaur environments, occupying very limited ecological niches. This conventional thinking might be toppled by recent findings made by Chinese paleontologists who discovered two highly sophisticated early mammals each at least 160 million years old: the first tree-clinging mammal and the first burrowing mammal. These creatures munched on the same plants dinosaurs did, proving they seemingly coexisted in the same ecological framework.
Chinese researchers ran simulations and found that a pentagon-containing version of graphene is theoretically stable. The 2D allotrope of carbon is made up of atom-thick sheet of carbon atoms arranged in a repeating pentagon pattern, while graphene is made up of carbon atoms arranged in a hexagon pattern, like a chicken wire. Graphene is the strongest material in the […]
When he was a teenager, Keahi Seymour set out to devise a pair of boots that might help him run as fast an ostrich, one of the fastest land animals on Earth, able to reach top speeds of up to 45 mph. We've all had out teenage fantasies, but while most people quit after their first half-baked paper airplanes, Seymour pressed on and I couldn't be more happy for him. Many years later, he finally got to a working prototype called the Bionic Boot - the "transportation / fitness device for the 21st century," by Seymour's account. The video below offers a glimpse of what the boots can do.
Researchers have theoretized for some time that our languages are skewed towards happy words - with some more skewed than others. A new study conducted on 10 different languages confirmed this idea, and also found that Spanish is the happiest language, while Chinese is the most balanced.
Using only energy from the sun, a pioneering artificial leaf system splits water to generate hydrogen - a highly energy dense fuel. When Daniel Nocera, then a professor at MIT, announced his device for the first time four years ago, people were really hyped about it but it soon became clear that making hydrogen was only part of the solution. "The problem with the artificial leaf," Nocera says, is that "it makes hydrogen. You guys don't have an infrastructure to use hydrogen."
The most efficient solar cells are those that convert incoming concentrated solar power via lenses, the sort you see on the International Space Station or in the sun-soaked Middle East where Shams 1, a 100 MW CSP plant – the largest in the world – operates, powering 20,000 United Arab Emirates homes. Because of their complex nature, […]
A PhD student from Netherlands has demonstrated a technique which could massively cut down the production costs of graphene. With this technique, producing the “wonder material” could be 1,000 times cheaper. For his thesis, Shou-En Zhu from the Delft University of Technology described a way to create an “endless sheet” of graphene. The way he does it […]
What is it like to see for the first time? Most of us can't even imagine that, because it happened when we were babies and we can't recall our first visual memories. But Kathy Bleitz, a Canadian woman, certainly will - for the first time, she was able to see using a new technology called eSight. The first thing she saw was her baby.
In the video above, you can see PhD student Mason Bretan from the Robot Musicianship Group at Georgia Tech in the US jam with some of the robots he helped create. The robots got rhythm, and they got the skills. Just look at that amazing marimba solo at the middle of the video – that was completely […]
Divers off the coast of Norfolk have discovered a submerged prehistoric forest, hidden underwater for 10,000 years. The forest was part of Doggerland – a land area which connected Germany and Great Britain up to 8000 years ago. This is a forgotten part of Europe, hidden under 200 meters of water. Divers discovered it after […]
A team of researchers has managed to make metallic glasses from pure, monoatomic metals. These metals are amorphous like glass, but they retain some of the properties of metals - like ultrafast cooling and solid state reaction.
SpaceX, the company responsible for shipping cargo on and off the International Space Station, which wants to implement global access to the internet with a swarm of satellites, has confirmed a $1 billion investment from Google and Fidelity.
Inspired from mud daubers (a species of wasp), designer Massimo Moretti managed to develop a new 3D printing technology for creating cheap houses. Working with architects, he developed bio-architecture which may go a long way towards fighting the housing crisis in some parts of the world.
Princeton researchers demonstrated a novel type of microwave laser - called a maser - so small that's the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.
German researchers have designed shoe devices which harvest power as you walk. The technology could be used to power wearable electronic sensors without the need for batteries.
Despite ebooks and their corresponding electronic reading devices have become extremely popular, surprisingly most young adults and children prefer reading in print than digitally. Moreover, this trend seems to be on the rise after a momentary preference for ebook readers.
Half of young drivers who were killed in car crashes in the United States had consumed alcohol, marijuana or both. Out of the 7,191 fatal accidents studied, 36.8 percent were under the influence of alcohol, 5.9 percent used only marijuana and 7.6 percent used both substances. Researchers analyzed accidents involving drivers between the ages of 16 and […]
Researchers at Stanford University coated flexible textile fibers with metallic nanowires to form a cohesive network that acts as a fantastic thermal insulator. The flexible material, made of silver nanowires and carbon nanotubes, is knitted together so closely that the space between individual strands is smaller than the wavelength of infrared radiation. As such, the radiation emitted by our bodies bounces between the skin and cloth.
A novel type of nanowire crystals was demonstrated by researchers at the University of Copenhagen that can fuse together both semiconductor and metallic materials with atomic precision at their interface. This way, nanowires and their electrical contacts have been fused in one hybrid material which might lay the foundation for the next generation of semiconductor electronics. […]
Based on fossil evidence and genome analysis, scientists know that the two groups diverged from a common ancestor around 420 million years ago, but we've yet to find actual fossil of it. Things are shaping up though after paleontologists have identified an Early Devonian fish from Siberia, approximately 415 million years old, which bears features of both classes.
Apart from sand castles and elaborate water pranks, many beach goers enjoy drawing in the sand, be it simple doodles, love statements or football pitch size intricate works of arts (you have to check out Tony Plant's work). To put human beach drawing to shame, Disney just unveiled a mechanical rake wielding robot, designed to look like a cute turtle, that can automatically draw any planar shapes with ease.
Researchers have found that just by analyzing your Facebook Likes, a computer can judge your personality better than even your close friends. They went even further than that, and calculated how many Likes the algorithm has to analyze to figure your personality traits.
We’ve come to understand that human players will never stand a chance against a computer with enough fire power at finite and open games like checkers or chess. Poker is sensibly different because the computer doesn’t know his human opponent’s hands. No matter, a group of computer scientists from the University of Alberta in Canada […]
Researchers at Northwestern University and the University of Illinois at Urbana-Champaign recently demonstrated a new technique for building complex and very fine 3D micro and nano structures out of 2-D shapes. The whole process is very similar to how a children’s pop-up book works, starting as a flat 2D surface only to expand into a 3D shape when prompted. The authors note that the pop-up method has various advantages over 3D printing, including use of multiple materials during the fabrication process and integration with electronics.
By combing biomechatronics and aesthetics, William Root developed a prototype that's a custom fit for each wearer, uses a minimal amount of top class materials and assures high mobility, all while looking as fit it came off a SciFi movie.
Major automaker Toyota announced at this year’s Consumer Electronics Show in Las Vegas that it would release all of its nearly 6,000 patents pertaining to hydrogen car technology royalty-free for the next five years. Officials most likely hope that this sort of move will encourage other auto manufacturers and capital to invest in the hydrogen economy. […]
For the very first time, engineers have used the DNA origami assembly method to build complex DNA-based mechanism that performs a repeatable and reversible function. Mechanical engineers at The Ohio State University built their devices such that they may function like any regular macro-object, like opening and closing hinges. Their approach, however, is different than other […]
More than 2.5 billion people around the world lack access to clean water, making them vulnerable to diseases. To help address this delicate world problem, the Bill & Melinda Gates Foundation has funded Janicki Bioenergy to build the Omniprocessor – a self-contained system that processes nasty sludge and turns it into electricity, pathogen free ash and pure water. […]
It’s not Jedi technology, but it’s pretty close – scientists and students from China have devised an umbrella that eliminates the need for awkward and hard to wield umbrellas; the technology creates a force-field of air around you to shield you from the rain. We first wrote about this technology in June 2013, when the technology was […]
Some findings are just counterintuitive. I mean, you’d think that adding water to materials would always make them softer, right ? Well according to Yale researchers, that’s not necessarily the case. The team found that you could improve the strength of a composite by 30 percent by embedding droplets of water into its structure. Adding pockets […]
We’ve probably all experienced it at some point – you really have no reason to stay online… but you do so nonetheless. But six percent of the global population actually suffers from internet addiction (IA). Addiction is defined as a substance or activity which is initially pleasurable, but the continued use/act of which becomes compulsive and […]
The latest in brain-computer interface technology was recently demonstrated after woman with quadriplegia shaped a sophisticated robotic hand with ten degrees of freedom using her thoughts. Through the interface, she instructed the robotic hand to move up, down or sideways, pick up small or big objects and even squeeze them. In just a couple of years, […]
The United States Department of Defense just demonstrated one of the scariest weapons ever – a ‘magic bullet’ that can change trajectory in mid flight on command and hit a target no matter what. Shots can be fired from as far as 1.2 miles, and snipers can remain hidden without risk of getting spotted. In fact, […]
Security experts have devised a novel authentication system that exploits quantum effects to make fraud-proof credit cards or IDs. Called Quantum-Secure Authentication (QSA), the technology relies on the quantum properties of single light beams, called photons, including their ability to be in multiple places at once. Quantum physics keys “We experimentally demonstrate quantum-secure authentication (QSA) of […]
Superconductivity or zero electrical resistance at room temperature is any physicist’s dream, but so far the challenges have proven too great. Typically, metals like mercury become superconductive at temperatures close to absolute zero or -273 degrees Celsius. This means that we need to add a lot of energy to refrigerate the material so we might […]
Unfortunately, Derby the husky cross wasn’t born like other dogs. While her back paws are normal and well developed, a deformity caused him to be born with small and very twisted forelegs. He couldn’t walk at all. But Derby caught a break when she was adopted by Tara Anderson, who works for a 3D printing company called […]
Microscopes have gone a long since Zacharias Jansen first invented them in the 1590s. Besides optical telescopes, we now have digital microscopes, atomic force microscopes or, my favorite, electron microscopes. Now, it may be the right time to add a new class to the list: holographic microscopes. While these have been investigated for some time, […]
An expedition that drilled 2,400m beneath the seabed off Japan – the deepest marine drilling ever – found life in cores brought back to the surface. The tiny, single celled organisms survived there without any oxygen or light, relying only on a harsh diet of hydrocarbons to make means. Because of the limited resources available to […]
One of the most interesting projects in science today are the BRAIN Initiative in the US and the Human Brain Project in Europe, which aim to map all the synapse connections in the human brain, or connectome, and ultimately simulate it. It’s an ambitious project with numerous challenges, but the possible benefits are well worth […]
Have you ever wondered how an ink drop blasted by a laser looks like? Physicist Hanneke Gelderblom of the University of Twente in Enschede, Netherlands did! She and her team have won the American Physical Society’s 2014 Gallery of Fluid Motion competition for this technique which is not only super cool, but may one day lead to better […]
Moore’s law says that the number of transistors in an integrated circuit doubles every two years, hence doubling also the computing power. Since it was first predicted in 1965, this trend has hold true allowing computers to evolve at an exponential rate. To support the law, scientists tweak one or all of these three main […]
