There aren’t that many people who imagined that in only a couple of years we’d see smartphones with 40MGpx cameras. Amazingly as that may sound, manufacturers are nearing a stand-still as far as optics miniaturization is concerned and even so, high end camera phones don’t come near the quality of a dedicated optical hardware. A […]
Swiss scientists from the University of Bern demonstrated a new device that essentially generates electrical power from the mechanical energy of heartbeats.
Researchers at the Hong Kong University of Science and Technology have created a thin metamaterial surface that is capable of absorbing nearly all of the acoustic energy (sound). Unlike conventional sound absorbing material that is sometimes only effective when meters thick, the metasurface is deeply “subwavelength” and therefore much thinner. There’s a catch though: the system has been demonstrated […]
Researchers from Stanford have found a way to split water into oxygen and hydrogen using very little energy; the hydrogen they obtain could be used to power fuel cells in zero-emissions vehicles. I’m quite excited for cars that run on hydrogen, which are set to hit the market in 2015; but while they are always presented as […]
A team of researchers from the Aarhus University in Denmark and CalTech has developed an origami-inspired method of organizing molecules on the nanoscale. The team has modeled RNA, DNA’s close cousin into complicated shapes using the technique. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for […]
The physical properties of the ultra-white scales on certain species of beetle could inspire researchers to make better, whiter paper, plastics or paint, using far less material. The Cyphochilus beetle, native to South-East Asia, is whiter than paper or even milk teeth. The whiteness of its body is caused by a thin layer of a highly […]
Graphene, the wonder material shows its potential once again: now, using graphene and rubber bands, engineers have created a flexible sensor which has significant medical value and can be made cheaply. You really should know about graphene by now – we’ve written dozens of articles about it just in the past couple of years; but […]
Depending on where you live, bike stealing can be a distant threat or a constant worry, but in most parts of the world, people would rather be safe than sorry, tying their bikes to trees or fences or whatever they could find. But that may very well change in the near future: three engineers from […]
If you thought research in airplanes only applies to the military, you’re wrong. While most of the money spent for airplane research does go to the military, a smaller chunk of it goes to space research, and another part goes to private air travel. Now, a company from the UK has almost developed an engine […]
I just love it when technology can help solve social problems – especially in cases where you wouldn’t expect it to, like for example in Chicago, where a Twitter bot is helping authorities find dirty restaurants. If you’ve eaten out, and after that you feel a bit sick, like say you have an indigestion or […]
Canada’s most famous (and from what I can find, only) beer-cooler turned hitchhiking robot has finally completed its 6,000-kilometre journey across Canada, blazing rides from Halifax reaching Victoria late Saturday; and he did it with style: I’m on a boat. Well, a ferry to be exact. Victoria, I’m on my way. #hitchBOT @BCFerries pic.twitter.com/SPewf9rIq1 — hitchBOT (@hitchBOT) […]
A group of international researchers have demonstrated a novel technique for destroying cancer cells. By inserting a chloride payload that penetrates the cancer cell's sodium membrane, the cells become flushed with salt causing a self-destruction response.
Brown University researchers reported the development of a copper foam which could turn CO2 into useful chemicals such as formic acid – a preservative and antibacterial agent in livestock feed. As CO2 emissions continue to grow, scientists are trying to find potential uses to it. The problem with carbon dioxide is that it is extremely […]
The walking cane has helped the blind navigate obstacles for thousands of years, and its design has remained largely unchanged since - a sophisticated stick. What looks like a combination between a TV remote and a Star Trek tricorder, the Enactive Torch aims to help all the aging baby boomers, injured veterans, diabetics and white-cane-wielding pedestrians navigate their surroundings using 21st century tech.
The brain of complex organisms, such as humans but just as well other primates or even mice, is very difficult to emulate with today’s technology. IBM is moving things further in this direction after it announced the whooping features of its new brain-like chip: one million programmable neurons and 256 million programmable synapses across 4096 individual […]
In 1944, the Nazis caused widespread famine in Western Netherlands after they blocked food supplies. A group of pregnant women living in the Netherlands, labouring under starvation conditions imposed by a harsh winter and food embargo, gave birth to relatively small babies. When their children grew up, in relative prosperity, to have children of their own their babies were unexpectedly small.
This wasn't an easy tasks since the researchers identified hundreds of potential candidate compounds.
I remember when once upon a time, wi-fi could barely reach from one room to the other. It wasn’t even regarded as a serious technology by some back then – but oh my, how times have changed! Now, wi-fi is almost ubiquitous in the developed world, but the problem still remains the same – the […]
Computer games could be the key to treating elderly people who have been diagnosed with depression, but who aren’t responding to conventional treatment. A new study has shown that playing a certain type of computer games was more effective at reducing symptoms of depression than the “gold standard” – the antidepressant drug escitalopram. Recently, we’ve been bombarded about […]
Most University professors still rely on passive lectures to get their subject across. A meta-study which analyzed 225 studies found that active teaching – lectures that actively engage students and make the learning experience two-way – improves grades and significantly reduces fail rates. The findings add to an already body of literature that suggests the […]
Allan Savory's holistic management solution seems too good to be true. Hint: it's not.
If you’ve owned a smartphone or laptop for more than two years and use the gadgets frequently, then you’ve most likely noticed, to your exasperation, how short the battery life is compared to when the product was first shipped. Rechargeable batteries have been around for more than 100 years, but it’s only recently that scientists […]
In the 1980s, concerned that the state statute on prostitution was too broad and could potentially infringe on First Amendment freedoms, lawmakers in Rhode Island decided to make it more explicit by cutting some articles. They went a bit too far, though, and accidentally removed the section defining the act itself as a crime. It […]
If you’ve ever been to London, you might have noticed the city is packed with CCTV cameras even in the least crowded street crossings. Besides 24/7 monitoring, these cameras feed images to a highly complex system that automagically runs face recognition, checks the mugs of pedestrians and runs a check if there’s anything on file […]
At the turn of the 1990s, scholarly publishers were increasingly concerned about what had become known as the serials crisis. Journal subscriptions were rising at an average of 10% per year, which in turn meant each year libraries were struggling harder to keep up and in, consequence, many would cancel. To counter, publishers would further increase […]
The Simpsons Movie’s plot starts off with Homer adopting a messy piglet he names “Spider Pig”. The pig, helped a great deal by Homer, made enough waste to fill a silo in just two days, so how does Homer decide to solve this problem? Naturally, being Homer (doh!), he throws away the silo into the […]
Sverker Johansson could encompass the definition of prolific. The 53-year-old Swede has edited so far 2.7 million articles on Wikipedia, or 8.5% of the entire collection. But there’s a catch – he did this with the help of a bot he wrote. Wait, you thought all Wikipedia articles are written by humans? A good day’s work […]
Expect the price of sand to skyrocket! Researchers at University of California, Riverside have devised a coin-sized battery that uses silicone at its anode (negative side), instead of the over-used graphite, that lasts up to three times longer than conventional lithium-ion batteries. The key of the research is the silicon extraction method which uses quartz-rich […]
A few months ago I went hiking with some of my friends in an absolutely stunning mountain setting. We climbed a country road for half an hour or so on foot, then reached a chalet right in the middle of a pine tree clearing and had a few beers with the keeper there, who was […]
You might have thought black is too solemn or boring, but you may just change your mind. Through careful material science manipulation, involving thousands of tightly packed carbon nanotubes, British company Surrey NanoSystems made a super black coating that absorbs almost 99.96% of visual light – a world record. Practically only a tiny fraction of the visual […]
Since the 1990s, biologists have witnessed a sudden demise of amphibian species. So far, hundreds of species have become extinct after becoming plagued by a wretched fungus. From mountain lakes to meadow puddles, no matter the continent, frogs are dying everywhere – a demise that might spell an ecological meltdown. There may still be hope yet, according […]
If you’ve ever watched chimps during a nature program and became startled by your own empathy towards them, you’re not alone. It’s no secret that chimps are our closest relatives out of all primates, having 98% similar DNA. It goes further than genetics – it’s enough to look a chimp in the eye. The reflection is more […]
Advancements in genetic sequencing has allowed genomic research to flourish. DNA sequencing is now much faster, cheaper and accurate than ever before, and we’re only now beginning to reap the rewards. It’s the first step to a complete understanding of our bodies. The Human Genome Project, once finally completed, mapped and identified all the genes of […]
Materials found in nature often speak of at least one comprise. Metals for instance are highly conductive, but not transparent. Plastics on the other hand can be made to be transparent, but they’re very poor electrical conductors. This annoying tradeoff has aggravated scientists for some time in their efforts to design better solar cells or […]
Professor Terry Dawson of the University of New South Wales and colleagues found that kangaroos use their tail as an extra leg when walking, actively participating with energy in the process, instead of using it like a strut as some literature would had us believe. The findings might prove to be important for robotics applications. Hoppity hop […]
A new species of ground beetle perfectly adapted to extreme environments has been discovered in the world’s deepest cave system, the Krubera-Voronja, in Russia. The insect is about a quarter of an inch long and blind. In fact, given there isn’t light whatsoever reaching it, the bug has evolved extended antennae and a body that has […]
Rashid Bashir, the head of bioengineering at the University of Illinois at Urbana-Champaign, is one of the pioneers leading a new field of robotics which deals with bio-bots. These tiny robots, less than a centimeter in size, combine biological and mechanical components to meet a certain purpose. Recently, Bashir and his team demonstrated a bio-bot […]
Guns today are looking more and more like they’re from a video game or something. Take TrackingPoint’s latest Precision-Guided Firearm (PGF) – a sniper rifle that allows the user to tag targets so that the gun will come off only when the tag is in scope. Actually, considering the rifle doesn’t actually have an optical scope, […]
The PowerCube looks like any other shipping container, but after it unfolds its ‘wings’ you start realizing there’s more than meets the eye. Designing for humanitarian relief efforts, the PowerCube is meant to deliver electrical power, purify water and offer WiFi signal to disaster inflicted areas all through harnessing solar power. While the idea is […]
Germany has reached a new renewable energy milestone recently after the country announced that on a given day an impressive 50.6% of its energy demand was covered by solar energy alone. Breaching this important psychological barrier means a lot of for renewable energy efforts in Germany, and worldwide as well serving as an example. According to […]
Since its advent some 100 years ago, crystallography has become one of the most important processes in chemical research and development. It involves bombarding a material with X-rays to produce a diffraction pattern as they reflect off the sample. The pattern can be used then to directly determine the atomic structure of the crystal. Using […]
In the past years, several types of invisibility cloaks have been developed, hiding objects not only from light, but also from sound and even heat. But this is the first time an invisibility cloak for touch has been developed. Recently, we’ve written quite a lot about invisibility cloaks – how they work, how they can be […]
Chinese doctors have grafted a man’s hand onto his food in order to preserve it until they could transplant it back to its rightful place. If a body part becomes severed from the body, there is only a limited period of time before it can be reattached – usually just 2-3 hours. Adding some ice […]
The new NASA-funded study showed that if the icy surface of Pluto’s giant moon Charon is cracked, analyzing the fractures could show if the interior was warm and perhaps warm enough to have maintained a subterranean ocean of liquid water. Pluto is the most distant planetoid (no longer a planet, sorry) in the solar system. […]
Today, Elon Must, the founder and owner of Tesla Motors announced that they were releasing all the patents they own, for free, for everyone to use. The release of over 200 patents was announced in style, through a blog entry called “All our patents are belong to you“. ” Yesterday, there was a wall of Tesla […]
A brilliant technology reaching its limits Carrying heavier spacecraft to Mars and then safely landing it at supersonic speeds in the Martian atmosphere is no easy feat – and NASA could use any bit of help they can get. NASA’s Wallops Flight Facility is playing an integral role in solving those problems with the Low Density Supersonic […]
Superhydrophobic surfaces are surfaces that not only don’t get wet, but they actually repel water. This is the so-called lotus effect, named after the superhydrophobic leaves of the lotus plant (as usually, nature’s been doing long before we have). We’ve written time and time again about the amazing achievements in the field of superhydrophobics – and […]
When people think of teleportation, inevitably a Star Trek reference like “beam me up, Scotty’ comes to mind. You’ve got to admit though, it’s a really cool idea – how many times did you think about instantly traveling to some place distant? I used to wish for teleportation every single day of my life when […]
What would you need to survive on the Moon? Air, water, some food, and if you ask the average American – wi-fi. We still have to wait for the air, water and food, but according to researchers from NASA and MIT, wi-fi on the Moon is quite feasible. They’ve even made a demonstration, downloading information from […]
The current world land speed record stands at 763.035 mph, as set in October 1997 by British Royal Air Force pilot Andy Green driving the jet-powered Thrust SSC. Green is looking to break his own record and has a new team and a new car behind him, however, called Bloodhound SSC. Green wants to top […]
