Researchers at Purdue University found that a local bus system running on natural gas is more economically feasible and less harmful to the environment than the currently employed diesel model. The team lead by Purdue University energy economist Wally Tyner also concluded that natural gas is a better fit than electric-hybrid. The analysis was was specific […]
Stanford chemical engineers have developed a theoretical model that sheds light on the electrical conductivity properties of polymers. Their work provides a valuable first step for other researchers to build on, providing an experimental setting for those looking to expand the electrical conductivity of certain polymers (typically plastics) for use in the industry. The word […]
A lot of complex organisms, be them long extinct like dinosaurs or still alive like mammals, present what can only be referred to as a face – a symmetrical arrangement on the head of the animal of eyes, nose and, most importantly, jaw and cheek-bones. Human are particularly adapted to recognizing faces. Thanks to our […]
Prosthetics have been around for a very long time – the first mention of such a device is by the warrior queen Vishpala in the Rigveda, which was written roughtly some 3.500 years ago. But even with the spectacular developments of the past century, only in the past couple of decades did prosthetics really start […]
In an inspiring breakthrough, Stanford researchers have created the first ever working computer made entirely out of carbon nanotubes. The technology is still very infant, as the computer operates on just one bit of information, and can only count to 32. Theoretically, however, it can be scaled up to perform billions of operations given enough memory. […]
The Issus coleoptratus or issus for short is a small hopping insect that can leap at tremendous speeds and lengths compared to its tiny size. Actually, it’s one of the fastest accelerating creatures known to biologists, capable of accelerating at nearly 400 g’s—a rate more than 20 times what a human body can withstand. To achieve this […]
Peter Turchin, a population dynamicist at the University of Connecticut in Storrs, and his colleagues finished a study which concluded that war drove the formation of complex social institutions such as religions and bureaucracies. The study showed that these institutions helped give much needed stability to large and ethnically diverse early societies. “Our model says […]
Take a moment to imagine a phone display as clear as a window, a curtain that can illuminate a room, and a smart phone that can stretch like rubber; now imagine all these things are made from the same material. Researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have developed a transparent, […]
When the Sahara comes to mind, lush greenery and gorgeous, fast flowing waters might be the last scenery that crosses you. Not too long ago (geological frame), however, the region known today as the Sahara may have been crossed by three giant rivers the size of the Nile, according to a recent palaeohydrological model made […]
Biofuels are very ‘hot’ at the moment, as they’ve started to gain traction. Production as increased about 400% since 2000, and that’s a good thing. Right? After all, anything that can replace fossil fuels is a better option. Well, not necessarily. A while ago, I wrote a piece for ZME Science in which listed some […]
The 3-d printing industry is growing, and it’s growing darn fast. It’s no wonder why too. We’re on the brink of a small-manufacturing revolution, similar to how inkjet printers revolutionized home offices only at a totally different scale. So, your kid’s toy broke? No need to buy a new one, just print the broken part […]
For the first time in history, scientists from the Florida campus of The Scripps Research Institute (TSRI) have been able to eliminate dangerous drug-associated memories in mice and rats without apparently affecting other memories. Erasing memories If you’ve ever seen The Eternal Sunshine of the Spotless Mind (truly a remarkable movie, which I highly recommend) […]
A common lament we often encounter in today’s society is just how boring some people’s jobs are. We all have friends, or you might be one of these folks yourself, who always seem to complain how unsatisfying their workplace is, even though they might have other options at their disposal. A recent study found that […]
Ants are absolutely fascinating creatures. Not only have they discovered farming and animal husbandry thousands of years before us (sometimes even using bacteria to grow gardens), they also conduct executions for the good of the colony, follow Fermat’s principle of least time, and as it has been shown now, draft parasite ants as mercenaries. Just […]
A cross-disciplinary team of scientists at Harvard that developed a novel type of vaccine for treating melanoma – the most lethal form of skin cance – recently announced the vaccine will enter its Phase 1 clinical trial. The announcement comes just a few years after the vaccine was tested on mice, 50% of whom showed […]
Founder of Paypal, Tesla Motors and SpaceX, Elon Musk has gained the reputation of a brilliant entrepreneur and engineer. By many he’s viewed as a real life Tony Stark, a comic book and, most recently, Hollywood blockbuster character better known by his Iron Man persona. Musk in many respects, in my humble opinion at least, […]
Henry Ford’s Model T automobile changed not only the way the average American traveled (the first trully affordable vehicle for the middle class), but the way industry in all its forms viewed production. By switching from hand craft to the assembly line, Ford drastically cut cost and speed of production of his automobiles, a model […]
Since touch screen interfaces have been introduced on mass scale the way people interact with technology has been arguably revolutionized. Still, there is much more to be explored in how the sense of touch can be manipulated to enrich user interaction with tech. Recording and relaying back information pertaining to the sense of sound (audio […]
We all know that CO2 dumped in the atmosphere (consequences in the ocean, where the most carbon winds up actually are even dire – i.e. ocean acidification) causes global warming through what’s commonly referred to as the greenhouse gas effect. Governments and various environmental panels have through out the years issued various policies meant on […]
Since the study of modern chemistry was initiated, only 36 basic types of chemical reactions have been fully described. Recently, researchers at MIT, building on the work of another study published 30 years ago, have fully described the mechanisms of a 37th reaction – a low-temperature oxidation that results in the decomposition of complex organic molecules […]
It’s amazing how two different animals from two completely different environments evolve some identical physical features. Take bats and dolphins for instance. Both of them use a complex system that produces, receives and process ultrasonic sound waves in order to identify visually hidden objects, track down prey or navigate through obstacles better – typically this […]
In 2010, 4,280 pedestrians were killed in traffic crashes in the United States, and another 70,000 pedestrians were injured. Various solutions have been applied in the past to reduce pedestrian traffic crashes, from smarter traffic lights, to improved pedestrian crossing design. The most extreme proposed solution so far, however, comes from Honda. The Japanese car […]
=Poverty posses long-lasting social, emotional and, least not forget, cognitive perils. A recent study found that people under financial strain have a hard time focusing on anything else other than their day-to-day strides, seriously affecting their cognitive abilities. The researchers, led by noted Harvard economist Sendhil Mullainathan, found that people affected by poverty scored as much […]
It’s a lazy dog owner’s dream come true. What if you had a remote control that you could use to instruct your dog to perform various household tasks, like say… grab you a cold one from the fridge? Scientists at Auburn University, Alabama have devised a system that makes such a thing possible, although the long […]
A recent study has revived an older controversy, after Dartmouth Professor Mukul Sharma and his team reported what they claim is the first conclusive evidence that links an extraterrestrial impact in Canada with the beginning of the Younger Dryas, a period of abrupt climate change that caused major cooling through the Earth. During this time, a number of species became […]
Say hello to drop-proof smartphones and whole new generation of plastic products that will be far more durable and strong than their present counterparts.

MIT and Chilean researchers working together have developed a fog harvesting system which can provide drinkable water for even the world’s driest regions. In the full drought areas, where rainfall is extremely rare or virtually non existent, a few specialized plants and insects have devised ingenious strategies to cope with the harsh conditions and get […]
In a breakthrough moment, researchers at Harvard School of Engineering and Applied Sciences have developed a novel material resembling a simple transparent disk, which the researchers applied an electrical signal to and used it to play music. This is no ordinary speaker, though. The disk consists of a thin sheet of rubber sandwiched between two layers of […]
A common and favored method of execution in ages long past, decapitation is one of the cruelest and frightening human practices. Its employment sends a powerful message of punishment and seeing how its been used for thousands of years, it’s been most effective. There are numerous accounts and stories of how some decapitated heads still […]
Scientists have discovered an atypical gene that is thought to be crucial for the generation of new neurons in the brain, a process called neurogenesis. The discovery and further study of the gene might help scientists better understand how neurodegenerative diseases such as Alzheimer’s affect the brain and, in term, how to address them. New […]
For nearly two years now, Syria has been embroiled in a gruesome civil war that has so far claimed thousands of lives. Cruelties in the region reached a climax in past weeks after alleged reports of chemical weapons use against civilians were made. So far, it’s unclear which side – the government or rebelling opposition […]
Regenerative medicine has come a long way, and while important strides forward have been made, scientists are still toiling with ways to completely grow organs in labs. There are millions of people worldwide suffering from afflictions to organs like the liver, lungs or heart – for many of them a transplant is they’re only chance […]
It’s clear that humans are now, more than ever, a driving force in evolutionary biology. Early domestication efforts through breeding and training have changed some species to the point that they’ve grown to be as we wanted them to become. The effects of climate change, a great part of which is anthropogenic, actually influence animals […]
Time and time again we’ve hailed on ZME Science the cultural and scientific advances graphene is about to bring to humanity. It’s the strongest material known so far, while also being the lightest, it can be magnetic and – something of uttermost important to science – it’s the best electrical conductor that we know of. […]
When the space shuttle was first designed, its makers intended on building the very first partially reusable craft capable of sending cargo or people into space and then return. The vision was extremely seducing: you launch the craft and then within a few days it would be ready to fly again, greatly reducing cost and […]
Researchers at the Norwegian University of Science and Technology’s (NTNU) Department of Neuroscience analyzed a massive survey of 130,000 randomly chosen people from the US to see whether there is any association between psychedelic drug use and mental health problems – a claim that has had large circulation and is often cited, despite little research in […]
Our bodies are hosts to some hundreds of thousands of bacteria that live in harmony with each other, helping the body be healthy, in return for the food and shelter it provides to these tiny organisms . Collectively, all the microorganisms inside the human body are referred to as the microbiome, most of whom are […]
Conodonts – Greek for “having cone-shaped teeth” – are extinct chordates resembling eels, classified in the class Conodonta. These are some of the most primitive vertebrates in recorded fossil history, and are of particular interest to scientists because of their toothlike structures that lend the group its name. For a while it had been unclear how […]
The general belief surrounding black holes is that they’re massive, but vicious matter gobbling cosmic objects. While it’s true the reputation of black holes as destroyers precede them, we should not forget that they fill an important role in the Universe as creators. Scientists now know that black holes are inexorably linked with galaxies, lying […]
Some 300 million cases of malaria are reported each year in Africa, the continent where the disease is still running rampant. For decades, scientists have been investing immense amounts of energy battling the disease, trying to come up with effective treatments. The recent step forward in the war against malaria comes from Maryland-based biotech Sanaria, which […]
Dr. Sanjay Gupta is an established neurosurgeon, but you all might know him better as CNN’s chief medical correspondent through the various live interventions he’s had along the years on television as well as some feature documentaries. Last night, his most recent documentary, called “WEED”, premiered on CNN as you might have already guessed, it’s all […]
For many quantum mechanics is very hard to comprehend because so many of its insights are extremely bizarre (see spooky action at a distance or quantum entanglement) and counter-intuitive (for instance wave-particle duality, which is the idea that all things have both a wave- and particle-like nature). For many years scientists vacuum was synonymous with […]
As solar cells, and obviously the solar energy sector in consequence, become ever more popular spurred by increased demand through out the world, scientists today are currently interested in two major keypoints: increasing efficiency – the most important and immediate goal at hand – and making solar cells as cheap as possible without, obviously, compromising […]
Using an innovative technique that mathematically infers what the environment outside the lens’ perspective might look like based on how light enters the camera, researchers at Harvard University have managed to create 3D images using only one lens and without moving the camera. The findings could prove to be applicable to amateur and professional photographers […]
The Argus II is the first bionic eye implant, designed to grant the blind vision, that has been approved by the FDA in the US. The wearer of such an implant is now capable of distinguishing objects and live an almost independent life, which is absolutely remarkable by itself, however its performance is light years […]
Temperature is an important physical parameter which greatly influences a system. Monitoring and/or manipulating this state parameter with great accuracy is thus of great importance to scientists. Recently, researchers part of DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program proved a new technique that allowed them to measure and control temperatures at the nanometer scale inside living cells. Measuring […]
Mona Lisa is probably the most well known picture in the world – it’s been painted thousands of times, inspired countless artists, and her enigmatic smile still puzzles researchers and artists alike; but never before has it been painted on such a small canvas. Demonstrating a very potent nanotechnique, researchers have made a miniature Mona Lisa […]
It may not look like much, but this material has wonderous properties, according to Swedish researchers. The magnesium carbonate is extremely porous, setting new records in terms of surface area and water absorbtion, potentially having all sorts of applications, from controlling moisture in electronic and medical procedures to gathering up pollutants from oil spills. Still, the practical, […]
Dolphins are simply stunning creatures – they think, and empathize; they have names, hang out in cliques, they talk like humans, and they almost always try to rescue their wounded friends. They can go without sleep for 15 days, and every day they show us that they are simply ‘non human persons’. Now, another research […]
The waves of controversy and outrage following former CIA and NSA technical officer Edward Snowden’s leaks of details that reveal the US and British governments had been secretly deploying mass surveillance programs on their citizens are far from over.
