We’ve already written novels on how much 3D printing has evolved and what magnificent things we can accomplish through it: from printing bacteria to printing baroc rooms, from saving babies’ lives to rocket engines and from ears and cartilages to nanoscale objects, 3D printing promises to revolutionize the world we live in. Now, the European […]
It was a result so unexpected that MIT researchers first thought there was some kind of mistake – under certain conditions, putting a cracked piece of metal under tension (pulling it apart) has the reverse effect – causing the edge of the cracks to fuse together. The surprising, counterintuitive find paves the way towards self […]
How do organs such as the heart or kidneys know when to stop growing? A number of theories have been proposed to answer this, the most entrenched of which dating back from 1952, when the infamous Alan Turing used math to show how biological cell patterns form and how these knew when to stop division. Turing […]
Drinking until the early hours of dawn may be exhilarating for some, however the next day everything seems to tumble over as the mind is assaulted by a barrage of hangover attacks. There are a number of popular home-brewed remedies against hangover: eating eggs, sipping a bit of castor oil, Vitamin B effervescent pills, tomato […]
A joint project between scientists at NASA and MIT is focusing on creating a new kind of microscope that uses neutrons instead of beams of light or electrons to create high-resolution images. Since the subatomic particles are electrically neutral, such a microscope would allow scientists to peer through places otherwise inaccessible today, like inside metals […]
Using ultrasound radiation, researchers at University of Bristol (UK) have devised a computer interface that basically allows users to interact with a digital screen without touching it. Sure the Kinect or Leap Motion does this already, the catch is that this system also provides haptic (touch) feedback. So, whenever a user traces a motion in […]
Yesterday was Neil deGrasse Tyson’s 55th birthday, an astrophysicist, director of the Hayden Planetarium, and popularizer of science. Nearly two years ago, during one of his Ask Me Anything’s on reddit, deGrasse Tyson answered one of the questions posed there by a fellow redditor asking “Which books should be read by every single intelligent person on […]
In theory, the philosophy regarding the value of a human life is rather straightforward: all human life should be treated equally and offered equal rights. Now, in practice this doesn’t necessarily happen. We all have prejudice, we all are afflicted by bias and in case of a dire situation, most people would first try to […]
A rare sight to behold, the elusive Pinocchio lizard was finally spotted after a team of researchers and photographers set on a long quest to find it. Their efforts were rewarded as this is only the third time a specimen of this long-nosed lizard was ever reported in nearly the 60 years since its discovery. […]
Mere hours after his death in 1955, Albert Einstein‘s brain was removed, weighed and analyzed in a lab at Princeton Hospital by pathologist Thomas Stoltz Harvey. Bits of his brains were then sent to other pathologists around the country for analysis in hope that a connection between its physical attributes and the remarkable genius of […]
A common assumption in human evolution is that our early ancestors first developed bipedal locomotion and only then did they developed dexterous hands capable of using tools, since these were free to be used no longer being required for walking. A new research by a team of Japanese scientists proved this long-standing assumption wrong, however, […]
Physicists have been dreaming of achieving controlled nuclear fusion for decades, and year by year we’ve been getting closer to turning it into reality. A recent paper published in the journal Physics of Plasmas reports improvements in the design of an experimental set-up capable of igniting a self-sustained fusion reaction with high yields of energy. Researchers at […]
Researchers at the Chinese University of Hong Kong have developed a new type of microbots approximately the size of a human cell that can carry more targeted drugs than other such options. These can be guided wirelessly through magnetic field manipulation. The Chinese designed microbots as well as other micro or nano-scale alternatives are meant to […]
A team of brilliant researchers at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have demonstrated a working particle accelerator, used to accelerate particles like electrons or protons to extremely high energies and probe the Universe’s secrets, which is the size of a typical silicon chip. Typically, particle accelerators range from a […]
After they identified precise groups of cells in mice brain that induce eating and others that curb it, a team of researchers caused full mice to continue eating and hungry mice to stop eating simply by stimulating one of these areas. Their findings could aid in the development of novel drugs that target eating disorders […]
In a mind boggling act, spiders are capable of “ballooning” themselves using silk strands and fly for miles, both in altitude and distance. Small and big spiders alike can do this, although smaller ones are capable of traveling further, and scientists have long theorized the mechanisms of spider ‘flight’. Peter Gorham at the University of […]
Death is ubiquitous and inevitable, and people have learned to cope with it in various ways. In some places of the world, however, death is a more immediate prospect than in others. A team of researchers at Michigan State University led by marketing professor Ayalla Ruvio found that people faced with a mortal threat such as a […]
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. Scientists at Duke University recently unveiled their most recent, stunning work: a new type of polymer that seems to contradict common knowledge and re-arranges its chemical structure each time its under […]
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 […]
