This weekend, one of the most curious and utopian conferences took place in New York City, where some of the brightest minds in the field of neuroscience, biotechnology and robotics gathered to discuss the prospect of transferring the human brain and mind out of the biological body and into an artificial vessel. As oddball and […]
It’s rather clear that social-economic factors have a huge part to play in the development of an individual, but when discussing this we typically refer to education, something that can be more or less manipulated at any time, albeit with various degrees of difficulty. How do social-economic aspects affect the brain, though? Martha Farah, the founding director […]
Is there something that graphene can’t do? It’s the world’s strongest material, even when it has flaws, a graphene aerogel is also the lightest material known, it’s great for sensors, for headphones, it repairs itself, and boasts a swarm of other features and capabilities. Now, researchers from Manchester University have shown that they can create […]
Located in the North Atlantic, right in between Greenland and Scotland, Faroe Islands is one of the smallest countries in the world. At the same time, however, it has also remained fairly isolated for many centuries, which in time has led to the formation of a distinct language and population. You can spot a native […]
The Japanese freshwater eel (Anguilla japonica) is a popular choice on any sushi menu, but recent findings reveal that there’s more to it than just a simple snack. Biologists have identified a special fluorescent protein – the very first case found in a vertebrate – that makes the eel naturally glow in a bright green when […]
Scientists at The University of Nottingham have come across what can be a monumental discovery, demonstrating for the first time a new layer of the human cornea. The layer, which was described in a paper in Ophthalmology, could help surgeons to dramatically improve outcomes for patients with severe cornea affections and those undergoing surgery. The […]
More and more discoveries seem to hint at a watery past for Mars. Now, NASA research shows that hunks of frozen carbon dioxide (dry ice) may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing away as they go down. This study could explain one of the mysteries of […]
Typically on Earth, days usually have a temperature maximum somewhere after lunch, and a minimum during the night. But for Mars, things are pretty different: “We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight,” said Armin Kleinboehl of NASA’s Jet Propulsion Laboratory […]
For more and more people, ageing and clumsiness seem to go hand in hand – difficulties when handling a plate, fumbling with keys or even dialing a phone – new research from Washington University in St. Louis suggests that some of these day-to-day reaching-and-grasping difficulties may be be caused by changes in the mental frame […]
Mind-controlled devices, also known as brain-computer interfaces, have evolved a lot in the past few years alone, offering countless people who are paralyzed or missing limbs the chance of living a normal life. Non-afflicted individuals may profit from brain-computer interfaces as well, either for fun (why bother with gamepads or even Kinect when you can […]
You may have heard about the Tunguska event – a huge blast of energy which occurred in 1908 over Russia and flattened more than 2,000 square kilometres of forest. More than a century since, its remarkable that scientists have yet to confirm the source of what undoubtedly is the biggest Earth impact in recorded history. The leading […]
As reported earlier on ZME, as little as three thousand tigers are currently alive today in the wild from six subspecies, or thirty times fewer than 100 years ago. Loss of habitat and poaching are the main drivers that brought these majestic cats at the brink of extinction. Now, a new threat might put tigers […]
An extremely rare and small galaxy has just been reported by astronomers, which by all accounts can be considered the least massive galaxy discovered thus far. The very faint galaxy, consisting of roughly 1,000 stars, supports current theories relating to the formation of the Universe. Located in the constellation Aries, the dwarf galaxy dubbed Segue 2 […]
Most certainly, one of the top goals in physics today is proving the existence of dark matter – the elusive form of matter that makes up 85% of all matter in the Universe. Many theories have been proposed and tested, however to this day we only have glimpses and possible hints of dark matter. A […]
The first known case of a bone tumor has been discovered in a Neanderthal who lived about 120,000 years ago in what is now present-day Croatia. The bone samples come from the already famous cave/archaeological site Krapina, which now hosts a Neanderthal Museum. Bone tumors are exceptionally rare finds in fossils and archaeological records, with […]
A new visualization technique developed by researchers at the Howard Hughes Medical Institute used a thin sheet of laser light that beams, stepwise, into different planes of a specimen to create intricate and detailed snapshots of cells. In these pictures featured above and below you can see how zebrafish and fruit fly embryos were imaged using this novel […]
Living fossils, fast adapters Sturgeons have been conserved as fossils ever since the early Cretaceous – some 130 million years ago; they are what we call ‘living fossils’. But a new study by University of Michigan researchers revealed that in some aspects, sturgeons are one of the fastest-evolving fish on the planet. “Sturgeon are thought […]
Our general appearance and dominating facial features have come a long way since the days of our early homo sapiens ancestors some hundreds of thousands of years ago. For instance the size of our brain, and of course skull that houses it, has grown in size three times since then. Moreover, medical records only a […]
It’s not a well known problem by most, but those who work in the field are very aware of it – medical isotopes are a very valuable commodity. But now, a Canadian team may have very well found a way to end the shortage, developing and upgrade that allows hospital cyclotrons to make a much-needed […]
If you’ve ever visited a cave, you probably know the golden rules: Watch you’re head, stay on the track, and keep your grase paws off the formations! Why the last one? Well, because the hands and dirt you have on your hands can impede their growth. But when you go inside a cave as a […]
Early galaxies were very different from those we see today – it was overgrown black holes, and not stars that lit them up, claims a new study; in it, it is suggested that these obese black holes were numerous and bright enough that we should be able to detect them now, billions of years […]
Psychologists closely studying chimpanzee, bonobo and human infants found striking similarities among the three species in terms of different types of gestures. Their findings seem to back-up the theory that claims language, as we know it, evolved from gesture-based communication first. Panpanzee, a female chimpanzee (Pan troglodytes), and Panbanisha, a female bonobo (Pan paniscus) were […]
Invisibility cloaks have become the object of study for many research institutes out of a number of considerations. There’s the simple scientific thrill of breaching the SciFi barrier, something every researcher dreams of. Then of course, there’s always the corporate and military tail that always likes to meddle with concepts that shine with the possibility […]
The case of birds missing out on a proper penis has been a longstanding mystery in evolutionary biology. Roughly 97% of avian species sport little or nothing like a real phallus, yet they still reproduce via internal fertilization. A new study, conducted by Martin Cohn, a developmental biologist at the University of Florida in Gainesville […]
At 55 million years old, it represents the earliest known member of this broad group of animals that includes humans. It may be no bigger than a mouse, but it is a primate, and a very valuable one at that; paleontologists have named it Archicebus, which roughly translates as “ancient monkey”. The team which described […]
As bad as earthquakes can be, and we’ve recently had our fair share of earthquakes around the world, the tsunamis they generate can be even worse. When an earthquake has a significant effect in a body of water, it displaces large quantities of water – and it is that displacement which causes the huge waves […]
The French didn’t invent wine, no more than Colombians invented coffee or the Italians discovered tomatoes. But… who did? What is the actual homeland of this wonderful drink? After analyzing some limestone residue, archaeologists working at University of Pennsylvania claims to have found the earliest evidence of European winemaking. The 2,400-year-old stone is apparently a […]
Hydrogen is the most common element in the Universe. It’s the first element in the periodic table, and it has but one proton and one electron. Understanding how it behaves at very large pressures is crucial to our understanding of matter and the nature of hydrogen-rich planets. Under typical conditions, Hydrogen is a diatomic molecule […]
Just yesterday we were telling you about a change in diet 3.5 million years ago, modifying the way our hominid ancestors evolved and, in turn, how we evolved. Now, we’re moving a little closer to the present day – researchers calculating the barium levels in fossil teeth claim that they’ve found a difference in the […]
In a quest to make concrete not only more durable but also more sustainable, a group of geologists and engineers have found inspiration in the ancient Romans – whose imposing buildings have passed the test of time, surviving two millennia. Geology and the Romans Using classic microscopy, as well as the Advanced Light Source at […]
Scientists at the Rehabilitation Institute of Chicago (RIC) demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR), part of DARPA’s Reliable Neural-Interface Technology (RE-NET) research program which seeks to develop effective brain interfaces. The prosthetic is simply amazing, as one can see in the video below featuring former Army Staff Sgt. Glen Lehman, injured in Iraq. The […]
A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles, similar in many ways to a fundamental particle postulated by Paul Dirac in 1931. Monopoles and Dipoles Until now, a magnetic monopole, the magnetic analogue to an electric charge has never been observed – all we had until now […]
To fully understand the processes and mechanisms that work at a cellular level, biologists should study them in their native, watery environments. But how would you go on doing this? Well, leave it to engineers to solve everyone’s problems – they have now deviced a kind of atomic force microscopy that works on samples sitting […]
One big obstacle scientists face in their efforts to develop effective drugs against HIV is the virus’ capsid – an outer cell membrane-derived envelope and an inner viral protein shell that protects HIV essential proteins and genetic information. Current drugs have a hard time breaching this structure, however this might change. Using a supercomputer that crunched immense […]
It seems like every week there’s a new study that hails a new wonder property or fantastic application for graphene. Is it truly the material of the future that will catapult technology to the next level? Seems like it. For instance, scientists at Nanyang Technological University (NTU) in Singapore used graphene as the basis for a novel […]
New analysis of fossil teeth from extinct fossils has shown that human ancestors greatly expanded their diets 3.5 million years ago, moving on to eat grasses and also other animals. Before this, the humanlike creatures (hominis) ate a forest based diet, pretty similar to what chimps and apes eat today. Researchers from the California Academy […]
Despite the fact that triceratops are some of the most well known dinosaurs, finding a complete skeletons is an extremely rare treat. It was one of the last non-avian dinosaur genera to appear before the Cretaceous–Paleogene extinction event – the extinction which caused the end of dinosaurs and the Mesozoic. The scientists from the Black […]
The only two (significant) places in our solar system, that we know of, which can create opals are Central Australia and Mars, so by studying the geologic processes which led to the creation of these minerals in the first place, we can perhaps find out more about the Red Planet. As a geologist, I was […]
We’ve written a great deal about schizophrenia in the past, mostly reports about new theories pertaining to the development of the disease or new types of pharmacological treatments. A great deal of interest and efforts are being invested in battling this severe psychological disorder, since it affects so many people (as many as 1 in […]
Researchers have for the first time described an unique snail species that can only be found high on top Mount Kaputar in New South Wales, Australia. The snails exhibit an atypical coloring – fluorescent pink – and can grow as large as eight inches long, true giants by snail standards. Though Triboniophorus aff. graeffei […]
In terms of materials, graphene is definitely the hot cherry at the moment; it is basically a one-atom thick layer of the mineral graphite (carbon), with more such layers stacked together forming crystalline graphene. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams, but also very durable and has a number of […]
“Eat, drink, and be merry for tomorrow we die” – seems to be the motto at big oil companies. At Wednesday’s meeting for ExxonMobil shareholders in Dallas, CEO Rex Tillerson told participants that the economy is currently relying on oil, and that will not change anytime soon. He concluded that cutting down on carbon emissions […]
Every living being is important, however in a transnational-based society everything has a price label on it, even humans. A recent study, for instance, has assessed the economic value of sharks, both alive and dead. The researchers involved in the study found that shark ecotourism currently generates more than US$314 million annually worldwide and is expected […]
The Brazilian rain forest is a home to a slew of birds of all shapes, sizes and coloring – some 1,700 species to be more precise. One of such bird is the goofy looking toucan, which can be easily recognized by its extremely long beak which can reach half the size of the bird’s body. Human […]
Turtles are maybe the most majestic creatures in the reptile world, and have always been a source of inspiration for man. Everybody knows the fable of the turtle and the hare, which teaches how slow, but sturdy and resilient strides can outwit inconsistent sprints. The turtle’s really serious about it, and as evidence it practices […]
Detailed analysis and review have confirmed the scientists’ initial opinion – the pebble containing slabs Curiosity stumbled upon last year were indeed part of an ancient streambed. When the Curiosity rover landed on Mars, it was expecting to find lots of things – but finding evidence of ancient water so close to the land site […]
NASA’s GRAIL mission had been studying the Moon’s gravitational field for 9 months, with great results – they have discovered the massive regions which cause irregularities in the Moon’s gravitational field, making it uneven. Planetary gravitational fields The Earth, the Moon, and pretty much all planets have irregular gravitational field – first of all because […]
Black holes are the single most interesting and puzzling objects in our Universe – that we know of. But as if they weren’t mysterious enough, researchers have found that if you apply a quantum theory of gravity to these bizarre objects, the all-crushing singularity at their core disappears, opening a whole new Universe of possibilities […]
Over the past decades, what we mean by glue has changed significantly; techniques have emerged, materials have been developed, and one of the most viable candidates for a superglue is gold. Researchers have found numerous applications for attaching molecules to gold; the approach uses chemicals called thiols to bind the materials together. But while this […]
In a never-before seen feat, astronomers using NASA’s Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, something which can provide valuable clues to understanding these mysterious objects. Neutron stars Neutron stars are the cores of former high-mass stars, the remains of supernovae after the blow-up. As the core of the massive […]
