In a fantastic discovery, a team of archaeologists have dated a pair of footprints preserved in the mineral-rich sediment in the Chihuahuan Desert to find that these are 10,500 years old. These are the oldest human footprints discovered thus far in North America, predating any previous find by some 5,000 years. Moreover, the footprints mark for […]
We’ve written extensively about the impending global disaster triggered by the crippling of bee populations worldwide at the hand of Colony Collapse Disorder (CCD). Just recently, I wrote an article discussing the findings of a new paper that suggests the leading factors that cause CCD are most complex than previously thought – namely, a whole brew […]
Fractals are non-regular geometric shapes that have the same degree of non-regularity on all scales. Fractals are the kind of shapes we see in nature, basically, and even though the term was first coined only a coupled of decades ago or if this is the first time you’ve heard about fractals, chances have it that you […]
Over the past six years, and estimated 10 million beehives have been wiped out as a result of the so-called Colony Collapse Disorder (CCD), causing damage worth $2 billion. It’s difficult to put a price tag on billions of bees, though, or the actual damage their collapse is causing. As you may know, bees pollinate […]
The most common grade at Harvard is A, and the median grade is A-, Dean of Undergraduate Education Jay M. Harris explained, raising fears about top American Universities artificially inflating their grades or employing softer grading standards. The information was delivered at the monthly meeting of the Faculty of Arts and Sciences, as a response […]
We’ve written extensively before about the life harboring possibilities of Jupiter’s moon, the icy Europa. The moon is believed to be the likeliest candidate in our solar system, besides our own planet, capable of supporting life. Recently, a report compiled by researchers at University of Texas at Austin, the Georgia Institute of Technology, and the Max […]
As more and more research is conducted on Neanderthals, we start to understand that we’re not as unique as we thought, and that they were equals or even superior in many ways. Now, researchers have found that Neanderthals organized their living spaces in ways that would be familiar to modern humans. The findings show that […]
The recent discovery of DNA of a 400,000-year-old human thigh bone could provide valuable insight into the evolution of humans; researchers explain this is easily the oldest human genetic material ever found. When it comes to being a mountain, the Atapuerca Mountains in Spain don’t really have much going for them. It’s an ancient karstic region […]
Writing your memoirs or simply recollecting traumatizing memories in writing has been used as tool in therapy for many years now. A new study by researchers at University of Iowa found that switching to writing in third person eases recovery and improves health of participants. Whether it’s a car accident, the death of someone close, surgery, […]
Humans and the food chain A country-by-country study has shown that the fast-growing economies of India and China are riving a global increase in meat consumption, cancelling out decreases elsewhere. This has serious negative environmental implications. The work analyzed both what people eat, as well as the trends of what they are eating. They also […]
Generally, you can view services like any other commodity and apply strict goods economics. So if the same type of service is available elsewhere, even in another country, at a cheaper price it makes sense, economically, to outsource. Is health care a different matter, however? Apparently, if you took an X-ray in the past decade, […]
North Carolina State University researchers report that parents who work odd schedules or jobs that differ from the typical “9 to 5” schedule risk deteriorating the relationship they have with their children. In some instances, however, the researchers found that certain work odd schedules help form better child-parent relationships than a 9 to 5. An […]
A new report made by a team of Harvard researchers proposes a set of measures aimed at leveling the health ground in the world by 2035. The authors envision a grand convergence, namely closing the most egregious equity gaps we still have between poor and rich populations around the world. Isn’t offering the same health benefits […]
Drug resistant bacteria (immune to almost all antibiotics) are dreaded by patients and physicians alike. Finding them in hospitals is bad enough as it is, but failing to detect them is even worse – it can result in a dramatic outbreak. This is why patients with bacterial infections are typically screened using automated lab tests […]
In transportation, there aren’t that many alternative energy sources like in conventional industry, where you can supply a plant or even a home using solar, hydro or wind power. Before electric vehicles make a significant contribution (don’t hold your breath for too long), alternative means of fueling engines need to be found. This is why […]
Using the Hubble telescope, astronomers have identified faint signals of water in the atmosphere of five exoplanets. The alien planets, however, are classed as hot-Jupiters – huge planets with a surface temperature too hot to support life. Finding water on planets light years away from Earth is definitely of great note and marks a step […]
It’s surprising to me that this has to be said, but … oh well. If you are obese, you’re unhealthy. Even if you have normal blood pressure, cholesterol and blood-sugar, you’re still unhealthy. A study, published in the Annals of Internal Medicine, concluded that so-called “healthy obesity” was a myth. “Healthy obesity” or “benign obesity” […]
The United States is spewing 50 percent more methane than the official federal government estimates, a new study concludes. The paper, which was published in the Proceedings of the National Academy of Science shows that most of the emissions come from cows, refineries and drilling spew and occurs in Texas, Oklahoma and Kansas. This not […]
Volcanoes aren’t generally regarded as being particularly practical for us humans, quite frankly on the contrary. An innovative company from Iceland, however, is suggesting that it may be feasible to produce methanol – a liquid fuel with high heating value that can even work with normal gasoline-powered engines – by refining the CO2 spewed by […]
One of the predictions derived from Einsten’s theory of general relativity is the existence of wormholes – spacetime shortcuts. In theory such bridges may offer instantaneous travel between the two bridgeheads or wormholes even if these are light-years away from each other. Two independent studies suggest that there’s a link between quantum entanglement and wormholes, […]
In the early hours of December 2nd, China deployed its Chang’e-3 spacecraft on route for the moon after launching it via a Long March 3B rocket from the Xichang launch centre in Sichuan. The spacecraft is expected to reach lunar orbit in about 4 days, if everything goes as planned. On 14 December, the probe is expected to touch […]
The pitch of male koalas’ mating calls is about 20 times lower than it should be, judging by their size and anatomical features. Now, researchers found that a unique sound producing organ, unlike anything found in other mammals, is responsible for this strange pitch. “We have discovered that koalas possess an extra pair of vocal […]
Male birth control pills have been researched for some time, however previous attempts have been found to be ineffective. A new method that concentrates at blocking male sperm ejaculation, has been found to be effective in mice. A drug could be administered orally, just like the female version. Before a male birth control pill can […]
Brigham Young University (BYU) engineers have teamed up with one of the world’s leading experts in origami to solve one of space exploration’s most challenging (and ironic) problems – the lack of space. Working with NASA’s Jet Propulsion Laboratory, a team of mechanical engineers have designed a solar array that can be tightly compacted for […]
It’s been previously shown that the jellyfish are the world’s most efficient swimmers, and researchers wanted to see if they could implement some of its features into a flying machine. New York University researchers have built a small vehicle whose flying motion resembles the movements of a jellyfish – possibly paving the way for small […]
Two distinct groups of crocodilians have been reported to use tools for hunting They balance sticks on their snouts, baiting birds who want to use the sticks for nests Crocodiles actively search for the sticks (which are usually rare) and do this more often during the birds’ mating season It’s been known for quite a […]
A new study which involved the analysis of over 1.000 brain scans confirmed what many intuitively believed for a long time: men and women’s brains are hard wired differently. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, while men had better connections between the […]
Biotechnology is growing fast and the findings researchers are making the field are nothing short of breathtaking. Previously, ZME Science reported in the past few years alone a series of milestone premiers: the first bioengineered kidney and 3-D human kidney cells, the first functioning blood vessels, the first teeth-like structures, a bioengineered heart that beats on its […]
Drug delivery encapsulated in tiny nanoparticles are thoroughly studied with great interest because they offer the chance to deliver treatments more efficiently. That’s not all though – with nanoparticle pills you can selectively target key areas and deliver drugs which otherwise wouldn’t be possible without using invasive methods. Take diabetes for instance – patients need […]
Generosity and fairness As shoppers all around got more or less advantageous deals on Black Friday, researchers at the University of Berkeley are analyzing what happens to commerce and buyers when there’s no fixed price tag – when shoppers pay as much as they want for products. As it turns out, they spend more money when […]
Your gut is home to some 100 trillion bacteria – more than the entire number of cells in the whole human body. Clearly, bacteria are fond of human intestines, as we humans, unknowingly or not, are fond of them. After all, without bacteria our organisms would be deprived of extremely vital vitamin sources and digestion […]
Schools in the US are failing on teaching children civic involvement Simply learning facts about democracy (for example) is not nearly enough Educators should get their hands dirty and focus more on controversial issues More and more researchers, teachers and educators are starting to support the idea of a major revolution in […]
Google Glass is a hands-free technology, with potential applications in a myriad of fields Surgeons have recently started performing surgeries with Google Glass They report great results, as this technology can save a lot of time and effort Google Glass seems like the technology of Star Trek – except it’s here, now. For those who […]
Ever found yourself in a hazardous relationship in which your spouse makes your hair go white? Well, if the answer’s yes then you’re not alone. A new study provides new evidence that key aspects of the social environment of some animals significantly influence life span after researchers found that sexually frustrated fruit flies and “haunted” […]
Trying to better understand how memories are stored inside a human brain, researchers from the University of Pennsylvania and Freiburg University used a video game in which people navigate through a virtual town delivering objects to specific locations; they found that brain cells add a geo-tag with spatial information to some memories, and this spacial […]
Apparently, there’s no limit to what you can develop via 3D printing. Researchers at the University of Liverpool are currently working towards developing synthetic skin that can be produced on a 3D printer and matched to a person based on their age, gender and ethnic group. 3D printing may be in its very early stages, […]
Photons and molecules Scientists managed to ‘trick’ photons (the elementary particles of light and all other forms of electromagnetic radiation) into forming molecules for the first time – a state of matter that until recently had been purely theoretical. Scientists from Harvard University and the Massachusetts Institute of Technology (MIT) are challenging the current paradigm […]
Carbon nanotubes and graphene have been hailed time and again as the wonder materials that will change the face of technology in the future. Before silicon can be dethroned from its reigning position, however, a lot of manufacturing issues need to be addressed. A new technique developed by researchers at University of Illinois provides a […]
The wonder material Graphene, the new wonder material that promises to open a new age in technology, just got a whole lot better. Researchers have reported improved interfacing of graphene with other 2-D materials – basically ‘growing’ graphene on silver. This resulted in an exceptionally pristine sample, presenting opportunities for ultrafast electronics and advanced optics/ […]
UPDATE: Telescopes saw the giant ball of ice and dust disappear behind the star, but then fail to emerge as expected. ISON is dead and gone, folks. Sorry. The ISON comet, a giant icy cosmic body from deep space, may just become the most spectacular comet ever – if it lives past today’s Thanksgiving that is. […]
Invasive (or alien species) are non-indigenous species that adversely affect the habitats they invade China currently has 550 invasive species, which cause losses of $15 billion yearly This affects the entire world, as China is the main exporter, and invasive species often piggyback exported goods Alien species When China opened its borders to international trade, […]
Mice in the control group refused to drink alcohol When a certain gene was deactivated, they started preferring alcohol over water Researchers stress that human alcoholism depends much more on environmental and personal factors Researchers have discovered a gene that regulates alcohol consumption; when this genes becomes faulty, it makes humans more prone to […]
Japanese researchers showed that cats are able to recognize their owners’ voices from other voices, but because they domesticated themselves, they never really needed to take notice. The study supports the idea that while cats are often kept as pets, they are beholden to no one. Reserchers Atsuko Saito and Kazutaka Shinozuka tested twenty housecats […]
The Permian extinction was the biggest extinction ever, killing 96% of all marine species and 70% of terrestrial vertebrates Possible causes include: impact, loss of oxygen and volcanic eruptions Researchers tested the validity of the last hypothesis, finding it likely The biggest extinction – ever MIT Researchers believe that rain as acidic as undiluted lemon […]
Chernobyl is still one of the most radioactive places on the face of the Earth, and authorities are working on a huge program to reduce any further risks of contamination. Work began in recent days to remove, bit by bit, the giant chimney protruding from the Chernobyl nuclear power station. The Chernobyl disaster was a […]
Norway’s Magnus Carlsen and India’s Viswanathan Anand are duking it out in the world championship, apparently, without anyone else contesting their supremacy. But as insanely good as they are, they still can’t stand up to the best computers today. As a matter of fact, there is one theory which, if proven, could pretty much spoil […]
The Bonobo, or Pygmy Chimpanzee as it was once called, is one of our closest relatives, yet one of the most poorly studied. This fascinating ape displays unique social order and other highly interesting traits, and unfortunately like all great apes it is also endangered. Very little is known, however, about how many specimens are […]
Previously, it’s been shown that obesity can cause changes in the brain, leading some people to over eat food high in saturated fat and refined sugar, as well as cause poorer memory. A new study published by researchers at University at Buffalo found a new physiological trait that can become altered as a result of obesity. […]
Despite all the related problems which contribute to obesity such as stress , the main cause is… eating too much. Recent studies have shown that people tend to overeat when they are stressed out – often creating a negative cycle of eating more, gaining weight and then getting stressed out about gaining weight – especially […]
Seahorses are some of the most awful swimmers, but they’re still very efficient hunters. 90% of their hunt attempts are successful, compared to the lion’s 25% and the shark’s 50%. Their snouts are shaped to minimize water disturbances, allowing them to creep up on their prey. Seahorses may appear cute and slow, but […]
