Today, cancer is typically treated through highly invasive, painful and low efficiency treatments. Doctors resect the tumors, do radiation therapy, and then chemotherapy. This process is actually more stressful and painful to the patient than the cancer itself, but it does save lives sometimes. Scientists all over the world are hard at work developing alternative […]
A team of evolutionary biologists at Indiana University has shown for the first time that asexual lineages of a species are doomed not necessarily from a long, slow accumulation of new mutations, but rather from fast gene conversions which unmask preexisting genetic mutations. The groundbreaking research started with the sequencing of the entire genomes of […]
Every time we’re engaged in a certain action, the sounds we produce while walking, eating, even playing music are tuned down a notch in volume by the brain. For instance, during a conversation your voice will be perceived as quieter than it actually is in reality, since our brain want to receive clearer the information […]
With new insights derived from Game Theory, University of Pennsylvania biologists offer a mathematically based explanation for why cooperation and generosity have evolved in nature. Their work relied on the work of John Nash, who proposed the famous Nash equilibrium and advanced Game Theory in the 1950, as well as those of computational biologist William […]
Land clearing and human habitation put significant pressure on local species – combine this with globalization and a general recklessness of the population, and you get a big, negative impact (both environmental and economic) from invasive plants. But invasive plants aren’t something new – they’ve been around for hundreds of millions of years. Scientists have […]
Some 5.000 years separate us from the birth of Ancient Egypt, in 3.100 BC. Add another 5.000 years, and you still haven’t reached the date when Göbekli Tepe was built. The temple (now in southern Turkey) took shape over 11.000 years ago, around the same time Plato’s hypothetical Atlantis goes under, 5 millennia before the […]
=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 […]
One of the smallest amphibians in the world, the Gardiner’s Seychelles frog, is also one of the most eccentric. The frog doesn’t stand out through an over-glamorous coloring or some unique, wild mating call, but rather as a result of one of its weird biological features. This frog doesn’t have ears – yet it can hear. […]
Somebody in Tokyo is reading Game of Thrones: the Japanese government has announced plans to create a wall of ice underneath the contaminated area to contain the water leaks from the Fukushima nuclear plant. Prime Minister Shinzo Abe said his administration will provide the money for this. “The government needs to resolve the problem by […]
A 350 million year old fossilized scorpion has become the world’s oldest known land animal to have ever walked the supercontinent Gondwana. Ancient history It’s 350 million years ago – take a moment to ponder that. Take a long human lifespan of 100 years, and multiply it by 100, and again by 100 – now […]
A new study has shown that young men are threatened when their female signficant others are more successful than them, ultimately triggering their fear that the partner might leave them – and it’s exactly this fear which usually gets them. The researchers conducted their study, published online in the Journal of Personality and Social Psychology, […]
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 […]
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 […]
Honeybees are exquisite and majestic beings, which have always caught the imagination of people. Bees are typically associated with feminine energy, because they are ruled by queens, particularly with the roman goddess Venus. In some cultures, bees also represent wisdom. From a biological point of view however, bees could be definitely associated with motherhood. Without bees, […]
Geophysical data from Greenland have revealed the existence of a canyon comparable in size with the Grand Canyon beneath the ice sheet. The canyon has the characteristics of a winding river channel and is over 750 km long and it is often as deep as 800 m. This immense feature is thought to predate humanity […]
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 […]
Most medical research looking to identify the mechanisms of a disease or test treatments rely on animal models. While very useful, mice for instance (a favorite lab pet for researchers) do not have nearly the same brain structure or genes as humans. Even if some genes and proteins scientists target are the same both in […]
Usually, it’s scientists who gather the data, but this time, they were the data themselves – a poll of 3700 American researchers showed that a significant portion of scientists are receiving less federal help than they were three years ago, despite spending much more time writing for grants and applying for projects. Nearly one-fifth of […]
A surprisingly diverse range of life forms exists deep in the oceanic crust, but they live at an extremely slow pace. Long lived bacteria, which reproduce only once in 10.000 years, have been found in rocks 2.5km below the ocean floor, rocks which are 100 million years old. Viruses and fungi have also been found […]
In a mind-boggling and, frankly, a bit frightening breakthrough, researchers at University of Washington have devised a brain-to-brain interface that for the first time has allowed the remote exchange of information between two human brains. The test that demonstrated the technology, although simple in nature, shows of a powerful display of force. One researcher (human brain […]
Theoretical Physicists John Preskill and Spiros Michalakis sat down for a short talk in which they describe how quantum computing differs from the classical view (i.e. digital computers). They first go on about the fundamental, key aspect of the quantum world: the laws that describe and govern things at the tiniest level differ from those […]
Crows, like most other species from the corvid family (ravens, rooks, etc.), are some of the most intelligent animals on the planet, actually rivaling apes and dolphins. Tool use is common among these birds, but where they shine is in their social and emotional intelligence. For instance, a few years ago I reported how ravens point […]
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 […]
Farmers, with the help of researchers in the field, have been desperately trying to develop new insecticides that can ward off pests looking to claim their crops. These products work with a varying degree of effectiveness. For one, the insect pests tend to develop tolerance and new solutions have to be developed, and of course […]
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. […]
It has been previously shown that during ovulation, women tend to increase their attractiveness to men (though not necessarily conscious). Not only do they change their voice pitch [1], but they also tend to dress more fashionable [2]. A new study published in Psychological Science adds to this growing body of research by suggesting that […]
I’ve written about our incredible biological ability to gather information about our environment by sensing electromagnetic radiation. As complex as our eyes are however, light holds far more information than what we are able to perceive with our eyes. Science has given us the means to determine far more than just that there is a […]
What do volcanic eruptions, oil spills, sewages and chimneys all have in common? Not much at a first glance – but if you ask Peter Baines, a scientist at the University of Melbourne in Australia, they are tightly connected; in all these events, a fluid rises into a environment stratified by density (like the atmosphere […]
A 52-year-old, part-time graduate student with no previous training in psychology and little training in math aside from high-school has discredited a very cited paper published in 2005 in American Psychologist. The paper, then written by Barbara Fredrickson and Marcial Losada suggested a mathematical ratio between positivity and happiness, claiming that humans thrive when ratio […]
Modern humans started ‘replacing’ Neanderthals some 40.000 years ago, and for a long time, it was thought this came as a result of the more advanced human intelect and a better ability to adapt; but as more and more studies unfold, the Neandertals’ capabilities are still greatly debated. Many scientists now argue that Neandertals had […]
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 […]
A fossil of a small, forest-floor-dwelling animal called Megaconus puts a big question mark on the evolution of mammals – it suggests that its group predated animals, while another one, from its tree dwelling ‘cousing’ Arboroharamiya shows the group belonged to the mammals. The two fossils have paleontologists scratching their heads, not knowing where to […]
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 […]
A few years ago ZME Science reported how a group of researchers at University of Maastricht in Holland were on a mission to grow the first lab cultured ‘hamburger’. After five years of painstaking work and €250,000 invested (backed by Google’s Sergey Brin), an edible version was finally developed and what better way to put it to […]
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 […]
The ramifications of climate change are long and vast, but with all this talk and attention the subject’s been gaining it’s a bit surprising that the mood of humans, and how this in turn affects the world, has been greatly overlooked. For instance, a new study, which has collected and statistically analyzed data from more […]
Your first impression after seeing one or more of the photos featured in this piece might be that these are ‘shopped, painted or feature an astronomical event of some kind. Your assumptions couldn’t be farther from the truth, and believe it or not these beautiful dancing lights over the helicopters’ rotor blades were captured in […]
Somewhere in the far reaches of space (or perhaps in some realm that we have yet to discover), a bunch of really bored cosmic dudes are probably watching us right now. Heck, they’ve probably had their eyes on us for thousands (or even millions) of years already; and they possibly have enough data to compile […]
To most people, 3D printers are still sci-fi, and as a result, envisioning a 3D printer in every home is a huge stretch. But a study conducted by Michigan Technological University scientists concluded that personal manufacturing, like personal computers in their time, will become a common thing – soon. “For the average American consumer, 3D […]
The first use of the umbrella, albeit in a more primitive form, can be traced back to ancient times. In Persia the parasol is repeatedly found in the carved work of Persepolis, while others works such as sculptures frequently depict figures likes a king in his chariot, with an attendant holding a parasol over his […]
How many times did you apply for a job or to enter a graduate program in some school somewhere only to find that the position was filled by someone less capable than you? Now, we’re strictly referring to people genuinely less capable than you, otherwise we’d be hitting the same bias exhibited by the manager […]
Most people don't know this but helium -- the familiar inert gas we all use to inflate party balloons -- is running out at an astonishing rate.
Scientists at the University of Darmstadt, Germany have set a new record after they devised an experimental set-up that allowed them to stop light in its tracks for a full minute. During this time, the light could have traveled 18 million kilometers or roughly the equivalent of 20 there and back trips to the moon. Beyond […]
We all appreciate and love the sun’s gaze in the morning, but truth be told were it not for our planet’s protective magnetic fields the sun’s warm embrace would have suddenly turn into a death ray. So instead of scorching Earth, solar wind bounces off the magnetic field, which leads radioactive particles to circulate the […]
The United States is a country renowned for its history of technological innovation and stewardship. Some of the world’s greatest inventors, though not all of them may have not been born there, first displayed their work in the US. Samuel Colt (colt revolver), A.G. Bell (telephone), Thomas Edison (light bulb, among many), George Washington Carver […]
Most smokers fall prey to the poisonous grasp of cigarettes because they became seduced by the simple act itself, not because of the taste or other pleasures relieved from smoking. There are many aspects that make smoking extremely appealing, especially to attention-seeking young. Despite several policies have been introduced in the past decades to put […]
The prisoner’s dilemma is one of the most famous paradigms and at the same time one of the most discussed case studies in both economics and psychology introductory classes. Basically, two prisoners are each isolated from one another and are presented with two choices: either they turn the other in (sabotage) or remain silent (cooperate). […]
