Researchers have found obsidian spearheads dated 85.000 years ago before the development of Homo Sapiens (280.000 years ago). This is a very complicated process, requiring numerous steps and lots of concentration and skill This has 2 possible explanations: either humans evolved much earlier than previously believed, either another species had advanced craftsmanship skills […]
Stanford researchers claim the inherent disordered molecular structure of polymer semiconductors is actually desirable. Current organic solar cells made with semiconducting polymers try to mimic orderly silicon structures as much as possible; this direction of research may be fundamentally wrong according to the Stanford researchers. A balance between molecular order and disorder at the polymer […]
A team from Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard has managed to take advantage of graphene’s unique properties (it’s strength and electric conduction) to create a nano-mechanical system that can create FM signals – in other words, the world’s smallest radio. “This work is significant […]
Most fossils are very fragile, difficult to handle and transport Researchers conducted CT scans on fossils still trapped in sedimentary material, creating 3D models The models were then 3D printed – an accurate, non invasive method to replicate fossils for schools, museums and other researchers Doctors and dinosaurs Being a paleontologist and working […]
An estimate 20% of Americans use some of form of psychotropic medication, amounting to a $34 billion industry. Desperate to ease their problems away with one magic pill, people are flocking in pharmacies to take their regular hits of Prozac, Valium or Vicodin. In the future, however, a new class of drugs may enter the […]
The climate crisis we are facing right now (which for one reason or another many people choose to ignore) has largely been caused by only 90 companies – which between them produced nearly two-thirds of the greenhouse gas emissions generated since the industrial revolution, new research suggests. The study was found that almost all these […]
There’s quite a common belief that if you provide welfare and lots of financial support to the jobless, they will lose motivation to find work and will become lazy and unproductive; that idea is wrong. High unemployment benefits do not lead to people becoming lazy and satisfied with their jobless status, a Europe-wide study suggests. […]
The new drug is the most promising since morphine was introduced – it is 100 times more potent than existing pain medications, but it works at very low doses, without inducing the risk of addiction. Predator snails and painkillers Snail venom in a pill could offer powerful relief for people suffering from severe (acute or […]
As if that would be our biggest concern in the first place, but it’s important to understand, especially for policy makers, that even though dumping CO2 as a byproduct of current energy production methods is a lot cheaper than “cleaner alternatives”, in the long run the balance of economics turn. A new report released today […]
A new genome analysis study suggests that interbreeding between modern humans, Neanderthals, Denisovans and a mysterious archaic population was way more common than previously believed. A Lord of the Rings world Several decades ago, many anthropologists believed that humans, Neanderthals and Denisovans didn’t interbreed at all; as time passed, some evidence of this started popping […]
University of Utah researchers found that female mice that live in a competitive social environment and choose to mate casually with multiple partners give birth to males who are much more attractive to female mice, at the cost of a dramatic cut in life expectancy however. You only have one life, says the sexy male […]
It’s not the cancer tumor itself that kills people, but rather the spread of cancer cells is what ultimately may bring the killing blow to patients. This is called metastasis, and oddly enough not nearly enough is known about how it works. University of Minnesota researchers have devised a pathological method for doctors to assess whether […]
Scientists at the Salk Institute for Biological Studies have for the first time coaxed human stem cells into forming three-dimensional cellular structures similar to those found in our kidneys. The breakthrough could provide a valuable footing for upcoming work that might eventually lead to fully functioning lab-grown kidneys, based on patients’ own cells for bio-compatibility. In […]
Global warming is real, it’s affecting us all, and it’s gonna get worse – and we have nobody to blame but ourselves. The IPPC report The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body with the purpose of providing ‘comprehensive scientific assessments of current scientific, technical and socio-economic information worldwide about the […]
An international team of researchers led by Ralf Tappert, from the University of Innsbruck, reconstructed the composition of Earth’s atmosphere of the last 220 million years by analyzing modern and fossil plant resins. Their results indicate that atmospheric oxygen was considerably lower in Earth’s geological past than previously assumed – providing valuable information about current […]
Geologists have now found the most compelling evidence of granites on Mars – something which prompts more complex theories about the geology and tectonic activity on the Red Planet. Granites and basalts Granites are igneous rocks, pretty common on the surface of Earth. It is often called a ‘felsic’ (white rock) – because it is […]
There’s only so much you can cram into conventional magnetic storage devices. We’re already seeing these slowly, but surely lose ground in the face of solid-state drives, which offer more storage density and don’t have any moving parts (last longer, make no noise, etc.). What about even further ahead in the future? Well, it’s most […]
In quite an interesting discovery, Wildlife Conservation Society biologists have discovered cave paintings made by hunter-gatherers between 10,000 to 4,000 years ago while studying wild animals in the Taboco region. An unexpected find To add more mystery to the situation, the discovery was made in 2009, but it has been kept a secret until now […]
In a synergy between biology and electrochemistry, researchers at MIT cleverly exploited genetically modified viruses to assemble metal molecules into extremely thin nanowires that can be used as cathodes in a lithium-air battery. This type of battery has been thoroughly researched in the past few years and has sparked the interest of scientists because of […]
Paleontologists have unearthed skull fragments in Tibet belonging to an ancient “big cat” species, which apparently may be the oldest discovered thus far. The fossils have been dated between 4.1 and 5.95 million years old and belong to a previously unknown species “similar to a snow leopard”, according to US and Chinese palaeontologists. “This cat is […]
A team of researchers at Washington State University achieved a dramatic 400 fold increase in electrical conductivity for a crystal after it was accidentally left exposed to light one day. This readings are attributed to photoconductivity, a phenomenon which causes a material to become more electrically conductive due to the absorption of electromagnetic radiation such as […]
A few years ago ZME Science reported the peculiar case of Brooke Greenberg, a woman who was born prematurely at just four pounds but never physically developed into an adult. Her condition baffled her doctors as well as the scientific community who even to this day hasn’t managed to pinpoint what exactly was wrong with […]
The world’s most complex malware ever created, the Stuxnet virus which was designed and enforced by the U.S. and Israel against Iran a few years ago, may have ended up infecting the International Space Station according to leading security analyst Eugene Kaspersky head of IT security at Kaspersky Labs. The virus was designed to only attack specific […]
To say that finding evidence of how life on Earth was 3.5 billion years ago is hard would be an understatement. Reconstructing the rise of life in its early stages is a monumental challenge – the evidence is only preserved in Earth’s oldest sedimentary rocks, and sedimentary rocks of that age are very hard to […]
Music isn’t only restricted to humans – music skills evolved at least 30 million years ago in the common ancestor of humans and monkeys, claims a new study that tries to explain why for example chimps drum on tree roots and monkey calls sound like singing. It’s one of the big puzzles in biology and […]
A strange evolutionary alliance between trees and the ants that guard them has a sinister explanation, a new study suggests, after studying ants hooked on nectar. Bodyguard ants and addiction In Central America, ants act as bodyguards for acacia trees, defending them not only from weeds, but also from animals, in exchange for accomodation and […]
From an evolutionary psychology stand-point, one can genuinely assume that a stepparent won’t invest the same amounts of energy and care for their wards as genetic parents often do. This behavior may in some cases turn to an extreme, especially if a new child is born in the family after a stepparent enters the scene, […]
The past 12 months have been 0.22 degrees Celsius warmer than any other equivalent period prior to 2013, and Australia is steadily on track for the warmest year ever. Warmer and warmer A new Climate Council study, titled Off the Charts, says that the country has just had its warmest ever 12-month period, from 1 […]
Using a range of cheap materials arranged in a specific manner, researchers at Duke University have demonstrated a device that captures microwave signals, such as those relayed by WiFi or even satellites high up above in Earth’s orbit, an converts this free, lost energy into electrical current. The harvesting and conversion efficiency of the device […]
You’ll be pretty impressed by this novel research. Scientists at University of Iowa have developed an ingenious biopatch which expels nanoparticles containing DNA that instructs cells to turn into bone. Practically, you just apply this patch over a damaged area that needs reconstruction, dental surgery site or congenital bone defect and the genes do the rest of […]
A study published earlier this week in the Proceedings of the National Academy correlated 93 small earthquakes in Texas (near a city called Snyder) with underground injection of large volumes of gas, primarily carbon dioxide, in a technique called CO2 flooding. Not fracking, but flooding CO2 flooding is a technique that doesn’t refer to extraction, […]
In Greek mythology, Narcissus fell in love with himself after gazing upon the splendor of his own reflection. A pathological admirer of his beauty, Narcissus eventually died of grief for not being able to reach the beautiful young man in the water. When thinking of Narcissus, whose story birthed the term narcissism to describe inordinate […]
At the beginning of the year the most powerful meteoroid strike since the infamous Tunguska event took place in Russia, over Chelyabinsk. The meteor exploded many kilometers above ground, however the event released so much energy that it appeared much brighter than the sun and the ensuing shock wave caused billions of rubles worth of damage […]
The human body is a complex biological entity in seemingly perfect harmony as thousands of components play their part in tandem. Discovering, describing and understanding how each of this body parts function and work together is the primary role of human anatomy. Some of you might be surprised to find that human anatomy is yet […]
The human brain is possibly the most complex entity in the Universe. It’s absolutely remarkable and beautiful to contemplate, and the things we are capable of because of our brains are outstanding. Even though most people might seem like they’re using their brains absolutely trivially the truth is the brain is incredibly complex. Let’s look […]
A laudable, ambitious initiative is nearing fruition: the US$90-million Transportable Array, a moveable grid of seismometers that blankets America. Since 2004, the set of 400 seismometers, loaded on trucks, have gradually marched, from the Pacific coast across the Rocky Mountains and the Great Plains and is finally reaching the eastern coastline. Whenever they arrive at […]
Why the US is against GM labeling is beyond me. In the European Union, all products must clearly state if they contain or not genetically modified organisms. However, in the United States, where over 60 percent of processed foods contain a genetically altered ingredient, GM labeling is not required, and consumers remain largely unconcerned about […]
This “How to” may not be that relevant in modern times, but in the XIV and XV century, I could think of a few civilizations that would have loved to learn how Chinese engineers moved huge volumes of rock from quarries tens of miles away. Such blocks of stone, weighing at least 100 tonnes, were […]
Researchers have found that methane-decomposing bacteria from hot springs need rare earths to produce the energy they need to survive. Rare Earth Elemenets (REE), or rare earth metals as they are sometimes called are a group of 17 chemical elements in the periodic table, specifically the so-called lanthanides plus scandium and yttrium. They are among […]
In the US alone there are an estimated 100 million daily coffee drinkers, each contributing to a booming $18 billion industry. Of these, 68% claim they have their first coffee within the first hour of waking up. As a coffee drinker, I find myself guilty of the same practice, but apparently this isn’t the best […]
Crossing the riverbed of Carrizo Creek in Oklahoma, a series of tracks made by a two-legged dinosaur have been preserved in time for 150 million years. The tracks reveal a most clumsy scene, as the dinosaur in question slipped for a second before going back to his beaten path. When first analyzedin the 1980s, paleontologists […]
Some people are better navigators than others, i.e. men better than women. Whether you can make your way effortlessly through the woods to reach a safe house or get seemingly lost on your way home from a different bus stop, it doesn’t make that much of a different at a sensory level. Navigation is often […]
There’s been a lot of praise and finger pointing alike around the hydrogen economy, and whether or not fuel cells can be scaled to reasonable levels i.e. becoming actually useful. There are a lot of problems with fuel cells in terms of their economy. Fuel cells are some of the most efficient energy converters current […]
A lot of Americans are buying into the electric car dream. As noble as this may be, despite the fact that EVs are far from being pure ‘green’, there are numerous challenges faced by the industry which have deterred a lot of folks from switching to electric cars such as the one offered by Tesla Motors. […]
The U.S. is not only the biggest energy consumer per capita in the lord, but also the leading media consumer. An estimated 6.9 zettabytes of media flows to individuals and households in a year or 6.9 million million gigabytes. That’s almost twice as much than in 2008 and according to the latest “How Much Media? 2013 […]
A giant platypus fossil, measuring more than 1m long (3ft) was discovered in Queensland, Australia. The animal lived 5-15 million years ago, as paleontologists explain in the journal Vertebrate Paleontology. Until now, the oldest fossil was dated 100.000 years ago. As if the evolutionary status of the platypus wasn’t extraordinarily complicated as it is, this […]
Healthy wildlife populations aren’t always good news. Sweden’s largest nuclear power plant had to be shut down for three weeks in September after a mass of jellyfish clogged its cooling water inlet. A swarm of baby jellyfish essentially destroyed Northern Ireland’s farmed-salmon population in 2008 through stings and oxygen deprivation. A Japanese trawler capsized in […]
Any dog lover will tell you if you see a dog wagging its tail it’s a sign that the dog is happy. Apparently, there are subtle signals given off by variations in tail wagging and these are used to communicate with other dogs what their stance is. Researchers at University of Trento, Italy found that happy dogs […]
After performing an exhaustive quantitative research across numerous plant species, scientists at UCLA’s College of Letters and Science have found that leaf design is governed by a set of fundamental mathematical expressions, underling once again the elegance of nature. The basis of their research was “allometric analysis”, that is to say the study of an object’s evolution […]
What is creativity? Although definitions vary, one might be inclined to say that creativity, ultimately, is anything that has to do with ideas – generating them, building them, transforming them into reality. There are a lot of tests that measure creativity and chances are if you’ve been to a job interview recently you might have […]
