With Valentine's Day just around the corner, some of you might be tempted to employ some of those spray-on pheromone products. I won't give names, but you must have seen the ads - they're all over TV and the internet. Odorless pheromones are secreted by many animals to attract mates, and while synthesized versions have been shown to work for bees and other insects, the human nose and brain for that matter is a whole different thing.
Chinese researchers ran simulations and found that a pentagon-containing version of graphene is theoretically stable. The 2D allotrope of carbon is made up of atom-thick sheet of carbon atoms arranged in a repeating pentagon pattern, while graphene is made up of carbon atoms arranged in a hexagon pattern, like a chicken wire. Graphene is the strongest material in the […]
A recent report in the Hong Kong Medical Journal describes the case of a baby girl who was born carrying two masses in her body which are likely to be foetuses. But this doesn’t mean that she was “born pregnant” (as some media wrote), but is rather the case of “parasitic twins”. If they are […]
Alfred “Alfie” Date is Australia’s oldest living person, at 109; he’s also a self-taught expert knitter who is doing his best to help penguins in Australia and New Zealand survive oil spills – by knitting them sweaters. He told 9stories he answered the call of Phillip Island’s Penguin Foundation which asked for knitters from around the world to make […]
A new study found that unemployment is one of the main causes for suicide across the world - between 2001 and 2011, unemployment caused approximately 450,000 cases of suicide.
If you claim you're a doctor online, even without providing any proof, people may trust you more than the CDC. A new study has found that online comments have as much power as statements issues by health institutions - and in some cases, even more.
City smog significantly lowers children's IQ, while also raising the risk for Alzheimers disease. A new study has found that children living in highly polluted cities are at an increased risk for detrimental effects to the brain, including short-term memory loss.
Millions of years before rock and roll, LSD and the new age movement, dinosaurs were having a blast in the Cretacious, nibbling on ancient ergot - a parasitic fungus known for its poisonous and potent hallucinogenic effects. The idea is supported by a grass spikelet and ergot sample trapped in a 100-million-year-old piece of amber from Myanmar.
Even after only sleeping for two hours a night, a half an hour nap can restore your protein and hormone levels to normal, a new study has found.
If you're a smoker, I've got some (more) bad news for you - long term smoking thins the cerebral cortex, the outer layer of the brain, responsible among others for memory, perception and language. The good news is that if you've quit smoking, then the effect is reversible.
After reviewing existing literature and statistics, researchers from the University of Warwick have found evidence which suggests a significant relationship between cannabis consumption and the onset (or exacerbation) of mania symptoms. We’ve presented quite a few studies on cannabis here on ZME Science. Our general impression is that due to legal constraints (which are somewhat […]
Mitigating climate change is on the agenda of every world government, but somehow little is done to curb global warming. Echoing a quick-fix approach to life so predominantly engraved in modern culture, some are considering sweeping climate change under the proverbial rug. These so called geo-engineering methods aim to fix climate change by altering the environment, but those ideas that are actually practical today only mask the effects and do nothing to treat the symptoms, a new report signed by 16 top scientists reads. The authors used this opportunity to make an appeal for reducing global emissions, else we might be forced to actually engineer the planet with unforeseeable consequences.
"How many licks does it take to get to the center of a Tootsie pop? The world may never know," a timeless commercial might have us believe. What the world of advertising seems to neglect, however, is scientists' astute resilience to rhetoric. As it happens, it takes an estimated 1,000 licks to reach the center of a lollipop, according to a paper published in the Journal of Fluid Mechanics, by researchers from New York University and Florida State University.
Just like a deep fried scoop of ice cream, comets, such as the much heralded Comet 67P/Churyumov-Gerasimenko which saw a spaceship land on it last year, are thought to be frozen on the inside, wheres the surface is hard and crystallized. The team of scientists at NASA’s Jet Propulsion Laboratory (JPL) and the California Institute of Technology (Caltech) believe the findings further expand our knowledge on comets. Some suggest that life on Earth first emerged thanks to key organic molecules and compounds brought forth by comets colliding with our planet. The more we know, the better we can assess these sort of ideas and, if found viable, how often such events might happen in the Universe.
Climate change is a threat to all life and vegetation here on Earth, but some places are worse off than others. Take Mongolia for instance. Over the past 30 years, a quarter of the country's surface has turned into a desert, while 850 lakes and 2,000 rivers have dried out. This rapid desertification has severely disrupted habitats, making it very difficult for both man and beast to adapt. Even to this day, 25% of Mongolians living in the country are thought to be nomadic, still holding on to ancient traditions from the times when the great Khans swept the world and made it tremble, from Beijing to Rome. In the face of such diversity, the Mongolian people risk losing their heritage and way of life, as they've come to know it for thousands of years.
Billions of years ago, our ancient planet collided with a Mars-sized object called Theia. The impact released tremendous amounts of energy which is thought to have produced a whole mantle magma ocean, which should have erased pre-existing chemical heterogeneities within the Earth. Following the onslaught, a new Earth formed, along with the moon. New geochemical findings hint that the impact didn't completely melt the whole planet, leaving clumps and patches intact. This ancient past is thought to still ripple in Earth's mantle.
Researchers have theoretized for some time that our languages are skewed towards happy words - with some more skewed than others. A new study conducted on 10 different languages confirmed this idea, and also found that Spanish is the happiest language, while Chinese is the most balanced.
Using only energy from the sun, a pioneering artificial leaf system splits water to generate hydrogen - a highly energy dense fuel. When Daniel Nocera, then a professor at MIT, announced his device for the first time four years ago, people were really hyped about it but it soon became clear that making hydrogen was only part of the solution. "The problem with the artificial leaf," Nocera says, is that "it makes hydrogen. You guys don't have an infrastructure to use hydrogen."
We tend to think of pollution as a modern thing; after all, industrial pollution should be, well… industrial, right? Well, not quite: a group of researchers found 400 year old traces of pollution in the Peruvian Andes. The pollution was caused when the conquistadors forced the Inca to mine silver from “mountaintop mines”. Ancient Pollution […]
Lawrence Livermore scientists have devised tiny capsules made up of a highly permeable polymer shell and a sodium carbonate solution that actively reacts with and absorbs carbon dioxide (CO2). Sodium carbonate is typically known as the main ingredient in washing soda, a common household item. The capsules are a lot cheaper and more environmentally friendly […]
The most extensive DNA survey of the NYC subway has revealed that New Yorkers really like pizza and mozzarella, but also that drug-resistant microbes are widespread. They also found traces of the plague, anthrax, and learned that a tasmanian devil never took the subway in the city. In a way, the human body is very similar […]
It’s hard to think that the crust’s thickness (which varies between several and several tens of km) can be affected by what happens on the surface – but that’s exactly the conclusion of a recent study conducted by British researchers. They found that during an ice age, when sea levels are low, the magma that spreads […]
The most efficient solar cells are those that convert incoming concentrated solar power via lenses, the sort you see on the International Space Station or in the sun-soaked Middle East where Shams 1, a 100 MW CSP plant – the largest in the world – operates, powering 20,000 United Arab Emirates homes. Because of their complex nature, […]
If two tape worms infect the same host, they can either cooperate to thrive, or battle it out for complete control. A new study has found that the parasites actively sabotage each other in a competition to seize control of the host. Tape worms are nasty creatures. They live in the digestive tracts of vertebrates […]
Because the moon is tidally-locked to Earth, we’re used to seeing our cosmic neighbor like a stationary lonesome figure. Now, NASA released an animated simulation of the moon’s phase from its so-called dark side, offering an insightful glimpse from the other side of the coin. Far side of the moon – not so dark after […]
We tend to think of termites as pests, but the tiny insects actually play a crucial environmental role, at least in some areas. New research suggests that termite mounds are crucial to stopping the spread of deserts and preserving the vegetation and climate. The results indicate that termite mounds can not only to stop desertification, but […]
In just 7 years, a disease called white-nose syndrome has killed more than 5 million North American bats, almost wiping out entire colonies. The disease has been reported in caves and mines of 25 states throughout the Northeastern U.S. and no treatment or practical way of halting the disease has been proposed. The disease is caused by […]
So, we’ve already discussed about the largest and heaviest organisms in the world, now it’s time to see what the world’s oldest animal is – spoiler alert, this one is also a surprise. If you’re thinking it’s a turtle or an elephant… you’re way off. If you think it’s a whale, you’re a bit closer, […]
NASA is requesting 30 million dollars to begin working on a mission to Jupiter’s moon, Europa, hoping to unlock some of the secrets of alien life. Despite having a frozen surface, the satellite is one of the likeliest candidates for extraterrestrial life in the solar system. Europa is a weird place. At a first […]
A whopping 66 out of the country’s 74 major cities don’t meet the basic air quality requirements, China’s Ministry of Environment said in a report they released. Beijing, the country’s capital, is actually the 8th most polluted city of the country. China has a long standing history with pollution, and despite some laudable measures being […]
Coffee beans undergo several processes before they become the delicious brew we all know. The coffee beans we’re used to seeing, the brown ones with a delightful flavor, are roasted. Raw coffee beans have a different color and smell very differently. So what makes roasted coffee look, smell, and taste so different from raw coffee? The […]
An exciting research found baby chicks also use the mental number lines employed by humans to count numbers, representing them upwards from left to right. The research and those to follow on other animals might help unravel how this basic mental construct, so essential to human intellect, evolved. Think twice before insulting someone by calling him a birdbrain - it doesn't do the birds justice.
The World Health Organization (WHO) says that after more than half a year, the number of new cases of Ebola in West Africa has fallen under 100 - which means that the focus is shifting from containing the epidemic to actually ending it.
The human brain is often described as the most beautiful organism in the Universe. We say this because of the beautiful things the mind, sustained by the brain, can create and imagine. Greg Dunn earned his PhD in Neuroscience at the University of Pennsylvania in 2011, but while his colleagues are fiddling with microscopes to unravel the inner workings of brain cells, he works with a paintbrush to magnify neurons on a canvas. His work shows a brain whose beauty transcends romanticism and awes in its raw form.
Researchers have identified a new class of antibodies that are capable of neutralizing a wide range of influenza A viruses, a discovery that could potentially lead to a universal flu vaccine. The vaccine would be applied only once an, instead of once every flu season today. Protection against all strains of flue, even mutated ones, would be assured for life according to scientists at McMaster and the Icahn School of Medicine at Mount Sinai, New York.
There's no secret that evolution directly contradicts religious views on creationism. What's surprising, however, is that many people who are scientifically literate - that is, they're knowledgeable about scientific topics and appreciate its practical usage on a day to day basis - reject mainstream scientific accounts of evolution and the big bang, Around one in five Americans fall in this scope, according to Timothy L. O'Brien, an assistant professor of sociology at the University of Evansville and the lead author of the study. This suggests that scientific literacy does not necessarily imply accepting well established science when it contradicts deeply entrenched religious views.
At least in the US, there is a huge difference between what the general public thinks and what scientists think – and this is a big problem. Science is at the core of any nation – it influences the economy, the public life, the health… pretty much everything – everybody agrees on this; but despite this […]
A component found in green tea may be very effective at destroying oral cancer cells, while leaving healthy cells alone. The research from Penn State could become very useful in fighting oral cancer, as well sa other types of cancer.
We tend to think that sexual activity slows down and ultimately stops as we end, but a new study has shown that it's not as bad as we think. Over half of all men and almost a third of all women over 70 are still sexually active - with over a third of all people having sex at least twice a month.
Chemists have confirmed the existence of new bond - a vibrational chemical bond. First predicted to occur 30 years ago, the findings yet again show what a complex and constantly evolving field chemistry is.
The next Mars exploration rover will likely feature a helicopter drone, which is expected to act as scouting drone to improve navigation. According to officials at NASA JPL, the drone could help the rover cover three times the distance Curiosity drives on a daily basis. We have Curiosity to thank for loads of new insights […]
Most spiders weave sticky, wet webs to trap their prey, but the feather-legged lace weaver spider, Uloborus plumipes, employs a totally "high-tech" strategy. It spins an extremely thin nano-sized web, which becomes charge with electrostatic energy. Just like dust latches on to your sweater, insects are attracted and stuck to the the web. Biologists believe they've figured out how the spider does all of this in a newly reported paper which might help the industry design and develop ultra-strong nano filaments in the future.
Seattle, an US city with one of the highest recycling rates in the country, is now effectively mandating its citizens to separate food waste from trash cans. Those who do not comply risk a fine, but also a red tag on their garbage cans for all the other neighbors to see. Basically, it's a shaming act - will it work?
If you’re one of those people who believe green coffee pills can do wonders for your health, then I’ve got some bad news for you. Not only do they not work, but the marketer who supported them was given a huge fine for misleading and lying about his product. Remember the “magic” green coffee pills […]
It's believed that 0.5% of all people alive today or millions of people are descendants of Genghis Khan - the founder of the Mongol empire, which became the largest contiguous empire in history after his demise. Research now shows that his prolific breeding wasn't alone in history after another ten huge genetic lineages were discovered. Their founders lived between 2100 BC and 300 BC.
Although generic drugs are often identical to their brand-name counterparts, the effect is often not the same. It's not because the more expensive drugs do something different or better - in fact, it's all in your head. A new study has found that expensive placebos can work better than cheap placebos.
A suborbital rocket carrying six research payloads was successfully launched into the Aurora Borealis. The probe will allow scientists to better understand the energy of the aurora and how this affects the Earth.
When the US Senate finally agreed that global warming is real, I thought we’re finally going to get some progress. The leaders of the US were finally starting to acknowledge the environmental damage we’re causing and maybe even start taking measures against it… it was too good to be true. While the senate agreed that […]
Australian scientists have cured nut allergy in 80% of the children taking part in a probiotic clinical trial. These children’s lives how now been transformed forever, with many more – child or adult – to follow soon. Nut allergy is lifelong and the most common cause of death from food anaphylaxis. Peanuts – back on the […]
An ancient skull found in Israel indicates that early Homo sapiens likely interbred with Neanderthals 50,000 years ago. The female skull is the first skeletal evidence to support the idea that Neandertals and moderns mated. The finding is published in the journal Nature. The Neanderthals (Homo neanderthalensis) are closely related to modern humans, differing in DNA by only 0.12%. Genetic […]
