This weekend, SpaceX is scheduled to deliver cargo and other much needed supplies to the International Space Station via its Dragon capsule. Among the supplies is a surprise for the astronauts on board: the latest high tech gadget from Microsoft, the HoloLens. If you missed ZME Science's feature of the HoloLens, well you're in for a treat if this is the first time you hear about it. Basically, the tech involves using holographic computing which enables you to mix virtual reality with ..actual reality. Holograms following in your kitchen, weather reports on your coffee cup. Really, anything is possible with the HoloLens, let alone in the final frontier: space.
Anecdotal observations and even some studies claim that listening to extreme music like heavy metal, punk or hardcore causes anger and expressions of anger, like delinquency or violent behavior. Researchers in Australia, however, found that this isn't the case. After closely following 39 extreme music listeners aged 18–34 years, the psychologists found that extreme music didn't make the participants angrier - even after they were purposely made angry. Instead, when they tuned to their favorite extreme music, the participants exhibited a lower heart rate, which is associated with less angry response, showed an increase in positive emotions.
The team looked at 15-years worth of data on California's grasslands, and documented declining plant diversity from 2000 to 2014 at both the local community (5 m2) and landscape (27 km2) scales, across multiple functional groups and soil environments. They found a link between wildflower diversity decline to significant decreases in midwinter precipitation.
"Fat is bad" seems to be a general rule when concocting dietary guidelines, but fatty foods may be making a comeback for all the right reasons. The latest version of the Dietary Guidelines for Americans, which is due out later this year will eliminate the upper limit for total dietary fat intake.
Meet Matthew, a bright eyes, chubby cheeked baby. On the outside he looks and behaves like any regular baby his age, with one exception: an usually oblong-shaped head. At first, his parents dismissed it as a family feature, but when Matthew turned two months and visited the pediatrician for his regular check-up the doctor immediately […]
Astronomers using the Hubble telescope have identified a warm Neptune-sized planet that is "bleeding" a huge hydrogen cloud - thus increasing the odds of finding liquid oceans on gas giants.
Scientists have discovered and described the only known species of Yeti Crab that resides in Antarctica's Southern Ocean. The crab, which has a white fur all over its body, survives in an extremely inhospitable environment, close to the hydrothermal vents that spew hot water in the freezing ocean.
It's a touchy issue for some - the matter of adoption by homosexual couples. Some argue against this type of adoption, while others claim that there's absolutely nothing wrong with it. Now, a new study conducted by University of Colorado Denver research found that children of same-sex parents experience 'no difference' in terms of social and behavioral outcomes to children of heterosexual couples.
Fasting has been practiced since ancient times as a cleansing process, often accompanied by prayer and periods of seclusion. Famous enlightened historical figures like Jesus or Buddha are prime examples of such ascetic practice. The latter raised fasting to an artform. But fasting needs not be merely associated with spiritualism or religion - it could very well be a great tool to improve your health. Several studies have documented the benefits of fasting, but on the other hand how many of us could go through such excruciating torments, living on water alone for days at a time (some Buddhist monks do it for weeks). After all, low calorie diets are hard enough, let alone not eating altogether. A new study, however, suggests that there might be a way to trick your body it's in fasting mode, and thus reap the benefits, without actually going overboard.
NASA released the breathtaking image you see below, announcing that it is basically X-ray light echoes reflecting off clouds of dust. But this image does more than thrill us amateur stargazers – it helps astronomers figure out how far away the double star system Circinus X-1 is from Earth. “It’s really hard to get accurate distance measurements […]
Lexus, better known for its luxury cars, just released a teasing video unveiling what looks like a genuine hoverboard. But is it the real deal or some lame marketing stunt? I feel like the latter, while a possibility, would severely backfire for Lexus, a highly respectable brand. On the other hand, I guess the kid in me is just rooting for this whole thing to be real.
An extensive meta-analysis of 79 trials which studied the medical benefits of marijuana found that the various cannabinoid compounds did not improve nausea, vomiting, or appetite, but slightly improved chronic pain and plasticity. Moreover, most of the studies were poorly made, lacking control or placebo groups and also showing increased risk of bias. In short, this rigorous analysis found no conclusive evidence that supports the much heralded added benefits of medical marijuana. Side effects were common and included dizziness, dry mouth and sleepiness. The authors note that this doesn't mean that marijuana compounds aren't working as advertised, it's just that the science so far is inconclusive - mainly because of bad reporting and investigative techniques. They suggest more research is necessary, along with more support from the authorities and other able bodies given that we're talking about an extremely widespread drug ingested by millions of Americans each day, legally or not.
A group of UK teenages have invented a condom that changes colors and glows if you/he have/has an STD. Aptly named the S.T. EYE, the condom has a built-in chemical detector that detects infections such as chlamydia and syphilis, and lets you (and your partner) know.
The European Space Agency has confirmed that the Rosetta mission will continue until at least September 2016, when it will most likely land on a comet called Comet 67P.
Researchers from the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) have been trying to figure out how Titan's seas formed - more exactly, how the depressions in which the seas are formed.
Viagra does things to you... but not skin cancer.
A clear, apparently simple plastic chip could eliminate the need for animal testing. The design, which basically mimics the functions of human organs, won the Design of the Year award from the Design Museum in London.
Researchers at University of Hawaii, Manoa in collaboration with a team from the University of Tokyo were surprised to find not one, but two species of deep-water sharks that have positive buoyancy. Most sharks have a negative buoyancy, meaning if they stop swimming they'll sink to the bottom, and some researchers have posited that there may be some species with neutral buoyancy. Finding sharks that defy this conventional wisdom is definitely an important discovery. Now the researchers are trying to find out how the positive buoyancy is attained and whether other shark species have this ability.
Astronomers have discovered a whopping 854 new ultra-dark galaxies which might have large quantities of the elusive dark matter, which makes out most of our universe.
Don't you just hate it when you're looking for support for a service or app you bought, only to be greeted by some monosyllabic robot ? Ok, that can happen just as well when dealing with outsourced tech support, but at least you know you're talking to a real person. Well, that might change sooner than you might think. The singularity is getting closer by the moment. Just take a look at Google's new chatbot which according to the developers has moderate "natural language understanding". In other words, it can roll with the punches and continue the conversation by itself without following predefined question - answer. Of course, after a while you can still tell it's not human (fails Turing test), but that doesn't mean it isn't entertaining. Have a look at how it answers to "what's the purpose of life?".
Thousands of lightning bolts strike the Earth's surface roughly every couple of seconds, but despite their ubiquity this phenomena is somewhat poorly understand. Lightning is also unpredictable. While humans have been placing lightning rods for centuries to increase the probability of striking in a certain fixed point, its path can not be controlled. That may be true in nature, but in the confinement of a lab of the INRS Énergie Matériaux Télécommunications research centre (Varennes, QC, Canada), scientists have defied this common knowledge and used lasers to coax lighting to follow a predefined path.
NASA's spacecraft Dawn is currently orbiting Ceres - a dwarf planet and the largest object in the asteroid belt - in order to study this highly fascinating, yet enigmatic object. For instance, strange and peculiar brights spots on its surface are still puzzling scientists. NASA has kindly shared some of the photos documenting these brights spots, taken by Dawn from only 2,700 miles above the surface.
More job opportunities could be created by investing clean energy sources than fossil fuels.
Geological evidence indicates that our planet has seen five mass extinction cycles since life first appeared on the planet. While they sound like the kind of cataclysmic events that only beardy men with huge boats survive through (read that in a book once, so it must be true), they are actually an integral part of […]
This Friday, the International Whaling Commission issued a report in which it states Japan has failed to provide any reasonable explanation for its mass killing of over 4,000 whales in the Antarctic for the past 12 years. The country says it's hunting whales for research purposes, but clearly it's all a front. A lame excuse. Unimpressed by the report, Japan officials claim there's a debate and lack of consensus (not really), and even though it "acknowledges" the IWC position it will likely continue as before. In other words, they don't care.
A novel, previously unseen self-repair mechanism was reported by a team of researchers at Caltech who studied the moon jellyfish. A lot of animals, mostly invertebrates, grow back their lost limbs after these are bitten off by predators or lost in an accident. The moon jellyfish, however, employs a different tactic altogether: instead of expending a lot of energy to regrow its lost limb, the animal re-arranges the limbs it has left to regain symmetry. Even when it's left with two limbs out of its initial eight, the jellyfish will still re-arrange itself. This sort of mechanism might prove extremely useful in designing self-repairing robots.
A new study on mice shows great promise for treating colon cancer - a simple genetic tweak can turn colorectal cancer cells into healthy tissue in a matter of days.
A research group working at the Australian Grains Free Air CO₂ Enrichment facility (AgFace) in Victoria is studying the effect elevated carbon dioxide will have on crops such as wheat, lentils, canola and field pea. They grow experimental crops in the open, surrounded by thin tubes that eject carbon dioxide into the air around the plants. Findings show that crops have higher yield (up to 25% more), but less proteins. Elevated CO2 also seems to ruin bread made from the grown wheat.
Archaeologists working in Bulgaria have confirmed that they uncovered the oldest prehistoric town in Europe. The town was likely home to some 400 people and dates back to between 4700 and 4200 BC - about 1,500 years before the emergence of the Greek civilization.
We tend to think of the Stonehenge as a lone giant, huge blocks of rock towering over the quiet British landscape. But as a new study has revealed, Stonehenge was likely a diverse and vibrant place, a complex of different religious and cultural settings. Painting Stonehenge in New Light Using geophysical techniques (mostly Ground […]
It's one of the best ideas I've read in a long time - motivating people to donate blood, and telling them when they're saving lives. Stockholm-based blood service called Blodcentralen has come up with the idea of giving donors an automatic message whenever they save a life.
A long term study conducted by US researchers has found a connection between levels of DDT pesticide and breast cancer - women with high levels of DDT in their body were four times more likely to develop breast cancer.
Research based on recent observations of a nearby gamma-ray burst, GRB 130603B, help explain how gold, silver and other heavy metal atoms are created.
They call them the Catacomb Saints – ancient Roman corpses that were exhumed from the catacombs of Rome, given fictitious names and sent abroad as relics of saints from the 16th century to the 19th century. They were decorated with extreme lavishness, as you can see below. But why – why would they be decorated with […]
It almost looks like a sci-fi movie; in a small, crammed room at the Goddard Space Flight Center, a group of brilliant NASA researchers are discussing ways to protect our planet from dangerous asteroids. But this is not a movie, it’s reality – and it’s happening now. So how big is the threat from asteroids? Spoiler […]
Astronomers have discovered the oldest known stars lurking in a super-luminous galaxy - they may very well be among the very first objects that formed in the history of the Universe.
The Moon doesn’t have an atmosphere, but it is surrounded by a thick dust cloud; the dust constantly falls down to the lunar surface, but new dust constantly jumps to replenish it. The pattern of dust falling back to its home “in due time … will fill in craters,” says the University of Colorado, Boulder’s Mihaly […]
It's no secret that many animals can sense the Earth's magnetic field, but until now, researchers didn't know exactly how they could do this - what the sensor was. Now, a team from the University of Texas at Austin has found a simple, antenna-like structure in the brain of the simple worm C. Elegans that appears to be able to detect magnetic fields.
The microbiome, or the collection of bacteria living inside humans and other organisms, is an important topic in research today, because many scientists have made connections between different diseases and illness to the populations of bacteria inside us, specifically in our guts. Previously, ZME Science has covered what the microbiome is and several important studies.
At the center of every raindrop there is an impurity (dust, clay, etc) – basically all raindrops have something like that at its core, just like pearls do. So in a way, raindrops form just like pearls. Let’s look at this phenomenon in more detail. In one form or another, water is always present in […]
When it comes to the appendix, things are still pretty unclear, but one thing’s for sure: if you develop appendicitis, you need surgery to have your appendix removed. But now, a new study found that antibiotics could eliminate the need for an appendectomy. The appendix is a blind-ended tube connected to the cecum. Its exact role […]
Wild bees provide environmental services worth $3,250 (€2,880) per hectare per year - accounting for billions, globally. Writing in Nature Communications, study authors quantify how much bees are doing for us, and stress that despite all their immense value, we still don't have a concrete plan to stop their numbers from dwindling.
We tend to think of the Earth's water as an inexhaustible resource; after all, you learn the basic water cycle in first grade - water moves from the rivers to the oceans and then evaporates into the atmosphere and then it comes back as rain - so how could it be disappearing? Well, the reality is much more complex than that, and as two different studies showed, we may actually be heading towards a major water crisis.
In a world where in only a few decades we moved from clunky phones to wireless satellite-connected devices that allow you to be anywhere and do anything on the internet, it seems only normal that scientists will take it to the next level - to your brain. Already tested on mice, this fine mesh fits inside a syringe and unfurls on the brain to monitor its activity.
Among the best thing about being a biologist is you get to name things when you discover it. Now, a marine researcher in California will name one of the cutest invertebrates we've ever seen: so adorable, that it might actually be named 'adorabilis'.
In only 15 years, renewable energy (wind, solar, hydro) could surpass fossil fuels as the main provider of energy. According to a new International Energy Agency (IEA) report, renewables could provide more than 50% of the energy market by 2050. But even so, they warn, without bolder emission cuts, we'll be blowing past our current climate targets.
Ocean acidification, one of the often ignored dangers associated with climate change is becoming increasingly worrying. As our climate becomes hotter and hotter, the oceans become more and more acidic, and this threatens some animals' ability to create and maintain carbonatic shells.
MIT researchers have managed to create incredibly cold molecules, much colder than even interstellar space. In this new experiment, sodium potassium (NaK) molecules were brought down to 500 nanokelvins, just a touch more than 0 Kelvin - the absolute lowest possible temperature.
Some 30 million years after dinosaurs emerged, they managed to rise up and dominate much of the world - then all clumped together under a supercontinent known as Pangea - except the tropics. Why dinosaurs proved so successful in higher latitudes, but failed miserably in the tropics has perplexed scientists. A possible explanation might be that during those times the tropics had an unpredictable climate, rapidly shifting from wet to dry due to a high concentration of carbon dioxide. This hypothesis is supported by a detailed analysis performed on samples collected at the Ghost Ranch in northern New Mexico, a site rich with fossils from the Late Triassic Period.
A group of international researchers unveiled the world's thinnest light bulb. Remarkably it uses a carbon-based filament, just like Thomas Edison used in 1879 for the first truly commercially-viable incandescent bulb. Unlike Edison, however, the group used carbon in its pure form and ultimate size limit - one atom-thick graphene sheets. Remarkably, the tiny bulb emits light visible to the naked eye. Of course, these sort of designs aren't about setting milestones, though it's always interesting to see how low or high down the scale you can go with engineering. Mostly, graphene-based light sources might prove useful for optical communications where bits are transmitted via packets of photons, instead of electrons.
