Stealth nanoparticles sneak past immune system’s defences

Most of the time, when you’re sick, you want to deliver drugs and imaging agents to diseased cells or tumours where they’re needed most – that’s a problem researchers have solved quite a while ago, we can get particles pretty much wherever we want to. The thing is, most of the time, these agents are […]

How some dinosaurs got enormously long necks

The longest creatures to ever walk the Earth were the long-necked, long-tailed dinosaurs known as the sauropods. But why did these huge vegetarians grow such huge necks, reaching up to 15 meters? That’s six times longer than that of the current world-record holder, the giraffe.   “They were really stupidly, absurdly oversized,” said researcher Michael […]

Get Responsible Pain Relief When Taking Acetaminophen

The dangers of prescription drugs A while ago I wrote a post on the dangers of prescription drugs; the next day, I woke up to see many concerned emails regarding responsible medication, self medication, and other related topics. I tried my best to reply to each and every one of them, but I figured since […]

Star in our galaxy is almost as old as the Universe

A metal poor star located in the Milky Way galaxy, “just” 190 light years away from our Sun is 14.46+-0.80 billion years old – nearly as much as the age of the Universe! All stars follow a stellar evolutionary path; by knowing some parameters about the star (such as mass, luminosity, and surface temperature), astronomers […]

White House directs open access for government research

I had no plans whatsoever for this Sunday evening. To be quite honest, I didn’t feel like writing an article as I was enjoying my tea and yogurt cake. But then, I came across this; and I just had to get on it as fast as possible, because this is big news people. The Obama […]

Watery past challenges theory of moon's origin

According to a new study, the generally accepted theory on lunar formation may have to be reexamined. A relatively recent study has found water in the Moon’s original crust, which means that water found in those rocks didn’t come from an outside source, but was already there when the Moon was formed – something impossible, […]

Scientists find protein that stimulates bone growth in humans

A new study conducted by US researchers has found that a protein called Jagged-1 stimulates stem cells to differentiate into bone-producing cells, possibly saving or improving the qualify of life for millions of people. The fact that their research was peer reviewed and accepted for publishing in the Stem Cells journal definitely backs the validity […]

Millionaire planes private trip to Mars within five years

Millionaire Dennis Tito, 72, is widely known as the first private citizen to fly into space in 2001. But being the entrepreneurial spirit he is, he wants to go even further  – he plans to send two astronauts to Mars in 2018. We’re still awaiting for the next week conference in which he will announce […]

Jupiter's moon Europa much more likely to host life - no mission planned yet

As the search for life on Mars intensifies, it’s good to remember that there are other places in our own solar system that are much more likely to host life. This may be a “captain obvious” moment for some, but may come as quite the surprise for others. Europa, despite its frozen surface, is thought […]

CalTech president moves to Saudi Arabia University

Jean-Lou Chameau, the president of the California Institute of Technology in Pasadena announced that he will be leaving his post at an unspecified time to head the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia. I think this is important not because of the move itself, but rather what it symbolizes. […]

Holy Carp! Giant goldfish invade lake tahoe

A new type of lake monster has been found, in the depths of Lake Tahoe: gigantic goldfish; and as cute as they are, their influence is just disastrous for the local ecosystem. The goldfish is an invasive species for that environment, adapting to the situation so well that it pretty much annihilated its competition, growing […]

Scientists search for unparticle in the Earth's mantle - find nothing, still happy

Particles and unparticles Ok, we know a lot about particles – from electrons and neutrons to the more elusive quarks and leptons, and to the holy Graal of the Standard Model – the Higgs boson; but what’s an unparticle? Well, the Standard Model is just a theory, and there are other theories out there. Unparticle […]

Flowers use electrical signals to summon bees

Pollination is the game, “summon bees” is the spell, and electricity is the mana – that’s how I’d try to explain it to a gamer. A little more on the serious side, flowers advertise presence of nectar to bees using electrical signals, basically indicating if they’ve been visited by another bee or not. Usually, plants […]

Cure for the hangover possibly found

In a promising discovery for students and party aninals all over the world, a team of researchers led by UCLA engineers has identified a method for speeding up the body’s reaction to alcohol consumption – practically elimining the hangover. Researchers take their hangovers really seriously – in a paper published online Feb. 17 in the […]

NASA’s Kepler telescope is on a roll – recently, astronomers working on it discovered a new planetary system that is home to the smallest planet yet found orbiting a star similar to our sun. A similar star, a different system The planets are located in a system researchers call Kepler-37, just over 200 light years, […]

Prescription Drug Overdoses Killed 23,000 Americans in 2010, more than heroin and cocaine combined

In 2010, prescription drug overdoses killed 23,000 Americans, while cannabis continued its over 10.000 year history of not killing anyone by overdose. Actually, there is no physical way to overdose on smoked or ingested cannabis, making it basically one of the safest, most natural, non-toxic painkillers, sleeping aids, and stress relievers on the planet. However, […]

NASA's Curiosity rover confirms first drilled martian rock sample

Despite some initial worry, Curiosity’s drill worked out just fine, and now, the rover has revealed historic images that confirm it has obtained the first samples from the inside of another planet. No other rover or device has drilled to another planet and collected a sample from its interior. “Seeing the powder from the drill […]

Using caddisflies and jewelry to create stunning works of art

The common caddisfly is, as the name calls it, common. They’re usually found near lakes, streams, ponds and rivers, and often used as a bait for trout fishermen. Their larva are aquatic and they create protective silk cases which incorporate bits of material from their surroundings, such as gravel, twigs or small pieces of shell. […]

A book on the Cambrian - with some mind blowing illustrations

Paleontologists have found evidence of animal life dating back at least 635 million years. Those animals acted much like today’s sponges, stuck in the sea floor, filtering water particles for useful nutrients in the sea. But just over 100 million years later, during the Cambrian explosion, life really started to pump its engines. All sorts […]

Jurassic records warn of risk to marine life from global warming

The massive, global risk that global warming poses has once again been highlighted by researchers – this time, by geologists studying fossil records. It’s good to learn from your mistakes, but it’s even better to prevent than treat, and learn from the past (even though it’s not your past) – and paleontology is really good […]

How seals sleep with only half their brain

A new study led by an international team of biolgoists has shown just some brain chemicals allow seals to sleep with only half of the brain. “Seals do something biologically amazing — they sleep with half their brain at a time. The left side of their brain can sleep while the right side stays awake. […]

Biomarker explains why some people catch colds more often than others

Researchers from the Carnegie Mellon University have identified a biological marker in the immune system that (starting from about age 22), predicts the probability of getting a common cold. They found that telomeres play a big part in this likelihood. Telomeres are regions of repetitive nucleotide sequences at each end of a chromatid, which protect […]

Dolphins call each other, not by name, but by whistle

Every bottlenose dolphin makes its own distinctive sound, a high-pitched “eeee” through which they announce their presence. However, dolphins are also great at mimicking sounds, being able to copy even intricate computer generated sounds; this made researchers curious to see if dolphins can in fact mimic each other’s sound, and how they use this ability […]

First baby portrait of a giant armadillo

The giant armadillo, Priodontes maximus by its scientific name, or the tatou, as it is colloqually called was once found widely throughout the tropical forests of eastern South America, but now, thanks to deforestation and human city expansion, it faces extinction. It’s quite a rare sight to see one, but with patience and knowledge, Brazilian […]

Cassini sheds light on cosmic particle accelerators

During a chance encounter with an unusually strong blast of solar wind at Saturn, NASA’s Cassini spacecraft detected particles being accelerated to ultra-high energies (like those at the LHC); this acceleration is similar to that which takes place around distant supernovas and provides a valuable in-situ study environment. The Cassini spacecraft is an absolutely stunning […]

Research finds direct correlation between heart attacks and ozone and air pollution

Based on a massive set of data collected from Houston by Rice University researchers, there is a direct correlation between out-of-hospital heart attacks and levels of air pollution and ozone. Rice statisticians Katherine Ensor and Loren Raun announced their findings today at the American Association for the Advancement of Science (AAAS) conference in Boston – […]

This week, connect with astronauts from the ISS

NASA’s really trying to step up their social media game, and this is definitely good news. This week, NASA’s social media followers and their guests will have the unique opportunity to talk to three of the six crew members aboard the International Space Station, as well as the scientists and engineers involved in the project. […]

Ancient Fossilized Sea Creatures Yield Oldest Biomolecules Isolated Directly from a Fossil

Paleontologists have long believed that complex organic molecules couldn’t survive fossilization; but to contradict this long standing belief, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, feature exactly that type of molecules.   The animals i n case are called crinoids, but are probably better known today as “sea lilies”; they are absolutely […]

The more you sit, the more likely you are to suffer chronic diseases

Kansas State University researcher Richard Rosenkranz, assistant professor of human nutrition concluded that there is a direct connection between how much you sit and how likely you are to suffer chronic diseases; he conducted the study on middle-aged Australian males and published it in the International Journal of Behavioral Nutrition and Physical Activity. He worked […]

Only in the US: say that dinosaurs and humans lived side by side, get good grades

If you’re in a biology class in Europe, and you say that humans appeared on the Earth a few thousand years ago, or that they lived side by side with dinosaurs – you’re gonna get an F. It doesn’t matter if you’re from France, Spain, Russia or Albania, you’re gonna get an F; but in […]

Influential few predict behavior of the many - on all scales

As Niels Bohr once pointed out, to fully understand how a living organism works, you’d have to take it apart in the smallest of parts; since this is not something you can actually do, organisms, which represent systems of very high complexity, are impossible to track and understand in all their details. The few and […]

Wanted: 500 year old arrest warrant for Machiavelli found

A British academic has stumbled upon a 500 year old warrant for one of the most famed people in history: Niccolo Machiavelli. Prof Stephen Milner from Manchester University discovered the historic document almost by accident, as he was browsing through town criers and the proclamations in the Florence archives. The 1513 proclamation, which called for […]

GeoPicture of the week: The map that changed the world

Look at this map; take a good, long, hard look at it. William Smith created it in 1815, 200 years ago. It’s the first nationwide geologic map, which is why he is sometimes referred to as the father of British geology, and it’s pretty darn accurate! His story and absolutely stunning work has a sour […]

Picture perfect: quick, efficient chip eliminates common flaws in amateur photographs

Your smartphone amateur photos could be instantly converted into professional-looking pictures at the touch of a button, thanks to a chip developed by MIT researchers.

Dark matter discovered for the first time? Significant discovery coming in 2 weeks

A new, probably significant discovery will be published in two weeks, the leader of a space-based particle physics experiment said Sunday at the annual meeting of the American Association for the Advancement of Science. Why this is important Dark matter is every bit as mysterious and cool as it sounds; from what we know so […]

Higgs boson data could suggest that our Universe will be swallowed by an alternate reality

So, remember that Higgs boson discovery we got all excited about a while ago? You know, validated the Standard model, proved our understanding of the subatomic world not wrong, and all that? Turns out, that same data could very well be an obituary for our Universe – at least that’s what Joseph Lykken of the […]

Obama funds brain mapping, interesting questions arise

This week, the Obama administration has announced plans to pursue a 10-year, $3 billion research effort aimed at mapping the human brain in “its entirety”. The project, called the Brain Activity Map, is designed to help scientists better understand how the ~100 billion neurons interact in our brains. Initially, the announcement was met with applause, […]

How oceanic iron influences global temperature

I just swear, science is just like fashion sometimes – some treands just reappear time and time again over periods of time. What am I talking about? Well, this is one of the first posts I’ve ever written on ZME Science, all the way back in 2007 (man this brings out memories!). Basically, back then, […]

Be careful, kids - high grades are contagious

Highschool students whose friends have higher grades than them have a significant tendency to raise their own grades over the course of a year, a study conducted by Hiroki Sayama from Binghamton University and his collaborators from Maine-Endwell High School in Endwell, New York, including 4 high school students. Previous research had already shown that […]

Dogs understand humans' point of view - are much more likely to steal food at night, when they can't be seen

A study conducted by Dr. Juliane Kaminski of the University of Portsmouth’s Department of Psychology concluded that when humans forbid dogs to eat foods, dogs are 4 times more likely to steal the food in the dark, when they think humans can’t spot them. It’s interesting to see how dogs actually adapt to what they […]

Ozone layer hole hits record low

According to a new research, the ozone layer has hit a new record low – but this is not necessarily a good thing. It is actually believed that hotter temperatures help the layer, and record high temperatures brought the hole to the lowest size observed in the past decades. The hole, located above the Antarctic […]

Sea Slug boasts disposable penis

Well we all use disposable tissues, dishes, I’ve heard of disposable tails of even limbs, but a disposable penis? Talk about taking things to the next level… But that’s exactly what this sea slug has. After mating, it simply discards its penis, grows a new one, and can even have sex again the same day. […]

Water is running out in the Middle East

As I keep telling people, water isn’t an infinite resource – if you consume it at a high enough rate, it will run out. This is what NASA warns is already happening in the Middle East, where due to overconsumption and bad water management, an amount of freshwater almost the size of the Dead Sea […]

Researchers design software which they claim prescribes better treatment than doctors

Two researchers from Indiana University have developed a computer model they say can identify significantly better and less-expensive treatments than can doctors acting alone. If true, this research could have a significant impact on the healthcare system, but at the same time, rises some extremely important questions. The idea Casey Bennett and Kris Hauser had […]

Melting permafrost releases dangerous levels of CO2

Everything is connected on our planet; things you do on one side have completely unexpected but related effects on the other, and there is nothing truly isolated. Here’s a good example of just that: For most of the year, the Arctic is frozen. Hard ice and tundra is all you’re going to see there most […]

Researchers use computer program to reconstruct ancient languages

The Rosetta Stone may actually come in the form of a computer – one that can speak virtually any language, if programmed well enough. Languages have evolved, changed, adapted, mingled, disappeared – they’re way more dynamic than you would think; and for some of them, we have really limited information to study them on. This […]

MIT cell circuit has its own memory

MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, encode them in the cell’s DNA and pass it on for generations to come. Biotechnology The circuits, which are described in Nature Biotechnology could have a swarm of appplications, most notably long-term environmental sensors, efficient […]

Men's friendship with women driven by sexual attraction, study finds

The long debated idea of women and men being ‘just friends’ has been given a serious blow, as a new study suggests that men’s relationships with their female friends may be fuelled by an undercurrent of sexual attraction regardless of whether they are single or not; the feeling, however, is not mutual. University of Wisconsin […]
