Geologists press recognition of Anthropocene - Earth changing human epoch

We are living epoch changing times – literally. According to an influential and evergrowing group of geologists, there are more and more signs that we are living in an epoch that is like no other in the history of the Earth, and therefore it is required that we acknowledge it as so – the Anthropocene. […]

Seismologists charged with manslaughter for not predicting earthquake

Topping this week’s absurd news by far, this is one of the most preposterous things I’ve read in all my life. Seven seismologists are charged with manslaughter after they failed to predict the 2009 L’Aquila that made 300 victims. Earthquake prediction and other fairytales At the moment, and in the forseeable future, it is impossible […]

Fossil of Cambrian sea predator discovered - with video

Anomalocaridids were extremely weird animals, by today’s standards; but by the standards of the Cambrian, they were the hot guys. They had a long spiny head, powerful limbs which were probably used to snag prey and a series of blade-like filaments in segments across the animal’s back, which could have functioned as gills. During the […]

Amazing 49 million year old spider gets a 3D portrait

An extremely old spider has showed its face for the first time in almost 50 million years; buried in a large chunk of amber, this Huntsman spider has descendants which live in the tropics and Southern Europe today. They can grow up to 30 centimeters, but they’re not aggressive and not poisonous for humans, despite […]

Galileo reveals magma 'ocean' under surface of Jupiter's moon

New analysis from NASA’s Galeileo spacecraft shows that there is an ocean of molten (or partially molten magma) beneath the surface of Io, one of Jupiter’s moons. The finding was published today, May 13, in Science magazine. Volcanic Io Io is the most active volcanic object in our solar system, and this confirmation of a […]

Fool's gold is ocean's fertilizer

Bacteria and small plants at the bottom of the ocean require significant quantities of iron to survive and grow, just like us humans do. But their situation is extremely different, and they can’t just opt for an iron rich diet. So where does their iron come from ? Pyrite, or fool’s gold (as it […]

Exotic extreme microbes played a role in Earth's early atmosphere

Some species of bacteria can survive virtually anywhere: in acids, in nuclear waste, at extremely low or high temperatures, at extreme pressures, and so on; extreme microbes that survive on gases thrown out by Siberian hot springs may have played an extremely important role in the formation of our planet’s atmosphere and its composition, a […]

Geophysics shows plume of Yellowstone volcano is much larger than previously believed

Yellowstone is without a doubt one of the most fascinating places on the face of the planet. But it doesn’t only attract families or people who want to relax, but it attracts scientists as well, and among them, geologists and geophysicists hold a top spot. University of Utah researchers made the first large-scale picture of […]

First expedition inside a volcano

Volcanoes have fascinated human beings since the dawn of time; thankfully, now we know enough not to think of them as powerful earth/fire gods, but to understand them as the magnificent phenomena they are. However, there are still many things we still haven’t been able to figure out them, and even if we would have, […]

Massive earthquake hits Japan... again

The seismological events near Japan are far from reaching an equilibrium; a 7.4 or 7.5 earthquake on the Richter scale struck apan’s Miyagi Prefecture and its vicinity in northeastern Japan at 23:32 p.m. (1432 GMT) local Time Thursday, the Japan Meteorological Agency (JMA) said. The area is not so far away from the major 9.0, […]

Large earthquakes don't trigger others far away

Ever since the 9.0 earthquake in Japan, there has been a growing mainstream interest for earthquakes, which will probably fade away as time passes, only to be revived when the next big temblor strikes. However, the good news is that, even for a brief period of time, seismologic studies are given the attention they […]

The next big earthquake

The massive 9.0 earthquake was the last in a series that devastated countries across the boundary of the Pacific plate. Even Japan, perhaps the country who was the most prepared in the world for this kind of seismic activity, was hopeless in front of the temblor and the tsunamis it created. But after the earthquakes […]

Texas Boys find fossil gold mine

Fossil hunting is for anybody – no matter how old, or how knowledgeable; all you need is a little information and some basic equipment, and you’re good to go. For Andrew Carroll and Thomas Smith, two North Texas sixth-graders, it required even less. Their adventures started when they found a bone while off playing and […]

Quartz may be key to plate tectonics

Plate tectonics is one of the most important theories, from the point of view of its practical effects on society – just look at the earthquake in Japan, or the iminent one in California, for example. More than 40 years ago, a man named J. Tuzo Wilson published a paper in Nature, describing how ocean […]

New research overturns oldest evidence of life on Earth

It is generally believed, and taught in paleontology courses that the oldest evidence of life on Earth is 3.5 billion years old, and was found in Australia, thanks to some bacterial fossils. However, geologists from the University of Texas conducted a study that concluded that the tiny gaps in the Australian chert are nothing more […]

An earthquake wake up call -- to the US

You don’t get any country better prepared for an earthquake than Japan. They know they are at risk, they are prudent, they have the money, the technology, and the work force; and yet, when hit by an earthquake of this magnitude, no matter how well prepared you are, you are in for some massive trouble. […]

Disturbing time-lapse animation shows Japan earthquakes

The 9.0 (it seems this is the actual magnitude) earthquake that hit Japan on the 11th of March created an absolutely incredible number of aftershocks, some of which were pretty intense on their own. However, a few days before it, as stress built up the subduction area between the Pacific and North American plates, one […]

Quake moved Japan by at least 8 feet

The devastating seismic event that struck Japan is affecting the entire world, and even the entire planet. While smoke continues to rise from the catastrophic temblor, Japan seems to have moved 8 feet inland, or even more, according to the USGS. “That’s a reasonable number,” USGS seismologist Paul Earle told AFP. “Eight feet, that’s certainly […]

Small hilltop city becomes refuge for earthquake and tsunami survivors

In the aftermath of the earthquake that violently struck Japan and the tsunamis it generated, the small, industrial city of Hitachi emerged unscathed from what Prime Minister Naoto Kan has described as Japan’s “worst crisis since the Second World War”, making it somewhat of a refuge for the hordes of refugees that flooded from many […]

Magnitude of Japan earthquake takes scientists by surprise

It’s no mystery for anybody that the earthquake in Japan is one of the largest ever to be recorded in history, and it’s no mystery for anybody that Japan is an area with numerous seismic events, but the magnitude of this one exceeded greatly all expectations, even the most pessimistic one. The 8.9 magnitude (or […]

Brilliant picture shows tsunamis estimated heights

This picture, created by a computer model at NOAA displays the expected heights of the tsunamis created by the 8.9 earthquake in Japan (which may be “upgraded” to 9.0 – calculating magnitudes is a pretty delicate issue). Of course the largest wave heights are expected near the epicenter, off the coast of Sendai, Honshu, Japan. […]

Radiation Level at Fukushima nuclear plant is 1000 times over accepted level after earthquake

The damage caused by the 8.9 earthquake in Japan is far from being over – asa matter of fact, unfortunately, it may very well just be starting. The earthquake and the tsunamis it created cut down power supply throughout a major part of Japan, and so the cooling system of several power plants was unable to […]

Japan in more trouble after an explosion at a nuclear plant

The earthquake that occured yesterday near the coast of Japan, the 4th most powerful earthquake ever to be recorded, is causing even more problems, after the direct damage, the aftershocks, the tsunamis, and the fire tsunamis; this time, things can get way, way bigger and worse, and the disaster toll keeps rising. An explosion at […]

Further heartbreaking information about the Japan earthquake + info on threatened areas

The earthquake that struck Japan is much worse than original estimates ! The original 7.9 magnitude actually just got upgraded to 8.9, which makes it 10 times more powerful, and the 4th most powerful earthquake in the past 100 years. Sadly, reports of injured and killed people keep coming in, and will likely not stop […]

Mars Rover on the edge of a crater

The Opportunity Rover is one brave little guy – he managed to defeat even the most optimistic of predictions, functioning several years after its primary objective was fulfilled. But now, he is little more than a bluish speck on this picture of the Santa Maria crater on the surface of Mars, taken by the Mars […]

Massive 7.9 magnitude earthquake hits Japan, creates tsunami

It’s been a busy tectonic month, and things aren’t about to chill down. A massive 7.9 magnitude Earthquake has just hit the Northern coast of Japan, triggering a more than four meter tall tsunami that wiped down cars and other property along the coastline, but it’s still unclear how many people were injured or killed. […]

Cassini finds that Saturn Moon is a powerhouse

It’s been quite a while since we published anything about the Cassini mission, but that doesn’t mean it hasn’t been active. The information it keeps sending back to Earth is priceless, and at some points, totally surprising. This was also the case of the Saturn Moon Enceladus, which appears to give out much more heat […]

Stunning picture and video from the Kilauea Eruption in Hawaii

As I was telling you just earlier, the Kilauea volcano erupted, with a fissure throwing lava up more than 20 meters towards the sky in a dazzling display of volcanic power. The Hawaii eruption took place just after one of the volcano’s floors collapsed, thus creating the necessary conditions for lava to come out to the […]

Volcanic eruption in Hawaii

Hawaii isn’t all warm breezes, mojitos and surfing; it’s what geologists call a hot spot, one of the most active volcanic regions on the face of the planet, so it was little surprise when Kilauea erupted; after all, it is one of the most potent volcanoes in the world, being in a constant eruption since […]

Los Angeles way overdue for major earthquake

It’s time we face it, a big one is coming – and soon ! All the predictions point towards a major earthquake near the San Andreas fault in a short time, and Los Angeles will suffer the most of it. A recent study published in the Bulletin of the Seismological Society of America confirmed that […]

New drilling method opens vast oil fields in the US

Numerous oil fields that could become an extremely valuable resource in the US and in the world have been out of reach ever since they were discovered; but that is all about to change thanks to a new drilling method that is currently being developed. The new drilling could help reduce oil imports for the […]

Secrets of dinosaur footprints revealed, thanks to goldilocks effect

A groundbreaking research conducted by the University of Manchester showed that terrain thought to be ruled only by giant dinosaurs was shared by numerous other smaller species. Dr. Peter Falkingham made a very interesting discovery, showing that dinosaurs can create lasting footprints, but under the right circumstances, combined with the right animal weight. The research […]

T-Rex's reputation is restored - he was a hunter

The fascination with T. Rex goes back a really long time, and whether you're a world class paleontologist, or some average Joe who loved Jurassic Park, T. Rex was definitely on your mind at some point. The biggest and most fierce hunter there was - or was he ? Scientists have been debating his diet for half a century, with one side claiming it fed by scavanging, while the other one was defending the dinosaur as a fearsome hunter.

Evidence of new species of man found

Svante Paabo, the researcher whose work provided the basis for the Jurassic Park movies seems to have struck gold once again; this time it’s about a finger bone older than 30.000 years, found in the Altai mountains, that as far as DNA analysis has shown, belongs to no known species of humans. They also found […]

Rare Earth minerals to be mined from the seafloor

The next step in prospecting and mining has always been a subject of speculation and theories, ever since the days of Jules Verne. For decades, an idea that flourished more and more was to gather up potato-sized magnanese nodules, rich in nickel, cobalt and manganese, that are very valuable in large quantities. The problem is […]

Insects trapped in amber offer a precious glimpse on prehistoric bugs

Amber is not very common, but you can’t say it’s really uncommon either. Bugs in amber – that’s rare, but a huge “stash” such as the one that was found in India – that’s really something out of this world. The bug “collection” that was unearthed seems to suggest that the Indian continent was not […]

Meet the horniest dinosaur ever

Fossil hunters have recently unearthed the fossil remains of a species that can easily claim the title of the horniest dinosaur ever to be found. Kosmoceratops lived some 76 million years ago, in the warm and wet swamps of (what is today) Utah; but what’s really fascinating about him is the fact that he has […]

Whale fossil found at the San Diego zoo

Well this is definitely not your average fossil hunt, by any standards. The excavating team was doing it’s thing, just as in any other day, when they heard a weird scraping sound. Gino Calvano, a paleontologist at the San Diego Natural History Museum was nearby, heard the sound, and headed straight towards the point of […]

Carnivorous humpback dinosaur surprises paleontologists

About 125 million years ago, these hunchback dinosaurs roamed today’s central Spain, measuring approximately 6 meters and feasting off of smaller animals of all sorts. However, what’s really surprising about the dinosaurs is its “hump”, a body structure never before seen in dinosaurs. A recently exposed skeletal structure revealed some unique features that has researchers […]

Back when reptiles took on dry land

It was more than 300 million years ago that reptiles made tracks on earth. The exact moment when this happened is unknown, however; oh, and by exact moment, I’m talking about pinning it down to a couple million years (you gotta love geologists for their sense of time). So, a discovery of fossilized footprints was […]

3 million years inactive fault in Sierra Nevada may trigger quakes after all

The major fault in Sierra Nevada is believed to have been “quiet” for more than 3 million years has shown signs of becoming active and it is believed that it can trigger quakes that can reach magnitudes of up to 7. This comes as a rather unpleasant surprise to geologists, as well as the people […]

8 surreal natural landscapes

The Wave, Arizona The Wave is an astonishing sandstone formation that fascinates photographers and attracts numerous hikers every year. It formed in the early Jurassic (190 million years ago) when dinosaurs ruled the Earth and compacted through the years, calcifying in vertical and horizontal layers. The lovely curves we see today are a result of erosion […]

Triceratops and Torosaurus were in fact the same dinosaur

A recent study conducted by a Montana State University doctoral student and one of the world’s top paleontologists shed some new light on more than 100 years of thought regarding the dinosaurs known as Triceratops and Torsaurus. The general belief since the late 1800s was that they were two separate dinosaurs: Triceratops had three horns […]

Melt rises up 25 times faster than previously believed

Scientists have for the first time determined the actual permeability of the asthenosphere in Earth’s upper mantle, which is basically responsible for how fast the melt rises towards the surface of the earth, and the results were surprising to say the least. Researchers found that it actually moves 25 times faster than previously assumed, which […]

4 hottest volcano events of 2009

Boy 2009 passed quite quickly, but it didn’t go without a blast, that’s for sure ! I’m gonna show you some really amazing stuff that happened during 2009, most of which you probably have no idea of, and this is the first one from that series. 4th place (honorable mention): Mayon, Philippines It may have […]

Taking a look at the 'little ice age' of 1810

Global warming is one of the main concerns on everybody’s lips, causing more and more damage to the environment every year, sometimes in ways that seem hard to believe; everyday there seems to be a new report about something that went, is going, or will be going terribly wrong. However, in the early 1800s, the situation […]

The main types of quartz -- in beautiful pictures

Quartz is a hard mineral consisting of silicon and oxygen. It’s one of the most common minerals in the Earth’s crust There are several different types of quartz, including amethyst, citrine, milky quartz, rose quartz, or agate. –yes, all of those are essentially quartz, and they’re all beautiful. Let’s have a look at them. “Plain” […]

Rift in African desert will become ocean

In 2005, a huge 35 mile rift broke the Ethiopian desert apart and immediately led to geological claims that a new ocean was appearing there because two parts of the African continent were being pulled apart. However, the claims were quickly dismissed as being too controversial. However, a new study published in the latest issue […]

Missing flying reptile link found

An international team of researchers from the University of Leicester (UK), and the Geological Institute, Beijing (China) managed to identify a new type of a flying reptile that can prove to be a crucial step in understanding evolution, or at least a big part of it. Pterosauria was the general name given for flying or […]

Life had a big rebound following marine mass extinction event

In 1980, Luis Alvarez and his team shocked the whole world when they announced their theory that an asteroid impact that took place 65 millions years ago was responsible for the extinction of the dinosaurs and much of that time’s living organisms. Despite the fact that they delivered substantial evidence, there are still some minor […]
