There's so much you can do with a smartphone today - much more than just browsing the web or social media. When you can combine them in a network, however, the possibilities might be endless. For instance, researchers at Caltech and the United States Geological Survey (USGS) are working on an earthquake early warning system based on the collective data fed in by thousands of smartphones. Only a couple of countries in the world give vulnerable cities an early warning - often just enough time to hit cover and save your life - but smartphones are virtually ubiquitous all over the world, even in poor countries which lack basic infrastructure like roads or flushing toilets.
Astronomers have known for quite a while that Mars has distinct polar ice caps, but the Red Planet might also have belts of glaciers at its central latitudes in both the southern and northern hemispheres. These huge glaciers are covered by a thick layer of dust which masks them and makes them seem like they are actually part of the surface of the ground.
When tyrannosaurs ruled the world, no one was safe from them - not even other tyrannosaurs. The skull of an unfortunate adolescent tyrannosaur shows signs of brutal fight; the individual was defeated and then eaten by members of its own species, new research shows.
Most people tend to think of the Earth in terms of crust, mantle and core, and while those are indeed the largest "layers" (you can't properly call the mantle a layer though), each one of them is made from other, thinner layers. Now, researchers from the University of Utah have identified another one of these thinner layers, 930 miles beneath our feet.
Paleontologists have found the remains of a "super salamander" - a previously unknown car-sized species of early amphibian. The predatory salamander likely feasted on fish and even small dinosaurs.
Australian researchers have uncovered what might be the biggest impact asteroid impact zone in the world – at over 400 kilometers (250 miles)! Naturally, the crater isn’t visible today, but geophysicists have found the impact’s scars deep below the surface. Lead researcher Dr Andrew Glikson from the ANU School of Archaeology and Anthropology explains: “The two asteroids […]
Even as a geologist, I can’t help myself from looking at lava with an almost childish fascination — it’s something from the depths of the Earth (literally), with the potential to destroy anything in its path, and also to create new landscapes, drastically changing the surface of the Earth. In the short film above, Lance Page managed […]
Some 17 million years ago, a beaked whale took a wrong turn up an African river, something which ultimately proved to be its demise. But now, geologists studying the whale's fossils believe the whale's unfortunate end might shed a new light on early human evolution.
Some 480 million years ago the seven-foot-long Aegirocassis benmoulae swam in a shallow sea covering what is today the Sahara desert. This giant arthropod, much larger than arthropods existing today, was likely the biggest creature in the world at the time.
The Moon's geologic past was much more interesting and active than previously thought, results from the Chinese lunar rover indicate. The Yutu moon rover found evidence of at least nine distinct rock layers deep beneath its wheels, something which seems to indicate a more complex setting.
Deep inside the Earth, in the gigantic Hang Son Doong cave in Vietnam, there lies a completely unique and mostly unknown ecosystem. Using a GoPro-carrying drone, Beijing-based traveler Ryan Deboodt provides a unique insight into this cave, showing a pristine, forgotten world. The cave was only discovered in 1991, but even then, scientists had to wait until 2009 […]
If you've ever visited the McMurdo Dry Valleys in Antarctica, then you've likely had a surprise. The cold, frigid white background cut by snowless valleys is marked by the Onyx river, the continent's longest and largest river, which ends with a five-storey-tall waterfall that spills bright blood-red water over an enormous glacier.
An eruption from an underwater volcano in the Pacific 'Ring of Fire' caused a 1-km wide island to form.
The Sahara Desert and the Amazon area have few things in common - one is a dry, barren wasteland, while the other is the most fertile area on Earth. But according to a new NASA study, there may be more than meets the eye when it comes to the two - dust from the Saharan area makes the trans-Atlantic journey, fertilizing the Amazonian rainforest with phosphorus.
A magnitude 6.8 earthquake (initially 6.9) has struck Northern Japan earlier today, with a small tsunami striking the coast without any significant damage. The tsunami was on the order of tens of centimeters. There was some worry, despite Japan being one of the most well prepared countries in the world to deal with earthquakes. “Overall, the […]
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.
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 […]
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 […]
An underwater volcano that’s been spewing ash and lava for the past month just created a new island off the Tonga archipelago. The volcano, called Hunga Tonga, has since stopped erupting and the island might not be long lived. Mostly made of ash and formed around the crater of the volcano, the half-mile long island […]
According to a new study, water once flowed on the surface of Vesta, the second-largest asteroid in the solar system. This took astronomers by surprise, as no one was really expecting to find this.
Some fires are big enough to see from outer space, others burn for a very long time, but from what I could find, this is the oldest continuous fire in the world. Beneath an Australian mountain, a fire has been burning continuously since 4000 BC.
Aboriginals around what is today Melbourne have been telling a story for thousands of generations – a tale of waters rising after the ice age. Without using written languages, they passed it down orally, generation to generation, with surprising accuracy. Now, a new study concluded that the story is actually really accurate, despite being passed […]
The Permian was a geologic period that ended some 250 million years ago, with the largest extinction our planet has known. Geologists have now found evidence that global acidic rain accentuated or even caused the massive extinction.
A new study may have finally found where Earth’s water came from. There are currently two competing theories, with one claiming that our planet generated its own water geologically, while the other suggests that water was brought by icy comets or asteroids from outside. A new study concluded that most of the water we see […]
Hydraulic fracking is responsible for a swarm of earthquakes, one of which was felt by Ohio residents in March 2014, a study has found. While the earthquake hag a magnitude of only 3.0 degrees, it is believed that it may have activated a geological fault and may ultimately lead to more significant temblors.
A giant reptile which looked somewhat like a dolphin but had the behavior of a dinosaur was discovered around what is now the Isle of Skye, in Scotland. The predator, an Ichtyosaur lived 170 million years ago and its diet probably consisted of fish and invertebrates, but it may have also eaten sharks and even dinosaurs.
In March 2014, the US and Mexican governments decided to release a flow of water down the Colorado River, in an experimental attempt called “Minute 319”. The river has experienced record droughts in 2014, but surprisingly, this initiative reversed a 13-year decline in the greenness along the delta. The Colorado River stretches along 1,450-miles (2,330 km), encompassing seven […]
Do you fancy diamonds? If the answer is ‘yes’, then you’ll absolutely love this rock extracted from a Russian mine. The rock is littered with over 30,000 diamonds, something which is extremely rare and may yield valuable information about how diamonds form in natural conditions. What’s unlucky for gem sellers was very fortunate for researchers […]
If you have a geologist friend or family, then you probably know they’re an awesomely weird bunch. I’m a geologist myself, and even I find it hard to buy presents for another geologist sometimes – so this is why I put along this list – to give you an idea of some awesome stuff you […]
A rare 520-million-year-old fossil shaped like a ‘squashed bird’s nest’ has been discovered by a Chinese team of paleontologists. The team believes that the fossil, which is in excellent shape, will help us better understand how the Earth’s seas were like during the Cambrian.The fossil probably belongs to the ‘chancelloriid’, a group of bizarre, balloon-shaped creatures […]
New experimental research found that Saturn’s largest Moon, Titan, has much stronger winds than previously believed. These rogue winds actually shape the hydrocarbon dunes observed on its surface. Titan is, along with Earth, one of the few places in the solar system known to have fields of wind-blown dunes on its surface. The only other ones […]
A NASA probe has taken a picture of a surprising pie-like geological feature on Mars. Scientists are not yet sure what caused the feature, but the likely culprit is lava. The 1.2 mile (1.9 km) wide feature was imaged by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) appears like an island of iron in […]
It’s one of England’s better kept secrets – Old Sarum is a hidden gem among gems, one of the most spectacular ancient sites in Europe and in the world. Old Sarum is the site of the earliest settlement of Salisbury in England. The site contains evidence of human habitation as early as 3000 BC, but only […]
Evidence of ancient bony fish suggests that they copulated even though many of their descendants stopped doing so. Paleontologists believe this is the first-known animal to stop reproducing by spawning and instead mate by having sex. The primitive fish (Microbrachius dicki) measured about 8cm long and is now long extinct. As it often is today, the first sexual […]
It’s very small and incredibly old – scientists have found the egg of a 240 million year old parasite – a pinworm, to be more precise. It’s the oldest pinworm ever found, and one of the oldest evidences of parasitism ever found. The pinworm, also known as threadworm, is a parasitic intestinal worm, pretty common […]
Geologists are close to cracking the mystery of one of the biggest earthquakes in American modern history – the 1872 North Cascades event. Now, over one century later, they believe they have finally found the origin of the earthquake. An ancient mysterey Current research points to a newly discovered fault near the town of Entiat in Chelan […]
Dr Nick Longrich from Bath University was studying bones from two horned dinosaurs from the ceratopsian family (related to Triceratops), when he discovered that the two were actually previously unknown species. The findings highlight that dinosaurs in area were more diverse than previously thought, and they also show that sometimes, museum archives can yield surprising information. “We […]
Scientists have finally climbed to the bottom of one of Siberia’s mysterious holes, and they have come up with some interesting information – and some amazing pics. In case you’re not up to date, scientists started observing some mysterious craters in Siberia. The pseudoscience media had a field day – and so did conspiracy theorists. […]
For the first time in its mission to study Mars and the potential for life on it, the Curiosity Rover has identified a mineral. The rover took samples by drilling in a Martian mountain and was then able to make the identification. The mineral in case is called hematite. Hematite is an iron oxide (Fe2O3) […]
Fossil hunting can be exciting and highly rewarding, but sometimes, fossils are also found through a fluke. Jeff Dornbusch, a volunteer with the Truth or Consequences museum in southern New Mexico (a museum of local history and tradition), was taking a hike on his day off when he stumbled on what he initially thought was a pile […]
Intricate polygons on Mars could be a clear indication of a wet past for the Red Planet. Most crater floor polygons have diameters ranging from 15 to 350 m, and it’s still not clear how and why they appeared – though one theory seems to be gaining ground: the idea of former lake beds. Polygons […]
Hima Hassenruck-Gudipati graduated this year from Caltech. She majored in mechanical engineering but minored in geology and her main area of interest was seeing how green technology and engineering can help mitigate the effects of climate change. Now, she has embarked on a global quest to understand the past, the present, and the future of climate change. […]
A Yale undergrad may force us to rewrite geology and biology books, after reporting a find which suggests that life can exist much deeper than currently believed, at temperatures at which DNA is barely stable. Geologists found carbon isotopes in rocks on Washington state’s South Lopez Island; these isotopes suggest the minerals grew from fluids flush […]
Megalodon is quite possibly the most dangerous predator to ever live in the Earth’s waters in the recent geological history – roaming the seas between 28 to 1-3 million years ago. We’re still not sure why it went extinct, but a recent study suggests that its extinction paved the way for whales to grow more and more, […]
It was about as big as T-Rex, but not quite as fit – new fossils have revealed that Deinocheirus mirificus had quite a beer belly. “This is an entirely new body plan” for such dinosaurs, says Stephen Brusatte, a vertebrate palaeontologist at the University of Edinburgh, UK. Indeed, few scientists would have imagined such a scientific appearance. The […]
Geologists have known for quite a while that the Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field, like that of a bar magnet maintains the same intensity, but for unknown reason(s), it sometimes becomes weaker and changes polarity. Now, a new study has showed that this phenomenon could happen much […]
Scientists have discovered an almost rectangular feature consisting of ancient magma. The features are similar to rifts here on Earth, a linear zone where the Earth’s crust and lithosphere are being pulled apart. However, since the Moon doesn’t have any plate tectonics to cause rifts, the origin of this magma is still questionable. Magma on the […]
Some bizarre spherical fossils found in China may be remnants of some of the world’s earliest animals (not unicellular organisms). A recent analysis has revealed that they are not bacteria or single celled protists, but rather algae, or even embryos from early animals. “The real value of these fossils is that we now have some direct […]
A team of geologists from Iceland, Sweden and Saudi Arabia has found changes in groundwater chemicals prior to earthquakes. They emphasize that they haven’t found a precursor to earthquakes, but there seems to be a connection between these chemical changes and incoming earthquakes. There is no reliable earthquake warning system, and there almost certainly won’t […]
Europa, Jupiter’s icy moon is the only body in the Solar System found to have plate tectonics (besides Earth). A new study has found several defining features, including plate subduction, broken linear features and offset likely caused by strike slip faults. An introduction to plate tectonics Plate tectonics is one of the newest big theories […]
