As bad as earthquakes can be, and we’ve recently had our fair share of earthquakes around the world, the tsunamis they generate can be even worse. When an earthquake has a significant effect in a body of water, it displaces large quantities of water – and it is that displacement which causes the huge waves […]
The French didn’t invent wine, no more than Colombians invented coffee or the Italians discovered tomatoes. But… who did? What is the actual homeland of this wonderful drink? After analyzing some limestone residue, archaeologists working at University of Pennsylvania claims to have found the earliest evidence of European winemaking. The 2,400-year-old stone is apparently a […]
Hydrogen is the most common element in the Universe. It’s the first element in the periodic table, and it has but one proton and one electron. Understanding how it behaves at very large pressures is crucial to our understanding of matter and the nature of hydrogen-rich planets. Under typical conditions, Hydrogen is a diatomic molecule […]
Just yesterday we were telling you about a change in diet 3.5 million years ago, modifying the way our hominid ancestors evolved and, in turn, how we evolved. Now, we’re moving a little closer to the present day – researchers calculating the barium levels in fossil teeth claim that they’ve found a difference in the […]

A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles, similar in many ways to a fundamental particle postulated by Paul Dirac in 1931. Monopoles and Dipoles Until now, a magnetic monopole, the magnetic analogue to an electric charge has never been observed – all we had until now […]
To fully understand the processes and mechanisms that work at a cellular level, biologists should study them in their native, watery environments. But how would you go on doing this? Well, leave it to engineers to solve everyone’s problems – they have now deviced a kind of atomic force microscopy that works on samples sitting […]
One big obstacle scientists face in their efforts to develop effective drugs against HIV is the virus’ capsid – an outer cell membrane-derived envelope and an inner viral protein shell that protects HIV essential proteins and genetic information. Current drugs have a hard time breaching this structure, however this might change. Using a supercomputer that crunched immense […]
It seems like every week there’s a new study that hails a new wonder property or fantastic application for graphene. Is it truly the material of the future that will catapult technology to the next level? Seems like it. For instance, scientists at Nanyang Technological University (NTU) in Singapore used graphene as the basis for a novel […]
New analysis of fossil teeth from extinct fossils has shown that human ancestors greatly expanded their diets 3.5 million years ago, moving on to eat grasses and also other animals. Before this, the humanlike creatures (hominis) ate a forest based diet, pretty similar to what chimps and apes eat today. Researchers from the California Academy […]
Despite the fact that triceratops are some of the most well known dinosaurs, finding a complete skeletons is an extremely rare treat. It was one of the last non-avian dinosaur genera to appear before the Cretaceous–Paleogene extinction event – the extinction which caused the end of dinosaurs and the Mesozoic. The scientists from the Black […]
The only two (significant) places in our solar system, that we know of, which can create opals are Central Australia and Mars, so by studying the geologic processes which led to the creation of these minerals in the first place, we can perhaps find out more about the Red Planet. As a geologist, I was […]
We’ve written a great deal about schizophrenia in the past, mostly reports about new theories pertaining to the development of the disease or new types of pharmacological treatments. A great deal of interest and efforts are being invested in battling this severe psychological disorder, since it affects so many people (as many as 1 in […]
Researchers have for the first time described an unique snail species that can only be found high on top Mount Kaputar in New South Wales, Australia. The snails exhibit an atypical coloring – fluorescent pink – and can grow as large as eight inches long, true giants by snail standards. Though Triboniophorus aff. graeffei […]
In terms of materials, graphene is definitely the hot cherry at the moment; it is basically a one-atom thick layer of the mineral graphite (carbon), with more such layers stacked together forming crystalline graphene. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams, but also very durable and has a number of […]
“Eat, drink, and be merry for tomorrow we die” – seems to be the motto at big oil companies.

He concluded that cutting down on carbon emissions […]
Every living being is important, however in a transnational-based society everything has a price label on it, even humans. A recent study, for instance, has assessed the economic value of sharks, both alive and dead. The researchers involved in the study found that shark ecotourism currently generates more than US$314 million annually worldwide and is expected […]
The Brazilian rain forest is a home to a slew of birds of all shapes, sizes and coloring – some 1,700 species to be more precise. One of such bird is the goofy looking toucan, which can be easily recognized by its extremely long beak which can reach half the size of the bird’s body. Human […]
Turtles are maybe the most majestic creatures in the reptile world, and have always been a source of inspiration for man. Everybody knows the fable of the turtle and the hare, which teaches how slow, but sturdy and resilient strides can outwit inconsistent sprints. The turtle’s really serious about it, and as evidence it practices […]
Detailed analysis and review have confirmed the scientists’ initial opinion – the pebble containing slabs Curiosity stumbled upon last year were indeed part of an ancient streambed. When the Curiosity rover landed on Mars, it was expecting to find lots of things – but finding evidence of ancient water so close to the land site […]
NASA’s GRAIL mission had been studying the Moon’s gravitational field for 9 months, with great results – they have discovered the massive regions which cause irregularities in the Moon’s gravitational field, making it uneven. Planetary gravitational fields The Earth, the Moon, and pretty much all planets have irregular gravitational field – first of all because […]
Black holes are the single most interesting and puzzling objects in our Universe – that we know of.

Paleontologists working at Ohio University have unearthed evidence of two new species of ancient primates, named Rukwapithecus fleaglei and Nsungwepithecus gunnellifa, which offer solid evidence of a split between Old World monkeys and apes. Geological and paleontological analysis have shown that the fossils are approximately 25 million years old, which puts them in the late […]
Usually, species are named after defining trait, or sometimes, more rarely, after somebody famous in the field, but every once in a while, they get some rather cooky names – like is the case with Kooteninchela deppi. Cambrian and scrissors Pronounced Koo-ten-ee-che-la depp-eye, the 505-million-year-old fossil is a distant relative of lobsters and scorpions, and […]
Serving as one of the strongest metaphors nature has to offer, at the later stages of its evolution the caterpillar - a soft bodied, not very pretty, ground based insect - morphs into a butterfly - a majestic flying insect of varying coloring and shape. What exactly goes inside the chrysalis the caterpillar wraps itself with for the many weeks required for metamorphosis remains a mystery, though.
The life expectancy gap between men and women is a rather attested fact, and while in the past a laborious, physically tense lifestyle for men was used to serve as an explanation, in our day and age of gender equality this doesn’t quite cut it anymore. Researchers in Japan might have stumbled across a clue […]
