Joint oscillation of Jupiter, sun might detect gravitational waves The joint oscillation of the sun and Jupiter might hold the key to detecting gravitational waves. Oscillations from Jupiter in 2011 were detected in frequencies that matched the sun’s. Researcher Ibrahim Semiz suggests that the oscillations might have been caused by gravitational waves, and other researchers […]
Let’s start with a thought experiment. We are looking up to a starry night sky. What if we turn off every star in our Galaxy? The heavens would become much darker, but some light sources would still be working. The Moon and planets? Great, let’s turn them off too. Yet another Solar System phenomenon would […]

Some jellyfish species are beautifully fluorescent in the dark ocean, emitting light from different parts of their bodies in a process that is thought to help them to warn off predators. The molecular biology behind this process of glowing is possible thanks to one of the most famous proteins in molecular biology, the green fluorescent […]
In some beaches of Madagascar you can find in the sand, if you are lucky, fragments of egg shells that seem oddly large. They used to be, in fact, part of huge bird eggs, massive as watermelons (and able to become the most memorable omelet ever), laid by the avian titans: the extinct elephant birds […]
Planck data back standard cosmic evolution model, shake up dark-matter theories Data collected by the European Space Agency’s Planck space observatory have resulted in a detailed full-sky survey of the cosmic microwave background, the remnants of radiation left behind by the Big Bang 13.8 billion years ago, reaffirming the standard model of cosmic evolution. However […]
If in the two previous entries of this series we have seen that (contrarily to what Dembski’s filter suggests and needs) ‘law’ and ‘hazard’ are not different types of explanations, but necessary and complementary elements of basically all explanatory models, I will try to show here that ‘explanation from purpose’ is not as significantly different […]
The Unknown Continent, t he White Desert. In the past only few -and brav e- people, such as Shackleton, Amundsen or Scott, dared to explore Antarctica. Nevertheless, in the fifties scientists started thinking that it was a very interesting place for doing research, due to its unique conditions, and started building more and more stations […]
Although not the most important among the many different animals studied by Charles Darwin during his amazing journeys on board the Beagle, the little finches from the Galápagos Islands have become one of the most popular representatives of Darwin’s theory of natural selection. They embody the process of speciation forced by environmental conditions, in the […]

Hummingbird flight similar to that of insects Scientists recorded a hummingbird as it hovered then created a 3D model to assess the airflow patterns created by the flapping of its wings. While other birds use the downstroke of their wings to fly, hummingbirds use upstrokes and downstrokes to create small vortices that merge into one […]
Imagine there is another world in the universe similar to the Earth, where there are mountains, rivers and seas. There are also winds, volcanoes, clouds and rains… science fiction, no, such a world does exist and not too far from the Earth if one considers the scale of the universe. This is the largest moon […]
