The question seems awkward but the counter-intuitive reality is always there to make Science far more interesting, as revealed recently by Hao Cao and collaborators . Today’s story is a good combination of intriguing observations and amazing […]
Science news with bad titles usually attract a lot of attention. A recent example is “The sound of an atom has been captured” ]. Laypeople must know that atoms do not emit sound.

Long extinct squirrel-like creatures hold clues to earlier mammal evolution Mammals may have evolved much earlier than previously thought, according to researchers who’ve been studying the fossils of squirrel-like creatures that date back about 160 million years to the Triassic Period. The creatures have mammalian features and are from previously unknown species of haramiyid, which […]
You have probably heard this sentence: “the brain is the most complex organ in the universe”. Let´s dive inside such assertion to get a deeper feeling. The human brain contains around 86.000 million of neurons distributed across a bunch of brain areas ( roughly 190 ). That´s one thing, not everything. Even more complex is […]
If you have a bike, most surely you will own a helmet too. If you fall off the bike your helmet might avoid some nasty head injuries, right? That looks pretty obvious… except that it isn’t. Lets start with a little bit of skepticism, and as straightforward as it seems, we would like some proof […]
