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. Quantum acoustics study the propagation and the interaction of phonons, the analogues in sound to photons in light. An atom cannot emit […]

Antarctic ice growing at record-setting pace Antarctic sea ice is on track to reach a record high this month while Arctic ice has decreased to its sixth-lowest level, according to the National Snow and Ice Data Center. Antarctic ice usually reaches its maximum level each September, about the same time as the Arctic reaches its […]

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 […]

Coffee genome offers insights on why caffeine is produced Scientists have cracked the genome of Coffea canephora, one source of coffee beans, to gain insights into how caffeine evolved and why plants make it. A study published in Science details the complex evolution of caffeine in coffee and the ways in which that differs from […]

Every single day, the scientific knowledge of the biodiversity of the planet is increased with the description of new species. All of them are, in their own terms, valuable: a new piece in the puzzle of the history of Life on Earth. Most of the times, the new species can be easily classified together with […]

Spitzer detects proto-planetary collision near new star Evidence of a proto-planetary collision 1,200 light-years away has been seen near a young sun-like star by NASA’s Spitzer infrared space telescope. Scientists detected a significant change in the infrared radiation emissions from dust around the 35-million-year-old star, known as NGC 2547-ID8, in the constellation Vela. Discovery News […]

Bottles, bags, toys, clothes, prostheses… plastic is everywhere. Its global production has reached the quantity of 288,000,000 tonnes in 2012 . Day to day and year after year we only manage to get rid of a fraction of it by recycling, reusing or storing it in dumps but, sadly, some of that plastic ends up […]

Ancient star holds evidence of one of its earliest ancestors Traces of one of the universe’s first stars may have been found in the chemical signature of another ancient star that gobbled up material from the earlier star’s supernova. SDS J0018-0939, a star found in the halo around the Milky Way about 1,000 light-years from […]
