Sexual differences in the human brain, both in structure and function, have a high scientific interest and a clear social impact. In the biological part because of the different susceptibility of both sexes to some developmental disorders such as autism — four times more frequent in males than in females — , and also to […]
In our current understanding of the nature there still are some big gaps of knowledge that reminds us of the long journey ahead in physics. Here I will be talking about one of the great mysteries of our time in science, and the great endeavor taken by some of the most skilled people I’ve ever […]
Mature parasite living in fish eyeball helps host become easy prey for birds The parasite Diplostomum pseudospathaceum grows inside fish eyeballs and, depending on its age, either protects its host or compels the fish to become easy prey to birds. When the parasite is young, it wants its fish host to stay alive so it […]

The Pioneer plaques are a pair of gold–anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several […]
November 25, 1858, was a very cold day in Concord, Massachusetts. It was then that Henry David Thoreau discovered at Walden Pond some frozen fish he had never seen before, which were “shaped like bream, but had the transverse bars of perch”, as he wrote the following day. “Are they not a new species?” he […]
Every organism, from virus to animals need nitrogen (N) to live; indeed, nucleic acids and proteins are made out with N. Nearly all of these organisms, fulfill their nitrogen needs taken up N from the environment in reduced forms, usually as nitrate (NO 3 – ), ammonium (NH 4 + ) or amino acids. Interestingly […]
Early plate tectonics likely played role in Earth’s oxygen event The early days of plate tectonics may have contributed to the Great Oxygenation Event. “It was likely a combination of many of these mechanisms, including subduction, that allowed O2 levels to rise and be maintained for the rest of Earth’s history,” said study co-author Megan […]

Antimicrobial resistance is a complex problem that contributes to health and economic losses worldwide. Resistance to antimicrobial therapies reduces the effectiveness of current drugs, leading to increased morbidity, mortality, and health care expenditure. Because globalization increases the vulnerability of any country to diseases occurring in other countries, resistance presents a major threat to global public […]
In September 2015 a new scientific field was born. Two colossal experiment confirmed the existence of gravitational waves, measuring the ripple of space-time induced by two very distant black holes merging in a cataclysmic display of gravity waves and radiation . Gravitational wave astronomy was born then, much like neutrino astronomy was born with the […]
Diabetes is a disease typically associated with old age, especially when speaking of type 2, characterized for insulin resistance, and associated with obesity and therefore, more likely to occur in old age. A recent couple of papers published in Cell and Science Translational Medicine point to the healing potential of a fasting-mimicking diet for resetting […]
