Why racism is not backed by science As we gather more information about the genomes of more people a conclusion seems more and more evident: there is not such thing as race.

The ribosome may be a missing link in the evolution of life. This suggestive proposal has been published by Meredith Root-Bernstein, Oxford University, UK, and her father Robert Root-Bernstein, Michigan State University, USA, in the Journal of Theoretical Biology . Their hypothesis is that primordial ribosomes were self-replicating intermediates between the prebiotic world and the […]

There is a widespread concern about the increasing antibiotic resistance and the limited new drugs to treat infectious diseases, as discussed in a previous post . Consequently, the discovery of a new antibiotic active against a range of bacterial pathogens including Staphylococcus aureus has been greatly welcome, especially because no resistance to it has been […]

Neanderthals interbred with ancient Asians at 2 points in history Neanderthals interbred with the ancestors of Asians twice in ancient history, according to a pair of studies published in the American Journal of Human Genetics. The studies approached the same question from different directions, but came to the same conclusion, looking at why Asians have […]

In 2012, some amateur astronomers reported the sighting of an unheard-of event: what was then called a cloud at the Martian limb apparently higher than 200 km above the planet’s surface. Such report received some attention from the mass media, particularly at the internet, but went mostly unnoticed among the professional community. However, the Planetary […]

Mesozoic mammals more diverse than previously thought The discovery of two fossils dating back about 160 million years suggests an extensive ecological diversity among early mammals that coexisted with dinosaurs during the Mesozoic era. The two fossils are of a mole-like animal that lived below ground and a creature that lived in the trees, each […]

The human brain is one of the most intriguing pieces of Nature. Since science is science, or even before, the human being has tried to understand the reason for its existence. Studies of comparative anatomy and physiology in the context of evolutionary theory began to define it as a rarity in the natural realm. We […]

Most people in Spain have heard about the ongoing bitter polemic between the Victims of Hepatitis C Platform and the Spanish government with regard to the access to a new medication called Sovaldi approved by the Spanish government last 1st October. The main reason for such clash between them is simple: the asking price for […]

Sad as it may be, every star must die. At some point during its life it stops burning nuclear elements to sustain itself via radiation pressure, and collapses. Its ultimate fate depends on its mass; most of them are not massive enough to produce a supernova by themselves, but they die in an equally spectacular […]

Sea slug can use photosynthesis for nutrition by taking gene from algae The emerald sea slug steals a gene from the algae it eats, allowing it to get nourishment from photosynthesis. Discovery Chimps adopt new calls when moved to new groups Chimps who move into a new group change their calls to match those of […]
