Mineral-rich Sahara Desert dust may feed bacteria in Bahamas Mineral-rich dust carried by wind from the Sahara Desert to the Bahamas may be providing sustenance to the islands’ bacteria, according to a study. Scientists tracked the iron and manganese in the dust to the Great Bahama Bank over a three-year period. The study suggests that […]
Modern societies are growing old and we should be proud of such great accomplishment. Substantial improvement in hygiene, health and nutrition has allowed mankind to even surpass a three-digit age. Leaving any further social consideration aside, seems obvious that life sciences will have to make a big effort to understand the so called healthy ageing […]
That the so-called “Mediterranean diet” is good to keep a healthy heart is well known. However, how the eating habits of this population help them to stay healthy is not fully understood yet. Researchers from the University of Cambridge in the UK have investigated the effect of lycopene , the substance that gives the red […]
Perhaps the most repeated words in the last few years when talking about graphene – since scientists Geim and Novoselov were awarded the Nobel Prize in Physics in 2010 for their groundbreaking experiments – are “the material of the future”. There are some risks regarding so many expectations about everything related to materials science, since […]

Gene-editing method could remove HIV from infected cells Scientists have found a way of eliminating HIV from infected cells. Using the CRISPR/Cas9 genome-editing system, researchers removed a fragment of the virus. “These properties may provide a viable path toward a permanent cure for AIDS, and provide a means to vaccinate against other pathogenic viruses,” they […]
Black holes are not only gravitationally attractive: they also capture people’s attention. Just mention these two words in a course of elementary astronomy or in a public conference and you will find most eyes wide open. Even though they are common in observational astronomy, their singular physics and their fantastic dimensions makes them earn a […]
The idea of a living fossil is rather intuitive. We think that a kind of organism deserves that denomination if it has been living in the planet during a very large period of time apparently without any change. A well known example of living fossil is the Ginkgo tree (Ginkgo biloba) because, although it is […]

This simple statement found in one of the songs of that LP was able to summarise the paradoxical essence of life: death. But leaving any philosophical meaning […]

Common traits in tame animals may be due to neural crest changes Genetic changes that may affect a group of embryonic stem cells known as the neural crest may produce a specific set of features in animals bred for tameness. Common features and behaviors in domesticated animals include patches of white fur, floppy ears, youthful […]
Of all the seven wonders of ancient times, only the pyramids of Egypt remain on their feet. The technical means Egyptians had that many years ago for building these huge structures were extremely limited, and that is the main reason for them being so fascinating: they could build them despite the huge technical difficulties they […]
