Some years ago, with a sudden and drastic reduction on the number of honeybees, scientists realized that if these insects disappeared it would be the end of agriculture as we understand it, as they are the main drivers of agricultural pollination in the US . But would we be able to replace these pollinators with […]

Quantum computing is one of the most interesting fields of study nowadays, both from theoretical and pragmatic point of views. A universal quantum computer can potentially solve certain problems, as factorizing numbers, much faster and with fewer resources than a classical one . This developing technology is based on the use of quantum mechanics as […]

Competing gravity of galactic clouds probably caused band of gas A gravitational tug-of-war between the Large Magellanic Cloud and the Small Magellanic Cloud may be responsible for the huge ribbon of gas at the halo of the Milky Way. Astronomers in the U.S. and Germany measured how much oxygen and sulphur there is in the […]

“Junk” DNA in plants not needed to remain healthy So-called junk DNA is just that — junk, according to a study by researchers at the University of Buffalo in New York. In a study of the carnivorous bladderwort plant, they found that the part of the genome not responsible for coding proteins in plants is […]

Maples rely on wind, upward currents, and gusts to spread their seeds over long distances that can reach several kilometers. Maple seeds are able to autorotate because their center of gravity, determined by the position of the nut, is located at the base of the wing-shaped seed. It has been observed that, despite their small […]

Pear-shaped nuclei in some atoms may help explain antimatter Researchers have used a particle accelerator called REX-ISOLDE at CERN in Switzerland to discover an atom with pear-shaped nuclei. The discovery could lead scientists to extend the Standard Model in physics and help to explain why there is more matter than antimatter in the universe. LiveScience […]

Cryptography is, beyond any doubt, an important technology. Keeping the privacy of communications has many applications in modern societies. For instance, being able to send a message, as your credit card number, with the confidence that no one will understand it if it is intercepted, is a basic assumption for electronic transactions. Also, nowadays and […]

Jamestown settlers turned to cannibalism to survive, bones show The scarred skull of a 14-year-old girl reveals that English settlers in Jamestown, Va., may have engaged in cannibalism to survive. A brutal winter in 1609 brought a food shortage, killing off 80% of the population. Marks on the girl’s skull and tibia are the first […]

Nowadays we are getting more and more accustomed to making use of new technologies shortly after they have been developed. We like the idea of immediacy and our wishes coincide well with the commercial interests of industry. Nevertheless, there is a field in which this immediacy is almost impossible: the medical sector. Unfortunately, there is […]

Malaria reduced by preserving biodiversity of forests Researchers at Brazil’s University of Sao Paulo found that malaria could be kept from spreading while still preserving the biodiversity of the Amazon rainforest. The traditional view is that clearing such forests curbed the spread of the disease. Using a mathematical model, researchers found that the parasite causing […]
