Ancient Phoenician’s genome sequenced A Phoenician who lived 2,500 years ago near Carthage had European ancestors, according to researchers who sequenced his mitochondrial genome after collecting DNA from his remains. The Phoenician’s ancestry was traced back to the European haplogroup U5b2cl, connected to the North Mediterranean and possibly the Iberian Peninsula. Seeker Protein linked to […]

Hubble image offers detailed view of Mars A detailed image of Mars has been taken by the Hubble Space Telescope as the Red Planet moves into opposition with Earth. The image depicts many of Mars’ geological features, such as mountains, plains and ice caps. Mars is in opposition today! Space.com Urban bees mostly dine on […]

Prion diseases are a group of severe conditions that affect the nervous system of many animals, including humans. Although their causes were highly controversial, there is a widespread agreement nowadays that they are originated and transmitted by prions, infectious agents with a normal and an abnormal structure. The abnormal prion protein infects the host animal […]

Blood from donations is separated into three components: red cells, platelets and plasma, and one component or another is then transfused into patients according to their needs. The conditions for storage differ for each component: red cell concentrates can be kept for up to 42 days at temperatures of 1-6ºC. Platelet concentrates (PC) are stored […]

Earth-sun magnetic field interactions seen by NASA space probes Explosive storms spawned by interactions between the magnetic fields of Earth and the sun can endanger satellites, spacecraft and astronauts in space, as well as power grids on Earth. Now, a fleet of NASA spacecraft has for the first time directly witnessed the mysterious way in […]

Silicon surfaces of crystalline solids are part of conventional electronics, but their exploitation in novel materials combining two-dimensional electron states (2DESs) and magnetism, which play an important role in the development of next-generation electronics, still remains elusive. The appearance of 2DESs at surfaces or interfaces and their interplay with magnetic degrees of freedom may open […]

Venus flytraps’ predatory ways may have roots in defense The genes that allow Venus flytraps to be carnivores may come from defensive mechanisms carried over from their non-insect-eating ancestors. Researchers found that gene expression patterns shift radically when prey steps into the plants’ traps, signaling digestive enzymes along the same protein paths used to help […]

Amplifying Voltage If we place a large resistor in a circuit containing a transistor we can amplify the incoming voltage, since according to Ohm’s law voltage is equal to current times resistance. So a current crossing a small resistance corresponds to a small voltage. But if the same current is made to cross a much […]

Author: Leire Gartzia Rivero got a Chemistry degree and completed her Master studies in “New Materials” at the University of the Basque Country. She holds a Ph.D. in Materials Science and Technology obtained at the same university, in the Molecular Spectroscopy Laboratory, where she focused on the spectroscopic characterization of photoactive nanomaterials based on energy […]

Nonhuman primates may be involved in Zika transmission Scientists who collected biological samples from 15 wild marmosets and eight pet capuchin monkeys plus one free-ranging capuchin in Brazil found four marmosets and three capuchins had been infected with the Zika virus. The Scientist Cosmic-particle technology opens window into Bent Pyramid New cosmic-particle technology has allowed […]
