Author: Teresa E. Gimeno is an Ikerbasque Research Fellow at The Basque Centre for Climate Change One of the expected effects of rising atmospheric CO 2 concentration in the atmosphere is an increase in plant water use efficiency. This is due to the expected enhancement of photosynthesis under future atmospheric CO 2 concentrations, together with […]
Uncertainties added to equation for alien life New research has included uncertainties of numbers in the equation used to determine how widespread alien life might be throughout the galaxy. “We can show that, given current scientific uncertainty, we get a distribution that could make both the optimists and pessimists happy at the same time: a […]
Many methods can be used to synthesise non-molecular inorganic solids. Some solids can be prepared by a variety of routes but others, especially those that are not thermodynamically stable, may be much more difficult to prepare and may require special methods. Non-molecular inorganic solids can also be prepared in various forms, as fibres, films, foams […]
From nucleic acids to proteins and sugar chains, all life is made up of polymers, large molecules made up of sequences of small units called monomers. However, how these macromolecules first appeared on the surface of Earth is still controversial. It is generally assumed that, right before life started, our planet was covered in very […]
Each of the Voyager probes, two unmanned spacecrafts launched in 1977, has a gold-plated audio-visual disc, a recording that aims to introduce us to a possible alien and to show the diversity of living beings and cultures that planet Earth has. Carl Sagan said that «The spacecraft will be encountered and the record played only […]
Researchers deliver cells to mice, zebrafish using tiny robots Magnetic microrobots about the width of a hair have delivered cells to preselected sites within living mice and zebrafish. Researchers say the technology may one day be used in cell therapy and regenerative medicine. The Scientist Survey locates previously unknown galaxy cluster A previously unknown galaxy […]

The wave nature of light expresses itself in the propagation all over space, showing an intrinsic limitation to be localized beyond the so-called diffraction limit which is of the order of half the wavelength of the photons propagating. However when interacting with matter, light often gets reflected, diffracted, scattered or absorbed depending on the interactions […]
Why people younger than 22 with congenital or acquired heart conditions should be more likely of developing a cancer? Actually, a small number of studies have been published, suggesting relatively high cancer incidence and mortality, compared to the general population. If it is true a correlation exists, there are several potential explanations. It could be […]
The concept of moduli space is of utmost relevance in theoretical physics and mathematics, especially in geometry, topology and string theory. A moduli space is, roughly speaking, a space that classifies a given class of objects modulo an equivalence relation # which identifies the objects in that we want to consider as equivalent or, more […]
Accepting asylum-seekers, migrants boosts nations’ economies An influx of migrants and asylum-seekers is beneficial to a country’s economy within five years. Researchers based their findings on 30 years’ worth of data collected from 15 Western European countries. Nature Shallow hydrothermal vents discovered near Azores Hydrothermal vents found off the Azores are not as deep or […]
