Smartphones aren’t just for selfies anymore. A novel cell phone imaging algorithm can now analyze assays typically evaluated via spectroscopy, a powerful device used in scientific research. Researchers analyzed more than 10,000 images and found that their method consistently outperformed existing algorithms under a wide range of operating field conditions...

New research suggests liquid water is present beneath the south polar ice cap of Mars. Now, a new study argues there needs to be an underground source of heat for liquid water to exist underneath the polar ice cap. The new research does not take sides as to whether the liquid water exists. Instead, the authors suggest recent magmatic activity – the formation of a magma chamber within the past few hundred thousand years – must have occurred underneath the surface of Mars for there to be enough heat to produce liquid water underneath the kilometer-and-a-half thick ice cap...

Research team clarifies the mechanism of gliotoxin, a mycotoxin from the fungus Aspergillus fumigatus. Scientists have now discovered how the fungus knocks out the immune defenses, enabling a potentially fatal fungal infection to develop. It is everywhere – and it is extremely dangerous for people with a weakened immune system. The fungus Aspergillus fumigatus occurs virtually everywhere on Earth, as a dark grey, wrinkled cushion on damp walls or in microscopically small spores that blow through the air and cling to wallpaper, mattresses and floors. Healthy people usually have no problem if spores find their way into their body, as their immune defence system will put the spores out of action...
