Researchers from the University of Granada have investigated the daily changes in the expression of the so-called ‘clock genes’ (which regulate every cell in the body) among sepsis patients. »
Even though they are inanimate objects, sand dunes can ‘communicate’ with each other, researchers have found. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours. »
Using NASA's Hubble Space Telescope and a new observing technique, astronomers have found that dark matter forms much smaller clumps than previously known. This result confirms one of the fundamental predictions of the widely accepted "cold dark matter" theory. »
Scientists from the multidisciplinary research group ECsens of the University of Granada (UGR) have developed and tested a new system that enables a large number of chemical analysis techniques to be performed in situ, using a smartphone. »

Researchers at the University of Granada have analysed for the first time the link between sedentary time vs. objectively-measured physical activity levels and systemic concentrations of glycaemic, lipid, and inflammatory markers among pregnant women. »
Smoke particles from the fires ravaging Australia have traveled more than 12,000 km, crossed an ocean and a mountain range and arrived in South America, meteorological institutions confirmed, after smoke was detected in Chile, Argentina, Brazil and Uruguay. »
The mysterious disappearance of Greenland’s Norse colonies sometime in the 15th century may have been down to the overexploitation of walrus populations for their tusks, according to a study of medieval artefacts from across Europe. »
