A new era of solar observation: International team produces global maps of coronal magnetic field
Posted by Saúl Morales Rodriguéz in categories: mapping, space
For the first time, scientists have taken near-daily measurements of the sun’s global coronal magnetic field, a region of the sun that has only been observed irregularly in the past. The resulting observations are providing valuable insights into the processes that drive the intense solar storms that impact fundamental technologies, and thus lives and livelihoods, here on Earth.

Traces of antimatter in cosmic rays reopen the search for ‘WIMPs’ as dark matter
Posted by Saúl Morales Rodriguéz in category: cosmology
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is.

Mercury’s magnetic landscape mapped in 30 minutes
Posted by Saúl Morales Rodriguéz in category: space
As BepiColombo sped past Mercury during its June 2023 flyby, it encountered a variety of features in the tiny planet’s magnetic field. These measurements provide a tantalizing taste of the mysteries that the mission is set to investigate when it arrives in orbit around the solar system’s innermost planet.

People infer the past better than the future, study finds
Posted by Saúl Morales Rodriguéz in category: futurism
If you started watching a movie from the middle without knowing its plot, you’d likely be better at inferring what had happened earlier than predicting what will happen next, according to a new Dartmouth-led study published in Nature Communications.

Study suggests statistical ‘noise’ affects perceived evolutionary rates
Posted by Saúl Morales Rodriguéz in categories: evolution, existential risks
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that “younger” groups of organisms, in evolutionary terms, have higher rates of speciation, extinction and body size evolution, among other differences from older ones.
