An experiment at GSI simulates how heavy elements capture protons. Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). This occurs at extremely high temperatures, but at relatively low energies. An international research team headed by Goethe University has now succeeded in investigating the capture of protons at the storage ring of the GSI Helmholtzzentrum für Schwerionenforschung.

As the scientists report in the current issue of Physical Review Letters, their goal was to determine more precisely the probability for...

Potential risks and benefits. A unique Rutgers-led study found that overweight and obese older women who took more than 3x the recommended daily dose of vitamin D showed improvements in memory and learning – but also had slower reaction times. The researchers hypothesize that slower reaction times may increase the risk of falling among older people.

The researchers, whose work is in the Journals of Gerontology: Series A, used computers to assess the impact of vitamin D on cognitive function. The researchers evaluated three groups of women between 50 and 70 years old in a randomized controlled trial.

One group took the recommended daily dose of 600 international units (IU), equivalent to 15 micrograms, of vitamin D ...

Access to clean water remains one of the biggest challenges facing humankind. A breakthrough by engineers at The University of Texas at Austin may offer a new solution through solar-powered technology that absorbs moisture from the air and returns it as clean, usable water.

The breakthrough, described in a recent issue of the journal Advanced Materials, could be used in disaster situations, water crises or poverty-stricken areas and developing countries...
