Conclusion: under realistic conditions, the risk of contracting SARS-CoV-2 from cash is very low. |
| Remember more by taking breaks Posted: 29 Jul 2021 09:20 AM PDT We remember things longer if we take breaks during learning, referred to as the spacing effect. Scientists gained deeper insight into the neuronal basis for this phenomenon in mice. With longer intervals between learning repetitions, mice reuse more of the same neurons as before -- instead of activating different ones. Possibly, this allows the neuronal connections to strengthen with each learning event, such that knowledge is stored for a longer time. |
| Study tests microplasma against middle-ear infections Posted: 29 Jul 2021 09:20 AM PDT Middle-ear infections are a common affliction in early life, affecting more than 80% of children in the U.S. Antibiotics are often employed as a first line of defense but sometimes fail against the pathogenic bacteria that can develop in the middle ear, just behind the eardrum. In a new study, researchers explore the use of microplasma -- a highly focused stream of chemically excited ions and molecules -- as a noninvasive method for attacking the bacterial biofilms that resist antibiotic treatment in the middle ear. |
