Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they ve been extremely difficult to detect until now.
Using what they describe as a chemical nose, UC Riverside chemists are able to smell when bits of DNA are folded in unusual ways. Their work designing and demonstrating this system has been published in the journal
Nature Chemistry. If a DNA sequence is folded, it could prevent the transcription of a gene linked to that particular piece of DNA, said study author and UCR chemistry professor Wenwan Zhong. In other words, this could have a positive effect by silencing a gene with the potential to cause cancer or promote tumors.

We have the opportunity for more targeted contact tracing, Hyde Park Superintendent Aviva Kafka said at a school board meeting Thursday. A few weeks ago, the consensus was we should continue with the approach we ve been using, since our approach was so successful . over the past few weeks we are hearing from folks they are rethinking that.
She said the plan, approved by the Dutchess County Department of Behavioral and Community Health and to be implemented after spring break, calls for quarantining students only when one of them comes within a six-foot radius of an individual who tested positive, rather than everyone in a given room or building.
