Kathleen McKenna of The Boston Globe writes that Professor Alexander Rich, whose research confirmed DNA’s double-helix structure, died at 90 on April 27. Shuguang Zhang, associate director of the Center for Biomedical Engineering at MIT, said that Rich was “warm, wonderful, and open-minded.”
Washington Post reporter Martin Weil writes that Prof. Alexander Rich, who was known for his work with molecular biology, passed away on April 27. Rich’s work on hybridization, the pairing of two single strands of DNA or RNA, “is regarded as integral to creating much of modern biotechnology, with applications in diagnostics, forensics, genealogy and gene sequencing.”
Prof. Alexander Rich, a noted biophysicist known for his work investigating the structure of DNA and RNA, died on April 27, writes Denise Gellene for The New York Times. “I can think of no one else who has made as many major contributions to all facets of modern molecular biology,” said University of Maryland Prof. Robert C. Gallo.
Kat McGowan of The Scientific American cites research by Professor Angelica Amon that indicates recent findings may overestimate the amount of genetic variation in healthy human bodies. “Having the wrong chromosome number is not a good thing,” says Amon.
“There are now 108 known places in the genome which point us towards genes that are involved in causation. And, as you suggest, while most are in the nervous system, some of them, very intriguingly, point to the immune system as being involved,” Dr. Steven Hyman says of the new findings on schizophrenia during an interview with the PBS Newshour.
