Researchers tracking older men have found an association between the loss of the male-only Y chromosome in blood cells and higher likelihood of Alzheimer’s diagnosis.
Dr. Chris Lau, Professor, Department of Medicine, University of California, San Francisco: "Although informative, the study is preliminary in nature and only highlights the fact that the Y chromosome could serve important functions beyond male sex determination and sperm production. What exactly..."
Dr. Thomas Wingo, Assistant Professor, Emory University School of Medicine: "The hypothesis is intriguing but I am left with a number of unanswered questions. Any single test is probably not going to be a realistic biomarker for..."

The National Academies has published a wide-ranging report on the impact of genetically engineered crops, recommending U.S. regulations should focus on individual products, not the process by which they were made.
Dr. David Stern, Professor and President of the Boyce Thompson Institute for Plant Research: "The NAS report is timely and wide-ranging, yet provides few definitive conclusions to satisfy a contentious scientific and social context..."
Dr. Wayne Parrott, Professor, Department of Crop & Soil Sciences, University of Georgia: "The inescapable conclusion, after reading the report, is the GE crops are pretty much just crops..."

A project that would synthesize a complete human genome and test it in cells within 10 years was discussed at a meeting of scientists, ethicists, lawyers, and entrepreneurs at Harvard University on May 10. Commentators raised concerns that the meeting was closed to the press and public
Dr. Kris Saha, Assistant Professor of Biomedical Engineering, University of Wisconsin-Madison:"The idea of making a synthetic human cell is certainly an ambitious project. It’s a big leap..."
Dr. Sriram Kosuri, Assistant Professor, Chemistry and Biochemistry Department, University of California Los Angeles:"There are many challenges to chemically synthesize a complete human genome from scratch, so it's interesting as a thought experiment. Currently, our synthetic capacity, our design capabilities..."

A letter in Nature Biotechnology reports the rearing of two young dairy cows whose genomes were edited to make them hornless.
Dr. William Muir, Professor Genetics, Department of Animal Sciences, Purdue University: “This is very exciting for several reasons. First, it is possible to insert an important natural genetic difference causing hornless cattle in a very elite animal of high genetic worth in a short period of time..."
Dr. Willard Eyestone, Research Associate Professor, Reproductive Biology / Biotechnology, Virginia Tech: “Although these cattle have been in the works for some time, this is the first peer-reviewed paper to document that editing the genetic sequence responsible for horns does in fact yield ‘hornless’ or polled animals..."
