Today, Wednesday, May 25, astronomers unveiled the most complete 3-D map of the local universe (out to a distance of 380 million light-years) ever created. Taking more than 10 years to complete, the 2MASS Redshift Survey (2MRS) also is notable for extending closer to the Galactic plane than previous surveys – a region that’s generally obscured by dust.

On August 17, 2017, scientists made history with the first direct observation of a merger between two neutron stars. It was the first cosmic event detected in both gravitational waves and the entire spectrum of light, from gamma rays to radio emissions. The impact also created a kilonova -- a turbocharged explosion that instantly forged several hundred planets’ worth of gold and platinum. The observations provided the first compelling evidence that kilonovae produce large quantities of heavy metals, a finding long predicted by theory. Astronomers suspect that all of the gold and platinum on Earth formed as a result of ancient kilonovae created during neutron star collisions. Based on data from the 2017 event, first spotted by the Laser Interferometer Gravitational-wave Observatory (LIGO), astronomers began to adjust their assumptions of how a kilonova should appear to Earth-bound observers. A team of scientists reexamined data from a gamma-ray burst spotted in August 2016 and found new evidence for a kilonova that went unnoticed during the initial observations.

Clinical trials for genome editing of the human germline – adding, removing, or replacing DNA base pairs in gametes or early embryos – could be permitted in the future, but only for serious conditions under stringent oversight, says a new report from the National Academy of Sciences and the National Academy of Medicine.

An international, multidisciplinary organizing committee has been appointed to plan the Second International Summit on Human Genome Editing, which will take place Nov. 27-29 in Hong Kong.

On the eve of the Second International Summit on Human Genome Editing, we were informed of the birth of twins in China whose embryonic genomes had been edited.

Carrie Lam, Hong Kong’s chief executive, welcomed hundreds of participants from around the world to the Second International Summit on Human Genome Editing, which began today.

In December 2015, the U.S. National Academy of Sciences and U.S. National Academy of Medicine, the Royal Society of the United Kingdom, and the Chinese Academy of Sciences hosted an international summit in Washington, D.C., to discuss scientific, ethical, and governance issues associated with human genome editing.

We thank the organizing committee of the Second International Summit on Human Genome Editing, held this week in Hong Kong, for planning an important and timely conference on a rapidly advancing area of science and medicine.

A new publication from the U.S. National Academies of Sciences, Engineering, and Medicine, provides a brief summary of presentations and discussions at the Second International Summit on Human Genome Editing, held in Hong Kong on Nov. 27-29, 2018.

A commentary published in Nature calls for a moratorium on clinical uses of heritable human genome editing and the establishment of an international governance framework.

An international commission has been convened by the U.S. National Academy of Medicine, the U.S. National Academy of Sciences, and the Royal Society of the U.K., with the participation of science and medical academies around the world, to develop a framework for scientists, clinicians, and regulatory authorities to consider when assessing potential clinical applications of human germline genome editing.

Last week, the International Commission on the Clinical Use of Human Germline Genome Editing held its first public meeting at the National Academy of Sciences building in Washington, D.C.

The International Commission on the Clinical Use of Human Germline Genome Editing is tasked with identifying the scientific, medical, and ethical requirements to consider when assessing potential clinical applications of human germline genome editing — if society concludes that heritable human genome editing applications are acceptable.

We recently launched a new website intended to highlight the science underlying questions that our research shows Americans have about current issues.

It has been a little over a year since the Second International Summit on Human Genome Editing in Hong Kong, where scientist He Jiankui (pictured above) announced the birth of twins whose healthy embryonic genomes had been edited to confer resistance to HIV.
