Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. This eighth revised edition represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. Our latest report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

From Mississippi to California, a number of convictions based on bite marks are under appeal or are being overturned. Our 2009 report Strengthening Forensic Science in the United States found that bite marks could not reliably be used to identify an individual. Since then, a number of people convicted on the reliance of bite marks identifying them as the perpetrator have begun the process of appeals. Two such cases are currently in that process and a Virginia man’s conviction was overturned in April. Read more about these cases at:

Bullying has long been tolerated as part of growing up and a fact of life that children and adolescents sometimes must encounter at school or on the playground, and coupled with cyberbullying through social media platforms, it is now widely deemed a major public health problem. Our latest report details the significant short- and long-term psychological consequences for both the targets and perpetrators of bullying and calls for evidence-based policies and practices to prevent bullying and its harm.
Bullying has long been tolerated as a rite of passage among children and adolescents. There is an implication that individuals who are bullied must have "asked for" this type ...

NASA's Kepler mission has verified 1,284 new planets – the single largest finding of planets to date. Our reports develop a forward-looking portfolio of research that will provide the basis for recapturing the value of human spaceflight and once again place the United States at the forefront of space exploration for the global good.

Dr. Mary C. Waters will be giving the spring 2016 Henry and Bryna David lecture on Tuesday, May 3, 2016 at 5:00 p.m. at the National Academies of Sciences, Engineering, and Medicine's Keck Center in Washington DC. Dr. Waters will address the war on crime and the war on immigrants in the U.S.

The growth of mass incarceration and of undocumented immigrants has been proceeding along parallel tracks since the 1970's. In her talk, she will look at these two groups together; arguing that the U.S. has developed a new form of legal exclusion and discrimination.

While the event is free and open to the public, register today as space is limited.
