If highly repetitive gene-regulating sequences in DNA are easily lost, then that may explain why some adaptations evolve quickly and repeatedly.

Diagnosed cases of autism spectrum disorder (ASD) in California rose by 600 percent from 1990 to 2003. Irva Hertz-Picciotto, Ph.D., director of the Environmental Health Sciences Core Center at the University of California-Davis, published this statistic in the journal Epidemiology a decade ago.

The esteemed epidemiologist told the audience during the Jan. 8 NIEHS Distinguished Lecture that she and her colleagues have only been able to explain a third of the increase.

“No single factor accounts for all autism cases, nor is there one event or exposure that can be responsible for the rapid increase in diagnoses,” said Hertz-Picciotto. “Each child’s path to altered brain development may be different.” Her talk was hosted by NIEHS and National Toxicology Program (NTP) Director Linda Birnbaum, Ph.D.

WCIA: A general strike seems like a personally costly way to protest, especially if you just stop working or stop buying things. Why are they effective?

Recent research suggests that nonviolent civil resistance is far more successful in creating broad-based change than violent campaigns are, a somewhat surprising finding with a story behind it.

When Erica Chenoweth started her predoctoral fellowship at the Belfer Center for Science and International Affairs in 2006, she believed in the strategic logic of armed resistance. She had studied terrorism, civil war, and major revolutions—Russian, French, Algerian, and American—and suspected that only violent force had achieved major social and political change. But then a workshop led her to consider proving that violent resistance was more successful than the nonviolent kind. Since the question had never been addressed systematically, she and colleague Maria J. Stephan began a research project.

(CNN) — The north magnetic pole has been drifting so fast that it could be a problem for smartphone maps and navigation systems.

The pole has been the friend of navigators for millennia, beckoning compass needles from virtually every point on the planet. And unlike the geographic north pole, which is fixed, the north magnetic pole has been slowly migrating over time — moving across the Canadian Arctic toward Russia since 1831.

But its swift pace toward Siberia in recent years at a rate of around 34 miles per year has forced scientists to update the World Magnetic Model — used by civilian navigation systems, the North Atlantic Treaty Organization, and US and British militaries — a year ahead of schedule.

The scientists who developed the revolutionary gene-editing system known as CRISPR are improving it with new tools that make it work better.

Over the last decade, military theorists and authors in the fields of future warfare and strategy have examined in detail the potential impacts of an ongoing revolution in information technology. There has been a particular focus on the impacts of automation and artificial intelligence on military and national security affairs. This attention on silicon-based disruption has nonetheless meant that sufficient attention may not have been paid to other equally profound technological developments. One of those developments is the field of biotechnology.

There have been some breathtaking achievements in the biological realm over the last decade. Human genome sequencing has progressed from a multi-year and multi-billion dollar undertaking to a much cheaper and quicker process, far outstripping Moore’s Law. Just as those concerned with national security affairs must monitor disruptive silicon-based technologies, leaders must also be literate in the key biological issues likely to impact the future security of nations. One of the most significant matters in biotechnology is that of human augmentation and whether nations should augment military personnel to stay at the leading edge of capability.

Military institutions will continue to seek competitive advantage over potential adversaries. While this is most obvious in the procurement of advanced platforms, human biotechnological advancement is gaining more attention. As a 2017 CSIS report on the Third Offset found most new technological advances will provide only a temporary advantage, assessed to be no more than five years. In this environment, some military institutions may view the newer field of human augmentation as a more significant source of a future competitive edge.

Commentary

The crime scene was straight out of an Alfred Hitchcock movie. One hundred and fifty dead birds lay sprawled on the ground, fallen out of trees in a park in The Hague, The Netherlands.

The second such occurrence last autumn made Dutch citizens look up and wonder. With robust starlings turned upside-down at their feet, the usual suspects of disease, pollution, and foul play were dismissed.

When Google bought the advertising network DoubleClick in 2007, Google founder Sergey Brin said that privacy would be the company’s “number one priority when we contemplate new kinds of advertising products.”

And, for nearly a decade, Google did in fact keep DoubleClick’s massive database of web-browsing records separate by default from the names and other personally identifiable information Google has collected from Gmail and its other login accounts.
