Don't Blame the Bird for Your Post-Thanksgiving Feast Snooze

Gigi Stewart | November 26, 2015 | Science
Tryptophan is involved in producing a brain chemical (serotonin) that can, in fact, make us sleepy. This is what leads to the conclusion that eating a lot of tryptophan-rich turkey on Thanksgiving makes our eyelids heavy. It seems simple. However, before we blame the bird, let's dig deeper for the facts.

Weekend Roundup: Now It's NATO vs. NATO (New Anti-Terror Organization)

Nathan Gardels | November 26, 2015 | World
The Turkish downing of a Russian jet that crossed into its territory while bombing targets in Syria complicates even further the play of contraries in an already bewildering set of Mideast conflicts. The episode introduces a fresh tension that could well pit NATO, of which Turkey is a member, against what Gopalkrishna Gandhi calls a fledgling new NATO, or New Anti-Terror Organization, that French President François Hollande is trying to organize globally in the wake of the Paris attacks. Hollande meets Russian President Vladimir Putin in Moscow this week. (continued)

4 Steps to Improve Ocean Conservation Research in Small Island States

Dr. Ayana Elizabeth Johnson | November 24, 2015 | Science
To be effective, marine conservation must be based on rigorous and targeted science. The large and growing threats to ocean ecosystems coupled with the limited scientific capacity of most small island states make science-based management not only an imperative, but also a challenge.

The Role of Believers at Paris Climate Change Summit

Luis Antonio Tagle | November 24, 2015 | Religion
Scientific studies on climate change are unequivocally telling us that the right to the environment is being violated, people are suffering greatly, and that it is time for an ecological conversion. The time is now to build new models of development that are climate compatible and lift people out of poverty.

This Scientist is Tackling What Could be the Largest Coral Reef Die-Off Ever

Ryan Duffy | November 24, 2015 | Impact
When we first met Dr. Ruth Gates this fall, she said something that really stuck with me. She told us that one of the problems with the scientific community is that "we can agree on 95% of something, and then debate the last 5% until it's too late to act."

Plugging Into Your Brain

Peter Diamandis | November 22, 2015 | Technology
Over the past few decades, billions of dollars have been poured into three areas of research: neuroprosthetics, brain-computer interfaces and optogenetics. All three areas of research are already transforming humanity and solving many of the problems that seem to have stumped our natural evolutionary processes.

Gaga for Gravitation

David Kaiser | November 23, 2015 | Science
Gravitation proved to be far more than its jumble of equations, nonlinear structure, and famous text-boxes. Though several newer textbooks have displaced the book from graduate students' syllabi, none has rivaled the book's cross-over appeal.

Weekend Roundup: Paris Attacks Upend Concepts of War, Security and Alliances

Nathan Gardels | November 21, 2015 | World
The attacks claimed by the self-described Islamic State in Paris have done more than spread fear across the West. They have upended our concepts of war, security and alliances in a connected yet disintegrating world -- a world in which no superpower or group of states can impose order. As the "End of Power" author Moisés Naím notes, ISIS has breached that perimeter that above all defines strong states: a monopoly over violence. It has shifted the battlefield to the soft targets of cafes and concert halls. As Lucia Annunziata writes from Italy, "The Third World War, whether you want to believe it or not, is already underway ... and Europe is its theater." The savvy of ISIS operatives has also called into question whether we can maintain both open borders and encrypted cyberspace. They have shown that distributed networks of angry youth at the margins of European society, who bond on the Internet instead of at the mosque, are beyond the reach of the drone strikes aimed at decapitating their leadership in the Mideast. As the Aspen Institute's Charlie Firestone writes in his analysis of the "guerilla cyber-warfare" declared by the Anonymous hackers against ISIS: "The Westphalian concept of sovereign nations dealing with each other as states has limited application to a world where networks are the dominant form of organization."
