A new analysis explains why, as President Donald Trump goes past his first year in office, the pronounced, decades-long expansion of U.S.-based hate groups has slowed to a crawl during the first year of his administration. “[H]ate groups tend to grow in response to threats emerging from environments where social groups perceive their standing to be uncertain or at risk,” says an expert on hate-based social movements. “Hate incidents, in contrast, are most likely to rise primarily in response to expanding opportunities to act. Whether perpetrated through established extremist organizations or by free-standing adherents, such actions are most likely when those who desire to commit them perceive lower costs or risks.”

The substance used on 4 March to injure an ex-Russian spy ad his daughter was a nerve agent – but the British police say it was rarer than sarin or VX nerve agents, thus making the involvement of Russian state labs in the production of the substance certain. A spokesman for British Prime Minister Theresa May said the attack on Skripal and his daughter was an “appalling and reckless crime.” Skripal’s son Sergei, 44, died on a visit to Russia last year under mysterious circumstances.

The sudden illness in Britain of a Russian former spy has drawn comparisons with another poisoning in the United Kingdom – the 2006 assassination by Vladimir Putin’s agents of Russian former-spy-turned-Kremlin-critic Aleksandr Litvinenko. In using various poisons – some of them esoteric — to have his critics and adversaries killed inside Russia and abroad, Putin is continuing a storied KGB tradition. Here is a closer, if brief, look at some of the poisons Russian government agents have used on their lethal missions.

German ecoterrorists are the main suspects in an acid attack on a German energy executive, which has left him badly injured. Bernhard Günther, the CFO of energy giant RWE’s green subsidiary, Innogy, was struck as he crossed a park in Haan, a well-to-do suburb of Düsseldorf, on Sunday. Left-wing groups – the most famous one the Rote Armee Fraktion (aka Baader-Meinhof group), which was active in West Germany from the early-1970s to the mid-1980s – have attacked and killed a score of German business people in the last four decades.

Mary Shelley was 20 when she published “Frankenstein” in 1818. Two hundred years on, the book remains thrilling, challenging and relevant — especially for scientists like me whose research involves tinkering with the stuff of life. Talk of “engineering biology” makes a lot people squeamish, and technology can turn monstrous, but I read Mary Shelley’s “Frankenstein” not as an injunction against bioengineering as such. Rather, the story reveals what can happen when we – scientists and nonscientists alike – run away from the responsibilities that science and technology demand. Victor Frankenstein was certainly careless and perhaps a coward, unable to own up to the responsibility of what he was doing. We now know that science is best conducted with humility, forethought and in the light of day.

While President Donald Trump has not shied away from offering suggestions on how to prevent school shootings – including one controversial idea to arm teachers – what often gets overlooked in the conversation is research on the subject that has already been done. This research includes one major study of school shootings conducted in part by the very agency charged with protecting the president of the United States himself - the U.S. Secret Service. Has this research been ignored or just forgotten?

After the Arab Spring, North African countries experienced growing instability, and jihadist groups capitalized on both social unrest and local conflicts. As these groups strengthened, jihadists expanded their operations into the Sahel, and were able to propagate their transnational ideology to new audiences. The threat that jihadist groups in Africa pose to Western interests has grown over the past decade, as groups operating in North Africa, the Sahel, West Africa, and the Horn of Africa have honed their capabilities. Different terrorist organizations in these areas launched 358 attacks against Western targets and interests between January 2012 and October 2017.

“The right-wing terrorist threat is more significant and more challenging than perhaps the public debate gives it credit for,” the U.K.’s counterterrorism chief has said. “There are many Western countries that have extreme right-wing challenges and in quite a number of those the groups we are worried about here are making connections with them and networking,” he said, declining to give further details. Last year the British authorities foiled ten Islamist and four far-right terrorist plots.

Julius Caesar is said to have stated “alea iacta est” (the die is cast) as he led his army across the Rubicon river, triggering a point of no return in Roman history. In many ways, the horsepox synthesis, published by two Canadian scientists last month, is considered a new Rubicon for synthetic biology and the life sciences. Experts say that now that we’ve ventured across the river, it seems that we may be learning more about dual-use research in general. One expert notes that “Beyond the immediate issue of whether the horsepox work should have been performed (or published), the horsepox synthesis story highlights a more general challenge facing dual-use research in biotechnology: the unilateralist’s curse.” Research unilateralism contains an “action bias”: Horsepox synthesis is more likely to occur when scientists act independently than when they agree to a decision as a group.
