Mental health trusts in England are now to play a vital role in processing the huge number of citizens referred under the government’s counter-terrorism strategy, known as Prevent. A new policy announced in November by the Home Office means urgent psychiatric care will now be provided by mental health trusts to those people with psychological problems who are referred to Prevent. But this will remove them from a pipeline of support under a program called Channel, aimed at those suspected of radicalizing. No one could possibly object to the provision of mental health care to those in need. But on deeper inspection, the integration of mental health trusts within the Prevent strategy reveals profound confusion within counter-terrorism policies. And the move could give health professionals perverse incentives to actually refer patients with mental health needs to Prevent – because they think it might get them help quicker.

Biology and biotechnology have entered a digital age, but security policies around such activities have not kept pace. New research outlines how the evolving nature of biotechnology should sound alarm bells for new ways to keep life sciences assets safe. This could be from accidental cyber-physical breaches, or more nefarious threats.

In a speech later today, President Donald Trump will outline his administration’s national security strategy, which portrays the world as a more competitive arena for the great powers. The administrations of both George W. Bush and Barack Obama emphasized great power cooperation while focusing on emerging threats such as terrorism, disease, and climate change. “After being dismissed as a phenomenon of an earlier century, great power competition returned,” the new national security document says.

Survivors of a terror attack have an increased risk of frequent migraine and tension headaches after the attack, according to a study. “We know a lot about the psychological effects of terror attacks and other extreme violence on survivors, but we don’t know much about the physical effects of these violent incidents,” said the study’s author. “Our study shows that a single highly stressful event may lead to ongoing suffering with frequent migraines and other headaches, which can be disabling when they keep people from their work or school activities.”

Last Thursday, Argentinians woke up to a political earthquake as the federal judge Claudio Bonadio, who investigated the role of the government of ex-President Cristina Fernández de Kirchner in covering up Iran’s involvement in the 1994 bombing of the Jewish community center, indicted Kirchner, Foreign Minister Hector Timerman, as well as other government officials. Experts argued that the treason charge brought against Kirchner and a number of her top aides vindicates the late Alberto Nisman’s investigation into the 1994 AMIA bombing.

Canada’s spy agency, CSIS, recently revealed that 60 foreign fighters who joined ISIS and other terror groups in Syria and Iraq are now back and living in Canada. Their fate has sparked fierce debate in Canada’s Parliament between Prime Minister Justin Trudeau and Conservative Leader Andrew Scheer. Scheer has expressed concerns about the national security threat posed by these fighters, while Trudeau pledged to prosecute those who broke Canada’s anti-terrorism laws. Despite the sensitivity of the issue, especially when the safety and security of Canadian citizens are at stake, Trudeau’s approach could therefore be deemed the most effective and efficient. The Conservative approach, meantime, not only indicates a “once a terrorist, always a terrorist” mindset, it also capitalizes on fear and stigmatization of Muslims, and does little to resolve the issue of homegrown radicals.

Anthropologists have debated for decades whether humans living in tribal communities thousands of years ago were more or less violent than societies today. Researchers wonder whether the question of more or less violence is the wrong one — what if it’s a matter of scale? In a new paper, the researchers present data showing that the size of a society’s population is what drives the size of its “war group,” or number of people of fighting age who defend it. They also show that the size of the war group is what determines the number of casualties in a conflict.

An Argentinian judge on Thursday ordered the arrest of the country’s former president Cristina Fernández de Kirchner, accusing her of covering up Iranian involvement in the 1994 bombing at the Buenos Aires Jewish center that killed 85 people and wounded 300. The former president, who now serves as a senator, is accused of signing a 2012 deal with Iran that would have allowed senior Iranian officials implicated in the attack to be investigated in their own country, rather than in Argentina.

The May 2017 Manchester Arena bombing could have been prevented, a report by the former Independent Reviewer of Terrorism Legislation has revealed. David Anderson QC’s report suggests there were opportunities to reopen the case, raising the possibility the attack could have been stopped. Newspaper headlines, however, are misleading, neglecting the nuance in Anderson’s report that the decision to ignore or misinterpret the intelligence on Abedi was “understandable” in the circumstances, overlooking the complex nature of counter-terror investigations. So, could the Manchester bombing really have been prevented?
