  • Information Technology Can Save Police Lives

    Police officers face well-documented risks, with more than 50,000 a year assaulted on the job in the United States. But new research has found that the use of information technology by law enforcement agencies can significantly cut the number of police killed or injured in the line of duty, reducing violence as much as 50 percent.

  • Unlawful Metadata Access Is Easy When We’re Flogging a Dead Law

    After watching this year’s media raids and the prosecution of lawyers and whistleblowers, it’s not hard to see why Australians wonder about excessive police power and dwindling journalistic freedom.

Each year, police alone access metadata in excess of 300,000 times.

  • Intelligent Camera Detects Roadside Bombs Automatically

    Roadside bombs are sneaky and effective killers. They are easy to manufacture and hide, making it the weapon of choice for insurgents and terrorists across the world. Finding and disabling these lethal devices is difficult. Dutch engineers have developed a real-time early-warning system. When mounted on a military vehicle, it can automatically detect the presence of those bombs by registering suspicious changes in the environment.

  • Why White Island Erupted and Why There Was No Warning

    White Island is one of several volcanoes in New Zealand that can produce sudden explosive eruptions at any time. In this case, magma is shallow, and the heat and gases affect surface and ground water to form vigorous hydrothermal systems. In these, water is trapped in pores of rocks in a super-heated state. Any external process, such as an earthquake, gas input from below, or even a change in the lake water level can tip this delicate balance and release the pressure on the hot and trapped water. The resulting steam-driven eruption, also called a hydrothermal or phreatic eruption, can happen suddenly and with little to no warning.

  • Global Arms Sales Up 4.6 Percent Worldwide; U.S. Companies Dominate

    Sales of arms and military services by the sector’s largest 100 companies (excluding those in China) totalled $420 billion in 2018, marking an increase of 4.6 percent compared with the previous year. The new data from SIPRI’s Arms Industry Database shows that sales of arms and military services by companies listed in the Top 100 arms-manufacturing companies have increased by 47 percent since 2002. The database excludes Chinese companies due to the lack of data to make a reliable estimate.

  • Paper-Based Sensor Detects Potent Nerve Toxins

    Chemist developed a new, paper-based sensor that can detect two potent nerve toxins that have reportedly been used in chemical warfare. The toxin, paraoxon, is thought to have been used in chemical warfare during the 1970s in what is now Zimbabwe, and later by the apartheid regime in South Africa as part of its chemical weapons program.

  • The New Kind of Warfare Reshaping Global Politics

    The list is long: Russian internet trolls interfering in the 2016 U.S. election; Russian operatives murdering Putin’s opponents abroad; Chinese spies manipulating Australian politics while the country’s coast guard ships harass Japanese fishing fleets, and much more. Simon Clark writes that these are not random acts of autocratic aggression. Rather, they are examples of a new form of warfare which is becoming a bigger challenge for the United States and its western allies: gray-zone conflict.

  • Advocates Push California City to Adopt Program That Pays People Who Don’t Shoot

    Fresno, California, has a homicide rate roughly twice the state average. In an effort to stem the violence, many advocates and Fresno residents have pushed city leaders to adopt an innovative violence interruption model called Advance Peace. J.

  • London Bridge Attack Follows “Dumbing Down” of Freed Terrorist Scheme – Expert

    The architect of the U.K. government program for moving convicted terrorists from prison into the community says the current system lacks the “legitimacy and credibility” required to rehabilitate extremists safely.

Henry Fradella and Michael White write His apology was confusing because that phrase “stop and frisk” is used to describe two different things.
