• What it takes to be a forensic fingerprint examiner?

    Being a forensic examiner seems glamorous on TV. But working in a crime lab requires long hours of intense focus that are anything but action-packed. This is especially true for fingerprint examiners, who must focus on minute visual details that would leave most people cross-eyed. It’s not a job for everyone.Experts are developing tests to help identify people with the pattern-matching skills needed for analyzing fingerprints.

  • Using antimalarial compound to detect bloodstains

    As seen on crime shows, investigators use a combination of luminol and other substances to light up bloodstains at crime scenes. But now, researchers report that combining luminol with artemisinin, a natural peroxide and antimalarial treatment, reduces the risk of false positives compared to the traditional method.

  • No funds for California's earthquake early-warning system in Trump's proposed budget

    The Trump administration’s proposed budget would eliminate federal funding for an earthquake early warning system being developed for the U.S. West Coast. Critics say that if the relevant clauses in the budget proposal become law, the long-planned seismic warning effort will be killed. Scientists say the withdrawal of federal funds would likely end the early-warning project, which aims to send smartphone tremor alert messages to West Coast residents.

  • Israel to install earthquake early-warning system

    Israel has selected Ottawa, Canada-based Nanometrics to build an earthquake early-warning system in Israel. The alert system will give a 10-to-30-second alert of an impending earthquake. The system’s success depends on the distinction between two types of waves an earthquake generates — P waves (for primary) and S waves (for secondary). P waves are very fast, traveling through rock at between four and seven kilometers per second, and are thus the first waves to arrive at a recording station following an earthquake. An S-wave has a shearing motion that makes the rock vibrate perpendicular to its path. This movement slows the S-wave, so that it travels at two to five kilometers per second, or about half the speed of the P-wave. It is S waves which are almost entirely responsible for the damage and destruction associated with earthquakes.

  • The rising homegrown terror threat on the right

    Dealing effectively with far-right violence requires that we treat its manifestations as domestic terrorism. I consider domestic terrorism a more significant threat than the foreign-masterminded variety in part because it is more common in terms of the number of attacks on U.S. soil. The number of violent attacks on U.S. soil inspired by far-right ideology has spiked since the beginning of this century, rising from a yearly average of 70 attacks in the 1990s to a yearly average of more than 300 since 2001. I would argue that this trend reflects a deeper social change in American society. The iceberg model of political extremism, initially developed by Israeli political scientist Ehud Shprinzak, can illuminate these dynamics. Murders and other violent attacks perpetrated by U.S. far-right extremists compose the visible tip of an iceberg. The rest of this iceberg is under water and out of sight. It includes hundreds of attacks every year that damage property and intimidate communities. The significant growth in far-right violence in recent years is happening at the base of the iceberg. Changes in societal norms are usually reflected in behavioral changes. It is thus more than reasonable to suspect that extremist individuals engage in such activities because they sense that their views are enjoying growing social legitimacy and acceptance, which is emboldening them to act on their bigotry.

  • Drones help in better understanding of wildfires

    U.S. Geological Survey scientists and partners are taking technology to the next level, using unmanned aircraft systems (UAS) to acquire both fire intensity and emissions data during prescribed burns. This effort combines expertise from multiple USGS partners that could reduce the harmful effects of smoke impacts from use of prescribed burns. Lessening the risk to property and lives during wildfires is a primary purpose of prescribed burns.

  • Tech firms urge Congress to enact surveillance reforms

    More than thirty leading internet companies have sent a letter to the chair of the House Judiciary Committee asking for reforms to the law used for carrying out mass surveillance. The letter concerns Section 702 of the Foreign Intelligence Surveillance Act (FISA). The act must be renewed by Congress before the end of the year. Over the years, the U.S. security agencies have creatively interpreted the law to allow them to store information on potentially millions of U.S. citizens – even though the law specifically requires the opposite.

  • $2-million grant for training next generation of nuclear arms control experts

    Post-Cold War arsenal reductions by the United States and Russia have slowed, and both sides continue to keep many hundreds of weapons on hair trigger alert ready to launch within minutes of a country’s leader pushing the button. Meanwhile, concerns grow about nuclear programs in North Korea, South Asia, and the Middle East. Princeton University’s Program on Science and Global Security (SGS) has received a $2-million grant from the MacArthur Foundation. The award will support SGS’ efforts to educate and train the next generation of researchers and scientists studying nuclear non-proliferation, arms control and disarmament.

  • Creating high-speed internet lane for emergency situations

    In a disaster, a delay can mean the difference between life and death. Emergency responders don’t have time to wait in traffic — even on the congested information superhighway. Researchers are developing a faster and more reliable way to send and receive large amounts of data through the internet. By a creating a new network protocol, called Multi Node Label Routing protocol, researchers are essentially developing a new high-speed lane of online traffic, specifically for emergency information.

  • AI to aid in humanitarian efforts

    Mobile phones are one of the fastest growing technologies in the developing world with global penetration rates reaching 90 percent. However, the fact that most phones in developing countries are pre-paid means that the data lacks key information about the person carrying the phone, including gender and other demographic data, which could be useful in a crisis. Researchers have developed an AI algorithm to accurately predict the gender of pre-paid mobile phone users, so that emergency response teams would have better information about those affected by disasters.

  • Bomb squads to compete in annual Robot Rodeo

    Robots are life-saving tools for bomb squads and emergency response teams, providing them a buffer from danger. Sandia National Laboratories is hosting the 11th annual Western National Robot Rodeo, a four-day event where civilian and military bomb squad teams get practice using robots to defuse diverse, dangerous situations.

  • Service Academies Swarm Challenge: Expanding the capabilities UAV swarms

    More than forty Cadets and Midshipmen from the U.S. Military Academy, the U.S. Naval Academy, and the U.S. Air Force Academy helped expand the capabilities of swarms of highly autonomous unmanned aerial vehicles (UAVs) last month in the Service Academies Swarm Challenge. In the skies over Camp Roberts, an Army National Guard post north of Paso Robles, Calif., each academy demonstrated the innovative offensive and defensive tactics they had developed over the school year. The three-day experiment concluded with an exciting aerial battle in which the Naval Academy took home the win, a trophy, and bragging rights over its rival academies.

  • ICE-led anti-gang campaign nets 1,378 arrests nationwide

    A six-week nationwide gang operation led by U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) concluded this weekend with 1,378 arrests across the United States – the largest gang surge conducted by HSI to date. The operation targeted gang members and associates involved in transnational criminal activity, including drug trafficking, weapons smuggling, human smuggling and sex trafficking, murder and racketeering.

  • U.S., rejecting Turkish opposition, to arm Kurdish militia ahead of Raqqa battle

    The Trump administration has decided to arm Syria’s Kurdish fighters because it was “necessary” for recapturing the ISIS stronghold of Raqqa. The decision was made in the face of fierce opposition from Turkey, a NATO ally which regards the Syrian Kurds as terrorists. Turkey has been worried that a better-armed Kurdish militia — known as the Kurdish Peoples’ Protection Units (YPG) – would be in a stronger position to aid the PKK, a Turkish Kurdish group agitating for greater Kurdish autonomy in eastern Turkey. The YPG leads the Syrian Democratic Forces, or SDF, a multi-ethnic armed militia. Turkey was willing to agree to the arming of the non-Kurdish elements of the SDF, but the Pentagon concluded that without the YPG, the SDF would not be an effective fighting force.

  • The security problems now facing Emmanuel Macron, France’s new president

    Emmanuel Macron emerged from one of the most brutal and eventful election campaigns in recent European history as France’s next president. Macron has promised to increase security spending, strengthen internal security services and introduce new centers to integrate people returning from fighting for so-called Islamic State. But solving the riddle of France’s recent security woes is going to require wide-ranging action and reform. This will present the new president with one of the biggest challenges of his presidency. Macron will need to tackle the chronic, daily, security issues France faces and overcome the institutional atrophy and social marginalization which are such powerful drivers of insecurity. There is a reason, however, that previous administrations have not tackled these issues: they are politically explosive and economically costly. In a presidency that is already looking crowded with political challenges and policy promises, where building a broad base of support without a party after the parliamentary elections in June looks difficult at best, there is a risk that these issues will be once again pushed to the back of the queue.
