• Seismic early warning could save lives in Nepal’s next Big One

    Just before noon on 25 April 2015, a magnitude 7.8 earthquake that maxed out the seismic intensity scale shook the entire nation of Nepal. Originating about 100 km northwest of the capital city of Kathmandu, this earthquake along with a magnitude 7.1 aftershock on 12 May killed nearly 9,000 people and injured nearly 22,000 more while damaging or destroying more than 600,000 structures. Scientists say that if sensors had been near the epicenter of the 2015 earthquake, they could have detected it up to 80 seconds before it reached Kathmandu. Even factoring in the time it would take to corroborate the signal with other sensors and transmit a warning to everyone’s cell phones—which are just as abundant in Nepal as they are in America—people could have gotten more than a minute warning.

  • Israeli air strike destroys Iranian missile storage facilities in Syria

    An overnight Israeli air strike destroyed more than 200 Iranian mid-range missiles which Iran stored at Syrian military bases near Hama. These missiles were more accurate, and were capable of carrying a bigger warhead, than other missiles available to Hezbollah and the Syrian military. The attack killed 26 military personnel, including 18 Iranian officers. Bashar-al-Assad’s victory in the civil war in Syria has opened the door for Iran, his main ally, to try and turn Syria into an Iranian forward military base against Israel.

  • Stolen guns not an important source of guns used in crimes

    Only about 1 percent of all gun transactions in the United States are thefts, and there is no evidence that theft is an important source of guns to those who use them to commit violent crimes. This and other evidence challenge the popular belief that crimes are mostly committed using stolen weapons.

  • Radiation detection device to help in detecting nuclear weapons, materials

    Researchers have developed a next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use. Specifically, the high-performance material is used in a device that can detect gamma rays, weak signals given off by nuclear materials, and can easily identify individual radioactive isotopes. Potential uses for the new device include more widespread detectors — including handheld — for nuclear weapons and materials as well as applications in biomedical imaging, astronomy and spectroscopy.

  • The dark possible motive of the Toronto van attacker

    Like other Canadians, I was horrified upon learning of a van attack along Toronto’s famed Yonge Street this week. Struggling to make sense of it, my first question was: “Why?” As it turns out, the attack was possibly a disturbing reprise of a similar massacre, targeting mostly women and perceptively “sexually active” men in the California community of Isla Vista in May 2014.

  • Exploring Arctic clues to secure future

    The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in the future, Sandia scientists say.

  • World’s biggest DDoS-for-hire service taken down

    The administrators of the DDoS marketplace webstresser.org were arrested on 24 April 2018 as a result of Operation Power Off, a complex investigation led by the Dutch Police and the UK’s National Crime Agency with the support of Europol and a dozen law enforcement agencies from around the world. The webstresser.org was considered the world’s biggest marketplace to hire Distributed Denial of Service (DDoS) services, with over 136 000 registered users and 4 million attacks measured by April 2018.

  • Future of testing and treating chlorine gas attacks

    As experts sort through questions around recent chemical attacks in Syria, future answers to quickly testing and treating those who may have been exposed to chlorine gas may lie in chlorinated lipids, says a scientist.

  • Exposure to domestic violence costs U.S. government $55 billion each year

    The federal government spends an estimated $55 billion annually on dealing with the effects of childhood exposure to domestic violence, according to new research. The results of a study on the national economic impact of exposure to domestic violence showed higher health-care costs, higher crime rates and lower productivity in children as they aged.

  • Next California's Big One could kill hundreds, cause $100 billion in losses, trap 20,000 in elevators

    What will happen when the next big earthquake hits northern California? Researchers say that if a tremor similar in magnitude to the 1906 San Francisco earthquake were to hit today, it could kill 800 people, cause more than $100 billion in economic losses from the shaking and subsequent fires, and trap roughly 20,000 people in elevators across northern California.

  • Hamas drone maker killed in Malaysia

    A Palestinian engineer whom Hamas claimed worked for them, was shot and killed by unknown assailants in Malaysia where he taught. Hamas, the terrorist organization that exercises complete political and military control over the Gaza Strip blamed Israel for killing Fadi al-Batsh, who was described by the terrorist group’s leader, Ismail Haniyeh, as a member of Hamas with “an honorable reputation in science.”

  • For nuclear weapons reduction, a way to verify without revealing

    In past negotiations aimed at reducing the arsenals of the world’s nuclear superpowers, chiefly the U.S. and Russia, a major sticking point has been the verification process: How do you prove that real bombs and nuclear devices — not just replicas — have been destroyed, without revealing closely held secrets about the design of those weapons? New isotope-detection method could prove compliance but avoid divulging secrets.

  • Making combat vehicles lighter

    The military spends several billion dollars each year on fuel consumption, which could be reduced by lessening the weight of ships, aircraft, ground vehicles, and cargo. Researchers have developed and successfully tested a novel process — called Friction Stir Dovetailing — that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient.

  • Trust worthiness of forensic handwriting in court questioned

    Forensic handwriting specialists are often called on to testify in court about the origins of a few lines of writing, or to determine whether a specific person has written a sentence. A new study indicates that experts are not 100 percent adept at assessing how often specific handwriting features occur in the general population.

  • The HayWired scenario: a major earthquake in the San Francisco Bay area

    Last week the USGS, along with approximately sixty partners, released a new fact sheet that summarizes a report from a larger study of what could happen during a major earthquake in the San Francisco Bay area along the Hayward Fault – arguably one of the most urbanized and interconnected areas in the nation. Earthquakes pose a threat to the safety of more than 143 million people living in the United States, and estimated long-term annualized earthquake losses in the United States are more than $6.1 billion per year.
