• Why is there so little research on guns in the U.S.? 5 questions answered

    Like other recent mass shootings, the events in Las Vegas were quickly followed by demands for change to gun control policy. But which policy do we choose? Following the Las Vegas shooting, debate has focused on bump stocks, accessories that allow a semiautomatic weapon to fire more rapidly. Will restrictions on them help prevent another mass shooting? Is there a better policy option? Unfortunately, the research we need to answer these questions doesn’t exist – and part of the problem is that the federal government largely doesn’t support it. Without increased funding for gun research, it will be extremely difficult for researchers to provide accurate answers to the gun policy questions currently under debate.

  • Mass killings happen randomly, but rate has remained steady

    Mass killings may have increasing news coverage, but the events themselves have happened at a steady rate for more than a decade, according to a new study. In the first ten months of 2016 — between 1 January 2016 and 4 October 2016 — there were 323 mass shooting incidents in the United States (mass shooting incidents are those in which four or more people are killed). Furthermore, some types of mass-killing events seem to occur randomly over time, making prediction difficult and response crucial.

  • Battling fires increases firefighters’ exposure to carcinogens

    The threat of getting burned by roaring flames is an obvious danger of firefighting, but other health risks are more subtle. For example, firefighters have been found to develop cancer at higher rates than the general population. Now researchers have measured how much firefighters’ exposure to carcinogens and other harmful compounds increases when fighting fires.

  • Homicide the largest contributor to years of lost life among African Americans

    Homicide is the largest contributor to potential years of life lost among black Americans, according to a new study. Homicide was the 12th highest contributor to potential years of life lost for white Americas. Black Americans are disproportionately affected by homicide, but the amount invested in homicide research is dramatically underrepresented in public health. Research on heart disease, white Americans’ No. 1 cause of potential years of life lost, received 341 grants and almost 600 publications during 2015; research on homicide received just a handful of federal grants and publications.

  • Noncompliance hobbles comprehensive background check policy for private-party gun sales: Study

    Of the three states that recently expanded comprehensive background check (CBC) policies to include all gun transfers, including those among private parties, only Delaware showed an overall increase in firearm background checks. Washington and Colorado had no changes, which the study authors say suggests that compliance and enforcement were incomplete. “The overwhelming majority of all firearms used for criminal purposes, some 80 percent, are acquired through private party transactions,” said one researcher. “By expanding background checks to include private-party transfers, there is a higher chance that these policies will make it harder for felons and other prohibited persons to acquire firearms and commit violent crimes.”

  • Finding confirms Assad’s systematic use of chemical weapons in Syria

    Samples from an attack in northern Syria on 30 March “prove the existence of sarin,” a deadly nerve agent, the director of the Organization for the Prohibition of Chemical Weapons (OPCW) said on 4 October. The attack injured dozens, but it did not kill anybody. So why is this finding important? Because it confirms a pattern of sarin use by the government of Bashar al-Assad.

  • More than half of police killings in U.S. not officially documented on death certificates

    Official death certificates in the United States failed to count more than half of the people killed by police in 2015 — and the problem of undercounting is especially pronounced in lower-income counties and for deaths that are due to Tasers, according to a new Harvard study. In contrast, a database from the London-based Guardian newspaper captured a large majority of these deaths, the study found.

  • A public health approach to stemming gun violence

    Public mass shootings in the United States have become more frequent. Unfortunately, it appears that these killings are somewhat contagious. They also seem to be becoming more deadly—largely because of the weaponry at the killers’ disposal. “A lesson from public health is that it is usually more effective to change the environment than to try to change people. The U.S. should use the same harm reduction approach to gun violence that it uses to treat other public health threats, like automobile crashes or air pollution—employing a wide variety of methods to reduce the problem,” says a public health expert.

  • “North Korea crisis could spark a global chain of nuclear strikes”: Luxembourg Forum

    Leading international experts on nuclear non-proliferation and world leaders met Monday in Paris for the International Luxembourg Forum on Preventing Nuclear Catastrophe to express their concern on the escalating crisis in nuclear weapons control. During his opening remarks, Tony Blair warned that “the proliferation of nuclear weapons is the most serious threat today to the fate of humankind.” Blair further said that “Proliferation begets further proliferation leading to risk of additional terrorist capability.”

  • Detecting nuclear materials used in dirty bombs

    Radiological material falling into the wrong hands is a constant security concern for governments around the world. Border agencies must scan incoming vehicles and freight for radioactive material, which is a challenging task, as huge volumes of both move across borders each day. Imperial College London’s physicists have developed two devices for detecting nuclear materials.

  • Training bystanders to act as first responders

    Blood loss is the leading cause of preventable death during an active shooter or intentional mass casualty event where a medical response is delayed. To educate the public – who often find themselves on the front line in emergency situations – a team led by a trauma surgeon from Rutgers New Jersey Medical School and EMS from University Hospital are directing the largest Stop the Bleed campaign in the state, teaching laypeople basic skills of hemorrhage control for immediate, on-the-scene care.

  • Terrorism and guns: Troubling implications for U.S.

    According to the authoritative Global Terrorism Database (GTD), firearms accounted for about 55 percent of fatalities in terrorist attacks even though guns were used in less than 10 percent of terrorist events. Attacks involving more common weapons such as explosives, incendiary weapons and vehicles, or melee weapons had fewer fatalities than attacks involving firearms.Among industrialized countries, the United States has the highest proportion of terrorist attacks in which the perpetrators used firearms.

  • FISA Section 702 reform bill a good Start, but improvements still needed: Critics

    Last Wednesday, the draft of the House Judiciary Committee’s bill to reauthorize and reform Section 702 of the Foreign Intelligence Surveillance Act (FISA) was made public. Section 702 permits the government to collect the content of communications of targets who are non-Americans located abroad, including communications they may have with Americans. Critics urge Congress to pass significant and meaningful reforms to Section 702 which address the serious constitutional concerns it raises, or allow that surveillance authority to expire.

  • Scientific basis of fingerprints too weak for legal certainty

    It may surprise many, especially those susceptible to the CSI effect, but fingerprint evidence is not conclusive beyond a reasonable doubt. A new American Association for the Advancement of Science (AAAS) working group report on the quality of latent fingerprint analysis says that courtroom testimony and reports stating or even implying that fingerprints collected from a crime scene belong to a single person are indefensible and lack scientific foundation.

  • Why a congressional ban on bump stocks is unlikely

    Even in the wake of the deadliest mass shooting in U.S. history, it appeared that nothing could shake the immovable stalemate over gun rights in Congress – but a strange thing happened: Republicans started talking about tightening regulations on firearms. But until Congress can prove otherwise, and Republicans in particular move from rhetoric to legislation, it’s reasonable to expect this latest bipartisan opening to meet a similar fate to the bipartisan move, in the wake of Sandy Hook, to expand background checks: That attempt, led by Senator Pat Toomey (R-Pennsylvania) and Senator Joe Manchin (D-West Virginia), could not overcome a Senate filibuster.
