• Flint water crisis: “Missing lead” in water pipes confirms cause of crisis

    A study of lead service lines in Flint’s damaged drinking water system reveals a Swiss cheese pattern in the pipes’ interior crust, with holes where the lead used to be. The findings support the generally accepted understanding that lead leached into the system because that water wasn’t treated to prevent corrosion. While previous studies had pointed to this mechanism, this is the first direct evidence. It contradicts a regulator’s claim earlier this year that corrosion control chemicals would not have prevented the water crisis.

  • A spate of acid attacks in London is part of an international problem

    A series of five acid attacks in one night in London has created a moment for the British government to take a more public stance on this growing problem. Available statistics suggest a sharp rise in attacks with corrosive substances in the United Kingdom. Data produced by the Metropolitan Police reveal that there were 455 crimes involving corrosive substances in London alone in 2016. Dozens of incidents have been reported so far this year. It is also clear that acid violence is a global problem. Acid Survivors Trust International reports a significant number of attacks in India, Colombia, Pakistan, Nepal, Bangladesh, Uganda, and Cambodia. There is thus a need to think about how to identify and support good practice internationally – in terms of prevention and supporting victims. This can help the efficient sharing of expertise and resources globally.

  • A case of atypical bovine spongiform encephalopathy (BSE) discovered in Alabama

    The U.S. Department of Agriculture (USDA) last week announced an atypical case of Bovine Spongiform Encephalopathy (BSE), a neurologic disease of cattle, in an eleven-year old cow in Alabama. This animal never entered slaughter channels and at no time presented a risk to the food supply, or to human health in the United States. BSE is not contagious and exists in two types — classical and atypical. Classical BSE is the form that occurred primarily in the United Kingdom, beginning in the late 1980s, and it has been linked to variant Creutzfeldt-Jakob disease (vCJD) in people.

  • Making gene editing safer

    Gene editing technologies have captured increasing attention from healthcare professionals, policymakers, and community leaders in recent years for their potential to cure disease, control mosquito populations, and much more. The potential national security applications and implications of these technologies are equally profound, including protection of troops against infectious disease, mitigation of threats posed by irresponsible or nefarious use of biological technologies, and enhanced development of new resources derived from synthetic biology, such as novel chemicals, materials, and coatings with useful, unique properties. DARPA is funding the efforts of seven teams aiming to develop new knowledge and tools to support responsible innovation in gene editing and protect against threats to genome integrity.

  • Current water use for food production is unsustainable

    About 40 percent of the water used for irrigation are unsustainable withdrawals that violate so-called environmental flows of rivers, a new study shows for the first time. If these volumes were to be re-allocated to the ecosystems, crop production would drop by at least 10 percent on half of all irrigated land, especially in Central and South Asia. Improvement of irrigation practices can sustainably compensate for such losses at global scale. More integrated strategies, including rainwater management could even achieve a 10 percent net gain of production.

  • Why has healthcare become such a target for cyber-attackers?

    More than 16m patient records were stolen from healthcare organizations in the United States and related parties in 2016. That year, healthcare was the fifth most targeted industry when it came to cyber-attacks. And earlier this year, Britain’s National Health Service was crippled by a ransomware attack that locked up the computers holding many of its records and booking systems. As connected technology becomes even more embedded in healthcare, this cyber-threat is only likely to grow. But if we want to protect our health from cyber-attacks, we shouldn’t fear technology. Instead, we need to understand it better and realize that the threat becomes much worse when people make simple mistakes.

  • New Web-based tools help protect the food supply

    Our economy, livelihood and wellbeing depend on food and its supply chains. Supply chains may break if a natural disaster destroys a crop in its primary production region, or if someone tampers with food to cause harm or raise profits. In such cases we need to find out quickly about these incidents and find alternative sources of food ingredients and supplies.

  • Climate change to deplete some U.S. water basins, reduce irrigated crop yields

    A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation. The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this region is projected to experience reduced precipitation by midcentury. Less rainfall to the area will mean reduced runoff into water basins that feed irrigated fields.

  • Human fingerprints on Europe’s recent heat

    This June, Europe experienced some remarkable heat. Temperature records were smashed across the west of the continent with extremely hot days followed by warm uncomfortable nights for many. Research has found that excess deaths during recent European heatwaves can be attributed to the human influence on the climate. These extreme heat events are becoming more common in Europe and around the world. Researchers say that in order to be prepared for future severe heatwaves, we need to understand how and why they are changing.

  • Bolstering counter-WMD capabilities in the southeast Europe and Black Sea regions

    The Defense Threat Reduction Agency’s (DTRA) DIABLO SHIELD training event and field exercise took place in Tblisi, Georgia, 24-28 April. DIABLO SHIELD emphasizes countering biological threats, and is part of the U.S. European Command’s (USEUCOM) Diablo Pathways series of engagements that support the development of counter-WMD capabilities in the southeast Europe and Black Sea regions.

  • Safe water for slum dwellers

    Attempts to deliver safe water to people living in some of the world’s poorest slums are falling at the final hurdle, according to experts. Sewage-contaminated drinking water causes serious illness such as diarrhea and other gastrointestinal and stomach problems – putting millions of lives at considerable risk each year. Globally, there are 1.7 billion cases of diarrhea annually resulting in over 0.5 million deaths of children under five years old. New research has shown that despite good progress, millions of slum dwellers are still exposed to considerable risk because water supplies are being contaminated by human waste just meters from the family home.

  • Decrease in lead exposure in early childhood likely responsible for drop in crime rate

    Exposure to lead in the preschool years significantly increases the chance that children will be suspended or incarcerated during their school careers, according to new research. Conversely, a drop in exposure leads to less antisocial behavior and thus may well be a significant factor behind the drop in crime over the past few decades.

  • Claim of greatly improved survival rate for gunshot victims debunked

    The survival rate of U.S. gunshot victims has not shown a marked improvement, as other recent studies have suggested, according to new research. The purported increase in survival rate had been credited to improvements in emergency treatment and medical care of critically injured patients. But on close analysis, researchers found problems in the way data was collected and coded.

  • New foot-and-mouth disease rapid diagnostic kit licensed

    DHS S&T announced today the licensing of a rapid-response (three-hour) Foot-and-Mouth Disease (FMD) diagnostic kit by the U.S. Department of Agriculture (USDA) Center for Veterinary Biologics (CVB). S&T says that the diagnostic kit, developed by a large research consortium of federal agencies, academia and animal health industry scientists, is the first licensed FMD diagnostic kit that can be manufactured on the U.S. mainland, critical for a rapid response in the event of a FMD outbreak.

  • How plague attacks us – and how we should defend ourselves

    The plague that is believed to have caused the Black Death still occasionally ravages populations, albeit to a much smaller extent than before. Now we know more about how the bacteria attack us. But how does the plague bacterium attack human beings, and how does the body defend against its constantly evolving attacks? New research on the bacterium is yielding new answers.
