• An X-factor in coastal flooding: Natural climate patterns create hot spots of rapid sea level rise

    Many scientists have found evidence that climate change is amplifying the impacts of hurricanes. For example, several studies just published this month conclude that human-induced climate change made rainfall during Hurricane Harvey more intense. But climate change is not the only factor making hurricanes more damaging. A recent study showed that two converging natural climate processes created a “hot spot” from Cape Hatteras, North Carolina to Miami where sea levels rose six times faster than the global average between 2011 and 2015. We also showed that such hot spots have occurred at other points along the Eastern Seaboard over the past century. Now we see indications that one is developing in Texas and Louisiana, where it likely amplified flooding during Harvey – and could make future coastal storms more damaging. Accelerations in sea level rise are hard to predict, and it is unclear whether they will become more serious over time. But they make it even more urgent for coastal communities to take sea level rise seriously today.

  • Humidity may intensify heat stress to a point exceeding human endurance

    Climate scientists say that killer heat waves will become increasingly prevalent in many regions as climate warms. However, most projections leave out a major factor that could worsen things: humidity, which can greatly magnify the effects of heat alone. Now, a new global study projects that in coming decades the effects of high humidity in many areas will dramatically increase. At times, they may surpass humans’ ability to work or, in some cases, even survive.

  • U.S. ends 3-year ban on research involving enhanced-lethality viruses

    The U.S. National Institutes of Health (NIH) yesterday announced it was ending its three-year moratorium on funding of gain-of-function research, that is, research which aims to make extremely dangerous viruses even more dangerous in order to find a vaccine or cure for them. The U.S. government instituted the ban in 2014, against the backdrop of rising worries that these “gain-of-function” studies would allow scientists to increase the ability of the infectious disease to spread by enhancing its pathogenicity, or its ability to cause disease. Scientists who supported continuing research involving enhancing the transmissibility of infectious disease were not helped by a series of safety mishaps at federal research facilities.

  • New counter-terror rules give GPs bizarre incentives to refer mental health patients as radicalization threat

    Mental health trusts in England are now to play a vital role in processing the huge number of citizens referred under the government’s counter-terrorism strategy, known as Prevent. A new policy announced in November by the Home Office means urgent psychiatric care will now be provided by mental health trusts to those people with psychological problems who are referred to Prevent. But this will remove them from a pipeline of support under a program called Channel, aimed at those suspected of radicalizing. No one could possibly object to the provision of mental health care to those in need. But on deeper inspection, the integration of mental health trusts within the Prevent strategy reveals profound confusion within counter-terrorism policies. And the move could give health professionals perverse incentives to actually refer patients with mental health needs to Prevent – because they think it might get them help quicker.

  • “Cyberbiosecurity” and the protection of the life sciences

    Biology and biotechnology have entered a digital age, but security policies around such activities have not kept pace. New research outlines how the evolving nature of biotechnology should sound alarm bells for new ways to keep life sciences assets safe. This could be from accidental cyber-physical breaches, or more nefarious threats.

  • Biosecurity conference fosters international, multidisciplinary collaboration

    Biosecurity prevents unauthorized access, loss and intentional release of biological pathogens, information and equipment that may cause harm. Biosecurity professionals from across the United States and Mexico gathered on Arizona State University’s Tempe campus 7-8 December, the first time a biosecurity conference of this scope had taken place in Arizona and one of the largest ever to be held in the United States. Leaders in the field shared multidisciplinary approaches and perspectives on biosecurity.

  • Exposure to terror attacks may increase risk of migraine, other headaches

    Survivors of a terror attack have an increased risk of frequent migraine and tension headaches after the attack, according to a study. “We know a lot about the psychological effects of terror attacks and other extreme violence on survivors, but we don’t know much about the physical effects of these violent incidents,” said the study’s author. “Our study shows that a single highly stressful event may lead to ongoing suffering with frequent migraines and other headaches, which can be disabling when they keep people from their work or school activities.”

  • DNA has gone digital – what could possibly go wrong?

    Biology is becoming increasingly digitized. Researchers like us use computers to analyze DNA, operate lab equipment and store genetic information. But new capabilities also mean new risks – and biologists remain largely unaware of the potential vulnerabilities that come with digitizing biotechnology. In 2010, a nuclear plant in Iran experienced mysterious equipment failures which paralyzed Iran’s nuclear weapons program. Months later, a security firm was called in to troubleshoot an apparently unrelated problem, and found a malicious computer virus called Stuxnet, which was telling uranium-enrichment centrifuges to vibrate. Stuxnet demonstrated that cybersecurity breaches can cause physical damages. What if those damages had biological consequences? Could bioterrorists target government laboratories studying infectious diseases? What about pharmaceutical companies producing lifesaving drugs? As life scientists become more reliant on digital workflows, the chances are likely rising. The emerging field of cyberbiosecurity explores the whole new category of risks that come with the increased use of computers in the life sciences.

  • Bioelectronic “nose” detects food spoilage by sensing the smell of death

    Strong odors are an indicator that food has gone bad, but there could soon be a new way to sniff foul smells earlier on. Researchers have developed a bioelectronic “nose” that can specifically detect a key decay compound at low levels, enabling people to potentially take action before the stink spreads. It can detect rotting food, as well as be used to help find victims of natural disasters or crimes.

  • DHS establishes the Countering Weapons of Mass Destruction office

    Secretary of Homeland Security Kirstjen Nielsen last week announced the establishment of the Department of Homeland Security’s (DHS) Countering Weapons of Mass Destruction (CWMD) Office. DHS says that the CWMD Office will elevate and streamline DHS efforts to prevent terrorists and other national security threat actors from using harmful agents, such as chemical, biological, radiological, and nuclear material and devices to harm Americans and U.S. interests.

  • Analyzing recent research on causes of gun violence

    In 2015, over 36,000 people died from gunfire in the United States, according to the Centers for Disease Control and Prevention, with roughly two-thirds of those deaths being classified as suicide. America’s gun-murder rate is 25 times that of the other high-income nations, and the gun-suicide rate is eight times as high. Despite these numbers, the last extensive analysis of research into the origins of gun violence, conducted in 2004, was inconclusive. Consensus is growing in recent research evaluating the impact of right-to-carry concealed handgun laws, showing that they increase violent crime, despite what older research says.

  • U.S. medical profession unprepared for nuclear attack: Study

    Escalating tensions between Washington and Pyongyang over North Korea’s nuclear program have fueled concerns about the possibility of nuclear warfare, and a new study has found that American medical professionals are woefully unprepared to handle the needs of patients after a nuclear attack. “I was not surprised that the responses from the emergency medical community were relatively poor in terms of knowledge and attitudes, because that’s what you get with radiation-myths versus reality,” said the study’s lead author.

  • Explaining personal hurricane evacuation decisions

    Why do some people living in the path of a major hurricane decide to evacuate while others stay put? That’s what researchers want to know so that they can improve how emergency evacuations are handled. The researchers are gathering information about residents in areas hit by hurricanes Irma and Harvey to learn more about how people make decisions in risky situations. This will ultimately help officials and emergency personnel better manage evacuations in the future.

  • Lead poisoning risk at indoor firing ranges

    Indoor firing ranges may put hobby shooters, law enforcement officers and employees at risk from lead exposure, particularly if proper dust-control measures are not in place. We are seeing an increase in firing range–related lead poisoning in adults, which can result from faulty ventilation systems or just inadequate cleanup of lead dust,” says one expert. “Exposure can happen from inhaling the lead dust emitted when the firearm is discharged or from ingestion of lead from contaminated hands or food.”

  • Animal health as a marker for predicting epidemics in human populations

    Researchers know that zoonotic diseases — illnesses transmitted from animals to humans — are the culprit behind most of the outbreaks that circled the globe over the last decade. First monkeys, and then bats, were discovered to be carriers of the deadly strain of Ebola that killed thousands of people between 2014 and 2016. Mosquitos are behind the Zika and West Nile virus, while birds carry avian flu. Animal health is increasingly gaining focus as a marker for predicting health epidemics among the human population.
