• Building a biosafety and biosecurity toolkit for a safer gene editing research

    A new DARPA program could help unlock the potential of advanced gene editing technologies by developing a set of tools to address potential risks of this rapidly advancing field. The Safe Genes program envisions addressing key safety gaps by using those tools to restrict or reverse the propagation of engineered genetic constructs. Safe Genes was inspired in part by recent advances in the field of “gene drives,” which can alter the genetic character of a population of organisms by ensuring that certain edited genetic traits are passed down to almost every individual in subsequent generations.

  • Climate change increased chances of record rains in Louisiana by at least 40 percent

    Human-caused climate warming increased the chances of the torrential rains that unleashed devastating floods in south Louisiana in mid-August by at least 40 percent, according to a team of NOAA and partner scientists. “We found human-caused, heat-trapping greenhouse gases can play a measurable role in events such as the August rains that resulted in such devastating floods, affecting so many people,” says the lead author of a new study.

  • Climate change likely to increase frequency, magnitude of severe U.K. flooding events

    Last December, following severe flooding across parts of Northern England and Scotland and on the eve of the climate summit in Paris – which was held 30 November – 12 December 2015 — Lord Deben, chairman of the U.. Committee on Climate Change, said: “Defenses that might historically have provided protection against a 1 in 100 year flood will, with climate change, provide a much lower level of protection and be overtopped more frequently. The latest projections suggest periods of intense rainfall could increase in frequency by a factor of five this century as global temperatures rise.”

  • U.S. experiences 5th warmest summer on record

    An oppressively hot Summer 2016 for many across the contiguous United States tied 2006 as the 5th warmest in 122 years of record keeping. The average summer U.S. temperature was 73.5 degrees F, 2.1 degrees above average, according to scientists from NOAA. . Every state in the continental United States and Alaska were warmer than average this summer – with lower 48 also having 3rd warmest year to date and second wettest August. Precipitation totaled 0.60 inch above average, making summer the 24th wettest on record.

  • Growing concern about amateur “biohackers” creating biological weapons

    American and European security agencies have been increasingly focusing on the risk that “biohackers” – scientists who use genome-editing techniques to change life forms by increasing or decreasing the function of genes — could develop biological weapons or other dangerous biological substances. The problem is not only – or even mostly – with the work of professional scientists. Rather, the real danger lies with amateur scientists around the world who have started to use gene-editing techniques after the tools became cheap and readily available.

  • Keeping pace with the fast-developing science of gene drives

    The emerging science of gene drives is drawing attention for its potential to help with critical health issues such as mosquito-borne diseases and environmental concerns such as agricultural pests and invasive species. At its most basic, a gene drive operates outside the traditional realm of genetics, in which an offspring has a 50-50 chance of inheriting a trait from one of its parents. A gene drive introduces a trait that will spread — or drive — through a population. “The science of gene drives is moving very fast,” says an expert. “[O]ur ability to assess the risks of gene drives, to oversee them with regulatory agencies, and to have a public discussion around gene drives is falling behind the science — We don’t want to wait until we have the technology in front of us to have discussions about regulation, oversight, ethics, and engagement.”

  • Human activity has been causing climate change for nearly two centuries

    An international research project has found human activity has been causing global warming for almost two centuries, proving human-induced climate change is not just a twentieth century phenomenon. The study found warming began during the early stages of the Industrial Revolution and is first detectable in the Arctic and tropical oceans around the 1830s, much earlier than scientists had expected.

  • Solar-powered Ring Garden combines desalination, agriculture for drought-stricken California

    With roughly 80 percent of California’s already-scarce water supply going to agriculture, it is crucial for the state to embrace new technologies that shrink the amount of water required to grow food. Alexandru Predonu has designed an elegant solution which uses solar energy to power a rotating desalination plant and farm that not only produces clean drinking water for the city of Santa Monica, but also food crops — including algae.

  • Data shows growing political polarization on climate change

    New research discusses the increasing partisan polarization of American attitudes toward climate change. The article details the escalation of partisan polarization, particularly toward environmental protection and climate change, over the past few decades in America, showing an increasing gap between self-identified Republicans’ and Democrats’ attitudes toward human-caused climate change. While Democrats have increasingly accepted the reality and seriousness of climate change over the past two decades, Republicans have become more skeptical.

  • GW Program on Extremism expands research, expertise

    Since its launch in June 2015, the George Washington University’s Program on Extremism has contributed research and analysis on violent and non-violent extremism. GW notes the program’s report ISIS in America: From Retweets to Raqqa has been used by policymakers and law enforcement as a trusted source. Now in its second year, program leadership says they will continue to grow as a leading resource of expertise and research on extremism by expanding with new initiatives and hires.

  • Chicago becomes first city to launch Array of Things, an innovative urban sensing project

    This week in Chicago, the Array of Things team begins the first phase of the groundbreaking urban sensing project, installing the first of an eventual 500 nodes on city streets. By measuring data on air quality, climate, traffic, and other urban features, these pilot nodes kick off an innovative partnership among different organizations aiming better to understand, serve, and improve cities.

  • Assessing climate change vulnerability in urban America

    Impacts of climate change – rising sea levels, heat waves, rising rates of diseases caused by ticks, fleas, and mosquitoes, and many more — will affect cities across the country. One of the first efforts systematically to assess how cities are preparing for climate change shows that city planners have yet fully to assess their vulnerability to climate change, leaving serious risks unaddressed. Most city planners have yet to prepare for climate-related risks and the consequences.

  • Pace of Earth’s warming “unprecedented in 1,000 years”: NASA

    The warming of the planet is proceeding at a pace not experienced within the past 1,000 years, making it “very unlikely” to keep warming to 1.5 degrees Celsius – the goal agreed by nations at the Paris climate summit last December. Recent research found that continuing current levels of carbon dioxide emissions for just five more years will eliminate any chance of restraining temperatures to a 1.5C increase and avoid runaway climate change.

  • Large-scale metamaterials could earthquake-proof buildings in tremor-prone regions

    Metamaterials – artificial structures that exhibit extraordinary vibrational properties – could come to the rescue of regions threatened by earthquakes, according to new research. The study, performed by researchers in Europe and involving detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks.

  • Nuclear forensics summer program trains students for a future in nuclear security

    A sure sign of summer is the return of interns to the Lawrence Livermore campus. Students interact with premier researchers and access equipment and facilities not available anywhere else, while scientists lay groundwork for advancing their fields. LLNL runs an eight-week summer internship for students interested in nuclear science and its range of specialties — nuclear forensics, environmental radiochemistry, nuclear physics, and beyond. Together, these disciplines support the laboratory’s nuclear security mission through analysis of nuclear processes and properties.
