• For a flooded Midwest, climate forecasts offer little comfort

    Floods are triggered by extreme rainfall events, often combined with ground conditions, such as saturated or frozen ground, that make it harder for water to percolate down into soil, which increases runoff. Global warming has the potential to intensify the Earth’s water cycle, which will alter the quantity, frequency, intensity and duration of rain and snowfall. As my research and work by others has shown, all of these changes raise the risk of floods for Midwest states.

  • A billion more people will be exposed to diseases as world temperatures rise

    As many as a billion people could be newly exposed to disease-carrying mosquitoes by the end of the century because of global warming, says a new study that examines temperature changes on a monthly basis across the world.

  • Killer robots already exist, and they’ve been here a very long time

    The question is not so much whether we should use autonomous weapon systems in battle – we already use them, and they take many forms. Rather, we should focus on how we use them, why we use them, and what form – if any – human intervention should take.

  • Israel’s Carbyne, RapidSOS partner to improve 911 calls

    Dialing 911 in an emergency is something that we’ve all been instructed to do since childhood. And old-fashioned, simple dialing is what most of us are still doing, even in an age of far more sophisticated technology. Next-gen public safety tech company will provide call takers with more informative real-time data to help first responders locate and treat callers.

  • Few pathways to an acceptable climate future without immediate action: Study

    A new comprehensive study of climate change has painted over 5 million pictures of humanity’s potential future, and few foretell an Earth that has not severely warmed. But with immediate action and some luck, there are pathways to a tolerable climate future, scientists say.

  • Chances of UN banning killer robots looking increasingly remote

    The Campaign to Stop Killer Robots warns chances of achieving a U.N. treaty banning the development, production and use of fully autonomous lethal weapons, also known as killer robots, are looking increasingly remote. Experts from some 80 countries are attending a weeklong meeting to discuss the prospect of negotiating an international treaty.

  • Detecting radioactive material remotely

    Physicists have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique is able to detect shielded material from a distance. The method improves upon current technologies that require close proximity to the radioactive material.

  • Historic, widespread flooding to continue through May

    Nearly two-thirds of the Lower 48 states face an elevated risk for flooding through May, with the potential for major or moderate flooding in 25 states, according to NOAA’s U.S. Spring Outlook issued today. The majority of the country is favored to experience above-average precipitation this spring, increasing the flood risk.

  • Rapidly melting tall ice-cliffs may trigger faster sea-level rise

    Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when the ocean melts the front of the ice, and ice cliff above falls down, a new study presents another method of calving: slumping. And this process could break off much larger chunks of ice at a quicker rate.

  • Dunford: Google’s work with China “challenges” U.S. military advantage

    The top U.S. military officer has called out U.S. technology giant Google for its artificial intelligence venture in China, saying it “creates a challenge” in maintaining a U.S. military advantage over the Chinese.

  • Biotechnology advances offer opportunities for actors with malicious intent

    Over the past decade, the biotechnology economy has experienced remarkable growth, resulting in the rapid expansion of biological knowledge and application. These advances create openings for actors with malicious intent to harness readily available tools and techniques to create biological threats or bioweapons.

  • Offshore wind energy potential not exploited by U.S. energy companies

    When it comes to wind energy, the United States is sitting on a gold mine, so to speak. It’s a moment of untapped potential that, if harnessed properly, could transform the way the U.S. uses energy, one expert says.

  • Satellite technology detects, and may prevent, genocide

    Many of the world’s worst human rights abuses, including genocides, occur in areas that are difficult to observe. “Smallsat” — short for small satellite — technology can detect human rights abuses and violations. The information collected by this technology provides evidence that can be used to corroborate refugee accounts of atrocities in international courts.

  • Cyber toolkit for criminal investigations

    cybercrimes reached a six-year high in 2017, when more than 300,000 people in the United States fell victim to such crimes. Losses topped $1.2 billion. Cybercriminals can run, but they cannot hide from their digital fingerprints.

  • Do we need a moratorium on germline gene editing?

    In the wake of the news from China about He Jiankui’s gene-edited babies, many scientists are calling for a moratorium on germline gene-editing. Nature considered the topic sufficiently important to publish the call by several top researchers and ethicists for a moratorium.
