• “Liquid Forensics” Checks Safety of Drinking Water

    Ping! The popular 1990 film, The Hunt for Red October, helped introduce sonar technology on submarines to pop culture. Now, nearly thirty years later, a team of scientists is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume.

  • Huawei CVs Show Close Links with Military, Study Says

    A study of the employment information of thousands of Huawei staff has revealed deeper links with the Chinese military and intelligence apparatus than those previously acknowledged by China’s biggest telecom equipment maker. The findings are likely to add fuel to the debate among governments around the world over whether to block Huawei’s gear from the rollout of 5G telecoms networks for security reasons. Kathrin Hille writes in the Financial Times that The findings are likely to add fuel to the debate among governments around the world over whether to block Huawei’s gear from the rollout of 5G telecoms networks for security reasons. “Huawei has gone to great lengths saying they have no links with the Chinese military and security institutions,” said Prof. Balding. “The narrative they spin is false — military connections quite clearly run deep.” Analysts said the systemically close ties documented in the study reflected a pattern far beyond Huawei. One expert said such sharing or co-ordination of personnel across defense and commercial research activities was consistent with China’s national strategy for military-civil fusion.

  • U.S. Wants to Isolate Power Grids with “Rretro” Technology to Limit Cyber-attacks

    The U.S. is very close to improving power grid security by mandating the use of “retro” (analog, manual) technologies on U.S. power grids as a defensive measure against foreign cyber-attacks that could bring down power distribution as a result. Catalin Cimpanu writes in ZDNet that the idea is to use “retro” technology to isolate the grid’s most important control systems, to limit the reach of a catastrophic outage.

  • Making the World Earthquake Safe

    Can fake earthquakes help safeguard nuclear reactors against natural disasters? Visitors to this year’s Royal Society Summer Science Exhibition will be given the opportunity to find out for themselves thanks to new research.

  • Largest-ever simulation of the Deepwater Horizon spill

    In a 600-ft.-long saltwater wave tank on the coast of New Jersey, a team of NJIT researchers is conducting the largest-ever simulation of the Deepwater Horizon spill to determine more precisely where hundreds of thousands of gallons of oil dispersed following the drilling rig’s explosion in the Gulf of Mexico in 2010.

  • Rectifying a wrong nuclear fuel decision

    In the old days, new members of Congress knew they had much to learn. They would defer to veteran lawmakers before sponsoring legislation. But in the Twitter era, the newly elected are instant experts. That is how Washington on 12 June witnessed the remarkable phenomenon of freshman Rep. Elaine Luria (D-Norfolk), successfully spearheading an amendment that may help Islamist radicals get nuclear weapons. The issue is whether the U.S. Navy should explore modifying the reactor fuel in its nuclear-powered vessels — as France already has done — to reduce the risk of nuclear material falling into the hands of terrorists such as al-Qaida or rogue states such as Iran. Luria says no. Alan J. Kuperman writes in the Pilot Online that more seasoned legislators have started to rectify the situation by passing a spending bill on 19 June that includes the funding for naval fuel research. They will have the chance to fully reverse Luria in July on the House floor by restoring the authorization. Doing so would not only promote U.S. national security but teach an important lesson that enthusiasm is no substitute for experience.

  • Desalination is booming as cities run out of water

    It’s been a long time coming for desalination—desal for short. For decades, we have been told it would one day turn oceans of salt water into fresh and quench the world’s thirst. But progress has been slow. Jim Robbins writes in Wired that that is now changing, as desalination is coming into play in many places around the world. Several factors are converging to bring new plants on line. Population has boomed in many water-stressed places, including parts of China, India, South Africa, and the United States, especially in Arizona and California. In addition, drought—some of it driven by a changing climate—is occurring in many regions that not that long ago thought their supplies were ample.

  • How climate change impacts the economy

    Warmer temperatures, sea level rise and extreme weather will be deleterious to the U.S. economy: Rising temperatures damage property and critical infrastructure, impact human health and productivity, and negatively affect sectors such as agriculture, forestry, fisheries, and tourism. The demand for energy will increase as power generation becomes less reliable, and water supplies will be stressed. Damage to other countries around the globe will also affect U.S. business through disruption in trade and supply chains.

  • Germany warns Huawei to meet Germany’s security requirements

    Germany warned Huawei that the company must meet Germany’s security requirements before the company will be allowed to bid on building the 5G infrastructure in Germany. Germany has so far resisted U.S. pressure to exclude Huawei from the project. The United States has long suspected Huawei of serving the interests of Chinese intelligence, and Washington has argued that Huawei technology could be used for spying purposes by China.

  • NIST updates to help defend sensitive information from cyberattack

    An update to one of the National Institute of Standards and Technology’s (NIST) information security documents offers strategies to help protect sensitive information that is stored in computers supporting critical government programs and high value assets. The new companion publication offers enhanced security for information stored in critical programs and assets.

  • Optimizing use of future wave electricity generators during disaster

    When hurricanes strike, loss of electricity ranks as one of the top concerns for relief workers. Blackouts lasting a week or more can hamper recovery efforts, shutter hospitals, threaten public health and disrupt transportation. The months-long effort to restore power to Puerto Rico following the 2017 hurricane season has led to renewed interest in finding innovative ways to get affected power grids back online. Researchers look to develop a strategy for how floating devices that harness the energy of the oceans’ waves might be able to provide this much needed aid.

  • Melting of Himalayan glaciers has doubled in recent years

    Almost one billion people depend on melt-water from Himalayan glaciers for the water they need, but global warming has dramatically increased the pace of glacier melting. A new analysis, spanning forty years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000 — double the amount of melting that took place from 1975 to 2000.

  • Vulnerable grid: Argentina's nationwide blackout

    Blackouts which affect an entire country are incredibly rare – but one just hit Argentina on Sunday. Since April, an electricity transmission connection between two power plants in Colonia Elia and Nueva Campana has been out of service. Even with that connection not in service, Argentina’s electrical grid was supposed to withstand another connection being severed from the grid. But when a second connection went offline on Sunday, the entire national grid was put out of action.

  • With floods and droughts increasing, communities take a new look at storing water underground

    Groundwater recharging – that is, actively moving water underground, a practice known as managed aquifer recharge (MAR) — is the latest wave in water security. There are about 1,200 managed aquifer recharge projects in 62 countries. MAR can be used to restore depleted aquifers, rehabilitate ecosystems and cleanse polluted water. But there are challenges as well.

  • It’s Alive! Creating innovative “living” bridge

    Engineers have designed a unique living laboratory on a heavily traveled iconic bridge which could change the way infrastructure is viewed. The Memorial Bridge, which links Portsmouth, New Hampshire to Kittery, Maine, has been outfitted with data sensors that have transformed it into a self-diagnosing, self-reporting “smart” bridge that captures a range of information from the health of the span to the environment around it.
