• Scrapping sea level protection puts Australian homes at risk

    As the science on the coastal impacts of climate change gets stronger, the protections for Australia’s coastal communities are getting weaker. Along the eastern seaboard of Australia, where most Australians live, state governments are relaxing their policies and largely leaving it to local councils to decide if homes can be built in low-lying areas.Over the past fifty years, there have been twenty-five national inquiries and reports into coastal management. Those inquiries have overwhelmingly come to the conclusion that rather than leaving it to local councils, Australia needs one set of clear, national guidelines on coastal development and infrastructure. That is the opposite of what we are now seeing around Australia, with a mish-mash of different rules in different states. If that continues, everyone will pay.

  • Food security and self-provision of major cities

    Wealthy capital cities vary greatly in their dependence on the global food market. The Australian capital Canberra produces the majority of its most common food in its regional hinterland, while Tokyo primarily ensures its food security through import. The Copenhagen hinterland produces less than half of the consumption of the most common foods. For the first time, researchers have mapped the food systems of capital cities, an essential insight for future food security if population growth, climate change, and political instability will affect the open market.

  • Global map predicts giant earthquakes

    Researchers have developed a new global map of subduction zones, illustrating which ones are predicted to be capable of generating giant earthquakes and which ones are not. The research comes nine years after the giant earthquake and tsunami in Sumatra in December 2004, which devastated the region and many other areas surrounding the Indian Ocean, and killed more than 200,000 people.

  • Cybersecurity isn’t all about doom and gloom

    Much is made in the press of the devastating effects that weak cybersecurity is having on the economy in the United Kingdom and globally. The threat is compounded by a significant skills shortage. The U.K. government thinks the problem is so severe that it has identified cybersecurity as a Tier 1 national security threat and invested 860 million pounds to defend the country’s digital shores. What all this means is that there is money to be made from cybersecurity and small businesses should not fear it but embrace it. The business opportunities are boundless in cybersecurity. One area that is promising in this sense is the move towards smart cities. As the infrastructure around us, such as traffic lights and utilities becomes more regularly controlled via computers, market opportunities emerge

  • Zapping bridges with electricity to test for corrosion

    One out of nine of the nation’s bridges is structurally deficient and that more than 30 percent of bridges have exceeded their 50-year design life; the average age of the nation’s bridges is currently forty-two years. Motorists in the United States make more than 200 million trips across bridges rated structurally deficient or in need of significant maintenance and yearly inspection. Of the more than 17,000 bridges in New York, 12.5 percent are structurally deficient and 27 percent are considered functionally obsolete. One major culprit for bridges’ deterioration: corrosion of reinforcing steel. New testing method could replace expensive, time-consuming visual inspections.

  • New Jersey shore to face unprecedented flooding by mid-century

    Geoscientists estimate that the New Jersey shore will likely experience a sea-level rise of about 1.5 feet by 2050 and of about 3.5 feet by 2100 — 11 to 15 inches higher than the average for sea-level rise globally over the century. That would mean, the scientists say, that by the middle of the century, the one-in-ten year flood level at Atlantic City would exceed any flood known there from the observational record, including Superstorm Sandy.

  • No need to worry about getting fried by gamma ray burst

    If recent news that University of Alabama in Huntsville (UAH) researchers observed the largest gamma ray burst ever has you nervous about getting blasted into extinction by a massive burst from space, the UAH researchers have good news. The chances of Earth being fried by a burst are exceedingly rare.

  • New Silicon Valley focus on cybersecurity

    The last time Silicon Valley focused on cybersecurity was in the 1990s. That focus saw the emergence of two giants: McAfee and Symantec. The two companies remain the most recognizable household names, thanks to their traditional firewall and anti-virus products. Now they find the arena which they thought was their own encroached from two sides. On one side there are tech giants like Hewlett-Packard and Cisco Systems, which see new revenue opportunity in cybersecurity. On the other side there is a rush of start-ups backed by large investments of venture capital.

  • Protecting cars from hackers

    A U.S. senator has asked twenty automobile manufacturers how each plans to stave off wireless hacking attempts on the computer systems of the vehicle they manufacture, and also how they protect driver privacy. The questions by Senator Ed Markey (D-Massachusetts) indicate that he will demand that carmakers apply computer-industry security processes, including implementation of anti-virus software, incident logging, incident-response planning, software vulnerability patching, and third-party penetration testing — the last of which would stage real hacker attacks on mass-production vehicles.

  • Lawmakers: Old plastic gun law has not kept pace with technology

    The U.S. House of Representativesvoted last Tuesday to renew the 25-year old Undetectable Firearms Actwhich prohibits firearms that can evade metal detectors and X-ray machines. Law enforcement agencies say that developments in 3D printing make the law insufficient, and lawmakers who proposed amending the Act say that the only way to make such guns detectable is to require that at least one component of the firing mechanism in a plastic gun contain enough metal to be detectable in a magnetometer — and that that component be undetachable. The NRA opposes these requirements, saying that they would infringe on the Second Amendment rights of citizens.

  • Cyber Gym in Israel trains cyber-defenders

    A group of IT and infrastructure companies in Israel have teamed up to launch Cyber Gym.The facility, inaugurated this month by Israel Electric Corp. (IEC), will train participants to defend against cyber attacks.When Sivan Shalom,  Israel’s Infrastructure and Energy Minister, was asked whether Israel was more concerned about a physical or a virtual attack, he said: “I think the future battle will be in cyberspace.”

  • One percent of Swedish criminals commit 63 percent of all violent crimes

    The majority of all violent crime in Sweden is committed by a small number of people. Researchers have examined the case of all the people who were brought up on charges of violent crimes in Sweden between 1973 and 2004 – 2.5 million people in all. Of the 2.5 million individuals included in the study, 4 percent were convicted of at least one violent crime — 93,642 individuals in total. Of these convicted at least once, 26 percent were re-convicted three or more times, thus resulting in 1 percent of the population (23,342 individuals) accounting for 63 percent of all violent crime convictions during the study period.

  • Prolonged viewing of terrorist incident media coverage tied to acute stress

    Stepping away from the television, computer screen or smartphone in the aftermath of terrorist attacks or mass shootings may be beneficial to your mental health. This is the takeaway from a new study showing that six or more daily hours of exposure to media coverage of the Boston Marathon bombings in the week afterward was linked to more acute stress than having been at or near the marathon. Acute stress symptoms increased with each additional hour of bombing-related media exposure via television, social media, videos, print, or radio.

  • Virginia Tech to get $2.6 million to test unmanned aircraft systems

    The Commonwealth of Virginia announced it will award more than $2.6 million over three years in Federal Action Contingency Trust (FACT) funds to Virginia Tech to operate an unmanned aircraft systems test site in the state, officials from the governor’s office said. The test range is operated by the Mid-Atlantic Aviation Partnership, which is led by Virginia Tech and Rutgers University and represents an effort safely to develop unmanned aircraft systems. The University of Maryland has also agreed to partner with Virginia Tech and Rutgers on unmanned aircraft system integration.

  • Sea-level rise to drive flooding regardless of changes in hurricane activity

    Clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property — sea-level rise — according to a team of researchers. Since 1970, more than 60 percent of all economic losses — about $400 billion — occurred in the North Atlantic, even though it is one of the least active basins for hurricanes.The scientists say accelerated sea-level rise certainly will increase the flooding and property damage triggered by tropical cyclones — commonly known as hurricanes in the Atlantic and Northern Pacific — but predicting where, how often, and how powerful these storms will be when they make landfall is full of uncertainty.
