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.

Dream of ideal “invisibility” cloaks for stress waves dashed
Whether Harry Potter’s invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study says. It would have perfectly steered stress waves in the ground, like those emanating from a blast, around objects like buildings to make them “untouchable.”

Finding and fixing natural gas leaks quickly, economically
From production to consumption, natural gas leaks claim lives, damage the climate and waste money. Researchers are working on better ways to find and fix gas leaks quickly and inexpensively from one end of the system to the other.

Nuclear energy regulators need to bring on more cyber experts, watchdog says
The Nuclear Regulatory Commission is facing a mass exodus of cybersecurity experts in the years ahead, which could limit its ability to ensure the nation’s nuclear power plants are safe from digital attacks, an internal watchdog found. Jack Corrigan writes in Defense One that Nearly one-third of NRC’s cybersecurity inspectors will be eligible for retirement by the end of fiscal 2020, and agency officials worry they aren’t training enough people to take their place, according to the NRC Inspector General. With nuclear power stations becoming increasingly popular targets for online adversaries, the shortage of cyber expertise could leave the agency struggling to do its job, auditors said.

Sensors may not make infrastructure safer
Simply driving down the road gives you a sense for the current state of our infrastructure: crumbling and in need of repair. New technology like sensors offers a way for inspectors to peer inside the systems almost continuously. But just placing a sensor on the side of a bridge doesn’t automatically lead to cost savings and a safer bridge.

Small towns, big flood waters
Climate change is bringing more water to people’s doorsteps, devastating communities. For some floodplain towns, survival comes down to sink, swim, or rise. Entire towns are moving to escape rising waters. But how do towns address these growing threats and still retain their sense of community? But how do you move an entire town? lood experts at UC Davis are visiting dozens of communities to find out. This is the story of two of those towns.

The U.S. drinking water supply is mostly safe, but that’s not good enough
Most Americans take clean drinking water for granted as a convenience of modern life. The United States has one of the world’s safest drinking water supplies, but new challenges constantly emerge. As a scientist specializing in water quality, I believe water providers and regulators can’t afford to be complacent.

Rising seas threaten Australia’s major airports – and it may be happening faster than we think
Most major airports in Australia are located on reclaimed swamps, sitting only a few meters above the present-day sea level. And the risk of sea level rise from climate change poses a greater threat to our airports than we’re prepared for. Given the significant disruption cost and deep uncertainty associated with the timing of sea level rise, we must adopt a risk-based approach which considers extreme sea level rise scenarios as part of coastal infrastructure planning.

Rural areas more vulnerable to sea-level rise
Type “sea-level rise” in an internet search engine and almost all the resulting images will show flooded cities. But there is a growing recognition that sea-level rise will mostly impact rural land–much of it privately owned—where existing knowledge is insufficient o best inform private and public decisions on how to cope with the threat.

Antibiotics found in some of the world's rivers exceed “safe” levels
Concentrations of antibiotics found in some of the world’s rivers exceed “safe” levels by up to 300 times, the first ever global study has discovered. Researchers looked for 14 commonly used antibiotics in rivers in 72 countries across six continents and found antibiotics at 65 percent of the sites monitored.

Coal-fired power plants may affect your drinking water
When you get a drink of water from your fridge or sink, do you think about where that water came from? A new study takes a national look at whether coal-fired power plants are unintentionally affecting drinking water treatment plants.

Can we prepare for climate impacts without creating financial chaos?
Likely sooner than we think, the destruction that warmer global temperatures are inflicting — through record floods, wildfires, droughts, and hurricanes — could physically overwhelm our ability to maintain many communities in their existing form. Communities face a tricky dilemma as climate changes: How to prepare for impacts without scaring away homeowners and investors and setting off a damaging economic spiral.

Google cuts Huawei access to Android software updates
Google said on Sunday it was rescinding Huawei’s license to use Google’s mobile phone operating system Android, and Google services such as Google maps and YouTube. The move will force the Chinese technology company to rely on an open-source version of the software. The move follows a presidential executive order prohibiting American companies from using telecommunications equipment made by “foreign adversaries” viewed as posing a threat to U.S. national security.

Why Huawei security concerns cannot be removed from U.S.-China relations
Huawei’s role in building new 5G networks has become one of the most controversial topics in current international relations. The U.S. is exercising direct diplomatic pressure to stop states from using the Chinese telecoms giant. The U.S. government regards Huawei as a clear and present danger to national security and argues that any ally opting for Huawei will compromise vital intelligence sharing among these countries in the future.

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
