Israeli Solution Prevents Bridge and Tunnel Disasters
People responsible for the health of bridges, tunnels and elevated highways can now see a real-time, cloud-based, 3D “medical report” thanks to technology invented at Israeli startup Dynamic Infrastructure. The company’s proprietary deep-learning image analysis compares daily images of the structure with older images extracted from past periodic inspections.

Should New York Build a Storm Surge Barrier?
It’s been seven years since Superstorm Sandy brought the city that never sleeps to a grinding halt. The Superstorm Sandy anniversary also marks seven years since New York started talking about building storm surge barriers to protect itself from future storms. At a recent event hosted by Columbia University, experts discussed a study that is evaluating the feasibility of building storm surge barriers around New York and New Jersey. The panelists also debated whether such a measure is a good idea.

Tensions Rise between Egypt and Ethiopia over Nile Dam Project
Tension is rising between Egypt and Ethiopia over the huge Ethiopian dam project on the Nile. Egypt is worried that the construction of the Renaissance Dam, a $4 billion dollars project launched by Ethiopia in 2012 and scheduled to start operations in 2022, will substantially reduce water flow in the Nile. Egypt depends on the Nile for about 90 percent of its water supply. Egypt insists on a guarantee from Ethiopia that Egypt would receive a minimum of 40 billion cubic meters of water annually, but Ethiopia argues that this would give Egypt an unreasonably large share of the Nile’s water.

Deflecting Massive Asteroids With a Nuclear Impulse
Researchers have completed the first ever in-depth investigation into how an asteroid would respond to a nuclear deflection attempt. “The whole purpose of studies like this is to help us shorten the response timeline if we were to see something coming at us,” said one researcher. “We don’t want to have to scramble to figure out whether to use an impactor or a nuclear device on a particular asteroid. These studies help us define those thresholds.”

PG&E Warns of Ten Years of Power Shut-Offs. California Officials Don’t Like It
California residents face up to 10 years of widespread, precautionary forced power shut-offs until Pacific Gas & Electric Corp., the bankrupt utility giant, will be able to prevent its power transmission lines from sparking fires, the company’s top official said. Howard Blume writes for the Los Angeles Times that the sobering projection came from company Chief Executive William D. Johnson at an emergency meeting Friday of the California Public Utilities Commission in San Francisco.

Patching Legacy Software Vulnerabilities Rapidly in Mission-Critical Systems
There are a vast number of diverse computing devices used to run the critical infrastructure our national security depends on – from transportation systems to electric grids to industrial equipment. While the amount of deployed vulnerable software is growing exponentially, the effective means of addressing known vulnerabilities at scale are limited. DARPA seeks to develop targeted software patches to rapidly repair legacy binaries in mission-critical systems, while assuring system functionality is not affected.

Whole-House Fire Blanket Protects Buildings from Short Wildfires
Wrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assesses this method of defense. Existing blanket technology can protect an isolated building from a short wildfire attack, but technological advancements are needed for severe fire situations.

With Coastal Waters Rising: First-Ever National Assessment of FEMA Buyouts
The Federal Emergency Management Agency has been offering voluntary buyout programs to homeowners in flood-prone neighborhoods since the 1980s. And with increasingly powerful storms battering coastlines and flooding becoming more ubiquitous after heavy rains, these programs and the idea of managed coastal retreat have continued to garner more and more attention. A new study is the first to examine nationwide data on FEMA’s buyout program.

Protecting critical infrastructure
Energy, water, food, fuel, information, transportation – ensuring a supply of these essential services and commodities is vital for a properly functioning society and economy. So essential, in fact, that we only realize their importance when suddenly they are no longer there. The infrastructure and systems that supply us with these assets are increasingly connected and, for this reason, highly vulnerable to natural disasters, accidents and criminal or terrorist attacks. In response, Fraunhofer is devising solutions and strategies to safeguard our critical infrastructure.

A First: U.K. Renewables Generate More Electricity than Fossil Fuels
In the third quarter of 2019, the U.K.’s windfarms, solar panels, biomass and hydro plants generated more electricity than the combined output from power stations fired by coal, oil and gas, a new analysis reveals. During the three months of July, August and September, renewables generated an estimated total of 29.5 terawatt hours (TWh), compared with just 29.1TWh from fossil fuels, the analysis shows. This is the first-ever quarter where renewables outpaced fossil fuels since the U.K.’s first public electricity generating station opened in 1882.

12 Hours. 4 Syrian Hospitals Bombed. One Culprit: Russia.
The Bashar al-Assad regime in Syria represents the Alawite minority (in 2011, about 75 percent of the Syrian population was Sunni , and about 12 percent were Alawites). Since the civil war in Syria began in 2011, the Assad regime, in the largest ethnic cleansing campaign since the end of the Second World War, has methodically, and successfully, pursued the goal of drastically reducing the number of Sunni Muslims in Syria. So far, the Assad regime has killed more than 500,000 Syrian Sunnis; has driven more than 5.6 million Sunnis out of Syria; and internally displaced more than 6.6 million Sunnis. One of the keys to Assad’s ethnic cleansing campaign has been the systematic destruction of hospitals and medical facilities in Sunni-majority areas and the killing of medical personnel. This strategy increases the number of dead and untreated wounded among the Sunnis, and along with the methodical destruction of water and sewage treatment facilities, makes life even more unbearable in Sunni areas of Syria. Since September 2015, the Russian air force has been doing most of the destruction of medical facilities and other civilian infrastructure in Sunni-majority areas.

Socioeconomic Effects of Coastal Flooding in California
Researchers are studying the impact of coastal flooding on disadvantaged communities in California. The effort, launched with funding from the National Science Foundation’s Coastlines & People initiative, will employ advanced simulation systems to deepen understanding of increasing flood risks within the state’s two most imperiled areas: Greater Los Angeles and the Sacramento-San Joaquin River Delta.

Supporting Coastal Communities Facing Changing Sea Levels, Coastal Flooding
Coastal communities and the surrounding ecosystems are threatened by rising seas and coastal flooding that alter shorelines making people, homes and businesses more vulnerable to coastal storms. Rising sea levels can also change how ecosystems work, especially when combined with inundation from tides and storms. With increasing threats to our coasts, enhancing resilience to sea level rise and flooding has become a national priority.
