Corrosion in metals can lead to the structural fatigue or failure of bridges, pipelines, and plane fuselages. Anti-corrosion coatings help prevent this, but they become ineffective when pierced, cracked, or scratched away. Researchers at Northwestern University have now developed a self-healing coating that can patch up its imperfections in a matter of seconds.
The Trump Administration is racing to field a new nuclear weapon designed to counter Russia and enhance nuclear deterrence.
The W-76-2 warhead will be delivered to the U.S. Navy for deployment on ballistic missile submarines in late 2019. Proponents claim the new warhead will enable the U.S. to respond to Russian nuclear weapons proportionately, but critics claim the W-76-2 is just another nuclear weapon and similarly dangerous.
As the United States becomes a net oil exporter for the first time in 75 years, the US Department of the Interior has announced the discovery of the largest continuous oil and gas field ever found. Situated in the Wolfcamp Shale and overlying Bone Spring Formation in Texas and the Permian Basin in New Mexico, the new resource is estimated to contain 46.3 billion barrels of oil, 281 trillion cu ft of natural gas, and 20 billion barrels of natural gas liquids worth trillions of dollars.
A new technique has been used to turn ordinary metals into “metallic wood” with a greatly improved strength-to-weight ratio. By manipulating materials at the atomic scale, scientists from the University of Pennsylvania’s School of Engineering and Applied Science, the University of Illinois at Urbana–Champaign, and the University of Cambridge claim to have created a sheet of nickel that is as strong as titanium, but up to five times lighter.
Beginning with the principles of the Stirling engine, SoundEnergy’s THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling without requiring any other power source. This completely renewable technology could prove highly disruptive.

A cure for cancer? Israeli scientists say they think they found one
Genetically modified bacteria could be used to treat liver and bowel diseases by mopping up toxins inside the gut.
Researchers tested the groundbreaking technique by creating a common strain of bacteria mop up excess ammonia in the body.
High levels of the chemical can be fatal for people with liver damage and rare genetic disorders.
