Scientists develop self-healing surface material
The human skin, when scratched or cut, heals quickly, in most cases leaving no trace of a scar after just a few days; German scientists develop surface material with similar qualities

Glass fibers can make a building sturdier
Conventional means to reinforce concrete involve the use of steel bars; the use of fiber reinforced polymer (FRP) is emerging as a valuable option, owing to its natural resistance to corrosion, its high strength, light weight, transparency to electrical and magnetic fields and ease of manufacturing and installment

New fire-resistant coating materials developed
Aussie researchers develop HIPS — Hybrid Inorganic Polymer System — coating; it can withstand temperatures of more than 1,000°C compared to current commercial coatings used on building materials and structures, which break down between 150-250°C

New bullet proof vests will be made from cement
University of Leeds researchers say that vests made of cement would offer cost-effective level of protection for many people at risk; it should be good enough for people like security guards, reporters and aid workers who are worried about the odd pot shot being taken at them

DARPA looking for Genesis-style AI lifeforms
DARPA has issued a solicitation for ideas about self-organizing Tetris AIs and smart-vat superlife on cards; the research organization appears to be seeking nothing less than the creation of artificial intelligent lifeforms

Building sturdier structures in hurricane-prone areas
The hurricane season is upon us; an architecture professor offers tips on how to build — and how not to build — sturdier structures in hurricane-prone regions

Researchers find ways to slow down deformation of concrete
Concrete is used in practically all forms of construction — buildings, bridges, tunnels, dams; trouble is, it deforms and crumbles over time; MIT researchers discover the reasons for the gradual deformation of concrete, a discovery which will lead to concrete infrastructures capable of lasting hundreds of years rather than tens

Glass-based coating for reinforcement bars for sturdier infrastructure
Researchers develop glass-based coating for reinforcement bars that helps prevent corrosion and strengthens the bond between steel and concrete; the material could help engineers build stronger bridges and increase the longevity of other steel-reinforced structures

Boat made from carbon nanotube composite fibers for coastal security
The administration’s 2010 budget cuts the U.S. Coast Guard’s budget, so it is good that a Washington state-based company is building a boat made entirely with carbon nanotube enhanced pre-impregnated composite fibers; the 16 meter boat will weigh less than 3,630 kg, fully equipped; this is approximately 75 percent less than fiberglass boats of the same size, and 33 percent less than conventional carbon fiber boats

Mechanical stress leads to self-sensing in solid polymers
Fighting Illini researchers develop force-sensitive polymers; when pushed or pulled with a certain force, specific chemical reactions are triggered in the mechanophores; such polymers may be used in aircraft components or bridges to report damage and warn of potential component failure, slow the spread of damage to extend a material’s lifetime, or even repair damage in early stages to avoid catastrophic failure

Silk tougher and lighter than steel
German scientists develop a technique to make silk tougher and lighter than steel — and even more elastic than spider’s silk; material may be used in surgical threats, bullet proof vests, and artificial tissue

Self-healing concrete for safer, durable, and cheaper-to-maintain infrastructure
Wolverines researchers develop self-healing concrete; the concrete self-heals itself when it develops cracks; no human intervention required — only water and carbon dioxide

One-story masonry building withstands strong jolts during seismic tests
University of California, San Diego researchers design a one-story masonry structure and showed it could survive two days of intense earthquake jolts

The long view
Could Deep Sea Mining Break China's Grip on Critical Minerals?
Mining companies have proposed to use remote-controlled robots or seabed crawlers tethered to surface ships to bring up nodules. The International Seabed Authority has wrestled for more than two decades with how to regulate seabed mining. The Trump administration has promised no such delay. It plans to use an existing U.S. regulatory framework.
