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

The long view
The Potential Impact of Seabed Mining on Critical Mineral Supply Chains and Global Geopolitics
The potential emergence of a seabed mining industry has important ramifications for the diversification of critical mineral supply chains, revenues for developing nations with substantial terrestrial mining sectors, and global geopolitics.
