Rafael Pablo Guillen Carmona, Director of Engineering of Sacyr Construction, has developed the launching gantry RPGC-21 to solve this very same problem at the Pamplona-Cúcuta project in Colombia.

A team of Hong Kong researchers has created a viscous magnetic slime capable of moving through narrow channels, transporting harmful substances and self-repairing. We look at why, despite its enormous potential to travel through the human body and avoid the need for invasive operations, it still has limitations and raises some open questions.

Built almost 100 years ago, at the height of the frenzied competition between major cities to have the world's tallest building, the Empire State Building remains a major tourist attraction in New York City. Long after being surpassed by others, it retains the aura that made it the headquarters of major companies and the setting for iconic films such as King Kong. We look back at why and analyse the energy efficiency challenges that await it in the 21st century.

While some scientists are trying to spread sunlight-reflecting materials onto polar ice caps to slow climate change, others plan to inject them into the stratosphere. Now a team of US researchers has a new goal: to find out whether seawater can be used to produce brighter, more reflective clouds that cool the planet.
