Scientists Design Water Controlling Surfaces

Scientists design water controlling surfaces, according to news@nature and New Scientist, 30 August 2005. Scientists at the Massachusetts Institute of Technology (MIT), Boston have developed a spongy surface coating that reduces reflections and prevents glass from fogging. The coating consists of layers of glass nanoparticles, polymer fibres, and air bubbles. This combination attracts water but […]

Science Copies Beetle Sprayer

Science copies beetle sprayer writes Thomas F. Heinze: “Remember the bombardier beetle, famous for firing hot toxic fluid at its enemies through a squirter in its bottom? Science News informs us that this beetle: “is inspiring designers of engines, drug-delivery devices and fire extinguishers to improve spray technologies. It could also provide a much more […]

Prototype Gecko Glue

Prototype gecko glue developed by scientists at University of California, Berkeley according to Nature Science Update 28 August 2002. Geckos are small reptiles that can cling to any surface at any angle (including upside-down) because their feet have thousands of microscopic spatula shaped bristles that can form temporary atomic bonds, called van der Waals forces, […]

Polymer Platelets for Leaky Pipes

Polymer platelets for leaky pipes described in New Scientist, 23 December 2006, p29. A technology company in the UK is developing polymer blobs that can form a temporary plug on leaking pipes in a similar way that platelets help stop blood leaking from damaged blood vessels. The blobs can be introduced into the pipes upstream […]

Honeycomb Engineering

Honeycomb engineering revealed in a report in PNAS, vol. 107, p9502, 25 May 2010. The geometrical structure of honeycomb has long been recognised as superb engineering. The hexagonal structure makes a light but strong structure. However, natural honeycomb has been discovered to have strength, flexibility and tolerance of temperature changes that the geometry alone cannot […]

Bone Inspired Steel

Bone inspired steel made, as described in Science (AAAS) News and New Scientist 9 March 2017 and Science doi: 10.1126/science.aal2766, 10 March 2017. Metal fatigue is the weakening of a metal structure when it is repeatedly subjected to forces (“load cycling”), leading to the formation of microscopic cracks, as happens where aeroplane wings move up […]

Designer Yeast Chromosomes

Designer yeast chromosomes reported in Science, vol. 355, pp1024-1025 doi: 10.1126/science.aam9739, 10 March 2017. Several international teams of scientists have made five artificial chromosomes of a yeast cell. This is part of a massive ongoing project to make synthetic life. A summary of the current state of the research is headed “Yeast Genome, by Design” […]

Natural Insecticide Recreated

“Natural Insecticide Recreated in the Lab” is the headline of an article in Biology News Net, 23 Aug 2007. A team of British scientists has made a compound named azadirachtin, a substance that inhibits the development of a numerous destructive insects, but does not harm beneficial insects such as bees and ladybugs. The compound occurs […]

Artificial Bug Eye

Artificial bug eye made according a report in ScienceNOW 27 April 2006 and Science vol. 312 p557, 28 April 2006. Biophysicists at the University of California, Berkeley have made an artificial compound eye by making a dome of a light sensitive polymer covered with tiny bulges. They then shone ultra-violet light onto the dome so […]
