Problems with two-wheeled suitcases!

Holiday times are here! Do you own a two-wheeled suitcase? If so, you have probably experienced the problem of it rocking alarmingly from side-to-side when you drag it along. Scientists have come up with a solution: don’t slow down but speed up instead! Alternatively, you can lower the handle of the suitcase as close to the ground as possible. Alternatively, why not just buy a four-wheeled suitcase!

Goggles which give surgeons X-ray vision

An augmented reality system is being developed which will allow surgeons to put on goggles to look inside a patient’s body without opening them up. The system uses MRI and CT scans to build up a 3D image of the inside of a patient’s body, with different organs automatically colour-coded by software.

Graphene to desalinate sea water?

Another use for graphene! Graphene, which is composed a single layer of carbon atoms arranged in a hexagonal lattice, was produced in 2004 by a team lead by Manchester University. Now another UK based team have created a sieve made from graphene, which can remove  salt from seawater.

 

A wood in Staffordshire!

An interesting experiment is taking place in a Staffordshire forest. An area of the woodland has been cordoned off and the trees within the site are being subjected to high levels of carbon dioxide. The project has been set up to measure how trees will deal with the higher levels of CO2 in that are expected in the future.

Planes made of graphene?

Remember graphene, the single layer of carbon atoms forming a regular hexagonal pattern, which is very light but extremely strong? Richard Branson believes that aircraft could be made entirely of graphene in 10 years time.
