Medical experts have devised a novel means of preventing the occurrence of denture stomatitis among aging individuals. The approach centers on the use of a soft polymer gel, which is applied to the fitting surfaces of the denture to create a polymeric cushion effect on the denture. This procedure actually prevents inflamed tissues from rubbing with each other, thereby mitigating chances for acquiring infection.

Scientists have developed innovative methods to repair spinal injuries. Lars Olson of Karolinska Institute in Stockholm, Sweden, based his peripheral nerve grafts technique on the fact the peripheral nerves, which are located outside the brain and spinal cord, can regenerate after being damaged. Olson said that Schwann cells produce growth factors which diffuse towards the severed nerve ends and encourage the nerves to grow back.

The article profiles English physicist Peter Higgs. Higgs predicted the existence of a particle that has been named Higgs boson which, according to him, helps explain the origin of mass for some of the fundamental building blocks of matter. He was awarded the Dirac medal and prize in 1997 and the Wolf prize in 2004. Higgs taught theoretical physics at University College London and the University of Edinburgh.

This article discusses the need for militaries to change its culture of blame in order to avoid friendly fire accidents. There is no dispute that high-tech equipment can foster friendly fire accidents. The American and British forces in Iraq use thermal or radar images to engage the enemy at maximum range in limited visibility, says Scott Snook, former head of the Center for Leadership & Organizations at the West Point military academy in New York. Several new rules and steps are taken by the military to avoid such friendly fire accidents, but to no avail. INSET: DEATH IN THE SKIES.

The article focusses on consequences of the loss of Columbia space shuttle on not only the US space programme but also for the future of crewed space exploration. On March 1 , 2003 the space shuttle Atlantis was to have delivered the Multi-Purpose Logistics Module designed for transferring cargo onto and off the station, and the External Stowage Platform, to supply additional storage space. Although NASA has been insisting in recent years that science is at the forefront of its space programme, its partners in the project have complained about proposed budget cuts that would have shrunk lab space and cut the station's permanent crew from seven to three. Even before the accident, science experiments were being squeezed off shuttle schedules.

The articles discusses the use of a PC and a webcam to carry out multiple medical diagnostic tests in the comfort of one's home. The computer screens emit crisp and bright colours and hence they are pure enough to be used in diagnostic tests. Simply holding a grid of samples and reagents up to a computer screen that is displaying a sequence of colours and using a webcam to analyse the light that passes through the grid will make it easy to carry out several tests at once. However, a team of physicists led by Daniel Filippini at Link-ping University in Sweden reckon there is a far easier way.
