Exercise guidance available in MP3

Workouts such as Cardio Coach for MP3s are designed for a variety of cardiovascular activities, whether you`re outside on the trail or inside on a treadmill. During the 30 to 60-minute track, Cardio Coach founder and personal trainer Sean O`Malley offers listeners encouragement and motivation as they progress through a series of sprints.

In the past year, at least half a dozen companies have begun offering similar sessions for a variety of workouts. Companies such as iAmplify, iTrain and GYMP3, for instance, offer workouts that may guide listeners wearing an iPod or MP3 as they work out on a specific cardio machine or as they do reps on strength training equipment.

Programs like Cardio Coach and Podfitness may be downloaded for a fee while a free demo is available on the Podfitness Web site, which offers users the option of selecting their own music.

A team led by a University of Leicester forensic pathologist is believed to be the first in the world to use a new radiological approach for mass fatality investigation, reports EurekAlert. Traditionally two types of radiology are used in mass fatality and temporary mortuary investigations - that of fluoroscopy and plain x-ray.

These are time consuming, yield limited information and are a health and safety hazard to those working in the environment due to the use of radiological equipment. They are also not undertaken at the scene of the incident.

The university`s team used a mobile radiological system, a MSCT scanner, at the mortuary for the examination of the victims of a vehicle mass fatality incident. This instrument provided superior information in two-dimensional plain film and three-dimensional multi-slice examination with on-site soft tissue and bony reconstruction. The system proved faster than traditional temporary mortuary radiology, yielding greater information related to identification, health and safety, autopsy planning and cause of death.

Lakehead University in Ontario, Canada, has ruled out campus-wide wireless Internet access because its president fears the system`s electromagnetic forces could pose a risk to students` health, reports The Australian. The university has only a limited number of WiFi connections at present, in places where there is no fibre-optic Internet connection. "That is just fine," according to president Fred Gilbert.

"The jury is still out on the impact that electromagnetic forces have on human physiology," Gilbert said, insisting that university policy would not change while he remained president. "Some studies have indicated that there are links to carcinogenetic occurrences in animals, including humans, that are related to energy fields associated with wireless hotspots, whether those hotspots are transmissions lines, whether they`re outlets, plasma screens, or microwave ovens that leak," he said.

Robert Bradley, director of consumer and clinical radiation protection at Canada`s federal health department said there was no reason to believe that properly installed wireless networks pose a health hazard to computer users.
