Researchers Study Hair To Track Perpetrators Of International Crime
A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo, Spain, have come up with a method to detect how the proportions of isotopes in a chemical element (atoms with an equal number of protons and electrons but different numbers of neutrons) vary throughout the length of a single hair. The mid-term objective is to be able to use these methods to track the geographical movements of people, including international crime suspects and victims.

Faster, Cheaper Genome Sequencing Featured At The 15-Minute Genome 2009 Industrial Physics Forum
In the race for faster, cheaper ways to read human genomes, Pacific Biosciences is hoping to set a new benchmark with technology that watches DNA being copied in real time. The device is being developed to sequence DNA at speeds 20,000 times faster than second-generation sequencers currently on the market and will ultimately have a price tag of $100 per genome.

Novartis Successfully Demonstrates Capabilities Of Cell-based Technology For Production Of A(H1N1) Vaccine
Novartis has successfully completed the production of the first batch of influenza A(H1N1) vaccine, weeks ahead of expectations. Cell-based manufacturing technology[1] allows vaccine production to be initiated once a pandemic virus strain is identified without the need to adapt the virus strain to grow in eggs, as with traditional vaccine technologies. This advance has cut weeks off the time required to begin vaccine production. This first batch of ten liters of wild type influenza A(H1N1) vaccine monobulk will be used for pre-clinical evaluation and testing and is also being considered for use in clinical trials. It demonstrates the value of the cell-based production approach, that is also being used by Novartis with reassortant influenza A(H1N1) seed.

Older People Benefit From Progressive Resistance Strength Training

Progressive resistance strength training not only helps older adults become stronger but also makes their everyday life easier, a Cochrane Review suggests. Muscle strength decreases naturally as people age. This reduction in muscle strength could affect older adults carrying out daily activities. Progressive resistance strength training is a type of strength training that uses free weights, exercise machines, or elastic bands to strengthen muscles. Key to this type of this exercise is adjusting the resistance, or weight, according to the person"s progress. This exercise can be prescribed to help older adults gain the strength necessary to carry out everyday activities such as walking, climbing stairs, bathing or doing housework. "Older adults seem to benefit from this type of exercise even at the age of 80, and even with some type of health condition. The data support the idea that muscle strength is largely improved after the training, and the impact on older adults" daily activities can be significant. Simply having enough strength to do things such as carrying groceries would make a difference for seniors" says lead researcher Chiung-ju Liu of the Department of Occupational Therapy at the Indiana University at Indianapolis in the US. The 121 trials reviewed in the study involved 6,700 people over the age of 60, who trained two to three times a week. Training produced a large improvement in muscle strength, a moderate to large improvement in doing simple activities such as getting up from a chair or climbing stairs and a small but statistically significant improvement in doing complex daily activities, such as bathing or preparing a meal. Severe adverse events were rare and most reported events were muscle soreness and pain. "We recommend older adults work with a health professional or an exercise professional to do progressive resistance strength training" says Liu. Because the long-term effect was not assessed in most trials, the Cochrane Researchers did not know how long the effects could last. Jennifer Beal Wiley-Blackwell
