Similarly, technology developers benefit from independent testing regimes that allow them to prove their products and trial them in combi...Abnormal fat metabolism underlies heart problems in diabetic patients
...causes the heart to use lipids for fuel. A 16-hour fast caused significant problems with the mouse hearts' ability to pump blood, again implicating altered lipid metabolism, cardiolipin scarcity and mitochondrial impairment in heart disease using lipid as predominant fuel. Gross adds that in addition to t...Why nectar-feeding bats need a 'power drink' to fly
...second experiment, Voigt and Speakman measured how fast the bats used their meagre fat stores. We found the bats depleted almost 60% of their fat stores each day, but even this phenomenal rate was still barely enough to sustain their metabolism when nectar was absent. This underlines how accurately these ...How cells change the pace of their steps
...ise found that cells without Talin moved nearly as fast as wild-type cells. The finding suggests that the rate at which a cell can tighten and relax its cytoskeleton is more important in controlling its speed than how firmly it attaches to the substrate. Different cell types in the body can move at diff...Nanotechnology helps scientists make bendy sensors for hydrogen vehicles
... sensing performance in terms of high sensitivity, fast response time and quick recovery, and the use of plastic sheets reduces their overall weight and increases their mechanical flexibility and shock resistance. The sensors are also able to be wrapped around curved surfaces, and this proves useful in ma...Rare example of Darwinism seen in action

... the United Kingdom are reporting development of a fast new fingerprinting method that shows promise for improving the collection and analysis of fingerprints from crime scenes. The finding is scheduled for publication in the August 1 issue of ACS Analytical Chemistry , a semi-monthly journal. Standard...Limpets reveal possible fate of cold-blooded Antarctic animals
...cold-blooded polar marine animals are incapable of fast growth. Until now scientists assumed that a lack of food in winter was the major limiting factor. Studies of the protein-making abilities of limpets in both the sea around the British Antarctic Surveys (BAS) Rothera Research Station and in the lab...Pediatric ritalin use may affect developing brain, new study suggests
...somewhat awry or the brain might be developing too fast -- these changes might help 'reset' that balance in a healthy way. On the other hand, in brains without ADHD, Ritalin might have a more negative effect. We just don't know yet." One thing was clear: 3 months after the rats stopped receiving Ritalin...Gene variant increases risk of blindness

AMD can take two forms called wet (also called chor...What determines the speed at which birds fly?
...very slow speeds among smaller birds and with very fast speeds for larger birds. They also show that the evolutionary history of the species helps explain much of the variation in flight speed: species of the same group tend to fly at similar characteristic speeds. For example, birds of prey and herons ha...Boosting key milk nutrients may help lower type 2 diabetes risk

Working with colleagues at the University of Michigan, the scientists used advances in technology to isolate nearly 200 proteins from the urine of patients with and without bladder cancer.
