Entomologists have discovered that there are far more insects flying around above our heads than previously thought. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place at Cardiff University on 12–13 September 2002, Dr Jason Chapman will say that in a typical summer month, around 3.5 billion insects fly over a square kilometre. This equates to one tonne of insects flying over Hyde Park in London, or Trelai Park in Cardiff, every four weeks in summer.
Scientists from Imperial College London and King’s College London have identified a molecule that helps to wire up the neural circuitry responsible for controlling the movement of muscle.
Writing today in the journal Neuron, the researchers describe how the signalling protein named WNT-3 directs specific neurons during embryonic development to make the correct connections in the spine to form a neural pathway that controls muscle.
Using mice, which offer the closest model to human
Highly Active Antiretroviral Therapy, or HAART, is the standard of care for HIV/AIDS patients and has prolonged the lives of countless persons with the disease. HAART has been associated, however, with the emergence of lipodystrophy syndromes. In this months issue of the journal Mitochondrion*, researchers from the National Cancer Institute (NCI), the National Institute of Standards and Technology (NIST), and Purdue University, West Lafayette, Ind., report that protease inhibitors, a component
In the quest to repair damaged DNA – a process believed crucial in combating ailments ranging from cancer to aging – antioxidant has been the Holy Grail. But findings published this week in Nature suggest oxidation isnt always the enemy.
Scientists at Michigan State University, along with colleagues in England, have uncloaked a mechanism that uses oxygen to repair DNA – until now an unlikely part of the restorative recipe. Their work is published in the Sept. 12 issue of the British sc
Working with guinea pigs, Johns Hopkins scientists have created what is believed to be the first biologic pacemaker for the heart, paving the way for a genetically engineered alternative to implanted electronic pacemakers. The advance, reported in the Sept. 12 issue of Nature, uses gene therapy to convert a small fraction of guinea pigs heart muscle cells into specialized “pacing” cells.
“We now can envision a day when it will be possible to recreate an individuals pacemaker cel
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency (ESA) hopes to get to the very bottom of it.
Scientists will study space phenomena that do not seem to conform to our perceived understanding of gravity. In this way, they hope to develop a greater comprehension of the Univ
