Scientists create colourful brainbow images of the nervous system
— 31 Oct 2007 | BiologyBy activating multiple fluorescent proteins in neurones, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering their cells in a riotous spray of colours dubbed a 'Brainbow.' The technique is described in the cover story of the 1 November issue of the journal Nature by a team led by Harvard's Jean Livet, Joshua R. Sanes, and Jeff W. Lichtman…
Wildfire drives carbon levels in boreal forests
— 31 Oct 2007 | EnvironmentFar removed from streams of gas-thirsty cars and pollution-belching factories lies another key player in global climate change. Circling the northern hemisphere, the conifer-dominated boreal forests - one of the largest ecosystems on earth - act as a vast natural regulator of atmospheric carbon levels…
Space mission Xeus probes origins of the universe
— 31 Oct 2007 | AstronomyA University of Leicester astrophysicist is playing a pivotal role in a mission that seeks to study the origins of the universe. Professor Martin Turner of the Department of Physics and Astronomy is Co-Principal Investigator on XEUS - a next-generation X-ray space observatory…
New magnet design
— 31 Oct 2007 | PhysicsEngineers at Florida State University's National High Magnetic Field Laboratory have successfully tested a groundbreaking new magnet design that could literally shed new light on nanoscience and semiconductor research…
Breaking the silence
— 31 Oct 2007 | BiologyBrain scientists at Johns Hopkins have discovered how cells in the developing ear make their own noise, long before the ear is able to detect sound around them. The finding, reported in this week's Nature, helps to explain how the developing auditory system generates brain activity in the absence of sound. It also may explain why people sometimes experience tinnitus and hear sounds that seem to come from nowhere…
RIT study confirms supermassive black holes produce powerful galaxy-shaping winds
— 31 Oct 2007 | AstronomySupermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. The RIT team has, for the first time, observed the vertical launch of rotating winds from glowing disks of gas, known as accretion disks, surrounding supermassive black holes in the centres of galaxies. The findings are reported in the 1 November issue of Nature…
The smallest radio uses single nanotube to pick up good vibrations
— 31 Oct 2007 | PhysicsPhysicists at the University of California, Berkeley, have built the smallest radio yet - a single carbon nanotube one ten-thousandth the diameter of a human hair that requires only a battery and earphones to tune in to your favourite station…
Self-organising nanoparticles: a model for future nanofactories
— 31 Oct 2007 | PhysicsWith inspiration from bacteria and butterflies, researchers at Stockholm University have developed a new method that shows how nanomaterials can be produced in the future. In an article in the prestigious journal Proceedings of the National Academy of Sciences, Professor Lennart Bergstroem shows how a glass bottle and a simple hobby magnet can be used to produce and arrange extremely small cubes of iron oxide in a perfectly checkered pattern…
Green turtle nesting sites discovered in Senegal
— 31 Oct 2007 | BiologyA WWF survey has discovered several marine turtle nesting sites on the beaches of Senegal, prompting calls from conservationists to improve protection of the endangered species. The survey - conducted by WWF staff, Senegalese wildlife officials and the local community between July and September - discovered nine new green turtle nests on the beaches of Joal-Fadiouth in the Saloum Delta south of the capital, Dakar…
Hertfordshire astronomers gather new evidence about stars in our galaxy and distant quasars
— 31 Oct 2007 | AstronomyAstronomers from the Centre for Astrophysics Research at the University of Hertfordshire have provided the first evidence as to why stars are able to continue to accrete matter and grow, and how quasars can continue to fuel themselves preventing them from switching off. The results will be reported in two papers in the 1st November issue of Nature…
