Visualization of the molecular gateway across and into cellular membranes All living organisms are made up of cells, behind these intricate life forms lie complex cellular processes that allow our bodies to function. Researchers working on protein secretion – a fundamental process in biology – have revealed how protein channels in the membrane are activated by special signals contained in proteins destined for secretion. The results help explain the underlying mechanism...

Scientists Announce World's First Magnetic Soap
2012-01-24 10:55:27

University of Bristol scientists have developed a magnetic soap that could potentially one day be useful in oil spills and revolutionize cleaning products. The soap is produced by dissolving iron in a range of inert surfactant materials composed of chloride and bromide ions -- much like those found in mouthwash or fabric softener. This means the soap and the materials that it dissolves can be readily removed by applying a magnetic field. Experts believe with further experimentation and...

Scientists have shown that a new molecule in the earth´s atmosphere has the potential to play a significant role in off-setting global warming by cooling the planet. In a breakthrough paper published in Science, researchers from The University of Manchester, The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of Criegee biradicals. These invisible chemical intermediates are powerful oxidisers of pollutants such as nitrogen dioxide...

New research hopes to explain premature births and failed inductions of labor. The study by academics at the University of Bristol suggests a new mechanism by which the level of myosin phosphorylation is regulated in the pregnant uterus. The researchers, Dr Claire Hudson and Professor Andrés López Bernal in the School of Clinical Sciences and Dr Kate Heesom in the University Proteomics Facility and the School of Biochemistry, have discovered that phosphorylation...

Diabetes is a major risk factor for cardiovascular disease and can reduce blood supply to the heart tissue and damage cardiac cells, resulting in heart failure. New research has investigated if nerve growth factor (NGF) gene therapy can prevent diabetic heart failure and small vascular disease in mice. The study by Professor Costanza Emanueli, British Heart Foundation Senior Research Fellow and colleagues of the Bristol Heart Institute in the Regenerative Medicine Section of the School of...

Intensive agriculture practices developed during the past century have helped improve food security for many people but have also added to nitrate pollution in surface and groundwaters. New research has looked at water quality measurement over the last 140 years to track this problem in the Thames River basin. The NERC-funded study, led by the University of Bristol's Department of Civil Engineering, has looked at nitrate transport from agricultural land to water in the Thames basin. The...

Computer Algorithm Predicts Hit Songs
2011-12-19 06:08:38

Researchers are using science to help the recording industry predict whether or not a song will becoming a radio smash hit. A team from the University of Bristol's Intelligent Systems Laboratory says that predicting the popularity of a song may be feasible by using state-of-the-art machine learning algorithms. They looked at the official U.K. top 40 singles chart over the past 50 years, in an attempt to distinguish the most popular songs from the less popular songs. The researchers...

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories. The findings, published today [13 Dec] in the...

New research has looked at whether social media could be used to track an event or phenomenon, such as flu outbreaks and rainfall rates. The study by academics at the University of Bristol's Intelligent Systems Laboratory is published online in ACM Transactions on Intelligent Systems and Technology. Social networks, such as Facebook and microblogging services like Twitter, have only been around for a short time but in that time they have provided shapshots of real life by forming,...

Cannabis use is associated with disturbances in concentration and memory. New research by neuroscientists at the University of Bristol, published in the Journal of Neuroscience [Oct. 25], has found that brain activity becomes uncoordinated and inaccurate during these altered states of mind, leading to neurophysiological and behavioral impairments reminiscent of those seen in schizophrenia. The collaborative study, led by Dr Matt Jones from the University's School of Physiology and...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
