New microscopy to observe bacterial
Thorough understanding how bacteria infect cells is crucial in preventing many human diseases. In what is a crucial advance in microscopy, has recently discovered a new way to study molecules in their natural environment.
This new approach could be the key to know in detail the complex process by which bacteria infect humans. So far, traditional approaches for studying the processes of infection have focused on observing the cells involved either individual molecule within of them.
The natural mechanism that protects against stroke damage to a certain class of neurons
It has been possible to identify a natural protective mechanism in some neurons at the onset of stroke. The results of the investigation that led to this finding could be used to develop treatments aimed at protecting other types of neurons, responsible for speech and movement.
The stroke, the third leading cause of death in the United Kingdom and other countries, disrupting the blood supply to the brain deprived of oxygen and nutrients to the affected cells.
Improve the technical quality of the optical disc technology through the eyes of a crustacean
The eyes of the stomatopod have led an international team of researchers to develop a device that could improve the holographic technology and the CD, DVD and Blu-ray, allowing definitions and achieve even higher storage densities.
These marine crustaceans found in the very short list of animals that can see circularly polarized light, as used in 3D movies. Some researchers believe that the eyes of stomatopod are better for the entire visual spectrum than any man-made devices of the type based on the action of a transparent block which can alter the polarization of light because it has a double refraction.
The plant ‘calling’ bats
European researchers have discovered a tropical plant (Marcgravia evenia), which is pollinated by bats, has developed a parabola-shaped leaves with great resonance. The results, which are now published in Science, show that the pollinators feed on nectar and flowers can be found two times faster than through echolocation.
Bees and birds are guided visually to pollinate flowers with bright colors. But there are signs that attract bioacoustics other pollinators such as bats and allow the dispersal of seeds? Until now little was known about the subject.
Terrestrial plants with stomata complex much earlier than believed
The control of water loss is an important capacity of existing terrestrial plants, allowing them to thrive in changing environments. New research shows that biological innovations relating to the conservation of water occurred very early in the evolutionary history of plants.
Research has focused on the role of the stomata, microscopic pores on the surface of the leaves that capture carbon dioxide gas for use in photosynthesis, while allowing the release of water.
Healthier, more beautiful skin eating fruit and vegetables
Eating fruit and vegetables in abundance is the most effective way to healthy skin and a sexy shade skin, according to the conclusions reached by a team of researchers.
In countries like the UK, most people think that the best way to have a more attractive skin tone is tan in the sun or under UV lamps, but research conducted by Dr. Ian’s team Stephen (University of Bristol) shows that eating plenty of fruit and vegetables is actually more effective.
The team, which has conducted his research at the Perception Laboratory at the University of St Andrews, Scotland, first assessed the tone of the skin of Caucasians in relation to their diet. Those who ate more servings of fruit and vegetables per day was also having a golden skin tone.
Improved Flood Forecasting With a New Technique in Satellite Images
Using images taken from satellites hundreds of kilometers above the earth’s surface, a team of researchers are exploring the risks of flooding in some of the largest regions in the world. It is expected that the data used may be freely available for use in every task undertaken to provide more immediate responses to natural disasters.
Revision of Old Cases of Murder By means of the modern techniques of DNA identification
The University of Bristol has been involved in the proposed revision of a murder case in the context of a scientific program to apply modern techniques of DNA identification by reviewing old crimes in which such techniques were not used and on which there is reasonable doubt that the convicted person might actually be innocent.
The case in question is that of Neil Hurley, who is serving a life sentence for the murder of Sharon Pritchard.
Delving into the Causes of Traffic Jams Strangers
Sometimes, people traveling on a road that runs into a traffic jam is not motivated not by works on public roads, either by accident or by an influx of vehicles greater than normal. After a while, these phantom jams end as mysteriously as it began.
One line of research, which now the University of Bristol has begun work on a new project and found that although most of the changes in vehicle speed and its position on the road are absorbed by the flow of traffic, sometimes combined in a “perfect storm” to create these phantom jams.
In dense traffic conditions, the action of a single driver who crosses a rail car to another is enough to cause a “small snowball that grows as it spreads from the vehicles driving behind into a” great snowball that ends with a traffic jam.
