First demonstration of a multicore fiber network With optical fiber networks gradually approaching their theoretical capacity limits, new types of fibers such as multicore fibers have been at the focus of worldwide research to overcome critical capacity barriers, which threaten the evolution of the Internet. The University of Bristol in collaboration with the National Institute of Information and Communications Technology (NICT) have demonstrated successfully for the first time a multicore...

New research from the Children of the 90s study at the University of Bristol suggests that fish accounts for only seven per cent of mercury levels in the human body. In an analysis of 103 food and drink items consumed by 4,484 women during pregnancy, researchers found that the 103 items together accounted for less than 17 per cent of total mercury levels in the body. Concerns about the negative effects of mercury on fetal development have led to official advice warning against eating too...

It is common for parents to influence mate choice — from arranged marriages to more subtle forms of persuasion — but they often disagree with their children about what makes a suitable partner. A new study has found an evolutionary explanation for why some parents try to control who their children pair up with. The study, involving a University of Bristol researcher and published today in the journal Evolution & Human Behavior, shows that this conflict over mate choice may be...

New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas. Iceberg production and melting causes 2,800 cubic kilometers of ice to leave the Antarctic ice sheet every year. Most of this is replaced by snowfall but any imbalance contributes to a change in global sea level. For many decades, experts have believed that the most important process...

Researchers Develop Multi-Party Computation Security Protocol

Peter Suciu for redOrbit.com – Your Universe Online Last year, researchers in the United States and Europe reported finding an unexpected vulnerability in the encryption system commonly used to provide privacy and security for online shopping and banking websites, but now new research into cryptography could result in more secure computing. A new, collaborative study that was conducted between the University of Bristol and Aarhus University could result in changes in securing...

Removing one of the tiniest organs in the body has shown to provide effective treatment for high blood pressure. The discovery, made by University of Bristol researchers and published in Nature Communications, could revolutionize treatment of the world's biggest silent killer. The carotid body — a small nodule (no larger than a rice grain) found on the side of each carotid artery — appears to be a major culprit in the development and regulation of high blood pressure. Researchers,...

End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world. However, new research conducted by the University of Lincoln, the National Museum in Bloemfontein, South Africa, and the University of Bristol suggests that the end can also be the beginning. This research, which was published this month in the Proceedings of the Royal Society B, noted that the ancient closest...

Birds Help Solitary Lemurs Avoid Danger

April Flowers for redOrbit.com - Your Universe Online The Madagascan Sahamalaza sportive lemur (Lepilemur sahamalazensis) is an endangered species that scientists know very little about. A new study, led by the University of Bristol reveals that the sportive lemur uses the alarm calls of birds and other lemurs to warn it of the presence of predators, the first time this behavior has been observed in a nocturnal and solitary lemur species. Prior to this study, scientists knew that the...

Scientists show potential impact of therapy in reducing transmission in UK, Canada and Australia Around 150 million people globally are chronically infected with the hepatitis C virus (HCV) — a major cause of liver disease and the fastest growing cause of liver transplantation and liver cancer. 1 New prevention strategies are urgently required as people are continuing to be infected with HCV. Findings, published in Hepatology, reveal the impact of a new antiviral treatment that could...

Large helpers (nannies) in a cichlid fish allow the dominant male and female to reduce their personal contribution to their offspring and territory, according to new research published today in Functional Ecology. By removing the large helper for 30 days — which corresponds to one breeding cycle in this species — a team from the University of Bristol and the University of Bern (Switzerland) studied the investment strategies of the dominant pair and the survival of their brood,...
