Subordinate male cichlid fish who help with the childcare for the dominant breeding pair are occasionally actually the fathers of some of the offspring they help to rear, according to new research from the University of Bristol published today in PLoS ONE. This sneaky paternity increases the subordinate fish´s investment in the offspring in their care. The highly social cichlid fish Neolamprologus pulcher, endemic to Lake Tanganyika in Africa, live in social groups consisting of a...

New research has found that stem cells derived from human cord blood could be an effective alternative in repairing heart attacks. At least 20 million people survive heart attacks and strokes every year, according to World Health Organization estimates, but many have poor life expectancy and require continual costly clinical care.  The use of patient´s own stem cells may repair heart attacks, although their benefit may be limited due to scarce availability and ageing.  The...

Early Screening, Treatment Of HIV Yields Impressive Gains In Life Expectancy
2011-10-12 10:06:48

People currently living with HIV can to live 15 years longer using improved HIV treatments over the past decade or so, according to a new study published in the British Medical Journal today.  Earlier diagnosis combined with timely treatment can increase life expectancy. Although life expectancy for HIV patients remains less than in the general population, dramatic progress in reducing side effects from drugs, offering them as combination therapies and earlier treatments have helped...

Findings could pave the way for more effective tissue repair treatments Scientists have discovered how cells detect tissue damage and modify their repair properties accordingly. The findings, published today [6 October] in the journal Developmental Cell, could open up new opportunities for improving tissue repair in patients following illness or surgery. The Wellcome Trust-funded study, led by biochemists at the University of Bristol, examined the signaling process in damaged tissue...

New research, led by psychologists at the University of Bristol, has found that children who are familiar with a snack food will expect it to be more filling. This finding, published (online ahead of print) in the American Journal of Clinical Nutrition, is important because it reveals one way in which children over-consume snack foods and increase their risk of becoming overweight. Children are at risk of obesity due to consumption of energy-rich snack foods that are often high in calories...

New research has found public sector workers are typically more pro-socially motivated than their private sector counterparts. The University of Bristol study, published today [21 Sep], examined motivational indicators in workers from both sectors across 51 countries. But there are some nations where the reverse is true and the Economic and Social Research Council (ESRC)-funded study, led by academics in the University's Centre for Market and Public Organisation, explored whether...

Warming Seas Affect European Fish Stocks
2011-09-16 12:45:27

  The first "big picture" study of the effects of rapidly rising temperatures in the northeast Atlantic Ocean shows that a major shift in fish stocks is already well underway. But it isn't all bad news. The research, published Sept. 15 in Current Biology, shows that some fishes' losses are other fishes' gain. The study led by Dr Steve Simpson of the University of Bristol in collaboration with researchers from eight other institutions, is the first to combine a suite of European...

Diamonds Show Carbon Cycle May Reach Earth's Lower Mantle
2011-09-16 10:41:51

  By studying the chemistry of an unorthodox set of Brazilian diamonds, a team of researchers have discovered startling new information about the carbon cycle and the theory of plate tectonics. Researchers from the University of Bristol, Universidade de Brasilia, and the Carnegie Institution for Science studied what are known as "superdeep" diamonds, some of which originated from depths of 435 miles (700km) or more before erupting to the surface as volcanic rocks. Most diamonds...

The levels of violence girls and boys from disadvantaged backgrounds experience in their partner relationships is revealed in new University of Bristol research published today. It is the first time there has been an in-depth look at violence in the intimate relationships of disadvantaged teenagers who are not in mainstream education. Some of those who took part had been permanently excluded from school, were young offenders or teenage mothers. The researchers interviewed 82 boys and...

Meteorites May Have Brought Precious Metals to Earth
2011-09-08 04:20:54

  Precious metals such as gold, platinum and tungsten were brought to Earth by a massive meteorite shower that occurred approximately 650 million years after the planet formed, scientists from the University of Bristol revealed on Wednesday. According to a university press release, researchers Dr. Matthias Willbold and Professor Tim Elliott of the university's School of Earth Sciences, studied nearly four billion year old rock samples recovered from Greenland. The samples, which...
