Link between assisted reproduction techniques and genetic disruption
Evidence that assisted reproduction techniques may carry a risk of genetic 'imprinting disorders' in the resulting babies, emerges in a study published in the Journal of Medical Genetics. To assess the likely risk of genetic disruption, geneticists from the University of Birmingham and the West Midlands Genetics Service assessed the birth... view more... (2003-01-14)
Social life-history response to individual immune challenge of workers of Bombus terrestris: a possible new cooperative phenomenon
Solitary organisms can minimise fitness loss from parasitism with a facultative change to an earlier reproduction. Such a shift of the reproductive effort gives the host a chance to compensate for the cost on future reproduction resulting from the infection. In the case of social insects, where brood care and reproductive effort are shared between... view more... (2004-02-05)
Artificial night lighting jeopardises the survival of sea life
Artificial night lighting can jeopardise the survival of sea turtles by obliterating environmental cues. Writing in the August issue of Biologist, Mike Salmon, of Florida Atlantic University, USA, explains how artificial coastal lighting disturbs female sea turtles' navigation to nest beaches and disorientates their hatchlings so that many fail to... view more...

Study supports the use of mechanical assistance for acute or chronic heart failure in high-risk patients
The success of long-term implantable ventricular assist devices (LVAD) or artificial hearts has led to their increased use in patients previously thought to be unsuitable for mechanical support. This study documents the shift in the demographic profile of patients in need of artificial hearts to a more high-risk group. Looking at clinical records... view more... (2004-11-10)
First live rhinoceros birth from frozen-thawed semen
There may be less than 20,000 rhinoceros in the world, with one species perhaps already extinct and another with possibly only four animals remaining in the wild. view more (2008-11-13)

Sewage treatment plants fail to remove artificial sweeteners completely from waste water. view more (2009-06-18)
Reproduction of fungus depends on ...
A research team of the Department of Applied Chemistry of the University of the Basque Country has been studying the reproduction of funguses. In the laboratory of Unai Ugalde, they have studied and identified a molecule that is essential in the growing of fungus. It is already known that funguses grow in several places, but the factors that... view more... (2002-11-15)
Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals that help plants reproduce. Predation on pollinators... view more... (2003-08-13)
Shark skin saves naval industry money
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. view more (2005-07-18)
Children born after PGD as healthy as those born after conventional IVF treatment
Children born after embryo biopsy for preimplantation genetic diagnosis (PGD) do not show any more major malformations than those born after artificial reproduction technologies (ART) without PGD. view more (2007-06-18)
Press invitation: World's first cyborg visits University of Sussex
Kevin Warwick, Professor of Cybernetics at the University of Reading will give a talk entitled 'When will Cyborgs rule the World?' on Tuesday 28 May at the University of Sussex. Kevin Warwick hit the headlines most recently in March this year when he had electrodes inserted into his arm in order to link his nervous system to a computer. His... view more... (2002-05-23)
Age is more than a number — In barn owls, it reveals how susceptible one is to climate change
Fluctuations in weather and the environment affect survival and reproduction of animals. But are all individuals within a population equally susceptible? Theory on the evolution in age-structured populations suggests not - those life stages that are more important for overall fitness should be less susceptible to environmental variation than other... view more...

Researchers design artificial cells that could power medical implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants. view more (2008-10-09)
Early feeding could help reduce liver dysfunction in critically ill patients
Changing the way that critically ill patients suffering from sepsis or multiple organ failure are fed could reduce liver dysfunction. view more (2007-01-29)
Pregnancies from frozen eggs may help couples trapped by Italian law
Berlin, Germany: Five children have been born conceived from previously isolated and frozen egg cells, Italian scientists announced today (Wednesday 30 June 2004) at the 20th annual conference of the European Society for Human Reproduction and Embryology. The method bears great promise for patients who live in countries where embryo... view more... (2004-06-29)
Plastic-Protein Hybrids
Functional membrane proteins in a block copolymer matrix Biological membranes form a fluid matrix, in which proteins "swim". Many of these membrane proteins are of interest for both pharmacological and biotechnological applications - for example, they are under consideration as biosensors for the rapid screening of pharmaceutical agents.... view more...

Mechanical engineering helps research into the liver
Artificial glass livers being developed at the University of Leeds could help those suffering from liver failure, and improve understanding of how the organ works, researchers believe. Dr Peter Walker of mechanical engineering is leading Leeds' contribution to a three-year £320,000 project that aims to replicate the geometry of the liver,... view more... (2004-01-26)
Italy now faces worldwide storm of protest over fertility proposals
Italian legislators now face worldwide condemnation by fertility experts for IVF proposals that could encourage multiple pregnancies and put babies at risk. The International Federation of Fertility Societies (IFFS) has added its voice to that of the European Society of Human Reproduction and Embryology, who have already described the proposals as... view more...

Understanding Infertility - The Role of Genes in the Control of Reproduction
The problem of infertility is not confined to humans alone. There has been a noticeable decline in the reproductive ability of cattle that have been bred specifically for their high milk yields. Two scientists at Department of Animal Science and the Conway Institute of Biomolecular and Biomedical Research, University College Dublin have been... view more... (2003-01-21)
`Artificial vision` for recycling
The technological centre Robotiker from Zamudio (Basque Country) has developed a system of artificial sight to separate metals that come with copper, in order to obtain high purity copper. To recover copper from old cables it is not something new. However, the recycled copper is not pure, because it is mixed with other metals, such as lead,... view more... (2002-08-09)
