C. albicans capable of sexual reproduction

Like many fungi and one-celled organisms, Candida albicans, a normally harmless microbe that can turn deadly, has long been thought to reproduce without sexual mating. But a new study by Professor Judith Berman and colleagues at the University of Minnesota and Tel Aviv University shows that C. albicans is capable of sexual reproduction.

Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

Scientists demonstrate how immortal flatworm overcomes aging process

Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal.

UC Riverside research could help prevent crop loss, pest outbreaks

New research by scientists at the University of California, Riverside shows that evolution - genetic changes in populations over time - can occur so rapidly in organisms that its impact on population numbers and other aspects of biology can be seen within just a few generations.

Primary function of sex is not to promote diversity, but to maintain a species' identity

Biology textbooks maintain that the main function of sex is to promote genetic diversity. But Henry Heng, Ph.D., associate professor in WSU's Center for Molecular Medicine and Genetics, says that's not the case.

Scientists discover special mechanism that delays ageing

Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of Gothenburg have shown how colony-forming ascidians can activate the enzyme telomerase, which protects DNA. This enzyme is more active also in humans who attain an advanced age.

Environment plays a key role in determining sexual over asexual reproduction

Evolutionary biologists at the University of Toronto (U of T) have found that environment plays a key role in determining whether a species opts for sexual over asexual reproduction.

Biomedical applications of 'warrior worms' in snails

Scientists at UC Santa Barbara have discovered a caste of genetically identical "warrior worms" -- members of a parasitic fluke species that invades the California horn snail. The findings are reported in the early online version of the Proceedings of the Royal Society B.

Ecological speciation linked to emergence of new fungal diseases in plants

A new commentary on the nature of pathogens is raising startling new questions about the role that fundamental science research on evolution plays in the understanding of emerging disease.

Manual provides laboratory methods, information and resources on new collection of model species

Mice, frogs, and E. coli are standard organisms in biology laboratories. But in the last few years, due in part to technical advances, the reduced costs of genome sequencing, and increased interest in evolution and development, the range of organisms used for research has greatly expanded. Scientists now have more flexibility in choosing a model system that might better address their specific research question.

New insights into yeast cells may help identify cancer cells and stem cells development: Study

Yeast cells decide whether to have sex with each other within two minutes of meeting, according to new research published today in Nature. One of the authors of the study, from Imperial College London, says the new insights into how yeast cells decide to mate could be helpful for researchers looking at how cancer cells and stem cells develop.

Sexual reproduction leads to lesser accumulation of harmful DNA mutations than asexual reproduction

Living organisms have good reason for engaging in sexual, rather than asexual, reproduction according to Maurine Neiman, assistant professor of biology in the UI College of Liberal Arts and Sciences and researcher in the Roy J. Carver Center for Genomics.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

Sexual reproduction and evolution

The utility of sex, according to an intriguing new theory of evolutionary biology, may be its ability to promote genes that play well with many other partners rather than those that shine with just one specific set of genes.

Researchers block the transmission of malaria in animal tests

By disrupting the potassium channel of the malaria parasite, a team of researchers has been able to prevent the malaria parasites from forming in mosquitoes and has thereby broken the cycle of infection during recent animal tests.

Surviving without sex - Bdelloid rotifers do!

Birds and bees may do it, but the microscopic animals called bdelloid rotifers seem to get along just fine without sex, thank you.

Study of planarians offers insight into germ cell development

The planarian is not as well known as other, more widely used subjects of scientific study , model creatures such as the fruit fly, nematode or mouse.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

Application from the Newcastle Fertility Centre at Life to make human embryonic stem cells

The Human Fertilisation & Embryology Authority (HFEA) is currently considering a licence application from the Newcastle Fertility Centre at Life to make human embryonic stem cells using cell nuclear transfer - a technique also known as therapeutic cloning.
