Hybrid strains make insidious parasite more dangerous

Researchers at Karolinska Institutet in Sweden have mapped how the parasite Trypanosoma cruzi forms new variants that are more effective at evading the immune system and causing disease. Their findings can give rise to new ...

Human egg cells are imperfect surprisingly often

More than 7% of human oocytes contain at least one exchangeless chromosome pair, demonstrating a remarkably high level of meiotic recombination failure, finds a study appearing December 10 in the American Journal of Human ...

Natural gene therapy for intractable skin disease discovered

Pathogenic gene mutations causing a type of intractable skin disease can be eliminated from some parts of patients' skin as they age, according to Hokkaido University researchers and their collaborators in Japan. This represents ...

Human protein produced in CHO-cells can save donor blood

Alpha-1-antitrypsin is a protein produced by the liver. The protein gets secreted to the blood stream, where it circulates the body to protect the lungs. However, some people are born with genetic disorders that hinders production ...

Bat cave study sheds new light on origin of SARS virus

Genetic recombination between viral strains in bats may have produced the direct evolutionary ancestor of the strain that caused a deadly outbreak of severe acute respiratory syndrome (SARS) in humans, according to new research ...
