New genetic clues for schizophrenia

Researchers found that de novo mutations, genetic errors present in patients but not their parents, are more common in schizophrenic patients. This discovery may help define how the disease results from these mutations and develop new treatments.

Pigeons never forget a face

Researchers found that pigeons can recognize individual people using facial characteristics, even when wearing different clothing. This ability is likely an adaptation to their long association with humans, enabling them to distinguish between individuals.

Synthetic collagen from maize has human properties

Researchers have successfully produced synthetic collagen in maize with similar levels of proline hydroxylation to human collagen. This breakthrough enables the production of a protein with human-like modifications, making it suitable for various applications in reconstructive and cosmetic surgery, as well as the food industry.

JCI online early table of contents: May 16, 2011

Researchers have identified a stem cell population that can reverse nerve cell loss in individuals with Parkinson disease. Protein-based human induced pluripotent stem (iPS) cells were found to efficiently generate functional dopamine neurons and treat a rat model of the disease. These findings suggest a potential new treatment approac...

Getting to the root of fatty liver disease

A new study has identified a molecular switch, TBL1, that appears to be a common feature in the development of fatty liver disease. The discovery is consistent with data from human patients and suggests an underlying explanation for the condition.

Progress toward the clinical application of autologous induced pluripotent stem cells and gene repair therapy for treatment of familial hypercholesterolemia

Researchers successfully reprogrammed diseased human hepatocytes into induced pluripotent stem cells, offering a potentially unlimited source for liver disease treatment. This breakthrough could enable the generation of genetically corrected liver cells via auto-transplantation, avoiding liver transplants and immunosuppression.

New research suggests that obesity and diabetes are a downside of human evolution

A new genetic discovery suggests that the loss of function in a human-specific gene called CMAH may contribute to the development of Type 2 diabetes. The study found that mice with this gene mutation developed insulin resistance and pancreatic beta cell failure, leading to decreased insulin production and impaired blood glucose control.

Figuring out fetal alcohol syndrome in fruit flies

Researchers used fruit flies to study fetal alcohol syndrome, finding that prenatal alcohol exposure can cause developmental problems such as intellectual disabilities and abnormal facial features. The study establishes a new model system for studying FAS, which may lead to the development of new therapies.

Genetic study uncovers new path to Polynesia

A new genetic study has found that the DNA of current Polynesians can be traced back to migrants from the Asian mainland who settled in islands close to New Guinea around 6,000 years ago. The research challenges previous theories on human migration, suggesting a 'voyaging corridor' between Southeast Asia and the Pacific

What sex are you?

A team of researchers has determined that overexpression of the Sox3 gene in mice causes frequent XX male sex reversal. Genomic rearrangements in the human SOX3 gene have been found in three patients with XX male sex reversal, suggesting a significant cause for this condition.

New research from Psychological Science

Researchers discovered that when a person's personality matches the prevalent personalities of others in a culture, it enhances positive effects on self-esteem and well-being. Additionally, social threats induce bodily freeze-like behavior in humans, while cultural differences in spatial representations affect time perception.

Genetic alteration linked with human male infertility

Researchers discovered a genetic alteration in the NR5A1 gene that disrupts sperm production, accounting for approximately 4% of cases of unexplained male infertility. The study suggests that these mutations may indicate mild abnormalities in testicular development, highlighting the need for further clinical investigation.

OU study on genetics in fruit flies leads to new method for understanding brain function

University of Oklahoma researchers have developed a new method for understanding brain function in humans, leveraging advances in genetic techniques to manipulate small subsets of brain cells. This breakthrough has significant implications for studies of human neurological diseases, including Alzheimer's and Parkinson's disease.

Mother of all humans lived 200,000 years ago

A new statistical method confirms that mitochondrial Eve, the mother of all humans, lived around 200,000 years ago. The study compared 10 human genetic models and found that they produced similar estimates, suggesting that refining assumptions beyond a certain point is not crucial in capturing the big picture.
