Why is there higher cancer mortality in indigenous Polynesian peoples?
Indigenous Polynesian populations face higher cancer mortality rates due to factors like smoking, obesity, and limited access to screenings. Screening programs for breast cancer cover less than half of Pacific women compared to European New Zealanders.
Emissions irrelevant to future climate change?
A new study published in Carbon Balance and Management found that the link between carbon cycle and human-induced emissions may only be relevant for several centuries. The research suggests that even weak but continuing emissions can lead to eventual saturation of climate-carbon cycle feedback, regardless of when emissions peak.
Epigenetic research uncovers new targets for modification enzymes
A team of scientists has identified new non-histone targets for a protein methyltransferase enzyme, expanding our understanding of epigenetic regulation in cells. The discovery broadens the view on methyltransferases and indicates that epigenetic gene regulation is more complex than previously thought.
Even part-time work can have a negative effect on breastfeeding rates, says new study
A recent Australian study found that part-time and casual work among new mothers has a significantly negative impact on breastfeeding rates, almost as big as returning to full-time work. The lack of paid maternity leave and workplace support for breastfeeding are cited as major factors contributing to this finding.
Gene therapy improves vision in patients with congenital retinal disease
Researchers have successfully used gene therapy to restore vision in three young adults with a rare form of congenital blindness. The study showed significant improvements in visual acuity and sensitivity to light, setting the stage for further studies.
Exeter engineers create new technique for malaria diagnosis
Researchers have created a new technique for diagnosing malaria that could be as effective as current rapid diagnostic tests but far faster and cheaper. The method uses magneto-optic technology to detect haemozoin, a waste product of the malarial parasite, in blood samples.
Looking at neurons from all sides
Scientists have developed a new technique to study neurons in three dimensions, allowing for faster analysis of neuronal activity and interactions. This breakthrough uses a fast-moving laser beam and multi-photon microscopy to provide a more detailed understanding of neuron function.
