The Lancet Oncology: For new HPV DNA test, study finds there may be little benefit in screening women aged 55 with a negative test

A new modeling study suggests that older women who test negative for human papillomavirus (HPV) with a DNA test may be at low risk of cervical cancer and could safely stop screening. However, regular cytology screening up to age 75 can still prevent cancers and is recommended for countries using HPV testing.

Reproducing pediatric kidney disease from human iPS cells

Researchers have successfully developed kidney tissue that exhibits the early stages of congenital kidney disease using iPS cells from a patient with a nephrin mutation. The study found that repairing the nephrin mutation can normalize abnormalities and may lead to the development of effective drugs for kidney disease.

UMass Medical School study safely delivers RNAi-based gene therapy for ALS in animal model

A new study by UMass Medical School researchers successfully delivers RNAi-based gene therapy to silence SOD1 protein mutations linked to ALS without adverse effects. The therapy, delivered via a viral vector, achieved silencing of over 90% in some motor neurons, suggesting a safe and potentially one-time treatment for humans.

New study found deep sea chemical dispersants ineffective in Deepwater Horizon oil spill

Researchers analyzed data from the BP Gulf Science Data and found no correlation between subsea dispersants and deep plume formation, showing substantial amounts of oil continued to surface. The study suggests alternative strategies such as the 'capping stack' method and bio-surfactants may be more effective in managing blowouts.

Could bariatric surgery make men more virile?

A review of 28 studies found that bariatric surgery increased testosterone levels and improved erectile function in obese men, but had no impact on sperm parameters. However, nutritional malabsorption may counterbalance these hormonal changes.
