ORC as Loader of the Rings

Researchers have mapped the critical steps of DNA replication, revealing how a ring-shaped protein called origin recognition complex (ORC) initiates the process by slipping into a groove on DNA and initiating a cascade of microscopic interactions. The study provides new insights into an immensely complex system that is constantly ongoi...

Can North American animals such as rabbits, cows, or pigs serve as hosts for Zika virus?

A new study investigated the potential role of North American animals as hosts for Zika virus. Researchers tested common animal species, including goats, pigeons, raccoons, and ducks, for infectious virus presence and antibodies. The findings suggest that these animals may serve as an unseen reservoir for Zika virus in urban environments.

Hormonal maintenance therapy may improve survival in women with chemo-resistant rare ovarian or peri

Researchers found that hormonal maintenance therapy significantly improved survival in women with low-grade serous carcinoma of the ovary/peritoneum. Women who received HMT showed an average progression-free survival of 64.9 months, compared to 26.4 months for those in the surveillance group.

In great shape

Berger's Isomax material achieves low density and uncommon strength, making it suitable for various applications such as aerospace structures and robotic machines. The study's findings support the concept's potential for efficient fabrication and manufacturing.

Deep Learning predicts hematopoietic stem cell development

Researchers developed an algorithm that uses Deep Learning to predict the decision of hematopoietic stem cells to become a certain cell type. This enables earlier detection and analysis of blood cell development, paving the way for new treatments and insights into developmental traits.

Five studies in JAMA, JAMA Internal Medicine examine effect of testosterone treatment on various health outcomes in men

Studies published in JAMA and JAMA Internal Medicine found that testosterone treatment was associated with improved bone density and anemia in men with low testosterone. However, the studies also found no significant association between testosterone treatment and improved cognitive function or reduced risk of cardiovascular problems.
