The Lancet Respiratory Medicine: First UK Biobank genetic study reveals new associations with lung disease and smoking behavior

A new UK Biobank study has identified six independent genetic variants associated with lung health and chronic obstructive pulmonary disease (COPD). The findings also suggest that genetic variations affecting gene regulation may play a role in COPD, providing potential targets for novel therapeutic strategies.

Hormonal therapy may prevent ovarian failure and preserve fertility in breast cancer

Researchers found that adding hormonal treatment during chemotherapy reduced the risk of premature ovarian failure by 45% and increased pregnancy rates among young breast cancer patients. The use of LHRHa could be a potential standard strategy to preserve ovarian function and fertility in hormone receptor positive breast cancers.

Blocking light improves preemies' survival rates

Researchers found that shielding parenteral nutrition from light significantly decreases oxidative stress and cell damage in premature infants, improving their survival rates. The study's findings suggest a potential solution for reducing mortality rates in preterm infants born between 26-31 weeks of gestation.

The Lancet Oncology: Tackling the global shortfall in radiotherapy could save millions of lives and boost the economy of poorer countries

A global shortfall in radiotherapy resources has led to millions of unnecessary deaths, but investing in radiotherapy services could bring economic benefits of up to $365 billion over the next 20 years. Access to radiotherapy is currently unacceptably low, especially in Africa, where most countries have no facilities.

Everolimus improves progression-free survival for patients with advanced, nonfuctional neuroendocrine tumors

The study found that everolimus improved progression-free survival by 52% and increased median progression-free survival by over seven months in patients with advanced, nonfunctional neuroendocrine tumors. The treatment was well-tolerated, with common side effects including aphthous ulceration, rash, diarrhea, fatigue, and infections.

A different type of 2-D semiconductor

Researchers successfully grew atomically thin 2D sheets of organic-inorganic hybrid perovskites from solution, exhibiting efficient photoluminescence, color-tunability, and unique structural relaxation. The ultrathin sheets have square-shaped geometry, high quality crystallinity, and large size, facilitating their integration into futu...

Plants with jobs

Two University of Toronto scientists developed a new research framework to measure agricultural impacts using functional trait-based ecology. The approach focuses on how plants respond to and affect changes in their environment, providing insights into crop diversity, nutrient cycling, pest repellence and drought mitigation.

Deep-diving whales could hold answer for synthetic blood

Researchers found that deep-diving whales have ultra-stable versions of myoglobin, a protein that holds oxygen in muscle cells. This stability allows them to pack more myoglobin into their cells, enabling them to remain active while holding their breath. The discovery could lead to creating synthetic blood for human trauma patients.

Having the 'right' connections only gets you so far

A study of 1,298 NFL coaches found that junior coaches with connections to highly reputable head coaches are more likely to receive promotions. However, these connections do not lead to superior career outcomes in the long term, and instead favor those who missed out on initial advantages but excelled through merit.
