New Medicare program could dramatically improve affordability for cancer drugs – if patients enroll

A new voluntary program, the Medicare Prescription Payment Plan (MPPP), could greatly reduce out-of-pocket costs for Medicare patients taking expensive oral cancer drugs. By spreading annual costs across 12 monthly payments, patients can avoid large upfront payments and make treatment more affordable.

As a competitive grain for malting, rice may open door to increase domestic demand

Researchers found that using rice malt instead of milled rice in beer brewing can decrease production costs by 2-12%. Malted rice also requires less crop-growing acreage, making it a viable alternative for craft brewers. The study suggests that malting could open up new markets for Arkansas rice and ensure its long-run sustainability.

Edvard Westermarck’s Archives inscribed on the UNESCO Memory of the World Register, honoring his pioneering work in anthropology and sociology

The Westermarck Archives, stored at Åbo Akademi University Library, have been inscribed on the UNESCO Memory of the World Register. The collection contains correspondence, manuscripts, notes, and photographs from Westermarck's field studies in Morocco, providing insights into anthropology, sociology, and local cultures.

Cancer research reveals how chemo impact cells at the molecular level

Scientists have developed a cutting-edge technology to analyze protein turnover in individual cells, enabling them to identify treatment-resistant cancer cells and understand the impact of specific drugs. This breakthrough could lead to advancements in disease diagnostics and treatment strategies.

Immune cells drive congenital paralysis disease

A recent study published in Journal of Experimental Medicine found that immune cells play a major role in the development of spastic paraplegia type 15. The research, led by Professor Elvira Mass and Dr. Marc Beyer, suggests that severe inflammation in the brain precedes neuronal damage and could be relevant to Alzheimer's disease.

New research explains why our waistlines expand in middle age

Researchers at City of Hope discovered a novel target for preventing age-related abdominal fat by identifying the cellular culprit behind midsection widening in middle age. The study found that aging triggers the arrival of new adult stem cells and enhances the body's massive production of new fat cells, especially around the belly.

This injected protein-like polymer helps tissues heal after a heart attack

Researchers developed a new therapy that can be injected intravenously right after a heart attack to promote healing and prevent heart failure. The therapy both prompts the immune system to encourage tissue repair and promotes survival of heart muscle cells after a heart attack, showing effectiveness up to five weeks after injection.

Atomically dispersed catalysts are tough puzzles to solve, but worth the effort

Researchers are developing atomically dispersed catalysts to make industrial processes cleaner and more efficient. However, the field is plagued by common pitfalls, including inadequate testing and characterization. Experts like Jason Bates and E. Charles Sykes emphasize the need for repeatable, rigorous science.

IGTP-led study identifies an epigenetic signature with prognostic value in metastatic thyroid cancer

A study led by IGTP identifies an epigenetic signature of 156 altered CpG sites in primary tumours that can help stratify patients according to their risk of developing distant metastases. The findings contribute to a better understanding of the disease and open new avenues for patient stratification and personalised treatment strategies.
