The benefits of olive oil for health and wellbeing

Research suggests that oleic acid in olive oil has antioxidant properties, inhibiting the expression of proteins associated with cholesterol transport, and reducing atherosclerosis. Additionally, oleic acid is recognized as an anti-cancer molecule, which also displays hypocholesterolaemic effects and may influence epigenetic mechanisms.

Oncotarget | Oncogenic driver FGFR3-TACC3 requires 5 coiled-coil heptads for activation and disulfide bonds for stability

Researchers identify the minimum contribution of TACC3 for FGFR3-TACC3 fusion protein activation, revealing a novel target for treating FGFR translocation-driven cancers. The study shows that clinically identified FGFR3-TACC3 fusion proteins differ in biological activity depending on specific breakpoints.

Leptin helps hungry mice choose sex over food

Researchers found that leptin receptor neurons prioritize social interaction over eating and drinking in moderately hungry mice. This system can only regulate moderate hunger, but not strong hunger, which may contribute to why diets don't work.

New study demonstrates inferior vena cava (IVC) filters are safe and effective way to treat venous thromboembolism (VTE)

Researchers found that IVC filters were effective in preventing pulmonary embolisms (PE) in patients with deep vein blood clots, even when used prophylactically. Approximately half of the patients had their filters removed without complication or recurrence of DVT or PE.

Scientists unlock key to drought-resistant wheat plants with longer roots

Researchers at the University of California, Davis, have discovered a key to improving drought-resistant wheat plants by stimulating longer root growth. By increasing the copies of specific genes, plants can absorb water from deeper supplies, leading to increased biomass and higher grain yield.

A human interactome to prioritise drug discovery

Researchers created a network of interacting proteins to understand the function of genes and link specific biological processes to diseases. They identified groups of proteins interacting with genes linked to over 1,000 human traits, providing insights into new targets for drug discovery and potential repurposing opportunities.

The 2020–2021 prolonged La Niña evolution in the tropical Pacific

Recent research has shed light on the prolonged La Niña events in the tropical Pacific, which have significant implications for global weather and climate. The study found that the sea surface temperature evolution is determined by a competition between local and remote effects due to subsurface thermal anomalies.

New treatment regimen may decrease mortality in patients with cardiotoxicity from immune checkpoint inhibitors

A new treatment regimen combining high-dose abatacept and ruxolitinib has shown to significantly improve survival rates among cancer patients with cardiotoxicity from immune checkpoint inhibitors. The experimental treatment reduced myotoxicity-related mortality by 90% compared to standard-of-care corticosteroids.
