“This engine is grinding to a halt” - Nature slowing down as climate change gains pace

A new study from Queen Mary University of London finds that species turnover in ecosystems has significantly slowed down despite accelerating climate change. This slowdown is attributed to environmental degradation and the depletion of regional life pools, suggesting a loss of momentum in biodiversity.

Why only a small number of planets are suitable for life

A study found that only planets with medium-level oxygen conditions during core formation can retain essential elements phosphorus and nitrogen, necessary for life. This limits the number of potentially habitable planets, as most solar systems have stars with different chemical compositions.

Mayo Clinic study finds chemotherapy before surgery improves survival in early-stage pancreatic cancer

Researchers found that when pancreatic tumors touch the superior mesenteric vein, patients who undergo surgery first experience reduced survival rates. In contrast, those who receive chemotherapy before surgery have similar survival outcomes to those with non-vein touching tumors. The study suggests reclassifying tumors based on vein i...

Does a vegetarian upbringing stunt growth?

A landmark study of nearly 1.2 million infants suggests that a vegan or vegetarian diet does not compromise infant growth by age two. The research found that infants from plant-based households follow growth trajectories nearly identical to their omnivorous peers, providing reassuring evidence for parents and pediatricians.

Deterministic entanglement-assisted quantum communication over 20-km fiber channel

A team of scientists experimentally demonstrated deterministic entanglement-assisted quantum communication over 20.121 km in fiber channels, outperforming classical communication in metropolitan areas. They proposed an improved continuous-variable dense coding scheme to enhance transmission efficiency and reduce excess noise.

Unveiling the oxygen usage of catalysts to eliminate greenhouse gases views​

Researchers at KAIST have identified a new principle for catalyst design that allows ceria to selectively use different oxygen sources depending on the reaction environment. By adjusting the size of the catalyst, it can choose whether to use oxygen from the air or store it internally.

AI & big data: IPK research team improves predictions for ‘tailor-made’ wheat

The IPK research team developed a prediction model using large datasets, genomic markers, and environmental information to forecast wheat yield in specific locations. The model achieved improvements of up to 23% in predicting new hybrid performance, similar to getting a tailored suit that fits the environment.

Mount Sinai scientists uncover link between influenza and heart disease

The study found that a novel subset of white blood cells becomes infected in the lung and produces type 1 interferon, which triggers cardiac damage. A modified mRNA treatment was shown to mitigate cardiac damage while preserving the immune system's protective response. The research offers great promise for developing new therapies to p...

Let’s get on pancreatic cancer’s nerves

Scientists found that tumor-promoting fibroblasts attract nerve fibers through a vicious cycle of signaling and neurotransmitter release. This cycle promotes pre-cancerous growth and pulls in more nerve fibers, leading to a self-reinforcing loop. Disrupting this cycle may lead to new therapies for pancreatic cancer.
