Nanoparticles for optimized cancer therapy
Nov 15, 2023 (Nanowerk News) Pancreatic cancer is one of the deadliest types of cancers in humans. It is the fourth leading cause of cancer-related deaths in the western world. The early stages of the disease often progress without symptoms, so diagnosis is usually very late. Another problem: Advanced tumors...
‘Never witnessed before’ – Astronomers baffled by repeat explosions 100 billion times the energy of the Sun
Nov 16, 2023 (Nanowerk News) Astronomers are baffled by a mysterious and extremely bright event in the distant Universe, nicknamed the “Tasmanian Devil”, which has been observed to explode repeatedly and emit more energy than hundreds of billions of stars like our Sun. The report, published in Nature ("Minutes-duration optical...
Breakthrough in human liver organoid technology advances liver research
Nov 16, 2023 (Nanowerk News) For decades, scientists have faced substantial challenges in developing robust experimental models that accurately mimic human liver biology. Traditional cell lines and animal models often fail to replicate key aspects of human hepatic structure and function. This limitation has hampered progress in unraveling the molecular...
The universe is expanding faster than theory predicts
Nov 15, 2023 (Nanowerk News) Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth. Key Takeaways The universe is expanding at an accelerating rate, faster than current cosmological models predict, a...
