| Pangolin trafficking: Nigeria’s illegal trade Posted: 04 Nov 2021 05:14 AM PDT With Asian species dangerously depleted, global black markets have turned to Africa, and Nigeria has become the continent's pangolin trafficking 'hub'. Just Nigeria-linked pangolin seizures in the last decade alone amount to at least 800,000 -- but possibly close to a million -- animals, according to a new study. The findings suggest that current global estimates for pangolin trafficking are far too small, say researchers. |
| Experimental drug boosts immunotherapy effectiveness in pancreatic cancer in mice Posted: 04 Nov 2021 05:14 AM PDT An experimental drug enhanced the benefit of an immunotherapy to fight pancreatic cancer in mice by increasing the number of immune cells in the immediate vicinity of the tumor, leading to a reduction in tumor growth, and in some mice, eliminating their cancer. |
| Laboratory will illuminate formation, composition, activity of comets Posted: 03 Nov 2021 12:08 PM PDT Researchers have developed a laboratory to simulate comets in space-like conditions. The goal of the Comet Physics Laboratory is to understand the internal structure of comets, as well as how their constituent materials form and react. Many of the lab's future experiments will involve creating sample comet materials with differing compositions. By testing those materials in the space-like chamber, the researchers can compare each sample to what has been observed on actual comets. |
