  Danish Tycho Brahe was most famous for his contributions to astronomy. However, he also had a well-equipped alchemical laboratory where he produced secret medicines for Europe's elite.
• Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution July 25, 2024
  An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.

• Scientists identify key protein behind spread of shingles virus July 25, 2024
  Scientists have discovered a new evasion strategy used by the varicella zoster virus, which causes chickenpox and shingles, that may allow it to affect tissues far from the original site of infection.
• In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment July 25, 2024
  Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The […]
• Great Salt Lake a significant source of greenhouse gas emissions July 25, 2024
  Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due […]
