Article Synopsis
- Deep-sea hydrothermal vents, traditionally known for their chemosynthetic ecosystems, also potentially support phototrophic populations due to emitted light that may drive photosynthesis.
- Metagenomic analyses of samples from the Southwest Indian Ridge revealed widespread distribution of phototrophic bacteria, including known chlorophototrophs, and highlighted the presence of complete chlorophyll biosynthetic pathways.
- The findings suggest that geothermal vent light could provide energy that enhances the competitive advantage of phototrophs, supporting the idea of the ocean as a diverse microorganism seed bank.
A new flexible titanium foil cell for hydrothermal experiments and fluid sampling.
Rev Sci Instrum
September 2016
This paper describes the design of a flexible titanium foil cell, as well as its applications in hydrothermal experiments and in non-contaminating storage of seafloor hydrothermal fluids. A flexible cell constructed totally from pure titanium (Grade 1) can be used in corrosive environment because of the excellent chemical stability and temperature tolerance of the material. Theoretical calculation and finite element analysis of the titanium foil cell have been conducted to identify its flexibility and deformation mode.

Nrf2 is a transcription factor that mainly regulates the expression of a wide array of genes that produce the antioxidants and other proteins responsible for the detoxification of xenobiotics and reactive oxygen species. Nrf2 mediates the chemoprevention of cancer in normal cells.

Objective: To investigate the possible risk factors of severe acute respiratory syndromes coronavirus (SARS-CoV) infection in workers from animal markets.
Methods: Self-designed questionnaires were used and serum samples were tested. Logistic regression analysis was used to analyze the data.
Objective: To investigate status of infection with severe acute respiratory syndrome coronovirus (SARS-CoV) in traders of wild animals wholesale markets in Guangzhou.
Methods: Serum antibody against SARS-CoV IgG was determined cross-sectionally and symptoms of respiratory infection were investigated retrospectively for part of traders of three wholesale markets for wild animals in Guangzhou.
Results: Overall rate of infection with SARS-CoV in 635 traders was 16.
