The cells that make up turbinate-homing IgA-secreting are located in the nasal lymphoid tissues
A study has found that mucus-resident IgA-secreting cells originate in nasal lymphoid tissues. Researchers said this helps to distinguish the germinal centres within Peyer’s patches from the nasal lymphoid tissue. T cells with IgA class switch recombination occurring before germinal centre formation are restricted to the nasal lymphoid tissues, the study said.

There are different types of memories in the human upper airway
Evidence of an “arsenal” of immune cells capable of fighting off respiratory infections can be reliably detected in the upper airways of young adults and older people, said researchers from the University of Melbourne in Australia. The structures act as a training camp for the B cells, which are the primary cause of the immune system’s weakness.

Read MoreScientists may have found dark oxygen being created
Researchers from the UK have found that polymetallic nodules on the seafloor, which contain metals that can be used for electric vehicles and consumer electronics, produce high levels of oxygen. Polymetallic nodules range in size from a small particle and about the size of a potato. Scientists believe they may be producing oxygen through an electrical charge generated by the nodules.

Read MoreThe first fossil chromosomes were found in the frozen mammoth skin
Researchers at Baylor College of Medicine in the US have discovered the 3D structure of an ancient genome of a tropical elephant’s skin. The DNA was preserved in a glass-like state through a dehydration process similar to that used to produce beef jerky. Previously thought impossible, researchers discovered chromosomes preserved in their original 3D configuration in samples of the animal’s skin.

Scientists are editing the genes of gutbacteria in mice
Researchers have found a hormone that helps build up bones in mice and make them stronger when producing milk. They injected the hormone into injured mice, and they found that it helped them heal faster. They hoped that injecting this hormone into injured mice helped their bones heal faster, and will help treat osteoporosis in humans.
