According to a new study from the National Eye Institute, US, the risk of developing glaucoma, a common eye disease in senior people, was lower in those who drank hot tea on a daily basis.
A team of scientists analyzed data received from the 2005–2006 National Health and Nutrition Examination Survey, which included the medical data of nearly 10,000 people. Having analyzed the received data, the researchers discovered that the participant who drank hot tea every day had 74% lower risk of developing glaucoma.
However, the team concluded that further research is needed to establish the importance of these findings and whether hot tea consumption may play a role in the prevention of glaucoma.
According to a new research, a stem cell technology one day may restore sight to the blind people.
In this study, a group of scientists from the RIKEN Center for Developmental Biology, Japan, led by the researchers Masayo Takahashi and Michiko Mandai, wanted to test whether the animals’ vision can be restored. They placed mice in cages consisting of two rooms. The floor of one of the rooms was electrified at random points in time. Preceding each electric shock, the team flashed a warning light. To avoid the shock, the mouse had to see the light flash and move to the adjoining room.
The procedure managed to restore sight in nearly half of the mice with end-stage retinal degeneration. This success was due to the researchers’ choice of cells.
Masayo Takahashi explains: “It is still a developing stage therapy, and one cannot expect to restore practical vision at the moment. We will start from the stage of seeing a light or large figure, but hope to restore more substantial vision in the future.”
