Amanda Williams published EDT 13: 07, March 26, 2013 | update: EDT 03:35, March 27, 2013, as the UK will speed up the clock and prepare for the summer, japanese experts may have designed solutions for one of their most terrible problems --hay fever.
Scientists at the forestry and forest products Institute have announced that they have successfully developed the first pollen and allergyCedar for free.
They say they are able to create regions by changing the genetic recombination process of plant DNA structure --
A particular tree that does not produce pollen.
Ishii Katsuaki Ishii, who led the study, said that although American scientists have created pine trees without pollen, this has never been achieved before in cedar.
Complete pollen
The free tree is still in the experimental phase,
Pollen trees have been planted all over Japan.
According to ABC News, the data recorded the growing pollen fever in recent years.
In the past 30 years, the number of people suffering from pollen fever in Japan has tripled.
One out of every four people in Japan now suffers from pollen fever every year, and this year the number of pollen has been particularly high-five times higher than last spring.
The researchers attributed this to the sudden rise in temperature, the hot summer of last year, and the large amount of cedar --
Called "sugi ".
After World War II, a large number of trees were planted to help post-war
The war-building boom.
Since then, the demand for wood has declined and the trees have matured, so more pollen will now be produced.
However, Japanese retailers have been harvesting the benefits of a surge in pollen numbers, including surgical masks,-
Pollen glasses, nasal plugs, nasal sprays and portable air purifiers that can be worn around the neck.
At present, one out of 8 people in the UK has moderate or severe hayfever symptoms.
From June to July, the amount of pollen is usually high.
Pollen is a powder released by plants as part of the reproductive cycle, containing proteins that cause swelling, inflammation and inflammation of the nose, eyes, throat and sinus.
There is no way to treat pollen fever at the moment, but most people are able to relieve symptoms through treatment, at least to a certain extent.
