The sound of old garden birds is far away There’s a person who doesn’t come back I sat on the side of the road. *** How many green trees lộc Turn your back to me Only time left Give a sunrise every day. *** I pour the morning into a cup Pink finger spread time That’s it, an old appointment Has turned into mossy sediment… *** Thanks for the stay The hand that opens and closes the Sun The cup is full of sunshine I put a new day on my lips. Comments Ngo Thi Y Nhi’s poem has a unique feature in the four poems because of its different feelings about time. Normally, linear time, always passing, never comes back. Everything changes in the footsteps of time. Yet here, time stops with me, when everything passes. That sense of time is clearly contrary to the natural laws of the universe. Why so? As it turned out, the girl’s mood had determined the existence of time, changing the laws of nature. The hair is no longer green, the garden is old, the old people are far away, the oath has become mossy sediment… Who said time stops in those movements? Time still goes by! It’s just, I stay with my own great-grandchildren and comfort. The sun is still fragrant with the new day, the morning light still shines on each pink finger, why do you have to wither because of the old day? The poem ends with a beautiful picture: I put a new day on my lips . Life still gives us miracles, in every moment of time.

I understand I have to go Through the deep forest Through the whispering grass Through sunny areas Of the sad desert Through the tundra, the wind is fierce Where dreams are extraordinary I practice walking step by step Together or alone I keep myself breathing For a minute the hand let go I have a couple of appointments With a couple of souls Waiting for each other on the top of the snow Or at the end of the misty cloud I go and I know I don’t go alone There’s another me beside me Of a circle of wisdom Waking up every day We all have to go Even if there are days to lie down Wait for the pain to pass. Comments The poem “Go” by Nguyen Thien Ngan evokes a permanent idea of ​​the human journey. That journey carved the shadow of existence in time. We can visualize the destination as a dream, a wish, a projection. However, no one knows for sure that that destination will always be what they once thought. In the deep forests of the mountains, where the grass whispers, where the wind is burning in the tundra, where the desert burns … there are still many things hidden that you will never know when you leave. Journey makes life. Every moment is an existence. Therefore, the central quartet is “going out” with an extraordinary dream. Maybe, on that journey, we bring an appointment to accompany us, maybe it’s just loneliness with our own shadow. But, no matter what, still have to “go” as the fate of existence. Am I lonely? If unfortunately that is true, then “My side and I are different / Of a circle of wisdom”. The circle of wisdom is a clear awareness in the spirit of the truth of life, of the dream existing in the midst of life. The poem opens deep into the deep journey when the day after tomorrow we unfortunately lie down. Lying down is actually just the start of another journey!

The light-emitting glasses device helps visually impaired patients locate and touch the book on the table. (Source: nytimes.com) On May 24, a group of scientists announced that they had partially restored the vision of a blind man, by injecting light-sensitive proteins into one eye. The study was published in the journal Nature Medicine. This is the first study to describe the successful use of this new treatment. The patient participating in the trial of the new treatment is a 58-year-old French man who is completely blind due to retinitis pigmentosa. With the help of a special type of glass, he was able to see some objects from a narrow perspective such as notebooks, pin boxes, glass shards… The study’s authors say the trial – the result of 13 years of continuous work – has reached an important milestone for more effective treatments in the future. Dr José-Alain Sahel, an ophthalmologist at the University of Pittsburgh and the Sorbonne in Paris, said: “Clearly this is not the end of the road, but an important milestone.” Dr. Sahel and other scientists have been trying for decades to find a cure for inherited forms of blindness. These genetic disorders rob the eye of essential proteins needed for vision, causing the light-sensitive cells to degenerate. When light enters the eye, photoreceptors capture these rays. They then send an electrical signal to neighboring cells, called ganglion cells, which are responsible for transmitting information. vision from photoreceptors to the brain via the optic nerve. In previous studies, researchers were able to treat a form of genetic blindness known as Leber congenital blindness, by correcting a faulty gene that can cause photoreceptors to gradually become impaired. degenerate. But other forms of blindness cannot be treated so simply if the retina has completely lost its photoreceptors. “Once the cells are dead, you can’t fix the gene error,” says Dr. Sahel. For these diseases, Dr. Sahel and other researchers tested a new, more radical approach. They used gene therapy to turn ganglion cells into new photoreceptors, even though these ganglion cells normally don’t pick up light. Scientists are taking advantage of proteins derived from algae and other bacteria that can make neurons sensitive to light. Ed Boyden, a neuroscientist at the Massachusetts Institute of Technology (MIT) who is a pioneer in the field of optical genetics, thinks the use of proteins to cure blindness has taken him by surprise. “So far, I’ve only thought of optical genetics as a tool primarily for scientists, because it’s being used by thousands of people to study the brain,” he said. But if optical genetics were used for medical purposes, that would be extremely exciting.” Dr. Sahel and colleagues realized that the photogenetic proteins created by Dr. Boyden were not sensitive enough to produce images from normal light entering the eye. Amplified light also cannot be used to shine into the patient’s eyes, as this will damage the delicate tissues of the retina. So they selected a photogenetic protein that is only sensitive to amber light and inserted it into ganglion cells in the patient’s retina. Next, the researchers invented a special device that transforms visual information from the outside world into an amber light that the ganglion cells can perceive. They created goggles that scan the field of view at a rate of thousands of times a second and record any pixel where the light changes. The goggles then send a pulse of light from that pixel into the eye. The method can produce images in the brain, the researchers say. Our eyes naturally roam around in small movements many times a second. With each movement, these pixels change the light level. However, it is still an open question whether blind people can learn how to use this information to identify objects. About this Botond Roska said: “The brain has to learn a new language.” After testing gene therapy and goggles on monkeys, Dr Roska, an ophthalmologist at the University of Basel, co-author of the study, and colleagues are ready to test it in humans. Their plan was to inject the gene-carrying virus into the eyes of each blind volunteer who signed up for the new gene therapy, then wait a few months for the ganglion cells to develop the photogenetic proteins. They will then instruct the volunteers on how to use the goggles. However, they have only coached one volunteer due to the outbreak of the COVID-19 pandemic. The 58-year-old man has been wearing goggles at home and while walking. One day, he realized that he could see pedestrian lines on the road. When the pandemic subsided in France, scientists continued to test his eyesight and discovered that he could still reach and touch a notebook on the table, identifying swapped glasses. The results of the electroencephalogram (EEG) showed that his brain was indeed responding to the visual signals from the eye. Currently, Dr. Sahel and colleagues are bringing in other volunteers to test and further refine the new treatment technique.

Carefree waves erase The bird sends a song to the blue sky The wind brings into nothingness *** I’m noisy, sad, happy, sea biển Silently know who to send I haven’t cried yet, it’s already salty I’m not happy that the waves have melted *** The wind caressed the long silky hair Blue beach with love sign Blurry mountains look silver sea Clouds fly over the waves of thousands of years *** Looking for the footprints of the past The sea lullabies a white lullaby I met me in a frozen seashell Oh dear heaven and earth… Comments The general feeling of the poem is the nothingness, the dissolution of all things into the immense heaven and earth. Footprints in the sand, the song of the blue sky, the sign of love, happiness or sadness, noise or silence, like a wild song on the white tide. The perception of brevity and nothingness evokes in us thoughts of existence. Perhaps, standing in front of the blue mountains and the silver sea, one can see most clearly the smallness of human life. Where do we cry but the sea is already salty? Where am I happy that the waves have melted? Meeting yourself in a watery shell is a very suggestive image. That small heart contains the immensity of heaven and earth. Maybe it’s a consolation. On the journey to find traces of existence, the heart of the seashell shines into the sky and the shape of the sea, the blue shore, the yellow beach and the blue mountains. Does anyone hear, a sigh before nothingness!
