AI eye test for heart disease

ByJustpaste.in

A new study suggests that a simple eye scan could help predict a person’s risk of having a heart attack or stroke over the next 10 years.

The scan takes a picture of the back of the eye a test that is already used to check for different eye diseases.  Researchers believe it may also reveal important signs about heart health.

Scientists used artificial intelligence (AI) to study thousands of digital eye images.

The AI system can examine a scan in less than a second and estimate a person’s future risk of serious heart problems.

Researchers hope this quick test could one day become part of regular health checkups along with blood pressure and cholesterol tests.

This may help doctors identify high risk patients earlier and start treatment before serious problems develop.

The study focused on eye scans from people with type 2 diabetes because they already receive regular eye exams to detect conditions such as diabetic retinopathy.

Lead researcher Dr. Efi Mordi said the eyes can provide valuable information about the heart.

If the tiny blood vessels at the back of the eye become narrow or damaged similar changes may also be happening in the blood vessels that supply the heart.

At first the AI was trained to look for signs of narrowed or blocked blood vessels.

Later it also learned to recognize other small details such as the pattern and size of blood vessels.

The system was trained using 4,200 eye images.

The results were encouraging.  The AI correctly predicted the risk of a heart attack or stroke within the next 10 years with about 70% accuracy.

Dr. Mordi said the eye scan takes less than a minute and is already part of routine eye examinations. If widely used it could help save lives by identifying people who need early treatment.

Professor Bryan Williams of the British Heart Foundation called the technology an important step forward but said more research is needed before it becomes a standard medical tool.

Dr. Clare Jonas from the Stroke Association also welcomed the findings.

She said that if governments include technologies like this in healthcare planning they could help prevent many cases of stroke in the future.

Experts believe this research is an important development and could lead to  AI powered eye scans becoming a routine part of future medical checkups.

    A simple comment from his wife inspired a Chinese man to transform a barren valley into a huge garden filled with colorful flowers. The 80-acre valley is located in Chengdu, Sichuan Province China. Today it has become a beautiful flower filled home for Zhao Xiaolin and his wife, Yin Zai. A promise inspired by his wife Zhao got the idea in 2013 when his wife talked about her childhood memories in Beijing and shared how much she loved flowers. Her words inspired him to create a garden where she could enjoy flowers every day. He promised to turn the idea into reality. He had no gardening experience Zhao had no professional experience in gardening. Despite this, he sold his home bought land in a town called Zhuanlong and began learning how to grow flowers on his own. Over the years he collected seeds from different parts of China and other countries. He continued working on the land for more than a decade. From empty land to a flower paradise After years of hard work Zhao completely changed the landscape.  The area is now being described as one of the world’s largest hollyhock flower gardens. The garden is open to the public and contains more than 700 varieties of hollyhocks.  It is also home to around 150,000 lilies and 100,000 Chinese hibiscus plants. A love story that lasted 35 years Zhao says his wife and flowers are the two most important things that make his life beautiful. The couple has been married for 35 years and does not have children. They now share their life with several cats and dogs. Even after all these years they continue to exchange handwritten letters on birthdays and other special occasions. What started as a simple conversation about flowers eventually became a remarkable garden and a lasting symbol of their love.

  • Gustav Klimt’s “Lakeshore with Birches” (1901)

    ByJustpaste.in

    Gustav Klimt’s Lakeshore with Birches (Seeufer mit Birken, 1901) presents a contemplative immersion into nature. This piece was painted during a crucial transitional moment in Klimt’s artistic development. It was completed when Klimt spent his summers away from the urban noise of Vienna at Lake Attersee. This work captures the quiet rhythm of the natural world, distilled through a distinctly modern visual sensitivity. What immediately distinguishes Lakeshore with Birches is its unorthodox composition. Rather than offering a traditional panorama with a distant horizon line, Klimt deliberately truncates the viewer’s field of vision. The composition is anchored by a singular birch trunk rising vertically near the center-right of the canvas. Klimt creates a radical sense of spatial compression by eliminating the sky. The landscape is flattened into a decorative field, where depth is suggested through subtle layering. A lush, wild embankment dotted with small yellow and purple wildflowers. The stark pale birch trunk with its rhythmic dark lenticels, acting as a structural mast. In the background, still water reflecting the dark foliage of the far shore. This croppings draws inspiration from both Japanese ukiyo-e woodblock prints and contemporary square-format photography. The canvas forces the viewer to engage with the textures and moods of the immediate environment. The atmosphere of the painting is dictated by a restrained palette. Dominated by muted moss greens, deep olive tones, and dark murky browns, the water acts as a mirror absorbing the weight of the forest shadows. Against this dark, reflective pool, the small specks of yellow buttercups and delicate purples along the grass introduce a subtle optical vibration. Klimt’s brushwork here bridges French Impressionist techniques and the emerging principles of Art Nouveau. The bank is rendered using tiny, stippled dabs of paint, creating a tapestry-like surface pattern. Up close, the reflections on the water resolve into abstract patches of blue, gray, and dark brown. The slender birch tree provides a crisp, pale contrast. Its bark painted with precise horizontal dashes that echo the linear motifs Klimt would later deploy in his famous Golden Phase. Beyond its formal qualities, Lakeshore with Birches radiates profound stillness. Free from human figures or dramatic narrative.  Turns nature into a psychological sanctuary. The solitary birch trunk stands almost like a quiet observer at the edge of the water. It seems like a subtle proxy for the solitary painter himself. During his summer retreats at the Attersee, Klimt used landscape painting as a palette cleanser, freeing himself from the contentious public commissions and psychological weight of his Viennese portraiture. In Lakeshore with Birches, he captures the fleeting light and quiet isolation of late summer. He converted a humble patch of lakeside grass and water into an intricate sanctuary of pattern and color. It remains a testament to Klimt’s unique ability to merge acute observation with abstract harmony.  

  • Brain molecule may improve sleep

    ByJustpaste.in

    Millions of people around the world struggle with insomnia and other sleep problems. Now scientists in China have identified a natural brain molecule that may help explain how the body knows when it is time to sleep. The discovery could lead to safer and more effective sleep medicines in the future. The study published in Nature Neuroscience found that a natural molecule called tryptamine (TrpA) plays an important role in increasing the body’s need for sleep. Researchers say this molecule sends signals to the brain that it is time to rest. Experts explained that good sleep is essential for overall health. During sleep the brain organizes memories stores information and removes waste that builds up during the day. However many people do not get enough sleep because of insomnia stress depression anxiety or problems with the body’s internal clock also known as the circadian rhythm. To better understand the process researchers studied mice which are active at night and pigs which are active during the day. Using a special fluorescent sensor they measured the amount of tryptamine in the animals’ cerebrospinal fluid at different times. The scientists found that the longer the animals stayed awake the higher their tryptamine levels became. This suggests that the molecule reflects the body’s natural “sleep pressure” the growing need for sleep after spending many hours awake. The team also discovered that active nerve cells release tryptamine while the body is awake. The molecule then attaches to a receptor called GPR139 which activates sleep promoting nerve cells in an area of the brain known as the hypothalamic preoptic area. In the next stage of the study researchers tested experimental compounds that activated the GPR139 receptor. The results showed that the animals slept longer and experienced better quality sleep. Scientists say finding the same results in both mice and pigs suggests that this biological system may also exist in humans. If future studies confirm this the discovery could help develop new treatments for insomnia and other sleep disorders that are safer more effective and have fewer side effects than many current sleep medications.

    Marc Padeu is reimagining renaissance masterpieces

    ByJustpaste.in

    In the global art world, classical European masterpieces have long held a dominant position in defining sacred aesthetics, grand narratives, and historical gravity. However, Cameroonian visual artist Marc Padeu is challenging this historical monopoly by taking the iconic compositions of Old Masters such as Caravaggio, Diego Velázquez, and Titian. He’s transplanting them directly into the lush, everyday landscapes of rural Central Africa. Padeu’s striking large-scale canvases reimagine classic biblical motifs and European artistic traditions against the backdrop of cocoa plantations and rural villages in Cameroon. Far from being a mere imitation of Western techniques, Padeu’s work represents a deliberate re-centering of world history, spiritual heritage, and local identity. A Dual Spiritual and Cultural Inheritance Born and raised in Cameroon, Padeu grew up navigating two distinct spiritual and cultural realities. The formal structure of Catholic devotion and the indigenous customs of Bamiléké animism. This dual background permeates his paintings, where sacred rituals and everyday agricultural labor exist side by side. In Padeu’s compositions, classical Christian iconography such as the baptism of Christ, the martyrdom of saints or solemn biblical gatherings is integrated into scenes of fieldworkers harvesting cocoa pods along riverbanks. Rather than treating these scenes as contradictory, Padeu views them as a natural reflection of human experience. He points out that the original stories of the Bible were ultimately rooted in the lives of ordinary people engaging in daily, unvarnished labor. Extending the Legacy of the Old Masters When Padeu incorporates the compositions, dramatic lighting, and gestures of European Renaissance masters, his objective is not passive homage or simple satire. Instead, he describes his creative philosophy as an extension of the art historical narrative. By placing Black African figures at the center of classical visual compositions, Padeu reframes European iconographic conventions as a shared human language. His paintings suggest that spiritual gravity, dignity and monumental art belong just as naturally to a Cameroonian cocoa harvest as they do to a 16th-century Italian cathedral. The Art of Patience and Global Recognition Padeu’s meticulous process reflects a deliberate rejection of fast-paced contemporary art production: Deliberate Pace: He completes rarely more than ten paintings per year. Long Incubation: Months are spent conceptualizing each piece before a brush ever touches the canvas. Global Reach: His recent solo exhibition in London highlights his growing prominence on the international stage.   Padeu’s ultimate creative ambition is both subtle and transformative. Rather than shaping his art to explain Africa to Western audiences, his goal is to present the wider world through an African lens. His work offers a perspective rooted firmly in the soils, traditions, and realities of Cameroon.

    Jean Rhys’s “Good Morning, Midnight” whispers in the dark

    ByJustpaste.in

    When Jean Rhys published Good Morning, Midnight in 1939, it was met with a chorus of discomfort and bewilderment. Critics at the time found its tone too bleak, its protagonist too unvarnished, and its atmosphere too heavy with melancholy. Yet decades later, this tragic, brilliant novel stands out as one of the most hauntingly modern studies of isolation, vulnerability, and resilience ever written. It is a work that does not simply invite readers into a story; it pulls them directly into the fractures of a wounded mind. The novel centers on Sasha Jansen, an aging Englishwoman returning to Paris after a long absence. Having scraped together a modest sum of money, she hopes to use the trip as a desperate attempt to patch over her fraying life. But the Paris Sasha steps back into is not a romantic city of artists and cafes; it is a claustrophobic landscape of cheap, dimly lit hotel rooms, cold streets, and judgemental eyes. Traumatized by a past filled with poverty, loss, and abusive relationships, Sasha moves through the city like a ghost in her own life, attempting to dull her emotional pain with alcohol while simultaneously craving a human connection she fears will ultimately destroy her. What makes Rhys’s narrative so compelling is her incredible command of internal voice. Written in a tight, stream-of-consciousness style, the novel obliterates the boundary between Sasha’s thoughts and the world around her. Rhys captures the quiet humiliation of financial insecurity. The constant calculation of tips, the fear of being judged by hotel staff, the defensive impulse to buy cheap clothes just to look respectable. Through Sasha’s eyes, even everyday interactions carry a terrifying weight. When she encounters a young Russian man who mistakes her for someone wealthier, or when she interacts with an eccentric gigolo, the tension is palpable. The reader is trapped right alongside Sasha. They navigate the razor-thin line between her deep yearning for intimacy and her absolute terror of being hurt. Beyond its psychological depth, Good Morning, Midnight is a social critique. Published on the cusp of World War II, the novel subtly mirrors the anxiety and dislocation of late-1930s Europe. Sasha’s struggle highlights how unforgiving society can be to women who fall outside traditional expectations of youth, wealth, and domestic stability. She is a woman adrift in an urban landscape that demands self-sufficiency while offering no safety net, making her experience feel astonishingly contemporary to modern readers facing their own eras of isolation and uncertainty. Rhys’s prose is razor-sharp, sparse, and poetic, delivering emotional blows with remarkable economy. The book’s final passage remains one of the most famous, devastating, and deeply ambiguous endings in twentieth-century literature. It is neither a story of neat redemption nor one of complete surrender, but rather a quiet, defiant acceptance of life’s painful complexities. Good Morning, Midnight demands that we look directly at the aspects of human suffering we often try to ignore; loneliness, aging, and  poverty. Jean Rhys offers a masterpiece of modernism that feels as vital, raw, and resonant today as it did nearly a century ago.
