This Ancient Spice May Hold The Key to Tomorrow’s Antivirals – Asian Scientist Magazine

AsianScientist (Nov. 26, 2025) –Long celebrated for its aroma and flavour, cardamom might soon spice up the world of medicine too. Scientists from Japan’s Shinshu University have discovered that cardamom seed extract can trigger the body’s antiviral defenses at a cellular level. Their findings reveal that cardamom seed extract and its main bioactive compound, 1,8-cineole, stimulate the production of antiviral molecules known as type I interferons via nucleic acid ‘sensors’ inside cells, that hel...

Scientists Grow Ureter Tissue, Edge Closer To Lab-Made Kidneys – Asian Scientist Magazine

AsianScientist (Sep. 29, 2025) – Chronic kidney disease is a global public health problem, affecting about 10 percent of the world’s population. Today, an estimated 2.6 million patients rely on renal replacement therapy, through dialysis or kidney transplantation – a number projected to double by 2030.
To meet this growing need, scientists have turned to regenerative medicine. But building fully functional kidneys in the lab has remained elusive, largely because one crucial part of the urinary s...

Late-Night Dinners And Skipped Breakfasts Linked To Weaker Bones – Asian Scientist Magazine

AsianScientist (Sep. 27, 2025) – Osteoporosis, a skeletal disorder marked by weakened bones and a higher risk of fracture, is typically associated with aging, hormonal changes, and lifestyle factors such as exercise, alcohol consumption and smoking. However, much less is understood about how dietary habits contribute to the risk of osteoporotic fractures.
Now, new research from Japan suggests that everyday eating patterns, such as skipping breakfast or eating late at night, could also raise the...

Fragmented forests and food scarcity threaten capped langurs

The capped langur (Trachypithecus pileatus), a leaf eating primate with a distinctive ‘cap-like’ hairstyle, is the second most commonly seen primate in Assam after the rhesus macaque. Once thriving in the tropical rainforests of the Upper Brahmaputra Valley, the only colobine primate (characterised by their leaf-based diet) in the region, is now in a precarious situation.

The Valley was once covered by a vast lowland tropical rainforest. However, over the years, agricultural expansion, deforest...

Scarred But Unseen: How Childhood Neglect Rewires The Brain – Asian Scientist Magazine

AsianScientist (Sep. 24, 2025) – Affecting three out of four children in substantiated abuse cases worldwide, child neglect occurs when caregivers fail to provide a child with basic necessities such as food, shelter, supervision, or protection. While less visible than physical abuse, neglect can leave deep and lasting imprints on a child’s development, many of which have only recently begun to be scientifically understood.
Child neglect has been linked to impaired social and emotional skills, an...

The hills have AIs

Ever since Tenzee Lhawang Bhutia started a backpackers’ hostel in the heart of Darjeeling three years ago, he has been bombarded with the usual questions by travellers –– where to eat, what to see, where are the hidden spots. Tired of repeating himself, Tenzee decided to build a smart solution instead: Ask Darj, a hyperlocal, AI-powered WhatsApp chatbot designed to act as “a local in your pocket.” “We wanted the chatbot to feel like a local guiding you through the old city. The idea is that when...

Low Blood Sugar Before Pregnancy May Raise Birth Complications – Asian Scientist Magazine

AsianScientist (Sep. 10, 2025) – Blood sugar levels are usually associated with diabetes, but new research shows they can also play a crucial role in pregnancy outcomes. A large-scale study from China has found that women with low blood sugar levels before pregnancy may face a higher risk of complications such as preterm birth and low birth weight.
Glucose, a type of sugar and the body’s primary source of energy, plays a vital role in maintaining health. Both high blood sugar (hyperglycemia), co...

Conflicted over attacks on mithuns, experts gun for hunting ban

Early this year, when 40-year-old Taum Tamut went looking for his mithuns (Bos frontalis) in the forest surrounding his village Jomlo Mobuk in Siang district of Arunachal Pradesh, he came across a grim sight. One of his mithuns lay dead, its carcass bearing the unmistakable marks of a dhole (Cuon alpinus) attack.

Taum, a member of the Adi tribe and a father of three young children, has around 50 mithuns and earns his livelihood by selling vegetables, broomsticks, and occasionally a mithun or tw...

Regular Opioid Use May Lead To Cognitive Decline – Asian Scientist Magazine

Japanese Macaques May Mourn Their Loved Ones Like Humans – Asian Scientist Magazine

AsianScientist (Aug. 01, 2025) – The ability to grieve for dying loved ones was long considered a distinctly human trait — an emotional complexity thought to separate us from animals. But new research from Japan is challenging that view.
In a study published in Primates, researchers from The University of Osaka have found that Japanese macaques display remarkably human-like responses to the deaths of their adult companions, offering fresh insights into the emotional lives of non-human primates....

Churpi from mithun milk could boost farmer incomes

Churpi, a variety of hardened cheese, is a popular traditional snack in the Himalayan belt of Nepal, Bhutan, Tibet and parts of northeastern India. Primarily made from yak milk, it can also be made using cow or buffalo milk, and even the milk of chauris, a crossbreed of yak and cow. Arunachal Pradesh is known for its Geographical Indication (GI) tagged churpi made from yak milk.

Recently, a farmer from the Adi tribe of Arunachal Pradesh has developed churpi made from the milk of mithun — a semi...

Faraway Festival of Eclectic Esoterica

The road leading to the land of the Lisu tribe in Arunachal Pradesh is long and arduous. If one travels by road from Guwahati in Assam, it takes an overnight bus or train ride to Tinsukia, followed by a three-hour drive to Miao. From there a backbreaking nine-hour journey on a 4x4 pickup truck, through the dense forests of Namdapha National Park finally leads to Gandhigram, a remote village nestled in the easternmost corner of Arunachal Pradesh, bordering Myanmar. Also known as the Yobins, the L...

Oceans Hold Key To Forecasting China’s Prolonged Summer Rains – Asian Scientist Magazine

AsianScientist (May. 19, 2025) – Extreme rainfall events in China, from flash floods to devastating landslides, often leave a trail of destruction. While their frequency and intensity have been studied extensively, one crucial element has remained elusive: duration. How long it rains can be just as critical as how hard it rains. Now, a team of climate scientists may have found the key to predicting such prolonged rainfall — hidden in the oceans.
A new study published in Advances in Atmospheric S...

Heart Research Has A Gender Bias – Asian Scientist Magazine

AsianScientist (May. 09, 2025) – One afternoon in 2022, when 60-year-old Lekshmi could no longer bear the chest pain she had been brushing off as gastritis for the past few weeks, she rode her scooter to a private hospital near her home in Alleppey, a city in southern India. The doctors at the hospital ran a few tests and advised her to get admitted for checkups. But Lekshmi declined. She told the doctors that she lived alone and would prefer to come back when her daughters, who lived outside Al...

Antibiotic Resistant Bug Found in Retail Chicken In Bangladesh – Asian Scientist Magazine

Ancient Earth Had Green Oceans – Asian Scientist Magazine

AsianScientist (Apr. 09, 2025) – When Voyager 1 spacecraft captured a photo of the Earth from six billion kilometres away, astronomer Carl Sagan famously described our planet as a “pale blue dot.” That blue hue was sunlight scattering and reflecting off of the oceans. But now, researchers in Japan have found evidence that Earth’s oceans may not have always been blue — they were green.
A group led by Taro Matsuo from Nagoya University in Japan, has found evidence that cyanobacteria, often called...

The Birdman of Nagpur

Tewani, who lives with his wife, found himself looking for a fulfilling way to spend his days after his retirement from the Bank of India in January 2012. Two years later, while flipping through Twinkle Star, a children’s magazine published in Nagpur, he came across an article about the declining population of sparrows in the city. “I thought, why not help them myself?” says Tewani. He first started building birdhouses with materials he could find locally. This repurposing of scrap helped him ke...
