(Press-News.org) A new study led by Professor Jonghun Kam's team at POSTECH(Pohang University of Science and Technology) has uncovered a shocking forecast for Pakistan's future. Using a cutting-edge AI model, the research predicts that the country will face unprecedented "super floods" and "extreme droughts" on a periodic basis. This dire prediction is a direct result of accelerating global warming, which is causing more frequent and severe extreme weather events around the world, particularly in vulnerable high-altitude regions where glacies are melting.
The team focused on Pakistan because its major rivers, like the Indus, are the country’s lifeline, but climate change has made water resources management increasingly difficult. As a "Global South" nation, Pakistan is especially vulnerable to climate change and lacks the economic and technological infrastructure to conduct extensive research.
AI Tackles Inaccurate Climate Models
To overcome these challenges, Professor Kam's team turned to artificial intelligence. Traditional climate models often struggle with complex terrains like Pakistan's steep mountains and narrow valleys. They tend to underestimate changes in these areas or overestimate rainfall, which makes their predictions unreliable.
The researchers trained several AI models by comparing past river flow data with actual observations, which dramatically improved the accuracy of their predictions for past extreme weather events. This AI-corrected data proved to be far more reliable than existing models.
What Does the AI Forecast?
The analysis revealed a disturbing pattern. The upper Indus River could experience major floods and severe droughts approximately every 15 years. Surrounding rivers could face the same extreme events even more frequently, roughly every 11 years. This projection is a clear call to action, urging the Pakistani government to adopt tailored water management strategies for each river basin instead of relying on a one-size-fits-all approach. Professor Kam stated that this new AI technology will be crucial for producing reliable climate data not only for Pakistan but also for other climate-vulnerable and data-poor regions around the globe.
This research was conducted by the team of Professor Jonghun Kam from POSTECH's Division of Environmental Science and Engineering and doctoral student Hassan Raza, in collaboration with Professor Dagang Wang's team from Sun Yat-sen University in China. The study was published in the international academic journal Environmental Research Letters, and was supported by the National Research Foundation of Korea's Individual Basic Research Program and the BK21 FOUR Program. Hassan Raza received support from the ‘Global Korean Scholarship’.

**EMBARGOED FOR RELEASE UNTIL TUESDAY, SEPT. 2, AT 7:30 P.M.**
Researchers at the Johns Hopkins Kimmel Cancer Center, Johns Hopkins All Children’s Hospital and four other institutions have devised a novel method to test for prostate cancer using biomarkers present in urine, funded in part by the National Institutes of Health. This approach could significantly reduce the need for invasive, often painful biopsies, they say.
By analyzing urine samples from prostate cancer patients before and after prostate-removal surgery, as well as from healthy individuals, ...
Dad’s childhood passive smoking may confer lifelong poor lung health onto his kids
2025-09-02
A father’s exposure to passive smoking as a child may impair the lifelong lung function of his children, putting them at risk of COPD—a risk that is heightened further if they are childhood passive smokers themselves—finds research published online in the respiratory journal Thorax.
The findings highlight the intergenerational harms of smoking, say the researchers, who urge fathers to intercept this harmful legacy by avoiding smoking around their children.

People with learning disabilities seem to progress faster to severe type 2 diabetes
2025-09-02
People with learning disabilities progress faster to severe type 2 diabetes and are at greater risk of dying from their condition than people without these disabilities, suggests research published in the open access journal BMJ Open Diabetes Research & Control.
This is despite having better overall blood glucose control and similar risks of vascular complications, the findings indicate.
Around 1.5 million people (950,000 adults) in the UK have a learning disability, which includes conditions such as Down syndrome and cerebral palsy, note the researchers.

Researchers find Medicaid is crucial to access treatment for opioid addiction
2025-09-02
Medicaid plays a key role for giving people with opioid-use disorder access to treatment, according to a Rutgers Health study.
Progress in life-saving treatment for opioid-use disorder with the medication has stalled in the past several years, according to a Rutgers Health study. However, researchers added that while some states were able to achieve substantial improvement, others lost ground.
Specifically, states that have expanded access to Medicaid insurance coverage since 2018 saw increases in prescriptions for opioid-use disorder treatment, according to the study, while states that haven’t ...
New research shows changing winters will hit northern lakes the hardest
2025-09-02
Duluth, MN - In the world’s cold and snowy regions, shorter and warmer winters are one of the most conspicuous consequences of climate change. For freshwater lakes, this means later freezing, earlier thawing, and thinner ice. A new study, published in Ecology Letters, shows that the ecological impacts of these winter changes may be most dramatic in high-latitude lakes.
“The ecology of ice-covered lakes is a bit of a black box for lake scientists,” said Ted Ozersky, a University of Minnesota Duluth biologist who led the research. “For a long time, we assumed that nothing interesting happened under the ice, so few studies looked at what goes on in ...
Wildfire ‘char’ may help suppress methane
2025-09-02
It's hard to believe that there is anything positive that could come out of wildfires. They have devastated homes, taken lives, erased memories, leveled cities and destroyed our forests and wildlands. But a University of Delaware professor has found that there is something of value to be learned from what’s left behind in the remnants.
The charred debris left in the wake of wildfires, such as those currently burning in Colorado, Canada and Arizona’s Grand Canyon National Park, is known as wildfire char. UD’s Pei Chiu, professor of civil, construction ...

Heart rate is one of the most basic and important indicators of health, providing a snapshot into a person’s physical activity, stress and anxiety, hydration level, and more.
Traditionally, measuring heart rate requires some sort of wearable device, whether that be a smart watch or hospital-grade machinery. But new research from engineers at the University of California, Santa Cruz, shows how the signal from a household WiFi device can be used for this crucial health monitoring with state-of-the-art accuracy—without the need ...
Despite relaxed prescribing rules, opioid addiction treatment still hard to find at pharmacies
2025-09-02
Faced with a worsening drug crisis, policymakers in recent years have made it much easier for doctors to prescribe the highly effective opioid addiction treatment buprenorphine. However, many patients may still struggle to find pharmacies carrying the treatment, finds new research led by the USC Schaeffer Center for Health Policy & Economics.
Buprenorphine was available at just 39% of U.S. retail pharmacies in 2023, a modest increase from 33% in 2017, according to the study published Sept. 2 in Health Affairs. But disparities in who can access the treatment have persisted. Pharmacies in predominantly Black neighborhoods (18%) and ...
