AI-powered flash flood alert mini-program launched in SW China province
It employs high-precision rainfall forecasting models to provide dynamic short-term predictions covering the past hour and the following two hours, significantly improving forecast accuracy ahead of the flood season from late July to early August, according to the report. The mini-program generates 24-hour, 12-hour and 2-hour risk maps, delivering warnings via SMS, WeChat and the emergency response systems.
"People can check live monitoring footage, rainfall data, forecasts and hazard warnings to make informed evacuation decisions," said Ouyang Chaojun, an IMHE researcher. "They can also upload photos of emerging risks to help local governments evaluate the risks and respond," Ouyang added. Powered by efficient algorithms and the National Supercomputing Center in Chengdu, the system significantly improves the accuracy of rainfall predictions and the efficiency of disaster simulations in mountainous areas. Since its trial launch in May in the city of Mianyang, where it monitors all 676 ravines, the system has issued 2,034 warnings, successfully forecasting debris flows and flash floods.

AI-powered model to predict liver cancer recurrence
SINGAPORE, July 22, (Xinhua): Singaporean researchers have developed an artificial intelligence-powered scoring system capable of predicting the recurrence of liver cancer, according to a press release from the Agency for Science, Technology and Research on Monday. Developed by scientists from the Institute of Molecular and Cell Biology (IMCB) under the agency in collaboration with the Singapore General Hospital, the system can forecast the recurrence of hepatocellular carcinoma, the most common type of liver cancer, with approximately 82 percent accuracy. The system works by analyzing the spatial distribution of natural killer immune cells and five key genes within liver tumor tissues. "In Singapore, up to 70 percent of liver cancer patients experience recurrence within five years," said Principal Investigator Joe Yeong from the IMCB, noting that this system empowers clinicians to intervene as early as possible. Researchers validated the system using tissue samples from 231 patients across five hospitals. It is now accessible via a free web portal for research purposes, with plans underway to integrate it into standard clinical workflows.

Indonesia on alert as forest fires escalate in western region
JAKARTA, July 22, (Xinhua): Indonesian authorities announced that the country's western region is currently on high alert for forest and land fires, with Riau province reporting the highest number of hotspots. Indonesia's National Disaster Management Agency (BNPB) said Monday that forest and land fires have been the dominant type of disaster in the Southeast Asian country since early July. Of the 42 disasters recorded so far this month, 33 are forest and land fires. The fires have spread extensively across Sumatra Island, affecting provinces including Aceh, North Sumatra, Riau, West Sumatra, Jambi, and South Sumatra. In Riau, the most vulnerable and currently burning regencies are Kampar, Siak, Bengkalis, and Rokan Hilir, where more than 100 hectares of land have been scorched. "The hot and dry weather conditions have increased the risk, especially as rainfall has significantly declined across much of Sumatra," said Abdul Muhari, head of the center for data, information, and disaster communication at BNPB, in Jakarta. Hotspots have also been detected in Central Kalimantan, while fires have been reported at final waste disposal sites in Central Java and East Java. Separately, the Meteorology, Climatology, and Geophysics Agency office in Riau's Pekanbaru city reported that smoke from forest fires in the province has drifted into neighboring Malaysia. Satellite monitoring shows the smoke crossing the Malacca Strait and reaching parts of the Malay Peninsula. The agency warned that the number of hotspots could continue to rise if the dry conditions persist and the public fails to comply with the ban on land burning.
