Researchers have unveiled an innovative AI tool that can pinpoint recent locations by examining microorganisms collected from a person’s body. Published in Genome Biology and Evolution, the study shows that each environment hosts unique microbial communities, which act like "microscopic fingerprints" with distinct geographical signatures.
By analyzing these microbes, the tool can determine if someone has recently visited places like beaches, train stations, or parks.
Developed at Lund University in Sweden, this tool—unlike traditional GPS—relies on the Microbiome Geographic Population Structure (mGPS) model. It leverages AI to examine microorganisms such as bacteria, fungi, and algae, which differ by location and leave clues about where a person has been.
According to researcher Eran Elhaik, “By tracing where your microorganisms have been, we can track disease spread, identify infection sources, and even aid criminal investigations.”
To train the AI, scientists gathered extensive microbiome data from diverse environments, including urban and soil samples across 18 countries and marine samples from nine water bodies.
Remarkably, the mGPS tool accurately identified the city source for 92% of urban samples. It even distinguished samples from two Hong Kong subway stations only 564 feet apart, though accuracy was lower in London, potentially due to the Underground’s less maintained stations.
This advancement opens doors to applications in medicine, epidemiology, and forensics, with accuracy expected to improve as more data is gathered.

Elon Musk’s AI Chatbot ‘Grok’ Ignites Healthcare Innovation Debate
Elon Musk’s AI chatbot, Grok, is sparking widespread discussion in healthcare as users on X (formerly Twitter) experiment with its ability to analyze medical images like X-rays, MRIs, and CT scans. Musk has championed Grok’s potential in diagnosing diseases, emphasizing its promising early results and his plans to enhance its accuracy through user data. However, this approach has raised serious concerns about privacy, data security, and ethics.
Grok has been tested on conditions such as brain tumors and bone fractures, with mixed feedback. While some users praised its ability to identify tumors, others reported errors, like confusing a broken bone for a dislocation. Experts argue these inconsistencies highlight the challenges of adapting general AI systems for medical use.
Privacy concerns loom large. Unlike regulated healthcare providers, X isn’t subject to stringent laws like HIPAA. Although the platform claims not to sell user data, its policy of sharing data with related entities has raised alarms about how sensitive medical information might be handled.
While AI holds transformative potential for healthcare, experts stress the importance of thorough testing and user education. Sharing sensitive medical data with non-regulated platforms demands careful consideration to balance innovation with safety and privacy.
ASEF Executive Committee Meeting Held in Singapore
The Executive Committee Meeting of the Asia-Europe Foundation (ASEF) concluded in Singapore on 22 November 2024 with a renewed commitment to further collaboration between the countries from the two continents, Asia and Europe.
The Director-General, Regional Organizations of the Ministry of Foreign Affairs, Md. Rais Hasan Sarower, NDC, as the current chair of the ASEF Board of Governors, led the discussion.
In addition to discussions on a wide range of administrative and financial matters, the executive body also provided directives to enhance the visibility of the organization and recommended exploring new funding mechanisms and ensuring data privacy and strategic upgrades to make ASEF more meaningful for member states.
The meeting also approved a project proposal for women, peace, and security training proposed by the Government of Latvia.
To complement the ASEM process, in February 1997, the 1st ASEM Foreign Ministers' Meeting welcomed the establishment of the Asia-Europe Foundation (ASEF). Based in Singapore, ASEF provides opportunities for Asians and Europeans to exchange ideas and collaborate, and achieve innovative and substantive solutions for common global challenges.
Bangladesh has been the Chair of the ASEF Board of Governors for the first time since January 2024 and the term will end in December 2024.

John Alfred Tinniswood, World’s Oldest Man, Dies at 112
John Alfred Tinniswood, celebrated as the world’s oldest man, passed away peacefully at the age of 112 on Monday in a Southport care home. A devoted Liverpool FC supporter, Mr. Tinniswood gained the title of the world’s oldest man in April 2024, following the death of Juan Vicente Pérez Mora.
Born on August 26, 1912—the year the Titanic sank—Mr. Tinniswood was acknowledged as the UK’s oldest man in 2020 and earned global recognition this year from the Guinness Book of Records.
A widower, he is survived by his daughter Susan, grandchildren Annouchka, Marisa, Toby, and Rupert, and great-grandchildren Tabitha, Callum, and Nieve. His family remembered him as wise, courageous, and eloquent, traits he displayed during his service in World War II with the Royal Army Pay Corps, where he oversaw logistics and accounts.
In 1942, he married his wife Blodwen, with whom he shared 44 cherished years until her death in 1986. After the war, Mr. Tinniswood pursued a career with Royal Mail and later as an accountant for Shell and BP, retiring in 1972. He remained active in retirement, serving as a church elder and delivering sermons at Blundellsands United Reform Church. His family shared that he passed “surrounded by music and love.”

Dengue Claims 47 Lives in A Week
The dengue outbreak in the country is not decreasing in any way. Along with the deaths, the number of infected people is also increasing. The pressure of patients in hospitals increasing.
According to the dengue report of the Department of Health, 47 have died of dengue this week (November 23 to November 29) and 5,968 have been admitted to hospitals.
According to the statistics of the last seven days,
November 23: 10 died, 886 hospitalized
November 24: 11 died, 1,079 hospitalized
November 25: 2 died, 934 hospitalized
November 26: 10 died, 990 hospitalized
November 27: 4 died, 888 hospitalized
November 28: 7 died, 837 hospitalized
November 29: 3 died, 354 hospitalized.
So far this year, 90,793 people have been hospitalized due to dengue. Of these, 87,281 have been discharged. 485 died.
Atiqur Rahman, a specialized doctor at DMCH said that dengue is no longer seasonal, it occurs throughout the year. It increases when it starts raining. In addition to using mosquito repellents to prevent dengue, the city corporation must also conduct campaigns everywhere. At the same time, everyone must be aware of it.
Entomologist Dr Manjur Chowdhury says that not only public awareness will work to control mosquitoes. Appropriate measures must be taken by conducting proper surveys and using skilled manpower.
It is worth noting that in 2023, the highest number of dengue patients in the country's history was 3,21,179, and 1,705 people died.
