The Riyadh Metro, overseen by the Royal Commission for Riyadh City (RCRC), officially welcomed its 100 millionth passenger, less than nine months after the launch of the network in early December 2024.

Riyadh Metro’s Blue Line, which runs along the Olaya-Batha axis, has seen the highest ridership, with around 46.5 million passengers to date. The Red Line along King Abdullah Road follows with 17 million riders, while the Orange Line on Al Madinah Al Munawwarah road recorded 12 million. The remaining three lines have collectively served around 24.5 million passengers.

Since operations began, the metro has maintained a 99.78% on-time performance rate, the Saudi Press Agency reported on Tuedsay.

Some of the network’s busiest stations included Qasr Al Hokm, KAFD, stc, and the National Museum interchange stations, collectively accounting for over 29% of total ridership.

The Riyadh Metro is seamlessly integrated with an extensive bus network, including on-demand bus services and public transport parking facilities, offering a smooth and accessible journey for commuters from the moment they leave their homes to their final destinations.

The integrated system enhances mobility within the capital and provides diverse options for both residents and visitors alike, further reinforcing the role of public transport as a modern, urban, and sustainable choice.

Swimmers will for the second year be able to cool off at designated points along the Seine River in Paris this summer, authorities said Friday, as well as along the Marne River in the suburbs.

In Paris, the swimming season was to open at three official bathing sites on July 4, the mayor's office said.

The Seine reopened to swimmers last summer for the first time in a century, after Paris poured more than a billion euros ($1.15 billion) into a years-long effort to making the waters clean enough to use in the 2024 Olympics.

Sites this year will again include the Bras de Grenelle near the Eiffel Tower, the Bras Marie -- a short walk from Notre-Dame -- and Bercy, on the eastern side.

Some 100,000 people last year queued to jump in, the city said, despite a slow start to the season with rain disrupting the water quality.

Some 50,000 swimmers jumped into the Marne River in the eastern suburbs last year.

The bathing spots in Joinville-le-Pont, Champigny-sur-Marne, Saint-Maur-des-Fosses and Maison-Alfort would again welcome swimmers. A fifth spot would be added this year at Neuilly-sur-Marne northeast of Paris.

French authorities warned against swimming in parts of the rivers without lifeguards.

An independent researcher has uncovered potential blunder in scores of scientific studies, including cancer-related research, as a result of inappropriate antibody use in laboratory experiments, raising questions about the reliability of some of the results published in prestigious scientific journals.

The researcher found that scientists at Cambridge, Oxford, Stanford and other universities appear to have accidentally used the wrong ingredient in their experiments, muddling two proteins with similar names but entirely different sequences and functions.

Several British media outlets said researcher Sholto David reviewed the full text of 334 research papers to determine whether the antibody used in the studies was correctly intended for p16-ARC or incorrectly used to try and bind p16-INK4a.

P16-INK4a acts as a tumor suppressor by halting the cell cycle and is widely studied in cancer biology and is considered a key biomarker of ageing.

He found astonishing result: 95% of these papers have got it wrong.

“The vast majority of researchers who purchased antibodies have tried to use them to investigate p16-INK4a expression. Only 17 used these p16-ARC antibodies correctly,” he said in his research.

David said the implications are not good, to put it mildly.

“And these are not just insignificant papers. There are papers with hundreds of citations in high impact journals claiming to probe for p16-INK4a with antibodies which do not bind p16-INK4a,” he noted.

A highly active volcano in eastern Indonesia erupted several times on Friday, spewing towering ash columns into the sky and forcing a local airport to close, authorities said.

Mount Lewotobi Laki-Laki on Flores Island erupted at 11:15 am (0315 GMT), sending volcanic material 2.5 kilometers (1.6 miles) into the air, the national volcanology agency said in a statement.

It came after several other eruptions earlier on Friday.

Lewotobi Laki-Laki falls under Indonesia's second-highest alert level for volcanic activity, with a five-kilometer exclusion zone in force around its crater.

The volcanology agency said residents near rivers should also remain on alert for hazardous floods of volcanic material, known as lahar, if heavy rain occurs.

Authorities have suspended operations at a local airport in the town of Maumere, about 60 kilometers west of Lewotobi Laki-Laki, affecting five domestic flights, airport head Partahian Panjaitan told AFP.

Laki-Laki means "man" in Indonesian, and the 1,584-meter (5,197-foot) volcano is twinned with a calmer 1,703-meter one named Perempuan after the Indonesian word for "woman".

Last July, Lewotobi Laki-Laki spewed a colossal 18-kilometer tower of ash, forcing the cancellation of 24 flights at the international airport on the resort island of Bali.

Indonesia, a vast archipelago nation, experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire".
