Scientists Determine Neurons that Remove 'Unnecessary' Memories

During sleep, certain neurons work on removing unnecessary information from the brain. In their study published in the Science journal, researchers from Japan and the US said that while sleeping, the human brain processes the information and events that took place during the day.

Researchers led by Shuntaro Izawa from Japan's Nagoya University, said the brain store or remove the information based on its level of importance, reported the German News Agency.

According to scientists, forgetting is an active process in the brain. The researchers said they know nothing about the neural processes behind forgetting or remembering, or about the sleep stage during which the information sorting and removal takes place.

Humans go through two sleep stages: the rapid eye movement sleep (REM) and the non-rapid eye movement (NREM); the first starts about 90 minutes after drowsiness, and features excessive eye movement, muscles relaxation, and increased heart rate.

The rapid eye movement sleep (REM) is also known as the dreaming stage, during which the sleeper dreams actively. In previous studies, scientists suggested that the human brain removes some memories during the rapid eye movement sleep stage (REM).

In the new study, the researchers examined the role of the so-called MCH cells in the hippocampus, a peanut-size region found in the bottom of the brain. These findings may explain why people forget their dreams quickly, "since the dreams mostly take place in the REM stage, during which the MCH cells are highly active."

They also suggested that this high activity may be inhibiting the storage of dreams in the hippocampus, which makes people forget their dreams swiftly," said Neuroscientist Thomas Kilduff.

The National Center for Wildlife (NCW) announced that the total number of wildlife animals released under its breeding and reintroduction programs for locally threatened species has exceeded 10,000 animals, an achievement reflecting the scale of the center’s sustained efforts to develop wildlife, restore ecosystems, and enhance biodiversity across various regions of the Kingdom.

The releases carried out by the center over the past years included more than 80 priority wildlife species, including reem gazelles (sand gazelles), Arabian oryx, Idmi gazelles, mountain ibex, houbara bustards, ostriches, and sandgrouse, as part of efforts aimed at supporting the recovery of natural populations of these species and enhancing their sustainability within their environmental and historical ranges, SPA reported.

CEO of NCW Dr. Mohammad Qurban noted that release operations are among the key tools for restoring ecosystems and reducing ecological imbalance, as the return of wildlife to their natural habitats contributes to protecting biodiversity and improving environmental quality, which in turn supports habitat integrity, the continuity of plant and animal components, and the enhancement of ecosystem functions over the long term.

NCW continues to implement its strategic plans to develop wildlife, protect endangered species, and enhance the efficiency of natural habitat management through expanding breeding programs, enhancing applied scientific research, building national capacities, and applying the best international practices in biodiversity management, in addition to raising environmental awareness, engaging local communities, and supporting eco-tourism, thereby contributing to achieving the objectives of the Saudi Green Initiative and Saudi Vision 2030, and the National Environment Strategy, toward thriving and sustainable wildlife, biodiversity, and ecosystems.


Somalia Welcomes Its First Bowling Alley as the Middle Class and Diaspora Returnees Grow

Somalia Welcomes Its First Bowling Alley as the Middle Class and Diaspora Returnees Grow

In a city long defined by conflict, Somalia ’s capital of Mogadishu now echoes with the crash of pins at the country's first modern bowling alley.

It's the latest sign of revival in the once-thriving Indian Ocean port shaped by 35 years of civil war and militant bombings. Millions of people were forced to flee what became one of the world’s most dangerous cities. Those who remained avoided public spaces as the al-Qaeda-linked group al-Shabab waged an insurgency against the Somali state.

In recent years, improved security measures against al-Shabab, an expanded government presence and growing private investment have allowed daily life to re-emerge. Cafes line newly reopened streets, beaches draw evening crowds and traffic congestion, once unimaginable, now clogs key intersections.

The Feynuus Bowling Center opened last year and draws many locals and Somalis returning from the diaspora, who bring investment and business ideas after years of sending billions of dollars in remittances from abroad.

On a recent evening, young Somalis gathered in groups, laughing and filming each other on their phones while music played. Many from the diaspora are visiting Mogadishu for the first time in years, or the first time ever.

“I couldn’t believe Mogadishu has this place,” said Hudoon Abdi, a Somali-Canadian on holiday, as she prepared to take her turn to bowl.

“I’m enjoying it. Mogadishu is actually safe,” she said, urging others to visit.

Mogadishu remains vulnerable to militant attacks, however, with security measures like checkpoints and heavily guarded zones part of daily life. Non-Somalis remain largely confined to a compound at the international airport.

But residents say the ability to gather for recreation signals an important psychological shift. Such venues provide a welcoming environment for a younger generation eager for safe spaces to socialize.

Abukar Hajji returned from the United Kingdom on holiday after many years away and found the difference between what he imagined and what he experienced eye-opening.

“When I was flying from the UK, I believed it was a scary place, like a war-torn country,” he said. “Everyone told me, ‘Good luck,’ but when I came and saw it with my own eyes, I didn’t want to leave.”

Sadaq Abdurahman, the manager of the bowling center, said the idea for the business emerged from a growing demand among young people for recreational facilities.

“It has created employment opportunities for at least 40 youths,” he said.

According to the Somali National Bureau of Statistics, Somalia’s unemployment rate stands at 21.4%.

The bowling alley has private security guards, bag checks and surveillance cameras, reflecting the precautions common at public venues in Mogadishu.

Urban planners and economists say businesses like the bowling alley signal a broader shift in Mogadishu’s recovery, as private sector growth increasingly complements international aid and government-led rebuilding efforts.

Ahmed Khadar Abdi Jama, a lecturer in economics at the University of Somalia, said innovative businesses are responding to the needs of diaspora returnees and the growing middle class, “which in turn adds to the expected increase in Somalia’s GDP.”

Outside the bowling alley, traffic hummed and neon signs flickered, other reminders of Mogadishu’s fragile transformation.
