A pill that vibrates to relieve constipation, a sensor that can be tracked in the gut -- medical researchers are turning to tiny robots to treat or diagnose gastrointestinal disorders.

"This is a very booming field," said Saransh Sharma, a doctoral student at the California Institute of Technology (Caltech) involved in the development of the ingestible diagnostic sensor.

"You have medical robots that are so small you can just send them inside a person using the oral passage and they can do a lot of sensing and actuation inside the gut," Sharma told AFP.

About 16 of every 100 adults in the United States suffer from symptoms of constipation, according to the US health authorities, and the number doubles for Americans over the age of 60.

Researchers at the Massachusetts Institute of Technology (MIT) and Caltech have developed an ingestible sensor that can be monitored as it travels through the digestive tract.

The device, 20 millimeters in length and eight mm in diameter, could help physicians diagnose gastrointestinal motility disorders that prevent food from moving normally through the digestive tract.

The capsule's location reveals where a slowdown is taking place.

"That gives the doctor a lot of the essential information to do a better job in the curing and the diagnosis and the treatment plan," Sharma said.

The sensor could also provide an alternative to invasive procedures such as endoscopy or other diagnostic techniques such as nuclear imaging, X-rays or catheters.

It has been tested on pigs and the team behind the research hopes to eventually obtain the approval of the US Food and Drug Administration for human clinical trials.

"If we can demonstrate a device inside large animals like pigs up to a very high confidence, we can say that it will scale very well in human anatomy as well," Sharma said.

The authors published the results of their research on Monday in the journal Nature Electronics.

They said the sensor works by detecting a magnetic field produced by an electromagnetic coil located outside of the body.

The strength of the magnetic field varies with distance from the coil and the sensor's position within the digestive tract can be calculated to within millimeters based on measurement of the magnetic field.

- Vibrating capsule -
While the ingestible sensor is still in the development phase, an Israeli company called Vibrant Gastro recently began marketing a vibrating capsule in the United States designed to relieve chronic constipation.

The drug-free Vibrant capsule is intended for constipation sufferers who have not received bowel relief after a month of laxative treatments. It has been FDA-approved.

In a Phase 3 clinical trial of 300 people, participants who took Vibrant had bowel movements significantly more frequently than those who took a placebo.

The Vibrant capsule produces gentle vibrations to stimulate the colon and increases the number and frequency of bowel movements, according to the manufacturer.

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.

Benefit of Taking Magnesium Does Not Get Enough Attention

Nutrition experts revealed that magnesium is often not given the same attention as other vitamins and minerals, although it plays a pivotal role in supporting the overall health of our body, especially improving blood sugar management and supporting neuro-psychological balance.

According to the US National Institutes of Health (NIH), magnesium is an abundant mineral in our body and it’s naturally present in many foods.

The mineral is required in more than 300 different reactions in our body, including those that regulate muscle and nerve function, blood sugar levels, and blood pressure.

“Magnesium plays a role in how our body handles sugar,” Scott Keatley, RD, co-owner of Keatley Medical Nutrition Therapy told Prevention magazine.

“It helps with the action of insulin, the hormone that controls blood sugar levels.” When you have enough magnesium in your body, insulin can work better and your body can manage blood sugar more effectively, Keatley said.

Also, stress can cause our body to use more magnesium than usual, which can limit our body’s ability to do other tasks with the nutrient, Keatley said.

“In addition, magnesium can help reduce the release of stress hormones like cortisol,” he said. “It’s like a natural chill pill that can help keep our body’s stress response in check.”

Magnesium helps regulate brain function and mood. It plays a role in releasing and using neurotransmitters, which are chemicals in our brain that affect our mood and emotions.

The mineral may help improve bone density and decrease fracture risk.
“Magnesium is stored in bones and is an important part of bone health,” said Deborah Cohen, DCN, an associate professor in the department of clinical and preventive nutrition sciences at Rutgers University School of Health Professions.

At baseline, magnesium can help to relax and widen your blood vessels, Keatley said. “This makes it easier for blood to flow and can help lower blood pressure,” he added. “It’s like making the highways wider so that traffic can move more smoothly.”

A 2025 review in hypertension found that magnesium seems to be beneficial for lowering blood pressure in people with high blood pressure and magnesium deficiency, but larger studies are needed.

There are a lot of foods that are high in magnesium. Nutrition experts recommended trying to get more of the nutrient in our diet from food first.

These are the most magnesium-rich foods, according to the NIH are: Pumpkin seeds, Chia seeds, almonds, spinach, cashews, peanuts, shredded wheat, soymilk, black beans, edamame, peanut butter, potato with skin, brown rice and plain yogurt.

Elon Musk said on Sunday that SpaceX has shifted its focus to building a "self-growing city" on the moon, which could be achieved in less than 10 years.

SpaceX still intends to start on Musk's long-held ambition of a city on Mars within five to seven years, he wrote on his X social media platform, "but the overriding priority is securing the future of civilization and the Moon is faster."

Musk's comments echo a Wall Street Journal report on Friday, stating that SpaceX has told investors it would prioritize going to the moon and attempt a trip to Mars ⁠at a later time, targeting March 2027 for an uncrewed lunar landing.

As recently as last year, Musk said that he aimed to send an uncrewed mission to Mars by the end of 2026.

The US faces intense competition from China in the race to return humans to the moon this decade. Humans have not visited the lunar surface since the Apollo 17 mission in 1972. Less than a week ago, Musk announced that SpaceX ⁠acquired the artificial intelligence company he also leads, xAI, in a deal that values the rocket and satellite company at $1 trillion and the artificial intelligence outfit at $250 billion.

Proponents of the move view it as a way for SpaceX to bolster its plans for space-based data centers, which Musk sees as more energy efficient than terrestrial facilities as the demand for compute power soars with AI development.

SpaceX is hoping a public offering later this year could raise as much as $50 billion, which could make it the largest public offering in history.

On Monday, Musk said in response to a user on X that NASA will constitute less than 5% of SpaceX's revenue this year. SpaceX is ⁠a core contractor in NASA's Artemis moon program with a $4 billion contract to land astronauts on the lunar surface using Starship.

"Vast majority of SpaceX revenue is the commercial Starlink system," Musk added.

Earlier on Sunday, Musk shared the company's first Super Bowl ad, promoting its Starlink Wi-Fi service.

Even as Musk reorients SpaceX, he is also pushing his publicly traded company, Tesla, in a new direction.

After virtually building the global electric vehicles market, Tesla is now planning to spend $20 billion this year as part of an effort to pivot to autonomous driving and robots.

To speed up the shift, Musk said last month Tesla is ending production of two car models at its California factory to make room for manufacturing its Optimus humanoid robots.
