Grain-sized soft robot delivers multiple medications, guided by magnetic fields

Posted by in categories: biotech/medical, food, robotics/AI

If you’re ever faced with trying to pick up a grain of rice with a pair of chopsticks, spare a thought for the scientists behind this latest innovation, which has been called “a medical breakthrough on the verge of happening.” They’ve painstakingly built a soft robot with the capacity to carry different types of drugs through the body. It’s the size of a grain of rice, and can be driven to various internal targets via magnetic fields.

Researchers in the School of Mechanical and Aerospace Engineering (MAE) at Nanyang Technological University, Singapore (NTU Singapore), have built on earlier work to create a grain-sized soft robot that can enter the body and be controlled by magnetic fields to travel to a specific target. Once there, it can quickly or slowly release the medication it has stored in its tiny frame.

Tech Millionaire Bryan Johnson Reveals How He Reversed His Hair Loss, Shares Tactics

Posted by in categories: biotech/medical, genetics

In the consequent tweets, the biohacker attributed his successful hair regeneration to a multi-faceted approach. The key to his transformation has been the strategic use of vitamins and nutrients, particularly protein and Omega-3 fatty acids, which have played a crucial role in restoring his hair.

In addition to nutrition, he has developed a personalised topical formula tailored to his genetics, that includes melatonin, caffeine, and Vitamin D3. He has also incorporated red light therapy into his daily routine, even wearing a specialised hat to administer this treatment throughout the day.

Another critical component of Johnson’s regimen is oral minoxidil, a topical hair-loss drug. However, he stressed that it is only considered safe at low doses as it can lead to unpleasant side effects, including excessive hair growth and headaches.

Crew-8 splashes down on SpaceX Dragon Endeavour after weather delays

Posted by in category: space travel

They finally came back 💙


Crew-8 astronauts Matthew Dominick, Michael Barratt and Jeanette Epps all with NASA and Roscosmos cosmonaut Alexander Grebenkin splashed down in the Gulf of Mexico off the coast of Pensacola, Florida on Friday (Oct. 25) at 3:29 a.m. EDT (0729 GMT). Their landing after 235 days — including a more than two-week wait on board the International Space Station (ISS) for acceptable conditions — set a record for their spacecraft.

Not Toyota, not Hyundai: This brand unveils the real hydrogen engine with an unexpected detail

Posted by in categories: engineering, sustainability, transportation

In a bold move towards sustainability in the automotive industry, Alpine has introduced its new V6 hydrogen engine. The engine is a groundbreaking development that merges high-performance engineering with eco-friendly technology. This innovative engine represents a significant leap for the French automotive brand, showcasing its commitment to advancing hydrogen as a viable fuel alternative in the world of motorsport and beyond.

While Japanese automobile company Toyota continues to be leading the hydrogen revolution, other automobile companies are following closely behind. While some have placed all their bets on electric vehicles being the future of sustainable engines, others are looking at ways to continue producing the internal combustion engine. The answer may be found in hydrogen technology whereby traditional internal combustion engines can be adapted to support the alternative fuel source.

Alpine previously introduced a hydrogen powered car in 2022. Now, the newer model is twice as powerful as the last. The car features a 3.5-litre, twin-turbo V6 engine. It produces a power output of 740bhp, and can reach up to 9,000rpm with 770 Nm of torque. The two hydrogen engines are located in the sidepods and behind the cockpit. The model has been in the works for two years and is a testament to Alpine’s continued dedication towards sustainability.

Mental Fatigue Triggers Compensatory Brain Mechanisms

Posted by in category: neuroscience

New research reveals that prolonged mental load weakens brain connectivity, but compensatory mechanisms keep cognitive performance steady.


Summary: A recent study shows that prolonged mental exertion weakens connectivity between the brain’s frontal and parietal lobes, impacting cognitive efficiency. However, the brain has built-in compensatory mechanisms that adjust neural connections to preserve function under fatigue.

Researchers observed this in participants completing memory tasks of varying difficulty; while fatigue slowed performance on simple tasks, complex tasks triggered compensatory adjustments. Findings suggest that these mechanisms allow the brain to optimize resources based on task complexity.
