Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron – an object traveling so fast it could circle the Earth many times in a second. Researchers at the University of Arizona have developed the world’s fastest electron microscope that can do just that.

They believe their work will lead to groundbreaking advancements in physics, chemistry, bioengineering, materials sciences and more.

“When you get the latest version of a smartphone, it comes with a better camera,” said Mohammed Hassan, associate professor of physics and optical sciences. “This transmission electron microscope is like a very powerful camera in the latest version of smartphones; it allows us to take pictures of things we were not able to see before – like electrons. With this microscope, we hope the scientific community can understand the quantum physics behind how an electron behaves and how an electron moves.”

The microbiome has a profound impact on host health that extends to the host’s young ones. Studies in mice have shown that maternal gut bacteria play a role in offspring behavior and placental growth during pregnancy.^1,2 Yet, the effects of the paternal microbiome on the health of their progeny remained relatively unexplored.

In a new study, scientists found that altering the gut microbiome of male mice negatively affected the health and lifespan of their offspring through epigenetic changes in the sperm.³ The results, published in Nature, offer insights into a gut-germline axis that mediates the effects of the microbiome on health and disease across generations.

A new proposal borrows from the principles of quantum mechanics and a technique called “wavelength multiplexing” to hypothesize an ultra-dense new storage format.

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.

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.

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.

China has taken significant steps toward developing high-speed transportation after testing a maglev train in a vacuum tube.

China’s groundbreaking maglev train, capable of reaching speeds up to 1,000 km/h, and its potential impact on global transportation and the environment.

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.

In an interview to Moneycontrol, Meta’s Yann LeCun expressed optimism about the benefits of artificial intelligence and calls out any harm arising from it as ‘science fiction’ at this point.
