Sept 25 (Reuters) — The chief executive officer of Jeff Bezos’s space company Blue Origin, Bob Smith, will step down at the end of the year to be replaced by former Amazon executive Dave Limp, who ran products such as Kindle, according to emails seen by Reuters.

Limp, a former senior vice president at Amazon who led the company’s consumer devices unit, will become Blue Origin’s CEO on Dec. 4, an email from Bezos, Blue Origin’s founder, said.

“Jeff and I have been discussing my plan for months,” Smith told employees in an email sent Monday. He added he would remain with the company until Jan. 2 “to ensure a smooth transition with the new CEO.”

Is there an 8-dimensional “engine” behind our universe? Join Marion Kerr on a fun, visually exciting journey as she explores a mysterious, highly complex structure known simply as ‘E8’–a weird, 8-dimensional mathematical object that for some, strange reason, appears to encode all of the particles and forces of our 3-dimensional universe.

Meet surfer and renowned theoretical physicist Garrett Lisi as he rides the waves and paraglides over the beautiful Hawaiian island of Maui and talks about his groundbreaking discovery about E8 relates deeply to our reality; and learn why Los Angeles based Klee Irwin and his group of research scientists believe that the universe is essentially a 3-dimensional “shadow” of this enigmatic… thing… that may exist behind the curtain of our reality.

In a recent study published in Science Advances, researchers from the California Institute of Technology, led by Dr. Wei Gao, have developed a machine learning (ML)–powered 3D-printed epifluidic electronic skin for multimodal health surveillance. This wearable platform enables real-time physical and chemical monitoring of health status.

Wearable health devices have the potential to revolutionize the medical world, offering real-time tracking, personalized treatments, and early diagnosis of diseases.

However, one of the main challenges with these devices is that they don’t track data at the molecular level, and their fabrication is challenging. Dr. Gao explained why this served as a motivation for their team.

Dopamine seems to be having a moment in the zeitgeist. You may have read about it in the news, seen viral social media posts about “dopamine hacking,” or listened to podcasts about how to harness what this molecule is doing in your brain to improve your mood and productivity. However, recent neuroscience research suggests that popular strategies to control dopamine are based on an overly narrow view of how it functions.

Dopamine is one of the brain’s neurotransmitters — tiny molecules that act as messengers between neurons. It is known for its role in tracking your reaction to rewards such as food, sex, money, or answering a question correctly. There are many kinds of dopamine neurons located in the uppermost region of the brainstem that manufacture and release dopamine throughout the brain. Whether neuron type affects the function of the dopamine it produces has been an open question.

Recently published research reports a relationship between neuron type and dopamine function, and one type of dopamine neuron has an unexpected function that will likely reshape how scientists, clinicians, and the public understand this neurotransmitter.

People in the oldest stage of life who regularly engage in aerobic activities and strength training exercises perform better on cognitive tests than those who are either sedentary or participate only in aerobic exercise. That is the key finding of our new study, published in the journal GeroScience.

We assessed 184 cognitively healthy people ranging in age from 85 to 99. Each participant reported their exercise habits and underwent a comprehensive battery of neuropsychological tests that were designed to evaluate various dimensions of cognitive function.

We found that those who incorporated both aerobic exercises, such as swimming and cycling, and strength exercises like weightlifting into their routines – regardless of intensity and duration – had better mental agility, quicker thinking and greater ability to shift or adapt their thinking.
