Exercise Reverses Age‐Related Decline in NAD+ Salvage Capacity

Exercise really does influence how we age, and a new study shows how regular exercise in later life can help offset the decline of NAD+ and NAMPT, two important molecules that facilitate cellular energy production, in skeletal muscle.

NAD+ and mitochondria

The mitochondria are the power stations of the cell and provide the energy that our cells need in order to function. As we age, our mitochondria become increasingly dysfunctional and inefficient, and they produce excessive waste in the form of free radicals, which bounce around the interior of the cell, striking and damaging the cellular machinery within.

Researchers solve mystery of how gas bubbles form in liquid

The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those water droplets are uniform in their size and spacing, bubble formation is typically a much more random process.

Now, a study by researchers at MIT and Princeton University shows that under certain conditions, bubbles can also be coaxed to form spheres as perfectly matched as droplets.

The new findings could have implications for the development of microfluidic devices for biomedical research and for understanding the way interacts with petroleum in the tiny pore spaces of underground rock formations, the researchers say. The findings are published today in the journal PNAS, in a paper by MIT graduate Amir Pahlavan Ph.D. ‘18, Professor Howard Stone of Princeton, MIT School of Engineering Professor of Teaching Innovation Gareth McKinley, and MIT Professor Ruben Juanes.

Former Area 51 Scientist Discloses Projects That have Never Been Seen by the Public

Space technology expert and former Area 51 rocket designer David Adair will show you visuals and graphics of what the Aerospace Community had intended to build in space with the Shuttle program. These projects have never been seen before or announced to the public.

Learn about: Space Stations, Space Manufacturing, Space Based Medicines and Micro-Gravity Processing that the Aerospace Corporations wanted to build but were told NO by NASA because it was ‘too much industrialization of space’. Prepare to be amazed at the possibilities that exist! Meet and hear from one of the most exceptional rocket scientists of our time.

Performance-enhancing bacteria found in the microbiomes of elite athletes

New research has identified a type of bacteria found in the microbiomes of elite athletes that contributes to improved capacity for exercise. These bacteria, members of the genus Veillonella, are not found in the guts of sedentary people.

By taking a closer look at the bacteria, the researchers from Joslin Diabetes Center determined Veillonella metabolizes produced by and converts it into propionate, a short chain fatty acid. The then utilizes that propionate to improve exercise capacity. The results were reported today in Nature Medicine.

“Having increased exercise capacity is a strong predictor of overall health and protection against cardiovascular disease, diabetes, and overall longevity,” says Aleksandar D. Kostic Ph.D., TITLE., a co-author on the paper. “What we envision is a probiotic supplement that people can take that will increase their ability to do meaningful exercise and therefore protect them against chronic diseases including diabetes.”

Cancer patients welcome breakthrough ‘living drug’ that reprograms immune systems to fight disease

In a groundbreaking treatment, cancer patients’ immune systems are being genetically reprogrammed to fight their terminal cancer for them, with promising results.

In the UK, a number of National Health Service (NHS) patients with lymphoma at King’s College Hospital have been given CAR-T, a “living drug” that is unique to each patient as it contains some of their own cells.
