New research in the journal Nature Aging takes a page from the field of renewable energy and shows that genetically engineered mitochondria can convert light energy into chemical energy that cells can use, ultimately extending the life of the roundworm C. elegans. While the prospect of sunlight-charged cells in humans is more science fiction than science, the findings shed light on important mechanisms in the aging process.

“We know that is a consequence of aging,” said Andrew Wojtovich, Ph.D., associate professor of Anesthesiology and Perioperative Medicine and Pharmacology & Physiology at the University of Rochester Medical Center and senior author of the study.

“This study found that simply boosting metabolism using light-powered gave laboratory worms longer, healthier lives. These findings and new research tools will enable us to further study mitochondria and identify new ways to treat age-related diseases and age healthier.”

Sensing systems are becoming prevalent in many areas of our lives, such as in ambient-assisted health care, autonomous vehicles, and touchless human-computer interaction. However, these systems often lack intelligence: they tend to gather all available information, even if it is not relevant. This can lead not only to privacy infringements but also to wasted time, energy, and computational resources during data processing.

To address this problem, researchers from the French CNRS came up with a concept for intelligent electromagnetic sensing, which uses machine-learning techniques to generate learned illumination patterns so as to pre-select relevant details during the measurement process. A programmable metasurface is configured to generate the learned patterns, performing high-accuracy sensing (e.g., posture recognition) with a remarkably reduced number of measurements.

But measurement processes in realistic applications are inevitably subject to a variety of . Noise fundamentally accompanies any measurement. The signal-to– can be particularly low in indoor environments where the radiated electromagnetic signals must be kept weak.

Philosophy of the future is needed.

The world is chancing fast. (AI, genome sequencing, demographics changes…)

Fascism, Communism, Capitalism and other ideologies and economic system of past may not be ideal to ensure a flourishing human civilization on Earth and beyond.

Some initial thoughts on a framework of a philosophy of the future.

Findings underline the importance of a strength-based rather than a deficit-based focus on aging and older adults.

What are the keys to “successful” or optimal aging? A new study followed more than 7,000 middle-aged and older Canadians for approximately three years to identify the factors linked to well-being as we age.

They found that those who were female, married, physically active, and not obese and those who had never smoked, had higher incomes, and who did not have insomnia, heart disease or arthritis, were more likely to maintain excellent health across the study period and less likely to develop disabling cognitive, physical, or emotional problems.

I’m so waiting for it! Let the new year go along the path of compassion.

For all who would like to stop animall suffer and still have their favourite meal. There is still a lot of work to be done to make this happen, but much has already been done.

A California-based lab-grown meat start-up received the first green light for such products from the U.S. food safety agency on No. 16, although the product still has more hurdles to clear before being sold to consumers.

Since the discovery of black holes, they have inspired images of the universe’s extremities in both scientists and storytellers. Their immense gravity — sucking in any matter and light unfortunate enough to come within grabbing distance — conjures images of crushing death and infinite possibility.

That same gravity, however, creates a well which consumes indiscriminately and from whence nothing can ever emerge. The only trouble is that isn’t the case. Among Stephen Hawking’s many accomplishments was the discovery that black holes actually radiate very slowly and will eventually evaporate. This discovery, while enough to make Hawking famous, threw a wrench in contemporary astrophysics by creating a paradox.

If a black hole compresses into a singular point at its center and is surrounded by a gravitational event horizon, then the radiation emerging from the horizon is necessarily separate from the matter in the middle. In short, that radiation contains none of the information related to the matter which fell inside. If that’s true, then causality essentially breaks down around a black hole and physicists didn’t like that one bit.

Year 2011 face_with_colon_three

It was only a year ago that ACell’s “miracle powder” was sprinkled on amputated fingers and shown to stimulate the regeneration of fingertips. The world was both awed and skeptical of the powder’s regenerative power, touting that it would revolutionize regenerative medicine or calling it was quack science.

A fingertip is one thing. A thigh, quite another.

After losing most of his thigh muscle in a battlefield explosion, one marine was given a second chance when another such miracle powder caused much of his thigh to grow back. It’s not only a wonderful feel-good story, but demonstrating that the same substance can grow back different tissues suggests that we may have only seen a small part of its full regenerative potential.
