“The positive conclusion of our preliminary design review marks a major milestone in SABRE development,” Mark Ford, heading ESA’s Propulsion Engineering section, said in a statement. “It confirms the test version of this revolutionary new class of engine is ready for implementation.”

NOTE FROM TED: We’ve flagged this talk, which was filmed at a TEDx event, because it appears to fall outside TEDx’s curatorial guidelines. There is no conclusive research that supports the claims made about the subconscious mind. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf
Surviving an accident was the easy part; coping with the chronic pain would prove more difficult. Danna Pycher shares her story about trauma and the transformative insight she gained that allowed her to harness the healing power of the subconscious mind.
Danna Pycher is a certified Neuro-Linguistic Hypnotherapist specializing in chronic illness and trauma. She is also a motivational speaker and coach. Her first book 3rd Generation and Beyond is a beautiful, powerful book of life philosophies according to a third generation Holocaust descendant. ” A must read for the young and old who are trying to find an identity or just need a reminder on how to appreciate the little things in life.” She enjoyed many years in broadcasting as an on-camera host, reporter, and producer working in the fields of health reporting and corporate productions. Her curiosity about the nature of human beings is what guides her professional pursuits.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
A cheap, common drug could save hundreds of thousands of lives a year if used routinely, doctors say.
London is the latest city to gain a city bench with the ability to absorb as much pollution as a small forest. The vertical garden, which doubles as a bench, is Green City Solutions’ CityTree. Using a vertical installation of moss, the bench can absorb as much pollution as 275 trees in 1 percent of the space.
The World Health Organization estimates that 7 million premature deaths occur each year from air pollution, making it one of the largest environmental health risks in the world.
By and Targeting Metabesity to examine the links between metabesity, Longevity and the USA’s current health shortfalls, including low health-adjusted life expectancy (“HALE”) and the large gap between HALE and life expectancy, despite its extremely high per-capita healthcare expenditures, and to chart policy recommendations to neutralize this vast health vs wealth deficit.
Metabesity and Longevity: USA Special Case Study is an 85-page open-access analytical report produced jointly by Aging Analytics Agency and Targeting Metabesity to examine the links between metabesity, Longevity and the USA s current health shortfalls, including low health-adjusted life expectancy ( HALE ) and the large gap between HALE and life expectancy, despite its extremely high per-capita healthcare expenditures, and to chart policy recommendations to neutralize this vast health vs wealth deficit.

As the issue of aging population intensifies, sick care will become increasingly expensive and ineffective. America needs to rapidly deploy a government-led shift from treatment to prevention, and from prevention to precision health, using deep diagnostics and prognostics in combination with biomarkers of aging, metabesity, health and intervention-effectiveness, to delay the onset of disease with as minimal intervention as possible, as early as possible. Seeking synergies between Longevity research, P4 (preventive, personalized, precision and participatory) medicine and Artificial Intelligence has the potential to enable rapid and widespread policy and infrastructural reforms for USA healthcare to quickly boost National Healthy Longevity, but only with sufficient government commitment.
Each year, heart attacks kill almost 10 million people around the world, and more than 6 million die from stroke. A heart attack is caused by clots that block arterial blood flow. Tissues are deprived from blood-borne oxygen. Under these conditions, the affected tissues undergo a rapid necrosis. But why? Scientists at the University of Geneva (UNIGE), Switzerland, the University of Lyon and the Institut National de la Santé et de la Recherche Médicale (Inserm), France, have discovered that the synthesis of a lipid called deoxydihydroceramide provokes necrosis. This lipid accumulates in the absence of oxygen and blocks cellular functions. By inhibiting its synthesis in a mouse suffering a heart attack, the biologists were able to reduce the tissue damage by 30 percent. These results, published in Nature Metabolism, suggest a new model of treatment for victims of heart attack or stroke.
“But what causes necrosis under these conditions?” asked Howard Riezman, professor in the Department of Biochemistry of the Faculty of Science at UNIGE and Director of the NCCR Chemical Biology. Not all animals are so sensitive to the absence of oxygen—worms can live three days without oxygen, some turtles can live several months, and certain bacteria indefinitely.
“That is why we sought to find the link between the lack of oxygen and tissue necrosis in mammals,” said the scientist.
We’re continuing to release talks from Ending Age-Related Diseases 2019, our highly successful two-day conference that featured talks from leading researchers and investors, bringing them together to discuss the future of aging and rejuvenation biotechnology.
Dr. Peter Fedichev, co-founder of GERO, discussed biomarkers in the context of mouse research, particularly physiological frailty and blood cell counts. He introduced a new index, the Dynamic Frailty Index, and explained it in detail, including the advantages that it has over conventional frailty models and epigenetic clocks. He also explained the differences between humans and mice, most notably the fact that interventions that work in mice do not always apply to human beings.
Brain-machine interface enthusiasts often gush about “closing the loop.” It’s for good reason. On the implant level, it means engineering smarter probes that only activate when they detect faulty electrical signals in brain circuits. Elon Musk’s Neuralink—among other players—are readily pursuing these bi-directional implants that both measure and zap the brain.
But to scientists laboring to restore functionality to paralyzed patients or amputees, “closing the loop” has broader connotations. Building smart mind-controlled robotic limbs isn’t enough; the next frontier is restoring sensation in offline body parts. To truly meld biology with machine, the robotic appendage has to “feel one” with the body.
This month, two studies from Science Robotics describe complementary ways forward. In one, scientists from the University of Utah paired a state-of-the-art robotic arm—the DEKA LUKE—with electrically stimulating remaining nerves above the attachment point. Using artificial zaps to mimic the skin’s natural response patterns to touch, the team dramatically increased the patient’s ability to identify objects. Without much training, he could easily discriminate between the small and large and the soft and hard while blindfolded and wearing headphones.
New research from North Carolina State University shows that unique materials with distinct properties akin to those of gecko feet—the ability to stick to just about any surface—can be created by harnessing liquid-driven chaos to produce soft polymer microparticles with hierarchical branching on the micro- and nanoscale.
The findings, described in the journal Nature Materials, hold the potential for advances in gels, pastes, foods, nonwovens and coatings, among other formulations.
The soft dendritic particle materials with unique adhesive and structure-building properties can be created from a variety of polymers precipitated from solutions under special conditions, says Orlin Velev, S. Frank and Doris Culberson Distinguished Professor of Chemical and Biomolecular Engineering at NC State and corresponding author of the paper.
