Scientists have found a way to levitate objects with light

Posted by in categories: nanotechnology, space travel

Turns out the key to making things lighter than air is…light!

California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel spacecraft farther than they’ve ever traveled before, according to a report.

Researchers at the California Institute of Technology believe that by covering the surfaces of objects with microscopic nanoscale patterns specially designed to interact with beams of light, they could be propelled without fuel — and potentially by light sources millions of miles away, according to Phys.org.

Light coaxes stem cells to repair teeth: Noninvasive laser therapy could radically shift dental treatment

Posted by in categories: biotech/medical, life extension

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by Wyss Institute Core Faculty member David Mooney, Ph.D., lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

Research paves way for new source for leukemia drug

Posted by in categories: biotech/medical, chemistry

Chemistry researchers at Oregon State University have patented a method for making anti-leukemia compounds that until now have only been available via an Asian tree that produces them.

The synthesis of cephalotaxine and homoharringtonine (HHT) paves the way toward less-expensive, more readily available leukemia drugs whose production is not subject to the risks and inefficiencies associated with harvesting .

Also, the synthesis of cephalotaxine opens the door to preparing other, structurally related compounds for evaluation as potential new cancer drugs.

NMN, NAD+ and the Plasma Membrane

Posted by in categories: biotech/medical, genetics, life extension, robotics/AI

Earlier this year, we hosted the Ending Age-Related Diseases 2018 conference at the Cooper Union, New York City. This conference was designed to bring together the best in the aging research and biotech investment worlds and saw a range of industry experts sharing their insights.

Joe Betts Lacroix of Y Combinator and Vium discusses the different ways in which entrepreneurs can focus on overcoming the diseases of aging, namely direct, indirect, and money-first approaches, and the strengths and weakness of each.

Joe was the primary technical founder of hardware/software startup OQO, which entered the Guinness Book of World Records for building the smallest fully featured PC. His experience spans from biotech research to electronics design. Very experienced in invention, prosecution and monetization of intellectual property, he has over 80 patents granted and pending in fields ranging from biophysics and safety systems to antennas, thermal systems, user interfaces, and analog electronics. He has written numerous peer-reviewed publications in fields such as biophysics, genetics, electronics, and robotics. Joe holds a Harvard A.B., an MIT S.M. and a Caltech research fellowship.

Gut Bacteria Contribute to Vascular Aging

Posted by in categories: biotech/medical, life extension

A new publication from researchers at the University of Colorado Boulder shows how gut bacteria increase the risk of cardiovascular disease by contributing to the stiffening of the blood vessels during aging. This study is the first to demonstrate that changes to the gut microbiome promote vascular aging and harm health [1].

The researchers treated groups of young and old mice with a range of antibiotics that are known to kill gut bacteria. Following this, they examined the vascular systems of the mice, particularly the lining of the blood vessels (endothelium) and the stiffness in their large arteries. Additionally, the researchers measured a number of biomarkers, including free radicals, antioxidants, pro-inflammatory cytokines, and nitric oxide in the blood.

After 3–4 weeks of treatment, the researchers once again measured the biomarkers and looked at the vascular system. There was no change in the young group of mice; however, the old mice saw significant improvement in both vascular health and biomarkers. The researchers note that the treatment had suppressed the microbiome of the aged mice and, in doing so, improved their health. Therefore, they concluded that something in the microbiome of old mice was contributing to vascular aging.
