A New Dental Procedure Could Eliminate Tooth Loss

Posted by in categories: bioengineering, biotech/medical, life extension

Tooth loss is a concern that most people will face at some point in their life. According to studies, by the age of 74, 26 percent of adults will have lost all of their permanent teeth. Dentures are sufficient, but they’re uncomfortable and dental implants can fail and have no ability to “remodel” as the surrounding jaw bone changes with age.

All of these are reasons why some people have placed their hope in stem cell research. While there are controversy surrounds the new medical method such as the use and destruction of human embryos, not all research involves human tissue and has the potential to change a lot of lives.

A new technique being tested in the Tissue Engineering and Regenerative Medicine Laboratory of Dr. Jeremy Mao, Edward V. Zegarelli prof of odontology, and a professor of biomedical engineering at Columbia University, could make “tooth loss” a thing of the past. The cluster believes they need to find some ways to own the body’s stem cells, migrate it to a three-dimensional scaffold manufactured from natural material and insert it to a patient’s mouth.

7 Billion-Year-Old Stardust Is Oldest Material Found on Earth

Posted by in categories: asteroid/comet impacts, existential risks, space travel

Scientists recently identified the oldest material on Earth: stardust that’s 7 billion years old, tucked away in a massive, rocky meteorite that struck our planet half a century ago.

This ancient interstellar dust, made of presolar grains (dust grains that predate our sun), was belched into the universe by dying stars during the final stages of their lives. Some of that dust eventually hitched a ride to Earth on an asteroid that produced the Murchison meteorite, a massive, 220-lb. (100 kilograms) rock that fell on Sept. 28, 1969, near Murchison, Victoria, in Australia.

Could A Pill Replace Exercise? Scientists Discover Protein Mimics Effects Of Working Out

Posted by in categories: biotech/medical, health

ANN ARBOR, Mich. — Given the option, would you avoid the gym altogether and simply pop a pill or drink a supplement that brings about the same benefits as a workout? It sounds farfetched, but the idea of lounging around all day yet still enjoying the health benefits of an intense workout may soon be possible. While there are still many details to be worked out, researchers at the University of Michigan say that the naturally occurring protein Sestrin appears to mimic the effects of exercise on both flies and mice in experimental trials.

These findings could have far reaching implications across the fitness, medical, and scientific fields. For instance, Sestrin could conceivably help individuals unable to work out due to old age or health problems maintain their muscles.

“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” explains Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology, in a release.

Breathtaking Image Shows Powerful Magnetic ‘Ropes’ Surrounding The Whale Galaxy

Posted by in category: space

Sometimes you just have to stand back in awe at the beauty of the Universe – and that’s absolutely the case with this image from the National Radio Astronomy Observatory (NRAO), which captures the side view of a spiral galaxy know as the Whale Galaxy.

But if you look closer, the stunning picture also shows something else: the magnetic ‘ropes’ around the edges of the galaxy’s disc.

These filaments, like cosmic strands of hair, show the galaxy’s magnetic field extending into its halo.

Blood Test to Diagnose Brain Cancer in Development

Posted by in categories: biotech/medical, robotics/AI

Brain cancer remains challenging to diagnose, due to nonspecific symptoms and a lack of cost-effective tests. A new blood test that uses attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy in conjunction with machine learning technology, may help advance the detection of brain cancer.

The patented technology, developed by a team at the University of Strathclyde, uses infrared light to produce a “bio-signature” of a blood sample and applies artificial intelligence to check for the signs of cancer.

The research is published in Nature Communications in a paper titled, “Development of high-throughput ATR-FTIR technology for rapid triage of brain cancer.
