Strava’s Just the Start: The US Military’s Losing War Against Data Leakage

Posted by in category: military

The Defense Department can’t stop the rising river of of digital metadata — or prevent enemies from dipping into it.

The Pentagon has long wrapped Diego Garcia in a veil of secrecy, barring media from the Indian Ocean island even as its base and airfield became a key node in America’s wars in the Middle East. But a hole appeared in the veil last Saturday, when a mobile fitness-tracking app company called Strava posted a heatmap of its subscribers’ activity — including the routes that sailors and airmen take as they jogged.

“What you saw from the running patterns is exactly what I experienced when I was deployed there five times between 1985 and 1999,” Air Force General Paul Selva, vice chairman of the Joint Chiefs of Staff, recalled in a breakfast with reporters on Tuesday. A heavily secluded jungle trail runs along the island’s western edge, Selva said, perfect for an ambush. “I’ve run it a thousand times. If I had a FitBit, I would have contributed to the map of Diego Garcia.”

Engineers develop flexible lithium battery for wearable electronics

Posted by in categories: engineering, mobile phones, wearables

The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays—such as smart phones, tablets, and TV—to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries. Up to now, however, researchers have had difficulty obtaining both good flexibility and high energy density concurrently in lithium-ion batteries.

A team led by Yuan Yang, assistant professor of materials science and engineering in the department of applied physics and mathematics at Columbia Engineering, has developed a prototype that addresses this challenge: a Li-on battery shaped like the human spine that allows remarkable flexibility, high , and stable voltage no matter how it is flexed or twisted. The study is published today in Advanced Materials.

“The density of our prototype is one of the highest reported so far,” says Yang. “We’ve developed a simple and scalable approach to fabricate a flexible spine-like that has excellent electrochemical and mechanical properties. Our design is a very promising candidate as the first-generation, flexible, commercial lithium-ion battery. We are now optimizing the design and improving its performance.”

Researchers report promising pterostilbene and NR clinical trial results

Posted by in categories: biotech/medical, life extension

Results of NR and pterostilbene clinical trial are promising.

A clinical trial of an NR and pterostilbene anti-aging supplement appeared to be safe over the short-term as it increased NAD levels in a sustained way. [This article first appeared on the website Author: Brady Hartman. ]

A clinical trial of NR and pterostilbene sustainably increased NAD levels and appeared to be safe over the short-term. Moreover, the study suggests that it increased the mobility of the aging test subjects.

Could a protein named klotho block aging and dementia?

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

Could a protein called klotho block aging and dementia?

Summary: More klotho means better cognitive function says a scientist. By injecting the protein Klotho into mice with Alzheimer’s, a UCSF researcher improved their brain function. The researcher hopes to eventually apply the treatment to humans to treat aging and dementia. [Introduction by Brady Hartman, followed by a link to the full article.]

Neurologist and neuroscientist Dr. Dena Dubal wants to prevent dementia and aging with a protein called Klotho. Dr. Dubal, MD, Ph.D. – an associate professor of neurology at UC San Francisco – aims to use this novel approach to battle neurodegenerative diseases like Alzheimer’s disease and dementia.

Revolutionary stealth virus holds promise for cancer therapy

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

Researchers solved a problem that has been holding back the use of viral vectors for cancer therapy. They re-engineered viruses with a novel stealth technique that enables them to be used to treat cancer.

Up until now, viral vectors couldn’t be used widely in cancer therapy. Researchers just announced that they re-engineered an adenovirus with a novel stealth technique that enables it to be used to fight tumors. [This article first appeared on the website Author: Brady Hartman. ]

Viral vectors are well-developed tools used by scientists to deliver genetic material into cells. Unfortunately, they haven’t worked well to treat cancer until a group of researchers in Switzerland re-engineered them to enable them to be used in cancer therapy.

Developing a Science-based Personal Longevity Strategy

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

When developing any personal health and longevity strategy it is essential to apply the scientific method.

There is one common public reaction to my talks that bothers me quite a bit. I am worried that after each of my lectures, people will just start taking lots of anti-aging pills without regard for dosage or effectiveness, potentially hurting themselves in the process.

This is because one of the most common reactions to me mentioning any currently available interventions is to search for each and every component and order them all right away. Whatever I say about safety and the need to test before people make any changes in their lifestyles seems ineffective.

Researchers Cure Lung Fibrosis in Mice With a Single Gene Therapy

Posted by in categories: biotech/medical, life extension

Idiopathic pulmonary fibrosis is a disease associated with critically short telomeres, and it currently lacks a reliable and effective treatment. Researchers at the Telomere and Telomerase Group at the Spanish National Cancer Research Centre (CNIO) have cured the disease in mice using telomerase therapy to lengthen short telomeres.

A proof of concept for an effective treatment against pulmonary fibrosis

The authors of this study have stated that this is a “proof of concept that telomerase activation represents an effective treatment against pulmonary fibrosis” in their publication[1].

A Chinese satellite just used quantum cryptography to make an unhackable video call between Beijing and Vienna

Posted by in categories: cybercrime/malcode, encryption, quantum physics, space

The Chinese “Micius” satellite has successfully set up the world’s most secure video conference, using quantum cryptography to connect scientists in Europe and China for an unhackable, intercontinental chat.

The feat marks another milestone for the satellite, officially called Quantum Experiments at Space Scale (QESS), which only last year was making headlines for transmitting an “unbreakable” quantum code to the Earth’s surface.
