Live longer and die better

Posted by in categories: biotech/medical, life extension

This is the moment at which I press Dr Leeson to come clean and tell me if I might live to 300 because of pluripotent stem cells that could be set free to regrow or recreate bits of my anatomy as they wear out. Is this science fiction or is this real, I ask?

‘It’s real — it’s already happening…’

Oxford Today talks to the Director of the Oxford Institute of Ageing, Dr George Leeson.

A Biologists Review of Juvenescence: Investing in the Age of Longevity

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

Jim Mellon and Al Chalabi are back with another successful venture into the world of science investment. Following their acclaimed 2012 book “Cracking the code”, whose spotlight was on the life sciences industry, Juvenescence takes us on a compelling journey through the dawning market of longevity and rejuvenation biotechnology, which the authors predict will be the biggest “money fountain” to hit the financial world in the coming years.

Juvenescence is a visionary book, debunking the sometimes questionable past of longevity research and steering us towards a ‘brave new world’ in which advances in medicine are already leading to clinical trials whose aim is to extend human lifespan to unprecedented levels.

Mellon and Chalabi come across as eloquent devotees of cold, hard science, and for a book targeted primarily at investors, biologists and experts will be hard-pressed to find inaccuracies in the many heavily technical sections. The authors explain the science of aging in an engaging and accessible manner, bridging the gap between the lab and the public with ease and tact. They employ elegant metaphors to explain complex processes as well as some light-hearted ones, including the “Deadly Quintet”, which reads more like the title of a long-lost Tarantino film, or the “Actuarial Escape Velocity”, a reference to the controversial “Longevity Escape Velocity” promoted by Aubrey de Grey. Mellon and Chalabi use state-of-the-art research whenever possible, with recent, fresh-from-the-lab studies making up the majority of sources.

Facing poverty, academics turn to sex work and sleeping in cars

Posted by in categories: health, security, sex

Adjuncting has grown as funding for public universities has fallen by more than a quarter between 1990 and 2009. Private institutions also recognize the allure of part-time professors: generally they are cheaper than full-time staff, don’t receive benefits or support for their personal research, and their hours can be carefully limited so they do not teach enough to qualify for health insurance.

Adjunct professors in America face low pay and long hours without the security of full-time faculty. Some, on the brink of homelessness, take desperate measures.

Russian operatives used Facebook ads to exploit divisions over Black Lives Matter, Muslims

Posted by in category: government

The batch of more than 3,000 Russian-bought ads that Facebook is preparing to turn over to Congress shows a deep understanding of social divides in American society, with some ads promoting African-American rights groups including Black Lives Matter and others suggesting that these same groups pose a rising political threat, say people familiar with the covert influence campaign.

The Russian campaign — taking advantage of Facebook’s ability to simultaneously send contrary messages to different groups of users based on their political and demographic characteristics — also sought to sow discord among religious groups. Other ads highlighted support for Democrat Hillary Clinton among Muslim women.

Lockheed Martin unveils fully reusable crewed Martian lander

Posted by in category: space travel

NASA’s goal to reach Mars is just over a decade away, and Lockheed Martin revealed Thursday how humans might soon walk upon the red planet’s surface.

Lockheed Martin gave CNBC a first look at its new spacecraft prototype, which the company will unveil Thursday at this year’s International Astronautical Congress in Adelaide, Australia.

“This is a single-stage, completely reusable lander which will be able to both descend and ascend,” said Lockheed Martin’s Robert Chambers.

Traversable acausal retrograde domains in spacetime

Posted by in category: time travel

This was the second scholarly paper i saw this year about time travel. Posting because there isn’t nearly enough serious interest about Time Travel in the science community.

Traversable acausal retrograde domains in spacetime.
Benjamin K Tippett1 and David Tsang2
Published 31 March 2017 •

In this paper we present geometry which has been designed to fit a layperson’s description of a ‘time machine’. It is a box which allows those within it to travel backwards and forwards through time and space, as interpreted by an external observer. Timelike observers travel within the interior of a ‘bubble’ of geometry which moves along a circular, acausal trajectory through spacetime. If certain timelike observers inside the bubble maintain a persistent acceleration, their worldlines will close.

Machs Effect interstellar propellentless propulsion mission proposal at NASA NIAC

Posted by in categories: materials, space travel

Finally Mach Effect propulsion had gotten useful levels of funding and will get a validation test with NASA. They reported interim results and have made good progress. Nextbigfuture covered the announcement of funding by NASA NIAC for mach effect propulsion in April 2017. They now have presented the new experiments and path forward with the needed materials to clearly prove significant propulsion and unambiguous space experiments. They have advanced the experimental work and will get test state-of-the-art PIN-PMN-PT materials. They have demonstrated a Force versus Voltage scaling relationship that is consistent with the theory. They have a roadmap to continue.

Google Brain chief: AI tops humans in computer vision, and healthcare will never be the same

Posted by in categories: robotics/AI, transportation

Just five years ago, artificial intelligence-enabled computers could barely recognize images fed to them, much less analyze them anything like people can. But suddenly, they’ve turned the tables.

“In 2011 their error rate was 26 percent,” says Jeff Dean, chief of the Google Brain project, which along with other tech giants has helped lead a recent revolution in image recognition as well as speech recognition and self-driving cars. Now, he says, computers’ ability to view and analyze images (pictured) exceeds what human eyes can do.

“If you ’ d have told me that would be a possible just a few years ago, I would ’ ve never believed you,” Dean said during an appearance at a research event in Heidelberg, Germany. But thanks to AI-enabled computer vision advances, computers “can now see … and that has opened our eyes (about) what is possible.”
