Earth Is Getting Hit by Too Much Antimatter, and Nobody Knows Why

Posted by in categories: particle physics, space

Amid the high speed cosmic rays raining down on us from the depths of space are a handful of antimatter particles called positrons.

Astronomers think that Earth is showered by these ‘anti-electrons’ because of pulsars, but there’s a weird catch – there are more of these particles coming at us than there should be. And now, thanks to a new study, we might finally get some answers.

Cosmic rays are incredibly fast particles, since they’re being shot down from space at high energies. Positrons make up a small percent of these super speedy particles, but nobody is entirely sure where or how they’re made.

Istvan Contra McAfee

Posted by in categories: business, geopolitics, life extension, transhumanism

This is a fun new story to read, and highlights some interesting philosophical differences, especially as McAfee and I look at 2020 campaign possibilities: https://logosclubblog.com/2018/11/06/istvan-contra-mcafee/ #transhumanism


During 2016 presidential race, the majority of the US public were spellbound by the unlikely rise of Donald Trump and Bernie Sanders and their various competing visions for the United States of America. Considerably less institutionally-heeled but far more imaginative and, some argued, outlandish, candidates, dead-ringer for the Dos Equis Man John David McAfee of The Cyber Party and Zoltan Istvan Gyurko of The Transhumanist Party. McAfee, a successful tech entrepreneur who worked with NASA between 1968 and 1970, was the more well-known of the two politicians, principally through the popularity (or infamy, depending on who one asked) of McAfee Antivirus Software. McAfee (the person, not the software) has also received a good deal of airtime and media attention for a scandal which saw him accused of murder and fleeing from the corrupt, Sinaloa-controlled Belize after the errant businessman found out about a government-sponsored plot to kill him.

Zoltan Istvan, a former NatGeo journalist and the founder of the US Transhumanist Party, though less well known than McAfee, garnered significant attention due to both his extraordinary statements concerning technological advancement and a 2015 four month campaign, wherein he drove around the country in a brown, coffin-shaped bus (dubbed ‘The Immortality Bus’) to bring awareness to his goal of working to end death itself through radical life-extension procedures. The Immortality Bus tour ended December 14, 2015, with Mr. Istvan delivering the Transhumanist Bill of Rights to the US Capitol Building in Washington, DC. The Verge dubbed him, a “modern-day Ken Kesey” referencing the beat generation countercultural figure, well known for his novel, One Flew Over The Cuckoo’s Nest. The comparison was not entirely inaccurate as Istvan was also a novelist, having penned the highly contentious sci-fi novel, The Transhumanist Wager, in 2013.

Culture may explain why brains have become bigger

Posted by in categories: economics, neuroscience

A theory called the cultural brain hypothesis could explain extraordinary increases in brain size in humans and other animals over the last few million years, according to a study published in PLOS Computational Biology by Michael Muthukrishna of the London School of Economics and Political Science and Harvard University, and colleagues at the University of British Columbia and Harvard University.

Embryos remember the chemicals that they encounter

Posted by in category: biological

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are cultivated over the course of development.

According to the study, published in eLife, cells retain a memory of the chemical signals to which they are exposed. And, the researchers show, embryos that fail to form these memories remain a clump of clones, never realizing their unique biological potential.

Custom-Grown Bones, and Other Wild Advances in Regenerative Medicine

Posted by in categories: biotech/medical, life extension

The human body has always been an incredible machine, from the grand feats of strength and athleticism it can accomplish down to the fine details of each vein, nerve, and cell. But the way we think about the body has changed over time, as has our level of understanding of it.

In Nina Tandon’s view, there have been two different phases of knowledge here. “For so much of human history, medicine was about letting the body come to rest, because there was an assumed proportionality attributed to the body,” she said.

Then, around the turn of the last century, we started developing interchangeable parts (whether from donors, or made of plastic or metal), and thinking of our bodies a bit more like machines. “We’re each made out of 206 bones held together by 360 joints,” Tandon said. “But many of us are more than that. By the time we go through this lifetime, 70 percent of us will be living with parts of our body that we weren’t born with.”

MIT plans for a giant laser ‘porch light’ in space to attract aliens

Posted by in category: alien life

A pair of MIT researchers has proposed a radical method for making our presence known in the universe.

In a new feasibility study, the team says it could be possible to use laser technology as a beacon to attract the attention of alien astronomers, much like a planetary-scale porch light.
