POPSPhysicists Demonstrate How Information Can Escape From Black Holes Hawking's idea was generally accepted by physicists until the late 1990s, when many began to doubt the assertion. Even Hawking himself renounced the idea in 2004. Yet no one, until now, has been able to provide a plausible mechanism for how information might escape from a black hole. A team of physicists led by Abhay Ashtekar, Holder of the Eberly Family Chair in Physics and director of the Penn State Institute for Gravitation and the Cosmos, now has discovered such a mechanism. Broadly, their findings expand space-time beyond its assumed size, thus providing room for information to reappear.

POPSTranshumanism vs. Trans-Systemism What exactly is this “human” that we are supposed to extrapolate into the future? Is it an individual animal? A member of a species? A self-aware “software” that resides in the fore brain of an advanced mammal? Several combined pieces of software? Software combined with external knowledge and information? Does it depend on nature? Can it be distinguished form the system in which it resides? Can it exist without the broader system? ******** Perhaps the most critical challenge of transhumanist philosophy is exactly this: To offer a vision of the future human, the human of beyond. Transhumanism will not grow into a mature philosophy without defining and describing the possible favorable directions of human evolution, both as individuals and as a specie.

POPSGenetically modified human embryo stirs criticism It is definitely unacceptable to try it when it is unsafe. It is definitely worth trying when it will be safe. It will be safe eventually, our job meanwhile is to create an adequate ethical framework that will allow the harnessing of this future technology to the benefit of all humans and other beings.

POPSNew twist to matter-antimatter mystery Here is an "almost breakthrough" A major mystery of modern physics is why normal matter particles are the building blocks of the observable universe. Why are we not made of antimatter? Or pure energy? Scientists speculate that a tiny imbalance in the early universe allowed a small fraction of normal matter – one particle for every one billion – to avoid annihilation and survive to form stars, planets, and humans. When we come to know that we don't know, there is a new place for hope...

POPSWill giant vegetables help solve world food shortage? Scientists have yet to offer a definitive explanation of why space causes the seeds to mutate but they believe that cosmic radiation, micro-gravity and magnetic fields may play a part. Mr Lo said: "After space travel the genetic sequence may change from 1,2,3,4 to 1,2,4,3 or a gene may even disappear so 1,2,3,4 becomes 1, 2, and 4. "We don't think there is any threat to human health because the genes themselves do not mutate, just their sequence changes. "With genetically-modified crops you have seen environmental problems because they have added genes that can damage other organisms. "But with space seeds they don't gain genes, they can only lose them."

POPSQuantum computers take step toward practicality In computing, a logic gate is built to accept a set of inputs and, depending on their properties, provide a specific output. In the binary logic found in today's electrical computers, a certain gate will yield a "1" only if all of its inputs are "1"s. Otherwise it will yield a "0." Similarly, a quantum photonic gate would work by detecting the properties of input photons from two light beams, called "control" and "signal," and then producing an output based on those, such as by flipping the polarization of one of the input photons.

POPSA Game worthwhile playing ! As a serious gamer I am certainly going to devote some time to this one. The idea is brilliant. Collaborative computing may bring breakthroughs that are decades away otherwise. If you pop this at least give the game a try :-)

POPSThe Hedonistic Imperative This manifesto outlines a strategy to eradicate suffering in all sentient life. The abolitionist project is ambitious, implausible, but technically feasible. It is defended here on ethical utilitarian grounds. Genetic engineering and nanotechnology allow Homo sapiens to discard the legacy-wetware of our evolutionary past. Our post-human successors will rewrite the vertebrate genome, redesign the global ecosystem, and abolish suffering throughout the living world.

POPSNano RNA Delivery Novel delivery agents could mean a more targeted way to turn off disease genes. The MIT researchers, however, developed a way to make more than a thousand different delivery agents in parallel using a simple, one-step chemical process. And that allowed the team to quickly discover effective delivery molecules, including several that surprised the researchers. "We wouldn't have necessarily sat down and said, this is a structure that's going to work," says Daniel Anderson, a research associate at the David H. Koch Institute for Integrative Cancer Research at MIT. "It was only by making and testing over a thousand that we were able to get to that place."

POPSIt's not immoral to want to be immortal the prospect of immortality raises complex ethical social and economical issues. This is exactly why we need immortality! So we will have unlimited time to resolve these very issues. If there is one thing humanity won't give up is the dream of immortality. It is as ancient as our race.
