If you find yourself moving, look ahead and then look behind. If it is a push, there will be more stuff behind us. if it is a pull, there will be more stuff in front of us. This is important because it is unlikely that any attractive forces are fundamental, which means all apparent attraction is simply a side-effect of repulsion. This discovery adds to the body of evidence supporting that idea. The next challenge is, we need to prove that gravity is not an attractive force but the side-effect of a more fundamental repulsive force.

I don't know how the reporter thinks this discovery could ever lead to cloning of such an organism. A typical eukaryote has 20,000 to 100,000 proteins in its proteome. Even viruses could have hundreds of proteins. To clone an organism, you will need to have a full copy of its DNA (or RNA in the case of RNA viruses). That means prestine samples of all proteins from the proteome. Even having that is not enough, since going from proteins to DNA is not straightforward -- since proteins are often modified after translation. Even then, you also need non-protein encoding DNA which is just as important for the survival of the organism.

I would say it is a pipe dream to start thinking of cloning, based on finding a fragment of a pre-historic protein. Rather than speculate about cloning, there are a lot of other very useful questions this discovery can answer, such as how that protein has evolved with respect similar proteins modern variants of the same species. We could perhaps then understand what micro-evolutionary pressures could have influenced (or not influenced) the evolution of a species such as an ostrich which has survived all these years.

Submission + - New AMD Zen APU boasts up to 16 cores (plus Greenland GPU with HBM) (

Hamsterdan writes: Greenland graphics HBM for Godaveri successor

We got an update on AMD's 2016 processor plans and the new APU with up to 16 Zen x86 cores and integrated Greenland HMB graphics is something that you may find interesting.

The new APU is expected to launch sometime in 2016, replacing the Godaveri platform that we all got to know as the Carrizo APU. Carrizo notebook APUs should launch at Computex, or early June 2015. The new Zen-core powered APU doesn't have a solid codename just yet, at least not the one that our sources are comfortable revealing.

The new APU platform has everything AMD fans could wish for — four channel DDR4 support, PCIe3, up to 16 Zen cores and Greenland GPU, paired with High Bandwidth Memory (HBM). The ability to add up to 16 Zen CPU cores suggests that AMD plans to use this chip for the compute market too, as the marriage of 16 Zen processors and HBM powered Greenland graphics can probably score some amazing compute performance numbers.

Yes, we think such an architecture is a perfect match for the Heterogeneous System Architecture (HSA). In case you are not familiar with this term, HSA is a type of computer processor architecture that integrates CPU and GPU on the same bus, with shared memory and tasks.

Submission + - We the people petition to revoke Scientology's Tax exempt status (

An anonymous reader writes: There has been a lot of interest in the activities of the Church of Scientology recently, especially since the release of Alex Gibney's documentary "Going Clear". A petition against tax-exempt status for Scientology, has been started on the United States white house petition website. If it receives more than 100,000 signatures, it will qualify for an official white house response. Even slashdot has had its own run-ins with Scientology in the past. Has the time come for Scientology go "clear"?

We've been seeing things like and many orders of magnitude more complex that this using Crystallography for more than a hundred years. Google "electron density maps" and check out some of the pictures in 3D. Then head over to the Protein Data Bank to see atomic resolution molecular structures determined using crystallography for more than 80,000 protein, nucleic acids (DNA, RNA) and carbohydrates. Even the Ribosome structure has been determined all in 3D. What they have here is a force map which is even more indirect than the electron density and these molecules are "nano-dwarfed" by the sheer complexity and size of molecules whose structures are already available by crystallography.
