Computing is a high-level process of a physical system. Recent interest in non-standard computing systems, including quantum and biological computers, has brought this physical basis of computing to the forefront. There has been, however, no consensus on how to tell if a given physical system is acting as a computer or not; leading to confusion Read more about When does a physical system compute?[…]
Chinese scientists examined 57 drinks – from herbal teas to fizzy drinks. Found that some helped to speed up the process where the body breaks down alcohol, helping relieve a hangover quicker. But some slowed the process down, meaning symptoms remained Young people – and regular drinkers – produce more of the alcohol dehydrogenase enzyme, Read more about SPRITE found to be best cure for hangover[…]
University of Adelaide researchers have developed a process for turning waste plastic bags into a high-tech nanomaterial. […] The process is also catalyst and solvent free, which means the plastic waste can be used without generating poisonous compounds. via Turning plastic bags into high-tech materials.
In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice. via SLAC National Accelerator Laboratory – Researchers Demonstrate 'Accelerator on a Chip'.

University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light. Einstein’s theory holds that nothing could move faster than the speed of light, but Professor Jim Hill and Dr Barry Cox in the University’s School of Mathematical Sciences have developed new formulas that allow for travel Read more about Beyond light speed – possible in theory using special relativity[…]
By comparing the specimens’ ages and degrees of DNA degradation, the researchers calculated that DNA has a half-life of 521 years. That means that after 521 years, half of the bonds between nucleotides in the backbone of a sample would have broken; after another 521 years half of the remaining bonds would have gone; and Read more about DNA has a 521-year half-life – so no cloning dinosaurs[…]
the metal-tolerant bacteria Cupriavidus metallidurans can grow on massive concentrations of gold chloride — or liquid gold, a toxic chemical compound found in nature. Brown and Kashefi fed the bacteria unprecedented amounts of gold chloride, mimicking the process they believe happens in nature. In about a week, the bacteria transformed the toxins and produced a Read more about Alchemy! Superman-strength bacteria produce 24-karat gold[…]
The panels are laminated glass infused with photovoltaic cells. Each panel contains rows of cells arranged so that natural light can shine through. The new product is said to deliver a solar power conversion efficiency of about 6.8-percent with a maximum output of 95 watts. The module can also act as a heat shield, preventing Read more about Sharp’s semitransparent black solar panels[…]
During their research, they used water-repellent ferrous nanoparticles mixed in with the oil, in order to separate it later with magnets. The amazing part is that once the nanoparticles are magnetically removed from the oil, they can then be reused. via MIT Develops a Way to Magnetically Separate Oil From Water | Inhabitat – Sustainable Read more about MIT Develops a Way to agnetically Separate Oil From Water[…]
The GeoDa Center for Geographical Analysis & Computation, led by ASU Regents’ Professor Luc Anselin, has just released a new version of its signature software, OpenGeoDa. The software provides a user-friendly interface to implement techniques for exploratory spatial data analysis and spatial modeling. It has been used to better understand issues ranging from health care Read more about New software helps reveal patterns in space and time[…]
Two dwarf stars – oribiting each other every 13 minutes – have been observed to slightly change the size of their orbits as well as the time it takes to complete them. The effect occurs when expected to happen as they hit the waves. BBC News – Gravitational waves spotted from white-dwarf pair.

BAE systems has developed a system based on radio frequency systems to position itself. It’s a learning system that uses GPS to track it’s own location whilst reading the unique RF signals strength and ID. One Per Cent: TV and radio signals take over when GPS goes wrong.
Through a process involving thin layers of material deposited on a surface and then selectively etched away, the MIT team produced a surface covered with tiny cones, each five times taller than their width. This pattern prevents reflections, while at the same time repelling water from the surface via Researchers find a way to make Read more about Researchers find a way to make glass that’s anti-fogging, self-cleaning and free of glare[…]
Feeding rats bucky balls (Buckminster Fullerine) resulted in a doubling of the lifespan for rats.

Life is an inordinately complex unsolved puzzle. Despite significant theoretical progress, experimental anomalies, paradoxes, and enigmas have revealed paradigmatic limitations. Thus, the advancement of scientific understanding requires new models that resolve fundamental problems. Here, I present a theoretical framework that economically fits evidence accumulated from examinations of life. This theory is based upon a straightforward Read more about Theory of the Origin, Evolution, and Nature of Life[…]
