Tractor Beam Created

OK, it only pulls 1cm objects and wouldn’t work in space, but still… Physics – A Macroscopic Tractor Beam with Acoustic Waves.

Gunshot victims to be suspended by replacing their blood

Doctors in UPMC Presbyterian Hospital in Pittsburgh, Pennsylvania are now waiting for a patient to show up with a gaping chest wound, who’s lost around 50% of his / her blood so they can replace the entire blood supply with a cold saline solution, which rapidly cools the body and stops almost all cellular activity.

First man/machine nerve grafts restore amputee’s sense of touch

After years of research and hours of gruelling surgery, scientists have successfully attached sensors from a prosthetic hand to human nerve tissue to allow the device to give its wearer a sense of touch. via First man/machine nerve grafts restore amputee's sense of touch • The Register.

Algae to crude oil: Million-year natural process takes minutes in the lab

In the PNNL process, a slurry of wet algae is pumped into the front end of a chemical reactor. Once the system is up and running, out comes crude oil in less than an hour, along with water and a byproduct stream of material containing phosphorus that can be recycled to grow more algae. http://phys.org/news/2013-12-algae-crude-oil-million-year-natural.html

Simulations back up theory that Universe is a hologram – and it seems that wormholes can be created using entanglement

A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate […]

evidence of transgenerational epigenetic inheritance: ‘Memories’ pass between generations

Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations. A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their “grandchildren”. The animals were trained to fear a smell similar to cherry blossom. The team at the […]

Wireless Device Converts “Lost” Energy such as WiFi signals into Electric Power

Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device, […]

Volume of nuclear waste could be reduced by 90 per cent says new research

Engineers from the University of Sheffield have developed a way to significantly reduce the volume of some higher activity wastes, which will reduce the cost of interim storage and final disposal. The researchers, from the University’s Faculty of Engineering, have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces […]

Microbe computers – Biological computers in living cells

This biological microcomputer sprang from the mind of Drew Endy, PhD, an assistant professor of bioengineering at Stanford. In three scientific papers released over a 13-month span in 2012 and 2013, Endy and a team of researchers from his lab showed how they used ordinary genetic engineering techniques to turn the bacterium E. coli — […]

When does a physical system compute?

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 […]

SPRITE found to be best cure for hangover

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, […]

Turning plastic bags into carbon nanotubes

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.

Particle accelerator on a chip

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'.

Beyond light speed – possible in theory using special relativity

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 […]

DNA has a 521-year half-life – so no cloning dinosaurs

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 […]

Alchemy! Superman-strength bacteria produce 24-karat gold

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 […]

Sharp’s semitransparent black solar panels

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 […]

MIT Develops a Way to agnetically Separate Oil From Water

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 […]

New software helps reveal patterns in space and time

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 […]

Gravitational waves spotted from white-dwarf pair

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.
