Pig brains partially revived after death

Posted by in categories: biotech/medical, neuroscience

US scientists have partially revived pig brains four hours after the animals were slaughtered.

The findings could fuel debate about the barrier between life and death, and provide a new way of researching diseases like Alzheimer’s.

The study showed the death of brain cells could be halted and that some connections in the brain were restored.

Magnonic devices can replace electronics without much noise

Posted by in categories: computing, particle physics

Electronic devices such as transistors are getting smaller and will soon hit the limits of conventional performance based on electrical currents.

Devices based on magnonic currents—quasi-particles associated with waves of magnetization, or , in certain —would transform the industry, though scientists need to better understand how to control them.

Engineers at the University of California, Riverside, have made an important step toward the development of practical magnonic devices by studying, for the first time, the level of noise associated with propagation of magnon current.

Researchers explore energy-saving catalysts that operate at room temperature

Posted by in categories: nanotechnology, particle physics

NIST researchers have explored in unprecedented detail a new breed of catalysts that allow some chemical reactions, which normally require high heat, to proceed at room temperature. The energy-saving catalysts use sunlight or another light source to excite localized surface plasmons (LSPs)—oscillations of groups of electrons on the surface of certain metal nanoparticles, such as gold, silver and aluminum. The energy derived from the LSP oscillations drives chemical reactions among molecules that adhere to the nanoparticles.

Scientists had previously shown that can be split into its individual atoms by the energy generated by the LSP oscillations. The NIST team has now discovered a second LSP-mediated reaction that proceeds at room temperature. In this reaction, LSPs excited in gold nanoparticles transform two molecules of carbon monoxide into carbon and carbon dioxide. The reaction, which ordinarily requires a minimum temperature of 400 degrees C., plays an important role in converting carbon monoxide into widely used carbon-based materials such as carbon nanotubes and graphite.

Probing the nanoparticles with an and combining the data with simulations, the NIST researchers pinpointed the sites on the gold nanoparticles where the reactions occurred. They also measured the intensity of the LSPs and mapped how the energy associated with the oscillations varied from place to place inside the nanoparticles. The measurements are key steps in understanding the role of LSPs for initiating reactions at room temperature, mitigating the need to heat the samples.

Researchers Just Demonstrated Nuclear Fusion in a Device Small Enough to Keep at Home

Posted by in category: nuclear energy

When it comes to the kinds of technology needed to contain a sun, there are currently just two horses in the race. Neither is what you’d call ‘petite’.

An earlier form of fusion technology that barely made it out of the starting blocks has just overcome a serious hurdle. It’s got a long way to catch up, but given its potential cost and versatility, a table-sized fusion device like this is worth watching out for.

While many have long given up on an early form of plasma confinement called the Z-pinch as a feasible way to generate power, researchers at the University of Washington in the US have continued to look for a way to overcome its shortcomings.

Discovery of oral cancer biomarkers could save thousands of lives

Posted by in categories: biotech/medical, genetics

Oral cancer is known for its high mortality rate in developing countries, but an international team of scientists hope its latest discovery will change that.

Researchers from the University of Otago and the Indian Statistical Institute (ISI), Kolkata, have discovered epigenetic markers that are distinctly different in tissues compared to the adjacent healthy tissues in patients.

Co-author Dr. Aniruddha Chatterjee, of Otago’s Department of Pathology, says finding these biomarkers is strongly associated with patient survival.

Mars in the Gobi Desert

Posted by in categories: education, space

In the desert hills of China’s Gansu province, a company called C-Space has just opened “Mars Base 1,” a simulated Martian base of operations for future astronauts. Plans for the base, currently an educational facility, include expansion—becoming more of a tourist destination soon, adding a space-themed hotel and restaurant. Photographers were on hand as some of the first student groups arrived to tour this vision of Mars in the China’s Gobi desert.
