Liver transplant breakthrough to halve the waiting list, say experts

Posted by in categories: biotech/medical, innovation

A machine which triples the time livers can survive outside the body promises to halve the transplant waiting list, experts have said as officials approved its use in the NHS.

Hundreds more patients with advanced liver disease — Britain’s fifth biggest killer — have hope of a successful transplant after the “game-changing” technique was given the green light by the National Institute of Health and Care Excellence (Nice).

Currently livers intended for transplant typically survive for only about eight to ten hours on ice.

New ultra-fast 3D printing technology uses resin and light

Posted by in category: 3D printing

Researchers with the University of Michigan have developed a new 3D printing technology that is capable of printing 100 times faster than normal 3D printers. Unlike traditional 3D printers, which work by applying plastic down as layers, the new technology involves resin that is solidified upward at rapid speeds. The new method is capable of producing complex objects at speeds that traditional printers can’t compete with.

Leaky blood-brain barrier identified as potential early-warning sign for Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

New research published in the journal Nature Medicine has described the results of a five-year study into the association between a breakdown of the blood-brain barrier and the onset of cognitive impairment. The study suggests leaky capillaries in the brain can act as an early biomarker of cognitive decline, and a new drug being developed for stroke patients may be an effective treatment.

Experiments detect entropy production in mesoscopic quantum systems

Posted by in categories: particle physics, quantum physics

The production of entropy, which means increasing the degree of disorder in a system, is an inexorable tendency in the macroscopic world owing to the second law of thermodynamics. This makes the processes described by classical physics irreversible and, by extension, imposes a direction on the flow of time. However, the tendency does not necessarily apply in the microscopic world, which is governed by quantum mechanics. The laws of quantum physics are reversible in time, so in the microscopic world, there is no preferential direction to the flow of phenomena.

One of the most important aims of contemporary scientific research is knowing exactly where the transition occurs from the quantum world to the classical world and why it occurs — in other words, finding out what makes the production of entropy predominate. This aim explains the current interest in studying mesoscopic systems, which are not as small as individual atoms but nevertheless display well-defined quantum behavior.

CERN Unveils Design for 62-Mile-Round Atom Smasher More Powerful Than the Large Hadron Collider

Posted by in categories: futurism, particle physics

A scientific collaboration has released a concept design for the Large Hadron Collider’s successor, an enormous new experiment that would sit inside a hundred-kilometer (62-mile) tunnel.

The design concept plans for two Future Circular Colliders, the first which would begin operation perhaps in 2040. The ambitious experiments would hunt for new particles with collision energies 10 times higher than those created by the Large Hadron Collider (LHC). The concept design is the first big milestone achieved by the scientific collaboration.

Researchers discover new evidence of superconductivity at near room temperature

Posted by in categories: computing, physics

Researchers at the George Washington University have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity.

Superconductivity is the lack of electrical resistance and is observed in many materials when they are cooled below a . Until now, superconducting materials were thought to have to cool to very low temperatures (minus 180 degrees Celsius or minus 292 degrees Fahrenheit), which limited their application. Since makes a system inefficient, eliminating some of this resistance by utilizing room temperature superconductors would allow for more efficient generation and use of electricity, enhanced energy transmission around the world and more powerful computing systems.

“Superconductivity is perhaps one of the last great frontiers of scientific discovery that can transcend to everyday technological applications,” Maddury Somayazulu, an associate research professor at the GW School of Engineering and Applied Science, said. “Room temperature has been the proverbial ‘holy grail’ waiting to be found, and achieving it—albeit at 2 million atmospheres—is a paradigm-changing moment in the history of science.”
