How science could help cyclists to keep pedalling for longer

Posted by in categories: energy, food, military, science

Nice.


Elite endurance athletes could be able to keep going for longer thanks to a new drink developed to give soldiers extra energy in battle, a study using former Olympians has found.

Scientists found that cyclists using the drink, which temporarily switches the body’s energy source from glucose to ketones, could travel an extra quarter of a mile than those taking a different energy supplement.

U.S. wary on biotech advances; gene editing, CRISPR ‘raising urgency’

Posted by in categories: bioengineering, biotech/medical, ethics

Hmmm.


We can rebuild him; we have the technology—but Americans question if we should in a new survey designed to assess attitudes to modern biotechnology advances.

A new report, based on a survey of 4,700 U.S. adults coming out of the Pew Research Center, looked at a range of views on certain advances in biology, with opinions split on the ethics and long-term problems associated with enhancing human capacity.

Getting light in shape with metamaterials

Posted by in categories: nanotechnology, quantum physics, supercomputing

A team built a specialized, layered structure with tiny metallic cavities that improves the light conversion efficiency by orders of magnitude.

Artist’s rendering of an incident laser beam (top of the figure) illuminating an array of nanoscale gold resonators on the surface of a “quantum well” semiconductor (slab in figure). (A quantum well is a thin layer that can restrict the movement of electrons to that layer.) The incoming laser beam interacts with the array and the quantum wells and is converted into two new laser beams with different wavelengths. Changing the size, shape, and arrangement of the resonators can be used for beam focusing, beam steering, or control of the beam’s angular momentum. (Image: Sandia National Laboratories)

Improving computer graphics with quantum mechanics

Posted by in categories: computing, engineering, quantum physics

Nice article; I do need to mention that more and more screen displays are moving to Q-Dot technology. So, computer graphics is being enriched in multiple ways by Quantum.


Caltech applied scientists have developed a new way to simulate large-scale motion numerically using the mathematics that govern the universe at the quantum level.

The , presented at the International Conference and Exhibition on Computer Graphics & Interactive Techniques (SIGGRAPH), held in Anaheim, California, from July 24–28, allows computers to more accurately simulate vorticity, the spinning motion of a flowing fluid.

Moving beyond semiconductors for next-generation electric switches

Posted by in categories: energy, mathematics, mobile phones, quantum physics, supercomputing

Computers use switches to perform calculations. A complex film with “quantum wells”—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first time, this oxide film exhibited a phenomenon, called resonant tunneling, in which electrons move between quantum wells at a specific voltage. This behavior allowed an extremely large ratio (about 100,000:1) between two states, which can be used in an electronic device as an ON/OFF switch to perform mathematical calculations (Nature Communications, “Resonant tunneling in a quantum oxide superlattice”).

Quantum wells

Efficient control of electron motion can be used to reduce the power requirements of computers. “Quantum wells” (QW) are regions that allow electron motion in only two dimensions. The lines (bottom) in the schematic show the probability of finding electrons in the structure. The structure is a complex oxide (top) with columns (stacked blue dots corresponding to an added element) where the electrons are free to move in only two dimensions. This is a special type of quantum well called a two-dimensional electron gas (2DEG). (Image: Ho Nyung Lee, Oak Ridge National Laboratory)
