I’ve been shocked sometimes when I walk in and see the patients. Most of the ones I’ve intubated are young — 30s, 40s, 50s. These are people who walked into the ER because they were coughing a day or two ago, or sometimes hours ago. By the time I come into the room, they are in severe respiratory distress. Their oxygen level might be 70 or 80 percent instead of 100, which is alarming. They are taking 40 breaths a minute when they should be taking 12 or 14. They have no oxygen reserves. They are pale and exhausted. It puts them in a mental fog, and sometimes they don’t hear me when I introduce myself. Some are panicky and gasping. Others are mumbling or incoherent. Last week, one patient was crying and asking to use my phone so they could call family and say goodbye, but their oxygen levels were dropping, and we didn’t have time, and I couldn’t risk bringing my phone in and contaminating it with virus, and the whole thing was impossible. I kept apologizing. I just —. I don’t know. I have to find a way to hold it together in order to do this job. I tear up sometimes, and if I do, it can fog up my face shield.

Researchers at Osaka University studied a new approach for laser nuclear fusion utilizing relativistic phenomena of intense laser light. By irradiating the ultra-intense laser light directly onto the fusion fuel, the researchers examined signs of heating of fusion fuel. This work may lead to widespread, clean fusion power.

Three decades and $23.7 billion later, the 25,000-ton International Thermonuclear Experimental Reactor is close to becoming something like the sun.

The ubiquitous particles are helping to map the innards of pyramids and volcanoes, and spot missing nuclear waste.

Kilopower is a small, light-weight fission nuclear power system capable of providing up to 10 kilowatts of electrical power — enough to run several average households continuously for at least 10 years.

Four Kilopower units would provide enough power to establish an outpost on the Moon or Mars.

Fusion research began in earnest in the 1960s, when scientists developed mirror machines. These linear tubes have pinched magnetic field lines on either end that act like mirrors, reflecting the charged plasma particles inward and retaining them and their heat in the machine. American researchers halted mirror research three decades ago, mainly due to an inability to contain the plasma.

WHAM will essentially take the team’s research back to the mirror machine days, but with significant upgrades.

“We hope to go well beyond what was done in the mirror program because we have access to very-high-field superconducting magnets like those being built by our partners for toroidal (donut-shaped) plasmas,” Forest says. “These magnets and heating systems simply weren’t available 20 years ago. It’s a new look at an older concept using new technology.”

WASHINGTON, D.C. — The U.S. Department of Energy today announced the winners of $32 million in funding for 15 projects as part of the Breakthroughs Enabling THermonuclear-fusion Energy (BETHE) program. These projects will work to develop timely, commercially viable fusion energy, with the goal to increase the number and performance levels of lower-cost fusion concepts.

“Fusion energy technology holds great potential to be a safe, clean, reliable energy source, but research and development of fusion technology is often constrained by prohibitive costs,” said Under Secretary of Energy Mark W. Menezes. “BETHE teams will build on recent progress in fusion research and the growing fusion community to lower costs and further foster viable commercial opportunities for the next generation of fusion technology.”

“These BETHE projects further advance ARPA-E’s commitment to the development of fusion energy as a cost-competitive, viable, energy generation source,” said ARPA-E Director Lane Genatowski. “Commercially viable fusion energy can improve our chances of meeting global energy demand and will further establish U.S. technological lead in this crucial area.”

Swapping out spent uranium rods requires hundreds of technicians—challenging right now.

Circa 2009 could used for a new fusion reactor using only a magnet.

Physicist Stewart E. Barnes and his collaborators at the Universities of Tokyo and Tohoku, Japan, have created a device that can store energy in nanomagnets.
