The Nuclear Reactor Renaissance: Space Exploration and National Security

Posted by in categories: climatology, nuclear energy, security, solar power, space travel, sustainability

The nuclear power sector is seeing a resurgence in innovation, supported by new policies and emerging technologies. The general public and various governments are starting to grasp the value of nuclear power as an alternative, sustainable energy source. Unlike renewables, such as wind and solar power, nuclear energy is not dependent on weather conditions for power generation, having a capacity factor of over 90 percent. Nuclear power is also more eco-friendly than natural gas and coal and its “carbon-free” attributes are seen as critical in the fight against climate change.

For decades, advancements in the nuclear power sector have been incremental and focused largely on making systems “walk away safe.” Today, the industry is pushing the boundaries and exploring applications for nuclear power in ways that have never before been considered.

BWXT is at the forefront of this nuclear renaissance. This 6,000-employee company operates on the model of letting capital drive strategy. BWXT is constantly evaluating new ways to ensure workers, funding, and policies are utilized in the most effective way possible. The company also analyzes the needs of numerous other industries to determine how nuclear power could provide innovative solutions.

The AI revolution has spawned a new chips arms race

Posted by in category: robotics/AI

There’s no x86 in the AI chip market yet—” People see a gold rush; there’s no doubt.”

A lot has changed since 1918. But whether it’s a literal (like the City of London School athletics’ U12 event) or figurative (AI chip development) race, participants still very much want to win.

For years, the semiconductor world seemed to have settled into a quiet balance: Intel vanquished virtually all of the RISC processors in the server world, save IBM’s POWER line. Elsewhere AMD had self-destructed, making it pretty much an x86 world. And Nvidia, a late starter in the GPU space, previously mowed down all of it many competitors in the 1990s. Suddenly only ATI, now a part of AMD, remained. It boasted just half of Nvidia’s prior market share.

Drug boosts immune system in elderly people

Posted by in categories: biotech/medical, life extension

Drugs were created to block a protein called the mammalian target of rapamycin (mTOR) and it boosted the immune system by about 40% in elderly people.

They safely reducing infections in elderly volunteers around 40% by enhancing the immune system.

In 2004, tests that blocked a similar enzyme in fruit flies gave them a longer lifespan.

Room temperature superconductivity evidence with graphene in contact with alkanes

Posted by in category: materials

Arxiv – Observation of the Meissner effect at room temperature in single-layer graphene brought into contact with alkanes

There are claims of synthesis of a room temperature superconductor. However, these claims have not been officially accepted by scientific communities. Currently, the highest transition temperature (Tc) recognized in scientific articles is 135 K at 1 atm of Hg-Ba-Ca-Cu-O system which is a copper oxide superconductor. We packed graphite flakes into a ring-shaped polytetrafluoroethylene (PTFE) tube and further injected heptane or octane. Then we generated circulating current in this ring tube by electromagnetic induction and showed that this circulating current continues to flow continuously at room temperature for 50 days. This experiment suggests that bringing alkane into contact with graphite may result in a material with zero resistance at room temperature.

Wall Street’s Big Banks Are Waging an All-Out Technological Arms Race

Posted by in category: finance

But constraints brought about by the financial crisis ended the leverage that had fueled the boom. Fixed-income traders felt the brunt of the changes, and in the years since, equities traders —especially those with a technology background—have enjoyed a renaissance. Their rise has touched off a battle for supremacy that’s come down to only three companies: Goldman Sachs, Morgan Stanley, and JPMorgan Chase. These rivals are now locked in a technological arms race to control a $58 billion-a-year industry. As they each jockey for an edge over the other, no one who trades on Wall Street is safe.


Dimon, Blankfein, Gorman: Three great rivals are battling to control the $58 billion-a-year equities industry.

Method of making oxygen from water in zero gravity raises hope for long-distance space travel

Posted by in categories: nanotechnology, space travel

In the new study, the researchers dropped the full experimental set up for photocatalysis down a 120m drop tower, creating an environment similar to microgravity. As objects accelerate towards Earth in free fall, the effect of gravity diminishes as forces exerted by gravity are cancelled out by equal and opposite forces due to the acceleration. This is opposite to the G forces experienced by astronauts and fighter pilots as they accelerate in their aircraft.

The researchers managed to show that it is indeed possible to split water in this environment. However, as water is split to create gas, bubbles form. Getting rid of bubbles from the catalyst material once formed is important – bubbles hinder the process of creating gas. On Earth, gravity makes the bubbles automatically float to the surface (the water near the surface is denser than the bubbles, which makes them buyonant) – freeing the space on the catalyst for the next bubble to be produced.

In zero gravity this is not possible and the bubble will remain on or near the catalyst. However, the scientists adjusted the shape of nanoscale features in the catalyst by creating pyramid-shaped zones where the bubble could easily disengage from the tip and float off into the medium.
