How does Xi Jinping’s ‘special plane’ compare with Air Force One?

Ahead of Chinese President Xi Jinping’s visit to Washington this week, attention is already turning to the aircraft that will carry him and how it stacks up against America’s famous presidential plane.

This discovery is why Einstein was history’s greatest physicist

Although many people struggle to name even one living scientist, practically everyone around the world knows who Einstein was. Perhaps the most famous person of the 20th century, Einstein revolutionized the sciences of physics and astronomy, making important contributions that taught us: the speed of light is the same for everyone, that energy and mass are equivalent, and related by the equation E = mc² , that light and electrons are both quantized into discrete “packets” of energy, and that space and time are not absolute and objective, among many other discoveries that are still relevant…

The Future Is Fanless: 100% Heat Capture for Liquid Cooled AI Servers

This article is brought to you by CoolIT, an Ecolab Company . Beyond 250 kW a server rack can no longer be cooled by a hybrid approach of liquid and air. At this density a 70/30 liquid-air split leaves 75 kW of air load. The air cooling system needed to move it brings cost and complexity few operators will accept. The answer is near-total heat capture. Liquid takes effectively all the heat, air falls below 1 percent of the load, allowing the server to run fanless. CoolIT builds these loops today from modular coldplate blocks proven across six generations of fanless designs. Processor thermal…

This emerging treatment could help people avoid knee replacement surgery

A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood vessels associated with inflammation, GAE can significantly reduce pain, with some patients reporting little or no pain afterward. Studies suggest the benefits may last two to four years in people who respond well.

[Series] Understanding peripheral arterial disease in the current era

Atherosclerotic cardiovascular disease is the primary driver of premature death in global populations in recent decades. Mortality statistics, most publications, and guidelines in the atherosclerotic cardiovascular disease field have traditionally focused on cardiac and cerebrovascular adverse events and causes of death. However, given the increasing prevalence of lower extremity peripheral arterial disease and its expanding burden on global health systems, such an emphasis might represent a skewed perception of vascular risk within the broader atherosclerotic spectrum.
