A 70-year-old man with a history of hypertension and chronic migraine presented with 10 months’ history of progressive generalized muscle weakness and stiffness. He reported a 19-kg unintentional weight loss over the last 7 months. He described worsening exertional dyspnea over the past 3 weeks prior to presentation. He had multiple surgical procedures for joint contractures and bilateral carpal tunnel syndrome in the past 5 years. He had no history of smoking or alcohol consumption. Physical examination revealed generalized muscle wasting except for hypertrophy of bilateral shoulder muscles (Figure 1 A) with proximal muscle weakness of the shoulders. The reflexes and sensation were intact in both upper limbs, and there was no distal weakness.

Researchers have discovered a way to protect quantum information from environmental disruptions, offering hope for more reliable future technologies.
In their study published in Nature Communications, the scientists have shown how certain quantum states can maintain their critical information even when disturbed by environmental noise. The team includes researchers from the University of the Witwatersrand in Johannesburg, South Africa (Wits University) in collaboration with Huzhou University in China.
“What we’ve found is that topology is a powerful resource for information encoding in the presence of noise,” says Professor Andrew Forbes from the Wits School of Physics.
In a crowded room, we naturally move slower than in an empty space. Surprisingly, worms can show the exact opposite behavior: In an environment with randomly scattered obstacles, they tend to move faster when there are more obstructions. Viewing the worms as “active, polymerlike matter,” researchers at the University of Amsterdam have now explained this surprising fact.
The research was published in Physical Review Letters this week, and was selected by the editors of that journal as an Editors’ Suggestion.
One way in which worms differ from humans is, of course, their shape: a worm’s length is much larger than its width (i.e., it is spaghetti-like), and moreover it is wiggly—or in more scientific terms: It behaves like an active polymer. The researchers suspected that this active, polymer-like behavior is what makes the worms behave in their counterintuitive way.
Scientists at RIKEN CEMS have discovered that twisting atomically thin layers in a device can precisely control superconductivity.
