Your Standing Desk Might Actually Be as Bad as Sitting All Day

Posted by in category: biotech/medical

In recent years, standing has been touted as a remedy to a sedentary lifestyle, especially for desk workers who spend long hours seated at their screens.

But a new study from researchers in Australia and the Netherlands has found standing for long periods of time might not be much better than sitting after all – and actually comes with its own life-threatening risks.

Meta’s nuclear power plans were foiled by bees — yes, bees

Posted by in categories: nuclear energy, robotics/AI

A rare species of bee was found on land where the company was planning to put a nuclear-powered artificial intelligence data center, the Financial Times reported, citing people familiar with the matter. Meta CEO Mark Zuckerberg reportedly told employees during an all-hands meeting that the rare bees would further complicate a deal with an existing nuclear power plant to build the data center.

Sam Altman Says AGI Is “Achievable With Current Hardware”

Posted by in category: robotics/AI

Even the exact definition of AGI is still heavily debated, making it a murky milestone.

Regardless, the stakes are high: the AI industry has poured untold billions of dollars into building out datacenters to train AI models, an investment that’s likely many years away from paying off.

Naturally, OpenAI CEO and hypeman Sam Altman has remained optimistic. During a Reddit AMA this week, he even claimed that AGI is “achievable with current hardware.”

Japan-made world’s first wooden satellite blasts off into space

Posted by in categories: materials, satellites

The world’s first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.

LignoSat, developed by Kyoto University and homebuilder Sumitomo Forestry, will be flown to the International Space Station on a SpaceX mission, and later released into orbit about 400 kilometres above the Earth.

Named after the Latin word for “wood”, the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore living in space.

Coarse-Grained Simulations of Adeno-Associated Virus and Its Receptor Reveal Influences on Membrane Lipid Organization and Curvature

Posted by in categories: biotech/medical, virtual reality

Adeno-associated virus (AAV) is a well-known gene delivery tool with a wide range of applications, including as a vector for gene therapies. However, the molecular mechanism of its cell entry remains unknown. Here, we performed coarse-grained molecular dynamics simulations of the AAV serotype 2 (AAV2) capsid and the universal AAV receptor (AAVR) in a model plasma membrane environment. Our simulations show that binding of the AAV2 capsid to the membrane induces membrane curvature, along with the recruitment and clustering of GM3 lipids around the AAV2 capsid. We also found that the AAVR binds to the AAV2 capsid at the VR-I loops using its PKD2 and PKD3 domains, whose binding poses differs from previous structural studies. These first molecular-level insights into AAV2 membrane interactions suggest a complex process during the initial phase of AAV2 capsid internalization.
