Last night, #ParkerSolarProbe surpassed 153,454 miles per hour becoming fastest-ever human-made object relative to the Sun
Posted by Michael Lance in category: space travel
This breaks the record set by the German-American Helios 2 mission in April 1976. The spacecraft will continue to break its own records, achieving a top speed of about 430,000 miles per hour in 2024. Catch up: https://go.nasa.gov/2qjOraI

DeepMind’s Eerie Reimagination of the Animal Kingdom
Posted by Shailesh Prasad in categories: futurism, robotics/AI
If a recent project using Google’s DeepMind were a recipe, you would take a pair of AI systems, images of animals, and a whole lot of computing power. Mix it all together, and you’ d get a series of imagined animals dream ed up by one of the AIs. A look through the research paper about the project—or this open Google Folder of images it produced—will likely lead you to agree that the results are a mix of impressive and downright eerie.
But t he eerie factor doesn’t mean the project shouldn’t be considered a success and a step forward for future uses of AI.

This Bizarre Form of Ice Grows at Over 1,000 mph, And Now Physicists Know How
Posted by Saúl Morales Rodriguéz in categories: mathematics, physics
New research into a very weird type of ice known as Ice VII has revealed how it can form at speeds over 1,000 miles per hour (1,610 kilometres per hour), and how it might be able to spread across yet-to-be-explored alien worlds.
This ice type was only discovered occurring naturally in March, trapped inside diamonds deep underground, and this latest study looks in detail at how exactly it takes shape – apparently in a way that’s completely different to how water usually freezes into ice.
Based on a mathematical model devised by researchers from the Lawrence Livermore National Laboratory in California, there’s a certain pressure threshold across which Ice VII will spread with lightning speed. This process of near-instantaneous transformation is known as homogeneous nucleation.

Studies raise questions over how epigenetic information is inherited
Posted by Xavier Rosseel in categories: biotech/medical, genetics, health
Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children — and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called ‘epigenetic inheritance’ — patterns of chemical ‘marks’ on or around our DNA that are hypothesised to be passed down the generations. But new research from the University of Cambridge suggests that this mechanism of non-genetic inheritance is likely to be very rare.
A second study, also from Cambridge, suggests, however, that one way that environmental effects are passed on may in fact be through molecules produced from the DNA known as RNA that are found in a father’s sperm.
The mechanism by which we inherit innate characteristics from our parents is well understood: we inherit half of our genes from our mother and half from our father. However, the mechanism whereby a ‘memory’ of the parent’s environment and behaviour might be passed down through the generations is not understood.
