My 1.5KJ Home-Built Gauss Rifle!

I’ve finally finished my gauss rifle! This is about four months in the making. I may improve on it in the future, or build an entirely new and better one! But I want to take a break from coil guns for a while.

Disclaimer:
I’d consider myself to be a pacifist, and don’t intend to use this on any person or animal. This project has merely acted as an outlet for my interest in electronics and electromagnetism. My aim has also been to create something cool to get others interested in science and engineering.

Mark Zuckerberg has lost $70 billion in 2022 after metaverse leap

Markets have been down but Meta’s stock price loss is astounding.

Facebook founder Mark Zuckerberg’s personal worth has eroded by a whopping $71 billion dollars in 2022 alone, the most for any billionaire as tracked by Bloomberg.

IStock/COM & O

Last year, amidst the high scrutiny on the whistleblower complaints at Facebook, CEO Zuckerberg announced his company’s decision to focus on building the next big thing on the internet, the metaverse. This announcement was accompanied by a major rebranding of the company to Meta and a surge of interest in the metaverse.

Adobe’s $20 Billion Takeover Of Figma Makes Cofounders Billionaires

Dylan Field and Evan Wallace started building design startup Figma to challenge Adobe’s PhotoShop. Now Adobe has made them billionaires after announcing it would acquire Figma for $20 billion in a cash and shares deal.

The deal doubles the valuation that the San Francisco-based startup landed in June 2021, when it raised $200 million from investors including Durable Capital and Morgan Stanley. Forbes.

Figma has been branded the Google Docs, or GitHub, for designers with a loyal user base in the millions paying between $12 or $45 per editor for its digital whiteboard product.


The deal values Figma cofounders Dylan Field and Evan Wallace’s stakes in the buzzy design startup at $2 billion apiece.

Voices: Alarm bells are going off across the world — but we’re barely listening

Sometimes it’s easy to miss the forest for the trees. We spend so much time on what’s in front of us, we can miss the bigger picture. Alarm bells are going off across the world. We need to hear them.

An extreme heatwave and drought has been roasting China for 70 days straight, something that “has no parallel in modern record-keeping in China, or elsewhere around the world for that matter.”

Next door, in Pakistan, a “torrential downpour of biblical proportions” has so far killed 900 people and destroyed nearly 100,000 homes. Its neighbour India has suffered 200 heatwave days this year so far, compared to just 32 last year. South Korea received it’s the heaviest hourly downpour in Seoul for 80 years, flooding the capital and leaving 50 cities and towns with landslide warnings.

Brain folding

The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed by Wieland Huttner, director at the Max Planck Institute of Molecular Cell Biology and Genetics, now reports an important finding that paves the way for further research on brain evolution: The researchers analyzed the gyrencephaly index, indicating the degree of cortical folding, of 100 mammalian brains and identified a threshold value that separates mammalian species into two distinct groups: Those above the threshold have highly folded brains, whereas those below it have only slightly folded or unfolded brains. The research team also found that differences in cortical folding did not evolve linearly across species.

The Dresden researchers examined brain sections from more than 100 different with regard to the gyrencephaly index, which indicates the degree of folding of the neocortex. The data indicate that a highly folded neocortex is ancestral – the first mammals that appeared more than 200 million years ago had folded brains. Like brain size, the folding of the brain, too, has increased and decreased along the various mammalian lineages. Life-history traits seem to influence this: For instance, mammals with slightly folded or unfolded brains live in rather small social groups in narrow habitats, whereas those with highly folded brains form rather large social groups spreading across wide habitats.

A threshold value of the folding index at 1.5 separates mammalian species into two distinct groups: Dolphins and foxes, for example, are above this threshold value – their brains are highly folded and consist of several billion neurons. This is so because basal progenitors capable of symmetric proliferative divisions are present in the neurogenic program of these animals. In contrast, basal progenitors in mice and manatees lack this proliferative capacity and thus produce less neurons and less folded or unfolded brains.
