Scientists May Have Figured Out Why Dead Brains Don't Always Rot

fahrbot-bot shares a report from Smithsonian Magazine: The brain is one of the first organs to begin decomposing after death. Yet archaeologists have discovered more than 4,400 preserved human brains around the world, some of which have remained intact for the last 12,000 years. In hundreds of cases, the brain was the only soft tissue left among otherwise skeletal remains. But how and why do brains sometimes persist for millennia while all other types of soft tissue disappear? This preservation paradox has stumped scientists for years. Now, however, a team of researchers say they may have solved the mystery. If a brain ends up in a wet, oxygen-starved environment, the processes that usually cause decay can have the opposite effect, researchers report in a study published in the August 7 issue of the Journal of Proteome Research. "Under the right conditions, preservation actually arises from decay itself: The same reactions that degrade tissue can also weld the breakdown products together into something far tougher," study co-author Alexandra Seviour, a paleobiologist at the University of Oxford in England, tells Live Science's Victoria Atkinson. Following experiments on 72 mouse carcasses (described in the article) the scientists think they know why. When oxygen is abundant, it triggers a cascading, chemical chain reaction that causes brain proteins to break down rapidly. This sequence hinges on free radicals, highly reactive, unstable molecules that "steal" electrons from nearby atoms and molecules. The process happens in the brains of living people too, and if left unchecked, can cause health problems. In low-oxygen environments, however, this chemical sequence appears to play out differently. The researchers' analyses hint that free radicals instead react and bond with nearby proteins, making the overall tissue tougher and more resistant to decomposition, Seviour tells Chemical and Engineering News' Anirban Mukhopadhyay. The findings show that "decay is not the opposite of preservation but, under specific chemical constraints, one of its mechanisms," the researchers write in the paper.

SpaceX Plans to Build a $100 Billion Spaceport In Louisiana

SpaceX plans to spend up to $100 billion building a new Starship launch facility in Vermilion Parish, Louisiana, which the state says could eventually "support thousands of launches annually." CNBC reports: Once built, Starbase, LA will serve as the main launch facility for Starship, SpaceX's in-development rocket that's the largest ever built and designed to be fully reusable. Musk has aspirations to massively expand SpaceX's Starlink satellite network, to launch orbital data centers and to someday colonize Mars. Those ambitions, and justification for SpaceX's nearly $2 trillion market cap, hinge on the success of Starship. SpaceX said, in a video posted to its website on Tuesday, that the search for a site to build launch pads and have access to ample fuel for its operations took about seven years. Musk said in the video that the company would bring "probably 10,000 really exciting jobs" to Louisiana with the spaceport. A fact sheet posted online by the state of Louisiana said SpaceX is expected to generate an estimated "3,000 direct new jobs over the next 10 years" in the state, and "8,100 indirect new jobs." SpaceX said it would work on a "historic coastal restoration" in Louisiana, in partnership with the state to "bring the marsh back" and ensure the wetlands around its new facility will have "storm protection."

Lab Supply Companies Have Been Selling Antibodies Using Manipulated Images

An anonymous reader quotes a report from Ars Technica: Antibodies play a central role in your body's immune defense. But they're also nearly ubiquitous in biological research, being essential for several widely used lab techniques. While some researchers need to go through the process of producing their own antibodies, antibodies to many key proteins are commercially available and can be ordered for overnight delivery. In May, however, Reese Richardson, a post-doc at Northwestern University, discovered that some of the images used to demonstrate how these antibodies performed in lab experiments had been subject to image manipulation -- the sorts of changes that would get a paper retracted if they had appeared in the academic literature. The manipulations ranged from removing background noise to copying and pasting data to fabricate results. Now, he has done a more exhaustive search and found problematic manipulations in images used to market over 17,000 commercial antibodies. [...] The consequences of this discovery are pretty significant. If you buy an antibody believing it will generate clean, clear data and find it doesn't, many researchers will assume the problem is them. That often leads them to spend time troubleshooting the procedure and trying slightly different conditions to get useful data. If the antibody can't produce those results, all the troubleshooting will have been a waste of time and money. Nature's coverage of the new findings includes quotes from several companies that sell these antibodies that, paraphrased, range from "we'll look into it" to "we don't think it's a problem." Researchers who have spent time frustrated while failing to get an antibody-based experiment to work may think otherwise.
