Researchers ‘reboot’ pig brains hours after animals died
Posted by Shailesh Prasad in categories: biotech/medical, neuroscience
The brains of decapitated pigs can be partially revived several hours after the animal has died, researchers have revealed, with some of the functions of cells booted back up when an oxygen-rich fluid is circulated through the organ.
The scientists stress that the brains do not show any signs of consciousness – for example, there was no sign that different parts of the brain were sending signals to each other – and that it does not change the definition of death.
But they say they have found a way to prevent brain cells from sustaining irreparable damage as blood stops circulating, and even to restore some of the cells’ functions.

Lightning Totally Does Strike Twice, And Now Scientists Know Why
Posted by Shailesh Prasad in categories: climatology, physics
There’s something about the meandering streak of lightning that implies random chaos. Yet bolts from the blue not only hit the same places with regularity, but successive discharges often reuse the exact same channel.
It’s never been entirely clear how the path laid down by one bolt sticks around for repeat performances, but new research has discovered lingering pockets of charge in the wake of a single lightning strike, which could provide a map for more to follow.

Scientists invent way to trap mysterious ‘dark world’ particle at Large Hadron Collider
Posted by Quinn Sena in categories: cosmology, particle physics
Now that they’ve identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target.
All around us is dark matter and dark energy—the invisible stuff that binds the galaxy together, but which no one has been able to directly detect. “We know for sure there’s a dark world, and there’s more energy in it than there is in ours,” said LianTao Wang, a University of Chicago professor of physics who studies how to find signals in large particle accelerators like the LHC.
Wang, along with scientists from the University and UChicago-affiliated Fermilab, think they may be able to lead us to its tracks; in a paper published April 3 in Physical Review Letters, they laid out an innovative method for stalking dark matter in the LHC by exploiting a potential particle’s slightly slower speed.

This could be the biggest advance in toilet design in over a hundred years
Posted by Quinn Sena in category: futurism
The Orca Helix moves up and down so that it is easy to get on and off when high, easy on the body when low.
Many things have changed in the last hundred years, but one thing that has hardly changed at all is the toilet. And as we have been saying on TreeHugger for what feels like a hundred years, it’s all wrong. Our bodies are designed to squat, yet instead, we sit on 14 inch high seats, which actually makes it hard to poop. As we get older, or fatter, people have trouble even getting on a 14 inch seat and buy “comfort height” toilets, which make it even harder to poop. It is exactly the wrong thing to do, causing constipation, haemorrhoids and worse.

It’s official: Blue Origin will bring rocket engine tests back to Huntsville
Posted by Genevieve Klien in categories: security, space travel
One of Huntsville’s historic Apollo engine test stands is coming back to life under an agreement between NASA and Jeff Bezos’ Blue Origin space company.
NASA announced Wednesday it has signed an agreement to let Blue Origin use Marshall Test Stand 4670 to test its BE-3U and BE-4 rocket engines. The BE-4 has been selected to power United Launch Alliance’s new Vulcan rocket and Blue’s New Glenn rocket.
Both rockets are being built to power new boosters for America’s three key space markets: NASA, commercial companies like ULA and national security customers such as the Air Force.
