on the quantum gravity wormhole

Almost all of the initial descriptions were wrong or poorly written.  Now it appears that the experiment may have been wrong in the first place.  

Science is doing its job

 

 

 

 

omicron and long covid

Chances of having Covid turn into Long Covid are lower with Omicron.  Semi good news as there's still a chance and so many people have given up on precautions.

From today's IPCC report on climate change.  All alarms - action needs to be taken now.  Here's the low hanging fruit.  A carbon "tax" of $50 to $100 would be powerful.

polystyrene worked

I would not have guessed this would work - a novel technique for probing the proton's structure with neutrinos.

To measure the proton structure with high precision, scientists ideally would send neutrinos or antineutrinos into a very dense target made only of hydrogen, which contains protons but no neutrons. That is experimentally challenging, if not impossible to achieve. Instead, the MINERvA detector contains hydrogen that is closely bonded to carbon in the form of a plastic called polystyrene. But no one had ever tried to separate hydrogen data from carbon data.

“If we were not optimists, we would say it’s impossible,” says Tejin Cai, a postdoctoral researcher at York University and lead author on the Nature paper. Cai performed this research for his doctorate at the University of Rochester.

“The hydrogen and carbon are chemically bonded together, so the detector sees interactions on both at once. But then, I realized that the very nuclear effects that made scattering on carbon complicated also allowed us to select hydrogen and would allow us to subtract off the carbon interactions.”

freddy

The longest lived tropical storm on record.

Freddy’s longevity appears to be matched by its sheer relentlessness. “How much energy a storm churns through is calculated through a metric known as ACE, or Accumulated Cyclone Energy,” Cappucci explained. “It reflects both a storm’s intensity and duration. Storms harvest such energy from warm ocean waters and expend it through their winds and by generating precipitation.”

He added: “As of Saturday evening, Freddy had tallied somewhere in the neighborhood of 86 ACE units, surpassing the record of 85.26 set by hurricane and typhoon Ioke in August to September 2006. That’s more ACE than 100 of the past 172 Atlantic hurricane seasons — not individual storms, but entire seasons’ worth of ACE.”
