The Universe Is Expanding Faster Than We Thought, Hubble Data Suggests

  The Universe Is Expanding Faster Than We Thought, Hubble Data Suggests Recent Hubble Space Telescope findings suggest that the universe is expanding much faster than expected.Scientists use the Hubble Space Telescope to make precise measurements of the universe's expansion rate. However, observations for a new study don't match up with previous predictions based on the universe's trajectory following the Big Bang, according to a statement from the Space Telescope Science Institute (STScI).

"This can insulate better than most other current thermal insulators , including Styrofoam ," Tian Li, a researcher on the project, said in a statement. That turned the wood white and made it less able to conduct heat.

They're calling it nanowood and it insulates better than Styrofoam and silica aerogels. "This can insulate better than most other current thermal insulators, including Styrofoam," Tian Li, a researcher on the project, said in a statement. "It is extremely promising to be used as energy efficient building materials."

To make the material, the researchers took wood and stripped away two of its natural components -- lignin, which makes it brown and rigid, and hemicellulose. That turned the wood white and made it less able to conduct heat. The tubed structures within a tree that transport water and nutrients up the trunk run in one direction, and heat can conduct along those channels. But heat doesn't conduct across those channels very well and because stripping away the lignin and hemicellulose leaves a lot of gaps in the wood, wood treated to become nanowood conducts heat in that direction even less.

Krill's plastic digestion skills 'mind-blowing' for Australian scientists

  Krill's plastic digestion skills 'mind-blowing' for Australian scientists Krill in the Southern Ocean are able to break down plastic pollution, with a Griffith University study finding they are unknowingly ingesting micro-plastics and breaking them down into nano-plastics.The tiny crustaceans are ingesting micro-plastics unknowingly, and breaking them down into much smaller nano-plastics through their digestive system, research has found.

Along with insulating more effectively than currently used materials like Styrofoam, nanowood is also stronger, and it won't cause the same lung irritations that fibers from glass wool insulators do. The research team also says that it could be fabricated for as low as $7.44 per square meter, can be folded and rolled when less than one millimeter thick and is biodegradable, so it won't add to landfill waste like the insulating materials we often use now do.

"My research program experiments with nature's nanotechnology that we see in wood," project head Liangbing Hu, an associate professor in the department of materials science and engineering at the University of Maryland, said in a statement. "We are reinventing ways to use wood that could be useful in constructing energy efficient and environmentally friendly homes." The work was recently published in Science Advances.

‘Blood in my eyes’: Alleged home invasion victim's fear .
The victim of an alleged home invasion in Melbourne last week has spoken of the moment that he claims four young men smashed their way through his home. Security footage appears to reveal a brutal assault which began at 3am when Adam was asleep in bed."I did try to stand in the way to try and stop them, but because I was badly dazed from the first hit from the plank of wood ... I think that's when the blood started coming out so I had a fair bit of blood in my eyes," he said.The disability pensioner has an array of home security and footage he captured shows people allegedly ransacking his home and beating him.
