Thus, engineered wood has emerged as a sustainable and environmentally friendly alternative to traditional building materials. However, this wood is prone to warping and deterioration of structural integrity, diminishing its life span.
BepiColombo will be only the second mission in history to orbit Mercury, the scorched rocky planet close to the sun.
How the Big Bang gave us time, explained by theoretical physicist Sean Carroll.
Up next, The Universe in 90 minutes: Time, free will, God, & more ► https://youtu.be/tM4sLmt1Ui8
In this Big Think interview, theoretical physicist Sean Carroll discusses the concept of time and the mysteries surrounding its properties. He notes that while we use the word “time” frequently in everyday language, the real puzzles arise when we consider the properties of time, such as the past, present, and future, and the fact that we can affect the future but not the past.
Carroll also discusses the concept of entropy, which is a measure of how disorganized or random a system is, and the second law of thermodynamics, which states that there is a natural tendency for things in the universe to go from a state of low entropy to high entropy. He explains that the arrow of time, or the perceived difference between the past and the future, arises due to the influence of the Big Bang and the fact that the universe began in a state of low entropy.
Tesla Cybertruck sightings are continuing, and a video of the all-electric pickup released today gives a much better look at the vehicle’s air suspension.
Last night, a video of the Cybertruck rolling around Gigafactory Texas was shared, showing off its air suspension at what people said was its maximum ride height. However, it was very unclear and grainy, so it didn’t necessarily give a great look at what the Cybertruck will look like when utilizing its air suspension.
Now, a new video has been shared, where the Cybertruck appears to be, once again, at its maximum ride height, thanks to its air suspension, but the clearer resolution gives us a much more revealing look at the beast in its rarest form.

Permissions management is the essence of data security. Yet few security teams can manage identities in the cloud at scale, with Gartner estimating that by 2023, 75% of cloud security failures will occur due to insufficient management of identities, access and privileges.
However, more and more providers are looking to address permissions management with automation. Entitle, which today announced it has raised $15 million as part of a seed funding round led by Glilot Capital Partners, offers a platform for automating access management and provisioning.

Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe.
“These objects are way more massive than anyone expected,” said Joel Leja, assistant professor of astronomy and astrophysics at Penn State, who modeled light from these galaxies. “We expected only to find tiny, young, baby galaxies at this point in time, but we’ve discovered galaxies as mature as our own in what was previously understood to be the dawn of the universe.”
Using the first dataset released from NASA’s James Webb Space Telescope, the international team of scientists discovered objects as mature as the Milky Way when the universe was only 3% of its current age, about 500–700 million years after the Big Bang. The telescope is equipped with infrared-sensing instruments capable of detecting light that was emitted by the most ancient stars and galaxies. Essentially, the telescope allows scientists to see back in time roughly 13.5 billion years, near the beginning of the universe as we know it, Leja explained.
Arctic and save Greenland’s glaciers.
George Soros proposes geoengineering project to save Greenland’s glaciers.
Less problematic geoengineering already is underway with CO2 direct air capture. But more controversial sunlight blocking is being proposed.

The measurements from ancient and dormant galaxies show black holes growing more than expected, aligning with a phenomenon predicted in Einstein’s theory of gravity. The result potentially means nothing new has to be added to our picture of the Universe to account for dark energy: black holes combined with Einstein’s gravity are the source.
