A Gigantic Hole Just Opened Up in the Sun

Posted by in categories: particle physics, satellites

A massive hole opened up in the Sun’s atmosphere over the weekend, measuring more than 60 times the diameter of the Earth across at its peak.

Coronal holes like this one, imaged by NASA’s Solar Dynamics Observatory, occur when the Sun’s magnetic field suddenly allows a huge stream of the star’s upper atmosphere to pour out in the form of solar wind.

Over a short period of time, these highly energized particles can eventually make their way to us and — if powerful enough — wreak havoc on satellites in the Earth’s orbit. In rare instances, they can even mess with the electrical grid back on the ground.

IBM launches Quantum System Two and first 1,000+ qubit chip

Posted by in categories: computing, quantum physics

Computing giant IBM has launched three new innovations in quantum tech – the first utility-scale quantum computer, the first 1,000+ qubit chip and the most efficient quantum processor in terms of error correction.

IBM gave a sneak preview of its Quantum System Two during a conference last year. Following 12 months of additional research and development, it has now officially launched the system, which is described as “the first modular, utility-scale quantum computer.”

6 million-year-old ‘fossil groundwater pool’ discovered deep beneath Sicilian mountains

Posted by in category: futurism

A large pocket of fresh water that was sucked down into Earth’s crust 6 million years ago is still buried deep below a mountain range in Sicily, new research has found.

The fresh water likely became trapped underground during the Messinian salinity crisis, when the Mediterranean Sea dried up following a global cooling event that locked ocean water up in ice sheets and glaciers. This event likely exposed the seabed to rainwater that then trickled down into Earth’s crust, according to a study published Nov. 22 in the journal Communications Earth & Environment.

SpaceX sends up Space Coast’s 68th launch with Falcon Heavy on tap for weekend

Posted by in categories: internet, satellites

SpaceX knocked out yet another Falcon 9 launch overnight but is prepping for liftoff of its powerhouse Falcon Heavy from the Space Coast as early as Sunday.

A Falcon 9 lifted off from Cape Canaveral Space Force Station at 12:07 a.m. carrying another 23 Starlink satellites to orbit.

The first-stage booster flew for the ninth time with a recovery landing on the droneship Just Read the Instructions stationed downrange in the Atlantic.

Capella to use SpaceX for two Acadia satellite launches

Posted by in category: satellites

WASHINGTON — Capella Space will launch two radar imaging satellites on SpaceX rideshare missions after an Electron launch failure disrupted its deployment plans.

Capella announced Dec. 5 that it had arranged to fly two of its Acadia satellites on SpaceX rideshare missions in the first half of 2024. Acadia-4 will fly on the Bandwagon-1 mission as soon as April 2024 while Acadia-5 will launch on Transporter-11 no earlier than June 2024. The Transporter-11 mission was arranged through launch services company Exolaunch.

Capella said in a statement that the arrangements allow for a diversity of orbits for its spacecraft. Bandwagon-1 is the first of a new line of dedicated rideshare missions that SpaceX announced earlier this year that will go to mid-inclination orbits, rather than sun-synchronous orbits accessed by Transporter missions.

How cell identity is preserved when cells divide

Posted by in categories: biotech/medical, chemistry, genetics

An MIT study suggests 3D folding of the genome is key to cells’ ability to store and pass on “memories” of which genes they should express.


Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types in the body.

Each cell’s fate is largely determined by chemical modifications to the proteins that decorate its DNA; these modification in turn control which genes get turned on or off. When cells copy their DNA to divide, however, they lose half of these modifications, leaving the question: How do cells maintain the memory of what kind of cell they are supposed to be?
