Improved prime editing system makes gene-sized edits in human cells at therapeutic levels

Posted by in categories: biotech/medical, genetics

“It’s exciting to see the high efficiency and versatility of eePASSIGE, which could enable a new category of genomic medicines,” added Gao. “We also hope that it will be a tool that scientists from across the research community can use to study basic biological questions.”

Prime improvements

Many scientists have used prime editing to efficiently install changes to DNA that are up to dozens of base pairs in length, sufficient to correct the vast majority of known pathogenic mutations. But introducing entire healthy genes, often thousands of base pairs long, in their native location in the genome has been a long-standing goal of the gene-editing field. Not only could this potentially treat many patients regardless of which mutation they have in a disease-causing gene, but it would also preserve the surrounding DNA sequences, which would increase the likelihood that the newly installed gene is properly regulated, rather than expressed too much, too little, or at the wrong time.

The universe is significantly older than previously thought

Posted by in category: cosmology

In a groundbreaking discovery, the James Webb Space Telescope (JWST) has presented data that directly challenges our current understanding of the universe. For years, cosmologists have pegged the universe’s age at approximately 13.8 billion years. Yet, the new JWST findings suggest that this may be a vast underestimation. But how has one telescope managed to disrupt such a long-held belief?

The universe’s secrets are vast, but none has been as puzzling as the presence of ‘impossible early galaxies’—so named due to their peculiar formation periods.

Company Awarded AFRL Contract to Investigate the Delivery of Five-to-Ten-Ton Capacity Containers Anywhere in the World in 90 Minutes

LOUISVILLE, Colo. – October 3, 2024Sierra Space, a leading commercial space company and defense-tech prime that is Building a Platform in Space to Benefit Life on Earth® and protect economic freedom in the Orbital Age®, announced today that it has been awarded a competitive, firm-fixed-price contract for the Rocket Experimentation for Global Agile Logistics (REGAL) program by Air Force Research Laboratory (AFRL). This new contract aims to revolutionize logistics and materiel returns from space, placing Sierra Space at the forefront of defense and space logistics innovation.

Earlier this year, the company unveiled its Sierra Space Ghost decelerator – a revolutionary logistics spacecraft designed for rapid payload return from Earth orbit – and shared the results of successful beta flight testing. The REGAL contract will support efforts to conceptually design and scale this new breakthrough technology, with the goal of landing critical supplies anywhere on the planet within 90 minutes.
