Newly discovered mechanism enables precise gene regulation by combining DNA and RNA epigenetics
Posted by Shailesh Prasad in categories: biotech/medical, genetics
Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA epigenetics come in: a series of mechanisms that act as “markers” on genes, to control their activity without modifying the DNA or RNA sequence itself.
Until now, DNA and RNA epigenetics were studied as independent systems. These two mechanisms seemed to function separately, each playing its own role in distinct stages of the gene regulation process.
Perhaps that was a mistake.

Dynamical constraints on neural population activity
Posted by Dan Breeden in categories: computing, neuroscience
Oby, Degenhart, Grigsby and colleagues used a brain–computer interface to challenge monkeys to override their natural time courses of neural activity. They found the time courses to be highly robust, suggestive of network-level computational mechanisms.

Cosmic first: supermassive black hole caught “turning on” in real-time
Posted by Shubham Ghosh Roy in category: cosmology
Seven years ago, an outburst in a distant galaxy brightened and faded away. Afterwards, a new supermassive black hole jet emerged, but how?

Intracerebroventricular B7-H3-targeting CAR T cells for diffuse intrinsic pontine glioma: a phase 1 trial
Posted by Shubham Ghosh Roy in category: biotech/medical
In the final report of a phase 1 trial evaluating intracerebroventricular B7-H3-targeting CAR T cells in children and young adults with diffuse intrinsic pontine glioma, repeated intracranial infusions were feasible and well tolerated with a median overall survival of 19.8 months and 3 patients surviving over 40 months from diagnosis.

An Entire Book Was Written in DNA—and You Can Buy It for $60
Posted by Jose Ruben Rodriguez Fuentes in categories: biotech/medical, genetics, media & arts, robotics/AI
As the rate of humanity’s data creation increases exponentially with the rise of AI, scientists have been interested in DNA as a way to store digital information. After all, DNA is nature’s way of storing data. It encodes genetic information and determines the blueprint of every living thing on earth.
And DNA is at least 1,000 times more compact than solid-state hard drives. To demonstrate just how compact, researchers have previously encoded all of Shakespeare’s 154 sonnets, 52 pages of Mozart’s music, and an episode of the Netflix show “Biohackers” into tiny amounts of DNA.
