How epigenetics influence memory formation
Posted by Shubham Ghosh Roy in categories: biotech/medical, genetics, neuroscience
When we form a new memory, the brain undergoes physical and functional changes known collectively as a “memory trace.” A memory trace represents the specific patterns of activity and structural modifications of neurons that occur when a memory is formed and later recalled.
But how does the brain “decide” which neurons will be involved in a memory trace? Studies have suggested that the inherent excitability of neurons plays a role, but the currently accepted view of learning has neglected to look inside the command center of the neuron itself, its nucleus. In the nucleus, there seems to be another dimension altogether that has gone unexplored: epigenetics.
Inside every cell of a given living organism, the genetic material encoded by the DNA is the same, yet the various cell types that make up the body, like skin cells, kidney cells, or nerve cells each express a different set of genes. Epigenetics is the mechanism of how cells control such gene activity without changing the DNA sequence.

New Model Challenges Giant Planet Formation Hypothesis
Posted by Laurence Tognetti, Labroots Inc. in categories: evolution, physics, space
How do giant planets form and is this process slow or fast based on the amount of available dust used to build those planets? This is what a recent study published in Astronomy & Astrophysics hopes to address as a team of researchers from Germany investigated how sub-micron-sized dust kicks off the planetary formation process within a protoplanetary disc. This study holds the potential to help scientists better understand the formation and evolution of planets throughout our solar system and exoplanetary systems, as well.
For the study, the researchers developed first-of-its-kind model to involve all constituents responsible for the physical processes that from planets. Focusing on sub-micron-sized dust, they included factors such as pebble accumulation, planetary gas buildup, planetary migration, and dust buildup, among others. In the end, they found that ring-shaped disturbances in the protoplanetary disk, which they refer to as substructures, can result in multiple gas giants’ formation in rapid sequence.
Dr. Til Birnstiel, who is a professor of theoretical astrophysics at Ludwig-Maximilians-Universität München and a co-author on the study, said: “When a planet gets large enough to influence the gas disk, this leads to renewed dust enrichment farther out in the disk. In the process, the planet drives the dust – like a sheepdog chasing its herd – into the area outside its own orbit.”

10 Most Dangerous Staircases in The World (PHOTOS)
Posted by Chris Smedley in category: transportation
Dangerous Train Routes In The World… 😳 😘❤️
Also read:
As you climb these steps, make sure to watch where you step. Here are some of the most spectacular and dangerous staircases in the world. Stairs have been built for a very long time to aid in the ascent of heights and to lessen the amount of work that is required for this. However, in other regions of the world, stairs are so terrible that they appear to be nothing more than a series of corridors going to the underworld.

New coating removes solar panel defects, boosts efficiency to 31%
Posted by Genevieve Klien in categories: solar power, sustainability
Silicon wafers produced by the Czochralski process with micrometer-scale pyramidal structural elements on their surfaces are significantly cheaper.
These microtextures capture more light because they are less reflective than a smooth surface. However, coating these wafers with perovskite results in many defects in the crystal lattice, which affect the electronic properties.
However, the team of researchers has developed a strategy for surface passivation that allows the surface defects of the perovskite layer to be smoothed out.

Synthesis of ceramic nanospheres with tunable electromagnetic wave absorption performance
Posted by Dan Breeden in categories: biotech/medical, health, internet, security
Microwave technology has dramatically progressed, marked by the arrival of the 5G era, owing to the advantages of electromagnetic waves in long-distance, wireless, and high-speed transmissions. However, electromagnetic wave pollution problems such as electromagnetic wave interference and electromagnetic wave radiation are becoming increasingly serious.
Electromagnetic wave pollution not only affects the normal operation of electronic equipment, greatly threatens the information security of the scientific community, but also endangers human health and is a possible cause of cancer and sensitized diseases.
SiOC precursor ceramics have great application potential in electromagnetic protection because of their advantages such as lightweight, high-temperature resistance, and molecular designability. The main challenge of polymer-derived ceramic-based composites for electromagnetic wave absorption is the single loss mechanism, resulting in inferior electromagnetic wave attenuation ability.
