Summary: Researchers unveiled a groundbreaking discovery that DNA damage and brain inflammation are vital processes for forming long-term memories, particularly within the brain’s hippocampus.

Contrary to previous beliefs associating inflammation with neurological diseases, this study highlights inflammation’s critical role in memory formation through the activation of the Toll-Like Receptor 9 (TLR9) pathway following DNA damage in hippocampal neurons.

These findings not only challenge conventional views on brain inflammation but also caution against indiscriminate inhibition of the TLR9 pathway, given its importance in memory encoding and the potential risks of genomic instability.

Groundbreaking research has led to the creation of threofuranosyl nucleic acid (TNA), offering enhanced stability and therapeutic potential, with applications in drug delivery and diagnostics.

The DNA carries the genetic information of all living organisms and consists of only four different building blocks, the nucleotides. Nucleotides are composed of three distinctive parts: a sugar molecule, a phosphate group, and one of the four nucleobases adenine, thymine, guanine, and cytosine. The nucleotides are lined up millions of times and form the DNA double helix, similar to a spiral staircase.

Breakthrough in Nucleic Acid Research.

Some teens with autism use a different set of eye-movement patterns than their peers without autism while recognizing faces, say researchers at Yale Child Study Center (YCSC).

In a new data analysis, YCSC researchers including James McPartland, PhD, and Jason Griffin, PhD, found teens with autism…

Eye movements are part of the process of telling people apart and could provide information to clinicians about how people with autism process social information differently from non-autistic persons.

Researchers at Trinity College Dublin have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.

Two-dimensional transition metal carbides (MXene) possess attractive conductivity and abundant surface functional groups, providing immense potential in the field of electromagnetic wave (EMW) absorption. However, high conductivity and spontaneous aggregation of MXene suffer from limited EMW response. Inspired by dielectric–magnetic synergy effect, the strategy of decorating MXene with magnetic elements is expected to solve this challenge.
