Our brains change more rapidly at various times of our lives, as though life’s clock was ticking faster than usual. Childhood, adolescence and very old age are good examples of this.
Yet for much of adulthood, the same clock seems to tick fairly regularly. One lap around the Sun; one year older.
However, there may be a stage of life when the brain’s clock starts speeding up. The brain starts changing without you necessarily noticing it. It may even be caused (partly) by what’s in your blood.
A combination of widely available antibiotics may be able to treat heart failure after researchers found that the therapy regenerates heart cells in animals.

Delve into insights from a captivating retrospective study on Surgical Management and Predictors of Postoperative Complications of Retrosternal Goiters!

Background: The preferred standard treatment for retrosternal goiter (RSG), a slow-growing, often benign tumor, remains thyroidectomy. An alternative strategy may be required when the goiter is intrathoracic. Data on the results of RSG procedures are rarely reported. Careful patient selection and assessment are critical to avoiding an unexpected sternotomy during surgery and postoperative complications. This study aims to examine the clinical findings and treatment outcomes of RSG and to identify the variables affecting postoperative complications in a resource-limited setting.
Method: A retrospective study was conducted at Al-Thawra Modern General Hospital in Sana’a, Yemen, on 69 patients diagnosed with RSG and undergoing thyroidectomy between April 2019 and February 2023.
The advent of CRISPR gene editing, along with nanopore genome sequencing and single-cell RNA sequencing, has allowed the study of host-microbe interactions with newfound accuracy and power. The studies taking advantage of these tools have provided insights with never-before seen precision and, excitingly, have revealed surprising findings on principles of host-microbe interactions. This special issue reviews and interprets host immunological and developmental interactions with the resident microbiome. The articles reflect on evolutionary principles guiding how hosts interact with their commensal microbiota and offer new techniques and directions for research that we hope will advance the field in the years to come.

Researchers have made a pioneering discovery that astrocytes, cells within the central nervous system traditionally not associated with immune functions, are capable of developing what’s being called an “immune memory.” This capability…
Summary: Astrocytes, traditionally non-immune cells within the central nervous system, possess the ability to develop an immune memory, responding more vigorously to subsequent immune challenges. This groundbreaking study reveals that through an epigenetic mechanism involving the enzymes p300 and ATP-citrate lyase (ACLY), astrocytes enhance their pro-inflammatory responses, a trait similar to the immune memory seen in adaptive immunity.
The findings, which have been observed in both mouse models of multiple sclerosis (MS) and human cell samples, suggest that astrocyte immune memory may play a significant role in chronic neurological disorders, offering new insights into disease pathology and potential therapeutic targets to mitigate CNS inflammation.
Importantly, the superior temporal sulcus (STS), and superior temporal gyrus (STG) are considered core areas for multisensory integration (17, 38), including for olfactory–visual integration (44). The STS was significantly connected to the IPS during multisensory integration, as indicated by the PPI analysis ( Fig. 3 ) focusing on functional connectivity of IPS and whole-brain activation. Likewise, the anterior and middle cingulate cortex, precuneus, and hippocampus/amygdala were activated when testing sickness-cue integration-related whole-brain functional connectivity with the IPS but were not activated when previously testing for unisensory odor or face sickness perception. In this context, hippocampus/amygdala activation may represent the involvement of an associative neural network responding to threat (24) represented by a multisensory sickness signal. This notion supports the earlier assumption of olfactory-sickness–driven OFC and MDT activation, suggested to be part of a neural circuitry serving disease avoidance. Last, the middle cingulate cortex has recently been found to exhibit enhanced connectivity with the anterior insula during a first-hand experience of LPS-induced inflammation (26), and this enhancement has been interpreted as a potential neurophysiological mechanism involved in the brain’s sickness response. Applied to the current data, the middle cingulate cortex, in the context of multisensory-sickness–driven associations between IPS and whole-brain activations, may indicate a shared representation of an inflammatory state and associated discomfort.
In conclusion, the present study shows how subtle and early olfactory and visual sickness cues interact through cortical activation and may influence humans’ approach–avoidance tendencies. The study provides support for sensory integration of information from cues of visual and olfactory sickness in cortical multisensory convergences zones as being essential for the detection and evaluation of sick individuals. Both olfaction and vision, separately and following sensory integration, may thus be important parts of circuits handling imminent threats of contagion, motivating the avoidance of sick conspecifics (3, 5).

Synopsis | Dying for Life (2024)
For as long as mankind has been capable of thought, we have known the truth about life: that it ends in death. But as our scientific knowledge increases, there are more and more believers who think humans will soon be clever enough to halt the inevitability of their mortality. Others of course will never be convinced living forever is either possible or desirable. They say the idea that death could one day be considered a curable disease is nonsense. But advocates of cryonics, including many Australians, tell Amelia Adams now is the time to start getting ready for life after life.
