The generation and maintenance of protective immunity is a dynamic interplay between host and environment that is impacted by age. Understanding fundamental changes in the healthy immune system that occur over a lifespan is critical in developing interventions for age-related susceptibility to infections and diseases. Here, we use multi-omic profiling (scRNA-seq, proteomics, flow cytometry) to examined human peripheral immunity in over 300 healthy adults, with 96 young and older adults followed over two years with yearly vaccination. The resulting resource includes scRNA-seq datasets of 16 million PBMCs, interrogating 71 immune cell subsets from our new Immune Health Atlas. This study allows unique insights into the composition and transcriptional state of immune cells at homeostasis, with vaccine perturbation, and across age. We find that T cells specifically accumulate age-related transcriptional changes more than other immune cells, independent from inflammation and chronic perturbation. Moreover, impaired memory B cell responses to vaccination are linked to a Th2-like state shift in older adults’ memory CD4 T cells, revealing possible mechanisms of immune dysregulation during healthy human aging. This extensive resource is provided with a suite of exploration tools at https://apps.allenimmunology.org/aifi/insights/dynamics-imm-health-age/ to enhance data accessibility and further the understanding of immune health across age.

Located in the Xinyi District of Taipei, Tao Zhu Yin Yuan, more famously known as the Agora Garden, is an ultra-modern residential building. It has been a point of observation and study for many designers for its peculiar twisted structure. The building has a height of 306 ft comprising 21 floors above ground and three basements. It has a LEED gold and diamond label and has also won multiple awards.

A paralysed man who had an extreme form of locked-in syndrome and heard a nurse say he was “brain dead” has become the first ever to recover after hearing medical professionals debating whether or not to switch off his life support.

In 2017, Jacob Haendel was living a normal life as a head chef in Boston, Massachusetts but in the space of a few weeks, his life was turned upside down after he was diagnosed with acute toxic progressive leukoencephalopathy, which progressed into locked-in syndrome and forced his body would slowly shut down. An extreme form of locked-in syndrome is a condition where a patient is aware but cannot move or communicate verbally due to complete paralysis and can be caused by brain trauma, infection or exposure to toxins.

Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way’s disk. Results of the study, detailed in a research paper published October 16 on the preprint server arXiv, yield crucial information regarding the nature of this stellar stream.

The type of semiconductive nanocrystals known as quantum dots are both expanding the forefront of pure science and also hard at work in practical applications including lasers, quantum QLED televisions and displays, solar cells, medical devices, and other electronics.

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain’s neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. University of Basel researchers report in the journal Nature how neuronal networks in the mouse brain are fine-tuned.

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this “negativity bias,” which can fuel the development of depressive symptoms, had previously remained largely unknown.

As technology advances, the limitations of conventional electronic computers are becoming increasingly apparent, especially when tackling complex computational challenges. NP-complete problems, which grow exponentially with size, represent some of the toughest puzzles in computer science. These issues have significant implications across various fields, including biomedicine, transportation, and manufacturing. In the quest for more effective…

A new study sheds light on how highly creative individuals, such as visual artists and scientists, may have brains that function differently compared to others. The research, published in Psychology of Aesthetics, Creativity, and the Arts, reveals that people who exhibit exceptional creativity—referred to as “Big C” creative individuals—demonstrate…
