Thyroid hormone use may raise death risk in older adults

A large study has found that thyroid hormone replacement therapy in older adults is associated with a higher risk of death compared to no treatment. The study, published in the Journal of the Endocrine Society, suggests that age-specific TSH reference intervals can help determine the threshold for thyroid hormone treatment.

Two COVID-19 papers published in PLOS ONE

Two PLOS ONE studies use the SIRD model to forecast COVID-19 spread and examine patient CT scans for clinical features with mortality. The models predict a significant number of infections (45,000+ in Hubei) and deaths (2,700+) by February 29. In contrast, patients with severe lung features were more likely to die from the virus.

Amyloid formation drives brain tissue loss in animal studies

A study published in eLife found that amyloid plaque formation directly causes brain tissue loss in animals, leading to progressive memory loss and loss of brain matter. However, lithium has been shown to reduce the life-shortening effects of this loss, suggesting a potential strategy to slow Alzheimer's disease progression.

Untangling the social lives of spiders

A recent study in Genome Biology and Evolution explores the genetic underpinnings of spider sociality, revealing rapidly evolving genes involved in behavior, immunity, and brain-specific expression. The analysis found differences in metabolic processes between solitary and social spiders, hinting at distinct hunting and feeding behaviors.

Mucus and the coronavirus

Biomedical engineer Jessica Kramer is researching how different compositions of mucus play a part in transferring coronaviruses from person to person. Her study may help identify those who are 'super-spreaders' and those more vulnerable to infection, leading to faster and more accurate data on virus spread.

Scientists tap unused energy source to power smart sensor networks

Researchers have created a device capable of converting low-level magnetic fields into usable electricity, with 400% higher power output than existing technology. This technology has significant implications for designing self-powered wireless sensor networks in smart buildings, potentially leading to substantial energy savings.

Textile-fiber-embedded multiluminescent device for future wearable devices

Dr. Soon Moon Jeong's team creates a new light-emitting technology using in-plane electro-luminescent technology that inserts electrodes into a luminous layer, overcoming existing limitations. The device emits light more flexibly and stably than traditional devices, with applications in wearable devices and textiles.

Discovery of new biomarker in blood could lead to early test for Alzheimer's disease

Researchers discovered a biomarker for early detection of Alzheimer's disease in the form of high levels of RNA produced by the PHGDH gene. The study, published in Current Biology, suggests that overproduction of extracellular RNA by the PHGDH gene in elderly individuals may serve as an early warning sign of Alzheimer's disease.

Assessing forests from afar

Researchers suggest a more detailed approach to assessing forest health, focusing on protected areas with finer scale data. This method can help identify non-intact forests and track changes in forest cover over time.
