Cardiovascular disease (CAD) is a major global public health issue, with mortality rates being significantly impacted by cold temperatures. Stable and reliable electrocardiogram (ECG) monitoring in cold environments is crucial for early detection and treatment of CAD. However, existing skin sensor struggle to balance freeze resistance, breathability, flexibility, conductivity and adhesion at cold temperatures.

- Succulence refers to the ability of plants to store water in their tissues, helping them function and survive in dry conditions.* -
- A study with nine shrub species showed that higher leaf and stem succulence leads to more usable water and a better ability to buffer changes in soil moisture.* -
- However, while root succulence helps prolong the time before plants desiccate, it doesn’t necessarily delay overall water loss, indicating different roles for succulence in aboveground vs. root systems.*
Article Synopsis
- Cardiac pacemakers are essential for treating arrhythmias, but traditional devices can cause issues like heart damage and infection risks due to their rigid components and reliance on batteries.
- A new wireless, battery-free bioelectronic device has been developed, featuring flexible and stretchable hydrogel electrodes that mimic heart tissue, enabling better ECG recording and pacing.
- This innovative device has shown effective performance for 31 days post-implantation in rats and has the potential for customizable pacing in live studies, significantly improving future cardiac treatment options.
Implantable cardiac pacemakers are crucial therapeutic tools for managing various cardiac conditions. For effective pacing, electrodes should exhibit flexibility, deformability, biocompatibility, and high conductivity/capacitance. Laser-induced graphene (LIG) shows promise due to its exceptional electrical and electrochemical properties.

In dry environments, plants with greater survival often have greater leaf succulence. However, it is unclear how leaf succulence relates to plant drought resistance strategies, including isohydry (closing stomata to maintain leaf water status) and anisohydry (adjusting cell turgor to tolerate low leaf water status), which exist on a continuum that can be quantified by hydroscape area (larger hydroscape area indicates more anisohydric).

- The study aims to explore the genetic connections between periodontitis, a common gum disease, and Alzheimer's disease (AD), suggesting that periodontitis may contribute to the progression of AD.
- Researchers analyzed gene expression data to identify differentially expressed genes (DEGs) linked to periodontitis and compared them with genes associated with AD to find shared "crosstalk genes."
- A total of 48 representative crosstalk genes were identified, along with key regulators and pathways, highlighting potential genetic links between the two diseases, with specific shared genes like C4A and IL1B noted for further research.
