How to stack graphene up to four layers

A novel method to grow multi-layered, single-crystalline graphene with a selected stacking order in a wafer scale has been developed. The researchers used Cu-Si alloy formation to control the number of graphene layers, allowing for uniform large-area single-crystalline layer-tunable multilayer graphene growth.

Rising temps put desert shrubs in high-efficiency mode

Research in the Mojave Desert shows that the brittlebush shrub has adapted to increased temperature and aridity by increasing its water use efficiency. Over a 39-year study period, the shrubs' ability to open their stomata was linked to changes in carbon isotopes, revealing a remarkable adjustment to the changing climate.

MU School of Nursing programs help nursing homes respond to COVID-19

The MU Sinclair School of Nursing is providing assistance to over 500 Missouri nursing homes, distributing personal protective equipment (PPE) and offering recommendations for infection control practices. This helps nursing home residents stay safe during the COVID-19 pandemic, with a focus on isolating sick patients and supporting staff.

Leaving money on the table to stay in the game

A new paper by Michael Price and James Holland Jones suggests that economic choices can be guided by evolutionary principles, such as diversifying to reduce risk. By keeping a mix of goats and camels, a Kenyan herder increases the odds of household survival, which is essential for long-term persistence.

Soft robot actuators heal themselves

Researchers created a self-healing polymer that mimics squid ring teeth, enabling fast and efficient repair of soft robotic actuators. The material can heal within one second, regaining its original strength and being fully biodegradable and recyclable.

Remote, real-time monitoring of post-operative lung transplant patients significantly decreases hospital stays

A two-year observational pilot study found that remote monitoring of post-operative lung transplant patients significantly reduced hospital stays and readmissions by 44% and 66%, respectively. The study also showed a significant reduction in hospital costs, with an average savings of $132,000 per patient per year.

Despite debate, even the world's oldest trees are not immortal

A recent study on ginkgoes found that they can 'escape senescence at the whole-plant level,' raising questions about the apparent lack of aging in centuries-old trees. However, plant biologist Sergi Munné-Bosch argues that these organisms still undergo physiological stress associated with senescence.

European and American maize: Same same, but different

Researchers have decoded the European maize genome, revealing significant differences in genetic content and genome structure compared to North American lines. These findings suggest that heterosis, a phenomenon increasing crop yields, may be influenced by variations in knob regions and gene regulation.

Developing a new strategy to selectively deliver therapies to the brain

Researchers developed a novel two-step targeting strategy to selectively deliver therapies to the brain by exploiting the high impermeability of the BBB. This approach allows for specific brain targeting with minimal accumulation in peripheral organs, paving the way for increased clinical translation of nanoparticle-based therapies.
