From genes to jeans: New genetic insights may lead to drought resilient cotton      (via sciencedaily.com)     Original source 

Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.

Hair follicle models from the 3D printer      (via sciencedaily.com)     Original source 

Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them. In order to investigate this scenario more closely in the laboratory, researchers have now developed a model with human hair follicles embedded in a matrix produced using 3D printing. In the future, this model can be used to test the effectiveness of new drug candidates against corresponding pathogens directly on human follicles.

Scientists work to build 'wind-up' sensors      (via sciencedaily.com)     Original source 

An international team of scientists has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.

Climate is most important factor in where mammals choose to live, study finds      (via sciencedaily.com)     Original source 

Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.

Researchers explore the interplay between high-affinity DNA and carbon nanotubes      (via sciencedaily.com)     Original source 

Single-walled carbon nanotubes (SWCNTs) hold promise for biomedicine and nanoelectronics, yet the functionalization with single-stranded DNA (ssDNA) remains a challenge. Researchers using high-affinity ssDNA sequences identified through high-throughput selection. They demonstrated the effectivity and stability of these constructs using molecular dynamics simulations. Machine-learning models were used to accurately predict patterns that govern ssDNA-SWCNT binding affinity. These findings provide valuable insights into the interactions between ssDNA and SWCNTs.

Mixed approach to reforestation better than planting or regeneration alone      (via sciencedaily.com)     Original source 

Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.

Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse      (via sciencedaily.com)     Original source 

Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research.
