Florida Wildlife Corridor eases worst impacts of climate change      (via sciencedaily.com)     Original source 

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.

How seaweed became multicellular      (via sciencedaily.com)     Original source 

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.

A new spin on organic shampoo makes it sudsier, longer lasting      (via sciencedaily.com)     Original source 

While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.

Nanoscale movies shed light on one barrier to a clean energy future      (via sciencedaily.com)     Original source 

New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.

New report 'braids' Indigenous and Western knowledge for forest adaptation strategies against climate change      (via sciencedaily.com)     Original source 

Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks -- all intensified by climate change -- are straining many national forests and surrounding lands in the United States. A report outlines a new approach to forest stewardship that 'braids together' Indigenous knowledge and Western science to conserve and restore more resilient forestlands.
