Unlocking the secret strength of marine mussels      (via sciencedaily.com)     Original source 

How do you create strong, yet quick-release connections between living and non-living tissues? This is a question that continues to puzzle bioengineers who aim to create materials that bond together for advanced biomedical applications. Looking to nature for inspiration, this research zeroed in on the marine mussel byssus, a fibrous holdfast, which these bivalve mollusks use to anchor themselves in seashore habitats.

Rare ant species rediscovered in North Carolina trees      (via sciencedaily.com)     Original source 

There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.

Measuring long-term heart stress dynamics with smartwatch data      (via sciencedaily.com)     Original source 

Biomedical engineers have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The new 'digital twins' computational framework captures personalized arterial forces over 700,000 heartbeats to better predict risks of heart disease and heart attack. The advance is an important step toward evaluating the risks of heart disease or heart attack over months to years.

The Fens of eastern England once held vast woodlands      (via sciencedaily.com)     Original source 

The Fens of eastern England, a low-lying, extremely flat landscape dominated by agricultural fields, was once a vast woodland filled with huge yew trees, according to new research. Scientists have studied hundreds of tree trunks, dug up by Fenland farmers while ploughing their fields. The team found that most of the ancient wood came from yew trees that populated the area between four and five thousand years ago.

First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat      (via sciencedaily.com)     Original source 

In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'

New computer code for mechanics of tissues and cells in three dimensions      (via sciencedaily.com)     Original source 

Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of energy. Such continuously driven materials are called 'active matter'. The mechanics of cells and tissues can be described by active matter theory, a scientific framework to understand shape, flows, and form of living materials. The active matter theory consists of many challenging mathematical equations. Scientists have now developed an algorithm, implemented in an open-source supercomputer code, that can for the first time solve the equations of active matter theory in realistic scenarios. These solutions bring us a big step closer to solving the century-old riddle of how cells and tissues attain their shape and to designing artificial biological machines.
