The economic life of cells      (via sciencedaily.com) 

A team has combined economic theory with biology to understand how natural systems respond to change. The researchers noticed a similarity between consumers' shopping behavior and the behavior of metabolic systems, which convert food into energy in our bodies. The team focused on predicting how different metabolic systems might respond to environmental change by using an economic tool called the Slutsky equation. Their calculations indicated that very different metabolic systems actually share previously unknown universal properties, and can be understood using tools from other academic fields. Metabolic processes are used in drug development, bioengineering, food production and other industries, so being able to predict how such systems will respond to change can offer many benefits.

Supercomputer used to simulate winds that cause clear air turbulence      (via sciencedaily.com) 

Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.

Researcher turns one of the basic rules of construction upside down      (via sciencedaily.com)     Original source 

Structural engineers are familiar with seventeenth-century scientist Robert Hooke's theory that a hanging chain will mirror the shape of an upstanding rigid arch. However, new research now shows that this common-held belief is incorrect because, regardless of the similarities, the hanging chain and the arch are two incompatible mechanical systems.

Forest can adapt to climate change, but not quickly enough      (via sciencedaily.com)     Original source 

America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.

Conservation in Indonesia is at risk, a team of researchers who study the region argues      (via sciencedaily.com)     Original source 

Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region's species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. A team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data transparency, and share research with the public in this and other regions of the world.

Machine learning takes materials modeling into new era      (via sciencedaily.com) 

The arrangement of electrons in matter, known as the electronic structure, plays a crucial role in fundamental but also applied research such as drug design and energy storage. However, the lack of a simulation technique that offers both high fidelity and scalability across different time and length scales has long been a roadblock for the progress of these technologies. Researchers have now pioneered a machine learning-based simulation method that supersedes traditional electronic structure simulation techniques. Their Materials Learning Algorithms (MALA) software stack enables access to previously unattainable length scales.

Arctic dust found to be a major source of particles that form ice crystals in Arctic low-level clouds      (via sciencedaily.com)     Original source 

Scientists in Japan have used a global climate model to show that dust from land without snow cover in the Arctic is a major source of particles that form ice crystals in Arctic low-level clouds. This finding could help improve predictions of Arctic warming, which is suggested to be much faster than in other parts of the world.

Expanding large-scale agriculture is escalating flooding in the largest South American breadbasket      (via sciencedaily.com)     Original source 

Driven by soaring international demand, extensive areas of grasslands, and forests across South American plains have rapidly been converted to the production of annual crops, such as soybean and maize. This agricultural expansion has been taking place at a staggering rate of 2.1 million hectares a year. A new study shows how these shifts to annual crop agriculture, which relies on rainfall rather than irrigation, is also rapidly disrupting the water table across the large flat regions of the Pampas and Chaco plains and contributing to significantly increased risks of surface flooding.
