Increasing complexity challenges strategic management

A recent study by Sami Tikkanen at the University of Vaasa highlights the need for new strategies in managing complexity in strategic management. The research found that reducing uncertainties, managing interdependencies, and creating favourable conditions for self-organisation can help organisations adapt to changing environments.

Tumor cells suffer copper withdrawal

Researchers develop a method to remove copper from tumor cells, killing them. The nanofibers use copper-binding domains to grasp copper ions, disrupting cellular homeostasis and increasing oxidative stress.

Gut feelings: Social connections change our microbiomes

A new Yale-led study reveals that people's social connections influence their gut microbiomes, with stronger ties resulting in more similar microbial compositions. The researchers found that friends and non-familial relationships exhibit similarities beyond chance, suggesting a transfer of microbes through social networks.

Growing soybeans has a surprisingly significant emissions footprint, but it’s ripe for reduction

A new study by Iowa State University researchers finds that nearly half of soybean-related emissions come from the natural processes in soil, which can be mitigated through strategies like planting winter cover crops and adjusting planting schedules. These solutions have been found to reduce emissions by one-third while increasing yields.

How protective antibodies get in malaria’s way

Researchers at Fred Hutchinson Cancer Center have made a breakthrough in understanding how protective antibodies can target malaria parasites. By analyzing the structure of these antibodies and their interaction with the parasite's protein, the team has identified a weak spot that could be targeted by vaccines to prevent severe disease.

Microbiologists join the battle against climate change

Eighteen microbiologists propose a global science-based task force to develop and implement microbiological solutions grounded in ecological knowledge. Microorganisms can capture carbon, break down pollutants, produce biofuel, and strengthen ecosystems, offering numerous potential solutions to mitigate the effects of climate change.

Analyzing the structure-performance relationships of electrocatalysts

The study proposes a strategy to use spinel oxides, particularly those involving rare-earth cerium substitution, to improve the oxygen evolution reaction. The team found that adding Ce promotes the lattice oxygen pathway, leading to highly active spinel oxide catalysts for electrochemical reactions.

Developing an evaluation scale to predict the risk of requiring long-term care based on three simple physical performance tests

Researchers developed an evaluation scale based on three physical performance tests: single-leg balance, timed up and go, and sit-to-stand. The scale predicts long-term care risk among older adults with high accuracy, particularly those with scores of 41 or more. It provides a comprehensive assessment method for Japanese older adults.
