The stem cell-based embryo model (SCBEM) takes advantage of the flexibility of pluripotent stem cells (non-reproductive cells that can give rise to many different types of cells) to resemble that of embryos. While this model has helped to advance research in diseases and develop therapies or treatments, it has also sparked international debate on what regulations should be placed on this type of experimentation. Researchers reviewed what countries are doing to regulate SCBEM and proposed what regulation should look like for this field of stem cell research to move forward in a manner that everyone can agree is ethically sound.

Dr. Dae-Yoon Kim and his team at the Korea Institute of Science and Technology (KIST) Composite Materials Research Institute have succeeded in constructing the coil of an electric motor using only carbon nanotubes (CNTs) without any metals, and realizing it to the point where it can actually run.

Complex illnesses are not caused by one gene but groups of genes. The number of gene combinations is too enormous to analyze comprehensively. New AI model focuses on gene expression changes to identify key genes and their collective influence on disease.

As solar energy becomes more affordable and widespread, farmland has emerged as a prime location for large-scale solar development. But with this expansion comes a persistent question: Do nearby property values suffer when solar farms move in? In a new paper published in the Proceedings of the National Academy of Sciences, researchers in Virginia Tech’s Department of Agricultural and Applied Economics in the College of Agriculture and Life Sciences looked at millions of property sales and thousands of commercial solar sites to shed some light on one of the mostly commonly cited downsides of large-scale solar adoption. 

A study in Science Advances that describes a new soft robotic system was co-led by Harvard Professor L. Mahadevan in collaboration with Professor Ho-Young Kim at Seoul National University. Their work paves new directions for future, low-power swarm robotics.

The new robots, called link-bots, are comprised of centimeter-scale, 3D-printed particles strung into V-shaped chains via notched links and are capable of coordinated, life-like movements without any embedded power or control systems.
