Robotic Soft Spider: Movement and Operation at Small Size Scale made Easy

Roboticists are envisioning a future in which soft, animal-inspired robots could be safely deployed in difficult-to-access natural and man-made environments, such as in delicate surgical procedures in the human body, or in spaces too small and unpredictable to be conquered with rigid robots or too dangerous for humans to work with rigid robots in.

Centimeter-sized soft robots have been created, but thus far it has not been possible to fabricate multifunctional flexible robots that can move and operate at smaller size scales.

Scanning Tunneling Microscopy Imaging Molecule-Covered Surface Structures

A study determined that by using scanning tunneling microscopy (STM), extremely high-resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. Real-space imaging with pattern recognition of a ligand-protected Ag374nanocluster at a sub-molecular resolution. The study was published in Nature Communications.

Lung Cancer Risk Assessment Improved by Biomarker panel

Biomarker-based risk profiling has the potential to improve lung cancer risk assessment, according to a study published online in JAMA Oncology. Florence Guida, Ph.D., from the International Agency for Research on Cancer in Lyon, France, and colleagues used samples from 108 ever-smoking patients with lung cancer diagnosed within a year of blood collection and samples from 216 smoking-matched controls to develop a lung cancer risk prediction model.

Subcutaneous Fat Fibrosis Links Obesity to Insulin Resistance in Chinese

A new study has discovered a key biological difference in how people of European and Chinese descent put on weight a finding that could help explain why Asians often develop type 2 diabetes at a much lower body weight than Caucasians.

The study was published in the Journal of Clinical Endocrinology & Metabolism, could be used to develop new biomarkers for diabetes risk in Asian populations and could even lead to new classes of drugs to slow the progression of the disease across all ethnicities.
