A friction reduction system for deformable robotic fingertips

Researchers at Kanazawa University have recently developed a friction reduction system based on a lubricating effect, which could have interesting soft robotics applications. Their system, presented in a paper published in Taylor & Francis' Advanced Robotics journal, could aid the development of robots that can efficiently manipulate objects under both dry and wet conditions.

Brain changes in autism traced to specific cell types

Changes in gene activity in specific brain cells are associated with the severity of autism in children and young adults with the disorder, according to a UC San Francisco study of postmortem brain tissue. The study's new insights into how specific changes in gene expression contribute to the disease's symptoms by altering the function of brain circuits provides an important foundation for the development of treatments for the disorder, the authors say.

Stop gambling with black box and explainable models on high-stakes decisions

As the buzzwords "machine learning" continue to grow in popularity, more industries are turning to computer algorithms to answer important questions, including high-stakes fields such as healthcare, finance and criminal justice. While this trend can lead to major improvements in these realms, it can also lead to major problems when the machine learning algorithm is a so-called "black box."

Artificial intelligence shines light on the dark web

Beneath the surface web, the public form of the internet you use daily to check email or read news articles, exists a concealed "dark web." Host to anonymous, password-protected sites, the dark web is where criminal marketplaces thrive in the advertising and selling of weapons, drugs, and trafficked persons. Law enforcement agencies work continuously to stop these activities, but the challenges they face in investigating and prosecuting the real-world people behind the users who post on these sites are tremendous.

Enhanced anticancer compound may allow precise activation and tracking of treatment

Researchers at The Wistar Institute and the University of South Florida have advanced a novel compound that specifically targets the endoplasmic reticulum (ER) stress response that is frequently hyperactivated in cancer and promotes survival of cancer cells during stressful conditions. The new compound has unique chemical properties that allow for precise activation and can be used for tracking its activity in vivo thanks to the emission of fluorescence. Research was published online in the Journal of Medicinal Chemistry.

CRISPR catches out critical cancer changes

In the first large-scale analysis of cancer gene fusions, which result from the merging of two previously separate genes, researchers at the Wellcome Sanger Institute, EMBL-EBI, Open Targets, GSK and their collaborators have used CRISPR to uncover which gene fusions are critical for the growth of cancer cells. The team also identified a new gene fusion that presents a novel drug target for multiple cancers, including brain and ovarian cancers.
