Sugars that coat proteins are a possible drug target for pancreatitis
Pancreatitis is an inflammation of the pancreas that accounts for 275,000 hospitalizations in the United States annually. Patients who suffer from hereditary pancreatitis have a 40 to 50 percent lifetime risk of developing pancreatic cancer.

Skinflow: A soft robotic skin based on liquid transmission
Researchers at the Bristol Robotics Laboratory and the University of Bristol have recently developed a new soft robotic skin-like sensor that is based on fluidic transmission. This sensor, presented at the second IEEE International Conference on Soft Robotics (RoboSoft), could have interesting applications in a variety of fields, ranging from robotics to virtual reality (VR).

SPFCNN-Miner: A new classifier to tackle class-unbalanced data
Researchers at Chongqing University in China have recently developed a cost-sensitive meta-learning classifier that can be used when the training data available is high-dimensional or limited. Their classifier, called SPFCNN-Miner, was presented in a paper published in Elsevier's Future Generation Computer Systems.

One third of Cambodians infected with threadworm, study finds
Strongyloides stercoralis is a soil-transmitted threadworm that is endemic in many tropical and subtropical areas of the world. Now, researchers reporting in PLOS Neglected Tropical Diseases have conducted a nation-wide parasitology survey of the Cambodian population and concluded that nearly a third of the studied population is infected with S. stercoralis.

Artificial intelligence identifies 'kissing bugs' that spread Chagas disease
New research from the University of Kansas shows machine learning is capable of identifying insects that spread the incurable disease called Chagas with high precision, based on ordinary digital photos. The idea is to give public health officials where Chagas is prevalent a new tool to stem the spread of the disease and eventually to offer identification services directly to the general public.

New p53 gene discovery sheds light on how to make cancer therapies more effective
Scientists at VCU Massey Cancer Center have discovered that the loss of a protein called DBC1 in breast cancer cells leads to the dysregulation of normal anti-cancer functions, contributing to cancer cell growth and resistance to therapies. By restoring the expression of this protein, doctors may be able to help prevent the development of cancer and increase the effectiveness of common cancer treatments.

Team proposes stochastic model to explain microbiome composition
All living things—from the simplest animal and plant organisms to the human body—live closely together with an enormous abundance of microbial symbionts, which colonise the insides and outsides of their tissues. The functional collaboration of host and microorganisms, which scientists refer to as a metaorganism, has only recently come into the focus of life science research. Today we know that we can only understand many of life's processes in connection with the interactions between organism and symbionts. The Collaborative Research Centre (CRC) 1182 "Origin and Function of Metaorganisms" at Kiel University (CAU) aims to understand the communication and the functional consequences of host-microbe relationships.

Scaffold helps cells repair torn meniscus in lab tests
About a million times a year, Americans with a torn meniscus in their knee undergo surgery in hopes of a repair. Certain tears can't be fixed or won't heal well, and many patients later suffer osteoarthritis from the injury.

Teaching AI agents navigation subroutines by feeding them videos
Researchers at UC Berkeley and Facebook AI Research have recently proposed a new approach that can enhance the navigation skills of machine learning models. Their method, presented in a paper pre-published on arXiv, allows models to acquire visuo-motor navigation subroutines by processing a series of videos.
