Machine learning could eliminate unnecessary treatments for children with arthritis

Arthritis is not just an ailment of old age—it can affect children too, causing lifelong pain and disability in its most severe forms. Fortunately, some kids grow out of it. Knowing which patients will develop milder forms of disease could spare them unnecessary treatment and potential medication side effects but currently doctors have no way of predicting disease course or severity.

Why photography fans are geeking out over assembly video of fisheye lens

The superstar of a fisheye lens emerged this month, shown in a video, where a team fashioned a custom fisheye lens that has a 270-degree field of view. Wow, as that was being dubbed as "insane" and "monster-like" but the descriptions were all conveyed with a wide-eyed measure of affection for Roger Cicala, founder of Lensrental.com.

An existing drug may have therapeutic potential in mitochondrial disease

New preclinical findings from extensive cell and animal studies suggest that a drug already used for a rare kidney disease could benefit patients with some mitochondrial disorders—complex conditions with severe energy deficiency for which no proven effective treatments exist. Future clinical research is needed to explore whether the drug, cysteamine bitartrate, will meaningfully benefit patients.

High-powered fuel cell boosts electric-powered submersibles, drones

The transportation industry is one of the largest consumers of energy in the U.S. economy with increasing demand to make it cleaner and more efficient. While more people are using electric cars, designing electric-powered planes, ships and submarines is much harder due to power and energy requirements.

Electrically-heated silicate glass appears to defy Joule's first law

Characterizing and predicting how electrically-heated silicate glass behaves is important because it is used in a variety of devices that drive technical innovations. Silicate glass is used in display screens. Glass fibers power the internet. Nanoscale glass devices are being deployed to provide breakthrough medical treatments such as targeted drug-delivery and re-growing tissue.

Ikea curtains break down pollutants, highlight interest in fabric purifiers

Can you use textiles to clean the air? Take sunlight. Add a film coating to fabric. And you get curtains that destroy pollutants and purify the air inside your home. The recipe is being touted by Ikea. Along with bunk beds and bedside tables, some thinkers at Ikea have been looking into technologies that can address indoor air pollution without having to resort to more complex filtering systems or electric power.

You recognize your face even when you don't 'see' it

Given the limited capacity of our attention, we only process a small amount of the sights, sounds, and sensations that reach our senses at any given moment—what happens to the stimuli that reach our senses but don't enter awareness? Research suggests that certain stimuli—specifically, your own face—can influence how you respond without you being aware of it. The findings are published in Psychological Science, a journal of the Association of Psychological Science.

Recognizing disease using less data

As artificial intelligence systems learn to better recognize and classify images, they are becoming highly-reliable at diagnosing diseases, such as skin cancer, from medical images. But as good as they are at detecting patterns, AI won't be replacing your doctor any time soon. Even when used as a tool, image recognition systems still require an expert to label the data, and a lot of data at that: it needs images of both healthy patients and sick patients. The algorithm finds patterns in the training data and when it receives new data, it uses what it has learned to identify the new image.

Brain-inspired artificial intelligence in robots

Research groups at KAIST, the University of Cambridge, Japan's National Institute for Information and Communications Technology, and Google DeepMind argue that our understanding of how humans make intelligent decisions has now reached a critical point in which robot intelligence can be significantly enhanced by mimicking strategies that the human brain uses when we make decisions in our everyday lives.

Inherited mutations may play a role in pancreatic cancer development

A small, retrospective study has found that, in patients with particular pancreatic duct lesions, the presence of an inherited mutation in a pancreatic cancer susceptibility gene may increase the patients' risk of developing pancreatic cancer. To verify these results and learn more about the development of this deadly cancer, the researchers recommend more genetic studies. Their hope—in line with the goals of precision medicine—is to eventually find a better way to guide patient care, dividing patients, for example, into those who need regular screening versus immediate surgery or other early interventions.
