Big data sets are full of dirty data, and these outliers, typos and missing values can produce distorted models that lead to wrong conclusions and bad decisions, be it in healthcare or finance. With so much at stake, data cleaning should be easier.

It is now possible for machines to learn how natural or artificial systems work by simply observing them, without being told what to look for, according to researchers at the University of Sheffield.
This could mean advances in the world of technology with machines able to predict, among other things, human behaviour.

PORTLAND, Ore. - Researchers at Oregon State University and other institutions have discovered a type of drug delivery system that may offer new hope for patients with a rare, ultimately fatal genetic disorder - and make what might become a terrible choice a little easier.
No treatment currently exists for this disease, known as Niemann Pick Type C1 disease, or NPC1, that affects about one in every 120,000 children globally, and results in abnormal cholesterol accumulation, progressive neurodegeneration and eventual death.

A research group under the leadership of Linköping University Professor Markus Heilig has identified an enzyme whose production is turned off in nerve cells of the frontal lobe when alcohol dependence develops. The deficiency in this enzyme leads to continued use of alcohol despite adverse consequences.
The discovery is now published in the number-one ranked psychiatric journal from the Nature Publishing Group, and could mean completely new possibilities for treating alcoholism.

CORVALLIS, Ore. - Researchers have discovered a mechanism of intercellular communication that helps explain how biological systems and actions - ranging from a beating heart to the ability to hit a home run - function properly most of the time, and in some scenarios quite remarkably.
The findings are an important basic advance in how cell sensory systems function, they shed light on the poorly-understood interaction between cells - and they also suggest that some of the damage done by cancer cells can be seen as a "failure to communicate."

There's no human instinct more basic than speech, and yet, for many people, talking can be taxing. 1 in 14 working-age Americans suffer from voice disorders that are often associated with abnormal vocal behaviors - some of which can cause damage to vocal cord tissue and lead to the formation of nodules or polyps that interfere with normal speech production.

We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research led by University of Maryland School of Public Health researchers examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain regions, including the hippocampus, after they stopped their exercise routines.
