Machine learning may help identify ideal dementia treatments

Machine learning may help identify ideal dementia treatments

Health
Oct. 22 (UPI) -- Machine learning may someday allow physicians to prescribe the best treatment for dementia, according to a study. Researchers devised and applied a new algorithm that can spot different patterns of progression in patients with a range of dementias in MRI scans, including Alzheimer's disease. The findings were published this month in the journal Nature Communications. "This new algorithm has the unique ability to reveal groups of patients with different variants of disease," Dr. Daniel Alexander, a professor in the University College London Center for Medical Image computing, said in a press release. "One key reason for the failure of drug trials in Alzheimer's disease is the broad mixture of very different patients they test; a treatment with a strong effect on a particul...

Machine learning could help regulators identify environmental violations

Science
Oct. 1 (UPI) -- Regulatory agencies tasked with protecting environmental and public health are regularly understaffed and underfunded, but new research suggests machine learning could help officials more effectively monitor potential violators. The Environmental Protection Agency and partnering state agencies are responsible for monitoring the regulatory compliance of 300,000 facilities. Regulators, however, only have the resources to inspect less than 10 percent of those facilities each year. To help the EPA catch violations, student researchers at Stanford University designed a model to identify facilities most likely to fail an inspection. Scientists trained the machine learning to interpret a variety of risk factors, including the facility's location, industry and inspection history. ...

Chasing quakes with machine learning

Science
Scientists have used machine learning to calculate the pattern of aftershocks following an earthquake.Aftershocks are further quakes that follow the "main shock". They are by definition smaller, but sometimes not by much.This is the first time a machine learning method has been used to work out where they might happen.Researchers hope this and similar techniques will improve our understanding of earthquake behaviour."If you think about making forecasts of earthquakes," says study co-author Prof Brendan Meade of Harvard University, "you want to do three things; you want to predict when they're going to be, you want to say something about how large they're going to be and about where they're going to be."What we wanted to do is to tackle the last leg of thi...

How to build a real time machine

Science
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.Ron Mallett has a dream: He wants to travel in time.This isn't mere fantasy - Mallett is a respected professor of physics."I think of myself as being an ordinary person with a passion, and my passion is the possibility of time travel," he says.Prof Mallett has wanted to build a time machine for most of his life. His passion, he explains, can be traced to a tragic event early in his life.Ron's father, a heavy smoker, died of a heart attack at the age of 33 - when Prof Mallett was just 10 years of age. Ron was deva...
