Artificial intelligence used to predict cancer growth

Health
Scientists have used artificial intelligence to predict how cancers will progress and evolve.This could help doctors design the most effective treatment for each patient.A team led by the Institute of Cancer Research London (ICR) and the University of Edinburgh developed a new technique known as Revolver (Repeated Evolution of Cancer).This picks out patterns in DNA mutation within cancers and uses the information to forecast future genetic changes.The researchers said the ever-changing nature of tumours was one of the biggest challenges in treating cancer - with cancers often evolving to a drug-resistant form.Breast tumoursHowever, if doctors can predict how a tumour will evolve, they could intervene earlier to stop cancer in its...
Study to help scientists predict climate change's impact on biodiversity

Study to help scientists predict climate change's impact on biodiversity

Science
Aug. 30 (UPI) -- A new study suggests a species ability to survive and adapt to climate change depends on the speed at which climate conditions shift. The climate has been changing for hundreds of millions of years. Along the way, plant and animal communities have adjusted and persevered. But anthropogenic climate change is different, it's happening at greater speeds and on a greater magnitude. To better understand how plants and animals will respond in the future, scientists need to more accurately characterize how climate change has impacted biodiversity in the past. A new survey of climate change throughout Earth's history suggests most plants and animals have shown the ability to move and adapt to climate change. However, the latest findings -- detailed this week in the journal Trend...
Wearable devices could predict risk for senior falls

Wearable devices could predict risk for senior falls

Health
July 12 (UPI) -- Wearable devices with motion sensors can predict older participants' risk of falling, according to a study. Researchers at the University of Illinois in Urbana-Champaign found that measuring unsteadiness in standing and walking can predict the most common injury among adults 65 and older. Their findings were published Wednesday in npj Digital Medicine. Three million older people are treated in emergency departments for fall injuries each year, according to the Centers for Disease Control and Prevention. That includes at least 300,000 older people hospitalized for hip fractures, of which 95 percent are caused by falling. Older and young people fall for different reasons. Younger people misjudge something, such as a slippery surface, and older adults are unstable, and lose...
Genetic changes in blood may predict leukemia diagnosis

Genetic changes in blood may predict leukemia diagnosis

Health
July 9 (UPI) -- Studying genetic changes in blood, researchers have found a way to identify people at high risk of developing acute myeloid leukemia several years before diagnosis. In the study, published Monday in the journal Nature, researchers from around the world found changes in DNA can reveal the roots of AML in healthy people an average of 6.3 years before symptoms. The researchers hope that methods of reducing the likelihood of developing the cancer will arise with earlier detection and monitoring of those at risk of AML. "Acute myeloid leukemia often appears very suddenly in patients, so we were surprised to discover that its origins are generally detectable more than five years before the disease develops," first author Dr Grace Collord, of the Wellcome Sanger Institute and Un...
Machine learning can predict low blood pressure during surgery

Machine learning can predict low blood pressure during surgery

Health
June 11 (UPI) -- A new algorithm can predict potentially dangerous low blood pressure during surgery. Researchers have developed machine learning than can identify hypotension as much as 15 minutes before it occurs, and are correct about 84 percent of the time. The findings were published Monday in the journal Anesthesiology. "Physicians haven't had a way to predict hypotension during surgery, so they have to be reactive, and treat it immediately without any prior warning," Dr. Maxime Cannesson, a professor of anesthesiology at UCLA Medical Center in Los Angeles, said in a press release. "Being able to predict hypotension would allow physicians to be proactive instead of reactive." Canesson said the tool can save lives -- even with a warning only 10 to 15 minutes ahead of time. "By findi...
