Computer keyboards can be used to detect Parkinson's disease symptoms at home

The Independent - Tech

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display


Computers vs Ebola: Scientists use big data to predict future disease hotspots

#artificialintelligence

A team of scientists have developed a model that can predict the likelihood of bat species carrying Ebola and other filoviruses using a machine learning algorithm. Filoviruses are a group of long filament shaped viruses that encode their genome on a single-stranded RNA. Ebola is the most well-known example; other filoviruses include Marburg disease. Both are lethal viruses that are spread by coming into contact with bodily fluids from an infected person. The last Ebola outbreak happened in 2014 and resulted in 11,310 deaths, according to the World Health Organisation.


New computer program beats physicians at brain cancer diagnoses, could eliminate costly and risky brain biopsies

#artificialintelligence

Computer programs have defeated humans in Jeopardy!, chess and Go. Now a program developed at Case Western Reserve University has outperformed physicians on a more serious matter. The program was nearly twice as accurate as two neuroradiologists in determining whether abnormal tissue seen on magnetic resonance images (MRI) were dead brain cells caused by radiation, called radiation necrosis, or if brain cancer had returned. The direct comparison is part of a feasibility study published in the American Journal of Neuroradiology today. "One of the biggest challenges with the evaluation of brain tumor treatment is distinguishing between the confounding effects of radiation and cancer recurrence," said Pallavi Tiwari, assistant professor of biomedical engineering at Case Western Reserve and leader of the study.


Mount Sinai researchers use computer algorithms to diagnose HCM from echos

#artificialintelligence

Computer algorithms can automatically interpret echocardiographic images and distinguish between pathological hypertrophic cardiomyopathy (HCM) and physiological changes in athletes' hearts, according to research from the Icahn School of Medicine at Mount Sinai (ISMMS), published online yesterday in the Journal of the American College of Cardiology. HCM is a disease in which a portion of the myocardium enlarges, creating functional impairment of the heart. It is the leading cause of sudden death in young athletes. Diagnosing HCM is challenging since athletes can present with physiological hypertrophy, in which their hearts appear large, but do not feature the pathological abnormality of HCM. The current standard of care requires precise phenotyping of the two similar conditions by a highly trained cardiologist.


Brain-Computer Interface Therapy Triggers Some Recovery From Spinal Cord Injury

IEEE Spectrum Robotics

Scientists and engineers led by Duke University neuroscientist Miguel A. Nicolelis report that a group of spinal-cord-injury patients who trained to walk using a brain computer interface (BCI) in combination with an Occulus Rift virtual reality device and with a robotic exoskeleton have regained the ability to voluntarily move their leg muscles and to feel touch and pain in their paralyzed limbs. The study, the results of 12 months of training, is the first long-term BCI experiment to show significant recovery from such severe injuries, the researchers say. The researchers reported their results today in the journal Scientific Reports. A non-invasive electroencephelogram-based brain computer interface was central to the therapies. During the virtual reality excercises, patients were told to imagine walking through a virtual scene.
