A machine learning algorithm can detect signs of anxiety and depression in the speech patterns of young children, potentially providing a fast and easy way of diagnosing conditions that are difficult to spot and often overlooked in young people, according to new research published in the Journal of Biomedical and Health Informatics.

How do you find a virus that's completely unknown? Study says, look to the genome
Viruses, the most abundant biological entities on earth, are a scourge on humanity, causing both chronic infections and global pandemics that can kill millions. Yet, the true extent of viruses that infect humans remains completely unknown. Some newly discovered viruses are recognized because of the sudden appearance of a new disease, such as SARS in 2003, or even HIV/AIDS in the early 1980s. New techniques, however, now enable scientists to identify viruses by directly studying RNA or DNA sequences in genetic material associated with humans, enabling detection of whole populations of viruses—termed the virome—including those that may not cause acutely recognizable disease. However, identifying novel types of viruses is difficult as their genetic sequences may have little in common with already known viral genomes that are available in reference databases.

Study finds biomarker of CTE in some former athletes with multiple concussions
In a group of former professional athletes who experienced multiple concussions, a new study has found that approximately half the group had higher than normal levels of a protein called tau in their cerebrospinal fluid, the fluid surrounding the brain and spine. The study is published in the May 8, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Creating a global map of the protein shape universe
Proteins can provide a detailed look inside the human body and how it protects itself from many diseases. Proteins, which make up about 15% of body mass, are the most abundant solid substances in the human body. They are important working molecules of the immune system, metabolism, brain function, body motion, and any physically and chemically functional parts in a body. Each protein has a specific function under the direction of its own gene.

Research could lead to more precise diagnosis and treatment of ovarian cancer
Oncologists may soon have an accurate and inexpensive way of differentiating between types of ovarian cancer that will improve how patients are treated, thanks to findings from a national research study co-led out of the University of Alberta.

Road test proves adaptive cruise control can add to traffic jam problem
A new, open-road test of adaptive cruise control demonstrated that the feature, designed to make driving easier by continuously adjusting a vehicle's speed in response to the car ahead, doesn't yet solve the problem of phantom traffic jams.

Using AI to predict breast cancer and personalize care
Despite major advances in genetics and modern imaging, the diagnosis catches most breast cancer patients by surprise. For some, it comes too late. Later diagnosis means aggressive treatments, uncertain outcomes, and more medical expenses. As a result, identifying patients has been a central pillar of breast cancer research and effective early detection.

Valve Index will be going high-end in the VR headset world
Pre-orders hovering in the wings will be the icing on the cake—the cake being a high-end VR headset called the Valve Index, from Valve. TechCrunch said pre-orders will kick in and the ship date is June 28. Preorders are for users in the contiguous US and most of Western Europe (the UK is left out for now), said Ars Technica.

Genetic cause identified in familial sarcoidosis
Sarcoidosis is a disease in which nodules of immune cells form, primarily in the lungs but also in the skin or in the heart. While the lung symptoms are similar to those of tuberculosis, the etiology of the disease is unknown. It is currently assumed that causation is multifactorial, whereby certain environmental impacts and bacterial pathogens trigger sarcoidosis in genetically predisposed individuals. For example, there was a rise in the number of cases of sarcoidosis among firemen who were deployed during 9/11, due to the enormous dust burden to which they were exposed. Also, the bacterium responsible for causing acne is found in the pulmonary granulomas of many patients.

Location and brand affect people's trust in cloud services
People's stereotypes regarding different locations around the world influence whether they feel secure in storing their data in cloud service centers in those locations, according to researchers at Penn State, who also found that stereotypes regarding brand authority influence people's trust in cloud services.
