Mapping molecular neighborhoods

#artificialintelligence

At first glance, it seems counterintuitive. To learn more about how cells go awry causing disease, it seems logical to focus on the minutiae of a cell's molecular components: the specific genes, proteins, and small molecules that change over time leading to a disease state. Instead, Ernest Fraenkel, MIT associate professor in the Department of Biologic Engineering, first takes a macro view for finding new ways to understand and cure diseases. "When you are faced with making any sense of the 10,000 or 20,000 molecules that are present within a cell and evolve during disease, you need an entirely new approach to figure out what is really important among all the changes you see," Fraenkel explains. He develops computational and laboratory experimental methods to uncover the molecular pathways that go awry in disease and search for new strategies and intervention targets.

Medical device innovations: From Sci-Fi movies to the real world

#artificialintelligence

Toya T Peterson speaks on medical devices from the Sci-Fi world that could one day become reality. The handheld medical device used in the popular Star Trek Enterprise might soon become a reality. With Qualcomm having began a contest to see if anyone can create a working tricorder (that weighs less than 5 pounds and fits in the palm!), the healthcare industry might be able to benefit from this great innovation. With the ability to diagnose different conditions (ranging from anemia, diabetes, pneumonia, sleep apnea, and chronic diseases amongst others) and monitor vital signs (like blood pressure, heart rate, temperature and respiratory rate) of patients, the tricorder can be used by patients in the comforts of their homes, without having to visit the doctor. While Ender's Game featured a surgical robot performing brain surgery, robotic medical assistants majorly enable safe patient lifting, reducing incidents of workplace injuries, and hence improved clinician staff retention and satisfaction as well as patient satisfaction.


Twitter CEO Jack Dorsey promotes fitness 'entrepreneur' who claims vaccines cause autism

The Independent - Tech

Twitter chief executive Jack Dorsey has appeared on a podcast with a controversial fitness personality who has promoted scientifically disproven claims that vaccinations cause autism. Host Ben Greenfield – who tweeted in February that "vaccines do indeed cause autism" – thanked Mr Dorsey for an "epic podcast". The Twitter boss responded: "Great conversation and appreciate all you do to simplify the mountains of research focused on increasing one's healthspan! We'll tell you what's true. You can form your own view. His appearance comes as other tech firms like Facebook and Pinterest are cracking down on anti-vaccine content on their platforms. However, Twitter claimed Mr Dorsey was unaware of the host's controversial opinions. A Twitter spokesperson told The Independent that Mr Dorsey did not know about Mr Greenfield's views on vaccinations and that his podcast appearance was not an endorsement of those beliefs.
