MIT researchers have developed PIGINet, a new system that aims to efficiently enhance the problem-solving capabilities of household robots, reducing planning time by 50–80 percent.

This is according to a press release by the institution published on Friday.

Under normal conditions, household robots follow predefined recipes for performing tasks, which isn’t always suitable for diverse or changing environments. PIGINet, as described by MIT, is a neural network that takes in “Plans, Images, Goal, and Initial facts,” then predicts the probability that a task plan can be refined to find feasible motion plans.

Summary: Psychologists revealed people’s judgments of truthfulness are influenced by what they perceive as the information source’s intentions.

They found that even when individuals knew the factual accuracy of a claim, their judgment of its truth was affected by whether they thought the source was trying to deceive or inform them. This tendency held true for both politicized and non-politicized topics.

This research uncovers a new facet of truth perception, showing that objective accuracy is not the only criterion considered.

Sir Frederick Banting was clearly ahead of his time. He is also an inspiration for a new open source self-administering drug delivery device. Long before open source was an option or even a concept, the now-celebrated former Western lecturer refused to patent insulin because he wanted it to be inexpensive and widely available for the betterment of all.

Now, 100 years after Banting won the Nobel Prize for his discovery, Western researchers are at it again. A team led by engineering and Ivey Business School professor Joshua Pearce has developed a new 3D printed, completely open-source autoinjector —a device designed to deliver a single dose of medicine—for a tenth of the cost of a commercially purchased product.

McMaster researchers have uncovered a fast and effective way to detect cancer stem cells before the disease recurs in adults who previously underwent treatment.

Singapore: A research paper, published in iScience, has decribed the development of a deep learning model for predicting hip fractures on pelvic radiographs (Xrays), even with the presence of metallic implants.

Yet Yen Yan of Changi General Hospital and colleagues at the Duke-NUS Medical School, Singapore, and colleagues developed the AI (artificial intelligence) algorithm using more than fortythousand pelvic radiographs from a single institution. The model demonstrated high specificity and sensitivity when applied to a test set of emergency department (ED) radiographs.

This study approximates the realworld application of a deep learning fracture detection model by including radiographs with suboptimal image quality, other nonhip fractures and meta llic implants, which were excluded from prior published work. The research team also explored the effect of ethnicity on model performance, and the accuracy of visualization algorithm for fracture localization.

Sweden: A recent study published in the journal Circulation has revealed a link between the levels of certain bacteria living in the gut and coronary atherosclerotic plaques. The Swedish study was led by researchers at Uppsala and Lund University.

Atherosclerotic plaques are formed by the build-up of fatty and cholesterol deposits and constitute a major cause of heart attacks.

The new study was based on analyses of gut bacteria and cardiac imaging among 8,973 participants aged 50 to 65 from Uppsala and Malmö without previously known heart disease. They were all participants in the Swedish CArdioPulmonary bioImage Study (SCAPIS).

Scientists have used CRISPR gene editing to reduce the lignin content in poplar trees by as much as 50%, offering a potentially more sustainable and efficient method of fibre production.

Lignin is a complex organic polymer that is integral to the structure of cell walls in many types of plants, especially in wood and bark. It acts as a type of binder in these walls, giving wood its hardness and resistance to rot. Lignin is the second most abundant natural polymer in the world, next to cellulose, and makes up between 15% and 25% of the composition of wood.

Science and Technology:

Hope that they find a medicine to cure aging and turn us immortal and able to live forever still during “our” lifetime.

Insilico Medicine, a clinical stage generative artificial intelligence (AI)-driven drug discovery company, today announced that it combined two rapidly developing technologies, quantum computing and generative AI, to explore lead candidate discovery in drug development and successfully demonstrated the potential advantages of quantum generative adversarial networks in generative chemistry.
