Tapping into the Brain to Help a Paralyzed Man Speak

Posted by in categories: biotech/medical, computing, neuroscience

He has not been able to speak since 2003, when he was paralyzed at age 20 by a severe stroke after a terrible car crash.

Now, in a scientific milestone, researchers have tapped into the speech areas of his brain — allowing him to produce comprehensible words and sentences simply by trying to say them. When the man, known by his nickname, Pancho, tries to speak, electrodes implanted in his brain transmit signals to a computer that displays his intended words on the screen.

His first recognizable sentence, researchers said, was, “My family is outside.”

Customizing Soft Robots in a Universal Way

Posted by in categories: biotech/medical, robotics/AI

What are Soft Robots?

What are Soft Robots?Soft robots are largely made of readily malleable matter, such as fluids, gels, and elastomers, which may match specific materials in a process known as compliance matching. The idea of compliance matching states that materials that make contact with one other should have similar mechanical stiffness in order to transfer internal load uniformly and reduce interfacial tensile stress. This principle, nevertheless, does not applicable to rigid robots (E=109Pa) engaging with soft materials (E=102-106Pa), causing serious damage or mechanical immobility. These kinds of interactions with soft materials are common, for example, with natural skin, muscular tissue, and sensitive interior organs, but also with creatures, artificial predictor variables of biological functions, and so on. Because of this huge disparity in mechanical compliance, it’s simple to assume that stiff robots are unsuitable, if not hazardous, for close human engagement.

Fermented vs. high-fiber diet microbiome study delivers surprising results

Posted by in categories: biotech/medical, food

Investigating the relationship between diet, gut bacteria and systemic inflammation, a team of Stanford University researchers has found just a few weeks of following a diet rich in fermented foods can lead to improvements in microbiome diversity and reductions in inflammatory biomarkers.

The new research pitted a high-fiber diet against a diet with lots of fermented food. Thirty-six healthy adults were recruited and randomly assigned one of the two diets for 10 weeks.

“We wanted to conduct a proof-of-concept study that could test whether microbiota-targeted food could be an avenue for combatting the overwhelming rise in chronic inflammatory diseases,” explains Christopher Gardner, co-senior author on the new study.

A noninvasive test to detect cancer cells and pinpoint their location

Posted by in categories: biotech/medical, computing, engineering, nanotechnology

Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.

MIT engineers have now created a new diagnostic nanoparticle that combines both of these features: It can reveal the presence of cancerous proteins through a urine test, and it functions as an imaging agent, pinpointing the tumor location. In principle, this diagnostic could be used to detect cancer anywhere in the body, including tumors that have metastasized from their original locations.

“This is a really broad sensor intended to respond to both primary tumors and their metastases. It can trigger a urinary signal and also allow us to visualize where the tumors are,” says Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science at MIT and a member of MIT’s Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science.

Genes from tiny viruses can turn bacteria into superbugs

Posted by in categories: biotech/medical, evolution, genetics

Viruses that infect bacteria may drive the evolution of drug-resistant superbugs by inserting their genes into the bacterial DNA, a new study suggests.

The bacteria-attacking viruses, called phages, act as parasites in that they depend on their hosts for survival. The viral parasites often kill off their microbial hosts after infiltrating their DNA, said senior study author Vaughn Cooper, director of the Center for Evolutionary Biology and Medicine at the University of Pittsburgh School of Medicine. But sometimes, the phages slip into the bacterial genome and then lay low, making sneaky changes to the bacterium’s behavior, Cooper said.

Researchers Shocked to Discover Bacterial Parasites Behind Rise of “Superbugs”

Posted by in categories: biotech/medical, evolution, genetics

For the first time ever, researchers from the University of Pittsburgh School of Medicine discovered that phages — tiny viruses that attack bacteria — are key to initiating rapid bacterial evolution leading to the emergence of treatment-resistant “superbugs.” The findings were published today in Science Advances.

The researchers showed that, contrary to a dominant theory in the field of evolutionary microbiology, the process of adaptation and diversification in bacterial colonies doesn’t start from a homogenous clonal population. They were shocked to discover that the cause of much of the early adaptation wasn’t random point mutations. Instead, they found that phages, which we normally think of as bacterial parasites, are what gave the winning strains the evolutionary advantage early on.

“Essentially, a parasite became a weapon,” said senior author Vaughn Cooper, Ph.D., professor of microbiology and molecular genetics at Pitt. “Phages endowed the victors with the means of winning. What killed off more sensitive bugs gave the advantage to others.”
