AZoRobotics speaks with Dr. Erik Enegberg from Florida Atlantic University about his research into a wearable soft robotic armband. This could be a life-changing device for prosthetic hands users who have long-desired advances in dexterity.
Typing on a keyboard, pressing buttons on a remote control, or braiding a child’s hair has remained elusive for prosthetic hand users. How does the loss of tactile sensations impact limb-absent people’s lives?
Losing the sensation of touch has a profound impact on people’s lives. Some of the things that may seem simple and a part of everyday life, such as stroking the fur of a pet or the skin of a loved one, are a meaningful and fundamental way to connect with those around us for others. For example, a patient with a bilateral amputation has previously expressed concerns that he might hurt his granddaughter by accidentally squeezing her hand too tightly as he has lost tactile sensation.
Framing Alexa’s audio deepfake capabilities as a way to revive a connection to late family members is creepy and weird, even by Amazon’s standards.
Amazon taps emotional woes of pandemic, grief to push developing Alexa feature.

It’s extremely important to check yourself for ticks this summer.
Up to 14.5% of the global population may have already had Lyme disease, according to a new meta-analysis published in BMJ Global Health. The researchers behind the report analyzed 89 previously published studies to calculate the figure, which sheds a harrowing light on the worldwide toll of the tick-borne illness.
From 1991 to 2018, the incidence of Lyme disease in the United States nearly doubled, according to data from the United States Environmental Protection Agency (EPA). In 1991, there were nearly four reported cases per 100,000 people; that number jumped to about seven cases per 100,000 people by 2018. The Centers for Disease Control and Prevention (CDC) estimates that about 470,000 Americans are diagnosed and treated for Lyme disease each year.

Traces of type 2 vaccine-derived poliovirus were detected during routine surveillance of sewage in London.
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia, affecting more than 5.8 million individuals in the U.S. Scientists have discovered some genetic variants that increase the risk for developing Alzheimer’s; the most well-known of these for people over the age of 65 is the APOE ε4 allele. Although the association between APOE4 and increased AD risk is well-established, the mechanisms responsible for the underlying risk in human brain cell types has been unclear until now.
Researchers from Boston University School of Medicine (BUSM) have discovered two important novel aspects of the gene: 1) human genetic background inherited with APOE4 is unique to APOE4 patients and 2) the mechanistic defects due to APOE4 are unique to human cells.
Our study demonstrated what the APOE4 gene does and which brain cells get affected the most in humans by comparing human and mouse models. These are important findings as we can find therapeutics if we understand how and where this risk gene is destroying our brain.
At 79, he’s already outlived the CDC’s official life expectancy by two years and he has no intention of dying — or even slowing down — anytime soon. An active man, Scott jets between his homes in upstate New York and Florida, flies to exotic locations such as Panama City for business and still finds time for the odd cruise. His secret? A DIY regime of self-experimentation and untested therapies he believes will keep him going well past the next century.
Self-experimenters litter the history of medical science. Dentist Horace Wells dosed himself with nitrous oxide in 1,844 to see if it could kill pain, Nicholas Senn inflated his innards with hydrogen a few decades later to work out if it could diagnose a ruptured bowel, and more recently, Barry Marshall drank a solution containing H. pylori in 1985 to prove the bacterium caused ulcers.
These scientists risked their own health to make a medical breakthrough or prove a theory, but Scott is not a scientist. He’s an amateur enthusiast, also known as a biohacker. Biohackers engage in DIY biology, experimenting on themselves to enhance their brain and body. And many of them — like Scott — see longevity as the ultimate prize.
Researchers at the University of Houston are reporting a first-of-its-kind technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known.
Published in The Journal of Cardiovascular Aging 0, the groundbreaking finding has the potential to become a powerful clinical strategy for treating heart disease in humans, according to Robert Schwartz, Hugh Roy and Lillie Cranz Cullen Distinguished Professor of biology and biochemistry at the UH College of Natural Sciences and Mathematics.
The new technology developed by the team of researchers uses synthetic messenger ribonucleic acid (mRNA) to deliver mutated transcription factors — proteins that control the conversion of DNA into RNA — to mouse hearts.

Unfortunately my internet link went down in the second Q&A session at the end and the recording cut off. Shame, loads of great information came out about FPGA/ASIC implementations, AI for the VR/AR, C/C++ and a whole load of other riveting and most interesting techie stuff. But thankfully the main part of the talk was recorded.
Inspired by your liver and activated by light, a chemical process developed in labs at Rice University and in China shows promise for drug design and the development of unique materials.
Researchers led by Rice chemist Julian West and Xi-Sheng Wang at the University of Science and Technology of China, Hefei, are reporting their successful catalytic process to simultaneously add two distinct functional groups to single alkenes, organic molecules drawn from petrochemicals that contain at least one carbon-carbon double bond combined with hydrogen atoms.
Better yet, they say, is that these alkenes are “unactivated”—that is, they lack reactive atoms near the double bond—and until now, have proven challenging to enhance.
