Soft wearable health monitor uses stretchable electronics

Posted by in categories: biotech/medical, computing, engineering, health, mobile phones, wearables

A wireless, wearable monitor built with stretchable electronics could allow comfortable, long-term health monitoring of adults, babies and small children without concern for skin injury or allergic reactions caused by conventional adhesive sensors with conductive gels.

The soft and conformable monitor can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data as much as 15 meters to a portable recording device such as a smartphone or tablet computer. The electronics are mounted on a stretchable substrate and connected to gold, -like electrodes through printed connectors that can stretch with the medical film in which they are embedded.

“This health monitor has a key advantage for young children who are always moving, since the soft conformal device can accommodate that activity with a gentle integration onto the skin,” said Woon-Hong Yeo, an assistant professor in the George Woodruff School of Mechanical Engineering and Wallace H. Coulter Department of Biomedical Engineering at the Georgia Institute of Technology. “This is designed to meet the electronic health monitoring needs of people whose sensitive skin may be harmed by conventional monitors.”

First pictures of enzyme that drives new class of antibiotics

Posted by in category: biotech/medical

Understanding how antibiotic scaffolds are constructed in nature can help scientists prospect for new classes of antibiotics through DNA sequencing and genome mining. Researchers have used this knowledge to help solve the X-ray crystal structure of the enzyme that makes obafluorin—a broad spectrum antibiotic agent made by a fluorescent strain of soil bacteria. The new work from Washington University in St. Louis and the University at Buffalo is published July 31 in the journal Nature Communications.

A multi-part called a nonribosomal peptide synthetase produces the highly reactive beta-lactone ring that is responsible for obafluorin’s antimicrobial activity.

“Obafluorin has a novel structure compared to all FDA-approved antibiotics,” said Timothy Wencewicz, assistant professor of chemistry in Arts & Sciences. “In the long term, we really need new structural classes of antibiotics that have never been contaminated by clinical resistance from established antibiotic classes.”

Newly Identified Cell May Be Able to Regenerate Liver Tissue

Posted by in categories: biotech/medical, health

According to Public Health England, l iver disease is a devastating all too common condition. It is the fifth biggest killer in the UK and the third most common cause of premature death and it is on the rise.

Regenerating liver tissue

Now, researchers at King’s College London may have found a solution to this disease. The scientists have used single cell RNA sequencing to identify a type of cell that may be able to effectively regenerate liver tissue.

Human placenta has no microbiome but can contain potential pathogens

Posted by in category: biotech/medical

We sought to determine whether pre-eclampsia, spontaneous preterm birth or the delivery of infants who are small for gestational age were associated with the presence of bacterial DNA in the human placenta. Here we show that there was no evidence for the presence of bacteria in the large majority of placental samples, from both complicated and uncomplicated pregnancies. Almost all signals were related either to the acquisition of bacteria during labour and delivery, or to contamination of laboratory reagents with bacterial DNA. The exception was Streptococcus agalactiae (group B Streptococcus), for which non-contaminant signals were detected in approximately 5% of samples collected before the onset of labour. We conclude that bacterial infection of the placenta is not a common cause of adverse pregnancy outcome and that the human placenta does not have a microbiome, but it does represent a potential site of perinatal acquisition of S. agalactiae, a major cause of neonatal sepsis.

A technique called Hybrid 3D Printing, developed by AFRL researchers in collaboration with the Wyss Institute at Harvard University, uses additive manufacturing to integrate soft, conductive inks with material substrates to create stretchable electronic devices. A potential application is to create sensors to enable better human performance monitoring. (Courtesy photo/Harvard Wyss Institute)…/afrl-harvard-researchers-invent…/

Years and Years’ transhumanist character Bethany shows the conundrum of merging human and machine

Posted by in categories: biotech/medical, internet, life extension, transhumanism

In the premiere of the HBO/BBC miniseries Years and Years, two parents are worried. Their teenage daughter Bethany has been hiding behind a 3D animated emoji mask and has scheduled a talk with them. Trying to figure out what they’re up against, they sneak a peek at her internet searches. When they discover that she’s been searching for information about being trans, they’re relieved; they can handle a transgender child.

Except when it comes time for their talk, Bethany tells her parents she’s transhuman and that she wants to “live forever as information.” The show represents transhumanist technology and aspirations, many of which revolve around upgrading and digitizing the human body, as a movement that will bring positive, negative, and downright confusing implications, ultimately changing the human race. The real question is what exactly that means. Humans opened the Pandora’s box of merging technology and biology a long time ago, and we’re now speeding head-on into the consequences, despite not knowing what humanity will become.

Bethany’s “coming out” scene hinges on the fact that the changes she desires are far more dangerous—and, for her parents, far more difficult to stomach—than gender reassignment. Bethany’s excitement at escaping the mortal coil brims with typical teenage naïveté: “Transhumans are not male or female, but better,” she tells her parents. For Bethany, that means no longer being human. “I will be data!” she enthuses.

Scientists Create Miniature Sun in Wisconsin

Posted by in categories: robotics/AI, space

The sun is easy to spot in the sky, and it’s not very far away in astronomical terms. So, scientists have spent a great deal of time studying our local life-giving star. However, the sun is also a nuclear inferno that will eradicate any people and most robots that get too close. To study the star up close, researchers at the University of Wisconsin-Madison built a miniature sun. They call it the Big Red Ball (BRB), and it could help us understand some fundamental solar processes.

Like most main sequence stars, the sun is a giant ball of hydrogen massive enough to sustain a nuclear fusion reaction. The hydrogen fuses into helium, and helium eventually fuses into heavier elements as stars exhaust their fuel. The sun still has plenty of life left, so it’s mostly hydrogen with about one-quarter helium.

The BRB uses helium to create analogous conditions to those on the sun, but without all that pesky nuclear fusion. As experiments have shown, it’s extremely difficult to maintain nuclear fusion on Earth. The BRB is a hollow sphere almost ten feet (three meters) in diameter. The team filled that space with helium gas (which again is a major component of the sun) and ionized it with microwave heating to form a sun-like plasma. Powerful magnets confine the plasma, and an electrical current causes the miniature sun to spin a bit like the real one.
