Blood serum study reveals networks of proteins that impact aging

Posted by in categories: biotech/medical, computing, life extension

A team of researchers from several institutions in Iceland and the U.S. has conducted a unique blood serum investigation and discovered multiple protein networks that are involved in the aging process. In their paper published in the journal Science, the group describes their study and what they found.

Prior research has shown that when older mice have their blood systems connected to younger mice, the older mice experience improvements in age-related organ deterioration. This finding has led scientists to suspect that aging might be caused by something in the blood. In this new effort, the researchers sought to test this idea by studying proteins in the circulatory system.

The study consisted of analyzing blood samples from 5,457 people living in Iceland, all of whom were over the age of 65 and who were participants in an ongoing study called Age, Gene/Environment Susceptibility. The volunteers had also been chosen specifically to represent a cross section of the people living in Iceland. The major part of the analysis involved creating a panel of DNA aptamers (short sequences that bind to proteins) that could be used to recognize proteins, both known and unknown. Blood serum from the volunteers was then compared against the panels and the results were analyzed by a computer looking for patterns.

Soft, multi-functional robots get really small

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

Roboticists are envisioning a future in which soft, animal-inspired robots can be safely deployed in difficult-to-access environments, such as inside the human body or in spaces that are too dangerous for humans to work, in which rigid robots cannot currently be used. Centimeter-sized soft robots have been created, but thus far it has not been possible to fabricate multifunctional flexible robots that can move and operate at smaller size scales.

A team of researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering, Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), and Boston University now has overcome this challenge by developing an integrated fabrication process that enables the design of on the millimeter scale with micrometer-scale features. To demonstrate the capabilities of their new technology, they created a robotic soft spider – inspired by the millimeter-sized colorful Australian peacock spider – from a single elastic material with body-shaping, motion, and color features. The study is published in Advanced Materials.

“The smallest soft robotic systems still tend to be very simple, with usually only one degree of freedom, which means that they can only actuate one particular change in shape or type of movement,” said Sheila Russo, Ph.D., co-author of the study. Russo helped initiate the project as a Postdoctoral Fellow in Robert Wood’s group at the Wyss Institute and SEAS and now is Assistant Professor at Boston University. “By developing a new hybrid technology that merges three different fabrication techniques, we created a soft robotic spider made only of silicone rubber with 18 degrees of freedom, encompassing changes in structure, motion, and color, and with tiny features in the micrometer range.”

New class of drug compounds puts cancer in a sleeper hold

Posted by in category: biotech/medical

Cancer isn’t some foreign illness invading your body – it’s essentially just regular cells dividing out of control. Current cancer treatments like chemotherapy and radiotherapy are designed to kill tumors, but they often take down healthy cells as well. An emerging technique could provide a more targeted approach, stopping tumorous cells from proliferating and effectively putting the cancer to sleep.

Lyme disease now found in all 50 states

Posted by in category: biotech/medical

If you thought you were safe from Lyme disease because you don’t live in New England, where the tick-borne illness first appeared, think again. Now, all 50 states plus the District of Columbia have residents who have tested positive for Lyme, a bacterial infection that can cause a wide variety of symptoms, including joint aches, fatigue, facial palsy and neck stiffness.

This news comes from a report from the clinical laboratory Quest Diagnostics, which analyzed the results of 6 million blood tests doctors had ordered to diagnose Lyme disease in their patients. The report found that Pennsylvania had the most positive cases last year: 10,001.

The Pennsylvania tally, along with that of the six New England states — Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont — accounted for about 60 percent of the country’s Lyme disease cases. Positive results grew by 50 percent in New England and by 78 percent in Pennsylvania from 2016 to 2017.

New system allows rapid response to heart attacks, limits cardiac damage

Posted by in categories: biotech/medical, engineering, health

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a drug-delivery system that allows rapid response to heart attacks without surgical intervention. In laboratory and animal testing, the system proved to be effective at dissolving clots, limiting long-term scarring to heart tissue and preserving more of the heart’s normal function.

“Our approach would allow health-care providers to begin treating heart attacks before a patient reaches a surgical suite, hopefully improving patient outcomes,” says Ashley Brown, corresponding author of a paper on the work and an assistant professor in the Joint Biomedical Engineering Program (BME) at NC State and UNC. “And because we are able to target the blockage, we are able to use powerful drugs that may pose threats to other parts of the body; the targeting reduces the risk of unintended harms.”

Heart attacks, or myocardial infarctions, occur when a thrombus – or clot – blocks a blood vessel in the heart. In order to treat heart attacks, doctors often perform surgery to introduce a catheter to the blood vessel, allowing them to physically break up or remove the thrombus. But not all patients have quick access to surgical care.

Beyond the Hard Drive: Encoding Data in DNA

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

This article is part of a series about how OS Fund (OSF) companies are radically redefining our future by rewriting the operating systems of life. Or as we prefer to think about it: Step 1: Put a dent into the universe. And Step 2: Rewrite the universe. You can see the full OSF collection here and read more about Building a Biological Immune System.

In contemplating the future, I love imagining how our daily lives today will be thought of in the future. What appears sci-fi to us today but will be “normal” 50 years from now? What inefficient and boneheaded things do we do today that future generations will look back and laugh at?

Employees at Google, Amazon and Microsoft Have Threatened to Walk Off the Job Over the Use of AI

Posted by in categories: biotech/medical, ethics, information science, military, robotics/AI

There is. Our engagement with AI will transform us. Technology always does, even while we are busy using it to reinvent our world. The introduction of the machine gun by Richard Gatling during America’s Civil War, and its massive role in World War I, obliterated our ideas of military gallantry and chivalry and emblazoned in our minds Wilfred Owen’s imagery of young men who “die as Cattle.” The computer revolution beginning after World War II ushered in a way of understanding and talking about the mind in terms of hardware, wiring and rewiring that still dominates neurology. How will AI change us? How has it changed us already? For example, what does reliance on navigational aids like Waze do to our sense of adventure? What happens to our ability to make everyday practical judgments when so many of these judgments—in areas as diverse as credit worthiness, human resources, sentencing, police force allocation—are outsourced to algorithms? If our ability to make good moral judgments depends on actually making them—on developing, through practice and habit, what Aristotle called “practical wisdom”—what happens when we lose the habit? What becomes of our capacity for patience when more and more of our trivial interests and requests are predicted and immediately met by artificially intelligent assistants like Siri and Alexa? Does a child who interacts imperiously with these assistants take that habit of imperious interaction to other aspects of her life? It’s hard to know how exactly AI will alter us. Our concerns about the fairness and safety of the technology are more concrete and easier to grasp. But the abstract, philosophical question of how AI will impact what it means to be human is more fundamental and cannot be overlooked. The engineers are right to worry. But the stakes are higher than they think.
