No more ‘superbugs’? Maple syrup extract enhances antibiotic action

Posted by in categories: biotech/medical, health

SAN FRANCISCO, April 2, 2017 — Antibiotics save lives every day, but there is a downside to their ubiquity. High doses can kill healthy cells along with infection-causing bacteria, while also spurring the creation of “superbugs” that no longer respond to known antibiotics. Now, researchers may have found a natural way to cut down on antibiotic use without sacrificing health: a maple syrup extract that dramatically increases the potency of these medicines.

The researchers will present their work today at the 253rd National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world’s largest scientific society, is holding the meeting here through Thursday. It features more than 14,000 presentations on a wide range of science topics.

“Native populations in Canada have long used maple syrup to fight infections,” says Nathalie Tufenkji, Ph.D. “I’ve always been interested in the science behind these folk medicines.”

Customized babies are closer than you think

Posted by in categories: biotech/medical, economics, genetics, health, policy

The race is on to edit genes and prevent disease. But this technology is ripe for abuse.

Economic inequity already exists in the reproductive industry. IVF, for example, is not covered by insurance in most states (Massachusetts excepted), setting up a situation in which only infertile people with well-padded pockets can afford the treatment. And of course the well-off have easier access to good health care via quality private insurance — or their own bank accounts. Steve Jobs, for example, spent $100,000 in 2011 to sequence his genome and that of his pancreatic tumor — a bill not many could hope to afford.

“The beautiful thing about this [gene-editing] work is it offers an opportunity to intervene around the moment of birth,” says Katy Kozhimannil, an associate professor in the Division of Health Policy at University of Minnesota’s School of Public Health. “That said, as we pay attention to the opportunity of that moment, it’s important to bear in mind the value of liberty and justice for all.”

People afraid of robots much more likely to fear losing their jobs, suffer anxiety

Posted by in categories: health, robotics/AI

“Technophobes”—people who fear robots, artificial intelligence and new technology that they don’t understand—are much more likely to be afraid of losing their jobs to technology and to suffer anxiety-related mental health issues, a Baylor University study found.

More than a third of those in the study fit its definition of “technophobe” and are more fearful of automation that could lead to job displacement than they are of potentially threatening or dangerous circumstances such as romantic rejection, public speaking and police brutality, according to the study.

“If you’re afraid of losing your job to a robot, you’re not alone,” said researcher Paul McClure, a sociologist in Baylor’s College of Arts & Sciences. “This is a real concern among a substantial portion of the American population. They are not simply a subgroup of generally fearful people.”

Scientists just changed the way we build genomes to make them 270,000 times cheaper

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

In 2003, the US Department of Defense and the National Institutes of Health announced that—13 years and $2.7 billion later—they had finally finished mapping the human genome.

But the quest to understand human genetics was far from over: Genomes, which are the entire layout of our 3 billion base pairs of DNA, vary dramatically from person to person. So mapping the first human genome was really just mapping a human genome (the patient’s identity was kept secret for privacy.) And even though shorter genetic sequencing is available, doctors studying rare genetic diseases need the full scope of a patient’s genetic material to find the problematic mutation. Finding these faulty sections of genes is like a microscopic version of Where’s Waldo among 3 billion people wearing stripes, a game that has cost $3 billion to play.

In a paper published (paywall) in Science on March 23, researchers from the Baylor College of Medicine, Massachusetts Institute of Technology, and Harvard University said they have figured a way to sequence the entirety of any genome for just $10,000, in a couple of weeks. Their test project? Re-sequencing the DNA of the mosquito species that spreads the Zika virus.

Why Mary Lou Jepsen Left Facebook: To Transform Health Care and Invent Consumer Telepathy

Posted by in categories: biotech/medical, health, mathematics, neuroscience, wearables

“Yep, transforming health care and telepathy, those are the items on her to-do list. Jepsen plans to achieve both goals with a cheap wearable device that her engineers are now tinkering with in the lab. And then there’s the side benefit of reinvigorating the tired consumer electronics industry, which Jepsen thinks is due for the next big thing.

Jepsen was at SXSW to give a talk about Openwater, her new startup. While the company is still conducting R&D to decide on its first products, Jepsen feels the need to speak out now about what she’s building and how she thinks her technology could radically change society. She wants to give people fair warning and time to think about what’s coming. “I know it seems outlandish to be talking about telepathy, but it’s completely solid physics and mathematical principles—it’s in reach in the next three years,” she says.

Plus, she’s sick of stealth mode. “I haven’t been able to to talk about what I’ve been doing for five and half years while I was at Google and Facebook, and I don’t think secrecy is useful,” she says. She left Facebook in August, and in September she filed patents for her Openwater technology, which she expects to be issued any day now.

Considering IBM’s Goals in Bringing Watson to the Cancer Fight

Posted by in categories: biotech/medical, health

IBM (IBM) has begun the deeper deployment of Watson to help fight cancer. Last month, the company announced a partnership with Jupiter Medical Center in Florida to enable oncologists to tap into Watson’s cancer knowledge to make the best cancer treatment decisions.

The deal with Jupiter marked the first step in bringing Watson to the fight against cancer at a US (SPY) community health facility.

Hacking the Human Brain—New Tech Could Make It a Reality

Posted by in categories: food, government, health, military, mobile phones, neuroscience

In Brief

  • Your thoughts are your own, right? Perhaps not. New technology is bringing that day closer when the unscrupulous may actually be able to hack human thoughts.
  • It raises a number of new ethical concerns for this brave new world we’re entering with each rotation of the Earth.

Everyone is familiar with the concept of hacking. It is why we all strive to protect our computers and smartphones from nefarious outside sources trying to break in to steal information, implant malware, etc. Hackers pose a threat to everyone from teenage smartphone users to the computer databases of government organizations. Hacking is a threat that we are all familiar with, and something that many know how to protect against. But, as the line between science and science fiction blurs, even hacking is getting a futuristic upgrade. Recently, at the Enigma Security Conference, University of Washington researcher and lecturer Tamara Bonaci revealed technology that could be used to essentially “hack” into people’s brains.

She created this technology around a game called Flappy Whale. While people played the game, the technology was able to covertly extract neural responses to subliminal imagery in the game like logos, restaurants, cars, etc. Now, hacking into people’s underlying feelings and thoughts about seeing a fast food restaurant doesn’t seem like it could cause much harm, but this technology has the potential to gather much more intimate information about a person like their religion, fears, prejudices, health, etc. This technology could evolve from an interesting way to understand human response to a military device. The possibilities range from an incredibly useful research tool to a potentially frightening interrogation device.

Biotech’s 3D Breakthrough

Posted by in categories: 3D printing, bioprinting, biotech/medical, health

Every day in a San Diego lab, raw material derived from donated tissue unsuitable for organ transplantation goes into a machine, and three-dimensional human liver tissue is printed out.

Pioneered by a company called Organovo, this 3D bioprinting technology may one day achieve the Holy Grail of its industry: the manufacturing of whole human organs to replace damaged ones. But for now, it’s already making an impact on human health, as pharmaceutical and biotech companies are using its manufactured human liver tissue to test the toxicity of new drugs and therapies.

Organovo is developing multiple tissue types for therapeutic use, with strong early results in animal models. In three to five years, there’s a good chance that it will have an Investigational New Drug Application in at least one tissue. The company’s strategic plan is coming to fruition just as its chief scientific officer, Sharon Presnell, envisioned when she joined the startup in 2011.
