A Bold New Strategy for Stopping the Rise of Superbugs

Posted by in categories: biotech/medical, evolution

Over the past 90 years, scientists have discovered hundreds of antibiotics—microbe-killing drugs that have brought many pernicious diseases to heel. But every time researchers identify a new drug, bacteria inevitably evolve to resist it within a matter of years. We thrust; they parry. Now, with the flow of new antibiotics having dried up for decades, our stalemated duel with infectious bacteria threatens to end in outright defeat. Superbugs are ascendant around the world, including those that resist all commonly used drugs.


Scientists have pinpointed a molecule that accelerates the evolution of drug-resistant microbes. Now they’re trying to find a way to block it.

Human images from world’s first total-body scanner unveiled

Posted by in categories: biotech/medical, entertainment

EXPLORER, the world’s first medical imaging scanner that can capture a 3D picture of the whole human body at once, has produced its first scans.

The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined (PET) and X-ray computed tomography (CT) that can image the entire body at the same time. Because the machine captures radiation far more efficiently than other scanners, EXPLORER can produce an image in as little as one second and, over time, produce movies that can track specially tagged drugs as they move around the entire body.

Next generation of biotech food heading for grocery stores

Posted by in categories: bioengineering, biotech/medical, food, genetics, sustainability

WASHINGTON (AP) — The next generation of biotech food is headed for the grocery aisles, and first up may be salad dressings or granola bars made with soybean oil genetically tweaked to be good for your heart.

By early next year, the first foods from plants or animals that had their DNA “edited” are expected to begin selling. It’s a different technology than today’s controversial “genetically modified” foods, more like faster breeding that promises to boost nutrition, spur crop growth, and make farm animals hardier and fruits and vegetables last longer.

The U.S. National Academy of Sciences has declared gene editing one of the breakthroughs needed to improve food production so the world can feed billions more people amid a changing climate. Yet governments are wrestling with how to regulate this powerful new tool. And after years of confusion and rancor, will shoppers accept gene-edited foods or view them as GMOs in disguise?

Paralyzed individuals successfully use brain waves to operate tablet computers

Posted by in categories: biotech/medical, media & arts, robotics/AI

In a collaborative study presented by scientists primarily affiliated with Stanford and Brown Universities, participants suffering from significant paralysis were successfully able to use non-modified applications on an Android tablet using their brain waves. In previous studies, “point-and-click” computer functionality interpreted from these kinds of signals has been accomplished, but the applications available to participants was limited to software and devices that had been specialized and personalized for users’ specific needs. This study has demonstrated technology that overcomes this limitation and enables access to the full range of software available to non-disabled users. Participants enjoyed applications previously unavailable to them such as streaming music services and a piano keyboard player.

To accomplish the study’s objectives, scientists capitalized and combined existing technologies for their unique end. Brain waves from participants’ brain implants were sent to a commercially available recording system and then processed and decoded by an existing real-time interpreter software. The decoded data was then transmitted to a Bluetooth interface configured as a wireless mouse which was paired to an Android tablet. While the steps to accomplish the task at hand are many, the result somewhat resembles telepathy but largely resembles greater accessibility for the disabled.

Stopping Cancer Cells in Their Tracks

Posted by in category: biotech/medical

Researchers at the University of Minnesota have developed a technique to stop the movement of cancer cells. When cancer moves from a primary tumor to other sites in the body, it becomes far more dangerous to the patient, and that has driven scientists to work for years to learn more about how cancer cells migrate. This work, which was reported in Nature Communications, may help create therapeutics that can prevent cancer from spreading.

After targeting the “motors” that generate forces in cancer cells to move, the cancer cells switch to a dendritic or “flowing” response to follow pathways in tumors that drive cell migration and promote spreading of the cancer. / Credit: Tabdanov/Provenzano, University of Minnesota
