Aging fosters sickness and disability, increases human suffering, and makes us more likely to die. Previously, I argued that curing aging must be a top priority for society, yet there are also a number of possible objections to this endeavor. Most of these are unfounded myths that can be disproved while others raise relevant social, philosophical and ethical issues. This essay draws on my own lectures, and publications (Sethe and de Magalhaes, 2013), on this subject and attempts to answer the most commonly raised questions and concerns about the work of gerontologists and a possible cure for aging.

Here’s why you’ll be seeing that word a lot in the future.

Already renowned for its potential to revolutionize everything from light bulbs and dental fillings through to semiconductors and motorcycle helmets, graphene can now add innate superconductivity to its repertoire. Scientists at the University of Cambridge claim to have discovered a method to trigger the superconducting properties of graphene without actually altering its chemical structure.

Light, flexible, and super-strong, the single layer of carbon atoms that makes up graphene has only been rendered superconductive previously by doping it with impurities, or by affixing it to other superconducting materials, both of which may undermine some of its other unique properties.

However, in the latest research conducted at the University of Cambridge, scientists claim to have found a way to activate superconduction in graphene by coupling it with a material known as praseodymium cerium copper oxide (Pr2− xCe xCuO4) or PCCO. PCCO is from a wider class of superconducting materials known as cuprates (derived from the Latin word for copper), known for their use in high-temperature superconductivity.

Chinese researchers hope the tool will help fight cancer.

In Brief The success of this work will help healthcare professionals diagnose more accurately and efficiently, and it will allow for more diagnostic care in areas with limited healthcare services and providers.

In early August, IBM announced that it will acquire Merge Healthcare Inc., a company that sells systems that help medical professionals access and store medical images. This move is a critical step in IBM’s plan to put AI to work medically by training its Watson software to identify maladies like heart disease and cancer.

Merge is valuable to IBM because it owns 30 billion images, including computerized tomography, X-rays, and magnetic-resonance-imaging scans. The company can use these images in its deep learning training program. IBM is hoping that the same kind of software that lets Flickr recognize your face or a dog in your photos can help Watson identify symptoms of diseases.

I am still waiting for mine. I cannot wait to the day I use my smart lenses to take pics, videos, login to view work email, etc. BTW — I look forward to day we eliminate email too.

Google may have shelved Google Glass, its failed attempt to persuade the world that internet-connected spectacles were the next big thing, but it has not given up on the concept of smart eyeware.

A team of engineers has developed a new RNA delivery technique that uses short bursts of ultrasound to efficiently deliver RNA into cells, reducing colon inflammation.

MIT and Brigham and Women’s Hospital researchers have demonstrated that they can deliver strands of RNA efficiently to colon cells, using bursts of ultrasound waves that propel the RNA into the cells. Using this approach, the researchers dramatically turned down the production of a protein involved in inflammatory bowel disease (IBD), in mice.

“What we saw in this paper was the ultrasound can enable rapid delivery of these molecules,” says Carl Schoellhammer, a postdoc at MIT’s Koch Institute for Integrative Cancer Research and the study’s lead author. “In this case it was proinflammatory molecules that we were shutting off, and we saw tremendous knockdown of those proteins.”

(HealthDay)—Eight people who worked at several rat-breeding facilities in Illinois and Wisconsin have been infected with a virus not commonly found in the United States, federal health officials said Friday.

This is the first known outbreak of Seoul virus associated with pet rats in the United States, although there have been several outbreaks in wild rats, according to the federal Centers for Disease Control and Prevention.

(HealthDay)—For patients with unresected anaplastic thyroid carcinoma (ATC), overall survival (OS) is poor, but radiation therapy (RT) dose is associated with improved survival, according to a study published online Dec. 27 in Cancer.

Todd A. Pezzi, from the Baylor College of Medicine in Houston, and colleagues examined the outcomes of patients with unresected ATC who underwent no surgery or grossly incomplete resection. The authors assessed correlates of OS for 1,288 patients.
