Part of Vittorio Sebastiano’s job is to babysit a few million stem cells. The research professor of reproductive biology at Stanford University keeps the cells warm and moist deep inside the Lorry I. Lokey Stem Cell Research Building, one of the nation’s largest stem cell facilities. He’s joined there by an army of researchers, each with their own goals. His own research program is nothing if not ambitious: He wants to reverse aging in humans.
Stem cells are the Gary Oldman of cell types. They can reprogram themselves to carry out the function of virtually any other type of cell, and play a vital role in early development. This functional reprogramming is usually accompanied by an age reset, down to zero. Sebastiano figures that if he can separate these different kinds of reprogramming, he can open up a whole new kind of aging therapy. Nautilus caught up with him last month.

Researcher Dr. Dena Dubal, from the University of California San Francisco, is considering a new approach to combat neurodegenerative diseases, such as Alzheimer’s disease and dementia, using a protein known as klotho.
Aging is the foundation of age-related diseases
Instead of trying to understand each of these diseases and the complex mechanisms unique to both, she considered what all these conditions have in common; the answer, of course, is aging.

A tiny (one-centimeter-square) biosensor chip developed at EPFL is designed to be implanted under your skin to continuously monitor concentrations of pH, temperature, and metabolism-related molecules like glucose, lactate and cholesterol, as well as some drugs.
The chip would replace blood work, which may take hours — or even days — for analysis and is a limited snapshot of conditions at the moment the blood is drawn.

Will the benefits of making data more widely available outweigh such risks? The signs are that they will. Plenty of countries are now opening up their medical records, but few have gone as far as Sweden. It aims to give all its citizens electronic access to their medical records by 2020; over a third of Swedes have already set up accounts. Studies show that patients with such access have a better understanding of their illnesses, and that their treatment is more successful. Trials in America and Canada have produced not just happier patients but lower costs, as clinicians fielded fewer inquiries. That should be no surprise. No one has a greater interest in your health than you do. Trust in Doctor You.
NO WONDER they are called “patients”. When people enter the health-care systems of rich countries today, they know what they will get: prodding doctors, endless tests, baffling jargon, rising costs and, above all, long waits. Some stoicism will always be needed, because health care is complex and diligence matters. But frustration is boiling over. This week three of the biggest names in American business—Amazon, Berkshire Hathaway and JPMorgan Chase—announced a new venture to provide better, cheaper health care for their employees. A fundamental problem with today’s system is that patients lack knowledge and control. Access to data can bestow both.
The internet already enables patients to seek online consultations when and where it suits them. You can take over-the-counter tests to analyse your blood, sequence your genome and check on the bacteria in your gut. Yet radical change demands a shift in emphasis, from providers to patients and from doctors to data. That shift is happening. Technologies such as the smartphone allow people to monitor their own health. The possibilities multiply when you add the crucial missing ingredients—access to your own medical records and the ability easily to share information with those you trust. That allows you to reduce inefficiencies in your own treatment and also to provide data to help train medical algorithms. You can enhance your own care and everyone else’s, too.

Using a new technique they call “in-air microfluidics,” University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and ‘on-the-fly’ production of micro building blocks that are viable and can be used for repairing damaged tissue, for example. The work is presented in Science Advances.
Microfluidics is all about manipulating tiny drops of fluid with sizes between a micrometer and a millimeter. Most often, chips with tiny fluidic channels, reactors and other components are used for this: lab-on-a-chip systems. Although these chips offer a broad range of possibilities, in producing emulsions for example—droplets carrying another substance – the speed at which droplets leave the chip is typically in the microliter per minute range. For clinical and industrial applications, this is not fast enough: filling a volume of a cubic centimeter would take about 1000 minutes or 17 hours. The technique that is presented now, does this in a couple of minutes.

Summary: Activating T cells in tumors destroyed most traces of cancer in mice, and had ‘amazing, bodywide effects,’ Stanford University researchers reported. The researchers are recruiting lymphoma patients to test the approach in a clinical trial. [This article first appeared on the website LongevityFacts.com. Author: Brady Hartman. ]
Researchers at the Stanford University School of Medicine used two novel agents to activate immune system T cells in tumors. The immune-boosting treatment destroyed most traces of cancer in mice the researchers reported in a study published on Jan. 31 in the journal Science Translational Medicine.
Injecting tiny amounts of two immune-stimulating agents directly into solid tumors in mice can eradicate all traces of cancer in the rodents, including distant metastases, the researchers found. The novel approach works for many different types of cancers, including tumors that arise spontaneously, the new study found.
