Manipulating fat cells to aid healing without scarring.

PHILADELPHIA – Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells – something that was previously thought to be impossible in humans. Researchers began this work at the Perelman School of Medicine at the University of Pennsylvania, which led to a large-scale, multi-year study in connection with the Plikus Laboratory for Developmental and Regenerative Biology at the University of California, Irvine. They published their findings online in the journal Science on Thursday, January 5^th, 2017.

Fat cells called adipocytes are normally found in the skin, but they’re lost when wounds heal as scars. The most common cells found in healing wounds are myofibroblasts, which were thought to only form a scar. Scar tissue also does not have any hair follicles associated with it, which is another factor that gives it an abnormal appearance from the rest of the skin. Researchers used these characteristics as the basis for their work – changing the already present myofibroblasts into fat cells that do not cause scarring.

If a trip to Venice is your ideal holiday, then you’re going to love the future.

Most of us, however, will be quite sobered by Kim Stanley Robinson’s upcoming novel, New York 2140, a near-future projection of a world reshaped by climate change. Sea level has risen by 50 feet, flooding the Big Apple and countless coastal cities around the planet. Thousands of species have gone extinct.

More evidence to support that excess fat ages the body and is linked with inflammation and senescent cells.

Excess visceral fat tissue is very bad for long-term health. Being obese is by some measures as harmful as a smoking habit when it comes to remaining life expectancy. Even modest amounts of excess weight have a measurable negative impact on the future trajectory of health and longevity. There is an enormous mountain of data to support these points, ranging from large human studies to simple but compelling experiments in which the surgical removal of fat from mice leads to extended life spans. Unfortunately we evolved in an environment of scarcity and so find it a challenge to stay slim in an environment of plenty; this is a high class problem to have in exchange for an end to unavoidable famine and malnutrition, but a problem nonetheless.

One of the contributing causes of degenerative aging is the growing presence of senescent cells in tissues. While investigating the effects of changes in the amount of fat tissue in mice, researchers here find evidence to suggest that some portion of the damage done by fat tissue occurs because it hosts many more senescent cells than would otherwise be present in the body. These cells produce a mix of inflammatory signals, and may well be a sizable cause of the well-known link between visceral fat and increased inflammation. Chronic inflammation alone drives a faster progression of most of the common fatal age-related conditions, and that is without considering all of the other damage done due to the signaling produced by senescent cells.

It’s ten times stronger than steel but is only 5% as dense, and it could revolutionize architecture on Earth, too.

In 1965, Intel co-founder Gordon Moore published a remarkably prescient paper which observed that the number of transistors on an integrated circuit was doubling every two years and predicted that this pace would lead to computers becoming embedded in homes, cars and communication systems.

That simple idea, known today as Moore’s Law, has helped power the digital revolution. As computing performance has become exponentially cheaper and more robust, we have been able to do a lot more with it. Even a basic smartphone today is more powerful than the supercomputers of past generations.

Yet the law has been fraying for years and experts predict that it will soon reach its limits. However, I spoke to Bernie Meyerson, IBM’s Chief Innovation Officer, and he feels strongly that the end of Moore’s Law doesn’t mean the end of progress. Not by a long shot. What we’ll see though is a shift in emphasis from the microchip to the system as a whole.

IBM has unveiled its annual “5 in 5” – a list of ground-breaking innovations that will change the way people work, live, and interact during the next five years.

In 1609, Galileo invented the telescope and saw our cosmos in an entirely new way. He proved the theory that the Earth and other planets in our Solar System revolve around the Sun, which until then was impossible to observe. IBM Research continues this work through the pursuit of new scientific instruments – whether physical devices or advanced software tools – designed to make what’s invisible in our world visible, from the macroscopic level down to the nanoscale.
