Imagine a world where trees light our way at night and branches are antennae. This vision to harness plants as a source of energy has its roots in a groundbreaking study from the Massachusetts Institute of Technology.
'It is important we start to see plants as the starting point of technology. They have these advantages of self-repair and are made of materials that survive harsh environments and have their own water source,'- Researcher Michael Strano
Results on regenerated thymus in very old mice potentially open way for helping humans live longer
Scientists have regenerated a living organ for the first time, potentially opening the way for life-lengthening human therapies.
A team at Edinburgh University’s medical research centre for regenerative medicine managed to rebuild the thymus of very old mice, re-establishing the health of the organ seen in younger creatures.
Scientists reactivated a natural mechanism that shuts down with age to rejuvenate the thymus, an organ near the heart that produces important infection-fighting white blood cells, called T cells.
By targeting a protein called FOXN1, which helps control how genes are switched on, the function of the thymus was restored. Treated mice began to make more T cells.
The research, published in the journal Development, found the thymus grew to twice its previous size, and the recovery appeared sustainable. Scientists now will look into any unintended consequences of increasing FOXN1.
The thymus is the first organ in the human body to deteriorate as we age, contributing to the declining capacity of older people to fight off new infections, such as flu.
The breakthrough may lead to treatments that could significantly elongate human life. But this would be many years away, given that the process has been tested only on mice.
Appearing by telepresence robot, Edward Snowden speaks at TED2014 about surveillance and Internet freedom. The right to data privacy, he suggests, is not a partisan issue, but requires a fundamental rethink of the role of the internet in our lives — and the laws that protect it. "Your rights matter,” he says, "because you never know when you're going to need them." Chris Anderson interviews, with special guest Tim Berners-Lee.
And you thought managing a smartphone and an inbox was exhausting.
45-year-old Chris Dancy is known as the most connected man in the world. He has between 300 and 700 systems running at any given time, systems that capture real-time data about his life.
His wrists are covered with a variety of wearable technology, including the fitness wristband tracker Fitbit and the Pebble smartwatch. He weighs himself on the Aria Wi-Fi scale, uses smartphone controlled Hue lighting at home and sleeps on a Beddit mattress cover to track his sleep.
Craig Venter, who managed to make science both lucrative and glamorous with his pioneering approach to gene sequencing and synthetic biology, is taking on a new venture: aging.
He has joined forces with the founder of the X Prize and an expert in cell therapy to launch on Tuesday a new company called Human Longevity Inc. The man who once took off on his personal yacht to sample all the microscopic life in the seas plans to leverage some of the most fashionable new scientific approaches to figure out what makes us sick and old.
The San Diego-based company will tackle aging using gene sequencing; stem cell approaches; the collection of bacteria and other life forms that live in and on us called the microbiome; and the metabolome, which includes the byproducts of life called metabolites.
They’ll start out with what they are calling the largest human sequencing operation in the world.
“We are building a lab to a scale never attempted (before),” Venter told NBC News.
Venter first shot to fame when he raced with government scientists to finish the first map of all human DNA, called the human genome. Venter, himself a former government scientist, annoyed his former colleagues with a brash new approach to gene sequencing that was much faster but far less accurate, in their opinion.
As we discover more about love's neural basis, we are getting closer to a pill to diminish heartbreak
ROSES are red, violets are blue, when you reject me, what can I do? As we discover more about love's neural basis, we are getting closer to a way of curing its ills.
While many might be wary of a chemical cure for heartbreak, there is an argument that such anti-love solutions could help people struggling with suicidal or delusional thoughts because of unrequited love, or those in the clutches of unrelenting grief. The morals of the use and misuse of such drugs are complex (see "Cure for love: Should we take anti-love drugs?"), but ethics aside, what could a cure for love look like?
First things first: what is love? For Shakespeare, it "is an ever-fixed mark, that looks on tempests and is never shaken". For neuroscientists, it's less poetic: a neurobiological phenomenon that falls into three subtypes: lust, attraction and attachment – all of which increase our reproductive and parental success.
Each aspect is grounded in a suite of overlapping chemical systems in the brain. There are ways to diminish each of them, says Helen Fisher at Rutgers University in New Jersey, but they aren't always palatable.
Take lust. Ever found yourself obsessing over the tiniest details of a person? Their hair, say, or the number of kisses in a text? This tunnel vision resembles some of the symptoms of obsessive compulsive disorder, so Donatella Marazziti at the University of Pisa in Italy, compared the brains of 20 people in the first throes of love with those of 20 people with OCD.
Both groups had unusually low levels of a protein that transports serotonin – a hormone involved in regulating mood – around the brain. Retesting the lovers a year later revealed that their serotonin levels had increased, and that they no longer reported an obsessive focus on their partners.
A new study out of Pew Research Center shows how Americans view the future of tech and what they're not quite ready for.
Americans are hopeful about the future of technology. But don’t release the drones just yet. And forget meat grown in a petri dish.
Pushing new tech on a public that isn’t ready can have real bottom-line consequences.
That’s the takeaway from a new study released by the Pew Research Center looking at how U.S. residents felt about possible high-tech advances looming in the not-too-distant future. Overall, a decisive majority of those surveyed believed new tech would make the future better. At the same time, the public doesn’t seem quite ready for many of the advances companies like Google and Amazon are pushing hard to make real.
If the stigma surrounding Google Glass (or, perhaps more specifically, “Glassholes”) has taught us anything, it’s that no matter how revolutionary technology may be, ultimately its success or failure ride on public perception. Many promising technological developments have died because they were ahead of their times. During a cultural moment when the alleged arrogance of some tech companies is creating a serious image problem, the risk of pushing new tech on a public that isn’t ready could have real bottom-line consequences.
(Phys.org) —An extremely tiny lensless camera, developed by Rambus, has been slowly making waves over the past year. Researchers for the company, David Stork and Patrick Gill won a Best Paper award at last year's Sencomm 2013 for describing what the company has created. They spoke again at last month's ...
We live in an era of accelerating change, when scientific and technological advancements are arriving rapidly. As a result, we are developing a new language to describe our civilization as it evolves. Here are 20 terms and concepts that you'll need to navigate our future.
Across the planet, new technologies and business models are decentralizing power and placing it in the hands of communities and individuals. "We are seeing technology-driven networks replacing bureacratically-driven hierarchies," says VC and futurist Fred Wilson, speaking on what to expect in the next ten years.
