Scientists have discovered a central hub of brain cells that may put the brakes on a desire to eat, a study in mice shows.
And switching on these neurons can stop feeding immediately, according to the Nature Neurosciences report.
Researchers say the findings may one day contribute to therapies for obesity and anorexia.
Experts say this sheds light on the many complex nerve circuits involved in appetite control.

Deep brain stimulation as a treatment for epilepsy and movement disorders, most notably Parkinson’s disease, has rapidly gone from experimental to standard practice. With devices to provide delicate electro-stimulation to the brain now available and with maps of which neurons do what steadily gaining detail, attention is now shifting to using the approach to treat mental illness.

Violence is contagious, this we know. Time and again, researchers have found that exposure to aggression links directly to increases in violent behavior. This is why, for example, 30% of abused children grow up to be abusers themselves. It’s also why, as Gary Slutkin, a professor of epidemiology and public health at the University of Illinois, Chicago and the executive director of CURE Violence, recently told New Scientist: “[P]eople who have observed violence are 30 times more likely to commit it. Under certain conditions it can be up to 100 to 1,000 times more likely.”

It turns out that an apple a day — or at least an apple spinach salad — does keep the doctor away. But it’s not true that when brain cells die we can’t make more. When and how remain active questions, however, so there’s no free pass to collectively disregard our mothers’ safety tips just yet.
Researchers at Duke University have shed some light on the subject with findings that suggest that down the line doctors may be able spur the brain to repair itself.
Uploading the content of one’s mind, including one’s personality, memories and emotions, into a computer may one day be possible, but it won’t transfer our biological consciousness and won’t make us immortal.
Uploading one’s mind into a computer, a concept popularized by the 2014 movie Transcendence starring Johnny Depp, is likely to become at least partially possible, but won’t lead to immortality. Major objections have been raised regarding the feasibility of mind uploading. Even if we could surpass every technical obstacle and successfully copy the totality of one’s mind, emotions, memories, personality and intellect into a machine, that would be just that: a copy, which itself can be copied again and again on various computers.
Neuroscientists have not yet been able to explain what consciousness is, or how it works at a neurological level. Once they do, it is might be possible to reproduce consciousness in artificial intelligence. If that proves feasible, then it should in theory be possible to replicate our consciousness on computers too. Or is that jumpig to conclusions ?

Computers will soon be able to simulate the functioning of a human brain. In a near future, artificial superintelligence could become vastly more intellectually capable and versatile than humans. But could machines ever truly experience the whole range of human feelings and emotions, or are there technical limitations ?
In a few decades, intelligent and sentient humanoid robots will wander the streets alongside humans, work with humans, socialize with humans, and perhaps one day will be considered individuals in their own right. Research in artificial intelligence (AI) suggests that intelligent machines will eventually be able to see, hear, smell, sense, move, think, create and speak at least as well as humans. They will feel emotions of their own and probably one day also become self-aware.
There may not be any reason per se to want sentient robots to experience exactly all the emotions and feelings of a human being, but it may be interesting to explore the fundamental differences in the way humans and robots can sense, perceive and behave. Tiny genetic variations between people can result in major discrepancies in the way each of us thinks, feels and experience the world. If we appear so diverse despite the fact that all humans are in average 99.5% identical genetically, even across racial groups, how could we possibly expect sentient robots to feel the exact same way as biological humans ? There could be striking similarities between us and robots, but also drastic divergences on some levels. This is what we will investigate below.

The technological singularity requires the creation of an artificial superintelligence (ASI). But does that ASI need to be modelled on the human brain, or is it even necessary to be able to fully replicate the human brain and consciousness digitally in order to design an ASI ?
Animal brains and computers don’t work the same way. Brains are massively parallel three-dimensional networks, while computers still process information in a very linear fashion, although millions of times faster than brains. Microprocessors can perform amazing calculations, far exceeding the speed and efficiency of the human brain using completely different patterns to process information. The drawback is that traditional chips are not good at processing massively parallel data, solving complex problems, or recognizing patterns.
Newly developed neuromorphic chips are modelling the massively parallel way the brain processes information using, among others, neural networks. Neuromorphic computers should ideally use optical technology, which can potentially process trillions of simultaneous calculations, making it possible to simulate a whole human brain.

Singularity has flopped – that is to say, this week Johnny Depp’s new film Transcendence did not bring in as much as Pirates of the Caribbean. Though there may not have been big box office heat, there is heat behind the film’s subject: Big Data! Sure we miss seeing our affable pirate chasing treasure, but hats off to Mr. Depp who removed his Keith Richards make-up to risk chasing what might be the mightiest challenge of our century.
Singularity, coined by mathematician John von Neumann, is a heady mathematical concept tested by biotech predictions. Made popular by math and music wunderkindt turned gray hair guru of an AI movement Ray Kurzweil, Singularity is said to signify the increasing rate at which artificial intelligence will supersede human intelligence like a jealous sibling. Followers of the Singularity movement (yes, with guru comes followers) envision the time of override in the not to distant future with projections set early as 2017 and 2030. At these times, the dynamics of technology are said to set about a change in our biology, our civilization and “perhaps” nature itself. Within our current reach, we see signs of empowered tech acting out in the current human brain mapping quest and brain-computer interface systems. More to the point, there is an ever increasing onslaught of Google Alerts annoucing biotech enhancements with wearable tech. Yes indeed, here comes the age of smart prosthetics and our own AI upload of medical and personal data to the internet. Suddenly all those Selfies seem more than mere narcissistic postings against the imposing backdrop of Big Data.

The Human Race to the Future (2014 Edition) is the scientific Lifeboat Foundation think tank’s publication first made available in 2013, covering a number of dilemmas fundamental to the human future and of great interest to all readers. Daniel Berleant’s approach to popularizing science is more entertaining than a lot of other science writers, and this book contains many surprises and useful knowledge.
Some of the science covered in The Human Race to the Future, such as future ice ages and predictions of where natural evolution will take us next, is not immediately relevant in our lives and politics, but it is still presented to make fascinating reading. The rest of the science in the book is very linked to society’s immediate future, and deserves great consideration by commentators, activists and policymakers because it is only going to get more important as the world moves forward.
The book makes many warnings and calls for caution, but also makes an optimistic forecast about how society might look in the future. For example, It is “economically possible” to have a society where all the basics are free and all work is essentially optional (a way for people to turn their hobbies into a way of earning more possessions) (p. 6–7).
