A New Reality Materializing: Humans Can Be the New Supercomputer

Illustration: Colourbox Today, people of all backgrounds can contribute to solving serious scientific problems by playing computer games. A Danish research group has extended the limits of quantum physics calculations and simultaneously blurred the boundaries between man and mac. The Danish research team, CODER, has found out, that the human brain can beat the calculating powers of a computer, when it comes to solving quantum-problems. The saying of philosopher René Descartes of what makes humans unique is beginning to sound hollow. 'I think -- therefore soon I am obsolete' seems more appropriate. When a computer routinely beats us at chess and we can barely navigate without the help of a GPS, have we outlived our place in the world? Not quite. Welcome to the front line of research in cognitive skills, quantum computers and gaming. Today there is an on-going battle between man and machine. While genuine machine consciousness is still years into the future, we are beginning to see computers make choices that previously demanded a human's input. Recently, the world held its breath as Google's algorithm AlphaGo beat a professional player in the game Go--an achievement demonstrating the explosive speed of development in machine capabilities. A screenshot of one of the many games that are available. In this case the task is to...

Researchers Teach Machines To Learn Like Humans

A team of scientists has developed an algorithm that captures our learning abilities, enabling computers to recognize and draw simple visual concepts that are mostly indistinguishable from those created by humans. The work, which appears in the latest issue of the journal Science, marks a significant advance in the field -- one that dramatically shortens the time it takes computers to 'learn' new concepts and broadens their application to more creative tasks. A team of scientists has developed an algorithm that captures our learning abilities, enabling computers to recognize and draw simple visual concepts that are mostly indistinguishable from those created by humans. "Our results show that by reverse engineering how people think about a problem, we can develop better algorithms," explains Brenden Lake, a Moore-Sloan Data Science Fellow at New York University and the paper's lead author. "Moreover, this work points to promising methods to narrow the gap for other machine learning tasks." The paper's other authors were Ruslan Salakhutdinov, an assistant professor of Computer Science at the University of Toronto, and Joshua Tenenbaum, a professor at MIT in the Department of Brain and Cognitive Sciences and the Center for Brains, Minds and Machines. When humans are exposed to a new concept -- such as new piece of kitchen equipment,...

China scientist ‘ready’ to clone humans

Boyalife Group shows three cloned puppies in an incubator at a facility in Tianjin, China. (Photo: AFP) The Chinese scientist behind the world’s biggest cloning factory has technology advanced enough to replicate humans, he said, and is only holding off for fear of the public reaction. Boyalife Group and its partners are building the giant plant in the northern Chinese port of Tianjin, where it is due to go into production within the next seven months and aims for an output of one million cloned cows a year by 2020. But cattle are only the beginning of chief executive Xu Xiaochun’s ambitions. In the factory pipeline are also thoroughbred racehorses, as well as pet and police dogs, specialised in searching and sniffing. Boyalife is already working with its South Korean partner Sooam and the Chinese Academy of Sciences to improve primate cloning capacity to create better test animals for disease research. And it is a short biological step from monkeys to humans, potentially raising a host of moral and ethical controversies. “The technology is already there,” Xu said. “If this is allowed, I don’t think there are other companies better than Boyalife that make better technology.” The firm does not currently engage in human cloning activities, Xu said, adding that it has to be “self-restrained” because of possible adverse reaction....

4 Million Year Old Menu: What Our Ancestors Ate

The diet of Australopithecus anamensis, a hominid that lived in the east of the African continent more than 4 million years ago, was very specialized and, according to a scientific study whose principal author is Ferran Estebaranz, from the Department of Animal Biology at the University of Barcelona, it included foods typical of open environments (seeds, sedges, grasses, etc.), as well as fruits and tubers.  Artist's concept for Australopithecus anamensi, Credit: Universidad de Barcelona Australopithecus anamensis (or Praeanthropus anamensis) is a stem-human species that lived approximately four million years ago. Nearly one hundred fossil specimens are known from Kenya and Ethiopia, representing over 20 individuals. Australopithecus anamensis bone fragment, Credit: University of Zurich The work, published in the Journal of Anthropological Sciences, is directed by lecturer Alejandro Pérez Pérez, from the Anthropology Unit of the Department of Animal Biology at the UB, and its co-authors are professor Daniel Turbón and experts Jordi Galbany and Laura M. Martínez. Australipithecus anamensis is a fossil hominid species described in 1995 by a team led by the researcher Meave Leakey and it is considered to be the direct ancestor of Australopithecus afarensis, known as Lucy, which lived in the same region...

Human embryos genetically modified by Chinese scientists

In a world first, researchers at Sun Yat-sen University in Guangzhou, China, admit to having edited the genome of live human embryos to see the effect on a fatal blood disorder, thalassaemia. The research is banned in Europe – but Chinese scientists have confirmed that they recently edited the DNA of human embryos for the very first time. Researchers at Sun Yat-sen University, led by Junjiu Huang, have tried to ease concerns by explaining that they used non-viable embryos, which cannot result in a successful live birth, that were obtained from local fertility clinics. Huang's team used a revolutionary new technique known as CRISPR/Cas9, discovered by scientists at MIT. A total of 86 embryos were injected with the Cas9 protein and left for two days while the gene-editing process took place. Of these, 71 survived and subsequent tests revealed that 28 were successfully spliced, but only a fraction contained the genetic material needed to prevent the fatal blood disorder thalassaemia. Unexpected mutations were also noticed in the genes. "I think that this is a significant departure from currently accepted research practice," said Shirley Hodgson, Professor of Cancer Genetics, St George's University of London. "Can we be certain that the embryos that the researchers were working on were indeed non-viable? Any proposal to do germline...
