Last year, scientists took a big step towards creating the next generation of computers.
For the first time ever, they stored light-based information as sound waves on a computer chip — something the researchers compared to capturing lightning as thunder.

Researchers in Oregon State University’s College of Engineering have taken a key step toward the rapid manufacture of flexible computer screens and other stretchable electronic devices, including soft robots.
The advance by a team within the college’s Collaborative Robotics and Intelligent Systems Institute paves the way toward the 3D printing of tall, complicated structures with a highly conductive gallium alloy.
Researchers put nickel nanoparticles into the liquid metal, galinstan, to thicken it into a paste with a consistency suitable for additive manufacturing.
An international group of researchers has made a decisive step towards creating the technology to achieve simulations of brain-scale networks on future supercomputers of the exascale class. The breakthrough, published in Frontiers in Neuroinformatics, allows larger parts of the human brain to be represented, using the same amount of computer memory. Simultaneously, the new algorithm significantly speeds up brain simulations on existing supercomputers.
The human brain is an organ of incredible complexity, composed of 100 billion interconnected nerve cells. However, even with the help of the most powerful supercomputers available, it is currently impossible to simulate the exchange of neuronal signals in networks of this size.
“Since 2014, our software can simulate about one percent of the neurons in the human brain with all their connections,” says Markus Diesmann, Director at the Jülich Institute of Neuroscience and Medicine (INM-6). In order to achieve this impressive feat, the software requires the entire main memory of petascale supercomputers, such as the K computer in Kobe and JUQUEEN in Jülich.

In the course of the last century, science fiction has been a harbinger of things to come. From the automatic sliding doors of Star Trek to visual communication, cyberspace, and even the moon landing, many of our present technological achievements were dreamed up in the futuristic visions of science fiction authors of the 1960s and 70s. Indeed, the fantastical world of science fiction, while not intended to be prophetic, has ended up acting as a blueprint for our modern world.
We have learned from science fiction not only the possibilities of technology, however, but also its irreconcilable dangers. Readers of the genre will recognize the many stories warning us of the hazards of space travel, mind enhancement, and artificial intelligence. These fictional accounts cautioned that if we were not careful, our freedom to transform the world around us would transmogrify into a self-enforced slavery.
Nonetheless, while many of us remembered that these were just stories, intended as speculations about a possible future—in other words, they were fiction before science—through them, we became used to the idea that any advanced technology was inherently dangerous and its use always suspect. Moreover, it became a commonplace idea that technologies whose aim was to change or transform the human being—whether genetic, biological or reconstructive—would lead to a future worthy of Mary Shelley’s Frankenstein.
Every major tech company is looking at quantum computers as the next big breakthrough in computing. Teams at Google, Microsoft, Intel, IBM and various startups and academic labs are racing to become the first to achieve quantum supremacy — that is, the point where a quantum computer can run certain algorithms faster than a classical computer ever could. Today, Google said that it believes that Bristlecone, its latest quantum processor, will put it on a path to reach quantum supremacy in the future.
The purpose of Bristlecone, Google says, it to provide its researchers with a testbed “for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimization, and machine learning.”
Food scientists and startups are trying to make meat more ethically appealing by growing it — cell by cell — in a lab instead of on a farm. Even some vegans support so-called “clean” meat. But can lab grown meat overcome the dreaded “yuck factor?”

Before the 7.6 billion people alive today, demographers estimate that about 100 billion people lived and died. This is the reality of the human condition. Memento mori, as medieval Christians reflected—Remember that you have to die.
What if it didn’t have to be this way? There are, in fact, organisms whose bodies steadily and reliably replace cells with healthier cells, and whose tissues and organs self-repair and maintain their vigor. They’re called children. And there are cells in adults that divide indefinitely. They’re called cancer. What if there were a way to genetically re-engineer and chemically reprogram our cells to divide indefinitely like they do in children, and to continue this process throughout adulthood without becoming cancerous? Could we become immortal?
“I don’t want to achieve immortality through my work,” Woody Allen once said, “I want to achieve immortality through not dying. I don’t want to live on in the hearts of my countrymen; I want to live on in my apartment.” There are today well-funded groups of scientists who believe we can do just that. If these techno-dreamers succeed, would you want to live for 150 years? 300 years? Or even 500 years? I’m not talking about being brain-dead and bedridden on a morphine drip. I mean living a full, rich physical and mental life for centuries, possibly forever. Would you opt for immortality?
China is intensifying its push into space, and broadening its astronaut recruiting.
The Chinese government, which plans to increase the number of manned missions in its military-backed space program to around two a year, will soon begin recruiting civilian astronauts, Yang Liwei, deputy director of the China Manned Space Engineering Office, told reporters on the sidelines of a ceremonial parliament session this weekend. That’s a departure from China’s practice of drawing its astronauts from among air force pilots.
Yang—who was China’s first man in space in 2003—said the trainees could include private-sector maintenance engineers, payload specialists, pilots, scientists, and people from universities and other research institutions, according to the Associated Press. More women are also being encouraged to apply. The loosening of restrictions comes amid NASA’s announcement that it has recruited America’s most competitive class of astronauts ever, as well as other initiatives like Canada’s Hunger Games -style search for new astronauts on the internet.

Saturn, Mars and Jupiter are all in a row this week in the pre-dawn south-eastern sky.
