Thanks to genetically engineered pigs, the donor-organ shortage could soon be a think of the past.

ANCHORING A ROW of family photos in Joseph Tector’s office is a framed, autographed picture of Baby Fae, the California newborn who made headlines in 1984 when she received a baboon’s heart to replace her own malfunctioning organ.

It’s inscribed “To Joe” by Leonard L. Bailey, the surgeon who turned to the monkey heart as the only option to keep his patient alive. Bailey snapped the picture about five days after the operation, while Stephanie Fae Beauclair was sleeping. A strip of surgical tape runs down the center of her chest from neck to diaper, marking the incision line where her rib cage was pulled apart to make the swap. Baby Fae would die less than three weeks later.

It’s an unsettling image to come upon while glancing over snapshots of someone’s dutifully smiling children. But to Tector, who was 19 at the time of Baby Fae’s surgery, the cross-species organ transplant was the most inspiring thing he’d ever heard of. “I remember where I was when the news broke,” he says. “At that moment I knew exactly what I wanted to do with my life.” What he wanted to do with his life, though he may not have articulated it precisely this way, was to become a surgeon-scientist trying to crack the problem of xenotransplantation — the placing of animal organs into human bodies.

Is Colonizing Mars the most important project in human history?

The Robotic Arm on NASA's Phoenix Mars Lander carries a scoop of Martian soil bound for the spacecraft's microscope

The Red Planet is a freezing, faraway, uninhabitable desert. But protecting the human species from the end of life on Earth could save trillions of lives.

The Earth and Mars are a bit like fraternal twins that slowly grew apart. Four billion years ago, both planets were warm, sheathed by protective atmospheres, and carved with rivers and pools of liquid water. But today, Mars is an irradiated desert enveloped by a thick miasma of carbon dioxide, while its twin is a sensationally fertile orb and, for all we know, the universe’s cosmic jackpot of life.

These divergent stories make scientists immensely curious: Can we discover evidence of a fecund past in the Martian ground? We’re closer than ever to finding out. Ellen Stofan, the former chief scientist of nasa and current head of the National Air and Space Museum, has predicted that we will find evidence of past life on Mars in as little as a decade.

Quantum ‘compass’ promises navigation without using GPS

0A352874-84C8-4C6A-BBF6-D845749A6663

It could keep society humming when satellites fail.

GPS is vital to modern navigation, but it’s extremely fragile. Never mind coverage — if a satellite fails or there’s a jamming attack, it quickly becomes useless. Scientists may have a much more robust answer, though. Scientists have demonstrated a “commercially viable” quantum accelerometer that could provide navigation without GPS or other satellite technology. The device uses lasers to cool atoms to extremely low temperatures, and then measures the quantum wave properties of those atoms as they respond to acceleration.

The future of cities

pic_the_future_of_cities_main

Cities may occupy just 2 per cent of the earth’s land surface, but they are home to more than half of the world’s population and generate 80 per cent of all economic output. And their dominance is growing: by 2045, an extra 2 billion people will live in urban areas.

At Pictet, we think it will put pressure on infrastructure, resources and the environment.

Encouragingly, those responsible for planning and building the urban centres of the future are up to the challenge. Worldwide, authorities are working ever more closely with the private sector in an effort to make our cities safer, more sustainable and better connected.

That’s good news for the planet.

‘Human brain’ supercomputer with 1 million processors switched on for first time

C8573089-4187-4669-94AE-297BCA469014

The world’s largest neuromorphic supercomputer designed and built to work in the same way a human brain does has been fitted with its landmark one-millionth processor core and is being switched on for the first time.

The newly formed million-processor-core Spiking Neural Network Architecture (SpiNNaker) machine is capable of completing more than 200 million million actions per second, with each of its chips having 100 million moving parts.

To reach this point, it has taken £15million in funding, 20 years in conception and over 10 years in construction, with the initial build starting way back in 2006. The project was initially funded by the EPSRC and is now supported by the European Human Brain Project. It is being switched on for the first time on Friday, 2 November.

Scientists create a rare fifth form of matter in space for the first time ever

F66CF898-C590-4D04-A5A9-088BD035EB32

For a few minutes on Jan. 23, 2017, the coldest spot in the known universe was a tiny microchip hovering 150 miles over Kiruna, Sweden.

The chip was small — about the size of a postage stamp — and loaded with thousands of tightly-packed rubidium-87 atoms. Scientists launched that chip into space aboard an unpiloted, 40-foot-long (12 meters) rocket, then bombarded it with lasers until the atoms inside it cooled to minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius) — a fraction of a fraction of a degree above absolute zero, the coldest possible temperature in nature.

Why are robotics companies dying?

842B09EE-C107-4AB3-8DDC-90237096D160

Rethink Robotics shuttered its doors and closed for good on October 4, 2018. For many casual observers the collapse of a much-celebrated company, founded by preeminent artificial intelligence (AI) researcher and minor celebrity Rodney Brooks was a surprise. To others it’s just the latest indication of the trouble in robotics land. According to the company, Rethink Robotics was forced to shut its doors when it couldn’t find additional funding, and in a final attempt to sell the company and/or its assets it couldn’t find a buyer.

Rethink Robotics wasn’t the only robotics company forced to close its doors in the past year. Mayfield Robotics, developers of the social robot Kuri, closed down a few months before Rethink in August 2018, despite just making its debut one year earlier at CES 2017. Prior to that, Jibo, makers of a personal robotics device also shut down even after having raised over $70 Million. These companies shut down despite collectively raising several hundred million dollars in funding and developing their products over many years.

Reaction Pre-cooled Engines could deliver reusable hypersonic planes by 2025

BF5C3008-C6BB-4F83-B9EB-A10CAD74E68B

Reaction Engines of the UK could be part of a winning group of bidders for open-ended hypersonic weapons development.

They have proven an innovative pre-cooling system which does not require the development of new materials to handle the heat of hypersonic flight speeds.

The US Air Force Research Labs are already working with them. They would need to partner with US companies like Lockheed or Boeing to get the big military contract.

The pre-coolers are made from thousands of thin-walled tubes to provide high surface area to low weight. Each tube is joined to an inlet and outlet manifold, which allows coolant to be injected and removed for the cooling process. We’re the only people in the world with the heat exchanger manufacturing experience to bond thousands of joints in a single operation, and achieve zero leakage. The joints in our pre-cooler modules are hermetically sealed, meaning that the gas which escapes can be measured by the molecule.

Scientists have created programmable shape-shifting liquid metal

C7FE4AEA-96F6-4AA0-BC3E-8DB6F7E550CC

Researchers at the University of Sussex and Swansea University have applied electrical charges to manipulate liquid metal into 2D shapes such as letters and a heart. The team says the findings represent an “extremely promising” new class of materials that can be programmed to seamlessly change shape. This open up new possibilities in ‘soft robotics’ and shape-changing displays, the researcher say.

While the invention might bring to mind the film Terminator 2, in which the villain morphs out of a pool of liquid metal, the creation of 3D shapes is still some way off. More immediate applications could include reprogrammable circuit boards and conductive ink.

Robot masters human balancing act

Mercury, a biped robot developed in Cockrell School of Engineering professor Luis Sentis’ Human Centered Robotics Lab, is able to maintain balance when hit unexpectedly or when force is applied without warning.

AUSTIN, Texas — When walking in a crowded place, humans typically aren’t thinking about how we avoid bumping into one another. We are built to use a gamut of complex skill sets required to execute these types of seemingly simple motions.

Now, thanks to researchers in the Cockrell School of Engineering at The University of Texas at Austin, robots may soon be able to experience similar functionality. Luis Sentis, associate professor in the Department of Aerospace Engineering and Engineering Mechanics, and his team in the Human Centered Robotics Laboratory have successfully demonstrated a novel approach to human-like balance in a biped robot.

The next tech talent shortage: Quantum computing researchers

00C20DE7-DC9D-4649-988B-62619F81A311

Christopher Savoie, founder and chief executive of a start-up called Zapata, offered jobs this year to three scientists who specialize in an increasingly important technology called quantum computing. They accepted.

Several months later, the Cambridge, Mass., company was still waiting for the State Department to approve visas for the specialists. All three are foreigners, born in Europe and Asia.

Whether the delays were the result of tougher immigration policy or just red tape, Mr. Savoie’s predicament was typical of a growing concern among American businesses and universities: Unless policies and priorities change, they will have trouble attracting the talent needed to build quantum technology, which could make today’s computers look like toys.

Scientists create artificial wood that is water – and fire resistant

B9857A1E-8C8D-4630-8BFF-1D2C31E4E415

The synthetic material is faster to make than natural wood.

A new lightweight substance is as strong as wood yet lacks its standard vulnerabilities to fire and water.

To create the synthetic wood, scientists took a solution of polymer resin and added a pinch of chitosan, a sugar polymer derived from the shells of shrimp and crabs. They freeze-dried the solution, yielding a structure filled with tiny pores and channels supported by the chitosan. Then they heated the resin to temperatures as high as 200 degrees Celsius to cure it, forging strong chemical bonds.
