ADELPHI, Md. — A U.S. Army Research Laboratory biotechnology scientist recently published an editorial article on the future directions of synthetic biology research to meet critical Army needs in the Synthetic Biology edition of the Journal of the American Chemical Society.

In the publication, Dr. Bryn Adams, who works in ARL’s Bio-Technology Branch, highlights examples of robust, tractable bacterial species that can meet the demands of tomorrow’s state-of-the-art in synthetic biology.

“ACS Synthetic Biology is the premier synthetic biology journal in the world, with a wide readership of biologists, chemists, physicists, engineers and computer programmers,” Adams said. “A publication in this journal allows me to challenge the leaders in the field to meet a Department of Defense specific need — the need for new synthetic biology chassis organisms, or host cell, and toolkits to build complex circuits in them.”

Whenever cybersecurity is discussed, the topic of biometric authentication rises alongside it as a better, more effective, more secure method of security. But is it? Do biometrics actually provide a safer way to complete purchase transactions online?

“Biometrics are a device-specific authentication method,” said Madeline Aufseeser, CEO of online fraud prevention company Tender Armor, of the ways biometric authentication is presently used to secure a digital purchase transaction (as opposed to logging into a bank’s web site, to view an account or transfer money). “Typically the same biometric method does not work across multiple purchasing channels today. The fingerprint used to make a purchase with a smartphone cannot necessarily be used to authenticate a phone order purchase or purchase made with a computer. When you confirm [a purchase transaction] with your fingerprint on a smartphone, all that’s saying is that’s the same fingerprint that’s allowed to use this phone, or the specific application on the phone. Because the fingerprint is only resident and stored on the phone, the phone is authenticating itself, not the cardholder conducting the transaction.”

This sounds a little odd compared to what we might have heard about the capabilities of biometrics previously, mainly because it goes against a core assumption: that a biometric identifier (like a fingerprint) goes with transactional data, from the phone or device, to the payment processor, to the merchant.

Chatbots have enjoyed wide adoption already, but with new developments in artificial intelligence and other technology, they will become even more useful to businesses.

Rarely a week goes by at Wareable where a patent from some big tech company doesn’t get us guessing about the future.

Like Hansel and Gretel with smartwatches, we follow the proverbial tech crumbs all the way to the end, but we’re quick to forget how many of the ideas actually make the cut — and which get lost along the way.

So we’re going to a mini-series we’re calling ‘The patented history and future of…’, looking at some of the big launches in wearable tech, starting with the Apple Watch. These are going to be miniature timelines, small trips down memory lane looking at the patents that led up to the announcement and those that have happened since, to see what came true, what didn’t, and what might still be to come.

Tomi Laurila’s research topic has many quirky names.

‘Nanodiamond, nanohorn, nano-onion…’ lists off the Aalto University Professor, recounting the many nano-shapes of carbon. Laurila is using these shapes to build new materials: tiny sensors, only a few hundred nanometres across, that can achieve great things due to their special characteristics.

Tl.pngFor one, the sensors can be used to enhance the treatment of neurological conditions. That is why Laurila, University of Helsinki Professor Tomi Taira and experts from HUS (the Hospital District of Helsinki and Uusimaa) are looking for ways to use the sensors for taking electrochemical measurements of biomolecules. Biomolecules are e.g. neurotransmitters such as glutamate, dopamine and opioids, which are used by nerve cells to communicate with each other.

Weird quantum effects are so delicate it seems they could only happen in a lab. How on Earth can life depend on them?

The point of the most famous thought-experiment in quantum physics is that the quantum world is different from our familiar one. Imagine, suggested the Austrian physicist Erwin Schrödinger, that we seal a cat inside a box. The cat’s fate is linked to the quantum world through a poison that will be released only if a single radioactive atom decays. Quantum mechanics says that the atom must exist in a peculiar state called ‘superposition’ until it is observed, a state in which it has both decayed and not decayed. Furthermore, because the cat’s survival depends on what the atom does, it would appear that the cat must also exist as a superposition of a live and a dead cat until somebody opens the box and observes it. After all, the cat’s life depends on the state of the atom, and the state of the atom has not yet been decided.

Yet nobody really believes that a cat can be simultaneously dead and alive. There is a profound difference between fundamental particles, such as atoms, which do weird quantum stuff (existing in two states at once, occupying two positions at once, tunnelling through impenetrable barriers etc) and familiar classical objects, such as cats, that apparently do none of these things. Why don’t they? Simply put, because the weird quantum stuff is very fragile.

Can a fluid analogue of a black hole point physicists toward the theory of quantum gravity, or is it a red herring?

Scientists have observed how quantum superpositions build up in a helium atom within femtoseconds. Just like in the famous double-slit experiment, there are two ways to reach the final outcome.

Quantum computing is about to get more complex. Researchers have evidence that large molecules made of nickel and chromium can store and process information in the same way bytes do for digital computers. The researchers present algorithms proving it’s possible to use supramolecular chemistry to connect “qubits,” the basic units for quantum information processing, in Chem on November 10. This approach would generate several kinds of stable qubits that could be connected together into structures called “two-qubit gates.”

“We have shown that the chemistry is achievable for bringing together two-qubit gates,” says senior author Richard Winpenny, Head of the University of Manchester School of Chemistry. “The molecules can be made and the two-qubit gates assembled. The next step is to show that these two-qubit gates work.”
