Summary: Activating p38gamma, a naturally protective enzyme in the brain, may help to prevent the development of Alzheimer’s disease symptoms. Researchers showed the naturally protective effects of p38gamma could be harnessed to improve memory in the later stages of Alzheimer’s disease.

A ground-breaking new treatment developed by Macquarie University scientists has reversed the effects of memory loss associated with Alzheimer’s disease in a study of mice with advanced dementia.

Single particles of light can be used for remote 3D surveillance https://lifeboat.com/blog/2020/07/single-particles-of-light-can-be-used-for-remote-3d-surveillance Sat, 01 Aug 2020 03:03:20 +0000 https://lifeboat.com/blog/2020/07/single-particles-of-light-can-be-used-for-remote-3d-surveillance

Researchers have taken 3D images by bouncing individual photons from a laser off a building 45 kilometres away, more than 4 times farther than ever before.

Non-magnetic material made magnetic using electricity for the first time https://lifeboat.com/blog/2020/07/non-magnetic-material-made-magnetic-using-electricity-for-the-first-time Sat, 01 Aug 2020 00:22:21 +0000 https://lifeboat.com/blog/2020/07/non-magnetic-material-made-magnetic-using-electricity-for-the-first-time

Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. The find could be a step towards making electronic components out of common materials that might not otherwise be suitable.

Put simply, ferromagnetism – the strongest form of the phenomenon – arises in a material when the majority of electrons in its atoms spin in the same direction. For non-magnetic materials, the electrons are usually paired up so that their opposite spins cancel out the magnetic field.

There aren’t many substances that are natively ferromagnetic, but the most common ones are iron, cobalt and nickel, as well as their alloys. That doesn’t give engineers all that much to work with when creating electronic devices.

A new neural network could help computers code themselves https://lifeboat.com/blog/2020/07/a-new-neural-network-could-help-computers-code-themselves Fri, 31 Jul 2020 22:24:41 +0000 https://lifeboat.com/blog/2020/07/a-new-neural-network-could-help-computers-code-themselves

Computer programming has never been easy. The first coders wrote programs out by hand, scrawling symbols onto graph paper before converting them into large stacks of punched cards that could be processed by the computer. One mark out of place and the whole thing might have to be redone.

Nowadays coders use an array of powerful tools that automate much of the job, from catching errors as you type to testing the code before it’s deployed. But in other ways, little has changed. One silly mistake can still crash a whole piece of software. And as systems get more and more complex, tracking down these bugs gets more and more difficult. “It can sometimes take teams of coders days to fix a single bug,” says Justin Gottschlich, director of the machine programming research group at Intel.

Fooling deep neural networks for object detection with adversarial 3D logos https://lifeboat.com/blog/2020/07/fooling-deep-neural-networks-for-object-detection-with-adversarial-3d-logos Fri, 31 Jul 2020 22:24:34 +0000 https://lifeboat.com/blog/2020/07/fooling-deep-neural-networks-for-object-detection-with-adversarial-3d-logos

Over the past decade, researchers have developed a growing number of deep neural networks that can be trained to complete a variety of tasks, including recognizing people or objects in images. While many of these computational techniques have achieved remarkable results, they can sometimes be fooled into misclassifying data.

An adversarial attack is a type of cyberattack that specifically targets deep neural networks, tricking them into misclassifying data. It does this by creating adversarial data that closely resembles and yet differs from the data typically analyzed by a deep neural network, prompting the network to make incorrect predictions, failing to recognize the slight differences between real and adversarial data.

In recent years, this type of attack has become increasingly common, highlighting the vulnerabilities and flaws of many deep neural networks. A specific type of that has emerged in recent years entails the addition of adversarial patches (e.g., logos) to images. This attack has so far primarily targeted models that are trained to detect objects or people in 2-D images.

The future of AI: 12 possible breakthroughs, and beyond https://lifeboat.com/blog/2020/07/the-future-of-ai-12-possible-breakthroughs-and-beyond Fri, 31 Jul 2020 22:24:16 +0000 https://lifeboat.com/blog/2020/07/the-future-of-ai-12-possible-breakthroughs-and-beyond

Interesting.


The AI of 5–10 years time could be very different from today’s AI. The most successful AI systems of that time will not simply be extensions of today’s deep neural networks. Instead, they are likely to include significant conceptual breakthroughs or other game-changing innovations.

That was the argument I made in a presentation on Thursday to the Global Data Sciences and Artificial Intelligence meetup. The chair of that meetup, Pramod Kunji, kindly recorded the presentation.
