The Future of Humanity’s Food Supply Is in the Hands of AI

Perhaps it’s serendipitous, then, that the machines have finally arrived. Truly smart, truly impressive robots and machine learning algorithms that may help usher in a new Green Revolution to keep humans fed on an increasingly mercurial planet. Think satellites that automatically detect drought patterns, tractors that eyeball plants and kill the sick ones, and an AI-powered smartphone app that can tell a farmer what disease has crippled their crop.

Forget scarecrows. The future of agriculture is in the hands of the machines.

A Digital Green Thumb

Deep learning is a powerful method of computing in which programmers don’t explicitly tell a computer what to do, but instead train it to recognize certain patterns. You could feed a computer photos of diseased and healthy plant leaves, labeled as such. From these it will learn what diseased and healthy leaves look like, and determine the health of new leaves on its own.

AI ‘doctors’ will diagnose your X-rays

An Israeli medical imaging company has signed a deal with a Utah-based healthcare provider that could change the way we diagnose certain conditions. Zebra Medical Imaging is teaming up with Intermountain to work on a neural network that will compare fresh X-rays with the “millions” stored in its own database. The eventual aim of the project is to offer up suggestions to radiographers and other medical professionals and eliminate costly misdiagnoses.

For instance, let’s imagine that you’ve gone to hospital for some unknown condition and you get an X-ray. Rather than handing the slide to a doctor, who could miss a small shadow or other minor clue, the image would be handed to the computer. It would use deep learning to trawl an anonymized patient database looking for any anomalies that you might be suffering from. The current system will work on bone health, cardiovascular analysis and lung conditions, although who knows where the possibilities will end.

As deep learning technology gets more powerful, smaller and significantly cheaper, the potential for AI to assist doctors becomes more realistic. IBM has spent the last few years pushing Watson, its homegrown supercomputer, as a system to aid decision making for patients. At the same time, companies like LG are trying to shrink medical imaging technology to end the days of bulky hospital equipment being available for a chosen few. All in all, the idea of a medical tricorder is going from fantastical to plausible in less time than you’d expect.

Is aging inevitable? Not necessarily for sea urchins

Sea urchins are remarkable organisms. They can quickly regrow damaged spines and feet. Some species also live to extraordinary old ages and—even more remarkably—do so with no signs of poor health, such as a decline in regenerative capacity or an increase in age-related mortality. These ocean Methuselahs even reproduce as if they were still youngsters.

MDI Biological Laboratory Associate Professor James A. Coffman, Ph.D., is studying the of sea urchins in hopes that a deeper understanding of the process of regeneration, which governs the regeneration of aging tissues as well as lost or damaged body parts, will lead to a deeper understanding of the aging process in humans, with whom sea urchins share a close genetic relationship.

In a paper recently published in Aging Cell, a leading journal in the field of aging biology, with Andrea G. Bodnar, Ph.D., of the Bermuda Institute of Ocean Studies, the scientists shed new light on the aging process in sea urchins, raising the prospect that the physical decline that typically accompanies aging is not inevitable.

Acoustic engineering transcribes crackling knee sounds into moving graph

New method for precisely identifying and treating fractures.

You’ve injured your knee. A doctor straps a listening device to it, and the noises you hear coming out of it are cringe-worthy. “Crackle! Krglkrglkrgl! Snap!”

Your isn’t breaking; it’s only bending, and in the future, those sounds could help doctors determine whether the convalescing joint is healthy yet, or if it needs more therapy.

Research engineers at the Georgia Institute of Technology are developing a knee band with microphones and vibration sensors to listen to and measure the sounds inside the joint.

Precision radiation helps ward off first-time mom’s brain tumor

Another exampme of how precision works.

While pregnant with her first child, Rhea Birusingh started experiencing blurry vision that her OB-GYN dismissed as an expected pregnancy-related change, but three months later, she went to her ophthalmologist, who discovered an inoperable 2-centimeter benign brain tumor behind her right eye. Now, nearly four months later, Birusingh’s son is healthy and her vision is normal, thanks to a powerful, precise radiation treatment.

“When you’re a pathologist and your eyes are a money maker, you start to get a little bit worried,” Birusingh, 37, of Howey-in-the-Hills, Florida, told FoxNews.com.

Doctors at UF Health Cancer Center – Orlando Health decided to use the treatment, called proton beam therapy, because Birusingh’s tumor was adjacent to her hippocampus, which is critical for short- and long-term memory and learning. Proton beam therapy works differently from conventional radiation treatments, which rely on X-rays. Birusingh was the first patient to undergo the treatment— which uses a three-story, 200,000 pound machine— at the hospital.

Mechanism that reduces effect of cocaine on brain discovered

Very promising. Wonder how effective it is with Prescription Med. Addictions.

A type of brain cell known as microglia plays a key role in reducing the effects of cocaine in the brain, according to a major study by a team from the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal.

The discovery, published in the journal Neuron, establishes for the first time that microglia can diminish the adverse changes to neural circuitry brought on by the chronic use of and has significant implications for developing an effective treatment for addiction.

Microglia may not be as well known as neurons, the that relay messages, but they have many important functions. They constantly monitor their environment, and can act to maintain normal functioning. When they find something amiss, they can produce molecules that instruct neurons to make adaptive changes to their connections. One such example is the inflammatory molecule known as (TNF).

This college student 3D printed his own plastic braces for $60 — and they actually fixed his teeth

Ever dream of becoming a dentist? Or, have family members needing new dentures? Or, know that one person who would look good if they only had some teeth. This 3D Printer is your answer.

An undergraduate at New Jersey Institute of Technology made his own plastic braces using a 3D printer, $60 of materials, and a healthy dose of ingenuity — and they actually worked.

Amos Dudley had braces in middle school, but he didn’t wear a retainer like he was supposed to, so his teeth slowly shifted back.

He didn’t want to shell out thousands of dollars for a whole new round of braces, so the digital-design major decided to make his own.

Gene helps prevent heart attack, stroke — and may offer way to block effects of aging

CHARLOTTESVILLE, Va., May 17, 2016 — A gene that scientific dogma insists is inactive in adults actually plays a vital role in preventing the underlying cause of most heart attacks and strokes, researchers at the University of Virginia School of Medicine have determined. The discovery opens a new avenue for battling those deadly conditions, and it raises the tantalizing prospect that doctors could use the gene to prevent or delay at least some of the effects of aging.

“Finding a way to augment the expression of this gene in adult cells may have profound implications for promoting health and possibly reversing some of the detrimental effects with aging,” said researcher Gary K. Owens, PhD, director of UVA’s Robert M. Berne Cardiovascular Research Center.
