DARPA Awards Ginkgo Bioworks and Transcriptic $9.5M to Bring AI into the Lab

The industry partners will use the money to train artificially intelligent laboratory robots.

Many people assume that when robots enter the economy, they’ll snatch low-skilled jobs. But don’t let a PhD fool you — AI-powered robots will soon impact a laboratory near you.

The days of pipetting liquids around were already numbered. Companies like Transcriptic, based in Menlo Park, California, now offer automated molecular biology lab work, from routine PCR to more complicated preclinical assays. Customers can buy time on their ‘robotic cloud lab’ using any laptop and access the results in a web app.

US approves artificial-intelligence device for diabetic eye problems

US regulators Wednesday approved the first device that uses artificial intelligence to detect eye damage from diabetes, allowing regular doctors to diagnose the condition without interpreting any data or images.

The device, called IDx-DR, can diagnose a condition called diabetic retinopathy, the most common cause of vision loss among the more than 30 million Americans living with diabetes.

Its software uses an artificial intelligence algorithm to analyze images of the eye, taken with a retinal camera called the Topcon NW400, the FDA said.

FDA approves AI-powered diagnostic that doesn’t need a doctor’s help

Marking a new era of “diagnosis by software,” the US Food and Drug Administration on Wednesday gave permission to a company called IDx to market an AI-powered diagnostic device for ophthalmology.

What it does: The software is designed to detect greater than a mild level of diabetic retinopathy, which causes vision loss and affects 30 million people in the US. It occurs when high blood sugar damages blood vessels in the retina.

How it works: The program uses an AI algorithm to analyze images of the adult eye taken with a special retinal camera. A doctor uploads the images to a cloud server, and the software then delivers a positive or negative result.

Using Sound To Levitate And Move Things In Three Dimensions

ultrasonic 3D levitation
Japanese researchers have developed a way of not only levitating, but also moving objects three dimensionally using sound waves. The device uses four arrays of speakers to make soundwaves that intersect at a focal point that can be moved up, down, left, and right using external controls. And to human ears the device is completely quiet, as it uses ultrasound.

Occupational exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body, and it has been calculated that exposures above 180 dB may lead to death.[45] The UK’s independent Advisory Group on Non-ionising Radiation (AGNIR) produced a report in 2010, which was published by the UK Health Protection Agency (HPA). This report recommended an exposure limit for the general public to airborne ultrasound sound pressure levels (SPL) of 70 dB (at 20 kHz), and 100 dB (at 25 kHz and above).

The Life Extension is “Just a Fear of Death” Argument

This is a fairly common response to the discussion of extending healthy human lifespans. The idea that fear of dying is the only thing that motivates the advocates, supporters, and scientists working on rejuvenation biotechnology and ending age-related diseases.

These days, war is not really portrayed in a very good light. When we think about war, we think about genocide, mass murder, and slaughter, and we call for an end to it. The popular sentiment is that war is bad and we should just do away with it. However, once upon a time, things were rather different, and soldiers fighting wars were not seen as victims of mindless violence. Losing your life in battle was considered glorious and noble, and your family would be proud of you for fighting in the name of your country, your God, or whatever. People who were afraid of dying and refused to fight were regarded as cowards, most certainly not as pacifists of a strong moral fiber, and were possibly executed; being a conscientious objector was not yet a thing, and human rights weren’t either.

This is sheer madness to us, but back in the day, it was entirely normal. Most of us will probably think people must have been crazy to let themselves be fooled into believing such nonsense, but that’s the power of propaganda for you.

The modern age of pro-death propaganda

However, the story is not completely over even today. This may be because of past glorification of death, stale ideas about the “circle of life”, a widespread coping mechanism, or a combination of the three, but at least in certain circumstances, being afraid of death is still seen as a sign of cowardice and sometimes also inferiority.

Brain implants put paralyzed man back in touch with himself

Researchers at Caltech have induced a range of sensations in the arm of a paralyzed man. The breakthrough comes courtesy of electrodes implanted in the brain, which stimulated the neurons to produce different feelings depending on the type of electrical signals. The team says the research could eventually lead to advanced prosthetic limbs that allow users to feel realistic sensations through them.

Plenty of exciting research is being conducted to help paralyzed people regain control of and feeling in their limbs. The NeuroLife system has helped a quadriplegic man move his arms again using just his thoughts, allowing him to perform a number of actions. Electrical nerve stimulation, both with and without electrode implants, has helped several people voluntarily move their legs again, often for the first time in years.

In this new study, Caltech researchers implanted two tiny arrays of electrodes into the somatosensory cortex, the small region of the brain responsible for the body’s sensations of movement or position, as well as cutaneous sensations such as touch, pressure and vibration.

Some People Are Their Own Identical Twins, And The Science Behind That Is Fascinating

Take any two cells from your body and there’s a good chance their genetic sequences will be a match. That is, unless you happen to have what’s referred to in the medical literature as a ‘tetragametic chimerism’ – a condition that causes separate fertilised embryos to merge into a single body.

Once thought to be rare among humans, there’s good reason to suspect we might be seeing a lot more of it in the future.

The truth is, nobody is really certain how many humans have cells in their body that once belonged to a sibling.

Your Body Is a Teeming Battleground

It’s time to rethink the quest to control aging, death, and disease—and the fear of mortality that fuels it.

I went to medical school, at least in part, to get to know death and perhaps to make my peace with it. So did many of my doctor friends, as I would find out. One day—usually when you’re young, though sometimes later—the thought hits you: You really are going to die. That moment is shocking, frightening, terrible. You try to pretend it hasn’t happened (it’s only a thought, after all), and you go about your business, worrying about this or that, until the day you put your hand to your neck—in the shower, say—and … What is that? Those hard lumps that you know, at first touch, should not be there? But there they are, and they mean death. Your death, and you can’t pretend anymore.

I never wanted to be surprised that way, and I thought that if I became a doctor and saw a lot of death, I might get used to it; it wouldn’t surprise me, and I could learn to live with it. My strategy worked pretty well. Over the decades, from all my patients, I learned that I would be well until I got sick and that although I could do some things to delay the inevitable a bit, whatever control I had was limited. I learned that I had to live as if I would die tomorrow and at the same time as if I would live forever. Meanwhile, I watched as what had been called “medical care”—that is, treating the sick—turned into “health care,” keeping people healthy, at an ever-rising cost.

Contact Lens Kinda Makes You Cyborgy

This one’s kinda hard to swallow so take a deep breath, open your minds, and pretend it’s 2100. I CONTACT is essentially a mouse fitted to your eyeball. The lens is inserted like any other normal contact lens except it’s laced with sensors to track eye movement, relaying that position to a receiver connected to your computer. Theoretically that should give you full control over a mouse cursor. I’d imagine holding a blink correlates to mouse clicks.

The idea was originally created for people with disabilities but anyone could use it. Those of us too lazy to use a mouse now have a free hand to do whatever it is people do when they sit at the computer for endless hours. I love the idea but there is a caveat. How is the lens powered? Perhaps in the future, electrical power can be harnessed from the human body, just not in a Matrix creepy-like way.
