Stem cell therapy shows early promise against macular degeneration

Posted by in categories: biotech/medical, life extension

Age-related macular degeneration is the leading cause of vision loss in seniors, and existing treatments are few.

But now, experiments in pigs and rats suggest that stem cell therapy might help curb at least one form of the disease.

The results could soon lead to the first human trials of this therapy for macular degeneration, according to researchers from the U.S. National Eye Institute (NEI).

On-chip optical link is created on electronic chip for the first time

Researchers of the University of Twente (UT; Enschede, Netherlands) have, for the first time, succeeded in connecting two parts of an electronic chip using an on-chip optical link, all fabricable with standard CMOS technology — a long-sought-after goal, as intrachip connection via light is almost instantaneous and also provides electrical isolation. Such a connection can, for example, be a safe way of connecting high-power electronics and digital control circuitry on a single chip without a direct electrical link. Vishal Agarwal, a UT PhD student, created a very small optocoupler circuit that delivers a data rate of megabits per second in an energy-efficient way.

Scientists Figured Out How to Separate Pain From Physical Suffering

Posted by in categories: biotech/medical, neuroscience

“We wanted to be more precise here and identify the region and the cells that are responsible for pain unpleasantness,” Scherrer tells Inverse. “We thought if we could find the center, or the cells in the brain that make pain unpleasant, perhaps acting on these cells could be a good strategy to reduce pain in chronic pain patients.”

It’s already established that the amygdala plays a role in the emotional component of pain, but this team actually found the exact cells in the amygdala responsible for those unpleasant pain messages by using a “miniscope,” a tool created by Schnitzer, and observing how mice responded to painful stimuli.

When mice in their experiment were exposed to a drop of scalding water, a given a pinprick, or asked to run along unpleasantly hot tracks, these cells in the amygdala were highly active. Importantly, Schnitzer adds, they didn’t light up when the mice were exposed to other stimuli like sugar water or a bad smell. “Every time mice were unpleased with the stimulation, we saw that these cells were turned on,” he adds.

Opal-filled fossils reveal timid, dog-size dinosaur that lived down under

Posted by in category: futurism

When Mike Poben, an opal buyer and and fossil fanatic, bought a bucket of opal from an Australian mine, he was surprised to find to find what looked like an ancient tooth in the pile.

Later, he also found a fossilized jaw piece — one that was shiny and glistening with opal.

After showing the two opalized specimens to paleontologists in 2014, Poben learned that they were part of a previously unknown dog-size dinosaur species, a new study finds. This dino lived about 100 million years ago in Australia, back when the landscape was lush and dotted with lakes. [Photos: Meet Wade, the Long-Necked Dinosaur from Down Under].

Bizarre Superfluid Could Explain the Existence of the Modern Universe

Posted by in categories: particle physics, quantum physics

Back in the first moment of the universe, everything was hot and dense and in perfect balance. There weren’t any particles as we’d understand them, much less any stars or even the vacuum that permeates space today. The whole of space was filled with homogeneous, formless, compressed stuff.

Then, something slipped. All that monotonous stability became unstable. Matter won out over its weird cousin, antimatter, and came to dominate the whole of space. Clouds of that matter formed and collapsed into stars, which became organized into galaxies. Everything that we know about started to exist.

So, what happened to tip the universe out of its formless state? [How Quantum Entanglement Works (Infographic)].
