Sharrock's insight:
excerpt: “Right now, the psychological risks are still not completely understood and not completely corrected for,” said chief investigator for the project, Kimberly Binsted, Information and computer science professor from the University of Hawaii at Manoa. “NASA is not going to go until we solve this.” "How do you select and support astronauts for a mission that will last two to three years in a way that will keep them healthy and performing well?” Binsted said.

Madagascar's bark spider (Caerostris darwini) makes up to 82 feet large orb nets, 10 x stronger than Kevlar

Madagascar's bark spider (Caerostris darwini) makes up to 82 feet large orb nets, 10 x stronger than Kevlar | Science, Technology, and Current Futurism | Scoop.it

The web of the Darwin's bark spider (Caerostris darwini), can span some square feet (2.8 square meters) and is attached to each riverbank by anchor threads as long as 82 feet (25 meters).

 

Scientists have found the toughest material made by life yet — the silk of a spider whose giant webs span rivers, streams and even lakes. Spider silks were already the toughest known biomaterials, able to absorb massive amounts of energy before breaking. However, researchers have now revealed the Darwin's bark spider (Caerostris darwini) has the toughest silk ever seen — more than twice as tough as any previously described silk, and more than 10 times stronger than Kevlar.

 

Although scientists have investigated silks from 20-to-30 species of spiders before, most of these were chosen haphazardly — for instance, from researchers' backyards. There are over 40,000 species of spiders and each spider can produce up to seven different kinds of silk. Thus, more than 99.99 percent of spider silks are yet to be explored.

First Photos of Water Ice on Mercury Captured by NASA Spacecraft

First Photos of Water Ice on Mercury Captured by NASA Spacecraft | Science, Technology, and Current Futurism | Scoop.it

The first-ever photos of water ice near Mercury's north pole have come down to Earth, and they have quite a story to tell.

 

The images, taken by NASA's MESSENGER spacecraft (short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging), suggest that the ice lurking within Mercury's polar craters was delivered recently, and may even be topped up by processes that continue today, researchers said.

 

More than 20 years ago, Earth-based radar imaging first spotted signs of water ice near Mercury's north and south poles — a surprise, perhaps, given that temperatures on the solar system's innermost planet can top 800 degrees Fahrenheit (427 degrees Celsius).

Russell R. Roberts, Jr.'s curator insight, October 17, 2:19 AM

A fascinating discovery by NASA's MESSENGER spacecraft, considering that the closest planet to our sun can have surface temperatures reaching 427 degrees C (800 degrees F.)  Evidence suggests that some of this ice was deposited on Mercury fairly recently.  Aloha, Russ.

Marks pointed out that although the resolution of the gigapixel camera is not as high as the best dermatoscope, it is significantly better than normal photography, allows for a larger imaging area than a dermatoscope and could be used for telemedicine, which could make the routine screening available to a larger number of people, even in remote locations. The gigapixel imaging technology is based on the multiscale camera design, which is part of the Defense Advanced Research Projects Agency program "Advanced Wide Field-of-View Architectures for Image Reconstruction and Exploitation."

Experiment makes Schrödinger's cat choose—things can be real, or certain, but not both

Experiment makes Schrödinger's cat choose—things can be real, or certain, but not both | Science, Technology, and Current Futurism | Scoop.it

Experimenting within quantum theory is an extremely complex process, where common intuitions are regularly inverted within shifting reality. Over the years several quantum features and methods of their study have been identified. Now scientists have investigated a new set of assumptions and proposed a novel experiment, to test the consequences of making quantum theory more intuitive.

 

"While quantum theory is the science behind almost all of our technology, its disconnect with our everyday intuitions is still worrisome and actively researched," says lead author Associate Professor Daniel Terno.

 

"How do you find your way in a reality which is shifting, where the opposites are allowed to coexist? Moreover, how do you conduct experiments in it? These are the questions that must be answered when dealing with the floating world of quantum mechanics."

 

Throughout the development of quantum theory, a set of reasonable ideas has led to strange paradoxes, such as the famous Schrodinger's cat, which is neither dead nor alive.

 

Using this wave-particle duality as their starting point, the research team investigated a new and more comprehensible set of assumptions:

 

Every object at any time is really a particle or a wave, but not both (objectivity)If you know enough you can predict everything (determinism)Speed of light is the ultimate limit (locality) 

 

In taking these assumptions and applying them to an experiment, where the measuring device is controlled by a Schrodinger's cat-like state, the research team reached some perplexing paradoxes.

 

"Only after the cat was found to be dead or alive were we able to tell if what we did was to look for a particle or for a wave," says Associate Professor Terno. "Then these three innocent-looking ideas result in predictions that would contradict an experiment. The universe simply does not work like that: you can see things to be real, or certain, but not both."

 

Then the researchers tweaked their initial assumptions, replacing the third assumption with the requirement that how you set your detectors does not affect the system you study before they interact. This tweak lead to another strange result: it is not only that our quantum world is not like that, but such a combination cannot be realized in any universe.

 

"We can just repeat after Alice: things get stranger and stranger"

Spectral Signatures of Reorganised Brain Networks in Disorders of Consciousness

Spectral Signatures of Reorganised Brain Networks in Disorders of Consciousness | Science, Technology, and Current Futurism | Scoop.it
Theoretical advances in the science of consciousness have proposed that it is concomitant with balanced cortical integration and differentiation, enabled by efficient networks of information transfer across multiple scales. Here, we apply graph theory to compare key signatures of such networks in high-density electroencephalographic data from 32 patients with chronic disorders of consciousness, against normative data from healthy controls. Based on connectivity within canonical frequency bands, we found that patient networks had reduced local and global efficiency, and fewer hubs in the alpha band. We devised a novel topographical metric, termed modular span, which showed that the alpha network modules in patients were also spatially circumscribed, lacking the structured long-distance interactions commonly observed in the healthy controls. Importantly however, these differences between graph-theoretic metrics were partially reversed in delta and theta band networks, which were also significantly more similar to each other in patients than controls. Going further, we found that metrics of alpha network efficiency also correlated with the degree of behavioural awareness. Intriguingly, some patients in behaviourally unresponsive vegetative states who demonstrated evidence of covert awareness with functional neuroimaging stood out from this trend: they had alpha networks that were remarkably well preserved and similar to those observed in the controls. Taken together, our findings inform current understanding of disorders of consciousness by highlighting the distinctive brain networks that characterise them. In the significant minority of vegetative patients who follow commands in neuroimaging tests, they point to putative network mechanisms that could support cognitive function and consciousness despite profound behavioural impairment.
