Sharing the Future with Artificial Intelligence
by Aurametrix team in Aurametrix Blog
Artificial intelligence has reached a buzzword utopia as it seems everyone is talking about self-driving cars, delivery drones and virtual assistants with human-like "intelligence." Some believe this new era of AI will make the American Dream universally accessible, enabling early retirement in bucolic settings. Others are concerned about a greater inequality created by a jobless future.... Read more »

Using Discourse Analysis to Assess Cognitive Decline
by The Neurocritic in The Neurocritic
Figure from Gauthier et al. (2005).
Alzheimer's Disease (AD) and other dementias are progressive neurodegenerative conditions that unfold over time. Subtle symptoms such as forgetfulness and word finding problems may progress to mild cognitive impairment (MCI), and then escalate to full-blown dementia. Recent efforts to classify prodromal states have included automated analysis of spontaneous... Read more »

More than Meets the Eye
by Aurametrix team in Aurametrix Blog
Eyeglasses are almost as old as the civilization itself. They have not changed much since Benjamin Franklin's bifocals in the 18th century. Nor were they made obsolete by laser surgery and contacts. Still, eyeglass technology leaves much to be desired. But new technologies are unfolding before our eyes. ... Read more »

Why we have not met Aliens yet?
by Usman Paracha in SayPeople
A huge of number of people keeps on thinking about the existence of some other intelligent beings in the universe but still we have not met any aliens. Why?
Earth is rare
Earth is special planet
One of the reasons that we have not met aliens is that Earth is rare and there is nothing just like Earth in the universe. In this regard, Paleontologist Peter Ward and astronomer Donald Brownlee presented the Rare Earth Hypothesis about 17 years ago.
According to the Rare Earth Hypothesis, t........ Read more »

Fusion and sex in protocells & the start of evolution
by Artem Kaznatcheev in Evolutionary Games Group
In 1864, five years after reading Darwin’s On the Origin of Species, Pyotr Kropotkin — the anarchist prince of mutual aid — was leading a geographic survey expedition aboard a dog-sleigh — a distinctly Siberian variant of the HMS Beagle. In the harsh Manchurian climate, Kropotkin did not see competition ‘red in tooth and claw’, […]... Read more »

Doc versus machine
by Dr. Jekyll in Lunatic Laboratories
Increasingly powerful computers using ever-more sophisticated programs are challenging human supremacy in areas as diverse as playing chess and making emotionally compelling music. But can digital diagnosticians match, or even outperform, human physicians? The answer, according to a new study, is "not quite."

New sensor material could enable more sensitive readings of biological signals
by Dr. Jekyll in Lunatic Laboratories
High-tech prosthetics, computers that are controlled by thought, the ability to walk or even move again, these are just a few of the promises of technology. Unfortunately, while the tech is -- mostly -- up to the challenge, getting the biology side of things to cooperate has been difficult at best, but that could change. Now, scientists have created a material that could make reading biological signals, from heartbeats to brainwaves, much more sensitive.

Concentrating on the social billions
by Dr. Jekyll in Lunatic Laboratories
Using online social media does not lead to long-term problems with our ability to concentrate, according to new research. We are social animals, so it is really no surprise that billions of us now use online tools to communicate, educate and inform each other. The advent of social media and social networking has nevertheless been phenomenally rapid.

First demonstration of brain-inspired device to power artificial systems
by Dr. Jekyll in Lunatic Laboratories
New research has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain. Artificial neural networks (ANNs) exhibit learning abilities and can perform tasks which are difficult for conventional computing systems, such as pattern recognition, on-line learning and classification.

A trio of researchers has found off-the-shelf AI software can be used to identify people in blurred or pixilated images. The researchers have uploaded a paper describing the experiments they carried out with AI software identification of people or other items in blurred out images, what they found and reveal just how accurate they found it could be.

Food waste could store solar and wind energy, or there's the obvious...
by Dr. Jekyll in Lunatic Laboratories
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.

Social connectedness can increase suicide risk
by Dr. Jekyll in Lunatic Laboratories
Community characteristics play an important role in perpetuating teen suicide clusters and thwarting prevention efforts, according to a new study by sociologists who examined clusters in a single town. The study illustrates how the homogeneous culture and high degree of social connectedness of a community can increase suicide risk, particularly among teenagers.

Body heat as a power source
by Dr. Jekyll in Lunatic Laboratories
Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Chinese scientists are now aiming to obtain the necessary energy from body heat by introducing a flexible, wearable thermocell based on two different gel electrolytes.

Can life be brought to celestial bodies outside our solar system, which are not permanently inhabitable? A new essay that has been published is trying to deal with this question. Over the last several years, the search for exoplanets has shown that very different types exist leading to new questions and a variety of possible answers.

Music from Your Brain
by The Neurocritic in The Neurocritic
The journal Brain has a new review on the history of converting the electroencephalogram (EEG) into sound (Lutters & Koehler, 2016). The translation of data into sound, known as sonification, has been applied to brain waves since the 1930s. In addition to early scientific and medical applications, sonification of the EEG has been used in the field of experimental music.In 1965, physicist Edmond Dewan and composer Alvin Lucier collaborated on Music for the Solo Performer:Sitting on a cha........

'I miss you so much': How Twitter is broadening the conversation on death and mourning
by Dr. Jekyll in Lunatic Laboratories
Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes. But social media is redefining how people grieve, and Twitter in particular -- with its ephemeral mix of rapid-fire broadcast and personal expression -- is widening the conversation around death and mourning.
