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.

social media

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.

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.

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.

genie you're free

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.

In this digital age, with phones at our fingertips, you would think that access to constant communication would make us feel closer to one another. But a new study shows that may not be the case. In fact, cell phone use might actually lead to feeling less socially connected, depending on your gender or cell phone habits.

Your friends have more friends than you do

No matter how smart and funny you think you are, those you follow on Twitter really do have a larger following than you. And the same holds true for Facebook. But there is no reason to feel badly about any of this. According to the research, it is all due to the inherently hierarchical nature of social media networks, where, in the social hierarchy of connections, people mostly either follow up or across; they rarely follow down.

Tablet and laptop users beware. Using digital platforms such as tablets and laptops for reading may make you more inclined to focus on concrete details rather than interpreting information more abstractly, according to a new study. The findings serve as another wake-up call to how digital media may be affecting our likelihood of using abstract thought.

The whole of human intelligence, right at your fingertips. Sure it might not make the layman an engineer or physicist, but if we want to learn about a particular topic the internet can give us that information. But you better hold on tight before you lose it. New research finds retweeting or otherwise sharing information creates a “cognitive overload” that interferes with learning and retaining what you’ve just seen.

As a society we have become incredibly reliant on technology, from spell check to GPS, we are slowly being replaced by computers. Need more proof, a computer can routinely beat us at chess, an AI wrote portions of a book that went on to almost win a writing contest, and if you want scary robotics enter Boston dynamics spot.  So the question is,  have we outlived our place in the world? Not quite. Welcome to the front line of research in cognitive skills, quantum computers and gaming.

Last month, we spoke of our vision of the future of humanity here at the lab. It makes sense that humanity would one-day step away from the static, non-living computer constructs we have designed. Moving us instead towards an organic alternative, one that can be readily repaired, replaced, or changed. While we cannot pretend to know what the future may hold, a new discovery helps bolster the stance we presented.
