Tell-tale protein fragment discovered in Alzheimer’s patients could be basis for blood test

Posted by in categories: biotech/medical, neuroscience

A protein fragment from the brain could be used to track progression of Alzheimer’s disease. The tell-tale fragment of tau protein was detectable in the cerebrospinal fluid (CSF) of patients with the disease, and researchers now hope to develop a blood test using it.

Alzheimer’s is a disease of errant protein aggregates that include amyloid plaques and then later tau tangles. ‘Amyloid plaques begin to form about 10 to 20 years before the first symptoms of Alzheimer’s,’ says Randall Bateman, a neurologist at Washington University School of Medicine who helped lead the study. ‘Whereas tau tangles begin once the symptoms begin.’

Studies in two patient groups, each with hundreds of people, revealed that levels of the fragment in the CSF were indicative of tau clumps in the brain seen on imaging and were linked to symptoms of cognitive decline.

Is this hat conscious? | Ben Goertzel on consciousness, panpsychism, and AGI | Big Think

Is this hat conscious?

Join Big Think Edge for exclusive video lessons from top thinkers and doers:

Panpsychism is the idea that there is an element of consciousness in everything in the universe. The theory goes like this: You’re conscious. Ben Goertzel is conscious. And his hat is conscious too. What if consciousness isn’t about the brain at all, but it’s as inherent to our universe as space-time?“Now, panpsychism, to me, is not even that interesting, it’s almost obvious — it’s just the foundation, the beginning for thinking about consciousness… ” says Goertzel. It’s what comes after that excites him, like the emerging technology that will let us connect our minds to bricks, hats, earthworms, other humans, and super AGIs like Sophia, and perhaps glimpse at the fabric of consciousness. Goertzel believes brain-brain interfacing and brain-computer interfacing will unfold in the coming decades, and it’s by that means that we may finally crack the nut of consciousness to discover whether panpsychism makes any sense, and to learn why humans are so differently conscious than, for example, his hat.

Software system can find, track moving objects as small as a pixel

Posted by in categories: computing, drones, satellites, security, surveillance

Remember what it’s like to twirl a sparkler on a summer night? Hold it still and the fire crackles and sparks but twirl it around and the light blurs into a line tracing each whirl and jag you make.

A new patented software system developed at Sandia National Laboratories can find the curves of motion in streaming video and images from satellites, drones and far-range security cameras and turn them into signals to find and track moving objects as small as one . The developers say this system can enhance the performance of any remote sensing application.

“Being able to track each pixel from a distance matters, and it is an ongoing and challenging problem,” said Tian Ma, a computer scientist and co-developer of the system. “For physical security surveillance systems, for example, the farther out you can detect a possible threat, the more time you have to prepare and respond. Often the biggest challenge is the simple fact that when objects are located far away from the sensors, their size naturally appears to be much smaller. Sensor sensitivity diminishes as the distance from the target increases.”

New device turns sunlight into hydrogen with record efficiency

Posted by in categories: solar power, sustainability

As we strive towards a more sustainable future, it’s becoming increasingly important to find innovative ways to decarbonize industry and facilitate clean energy storage.

One promising approach is the manufacture of valuable products and fuels using available, low-cost feedstocks like water, carbon dioxide, nitrogen, and solar energy. By harnessing the power of these abundant resources, we can reduce our reliance on fossil fuels and move towards a cleaner, more sustainable energy future.

In a similar effort, Rice University engineers have developed a device that can turn sunlight into hydrogen with record-breaking efficiency – a significant step forward for clean energy. The device combines next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective, and scalable device.
