The BBC claims that researchers have found the first evidence for string theory, citing a recent discovery of long-wavelength gravitational waves that might indicate the existence of so-called “cosmic strings.” Crazier still, they think that this could allow time travel! But do these gravitational waves actually mean that cosmic strings exist? And what, if anything, does it have to do with time travel?

Combining graphene and nanodiamonds for better microplasma devices

Posted by in categories: biotech/medical, chemistry, nanotechnology

Microplasma devices are incredibly versatile tools for generating and sustaining plasmas on micro-and millimeter scales. The latest advances in nanotechnology now promise to expand their range of applications even further but, so far, this progress has been held back by the limited stability of some nanostructures at the extreme temperatures required to sustain many plasmas.

In a recent study published in Fundamental Plasma Physics, K J Sankaran and colleagues at the CSIR Institute of Minerals and Materials Technology, Bhubaneswar, India, overcome this challenge by decorating sheets of graphene with more stable nanodiamonds—that is, diamonds with diameters smaller than about 100 nm—allowing them to endure far more .

This combined material could expand the use of microplasma devices across a diverse array of useful applications, such as sterilizing and healing wounds, analyzing chemicals, and displaying images.

New blood test could tell if you’ll get Alzheimer’s years from now

Posted by in categories: biotech/medical, neuroscience

A new blood test may be key to diagnosing Alzheimer’s disease before the condition becomes debilitating.

Neuroscientists at New York University collected and analyzed the blood samples of 125 subjects for acetyl-L-carnitine (ALC) and free-carnitine, two markers essential for brain function.

These substances help to power cells, as well as regulate glutamate, which is involved in most brain activities.

Posted by in categories: biological, robotics/AI, wearables

Might Artificial Intelligence be the ideal lab assistant? Stefan Harrer delves into the revolutionary role of generative AI in science. He reveals how AI agents are not just tools but transformative partners for scientists enabling them to achieve breakthroughs in biology and beyond, heralding a new era of scientific discovery and innovation. This inspiring talk highlights the potential for AI to redefine the boundaries of the scientific method and our understanding of life. Dr Stefan Harrer is the Director of AI for Science at CSIRO, Australia’s national science agency. He is on a mission to revolutionise scientific discovery by harnessing the power of AI agents. In senior leadership roles at IBM Research, he led groundbreaking work on AI-driven epilepsy management and developed the world’s first AI-powered wearable for seizure prediction. An inventor with 73 granted patents, a passionate advocate for ethical AI, and a mentor and advisor to startups and governments, Stefan inspires the next frontier of AI innovation and use. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Scientists achieve record-breaking solar energy system: ‘Only possible by combining two major breakthroughs’

Posted by in categories: solar power, sustainability

Researchers created a groundbreaking solar panel system that could increase the total amount of clean energy solar panels can generate.

Solar energy is a promising energy source that is significantly cleaner than traditional dirty fuels. However, current solar panels often require high-temperature manufacturing processes that generate significant amounts of carbon. On top of that, traditional solar panels absorb only small portions of infrared and ultraviolet light, meaning chunks of sunlight don’t get converted into usable energy.

Why Alzheimer’s scientists are rethinking the amyloid hypothesis

Posted by in categories: biotech/medical, health, neuroscience

For decades, scientists have been trying to develop therapeutics for people living with Alzheimer’s disease, a progressive neurodegenerative disease that is characterized by cognitive decline. Given the global rise in cases, the stakes are high. A study published in The Lancet Public Health reports that the number of adults living with dementia worldwide is expected to nearly triple, to 153 million in 2050. Alzheimer’s disease is a dominant form of dementia, representing 60 to 70 percent of cases.

Recent approvals by the Food and Drug Administration have focused on medications that shrink the sticky brain deposits of a protein called amyloid beta. The errant growth of this protein is responsible for triggering an increase in tangled threads of another protein called tau and the development of Alzheimer’s disease — at least according to the dominant amyloid cascade hypothesis, which was first proposed in 1991.

Over the past few years, however, data and drugs associated with the hypothesis have been mired in various controversies relating to data integrity, regulatory approval, and drug safety. Nevertheless, the hypothesis still dominates research and drug development. According to Science, in fiscal year 2021 to 2022, the National Institutes of Health spent some $1.6 billion on projects that mention amyloids, about 50 percent of the agency’s overall Alzheimer’s funding. And a close look at the data for recently approved drugs suggests the hypothesis is not wrong, so much as incomplete.
