Scientists push boundaries with high-tech device that turns heat source into readily available energy — here’s how it works
Posted by Genevieve Klien in categories: business, solar power, sustainability
The International Renewable Energy Agency says breakthroughs like this, along with others such as solar panels that work at night or China’s flywheel energy storage project, are key to cutting back on dirty energy use and creating stronger and more reliable power systems.
“Further international cooperation is vital to deliver fit-for-purpose grids, sufficient energy storage and faster electrification, which are integral to move clean energy transitions quickly and securely,” Executive Director of the International Energy Agency Fatih Birol said in an IEA report.

Shrinking AI for Personal Devices: An efficient small language model that could perform better on smartphones
Posted by Natalie Chan in categories: mobile phones, robotics/AI
Large language models (LLMs), such as Open AI’s renowned conversational platform ChatGPT, have recently become increasingly widespread, with many internet users relying on them to find information quickly and produce texts for various purposes. Yet most of these models perform significantly better on computers, due to the high computational demands associated with their size and data processing capabilities.
To tackle this challenge, computer scientists have also been developing small language models (SLMs), which have a similar architecture but are smaller. These models could be easier to deploy directly on smartphones, allowing users to consult ChatGPT-like platforms more easily daily.
Researchers at Beijing University of Posts and Telecommunications (BUPT) recently introduced PhoneLM, a new SLM architecture for smartphones that could be both efficient and highly performing. Their proposed architecture, presented in a paper published on the arXiv preprint server, was designed to attain near-optimal runtime efficiency before it undergoes pre-training on text data.

Discovery of Mitochondrial Mechanism could provide New Options for Treating Inflammatory Diseases
Posted by Natalie Chan in category: biotech/medical
Whether cells in the human body survive or die under stress depends, among other things, on their mitochondria. Scientists at the Faculty of Medicine at the University of Freiburg have now shown that a sudden stop in energy production in mitochondria prevents normal cell death or so-called apoptosis and instead triggers an inflammatory response. The results of this research were published in the journal Immunity.
“We found that mitochondria provide a kind of decision-making aid: they regulate whether a cell undergoes clean, silent apoptosis or releases pro-inflammatory messenger substances,” explains Prof. Dr. Olaf Groß, head of the study, a scientist at the Institute of Neuropathology at the Medical Center—University of Freiburg and a member of the Cluster of Excellence CIBSS—Center for Integrative Biological Signaling Studies at the University of Freiburg.
“This finding helps us to better understand how the body maintains a balance between cell protection and defense mechanisms. This could open up new avenues for the treatment of inflammatory diseases.”

The Architects of Life: Scientists Decipher mRNA’s Secret Blueprint
Posted by Paul Battista in categories: biotech/medical, chemistry
Researchers discovered that the mRNA modification m6A triggers rapid degradation, regulating protein production. This breakthrough could inform drug development to manage protein-related diseases.
Messenger ribonucleic acids (mRNA) are like the architects of our bodies. They carry precise blueprints for building proteins, which are read and assembled by their cellular partners, the ribosomes. Proteins are essential for our survival, as they regulate cell division, bolster the immune system, and make our cells resilient against external threats.
Just like in real-world construction, some cellular blueprints require extra instructions—such as when a protein needs to be produced rapidly or when corrections are needed for a flawed design. In our bodies, this role is fulfilled by RNA modifications. These small chemical changes function like detailed annotations, offering additional guidance to specific parts of the mRNA for optimal protein production.

Scientists Quantified The Speed of Human Thought, And It’s a Big Surprise
Posted by Paul Battista in categories: computing, internet, neuroscience
The speed of the human brain’s ability to process information has been investigated in a new study, and according to scientists, we’re not as mentally quick as we might like to think.
In fact, research suggests our brains process information at a speed of just 10 bits per second. But how is this possible, in comparison to the trillions of operations computers can perform every second?
Research suggests this is the result of how we internally process thoughts in single file, making for a slow, congested queue.

Your Poop Schedule Says a Lot About Your Overall Health, Study Finds
Posted by Paul Battista in categories: biotech/medical, health, neuroscience
A study published in Cell Reports Medicine reveals that bowel movement frequency significantly influences physiology and long-term health, with the best outcomes linked with passing stools once or twice a day.
Previous research has suggested associations between constipation and diarrhea with higher risks of infections and neurodegenerative conditions, respectively.
But since these findings were observed in sick patients, it remained unclear whether irregular bathroom visits were the cause or result of their conditions.
