The University of Liverpool has reported a significant advancement in engineering biology and clean energy. A team of researchers has developed an innovative light-driven hybrid nanoreactor that merges natural efficiency with cutting-edge synthetic precision to produce hydrogen—a clean and sustainable energy source.

Published in ACS Catalysis, the study demonstrates a pioneering approach to artificial photocatalysis, addressing a critical challenge in using solar energy for fuel production. While nature’s photosynthetic systems have evolved for optimal sunlight utilisation, artificial systems have struggled to achieve comparable performance.

The hybrid nanoreactor is the product of a novel integration of biological and synthetic materials. It combines recombinant α-carboxysome shells—natural microcompartments from bacteria—with a microporous organic semiconductor. These carboxysome shells protect sensitive hydrogenase enzymes, which are highly effective at producing hydrogen but prone to deactivation by oxygen. Encapsulating these enzymes ensures sustained activity and efficiency.

Middlemen get a bad rap for adding cost and complications to an operation. So, eliminating the go-betweens can reduce expense and simplify a process, increasing efficiency and consumer happiness.

James Dahlman and his research team have been thinking along those same lines for stem cell treatments. They’ve created a technique that eliminates noisome middlemen and could lead to new, less-invasive treatments for blood disorders and genetic diseases. It sidesteps the discomfort and risks of current treatments, making life easier for patients.

“This would be an alternative to invasive hematopoietic stem cell therapies—we could just give you an IV drip,” said Dahlman, McCamish Early Career Professor in the Wallace H. Coulter Department of Biomedical Engineering. “It simplifies the process and reduces the risks to patients. That’s why this work is important.”

It’s estimated that anywhere from three to seven percent of school-age children may have dyslexia, a neurodevelopmental issue that affects reading, spelling, and writing. There are different ideas about why dyslexia occurs, although they relate to dysfunction in brain networks, and are likely due to multiple causes in affected individuals; the disorder may not have a singular underlying cause. Neuroimaging studies of dyslexic individuals have produced inconsistent results.

Since dyslexia has a heritable, and therefore, genetic component, scientists wanted to know more about how genetics and brain mapping could reveal more about the pathology of dyslexia. A new study has shown that carriers of genetic variants that increase the risk of dyslexia also have changes in brain structure, which occur in areas that are related to language, motor coordination, and vision. The findings have been reported in Science Advances.

The breakthrough marks a promising target for drug therapies that slow, possibly reverse, the disease’s development

NEW YORK, NY, December 23, 2024 — Researchers with the CUNY ASRC have unveiled a critical mechanism that links cellular stress in the brain to the progression of Alzheimer’s disease (AD). The study, published in the journal Neuron, highlights microglia, the brain’s primary immune cells, as central players in both the protective and harmful responses associated with the disease.

Microglia, often dubbed the brain’s first responders, are now recognized as a significant causal cell type in Alzheimer’s pathology. However, these cells play a double-edged role: some protect brain health, while others worsen neurodegeneration. Understanding the functional differences between these microglial populations has been a research focus for Pinar Ayata, the study’s principal investigator and a professor with the CUNY ASRC Neuroscience Initiative and the CUNY Graduate Center’s Biology and Biochemistry programs.

As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier.

But University of Michigan researchers have discovered that the rate at which these large structures grow is slower than predicted by Einstein’s Theory of General Relativity.

They also showed that as dark energy accelerates the universe’s global expansion, the suppression of the cosmic structure growth that the researchers see in their data is even more prominent than what the theory predicts. Their results are published in Physical Review Letters.

Could Our Universe Have Been Born from a Black Hole?

Black holes are among the most mysterious and fascinating objects in the universe, known for their powerful gravitational pull that nothing can escape. Interestingly, if you were to compress all the matter in the universe into a single point, you would create a black hole roughly the size of the universe itself. While we do not live inside a black hole, the similarities between black holes and our universe raise intriguing questions about their connection.

Event horizons: no escape in both cases.

A new study from Northwestern Medicine reports that, much like a conductor harmonizes various instruments in an orchestra to create a symphony, breathing synchronizes hippocampal brain waves to enhance memory during sleep.

This is the first time breathing rhythms during sleep have been linked to these hippocampal brain waves — called slow waves, spindles, and ripples — in humans. Scientists knew these waves were linked to memory but their underlying driver was unknown.

Exercise improves cognitive performance for over 24 hours, especially when paired with good sleep. A study of older adults links physical activity and deep sleep to better memory, highlighting the importance of an active lifestyle for brain health.

Exercise provides a short-term boost to brain function that can last throughout the next day, according to a new study by researchers at University College London (UCL).

Earlier research conducted in controlled laboratory settings revealed that cognitive performance improves in the hours following exercise. However, the duration of these benefits remained unclear.

Quantum teleportation, once confined to the pages of science fiction, is steadily becoming a tangible scientific achievement. Advances in quantum mechanics over the last decade have transformed teleportation from a theoretical concept into an experimental reality.

These breakthroughs have revealed innovative methods for transmitting information instantaneously over vast distances, offering transformative possibilities for computing, communication, and cryptography. Scientists are now closer than ever to bridging the gap between imagination and reality in this cutting-edge field.

At its core, teleportation in the quantum world isn’t about physically transporting objects or people, as popularized by franchises like Star Trek. Instead, it involves transmitting quantum states—essentially the fundamental properties of particles like electrons or photons—without physical movement of the particles themselves.
