New findings support the view that hyperactive immune cells in the brain can have a protective effect in the course of neurodegenerative diseases.

While the word ‘mutation’ may conjure up alarming notions, a mutation in brain immune cells serves a positive role in protecting people against Alzheimer’s disease. Now biologists have discovered the mechanisms behind this crucial process.

With the early assessment of sustainable, newly developed chemicals and products it is possible to assess a potential risk of toxic substances being released at a later point in product cascades. In the course of the study the toxicity of sustainable b…

Several dozen small impact craters, 10–70-m in size, have been discovered in southeastern Wyoming. A team of U.S. and German geoscientists found these ancient craters in exposed sedimentary layers from the Permian period (280 million years ago). After…

Researchers have uncovered a new pathway that helps explain how consuming too much alcohol causes damage to the liver, specifically mitochondrial dysfunction in alcohol-associated liver disease.

Coils and stents less invasively repair brain aneurysms, but are they superior to clips implanted during surgery? A study compares the treatments.

A new study shows how a particular molecule, produced by gut bacteria, affects brain function and promotes anxiety-like behaviors in mice.

Following up on a 2018 study that identified an epigenetic modifier known as histone deacetylase 11 (HDAC11) as a potential therapeutic target for treating obesity and diabetes, researchers have published new research that finds HDAC11 regulates G prot…

Astrophysicists report how, when tiny galaxies collide with bigger ones, the bigger galaxies can strip the smaller galaxies of their dark matter — matter that we can’t see directly, but which astrophysicists think must exist because, without its gravi…

The brain has neurons that fire specifically during certain mathematical operations. The findings indicate that some of the neurons detected are active exclusively during additions, while others are active during subtractions. They respond in the same …

Climate change threatens to destroy invaluable heritage sites and traditions in marginalized countries — but empowering local people is key to adaptation. Locally led research and more equitable research funding are needed to address the true potentia…

Bioengineershave found a way to radically increase the efficiency of single-cell RNA-sequencing, a powerful tool that can ‘read’ the genetic profile of an individual cell.

A new study found in a living embryo that the back ends of moving cell groups push the group forward, with implications for how organs form and cancer spreads.

Minor everyday rises in blood pressure due to short-term stressors can be linked to a brain area that controls conscious and learned motor skills. This discovery paves the way for a chance to influence the rises in blood pressure and, in the long run, …

Scientists have created the first ever 2D map of the Overhauser field in organic LEDs, shedding light on the challenges we face in designing accurate quantum-based technologies.

A research team has developed a new algorithm to measure entanglement entropy, advancing the exploration of more comprehensive laws in quantum mechanics, a move closer towards actualization of application of quantum materials.

Nanomaterials have revolutionized the world of cancer therapy, and plant-derived nanoparticles have the added advantage of being cost-effective and easy to mass produce. Researchers have recently developed novel corn-derived bionanoparticles for target…

Researchers have developed an automated technique that uses satellite imagery to determine when swine waste lagoons were constructed, allowing researchers to determine the extent to which these facilities may have affected environmental quality.

New research has broken an important ‘barrier’ in neutrino physics which is relevant for both particle physics and cosmology. A new upper limit of 0.8 electronvolt (eV) for the mass of the neutrino has been obtained. This first push into the sub-eV mas…

Researchers report on a novel disorder-engineering technique for inorganic solar cells that achieves a record-breaking power conversion efficiency.
