Medical Xpress / Brain chemistry can reactivate or suppress dormant HIV
Human immunodeficiency virus (HIV) infections are still fairly common and an estimated 40 million people worldwide are currently living with this condition. The HIV virus attacks the body's immune system and thus makes those ...
Medical Xpress / Gut bacteria may play role in bipolar depression by directly influencing brain connectivity
Bipolar disorder (BD) is a psychiatric disorder characterized by extreme mood changes. Individuals diagnosed with BD typically alternate between periods of high energy, euphoria, irritability and/or impulsivity (i.e., manic ...
Phys.org / Converting CO₂ into valuable chemicals in acidic environments: Iodide ions unlock efficient ethylene production
The emission of carbon dioxide (CO₂) is one of the primary factors contributing to air pollution and climate change on Earth. In recent years, energy engineers have thus been trying to develop systems that could reduce the ...
Medical Xpress / How brain tumor cells influence neurons and vice versa
Gliomas are cancers that originate directly in the brain, instead of spreading to the brain from other parts of the body. These cancers cannot be cured with conventional cancer treatments, as they spread into healthy brain ...
Phys.org / Controlling exciton flow in moiré superlattices: New method leverages correlated electrons
Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition ...
Tech Xplore / Ionic liquids slow perovskite degradation: Solar cells retain 90% performance at 90°C
Solar cells, devices that can generate electricity from sunlight, are already helping to reduce fossil fuel emissions in many countries worldwide. In recent years, energy engineers have been assessing the potential of materials ...
Medical Xpress / The role of neuroinflammation in progressive multiple sclerosis
Multiple sclerosis (MS) is a disorder that prompts the body's immune system to attack myelin, the protective sheath covering nerve cells in the brain, optic nerve and spinal cord. This can in turn result in vision impairments, ...
Medical Xpress / Rethinking recurrent brain activity: Core neurons provide an alternative explanation
Neuroscientists have been trying to understand how the human brain supports numerous advanced capabilities for centuries. The cerebral cortex, the outer layer of the brain, is now known to be responsible for many of these ...
Phys.org / Turning plastic waste into valuable chemicals with single-atom catalysts
The rapid accumulation of plastic waste is currently posing significant risks for both human health and the environment on Earth. A possible solution to this problem would be to recycle plastic waste, breaking it into smaller ...
Phys.org / Good listeners connect more easily with strangers, study finds
With many people now heavily relying on electronic devices to communicate with others, connecting on a deeper level with others, particularly face-to-face, can prove challenging. Recent nationwide surveys and psychological ...
Medical Xpress / Study examines oligodendrocyte dynamics throughout the progression of multiple sclerosis
Multiple sclerosis (MS) is a chronic autoimmune disease characterized by the disruption of nerve signals and various associated neurological symptoms, ranging from vision problems to numbness, weakness, fatigue and cognitive ...
Phys.org / Archimedean screw inspires new way to encode chirality into magnetic materials
In physics and materials science, the term "spin chirality" refers to an asymmetry in the arrangement of spins (i.e., the intrinsic angular momentum of particles) in magnetic materials. This asymmetry can give rise to unique ...
Tech Xplore / Robotic arm successfully learns 1,000 manipulation tasks in one day
Over the past decades, roboticists have introduced a wide range of systems that can effectively tackle some real-world problems. Most of these robots, however, often perform poorly on tasks that they were not trained on, ...
Medical Xpress / People's facial mimicry predicts their choices, study finds
In social situations, humans often copy the facial expressions of others who they are interacting with. This phenomenon, known as facial mimicry, is widely reported and has been linked to social connection and an empathic ...
Phys.org / Subtle twist in materials prompts surprising electromagnetic behavior
Materials react differently to electric and magnetic fields, and these reactions are known as electromagnetic responses. In many solid materials, unusual electromagnetic responses have been known to only emerge when specific ...
