Medical Xpress / New tool can see how different brain cell types work together
When probes are inserted into the brain for research or clinical purposes, the electrical activity of neurons is recorded. These signals can be used to understand how the brain performs certain computations or even to identify ...
Medical Xpress / Overlooked brain damage sets off a chain reaction that could change how neurodegeneration is fought
Damage to white matter in the brain can trigger features associated with neurodegenerative disease, Cambridge researchers have discovered in a new study published in the journal Nature. Until now, it was thought that neurodegenerative ...
Medical Xpress / New clues to hepatitis B species restriction could help build a novel model for studying infection
Some 254 million people live with a chronic hepatitis B (HBV) infection that is often asymptomatic for decades, only to emerge in an advanced stage of disease that turns to fatal cirrhosis or liver cancer in nearly a million ...
Medical Xpress / Can doctors discuss a president's mental health? Why ethics and public risk collide
As the oldest person elected president of the United States, Donald Trump has long faced questions about his health. But is it appropriate for doctors to comment publicly on a president's mental health? In an opinion article ...
Phys.org / Ancient amber reveals a true bug equipped with claws, a highly unusual feature
Amber from the Kachin region of Myanmar has preserved a wealth of fossils, offering insights into the diversity of the Cretaceous fauna of a 100-million-year-old forest ecosystem. The site continues to yield previously unknown ...
Phys.org / How a faster protein-screening tool could strengthen US rare-earth supply chains
To ensure a robust domestic supply chain in the U.S., Lawrence Livermore National Laboratory (LLNL) scientists are using bacterial proteins to separate the rare-earth elements that are ubiquitous in magnets, batteries, and ...
Medical Xpress / Autoantibody map uncovers body-wide immune attacks across Alzheimer's, Parkinson's and MS
Researchers at the University of São Paulo (USP) in Brazil discovered that neurodegenerative diseases, such as Alzheimer's, Parkinson's, and multiple sclerosis, are more complex than previously thought. Their analysis of ...
Phys.org / Turning four into two: How duplicated genomes become diploid again
Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of the process known as rediploidization. ...
Phys.org / Millions of atoms, shifting bonds—new software brings living chemistry into view
Chemical reactions drive life. They ensure that cells obtain energy, proteins perform their functions, and DNA changes under certain conditions. However, many of these processes occur on extremely small scales—so small and ...
Phys.org / Elusive tularemia proteins reveal possible treatment target in rare tick-borne disease
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Symptoms of infection can include fever, swollen lymph nodes, and—in some cases—pneumonia. What ...
Tech Xplore / Excuse me, is that solar panel pointing in the right direction?
On a bright morning, graduate student Jeremy Klotz and professor Shree Nayar walked through upper Manhattan with a tall tripod and a camera that takes 360-degree images. Their route took them to bike docking stations, which ...
Phys.org / Soundwaves settle debate about elusive quantum particle
It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a Majorana fermion, in a quantum spin liquid called ruthenium trichloride. Majoranas are highly sought-after ...
