New method for real-time detection of neural oscillation bursts

Neural oscillations - also known as brainwaves - are important carriers of information in the brain. Researchers are increasingly coming to view them less as sustained oscillations and more as transient bursts.

A simple, straightforward approach to protein modification

Proteins are essential parts of organisms; thus, they are widely used in medicine, biology and chemistry. Enhancing their inherent properties by adding functional molecules to their structures is a common and important step in many fields.

New study describes inflammatory reaction in lab-developed human astrocytes

Astrocytes are neural cells with many important functions in the nervous system. The inflammation of these cells occurs in brain infections and neurodegenerative disorders, a process called astrogliosis.

Molecular study defines the contributions of key genes, proteins to endometrial cancer

The most comprehensive molecular study of endometrial cancer to date has further defined the contributions of key genes and proteins to the disease, say its authors.

New study may lead to better treatments for Parkinson's disease

Parkinson's disease is a long-term (chronic) neurological condition that affects around 12,000 people in Ireland and between 7 and 10 million people worldwide. The disease affects the way the brain co-ordinates body movements like walking and talking, but cognitive abilities are also affected.

Study explains how certain mutations can shorten biological clock timing

A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme "morning larks" because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night.

Macrophages consult with neighbors before making decisions

Many people consult their friends and neighbors before making a big decision. It turns out that cells also are consulting their neighbors in the human body.

Diets high in fat and protein exacerbate C. diff infections in mice

Popular diets low in carbs and high in fat and protein might be good for the waistline, but a new UNLV study shows that just the opposite may help to alleviate the hospital-acquired infection Clostridioides difficile.

New therapeutic compounds could fight against brain-eating amoebae

Brain-eating amoebae can cause particularly harmful forms of encephalitis, and more than 95% of people who develop these rare but devastating infections die.

Vapers exhibit similar chemical changes in their genome as smokers

Biologically important changes in DNA seen in smokers are also being found in people who vape, according to a new study published in the journal Epigenetics.

Study explores how some mammals postpone development of their embryos

How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive enigma, which can occur in more than 130 species of mammals as well as in some marsupials.

New hydrogenation process could lead to safe hydrogen gas

Safe and environmentally-friendly hydrogen gas on demand could be on the horizon following a new "hydrogenation" chemical process in development at The City College of New York. Led by Mahesh K. Lakshman, the research uniquely bypasses the need for an external source of hydrogen gas to accomplish a wide range of hydrogenations.

Researchers identify involvement of certain cortical areas in the loss of control over food intake

Researchers at UPF, in collaboration with researchers from the University of Mainz (Germany), the Center for Genomic Regulation, Instituto Cajal, Johannes Gutenberg University (Germany), the Autonomous University Barcelona and Hospital del Mar have identified for the first time the involvement of certain cortical areas in the brain in the loss of control over food intake.

Experimental fingerprint test can accurately identify traces of cocaine on human skin

An experimental fingerprint detection approach can identify traces of cocaine on human skin, even after someone has washed their hands - and the test is also smart enough to tell whether an individual has actually consumed the class A drug, or simply handled it.
