Researchers have developed an optical system that accurately measures the flow of extraordinarily tiny amounts of liquids -- as small as 10 billionths of a liter (nanoliters) per minute.

Gallium nitride, a semiconductor that revolutionized energy-efficient LED lighting, could also transform electronics and wireless communication, thanks to a new discovery.

Neurotoxocarosis (NT) occurs in humans when larvae of the Toxocara roundworm migrate into the central nervous system. That infection is accompanied by a complex molecular signaling cascade, including changes to anti-infl...

The Global Program to Eliminate Lymphatic Filariasis delivers mass drug administration to 500 million people each year, and adverse events are common following treatment. Now, researchers have reported that certain chang...

The World Health Organization has made it a goal to eliminate human rabies deaths due to dog bites by the year 2030. An increase in dog rabies vaccination rates decreases dog rabies cases, human exposure, and human death...

The powerhouse of the cell, the mitochondria, provides energy for cellular functions. But those activities can become disturbed when chronic stress leads to anxiety symptoms in mice and humans.

In response to seizures, the endoplasmic reticulum (ER), a network of flattened tubes in the cell that packages and transports proteins, triggers a stress response that reduces brain activity and seizure severity. The ne...

For the last 60 million years, fungus-growing ants have farmed fungi for food. In their cultivation of those fungi, they've successfully relied on bacteria-produced antimicrobial ingredients to protect their crops from o...

You'd expect excessive athletic training to make the body tired, but can it make the brain tired too? A new study suggests that the answer is 'yes.'

Investigators have pinpointed a molecular defect that seems almost universal among patients with Parkinson's disease and those at a high risk of acquiring it.

A new imaging method follows young neurons in a developing embryo as they progress from a messy jumble of cells into a coordinated control center. The approach lets scientists track development and emerging cell function...

A cluster of interacting proteins that are active in both human cancers and Tasmanian devil facial tumours, may give clues to how cancers evade the immune system, according to a new study.

Researchers have developed a superior method to describe the very earliest effects that Alzheimer's Disease proteins have on the properties of brain cells.

In a study of 115,803 individuals, the authors have identified 233 sites or loci in the human genome that contribute to the onset of MS. This is the largest study to date in MS.

Tea bags made of plastic can release billions of microplastics into our bodies. (Credit: AnikonaAnn/Shutterstock) There's a new trend in tea -- out with the old, flat paper tea bags and in with the pyramid-shaped mesh ba...

A new discovery about pancreatic cancer sheds light on how the cancer fuels its growth and may help explain how promising cancer drugs work -- and for whom they will fail.

Oral health is a critical component to overall health for all ages, but according to dental and medical experts, vigilance is especially critical for the elderly.

Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? Scientists have now identified the neural circuit in the brain of fruit flies which makes them perform at their b...

A randomized clinical trial of targeted, high-dose radiation for men with oligometastatic prostate cancer has shown the treatment to be an effective and safe option for patients who wish to delay hormone-suppression ther...

Researchers have identified the brain mechanism linking chronic pain and depression in rats. Their research could lead to the development of new treatments for chronic pain and depression.
