Green hydrogen, a source of clean energy that can be generated without using fossil fuels, has recently gained immense attention as it can be potentially used to promote carbon neutrality. Korean researchers have succeeded in improving the efficiency of unitized regenerative fuel cells that can be used to efficiently produce green hydrogen and generate power.

A recent study by Nagoya University researchers revealed that microRNAs in urine could be a promising biomarker to diagnose brain tumors. Their findings have indicated that regular urine tests could help early detection and treatment of brain tumors, possibly leading to improved patient survival.

Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye. The peptides might someday be used to treat degenerative retinal diseases, such as age-related macular degeneration (AMD).

How do supermassive black holes in the early universe originate? A team led by a theoretical physicist at the University of California, Riverside, has come up with an explanation: a massive seed black hole that the collapse of a dark matter halo could produce.

A study led by University of Minnesota physics researchers has discovered that a unique superconducting metal is more resilient when used as a very thin layer.

A new approach to studying conjugated polymers made it possible for an Army-funded research team to measure, for the first time, the individual molecules' mechanical and kinetic properties during polymerization reaction. The insights gained could lead to more flexible and robust soft electronic materials, such as health monitors and soft robotics.

The long relationships between stars and the planets around them - including the Sun and the Earth - may be even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA's Chandra X-ray Observatory.

Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. UC Berkeley and Stanford scientists have developed a new type of sensor that employs a sheet of graphene to get a continuous measure of electric field in these tissues. Electric fields change graphene's reflectance. The physicists found a way to amplify and measure the changes caused by action potentials in a beating embryonic chicken heart.
