New Synapse-like Phototransistor

 Ground- and excited-state charge transfer in bilayer NC/SWCNT heterojunctions.

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles.

The structures rely on a new type of semiconductor — metal-halide perovskites — which have proven to be highly efficient at converting sunlight into electrical energy and shown tremendous promise in a range of other technologies.

“In general, these perovskite semiconductors are a really unique functional system with potential benefits for a number of different technologies,” said Jeffrey Blackb...

The Enzyme that could help Curb Chronic Kidney Disease

University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.

This enzyme, NEDD4-2, is critical for kidney health, says UniSA Centre for Cancer Biology scientist Dr Jantina Manning in a new paper published this month in Cell Death & Disease.

The early career researcher and her colleagues, including 2020 SA Scientist of the Year Professor Sharad Kumar, have shown in an animal study the correlation between a high salt diet, low levels of NEDD4-2 and advanced kidney disease.

While a high salt diet can exacerbate some forms of kidney disease, until now, researchers did not realise that NEDD4-2 plays a role in promoting this salt-induced k...

One Cup of Leafy Green Vegetables a Day Lowers Risk of Heart Disease

New ECU research has shown eating one cup of nitrate-rich vegetables each day significantly reduces the risk of heart disease

New Edith Cowan University (ECU) research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.

The study investigated whether people who regularly ate higher quantities of nitrate-rich vegetables, such as leafy greens and beetroot, had lower blood pressure, and it also examined whether these same people were less likely to be diagnosed with heart disease many years later.

Cardiovascular diseases are the number one cause of death globally, taking around 17.9 million lives each year.

Researchers examined data from over 50,000 people residing in Denmark taking part in the...

Researchers have demonstrated how two interfering photons can bunch into various shapes. These complex shapes are beneficial for quantum technologies, such as performing fast photonic quantum computations and safe data transfer. The method opens new possibilities also for creating enhanced measurement and sensing techniques.

As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field...
