Computer scientists set benchmarks to optimize quantum computer performance

Computer scientists have shown that existing compilers, which tell quantum computers how to use their circuits to execute quantum programs, inhibit the computers' ability to achieve optimal performance. Specifically, their research has revealed that improving quantum compilation design could help achieve computation speeds up to 45 times faster than currently demonstrated.

A light bright and tiny: Scientists build a better nanoscale LED

A new design for light-emitting diodes achieves a dramatic increase in brightness as well as the ability to create laser light -- characteristics that could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times over conventional submicron-sized LED designs.

Watching changes in plant metabolism -- live

Almost all life on Earth, e.g. our food and health, depend on metabolism in plants. To understand how these metabolic processes function, researchers are studying key mechanisms in the regulation of energy metabolism. A new method of in vivo biosensor technology has enabled them to monitor in real time what effects environmental changes have on the central metabolism of the model plant Arabidopsis...

An AI algorithm to help identify homeless youth at risk of substance abuse

While many programs and initiatives have been implemented to address the prevalence of substance abuse among homeless youth in the United States, they don't always include data-driven insights about environmental and psychological factors that could contribute to an individual's likelihood of developing a substance use disorder. Now, an artificial intelligence (AI) algorithm could help predict...

Study explores the association of malaria, HIV with anemia during pregnancy

Pregnant women from sub-Saharan Africa with malaria and human immunodeficiency virus (HIV) have a higher prevalence of anemia than pregnant women without infections, according to researchers. The findings may have implications for reducing the risk of death in pregnant women and preventing low birth weights and neurocognitive impairment in their children as a result of anemia.

Seeing a fluid behaving like a solid

Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a solid-like response to stress, a phenomenon called Discontinuous Shear Thickening (DST). This is when liquid abruptly thickens and becomes solid when disturbed. DST is being researched for engineering...

Source of pathogen that causes bitter rot disease

Fungal spores responsible for bitter rot disease, a common and devastating infection in fruit, do not encounter their host plants by chance. Turns out, they have a symbiotic association with the plant, often living inside its leaves. The new way of looking at the fungal pathogen, Colletotrichum fioriniae, as a leaf endophyte -- bacterial or fungal microorganisms that colonize healthy plant tissue...

Social connection is the strongest protective factor for depression

Researchers have identified a set of modifiable factors from a field of over 100 that could represent valuable targets for preventing depression in adults. The team named social connection as the strongest protective factor for depression, and suggested that reducing sedentary activities such as TV watching and daytime napping could also help lower the risk of depression.

Linking sight and movement

Researchers found that image-processing circuits in the primary visual cortex not only are more active when animals move freely, but that they receive signals from a movement-controlling region of the brain that is independent from the region that processes what the animal is looking at.

Scientists demonstrate how genetic variations cause eczema

New research delineates how two relatively common variations in a gene called KIF3A are responsible for an impaired skin barrier that allows increased water loss from the skin, promoting the development of atopic dermatitis, commonly known as eczema. This finding could lead to genetic tests that empower parents and physicians to take steps to potentially protect vulnerable infants from developing...
