New research looks at how the geometry of shells relates to the energy input required to actuate snap-through instability.

The burgeoning field of optoelectronic devices is driving the development of new alkali metal-based chalcogenides with qualities that have to be robustly investigated.

Physically fit primary school pupils feel better and can concentrate better. They are more likely to make it to higher-level secondary grammar schools than children with less sporting ability.

The analysis of astrophysical plasmas is vital in the quest to learn about some of the Universe’s most powerful and mysterious objects and events such as stellar coronae and winds, cataclysmic variables, X-ray binaries containing neutron stars and blac…

Researchers have constructed a photovoltaic cell that harvests energy from the environment during the day and night, making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperature…

Clinical awareness of connection between alcohol and dementia is paramount to providing the best patient care management.

Scientists have gained new insights into how the eye of Drosophila processes motion patterns that are generated by self-motion through space. They have discovered that direction-selective cells can distinguish six types of global motion patterns.

Life on Earth runs in 24-hour cycles. From tiny bacteria to human beings, organisms adapt to alterations of day and night. External factors, such as changes in light and temperature, are needed to entrain the clock. Many metabolic processes are control…

Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than e…

Many cancers exhibit high levels of the reverse transcriptase enzyme. Single-agent lamivudine, a reverse transcriptase inhibitor, stopped disease progression in over 25% of patients with fourth-line refractory metastatic colorectal cancer. These result…

Biomedical engineers believe they have discovered the physical mechanism that causes high doses of antibiotics to promote the spread of antibiotic resistance between bacteria. The culprit, they say, is an overabundance of ‘jumping genes,’ called transp…

New research on postmenopausal women identifies associations between commonly eaten foods and the diversity and composition of oral bacteria.

On November 8, 2020, NASA’s Juno spacecraft flew through an intense beam of electrons traveling from Ganymede, Jupiter’s largest moon, to its auroral footprint on the gas giant. Scientists used data from Juno’s payload to study the particle population …

Like diseases affecting humans, parasites can wage a deadly evolutionary ‘arms race’ against their hosts. But can hosts and parasites upgrade their weapons at the same rate?

Scientists have developed a pollen-based ‘paper’ that, after being printed on, can be ‘erased’ and reused multiple times without any damage to the paper.

Honey might be a sweet solution for developing environmentally friendly components for neuromorphic computers, systems designed to mimic the neurons and synapses found in the human brain. Hailed by some as the future of computing, neuromorphic systems …

A new study has compiled a global database of climate-induced forest die-off events, from 1970-2018, across 675 locations. After analyzing the climate conditions at each location during each event, researchers found a common ‘hotter-drought fingerprint…

Although clinical labs have known for almost a century that a oddly shaped nucleus resembling pince-nez glasses in blood cells could indicate leukemia, the cause of this anomaly remained unknown. Scientists have now discovered that loss of nuclear Lami…

A new study has found that squid will camouflage against coral reef and other substrate as a way of avoiding predation.

A new method of obtaining ancient genomic data without damaging source material has been developed, creating new opportunities for museum and archaeological collections worldwide.
