Imaging of sequential potential distribution changes in electrodes during charge/discharge

NIMS has succeeded for the first time in visualizing sequential changes in electrical potential distribution across a composite electrode during charge/discharge reactions in all-solid-state lithium ion batteries. This distribution was previously measureable only before and after the occurrence of charge/discharge reactions. Microscopic understanding of charge/discharge reaction mechanisms in...

The geographies of COVID-19

A pneumonia of unknown cause was first reported to the World Health Organization (WHO) on 31 December 2019 in China's Hubei Province.

29,000 years of Aboriginal history

The known timeline of the Aboriginal occupation of South Australia's Riverland region has been vastly extended by new research led by Flinders University in collaboration with the River Murray and Mallee Aboriginal Corporation (RMMAC).

Huge Atlas statue to guard Sicily's Temple of Zeus once more

Eight-metre statue built in 5th century BC had been buried among ancient ruinsA colossal statue of Atlas, buried for centuries among ancient ruins, will soon take its rightful place among the ancient Greek temples of Agrigento on Sicily.The city’s archaeological park announced that the artwork, one of the most celebrated sculptures on the island, will be raised upright in front of the Temple of...

Coalition backs 'cloud-brightening' trial on Great Barrier Reef to tackle global heating

Greens deride $4.7m funding for technologies that may shade corals and make clouds more reflective as ‘Band-Aid solutions’ A government-backed research program to make the Great Barrier Reef more resilient to global heating will spend $4.7m this financial year developing technologies that could shade corals and make clouds more reflective during marine heatwaves.The announcement confirms the...

A new path for electron optics in solid-state systems

In combined theoretical and experimental work, physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to engineering quantum-optical phenomena in a variety of materials and devices.

Underused part of the electromagnetic spectrum gets optics boost from metamaterial

Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless communications (6G/7G), security systems, biomedicine, and even art history. A new device for controlling T-rays using a specially designed 'metasurface' with properties not found in nature could begin to...

Covid-19 outbreaks up to 20 times more likely in large care homes, study finds

Exclusive: likelihood of UK homes being infected triples with every additional 20 bedsCoronavirus – latest updatesSee all our coronavirus coverageCoronavirus outbreaks are up to 20 times more likely in large care homes, according to a major study seen by the Guardian, prompting calls to divide them into “bubbles” before any second wave hits.In research that will increase scrutiny of private...

Keeping innocent people out of jail using the science of perception

People wrongfully accused of a crime often wait years -- if ever -- to be exonerated. Many of these wrongfully accused cases stem from unreliable eyewitness testimony. Now, scientists have identified a new way of presenting a lineup to an eyewitness that could improve the likelihood that the correct suspect is identified and reduce the number of innocent people sentenced to jail.
