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...
Veterinarians urge pet owners to prepare for the arrival of rabbit hemorrhagic disease
An emerging virus threatens both wild and pet rabbits in the United States. The fatal virus—which causes an Ebola-like disease called rabbit hemorrhagic disease—already has been reported in the western and southwestern United States.
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.

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...
Pesticide mixtures a bigger problem than previously thought
New research led by The University of Queensland has provided the first comprehensive analysis of pesticide mixtures in creeks and rivers discharging to the Great Barrier Reef.
Ups and downs in COVID-19 data may be caused by data reporting practices
- ScienceDaily
- 20/7/14 19:27
As data accumulates on COVID-19 cases and deaths, researchers have observed patterns of peaks and valleys that repeat on a near-weekly basis. A new study reports that those oscillations arise from variations in testing practices and data reporting, rather than from societal practices around how people are infected or treated.
A new path for electron optics in solid-state systems
- ScienceDaily
- 20/7/14 19:27
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.
Autism researchers map brain circuitry of social preference
- ScienceDaily

A new study reveals how two key neural circuits dictate the choice between social approach and avoidance. The findings will enable researchers to evaluate social interventions in autism.
Evolution after Chicxulub asteroid impact: Rapid response of life to end-cretaceous mass
The impact event that formed the Chicxulub crater (Yucatán Peninsula, México) caused the extinction of 75% of species on Earth 66 million years ago, including non-avian dinosaurs. One place that did not experience much extinction was the deep, as organisms living in the abyss made it through the mass extinction event with just some changes to community structure.
Tale of the tape: Sticky bits make better batteries
Where things get sticky happens to be where interesting science happens in a Rice University lab working to improve battery technology.
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...
Could recently spotted dim point sources explain the galactic center excess (GCE)?
Over the past decade or so, a number of astrophysics studies have detected an excess of gamma-ray radiation at the center of our galaxy. Despite the many attempts to understand this unexpected surplus of radiation, now known as the galactic center excess (GCE), its source and the reasons why it exists remain unknown.
Keeping innocent people out of jail using the science of perception
- ScienceDaily
- 20/7/14 18:33
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.

Some potential issues and possible...
About 94% of wild bee and native plant species networks lost, study finds
Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, York University researchers found.
