Japan's small cities may face higher care burdens under the compact city policy
As populations decline and age across the developed world, compact city strategies, which oversee the consolidation of urban facilities and guide residents toward transit-served hubs, have become mainstream policies. Yet most evidence about their benefits comes from cities that a

Plasma and graphene combine to protect metal surfaces from corrosion
Plasma is an ionized gas, often referred to as the fourth state of matter. Plasmas, which are created artificially by applying energy to a gas, are found in the fluorescent tubes that illuminate kitchens. However, they have many other possible applications, such as the production
Research team cuts cost of building reconstituted cell-free systems by 95%
Research team cuts cost of building reconstituted cell-free systems by 95%
A research team led by Professor Joongoo Lee in the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed an automated, modular method for assembling reconstituted cell-free systems, which are test-tube systems that can produce

Is the Northern Territory a ‘mini Trump-style government’?
The CLP’s ‘tough on crime’, pro-development agenda brings sweeping changes, which advocates say cut the NT’s most vulnerable out of the conversationGet our breaking news email, free app or daily news podcastThe Northern Territory is out of sight – and often out of mind – for many
Human activity has driven retreat of Antarctica's fastest melting glacier
Human-driven climate change significantly intensified the retreat of one of the most important glaciers in Antarctica during the 20th century. The Pine Island Glacier, which drains a large part of the West Antarctic Ice Sheet into the Amundsen Sea, is one of the biggest contribut

Nanopore technology identifies proteins molecule by molecule
Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology called "nanopore detection," a team at the University

Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble

Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B
Deadly Venezuela earthquakes raise concern in tremor-prone California
Deadly Venezuela earthquakes raise concern in tremor-prone California
In the aftermath of back-to-back earthquakes in northern Venezuela, which by Friday had killed more than 500 people and left thousands injured, experts in resilience planning have emphasized the increasing importance of disaster preparedness in earthquake-prone California.
Hawaiian short-eared owl deaths in Hawaiʻi primarily caused by vehicle collisions
Trauma from vehicle collisions caused the majority of documented deaths for the Pueo (Hawaiian short-eared owl), according to a statewide study led by researchers at the University of Hawaiʻi at Mānoa. The findings represent the most extensive mortality assessment to date for thi
COVID-era renter protection law slashed Virginia evictions, research finds
COVID-era renter protection law slashed Virginia evictions, research finds
In 2020, Virginia received approximately $1 billion through a federal COVID-era emergency rental assistance program, which aimed to motivate landlords nationwide to postpone evictions of tenants who could no longer pay rent due to the pandemic. But in Virginia, lawmakers did not

Switching spin states in manganese ions with light opens new path for molecular memory
Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran
