Why tenants choose to move out in connection with renovation‎

One in three tenants who moved out of a municipal rental apartment in Gothenburg in connection with renovation said the renovation was a main reason for their decision, and many of them moved out even before construction began. A new study from Chalmers University of Technology shows that concerns about disruption, uncertainty and unclear information can be just as important as rent increases.

Team selected for NASA program to explore potential lunar cave‎

NASA has selected a Planetary Science Institute–led proposal to investigate whether a potentially large underground cave extends beyond the opening of a lunar pit. Such a cave may one day provide a safe haven for astronauts to escape the radiation and extreme temperature swings present at the lunar surface.

Changes to platinum surface chemistry boost solar hydrogen production in organic photocatalysts‎

Researchers from the LIMNO laboratory at EPFL have uncovered how different halides modify the surface chemistry of organic semiconductor nanoparticle photocatalysts. By controlling these phenomena, they have significantly improved the solar hydrogen production efficiency of these materials.

Researchers turn America's scattered local laws into a free searchable database covering all 50 states‎

America is a nation of local laws—millions of them. From noise ordinances and construction codes to rules about fishing licenses and roadside mango peddling, every town, city and county has its own set of regulations and unique way of doing things.

Marine biologists discover new plankton off Oregon coast‎

Nearly every morning when she was a doctoral student in the College of Arts and Sciences (CAS), Nicole Nakata, Ph.D. '23 (biology), would cross the street from the Oregon Institute of Marine Biology (OIMB) in Charleston, Ore., to the high-tide line of the Pacific Ocean. Her job was to catch microscopic brittle star plankton larvae from the incoming tidal current and bring them back to OIMB's labs to analyze under a microscope.

Mowing less, spraying smarter give pollinators a boost‎

Roadsides may not look like wildlife habitat, but a few simple changes to how they are maintained could turn them into much better places for pollinators. A new uOttawa-led study found that reducing mowing and herbicide use along rural roadsides led to a 45% jump in pollinator numbers and a 23% increase in the number of species found there.

Scientists discover first type I superconductor that breaks time-reversal symmetry‎

Superconductors are materials that conduct electricity with no resistance and expel magnetic fields when cooled to ultralow temperatures. And depending on their quantum structure, they can also showcase strange properties like magnetic levitation. But now things are getting a little weirder.

On complex political issues, most Americans take shortcuts to simplicity‎

A core assumption in any democracy is that citizens with access to information will make reasoned decisions on political candidates and policy issues. But a new study by UC Berkeley social scientists finds that Americans usually don't consider the full scope of difficult issues, instead basing their opinions on mental shortcuts that sidestep complexity.

American beech trees may carry genetic resistance to deadly leaf disease‎

A study led by scientists at the Holden Arboretum has found evidence that beech leaf disease (BLD) symptom development is genetically controlled, providing the first evidence that some American beech trees may have genetic resistance. This finding supports further investigation and development of breeding populations for BLD resistance. Nearly a third of beech trees near BLD's epicenter in northeastern Ohio, the majority of which were smaller trees, have died since the disease was discovered in 2012.

Plasma-activated water tests show concentration matters for effective bacterial disinfection‎

In a study published in npj Clean Water, researchers from EPFL investigated how Escherichia coli responds to different concentrations of plasma-activated water (PAW) under nutrient-rich conditions. The team combined conventional colony-forming unit (CFU) counting with nanomotion sensing, a technique that detects nanoscale oscillations produced by metabolically active bacteria.
