Frontline safety concerns mount among property managers, new survey shows

Safety and security challenges are creating unprecedented strain for frontline property management professionals, according to a new bilingual survey conducted by Portland State University's Center for Real Estate. Initiated after industry partners raised alarms about changing workplace conditions, the study offers insight into the daily risks experienced by property management staff at multifamily and commercial properties.

CubeSat instrument extends solar storm warnings 10x

The sun is the reason life exists on our small, blue planet. It provides solar radiation that warms the planet and ignites intricate biochemical processes like photosynthesis, producing oxygen for life to breathe. However, while the sun is known for giving life, it can also take it away with solar flares, geomagnetic storms and solar radiation storms, collectively referred to as space weather.

Satellite data reveal ESG scores track public image more than actual forest loss

Environmental sustainability researchers at NUS found that widely used environmental, social and governance (ESG) ratings often fail to reflect companies' actual exposure to deforestation, highlighting the need to integrate satellite-based environmental data into sustainable investing frameworks.

How individual cells 'surf' chemical waves to form a collective

Researchers have developed an innovative imaging technique to visualize the transition of single cells into multicellular organisms in new detail.

Biophysical model suggests how cells optimize information gathering without using too much energy

In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical Review Letters, describes a model for how a sensor or cell might maximize information collection from its surroundings while controlling the overall energy cost, resulting in an optimized system.

Local experience shapes how coastal communities understand and respond to climate change

While people across the globe are experiencing various impacts of climate change, governments and communicators often use top-to-bottom, uniform communication strategies to inform people about climate change.

Fertilizer study reveals where the world can boost food production and cut pollution

Global consumption of fertilizer has doubled since 1980, but some regions that have historically overused fertilizer, including China and parts of Europe, have taken steps to reduce use. Those are some of the findings of a new global dataset from the University of Minnesota's Institute on the Environment.

New research calls for more consistent, child-centered policing to build trust and protect children

New research co-led by the University of Bedfordshire and the University of Lancashire has highlighted the need for more consistent child-centered and safeguarding-led approaches across policing, with children and young people's experiences varying depending on where they live, whom they encounter, the reason for these encounters and how well systems support frontline practice.

Examining Americans' complicated relationship with science

A new study finds that while most Americans are interested in science and believe it benefits society, the public's relationship with science is more complicated than those positive views suggest.

Planting trees in the wrong places is not a climate solution

A recent United Nations report has stated that the world will likely overshoot the 1.5°C target set out in the 2015 Paris Agreement by 2030.

Marine bacteria team up to break down one of the ocean's toughest carbon-storing molecules

Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form their protective outer layers. The fucoidan molecule is very difficult for microbes to break down because its chemical structure may include dozens of different linkages and branching patterns that vary from one algal species to another.

Scientists create 'super ice' that is ten times stronger and far harder to shatter

Ice is cheap, abundant and surprisingly strong. But it has one major weakness: Cracks can race through it, causing it to shatter without warning. Now, scientists have developed a new material that could overcome that problem. Called BioPykrete, the reinforced ice is about 10 times stronger than ordinary ice and can absorb roughly 70 times more energy before breaking.

Advanced X-ray crystallography determines structure of macromolecule at unprecedented resolution

Proteins are high-performance molecular machines that carry out nearly every biochemical function inside living cells. To understand how they achieve this, scientists often examine their detailed atomic structure, which holds important clues to their activity. The more precision they achieve, the deeper the insight they may gain into the chemical principles that underlie protein structure and, ultimately, function.

Ancient DNA traces medieval migration from Sweden to Finland

A new study led by the University of Turku provides new insights into the population history of Finland during the Late Iron Age and the Middle Ages. The researchers analyzed the genomes of people who lived in southwestern Finland and Häme between the 11th and 13th centuries to investigate how the population changed over the course of the Middle Ages and how people were connected to other regions around the Baltic Sea.

Europe's e‑waste is a valuable resource—let's not throw it away

Throwing something away that is urgently needed, expensive and difficult to source sounds crazy. Yet of the 60 metals contained in old electronic devices such as phones, screens and washing machines, only a few are recycled. That includes precious metals such as gold and silver and other metals such as aluminum and copper. The rest are effectively single-use metals, used once and then lost during collection or through incineration.

Our new research shows humans have maligned bandicoots for decades, making them more vulnerable to extinction

Have you ever found your lawn riddled with holes or heard a little sneeze from your backyard bushes? Those are signs you might have a resident bandicoot. Bandicoots are nocturnal, rabbit-sized marsupials known for their pointy snouts, thin tails and large hind feet. Due to these features, they were originally misnamed after a type of rat from India, the pandi-kokku, or "pig-rat" (Bandicota sp.).

Laser altimeter BELA ready to explore Mercury's surface

Launched on Oct. 20, 2018, the joint ESA/JAXA BepiColombo mission has traveled for almost eight years, using a carefully planned but eventful sequence of planetary flybys and solar-electric propulsion to gradually approach its destination, Mercury. The mission is now entering the final stage of its journey to the smallest and innermost planet of our solar system.

A 5,000-year-old royal mystery: Digital clues point to Meretneith as Egypt's female king

More than 5,000 years ago, a royal woman named Meretneith (also written as Merneith) lived in ancient Egypt. She was possibly the daughter of Djer, the third king of the First Dynasty, a period when the first kings ruled over a unified Egypt.

To crack the job market, internships can be just as key for young people as the degree

College students are facing one of the most precarious labor markets in years. A recent New York Federal Reserve study pointed to a sharp increase in unemployment among recent college graduates compared with other workers, with explanations ranging from artificial intelligence job displacement to a broader slowdown in hiring.

Children trust what they hear over what they see, study finds

New research from our Department of Psychology has revealed that children are far more likely than adults to judge a person's emotions by what they hear rather than what they see.
