Study finds Chinese plant biodiversity at risk due to human activity: Narrow-ranged losers, widespread winners

A study published in PNAS found that humans are driving the loss of biodiversity among narrow-ranged plant species in China, while widespread species are thriving. The research revealed that human impact factors lead to a negative correlation with narrow-ranged species and a positive correlation with widespread species.

Study: US takes 'low road' to growth with adverse impact on wellbeing, future prosperity

A new study published in the Cambridge Journal of Economics finds that countries taking the 'low road' to growth, like the US, experience adverse effects on wellbeing and future prosperity. In contrast, Scandinavian countries that take the 'high road' by investing in social reproduction see positive effects on human welfare.

There is no 'I' in team -- or is there?

A study published in the Journal of Occupational and Organizational Psychology found that individual psychological ownership boosts personal engagement and creativity, but decreases collective effort. Conversely, collective ownership enhances team engagement, but not necessarily individual performance.

Differentiating amino acids

Researchers from the University of Freiburg and US universities have developed a method to differentiate between individual amino acids in short peptides. They used an aerolysin nanopore to measure the ion current through the pore, enabling the sensitive measurement of peptide size and structure.

Social determinants of health are linked to gun homicide rates

A new study published in PLOS Medicine found that social determinants of health, such as income inequality and trust in institutions, are associated with higher gun homicide rates in the US. The study also showed that levels of social mobility and poverty are linked to neighborhood gun homicide rates.

And then there was light

Phytochromes can sense light intensity, duration, color, and day length by measuring the proportions of their inactive and active forms. Researchers have overcome a major hurdle to defining the transition between these states, allowing for atomic-resolution molecular movies of the process.

Applying physics principle yields grim prediction on hurricane destruction in an era

A physicist has developed a new model predicting the increased destructive power of hurricanes as water temperatures rise. The model is based on a physics principle and suggests that the destructive power of Atlantic hurricanes off Africa could reach three times their current level if water temperatures increase by 2 degrees Celsius.

Poor sight causes people to overstep the mark

Researchers at Anglia Ruskin University found that people with impaired vision lifted their lead foot higher but less quickly over obstacles, increasing their risk of falls. This pronounced gait also led to increased anxiety and decreased stability, highlighting the need for better vision correction and care.

High-def mapping of moisture in the soil

A new approach developed by University of Delaware researchers uses machine learning to predict soil moisture conditions in smaller areas with greater detail than standard models. This improves regional and global analysis while providing more accurate predictions even without existing data.

Suction cups that don't fall off

Researchers at the University of Cambridge have discovered how aquatic larvae of net-winged midges create super-strong suction organs, enabling them to move around on rocks in turbulent water. This study aims to inspire the development of bio-inspired suction cups with improved industrial applications.

'Locally grown' broccoli looks, tastes better to consumers

Consumers rated locally grown New York broccoli as better-looking and tasting than a California variety, even though it didn't look more appealing. The study suggests that labeling products as local can improve their perceived value and quality, regardless of actual differences in taste or appearance.
