Innovation is widespread in rural areas, not just cities

A new study at Penn State found that incremental improvements made by businesses outside of their firm are crucial for economic growth and employment. The 'latent' innovation index assigns scores to counties based on opportunities for improvement, showing that rural areas can foster innovation too.

HIV patients lose smallpox immunity despite childhood vaccine, AIDS drugs

A study published in the Journal of Infectious Diseases found that HIV-positive women who received a childhood smallpox vaccine still retained some immunity to the virus, despite receiving antiretroviral therapy. This limited response suggests that while HIV treatment can boost overall immune function, it may not restore specific memor...

Math test score gap between white and non-white students in Brazil due to complex factors

A Brazilian study analyzed math test scores for 9th-grade students, revealing that performance gaps between different racial groups can largely be attributed to socio-economic factors. However, for high-scoring students, structural factors like discrimination and stereotypes play a greater role in perpetuating the gap.

Climate signals detected in global weather

A group of scientists has conducted a new analysis that concludes the 'weather-is-not-climate' paradigm is no longer applicable. They found that daily weather data can reveal long-term warming trends, provided global spatial patterns are considered.

Climate change and deforestation could decimate Madagascar's rainforest habitat by 2070

A study in Nature Climate Change predicts Madagascar's entire eastern rainforest habitat will be eliminated by 2070 unless strict protections are implemented. The research identifies priority areas for protection, highlighting the critical role of ruffed lemurs as seed dispersers and their sensitivity to habitat degradation.

Craft-beer boom linked to record-number of US states growing hops

A study by Penn State researchers found that the growth of craft breweries in the US is linked to an unprecedented expansion of hop production across 29 states. The number of breweries more than quadrupled from 992 to over 4,000 between 2007 and 2017, resulting in a five-fold increase in hop farms and acreage.

Rhythmicity of cluster headache

A study found that cluster headache attacks exhibit a dynamic circadian and seasonal pattern, with changes in the attack timing throughout the disease course. Patients with more lifetime bouts showed a less variable pattern compared to those without circadian rhythmicity.

Snake-like proteins can wrangle DNA

Researchers at Rice University have discovered a novel mechanism by which snake-like proteins, known as coiled coils, interact with DNA to form loops that regulate genetic messages. These loops are formed through a braiding process, where the coiled coils writhe and twist around each other, bringing together sites on DNA.

Bystander CPR less likely for people living in Hispanic neighborhoods

A study by Penn Medicine found that residents of Hispanic neighborhoods are less likely to receive CPR from a bystander and have a lower chance of survival following cardiac arrest. The study analyzed over 27,000 cardiac arrest events and showed a significant disparity in CPR delivery rates between Hispanic and non-Hispanic neighborhoods.

Plants can improve your work life

A study published in the American Society for Horticultural Science journal HortTechnology found that simply gazing at an indoor plant can reduce psychological stress in office workers. The researchers discovered that even passive involvement with plants, such as having a plant on their desk, contributed to significant anxiety reduction.

A close look at thin ice

Researchers have discovered a novel mechanism of ice growth in two dimensions, shedding light on the atomic structure of low-dimensional water. This finding may lead to the development of new materials for efficient ice removal, particularly for wind turbines and other applications.

All global sustainability is local

A new study assesses country and regional progress towards 17 UN Sustainable Development Goals (SDGs), revealing disparities between developed and developing regions. The study suggests that sustainability progress is dynamic and may involve tradeoffs, highlighting the need for a holistic approach to address these challenges.
