In Reddit posts about climate change, just 1 in 25 links are to scientific sources - versus mass media and social media sources - evidencing the lack of science-based debate

A recent study on Reddit climate change discussions found that only 1 in 25 links are from scientific sources, highlighting the lack of science-based debate on the platform. The study also highlighted the dominance of mass media and social media sources, which often spread misinformation.

The atmospheric memory that feeds billions of people: Newly discovered mechanism for monsoon rainfall

A new study reveals the atmosphere can store moisture over extended periods, creating a physical memory effect. This 'memory' allows monsoon systems to flip between two stable states, with severe consequences for regions relying on monsoon rainfall.

Childhood brain tumors develop early in highly specialized nerve cells

Researchers have identified where and when the most aggressive subgroups of childhood brain tumors develop, revealing that they arise from precursor cells of highly specialized nerve cells. The study suggests that genetic changes occur many years before clinical symptoms appear, paving the way for possible early detection methods.

Formaldehyde releasers found in common personal care products

A new study reveals that over half of Black and Latina women reported using personal care products with formaldehyde-releasing preservatives, highlighting critical safety gaps in product regulation. The study found that these chemicals are present in a wide range of products, including shampoo, lotions, and eyelash glue.

Only 0.001% of the deep seafloor visually observed in seventy years, revealing gaps and bias in ocean exploration and global biodiversity understanding

A groundbreaking study estimates that only a minuscule fraction of the deep seafloor has been imaged, with less than 0.001% of the ocean floor having visual records. This limited exploration is largely due to high costs and geographical bias in ocean exploration efforts.

Will you live an unprecedented life?

Today's children will endure more climate extremes than any previous generation due to continued greenhouse gas emissions. The study highlights the social injustice of climate change and its impacts, with the most vulnerable children facing almost all, or nearly all, unprecedented exposure to heatwaves in their lifetime.

A “roadmap” of the fruit fly brain

The study provides an overview of the fruit fly connectome, enabling scientists to intelligently design experiments to investigate individual neurons or circuits. Sex-specific differences were identified between male and female specimens, shedding light on behavioural differences such as egg-laying and mating.

Configuration design method of mega constellation for low earth orbit observation

Researchers propose a configuration design method for mega constellations in Low Earth Orbit (LEO) using basic and accompanying satellites. The method considers satellite imaging width, formation flying of subgroup satellites, and global uniform coverage by payloads to optimize constellation configuration. By solving nonlinear optimiza...

Remote regulation of molecular diffusion in extracellular space of Parkinson’s disease rat model by subthalamic nucleus deep brain stimulation

STN-DBS treatment modifies the extracellular space (ECS) by increasing hyaluronic acid content, EAAT2 expression, and reducing extracellular glutamate concentration. This study demonstrates that STN-DBS enhances ISF drainage by restoring AQP-4 expression while decreasing α-synuclein levels.

One-week breast cancer radiotherapy proven as safe and effective as standard three-week treatment in 4,000-patient study over 10 years

A 10-year study confirms a one-week course of post-surgery radiotherapy is just as safe and effective as the traditional three-week regimen for early-stage breast cancer patients. This shorter schedule provides similar cancer control without additional long-term side effects.

After global catastrophe, urban and near-urban farming could be sufficient to sustain mid-size cities

A new study suggests that urban agriculture alone can only feed about one fifth of a city's population, but combining it with near-urban farming can ensure food security for the entire city. Peas are found to be the best crop for maximizing protein and calories while minimizing land requirements in normal climate scenarios.
