We know what you ate: Detailed protein maps assess intestinal health

A new Weizmann Institute study identified all proteins in a stool sample – those from the microbiome, human body, and food – revealing secrets of the intestines and their impact on human disease. The method, dubbed IPHOMED, decodes microbiome activity by showing which proteins come from bacterial strains and amounts.

On the way to building better batteries

Weizmann researchers create new method to analyze dendrites in lithium-ion batteries, finding optimal composition for safe energy storage. The study reveals 'golden ratio' for electrolyte balance, extending battery life and reducing fire hazard.

Revealing underwater secrets with new technique

Researchers developed a new technique to estimate prey size and energy content from animal-borne camera footage, providing insights into predator-prey interactions and foraging strategies. This study on Humboldt, King and Tawaki/Fiordland penguins sheds light on the feeding behavior of marine wildlife.

Davis Instruments Vantage Pro2 Weather Station

Davis Instruments Vantage Pro2 Weather Station offers research-grade local weather data for networked stations, campuses, and community observatories.

Avoiding the double-edged sword of energy storage technology

The study reveals that battery production depends on over 35 materials and critical minerals, posing significant human health and environmental risks. Sustainable solutions like green energy systems, tailings backfilling, and circular economy strategies are proposed to mitigate these impacts.

Temperature, rainfall and tides speed glacier flow on a daily basis

A new study reveals that glacier speed varies on a daily basis due to changes in air temperature, rainfall, and tides. The research found acceleration events coinciding with high temperatures or heavy rainfall, highlighting the complex interactions between environmental factors and glacial dynamics.

A new approach to detecting Alzheimer’s disease

Researchers at Lancaster University have developed a new method to detect Alzheimer's disease by analyzing changes in brain oxygenation dynamics and neuronal function. The study found that individuals with Alzheimer's disease exhibit altered respiratory frequency, which may be an early indicator of the condition.

Could the contraceptive pill reduce risk of ovarian cancer?

Researchers found that women who had used the oral contraceptive pill had a lower risk of ovarian cancer, with a 39% reduced risk for those who had given birth to two or more children. The study also identified certain biomarkers and lifestyle factors associated with a lower risk of ovarian cancer, including lower body weight and short...

Speed of risk perception is connected to how information is arranged

A study by Tokyo Metropolitan University found that nurses have a faster response when presented with words showing high or low risk ailments, but individual directional biases vary. The researchers' findings may inform better ways to present clinical information, potentially leading to improved medical care and lives saved.
