Destructive crop caterpillar harbors fungi that can degrade Styrofoam‎

A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as Styrofoam. In an article published in the journal BMC Microbiology, researchers from the Federal University of São Carlos (UFSCar) and São Paulo State University (UNESP) in Brazil presented the results of a study investigating the gut microbiota of Helicoverpa armigera and its role in degrading this petroleum-derived plastic.

NASA's new space telescope will tackle some of the universe's biggest mysteries‎

NASA is about to launch a space observatory that could help settle some of the biggest mysteries in modern astronomy. The Nancy Grace Roman Space Telescope will study how the universe began, what it is made of and how it has evolved over time.

Mars auroras reveal miniature version of Earth's magnetic engine‎

NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth–based auroras.

Spent coffee grounds reveal a route to biodiesel and other bio-based products‎

Coffee grounds that usually end up being thrown away can have a second life as a raw material for producing biofuels and other high-value-added products. A study by the Universitat Rovira i Virgili (URV) has evaluated how to extract oil from coffee grounds efficiently while preserving the rest of the plant material so that it can also be used in other processes.

New physics-based metric improves estimates of climate-driven cooling demand‎

New research led by atmospheric scientists at the University of Hawai'i (UH) at Mānoa found that the century-old yardstick used across many industries to estimate air-conditioning and refrigeration energy demand—called cooling degree days—is missing something fundamental.

Melts in your mouth, but not in your car: The ongoing scientific quest to create heat‑resistant chocolate‎

There are few pleasures greater than letting a piece of chocolate melt slowly on your tongue. Indeed, the proximity of chocolate's melting point to our own body temperature is one reason it is so widely appreciated.

First 3D nanoscale maps of human airway epithelium reveal hidden architecture of lung defense cells‎

Researchers at Queen Mary University of London and University of Cambridge in collaboration with colleagues at HHMI Janelia and NIH, have created some of the most detailed three-dimensional maps ever generated of human airway cells, revealing how the specialized cells that protect our lungs are built and organized.

Lithium ions sprint up to 10,000 times faster when their molecular cages briefly open‎

An international collaborative research group led by Professor Bong June Sung of the Department of Chemistry at Sogang University and Professor Shinji Saito of the Institute for Molecular Science (IMS), National Institutes of Natural Sciences (NINS), and the Graduate University for Advanced Studies, SOKENDAI, has elucidated, at the molecular level, how lithium ions move within organic ionic plastic crystals (OIPCs)—which are attracting attention as solid electrolytes for next-generation batteries.

Zebrafish rebuild damaged 'second brain' networks in nine days, offering clues for nerve repair‎

Why can zebrafish regenerate damaged gut nerves while humans largely cannot? Michigan State University researchers have developed a new research tool that allows them to remove gut neurons in zebrafish and watch them regenerate in real time, helping scientists investigate one of regenerative biology's biggest questions. The work is published in the journal Stem Cell Reports.
