Biodiverse 'keystone food spaces' can help meet UN’s ‘Zero Hunger’ goal
Small farms and home gardens where landholders raise multiple species of culturally important crops can have a significant impact when it comes to meeting the United Nations’ goal to end global hunger and malnutrition, according to an international team of researchers.
Ultrahigh piezoelectric performance demonstrated in ceramic materials
The ability of piezoelectric materials to convert mechanical energy into electrical energy and vice versa makes them useful for various applications from robotics to communication to sensors.
Florida Keys offers foray into marine research for spring breakers
For several Penn State students taking a course on marine biogeochemistry, the coastal waters of the Florida Keys became an extension of their laboratory.
Decoding the leaf: scientists search for features to ID modern, fossil leaves
Machine learning programs that can classify leaves and place them in biological families may unlock new clues about the evolution of plant life, but only if scientists understand what the computers are seeing.
Upcycling plastic waste into graphite provides possible alternative to landfills
Upcycling plastic waste into graphite, used in electric vehicles and renewable energy storage, could positively contribute to the global economy, preserving resources, saving energy and reducing carbon dioxide emissions, according to Penn State researchers.
National 2D materials research center wins NSF funding
A national research center that brings together university, industry and government partners to develop atom-thin 2D coatings with wide-ranging industrial applications is expanding thanks to a grant from the National Science Foundation (NSF).
Printing circuits on irregular surfaces with pulses of light
Printable electronics could cause a proliferation of smart, connected devices, from household appliances that can communicate with each other to medical diagnostic sensors that can be placed on the body to forgo invasive procedures.
Finding new types of 2D material defects could enable better electronics
Two-dimensional materials are essential for developing new ultra-compact electronic devices, but producing defect-free 2D materials is a challenge.
Historic fire regimes lay groundwork for future forest management in western US
Fires in semi-arid forests in the western United States tended to burn periodically and at low severity until the policy of fire suppression put an end to these low-intensity events and created the conditions for the destructive fires seen today.
Algorithm helps probe connections between stream chemistry and environment
Machine learning techniques may help scientists better understand the intricate chemistry of streams and monitor broader environmental conditions, according to a team of researchers.
