Whether it was Rubik's Cubes, Sudoku or riddles, Nicole Beisel loved puzzles as a kid. Not much has changed. But these days the University of Florida doctoral student works with a lot more pieces and the stakes are higher. Much higher. Think Mars.

The new technology has the potential to replace the traditional “best before” date on food and drinks alike with a definitive indication that it’s time to chuck that roast or pour out that milk.

Former Tropical Cyclone Iris continues to linger in the Southwestern Pacific Ocean off the coast of Queensland, Australia. NASA-NOAA's Suomi NPP satellite passed over the remnants of Iris on April 10.

Cheetahs in the Serengeti National Park adopt different Two male cheetahs eat a killstrategies while eating to deal with threats from to​​​​​​​p predators such as lions or hyenas. A new study in Springer’s journal Behavioral Ecology and Sociobiology shows that male cheetahs and single females eat their prey as quickly as possible. Mothers with cubs, on the other hand, watch out for possible threats while their young are eating in order to give them enough time to eat their fill. The research was led by Anne Hilborn of Virginia Tech’s College of Natural Resources and Environment in the US.

Teams of scientists from the Ruhr-Universität Bochum (RUB) and the University of Warwick were able to observe the smallest details of hydrogen production with the synthetic mineral pentlandite. This makes it possible to develop strategies for the design of robust and cost-effective catalysts for hydrogen production. The working groups of Prof Dr Wolfgang Schuhmann and Dr Ulf-Peter Apfel from the RUB and the team headed by Prof Dr Patrick R. Unwin from the University of Warwick report in the journal Angewandte Chemie of 9 March 2018.

Participating in yoga and mindfulness activities at school helps third-graders exhibiting anxiety improve their well-being and emotional health, according to a new Tulane University study published in the journal Psychology Research and Behavior Management. 

University of Saskatchewan researcher Lindsay Goodwin has developed a new way to measure the impact of solar activity on the ionosphere as indicated by northern lights and geomagnetic storms. The ionosphere is the upper part of the atmosphere.

The agriculture industry is in a tough spot; it’s simultaneously tasked with feeding a growing population and minimizing its environmental footprint. For corn breeders, that means improving nitrogen-use efficiency and crowding tolerance, all while maximizing yield. The first step, according to a new study from the University of Illinois, is understanding the genetic yield potential of current hybrids.

This one simple mathematical trick can accurately predict the shape and melting effects of ponds on Arctic sea ice, according to new research by UChicago scientists.

New research is shedding light on how mechanically placed sand on San Diego County beaches moves and its potential impacts. The study, published in the journal Coastal Engineering, could help planners develop beach nourishment projects that will reach their intended goals without causing unintended problems. North San Diego County for instance is planning a 50-year, $160 million series of beach nourishments intended to combat flooding and erosion, and provide recreational space for tourists.
