Slow wi-fi is a source of irritation that nearly everyone experiences. Wireless devices in the home consume ever more data, and it’s only growing, and congesting the wi-fi network. Researchers at Eindhoven University of Technology have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light. This was the subject for which TU/e researcher Joanne Oh received her PhD degree with the ‘cum laude’ distinction last week.

Expertise is clearly beneficial in the workplace, yet highly trained workers in some occupations could actually be at risk for making errors when interrupted, indicates a new study by two Michigan State University psychology researchers.

Using a powerful telescope, scientists view spiral pattern of gaseous emissions around LL Pegasi and its companion star.

Grasses are better able to withstand drought or high temperatures than many other plants in large part due to changes in their pores, called stomata. Stanford scientists have discovered how grasses produce these altered pores, which could someday lead to crops that can better survive climate change.

New research from the University of Warwick generates fresh insight into how a raindrop or spilt coffee splashes.

Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.  

The first global, long-term satellite study of airborne ammonia gas has revealed “hotspots” of the pollutant over four of the world’s most productive agricultural regions. The results of the study, conducted using data from NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite, could inform the development of strategies to control pollution from ammonia and ammonia byproducts in Earth’s agricultural areas.

A University of Maryland-led team discovered steadily increasing ammonia concentrations from 2002 to 2016 over agricultural centers in the United States, Europe, China and India. Increased concentrations of atmospheric ammonia are linked to poor air and water quality.  

Measures such as river restoration and tree planting aim to restore processes that have been affected by human activities like farming, land management and house-building. Natural flood management is an area of increasing interest for policy makers, but its implementation can present a complex balancing act between the needs of different groups, including the public, farmers and land owners. Mixed messages about their effectiveness and the scale needed to implement natural flood management measures successfully add to the uncertainty surrounding their benefits. Now a team of experts, led by Dr Simon Dadson of the School of Geography and the Environment at the University of Oxford, has compiled evidence on natural flood management to inform policy decision-making and show where there are still crucial gaps in knowledge. The article shines a light on the scientific evidence available from a variety of sources, ranging from field data to model projections and expert opinion.

Plants possess molecular mechanisms that prevent them from blooming in winter. Once the cold of win-ter has passed, they are deactivated. However, if it is still too cold in spring, plants adapt their blooming behavior accordingly. Scientists from the Technical University of Munich (TUM) have discovered genetic changes for this adaptive behavior. In light of the temperature changes resulting from climate change, this may come in useful for securing the production of food in the future.

Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70 percent, in a new study conclusion that bodes well for airline economics and Earth’s environment.

The findings are the result of a cooperative international research program led by NASA and involving agencies from Germany and Canada, and are detailed in a study published in the journal Nature.
