Heavy rain on Mars reshaped the planet’s impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet’s surface as we see on Earth.

Extreme weather has greater impact on nature than assumed
An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Philosophical Transactions of the Royal Society B researchers of the Netherlands Institute of Ecology (NIOO-KNAW) launch a new approach to these 'extreme' studies.
Researchers make waves in the ultrasound world
A team of Ryerson researchers, led by Scott Tsai, have developed a new method to create the uniformly minuscule microbubbles most desirable for use in ultrasound imaging.
Study solves mystery of how plants use sunlight to tell time via cell protein signaling
Findings of a new study solve a key mystery about the chemistry of how plants tell time so they can flower and metabolize nutrients.
Varied increases in extreme rainfall with global warming
A new study by researchers from MIT and the Swiss Federal Institute of Technology in Zurich shows that the most extreme rain events in most regions of the world will increase in intensity by 3 to 15 percent, depending on region, for every degree Celsius that the planet warms.
NASA Aims to Create First-Ever Space-Based Sodium Lidar to Study Poorly Understood Mesosphere
A team of NASA scientists and engineers now believes it can leverage recent advances in a greenhouse-detecting instrument to build the world’s first space-based sodium lidar to study Earth’s poorly understood mesosphere.
Scientist Diego Janches and laser experts Mike Krainak and Tony Yu, all of whom work at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are leading a research-and-development effort to further advance the sodium lidar, which the group plans to deploy on the International Space Station if it succeeds in proving its flightworthiness.
NASA’s Center Innovation Fund and the Heliophysics Technology and Instrument Development for Science programs are now funding the instrument’s maturation. However, the concept traces its heritage in part to NASA’s past investments in promising lidar instruments, called Sounders, originally created to measure carbon dioxide and methane in Earth’s atmosphere.
