The true power of the solar wind
The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought. These findings are important for the ESA mission BepiColombo, Europe's first Mercury mission. (2018-06-12)

Solar cells combining silicon with perovskite have achieved record efficiency of 25.2 percent
In Neuchâtel (Switzerland), researchers from EPFL and CSEM have combined silicon- and perovskite-based solar cells. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent. (2018-06-11)

How to suck carbon dioxide from the sky for fuels and more
Someday, the gasoline you buy might come from carbon dioxide pulled out of the sky rather than from oil pumped out of the ground. By removing emitted carbon dioxide from the atmosphere and turning it into fresh fuels, engineers at a Canadian firm have demonstrated a scalable and cost-effective way to make deep cuts in the carbon footprint of transportation with minimal disruption to existing vehicles. Their work appears June 7 in the journal Joule. (2018-06-07)

Thank the moon for Earth's lengthening day
A new study that reconstructs the deep history of our planet's relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around its axis. (2018-06-04)

In nearly zero energy buildings special attention must be paid to window design
For the last two years TTÜ Nearly Zero Energy Buildings Research Group led by Professor Hendrik Voll (currently holding the position of TTÜ Vice-Rector for Academic Affairs), with support from personal research funding (PUT, i.e. funding for high level research projects), has been seeking solutions for daylight and solar shading for nearly zero energy buildings in cold climates.

UMD-led study shows how Earth slows the solar wind to a gentle breeze
A University of Maryland-led study describes the first observations of the process of electron heating in Earth's bow shock. The researchers found that when the electrons in the solar wind encounter the bow shock, they momentarily accelerate to such a high speed that the electron stream becomes unstable and breaks down. This breakdown process robs the electrons of their high speed and converts the energy to heat. (2018-05-31)

Can we get 100 percent of our energy from renewable sources?
In a review paper last year in Renewable and Sustainable Energy Reviews, Benjamin Heard and colleagues presented their case against 100 percent renewable electricity systems. They doubted the feasibility of many of the recent scenarios for high shares of renewable energy. Now scientists have hit back with their response to the points raised by Heard and colleagues. They demonstrate that there are no roadblocks on the way to a 100 percent renewable future. (2018-05-17)

Researchers propose how REM and non-REM sleep may work together to help us solve problems
Sleep is known to be important for creative thinking, but exactly how it helps and what role each sleep stage -- REM and non-REM -- plays remains unclear. A team of researchers have now developed a hypothesis, outlined in an Opinion published May 15 in the journal Trends in Cognitive Sciences, to explain how the interleaving of REM and non-REM sleep might facilitate creative problem solving in different but complementary ways.

Reconnection tames the turbulent magnetic fields around Earth
Wherever magnetic fields occur in the cosmos, their field lines tend to cross and reconnect, spitting out charged particles. To date, space scientists have studied these short circuits in the near-Earth environment, but only in rather calm regions of the magnetosphere. Now scientists led by Tai Phan at UC Berkeley have seen how turbulent magnetic fields reconnect in the much more violent magnetosheath. While normal reconnection generates ion jets, turbulent reconnection creates electron jets. (2018-05-09)

New research reveals how energy dissipates outside Earth's magnetic field
A new research paper in Nature provides the first evidence that magnetic reconnection--a process that dissipates magnetic energy and accelerates charged particles in Earth's magnetic field--also occurs at very small spatial scales in the turbulent magnetosheath. The results suggest that small-scale magnetic reconnection may play a role in heating the solar corona and the solar wind, as well as turbulent magnetic systems elsewhere in space. (2018-05-09)
