Harvesting hot electrons without tricks can increase the efficiency of solar modules

This is a construction for the ultrafast spectroscopy used in the study. Credit: Maxim Pchenitchnikov, University of Groningen The efficiency of solar collectors is hampered by a "Goldilocks" problem: the light must have just the right amount of energy to be transformed into a voltage. Too little energy and the photons (light energy packets) pass through the panel. Too much …

The farthest explored object is renamed after a Nazi controversy

Composite image of the binary Kuiper Belt Object 2014 MU69 from New Horizons Spacecraft Data NASA NASA scientists from the New Horizons mission have renamed the farthest object Object that was ever explored for political controversy over its original name. Kuiper Belt Object 2014 MU69 was the name of Ultima Thule, a medieval term meaning a place beyond the borders …

California's Methane Super Emitter | Ars Technica

Methane is a much stronger greenhouse gas than carbon dioxide and binds much more heat. Point source methane emitters are typically small – typically less than 10 meters in diameter – but they emit clouds of highly concentrated methane. So, if we want to reduce the amount of methane we throw into the air (which we should of course do, …

We have identified a serious new health risk for manned spaceflight

We still find out what the possible effects of prolonged space stays on the human body may be. Now a new health threat has been identified that could jeopardize life on long journeys through the cosmos. The problem lies in the internal jugular vein (IJV), a large blood vessel that runs down the brain from the neck. A study of …

B & luru scientists shed some light on the 142-year-old solar puzzle

An international team of scientists, including two astrophysicists from Bengaluru, uncovered a 142-year-old mystery of the sun on Friday, opening a new window to investigate one of the sun's greatest mysteries. [19659002] The team of researchers from the Indian Institute of Astrophysics found out how sunspots – small plasma jets, of which about one million are on the Sun at …

Observe the evolution of a galaxy, from the Big Bang to today

To learn how galaxies change over time, scientists have created the most complex simulation of a galaxy called TNG50. The data from this simulation was used to create the above video, which shows the evolution of a massive galaxy from the beginning of the Universe to the present day. In the main window of the video denser gas is shown …

Research shows a new state of aggregation: a Cooper metal pair

Tiny holes punched in a high-temperature superconductive material showed that copper pairs, electron duos that facilitate superconductivity, and metals can conduct electricity. Picture credits: Valles Lab / Brown University For years, physicists have assumed that Cooper pairs, the pairs of electrons that allow superconductors to conduct current without resistance, are two-trick ponies. The pairs either slide freely and create a …
