Cosmic history can explain the properties of Mercury, Venus, Earth and Mars
Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. The rings are associated.....»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Earth underwent a massive, rapid melting period after the last global ice age, new study suggests
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet—other.....»»
Researcher: Beefing up Border Patrol is a bipartisan goal, but the agency has a troubled history
With U.S. voters across the political spectrum strongly concerned about border security, presidential candidates Kamala Harris and Donald Trump have been trying to one-up each other on who can reduce migration at the nation's southern border fastest.....»»

A new generation of space materials left Earth on November 5 as they head to the International Space Station (ISS) to undergo testing in the brutal conditions of low Earth orbit......»»
Kristallnacht"s legacy still haunts Hamburg, even as city rebuilds former synagogue burned in Nazi pogrom
Johanna Neumann was 8 when she witnessed a mob of local citizens and Nazis vandalizing the Bornplatz Synagogue in Hamburg. They were "shouting and throwing stones at the marvelous glass windows," as she later said in an oral history interview. Other.....»»

Scientists have figured out why Martian soil is so crusty
On November 26, 2018, NASA's Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) mission landed on Mars. This was a major milestone in Mars exploration since it was the first time a research station had been deplo.....»»
The mechanics of ovulation: Study explains how muscle-like fibers help eggs squeeze out from follicle
Eggs pop out of ovaries. But what propels them has been unknown. Now, researchers from the University of Connecticut explain in an article published in the September 18 issue of the Proceedings of the National Academy of Sciences that tiny, muscle-li.....»»
Moon waves goodbye to Hera
As ESA's Hera mission for planetary defense departed its homeworld, it looked back to Earth to show the moon orbiting around it. In this sequence of images the terrestrial disk gradually shrinks as the spacecraft recedes away from it, and the moon mo.....»»
A human topological insulator: Researchers use choreographed dance to explain quantum materials
Science can be difficult to explain to the public. In fact, any subfield of science can be difficult to explain to another scientist who studies in a different area. Explaining a theoretical science concept to high school students requires a new way.....»»
Study of Venus"s Haasttse-baad Tessera suggests formation by two large impacts
A trio of geologists and environmental scientists from Universidad Rey Juan Carlos, Lawrence Livermore National Laboratory, and the University of Minnesota has found evidence suggesting that the Haasttse-baad Tessera formation on Venus was likely for.....»»
Still kickin" since the "70s: NASA"s Voyager mission keeps exploring
NASA's Voyager mission launched in the 1970s. Today, it's making history as it conducts new science. But how are two spacecraft from the '70s not just surviving, but thriving farther out in space than any other spacecraft has been before?.....»»
A single atom can change the directional profile of the light emitted in scanning tunneling microscopes
Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM.....»»
Scientists identify chemical properties of superheavy elements moscovium and nihonium
An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz and the Helmholtz Institute Mainz, succeeded in determining the chemical properties of the artificially produced superheavy elements moscovium and n.....»»
Researchers spot black hole feeding at 40x its theoretical limit
Similar feeding events could explain the rapid growth of supermassive black holes. How did supermassive black holes end up at the center of every galaxy? A while back, it wasn't t.....»»
Final Venus flyby for NASA"s Parker Solar Probe queues closest sun pass
On Wednesday, Nov. 6, 2024, NASA's Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus's surface. The flyby will adjust Parker's trajectory into its final orbital configuration, bringin.....»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
The secrets of baseball"s magic mud: Study quantifies its properties to show it"s not simply a superstition
The unique properties of baseball's famed "magic" mud have never been scientifically quantified—until now. In a paper in Proceedings of the National Academy of Sciences, researchers at the University of Pennsylvania School of Engineering and Applie.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
