Phys.org / Fossils reveal sea cows have engineered Arabian Gulf's seagrass ecosystems for over 20 million years
Today, the Arabian Gulf is home to manatee-like marine mammals called dugongs that shape the seafloor as they graze on seagrasses. A newly described fossil site in Qatar reveals that ancient sea cows engineered aquatic ecosystems ...
Phys.org / Meet Damhán Alla—the newly christened, spider-like feature on Jupiter's moon Europa
Irish planetary scientists have christened a spider-like feature on Jupiter's icy moon Europa as "Damhán Alla," which translates to "spider" or "wall demon."
Phys.org / Black hole eats star: Student helps chart gamma-ray burst that lasted for days
A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar explosion. With a flood of data ...
Phys.org / A new reference brain could make the clonal raider ant a go-to model species for neuroscience
Every clonal raider ant lives a nearly identical life. Each new generation of these blind, queenless ants is born at the same time, eats the same things, lives in the same environment, and—as an asexually reproducing species—has ...
Phys.org / Reddit field experiment examines what distinguishes lurkers from power users
Online discussions are often dominated by a small group of active users, while the majority remain silent. This imbalance can distort perceptions of public opinion and fuel polarization.
Phys.org / Slow changes in radio scintillation can nudge pulsar timing by billionths of a second
For 10 months, a SETI Institute-led team watched pulsar PSR J0332+5434 (also called B0329+54) to study how its radio signal "twinkles" as it passes through gas between the star and Earth. The team used the Allen Telescope ...
Phys.org / Spending less can deliver more climate-friendly nutrition
Eating healthily can save money and also cause less greenhouse gas emissions than most people's current food choices, according to a new global study that examined food costs, nutrition, and climate impact around the world.
Phys.org / Using soccer balls to refine computational fluid dynamics research methods
If you're a soccer fan, you're familiar with this common sight: A penalty kick is in place, with a "wall" of defenders lined up in front of the goal, ready to leap to try to block the ball if it sails overhead.
Phys.org / Study suggests Earth's inner core may have onion-like layered structure
An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core.
Phys.org / ALICE solves mystery of light-nuclei survival
Observations of the formation of light-nuclei from high-energy collisions may help in the hunt for dark matter.
Phys.org / Lunar soil analyses reveal how space weathering shapes the moon's ultraviolet reflectance
Southwest Research Institute (SwRI) scientists are collaborating with researchers at UT San Antonio to study how space weathering can alter the lunar surface materials to help interpret regional and global far-ultraviolet ...
Phys.org / An old jeweler's trick could unlock next-generation nuclear clocks
In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this longstanding goal by bombarding ...
