Phys.org / How starfish control tube feet without a central nervous system or brain
Starfish, also known as sea stars, are equipped with an almost alien-like anatomy. Despite lacking a brain, blood, and central nervous system, these odd creatures still have locomotive abilities. The structure of their many ...
Phys.org / First carbon-enhanced metal-poor stars discovered in Milky Way's companion
Using the Baryons Oscillation Spectroscopic Survey (BOSS) spectrograph, astronomers have discovered five new carbon-enhanced metal-poor stars in the Large Magellanic Cloud (LMC). This is the first time such stars have been ...
Phys.org / How gut bacteria control immune responses
Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led by researchers at Helmholtz Munich, with participation from Ludwig Maximilians University (LMU), ...
Phys.org / Exceptionally well-preserved ant in Goethe's amber examined
Even some 200 years after his death, Johann Wolfgang von Goethe's scientific curiosity continues to yield new insights. This has now been demonstrated by biologists at Friedrich Schiller University Jena while closely examining ...
Phys.org / Toothbrush-activated powder whitens, repairs and protects teeth
Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the process. So, researchers ...
Phys.org / Tapping into risk in America's drinking water
When you turn on the tap, you can typically expect clean, safe water to flow out. But behind that simple action lies a complex system of pipes, pumps, governance, and financials that, for millions of Americans, is at risk ...
Phys.org / Shrubs curb carbon emissions in China's largest desert, decades-long experiment shows
An experiment in western China over the past four decades shows that it is possible to tame the expansion of desert lands with greenery, and, in the process, pull excess carbon dioxide out of the sky.
Phys.org / Mighty microscopic fibers are the key to cell division and life itself
Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle. The spindle extends its many fibers from the chromosomes ...
Phys.org / Swimming in a shared medium makes particles synchronize without touching
Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a steady electric field. The result was curious, but lonely. Now, Northwestern University engineers have ...
Phys.org / Sloshing liquefied natural gas in cargo tanks causes higher impact forces than expected
What happens if liquefied natural gas (LNG) hits the wall of the cargo tanks in a ship? New research from the team of physicist Devaraj van der Meer from the University of Twente, published in the Proceedings of the National ...
Phys.org / Sea levels are rising—but in Greenland, they will fall
Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper published in Nature Communications. "The Greenland coastline is going to experience quite ...
Phys.org / Hibernating hamsters maintain muscle cells by suppressing muscle regeneration, study shows
Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation during the hibernation period, a research team led by Hiroshima University has shown. This insight ...
