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 / To reach net-zero, reverse current policy and protect the largest trees in the Amazon, say scientists
At the United Nations Climate Change Conference in 2015, countries around the world committed to striving towards net-zero greenhouse gas emissions by the middle of the 21st century. But achieving this goal is difficult, ...
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 / 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 / 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 / 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 / Scientists recover the oldest wooden tools from a site in Greece
Two artifacts found at a lake shore in Greece are the oldest wooden tools to be uncovered so far and date back 430,000 years.
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 / Collaboration of elementary particles: How teamwork among photon pairs overcomes quantum errors
Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks of nature.
Phys.org / A protein 'tape recorder' enables scientists to measure and decode cellular processes at scale and over time
Unraveling the mysteries of how biological organisms function begins with understanding the molecular interactions within and across large cell populations. A revolutionary new tool, developed at the University of Michigan, ...
Phys.org / Microgravity rewires microbial metabolism, limiting space-based manufacturing efficiency
Scientists at the U.S. Naval Research Laboratory (NRL) have completed a spaceflight biology investigation aboard the International Space Station (ISS) that reveals how microgravity fundamentally alters microbial metabolism, ...
