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 / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Phys.org / Spider monkeys pool their knowledge to find the best fruit
When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...
Phys.org / Brewing possibilities: Using caffeine to edit gene expression
What if a cup of coffee could help treat cancer? Researchers at the Texas A&M Health Institute of Biosciences and Technology believe it's possible. By combining caffeine with the use of CRISPR—a gene-editing tool known ...
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 / 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 ...
