For the first time, researchers have shown how cancer cells reprogram themselves to produce lactic acid and to tolerate the acidic environment that exists around tumors. The finding could lead to a whole new direction for ...
A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers at Ruhr-Universität Bochum (RUB). They used an opsin—a protein that occurs in the brain and eyes—from zebrafish ...
Argonne-driven technology is part of a broad initiative to answer fundamental questions about the birth of matter in the universe and the building blocks that hold it all together.
How do predators know to avoid brightly-colored toxic prey? A collaboration of researchers has put social information theory to the test in a reliable real-world system to find the answer—by copying what others do, or do ...

In the movie "A Fish Called Wanda," the villain Otto effortlessly gobbles up all the occupants of Ken`s fish tank. Reality, however, is more daunting. At least one unfortunate fan who re-enacted this scene was hospitalized ...
The Mid-infrared lasers (MIR) with high peak power and high repetition rate operating in the range of 2.7~3 μm have important application in laser surgery and optical parametric oscillator (OPO).
Bite marks, in the form of traces left on bones by the teeth of scavengers or predators, are not uncommon in the fossil record. These marks are sometimes impressively large. What they show is that carnivores of the past, ...
Germany is a hotspot for dragonflies and damselflies (Odonata) species in Europe, owing to the range of habitats and climates that it provides. While many recent and mostly small-scale studies suggest long-term declines of ...
Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.
