Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»

Gene editing technology reveals molecular mechanisms governing diatom population density signals
The intricate dynamics of diatom blooms, influenced by a myriad of external factors and internal signals, continue to fascinate scientists. After recognizing the potential role of density perception and intracellular signaling in dictating these phen.....»»
New hydrogel can stretch to 15 times its original size
A team of molecular engineers at Tsinghua University, in China, has developed a new type of hydrogel that can stretch to 15 times its original size and then snap back to its original form. In their study, published in the journal Science, the group m.....»»
Novel role for metabolites in cellular metabolism discovered
Investigators led by Issam Ben-Sahra, Ph.D., associate professor of Biochemistry and Molecular Genetics, have discovered how cellular metabolism fluctuates in response to changes in levels of pyrimidines, metabolites used by cells to make DNA and RNA.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Study suggests starvation decimated gray whales off the Pacific Coast: Can the giants ever recover?
When large numbers of gray whales began washing up along North America's Pacific Coast nearly six years ago, marine scientists could only speculate on the reason: Was it disease? Ocean pollution? Increasing ship collisions?.....»»
Memories of mitosis: Molecular mechanism that detects defects during cell division could aid cancer treatment
Every day, our cells are hard at work multiplying. Cell division is a precise process, but sometimes this process is impaired and diseases like cancer occur. Mitosis is one of the most important phases in the cell cycle. During this phase, a cell's D.....»»
