The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
In cancer cells, major changes in gene expression increase glucose uptake to support their rapid growth. Unlike normal cells, which produce lactate only when oxygen is low, cancer cells convert much of the glucose to lactate even in the presence of adequate oxygen. This is known as the “Warburg Effect.”
During the final stage of freezing, an ice drop develops a pointy tip, which is not observed for most other liquids, and arises because water expands as it freezes. [10] Once the liquid is completely frozen, the sharp tip of the drop attracts water vapor in the air, much like a sharp metal lightning rod attracts electrical charges . [ 10 ]
A newly identified colon cancer gene may drive the disease by making the environment in the vicinity of tumors more hospitable to them, researchers say. Why does colon cancer grow so fast? Study ...
The findings raise hope for more effective treatments for pancreatic cancer, which has a poor survival rate. Shutdown of crucial gene helps world’s deadliest cancer grow rapidly – study Skip ...
The World Health Organization's cancer agency released a statement on Wednesday saying that 'very hot' beverages may be cancerous. The World Health Organization's cancer agency released a ...
Generally, it is believed that the cancer arises, or a pre-existing cancer is encouraged, during the process of repairing the trauma, rather than the cancer being caused directly by the trauma. [83] However, repeated injuries to the same tissues might promote excessive cell proliferation , which could then increase the odds of a cancerous mutation.
To reduce the risk of cervical cancer deaths, Siegel recommends getting the Pap test and the HPV vaccine, as well as the removal of any precancerous lesions found during screening. "For prostate ...
