A new study has revealed how humans become infected with cholera. The infection is linked to RNA in the human body which triggers a rise in temperature. This rise in temperature signals to the contaminating bacterium to release a toxin.
Astronomers watching features on Saturn’s moon Titan were astonished to see a “land” feature simply disappear on photos from the Cassini spacecraft. This large feature, a peninsula on the Saturnian hydrocarbon “sea,” seems to have disappeared.
A new study suggests the origins of water on Earth may lie far outside our solar system, in interstellar space, and took place long before the formation of the sun. If so, the same chain of events that led to life on Earth could happen elsewhere.
Scientists at the University of Colorado Anschutz Medical Campus are to examine the genes from people with a form of epilepsy called Dravet Syndrome and who have been treated with medical marijuana. The aim is to see if medical marijuana helps.
Australian scientists have discovered that the mantis shrimp has an amazing ability: the shrimps can detect a variety of cancers inside the human body. The researchers hope to harness this to make a special camera.
Lengthy spells in intensive care units can alter the gut microflora, according to a new study. When a patient spends a long time in ICU the gut seems to undergo near-complete ecologic collapse. This has major health consequences.
The search for microorganisms to use in biofuel generation has led to the human lower intestine. A new study demonstrates how such microorganisms could be effective candidates for organic fuel production.
The world's preeminent theoretical physicist has explicitly acknowledged for the first time that he is an atheist, explaining that "science offers a more convincing explanation" of the origins of the universe than 'God.'
Humans have lived with deadly epidemics since they formed the first communities. Researchers study ancient scourges, such as the bubonic plague, in order to understand how the body responds to infections. Such insights can inform about modern infections.
The American Meteor Society is reporting four large fireballs over various parts of the eastern United States. Witnesses first spotted the fireballs on Tuesday but many also saw the strange sights into Wednesday.
