June 17, 2017: A couple of days back, I was walking on the beach, and a question came to my mind: What happens to living beings that die in the ocean? Living beings who live in the ocean and die there, or other beings that die in the ocean (for example if a plane crashes in an ocean, or a ship sinks or a wave takes someone with it, etc). I did some research and found this:

If a living being dies on land and is not burnt or buried, then either scavenger eat the body, or it is decomposed, or it becomes a fossil. Similarly, when a living body dies in the ocean, it is either scavenged, decomposed or becomes a fossil.

At the ocean floor, dead bodies become food for deep-sea animals. First, there is a stage of mobile scavenging in which scavengers eat the body. Then there is an enrichment opportunist stage, in which small organisms live inside remains of the body, and finally, there is the sulpho philic stage, in which hydrogen sulfide emitting bacteria help feed chemotrophic organisms.

If the dead body is quickly covered by sediment and left undisturbed, it becomes a fossil. How fast a body becomes decomposed or scavenged depends on various factors: oxygen level, temperature, depth, light, speed of sinking, etc.

Some interesting words related to this topic are:

Detritivore is an organism that feeds on dead or decomposing organic matter. Taphonomy is the study of the processes that affect animal and plant remains as they become fossilized. A taphonomist is the person who does this study.

Chemotropism is the orientation of cells or organisms in relation to chemical stimuli.

This is all I have found. Please share your opinion on what you think, or if you have any additional relevant information.

Study Shows That Antibacterial in Toothpaste May Combat Severe Lung Diseases

Researchers have found that a common antibacterial substance found in toothpaste may combat life-threatening diseases such as cystic fibrosis (CF) when combined with a drug.

Researchers have found that a common antibacterial substance found in toothpaste may combat life-threatening diseases such as cystic fibrosis (CF) when combined with a drug.

The study, published in the journal Antimicrobial Agents and Chemotherapy, found that when triclosan — a substance that reduces or prevents bacteria from growing — is combined with an antibiotic called tobramycin, it kills the cells that protect the CF bacteria, known as Pseudomonas aeruginosa, by up to 99.9 per cent.

CF is a common genetic disease with one in every 2,500 to 3,500 people diagnosed with it at an early age. It results in a thick mucus in the lungs, which becomes a magnet for bacteria.

These bacteria are notoriously difficult to kill because they are protected by a slimy barrier known as a biofilm, which allows the disease to thrive even when treated with antibiotics, the researcher said.

“The problem that we’re really tackling is finding ways to kill these biofilms,” said lead author Chris Waters, Professor at the Michigan State University.

According to the researcher, there are many common biofilm-related infections that people get such as ear infections and swollen, painful gums caused by gingivitis.

But more serious, potentially fatal diseases join the ranks of CF including endocarditis, or inflammation of the heart, as well as infections from artificial hip and pacemaker implants, the researcher added.

For the study, the researchers grew 6,000 biofilms in petri dishes, added in tobramycin along with many different compounds, to see what worked better at killing the bacteria.

Twenty-five potential compounds were effective, but one stood out, the researcher said.

“It’s well known that triclosan, when used by itself, isn’t effective at killing Pseudomonas aeruginosa. But when I saw it listed as a possible compound to use with tobramycin, I was intrigued. We found triclosan was the one that worked every time,” said Alessandra Hunt from the Michigan State University. (IANS)
