This may seem like something out of a science fiction movie: researchers have designed micro-particles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can't breathe anymore.
It's one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.
The invention, developed by a team at Boston Children's Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.
The solution has already been successfully tested on animals under critical lung failure. When the doctors injected this liquid into the patient's veins, it restored oxygen in their blood to near-normal levels, granting them those precious additional minutes of life.
Particles of fat and oxygen
The particles are composed of oxygen gas pocketed in a layer of lipids, a natural molecule that usually stores energy or serves as a component to cell membranes. Lipids can be waxes, some vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, or—as in this case—fats.
These fatty oxygen particles are about two to four micrometers in size. They are suspended in a liquid solution that can be easily carried and used by paramedics, emergency crews and intensive care personnel. This seemingly magic elixir carries "three to four times the oxygen content of our own red blood cells."
- There are 62,000 miles of blood vessels in the human body – laid end to end they would circle the earth 2.5 times.
- The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft). The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin.
- Each kidney contains 1 million individual filters. They filter an average of around 1.3 litres (2.2 pints) of blood per minute and expel up to 1.4 litres (2.5 pints) a day of urine.
- The focusing muscles of the eyes move around 100,000 times a day. To give your leg muscles the same workout, you would need to walk 80km (50 miles) every day.
- Brain is capable of having more ideas than the number of atoms in the known universe!
- A single rye plant can spread up to 400 miles of roots underground.
- The evaporation from a large oak or beech tree is from 10-25 gallons in 24 hours.
- Plants cannot change their habitat.
- Petals are usually colourful, and they attract insects and birds that help with pollination.
- Onions contain a mild antibiotic that fights infections, soothes burns, tames bee stings and relieves the itch of athletes’ foot.
- Shark’s need to swim, or they will sink!
- All dogs are identical in anatomy - 321 bones and 42 permanent teeth
- An ostrich’s eye is bigger than it’s brain.
- A duck’s quack doesn’t echo, and no one knows why.
- Butterflies taste with their feet.
- A plastic cup can take 50 - 80 years to decompose. About 14 billion pounds of plastic is dumped in the world’s oceans every year.
Most of you will promptly say that monsoon is the rainy season. Monsoons in fact are some very strong winds. Thing to remember is that these winds,monsoon, always blow from cold to warm places.
In summers, when centre and north of India becomes very hot, winds(monsoon) from over the Indian Ocean blows towards this hot region. On their way these winds absorb a lot of water from the Indian ocean. So now imagine this wind carrying infinite number of tiny water balloons with it.
Soon this wind reaches the southern tip of India ( remember the ‘V’ of india, that’s the southern tip!) . Here they hit the mountains of India – Western ghats on the west and Eastern ghats on the east.
Now you know what happens when water balloons hit a hard surface? They burst into a splash of water! That is exactly what happens when the water laden wind hits the Indian mountains. The infinite tiny water balloons burst, releasing water and resulting in rains.
These monsoon winds don’t stop here and travel across a large part of India giving us our rainy seas
