Ice Slurry

Ice slurry is an equal mix of ultra-small ice particles and a salt water liquid carrier. Originally, it was developed in the mid-1980s for industrial applications, particularly to replace the chilled-water cooling systems in building complexes.

Ice slurries contain ice particles that have a very high cooling capacity which is five to seven times the cooling capacity of chilled water. People suffering from cardiac arrests outside of the hospital have a lower recovery rate as their brain cells start dying rapidly 10 to 12 min after an arrest, because of the lack of blood flow to the brain. Beyond this time, the person cannot make a full recovery, even if the heart can be restarted, the person is brain dead.

Recovery rate can be improved if we are cooling the brain, using ice slurry. An ice slurry fills the lungs and if necessary, the area surrounding the carotid arteries. The blood passing through these is rapidly cooled. Chest compressions send the cooled blood to the brain. Ice slurry is injected in the body to induce rapid internal cooling.

Research shows that the ice slurry can cool the brain by 10.8 degree Fahrenheit within 10 minutes thus reducing or even stopping the damage done to the brain. Ice slurries have thus gained vital importance in the field of medicine.

Pykrete - "The Ice Concrete"

Pykrete, also known as Ice Concrete, is an unusually strong substance made from sawdust and water. It was invented by Max Perutz. It is named as pykrete, in honour of Geoffrey Pyke, a British scientist. It is made by mixing approximately 14% sawdust or wood pulp and 86% water by weight and then frozen.The resulting material is strong and non-brittle. It has some interesting properties over pure ice.

It has a slow melting rate. Vastly improved strength and toughness, which is closer to concrete. It can float on water. It is also resistant to flame. It has a crush resistance of greater than 21 megapascals. Even a 25 mm column could support the weight of a typical car. The wood pulp makes the pykrete stable at higher temperatures and imparts it so much strength that even if a .303 caliber bullet is fired at the pykrete, it will penetrate only 16cm.

The biggest use of pykrete was made in World War II, in the construction of a 2 Million Ton Aircraft carrier. The concept was to use reinforced ice to cheaply construct ships that would be virtually unsinkable and relatively resistant to submarine attacks. The project was named as "Project Habbakuk". Unfortunately the project was never put into action due to the lack of funds. Since WWII pykrete has remained a scientific curiosity, unexploited by research or construction of any significance. New concepts for pykrete however crop up occasionally among architects, engineers and futurists, usually regarding its potential for mammoth offshore construction or its improvement by applying super-strong materials such as synthetic composites or Kevlar.

LHC - The atom smasher

LHC stands for "Large Hadron Collider". It is the world’s most powerful particle accelerator. It is a 27-kilometer ring buried deep below the countryside on the outskirts of Geneva, Switzerland.

This huge project is being managed by CERN, the European Organization for Nuclear Research, one of the world’s largest and most respected centers for scientific research.

"LHC" is designed to produce head on collisions between two counter rotating beams of protons or heavy ions. These beams will be made to travel through a vacuum, comparable to outer space. A proton in a beam will make thousands and thousands of turns per second, thus generating about 800 million collisions per second.

The collisions can lead to extraordinary discoveries about the nature of the physical universe and can also shed some light on some of the science's most controversial topics the origins of mass, dark matter,hidden symmetries of the universe and new dimensions of space.

It is estimated that about 12-14 petabytes of data will be generated each year. Thousands of scientists around the world will collaborate, on the analysis of such huge amount of data, through a distributed computing network called the Grid, which will consist of tens of thousands of computers located around the world.

The first collision will take place on September 10, may 2008. There are rumors that the Cern's atom-smasher could create "mini black holes" that will grow exponentially and eat the planet from inside.

Digital Photo Frame

DPF (Digital photo frame) is a picture frame that displays digital photos. It can display JPEG pictures, multimedia content and text files. It can also play MP3 audio files. Sizes may range from 5 to 10 inches.

A digital photo frame consists of three main parts, the LCD-panel, the PCB and the outside frame. The panels can vary in size. The PCB includes the device's software.

DPF's today come with an internal memory of up to 1GB-2GB, allowing you to store more snaps. They also support USB ports for PC connectivity and for inserting pen drives. They also offer memory card slots, for SD cards, CMF, MS, MMC, XD, CompactFlash and Memory Sticks too.

Many new advanced DPF's support wireless (802.11) connections or Wi-Fi. With this they can transfer data to the onboard memory, they can load pictures over the Internet from RSS feeds or other photo sharing websites like Flickr.

Beware of low cost digital frames as they might contain a computer Trojan Horse, a virus, embedded in their firmware.

Google Chrome

Finally Google has launched the beta version of its new free web brower, Google Chrome. It is the first true Web 2.0 brower. Chrome is a very pure browser design because of its completely modular architecture,that gives it an edge over other browsers. It is a browser with sophiscated technology to make web, faster, safer and easier.

Earlier browers were designed to handle only text and graphics, but Chrome can handle video rich and other complex web programs.This browesr uses simplicity and some clever new features to bring web surfing into the 21st century.

Chrome eats more memory because of its each-tab-is-separate design. It opens a separate instance of the browser for each tab, a design that is used used to segregate tabs, and the sites on them, so that if one crashes the browser as a whole does not.

Chrome is only available for PCs, efforts are being made to make versions for Apple Macintosh users and for Linux devices.

MOSES

It is a $7bn government-funded scheme, to save the magnificent city Venice, the pride of all Italy.

Venice is a city on stilts. Built on 117 small islands in the middle of a lagoon, that flows into the Adriatic Sea. Venice has sunk around 23cm into the surrounding lagoon during the past 100 years and high waters are submerging the city's streets and piazzas with increasing frequency.

This huge responsibility of keeping Venice from drowning, is on the shoulders of the Consorzio Venezia Nuova (CVN), a private consortium of engineers and architects. The CVN's solution to this problem,is the Mo.S.E. (Modulo Sperimentale Elettromeccanico or Experimental Electromechanical Module) Project. It involves the construction of a set of 79 mobile floodgates. These steel barriers are up to five metres wide and 28 metres high.

These 300-ton gates are designed to lie flat on the seabed, to let normal tides in and out. They are inactive, filled with water and hidden from view. When a tide of one meter is forecast, air will be injected into these gates, pushing out the water and causing the gates to rise. As a result the gates will separate the lagoon from the Adriatic sea. As the tide drops, the gates will be refilled with water and return to rest on the seabed.

There were fears that closing the lagoon for long periods will cause it to stagnate, thus damaging marine life. To overcome such environmental challenges many new complementary projects were implemented by the CVN to defend the city.

Ice Cube

The Ice Cube is a $272 million project carried out by an international team of scientists, engineers and technicians, working under the harsh Antarctic conditions, at the South Pole. It is a gigantic scientific instrument--a telescope for detecting illusive particles called neutrinos that can travel millions of miles through space, passing right through the planets.

When the novel telescope is completed in the next several years, a cubic kilometer of ice at the “bottom of the world” will provide a new eye into the heavens and some of the most distant and violent events in the cosmos. The telescope, is an international effort involving more than 20 institutions.

It is an unusual telescope in many respects. It is buried a mile down in the Antarctic ice sheet, rather than situated at the surface. IceCube looks down, into the earth, rather than up into the sky. Finally, the "light" seen by this telescope is composed of individual fundamental particles called neutrinos.

IceCube will search for neutrinos from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars.

The Ice Cube telescope is a powerful tool to search for dark matter, and it could reveal new physical processes associated with the enigmatic origin of the highest energy particles in nature.

Knol

It is an online-publishing service, launched by Google. It allows users to write an authoritative article about a specific topic. The topics may range from scientific concepts, to medical information, from geographical and historical, to entertainment, from product information, to how-to-fix-it instructions.

They will provide all the easy-to-use tools for writing, editing, and so on, and will also provide free hosting of the content. The key idea behind the Knol project is to highlight authors. All the editorial responsibilities and control will rest with the authors. Here you can also collaborate with other authors and contribute. You also get an oppurtunity to make money by selecting the show ads option.

This service is likely to compete with online encyclopedia Wikipedia, whose articles tend to rank highly in Google search results. Knol is a potential competitor to Wikipedia.

The Moroccan foal

A mule is the hybrid of a horse and a donkey and should be sterile. Scientifically speaking a horse has 64 chromosomes and a donkey has 62, so a mule is left with 63, an uneven number which cannot divide into chromosome pairs. This should make a mule unable to reproduce. But in this case the 14-year-old mother mule gave birth to a male foal in a hamlet, deep in rural Morocco. The Moroccan foal(young horse or a pony) looks a bit like a baby donkey and a bit like a baby mule - but not exactly like either.

Thomas Beatie

The dramatic picture of a bearded, apparently pregnant, Beatie has sparked horror in tabloid and conservative circles and some are claiming it is a hoax. Thomas Beatie, 34, is a transgender man, born in Hawaii as Tracy Lagondino. She underwent a sex change, which involved regular injections of testosterone, and having his breasts surgically removed, but keeping his female reproductive organs and legally became a man. He stopped his twice-weekly hormone injections, allowed his periods to return, and tried for a baby. A first attempt, ended in a life-threatening ectopic pregnancy. Doctors have expressed concern, at the possible effect of testosterone, on the unborn child. He halted his bi-weekly testosterone, did not take any extra oestrogen, progesterone or fertility drugs to aid his pregnancy and after four months his menstrual cycle began again. Now, following anonymous sperm donation and home insemination,he is pregnant again and is due to give birth to a baby girl in July.
