Surprising lake bigger than West Virginia inside the Greenland ice

Unlikely liquid water may hold clues to the effects of Global Warming

An ice core segment with water taken from the underground aquifer discovered in Greenland.

A vast aquifer lake lies trapped under southeastern Greenland. This discovery may help the scientific community to find reasons for the climate´s changing. The fact that there exists an aquifer 27,000 square miles under the Greenland region is a matter of scientific interest.

Lora Koening of NASA´s Goddard Space Flight Center said it is a magnificent discovery, because even thought water percolates down the surface when the ice melts, the water did not refreeze. Koening and a group of colleges went to Greenland to take core samples, and to prove if there exists life in Greenland´s aquifer.

The fact that melt water can remain in liquid form, provides information about how long it takes the water to get to the sea, and can determine how much and how fast the sea level will rise, which is of vital importance to the communities who live on the coasts.

Computers 1,000 times faster? Quick-change materials break silicon speed limit for computers




Faster, smaller, greener computers, with the processing power of over 1000 current computers. This technology can me made possible with new Phase Changing Materials!

The current silicon based microchips would be replaced with 'Phase-change materials' (PCMs). PCMs are capable of switching between different electrical states. One state is a crystalline conductor while the other a glassy insulator. It does this in under a Billionth of a second through small electrical shocks!

The difference between silicon based chips and PCMs is where logical operations and memory is located. In silicon based chips memory and operations are located separately while in the PCM chips they are located in the same spot. This means that Dynamic Random Access Memory can eventually be removed!

The Moving stones of Death Valley



   
    The moving stone's of Death Valley,CA


        Everyone knows that rocks can not move by themselves, yet there is one mystery, that has had scientists puzzled for decades. At Death Valley's national park, there lies a dried lake, also known as the Racetrack Playa. It has been said that many heavy boulders, some weighing up to 300 kg, have been found with long trails behind them, cutting a furrow in the sediment, as if they had moved. No one has actually seen the stones move, yet they have been said to be moving around a lot. 

       Their discovery was first made in the 1940's, and ever since then, many geologists have thought up many theories as to how or why the would have moved. Many of them have been proved wrong, and only recently have they been ably to get an idea of what might be causing this. Scientists believe that ice is the cause to this famous mystery.

    They have been able to gather evidence, using GPS devices and cameras. There is a thin layer of ice in which develops on the dirt, in which causes the rocks to move, yet the process is so slow, it would be hard for the human eye to capture it. This is why it still seems so hard to believe.

Fukushima Radiation: Our days of eating fish are over?







Following Japan’s devastating 2011 earthquake and tsunami, fear spread about risks of leaked radiation from the Fukushima nuclear power plant for the planet and the potential impacts on our complex marine food web.

It’s the largest single contribution of radiation to the marine environment ever observed. With 300 tons of contaminated water pouring into the sea every day, Japan’s government acknowledged the urgency of the situation.

It took 3 years from the time of the incident (2011) for the radiation plume to reach the West Coast, which is this year. Recent testing of migratory fish, including samples collected from Pacific blue fin tuna caught off the California coast, assessed radiation levels and potential effects on marine food webs far away from Japan, although they are below the level of being harmful for humans.

Any amount of leaked radiation is harmful to the planet and the health of all species, including humans. That doesn't mean it’s unsafe to eat all fish caught on the Pacific West Coast, but we should keep in mind that there are always long-term health risks.

Next, German Scientists have calculated the dispersion of radiation in the Pacific Ocean. Check the counter of the days in the top right:

Scientists Remotely Activate Genetic Target To Slow Aging Process

A team of researchers led by David Walker of UCLA have discovered the a gene that slows down the process of ageing. The AMPK enzyme found in all eukaryotic organisms assists in regulating the energy levels of cells and has been found to increase ATP production through fatty acid metabolism and increased glucose uptake. Through experiments with AMPK in fruit flies they have seen outstanding results. It is estimated that if it were to be used on humans, our life expectancy would increase from 80 years to 104; about 30% more. Our lives wouldn’t just be longer, but our life quality would be improved as well by being healthier for longer.

This revolutionary method of stopping ageing can prevent many diseases like: cancer, stroke, cardiovascular diseases and even diabetes. This may take many years, but scientist believe a healthier and slower ageing process is possible. The gene works effectively as it clears away cellular waste from your brain. If some dead cells are kept inside, it can lead to many diseases. The problem is that this is not very stable because a lot of AMPK can cause other problems to rise in humans. Research is ongoing but Dr Walker and his team are confident that this breakthrough could be brought to the patients in the next few years.

New fish species found in France!


"French ichthyologists led by Dr Philippe Keith of the National Museum of Natural History in Paris have described a new species of pike from the Charente to the Adour drainages of France." Sergio Prostak, 30 August 2014.

There has always been Pike species all over Europe. However, when scientists were exploring the species, they found out through morphological and molecular analysis that there was a new specie of such animal. There was the Northern pike and the Cisalpine pike which both are very common in French lakes. Then, they realized there was an unknown specie and they decided to call it Aquitanian pike because they found it in Aquitaine.

Cancer Patients Have New Hope After Israeli Scientist Research



Scientists in Israel, working as part of a 16 year study trying to find a cure for cancer, have had a significant breakthrough. Professor Avivi, of Haifa University has found that both the blind mole rat and the naked mole rat secrete a a substance that seems to destroy cancer cells in mammals. Experts believe that they can find a way to harvest this substance, and it is quite possible that it can be safe to take and can possibly wipe out cancer for humans too. 

The group of scientists tested both regular rats and these special mole rats and found that while the other rats developed tumors, the mole rats were able to secrete some sort of hormone or substance that destroyed the cancer, without causing any other harm to its body. A study published in the BMC Biology Journal concluded: “Exploring the molecular mechanisms may hold the key for understanding the nature of resistance to cancer and identify new strategies for treating humans.” 

The scientists believe that if they can find what genetic material/mutation caused this cancer resistance in the mole rats, they could possibly work with and modify human's genetic codes and successfully create a life saving treatment for many people.

Human Trials for Ebola Vaccine



The deadly Ebola virus has killed over 1500 people in West Africa, prompting the intervention from medical facilities to create a cure, or at least a way to treat the virus and give people hope. The WHO (World Health Organization) predicted that in the next 6 months, 20,000 more people could be infected.

A vaccine, with a focus on prevention rather than cure of the disease has been developed and has responded "extremely well" in primate studies but has yet to be tested in humans. This week, trials are beginning, and 140 patients will be tested, though none will be infected with the virus.

Why wasn't there a vaccine or cure for the disease before? Because Ebola has existed for 40 years, but before this outbreak it had been so rare that it hadn't been a priority to find a solution to it. All being well with the trial, Ebola could soon be the latest in a long line of dangerous viruses that we as humans have managed to win the battle with and control.

Bubble Powered Speed Machine


A current submarine can only go as fast as 83 km/h, however the Harbin Institute of Technology says that they want to raise that by two orders of magnitude, making it even faster than jet planes. They state that this supersonic submarine can go from Shanghai to San Francisco in 100 minutes! The method they would use is called "Supercavitation". This occurs when small bubbles produced by the motion of a solid object join, creating one huge bubble that is longer than the solid object itself. This makes the solid be surrounded by gas, instead of water, which allows it to travel at speeds even greater. The mantis shrimp does this to hunt prey and we use it to enable propeller blades to go faster. The issue is to make an object get so fast that this can occur and maintain that speed. Harbin Researchers Say that they have developed a liquid membrane that when showered on the front of the submarine, would slash drag and enable it to get to the needed speed. There are still some technical issues they need to solve in order to achieve this but this research suggests that a 6000 km/h submarine may soon be on the market.

Three Parents!?

10 years ago, the mother of Alana Saarinen had been unsuccessfully trying to have a baby. Doctors thought this was caused because of faulty mitochondria. So they removed the cytoplasm (with the mitochondria) of one of her eggs, and replaced it with a donor’s. This part that was replaced, however, not only produces energy for the cells, but also contains a genome with DNA. This procedure, known as mitochondrial replacing, not only gave birth to Alana Saarinen, but also gave her 3 different genes. Thats amazing! you might say. However, this procedure can have its downsides. Other babies that had transferred mitochondria haven't been as lucky. Some have mental disabilities, and in some cases, can cause miscarriages. Its still debated whether this type of birth should be allowed, since they also carry many risks. At least Alana was able to live a good and prosperous life.

Music Benefits Your Brain


Music Benefits Your Brain:

HD687700violin1.jpg


Studies in the University of Liverpool, show that when you practice musical training you can increase your blood flow to the left side of the brain. This can be seen with just 30 minutes of musical training. Learning a new language or learning to play an instrument use the same areas in the brain. They both increase the use of the left hemisphere of the brain. If you play an instrument or just listen to music you are actually working you’re working the left hemisphere of your brain either way. The findings were presented at the British Psychological Society Annual conference.
