Researchers have achieved making different electronic components transparent. However, batteries were not one of them. So far, the bulk of research dedicated to battery technology is to make them store more energy and to keep it stored longer.
But Yi Cui, a materials science professor at Stanford University, led researchers in creating a fully transparent battery. “If you can’t make the battery transparent, you can’t make the gadget transparent,” says Cui. This development is another step closer in creating fully-transparent devices. It could lead to design of portable gadgets.
Although some parts of the battery are relatively easy to create using transparent materials, the electrodes particularly are not. They had to create a mesh with a pattern that’s smaller than the naked eye. To hold the mesh together, a clear polymer called PDMS was used.
Currently, this method of fabrication can create a battery that can hold half a charge of a non-transparent battery of the same size.
Cui is working to improve on this with further research.
Two years ago, scientists at the Fraunhofer Institute for Interfacial Engineering and Biotechnology in Germany had the idea of a skin factory. They wanted to be able to produce low-cost skin that can be used for clinical testing.
That idea is now a reality.
In a sterile and climate-controlled factory, computers control the robots, blades and lasers that produce the skin. In it, pink solutions that are constantly monitored for infection are squeezed through small pipes and come out as human skin. These are then cut into discs the size of a penny. The factory produces 5,000 of these discs per month. The objective is to mass-produce human tissue that can be used for treating injuries and other medical conditions.
According to director Heike Walles, it is even possible to efficiently produce bigger tissues such as bladders and even human organs but only through facilities like this. Indeed, she and several others have successfully produced engineered tissues suitable for transplantation on humans. However, that process is still very expensive and requires too much work. She believes a simpler and cheaper method can only be achieved using a fully-automated manufacturing factory.
Based on European Union regulations, several stages of successful animal testing are required before clinical testing on humans can be allowed. Currently, It is still a long way from human transplantation.
Low cerebrospinal fluid headaches can be debilitating. Commonly, a lumbar puncture results in an internal fluid leak in the spine. The brain sags as the fluid leaks out. For many patients suffering from low CSF headaches, pain can be disabling. Currently available therapies are not totally effective. The only relief is from lying down. This means that it interferes with or prevents their daily activities.
Botox offers new hope to these patients and a case study has been presented by Mayo Clinic at the American Academy of Neurology meeting in Hawaii.
“We had been using Botox for several years for treatment of migraine and had been successful in many patients. And because we really didn’t have anything else to offer her, we gave her the Botox. To everybody’s surprise she made a remarkable improvement,” says Dr. Cutrer, a neurologist at Mayo Clinic in Rochester, Minn. A visual pain monitor confirms the pain’s reduction from eight to three in a 10-point scale.
The effect lasts for about three months before pain returns and would then need a new dose. Although it may not be a cure, patients can now live more normal lives.
Ja Rule, the American rapper, singer, and actor, was reported receiving another 2 years in prison after pleading guilty to a tax evasion case.
Ja Rule, whose real name is Jeffrey Atkins, was sentenced in New Jersey federal court Monday, July 18, 2011 to a 28-month imprisonment for not paying his taxes amounting to more than $1 million. According to the prosecutors, Ja Rule did not pay taxes from years 2004 to 2008, costing the U.S. government more than $1.1 million.
“Taxpayers do not have the luxury of deciding whether to comply with laws,” U.S. Judge Patty Shwartz said on Monday in delivering the sentence.
This is the second case for the singer. Last year, Ja Rule was also convicted with a weapon possession when authorities discovered a semi-automatic handgun in July of 2007 hidden in his car after the police instructed him to pull over.
Rihanna’s LOUD Tour concert touched down Dallas’ American Airlines Stadium last Friday with her nerve breaking performance. Her thousands of fans filled the stadium and together they danced and sang with her as she performed “Only Girl (In The World),” “S&M,” “Shut Up And Drive” and “Disturbia”.
As she was about to end her hit song “California King Bed”, her pyrotechnics went out of control and sparks began to rain down on her. She exited the stage immediately while the audience were also asked to evacuate the place. This has lead to end her concert earlier than expected. She wasn’t able to perform “Umbrella,” “What’s My Name,” “Rude Boy” and “SOS” which were among the most popular songs.
Some of her fans asked for a refund for their tickets but were only promised to witness Rihanna performing the concert again from scratch in her next available schedule. She also promised to her fans that her other concert dates would be on schedule.
There were no detailed reasons on what went wrong to the her stage that night. Maybe it was just a mere electrical problem.
One of her fans watching the concert was able to take a video of the fire and uploaded it in Youtube. The video clearly showed fire on top with its sparks falling on the floor.
Does the list of worst economies in the world interests you? You might not want to consider living in these countries perhaps.
Last Tuesday, July 5, 2011, Forbes Magazine, released its list of 2011 Top 10 World’s Worst Economies with Madagascar leading the list.
As mentioned in Forbes.com, all 177 countries were ranked according to the average statistics for their Gross Domestic Product (GDP) growth and inflation for the past 3 years. GDP is s often considered an indicator of a country’s standard of living while inflation refers to the rise in the general level of prices of goods and services in an economy over a period of time.
Among them, it was Madagascar who went on top with a $448 per-capita gross domestic product which was three times between 1970 and 2009, as revealed by United Nation (UN). Economic mismanagement were one of the reasons why the country got on top of the list.
In case you don’t know where Madagascar is, it is located in the Indian Ocean off the southeastern coast of Africa.
Second to Madagascar is Armenia, the former Soviet Union Republic which has an inflation rate currently running at 7%, with a per-capita GDP of $3,000.
Below are the complete Top 10 Worst Economies as released by Forbes Magazine:
