You Can Make Diamonds Out Of Tequila!

Tequila may be just another drink to those out in the town, but to a team of scientists in Mexico their country’s native alcohol turned out to be a gem; a diamond, to be precise. Javier Morales, Luis Apátiga and Victor Castaño at the National Autonomous University of Mexico made the alchemist-worthy discovery while experimenting turning various organic solutions, such as acetone and ethanol, into diamonds. The scientists noted that 80-proof tequila (40 percent alcohol) had the ideal proportion of ethanol to water to create diamond films. In order to make the diamonds, they evaporated the tequila into a vapor, and then heated the vapor above 1400 degrees Fahrenheit before depositing it on silicon or stainless steel trays. The resulting diamond films were between 100 to 400 nm in diameter and free of impurities.

Hard and heat resistant, the diamond films could have several commercial applications, such as for cutting tools and optical electronic devices. At the moment, the team is looking into creating diamonds with impurities for potential use as a new kind of semiconductor. The scientists have bigger plans in sight, too: They intend to turn their work into an industrial-scale venture by 2011 and hope to find a tequila distiller to provide them with the supplies.

Phobias Might Be Memories Passed Down From Ancestors In Your DNA

Memories may be passed down through generations in DNA in a process that may be the underlying cause of phobias.

Memories can be passed down to later generations through genetic switches that allow offspring to inherit the experience of their ancestors, according to new research that may explain how phobias can develop.

Scientists have long assumed that memories and learned experiences built up during a lifetime must be passed on by teaching later generations or through personal experience.

However, new research has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA.

Researchers at the Emory University School of Medicine, in Atlanta, found that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations.

The results may help to explain why people suffer from seemingly irrational phobias – it may be based on the inherited experiences of their ancestors.

So a fear of spiders may in fact be an inherited defence mechanism laid down in a families genes by an ancestors’ frightening encounter with an arachnid.

Dr Brian Dias, from the department of psychiatry at Emory University, said: “We have begun to explore an underappreciated influence on adult behaviour – ancestral experience before conception.

“From a translational perspective, our results allow us to appreciate how the experiences of a parent, before even conceiving offspring, markedly influence both structure and function in the nervous system of subsequent generations.

“Such a phenomenon may contribute to the etiology and potential intergenerational transmission of risk for neuropsychiatric disorders such as phobias, anxiety and post-traumatic stress disorder.”

Making Electricity From Urine

Scientists have developed a way to convert urine in to a renewable energy source. But as Sally Magnusson, author of Life of Pee and presenter of Radio 4’s Secret Science of Pee, writes in this viewpoint feature, there is some way to go before the idea is embraced more widely.

A growing number of scientists have cottoned on to the fact that urine is a source of vital enzymes for medicine, precious minerals like fast-depleting phosphorus, and chemical compounds like urea, which are crucial to the manufacture of fertilisers, plastics and cosmetics and can also be used to make electricity.

The question is, can urine help us? And if so, can we see it not as a useless, embarrassing waste product, but as a substance that could drive the next stage of the green revolution?

I started out mildly intrigued by the range of uses urine had in centuries gone by – it was used in the manufacture of gunpowder, alum, dyes, paint and stained glass, to clean Roman togas, and heal wounds.

I wrestled with the revulsion that arises when we move from historical curiosity to envisaging personal application, but I ended up convinced there is an urgent role for urine again in the 21st Century, based on its unique scientific properties.

Urea, an important constituent of urine, is the key to many modern applications.

At Heriot-Watt University in Edinburgh, the Youtricity research team has developed a urine-powered system to generate electricity.

The carbamide power system runs on urea fuel cells sourced from human urine.

Dr Shanwen Tao, who invented the technology, said urea fuel cells were similar to hydrogen fuel cells, but used urea instead.

His colleague, Dr Robert Goodfellow said it had been a “huge” breakthrough in the search for renewable energy, but the system was being further developed.

66-Year-Old Man Discovers He’s A Woman!

A 66-year-old who lived his whole life as a man was given a surprising diagnosis after visiting the doctor in Hong Kong with a swollen abdomen — he was a woman.

Doctors realised the patient was female after they found the swelling came from a large cyst on an ovary, the Hong Kong Medical Journal reported.

The condition was the result of two rare genetic disorders.

The subject had Turner syndrome, which affects girls and women and results from a problem with the chromosomes, with characteristics including infertility and short stature.

But he also had congenital adrenal hyperplasia, increasing male hormones and making the patient, who had a beard and a “micropenis”, appear like a man.

“Were it not due to the huge ovarian cyst, his intriguing medical condition might never have been exposed,” seven doctors from two of the city’s hospitals wrote in the study published Monday.
