Stem cells can be used to grow new teeth!! exciting news!!!!

Scientists from Japan recently published a paper that details how they successfully grew new teeth from the stem cells of mice.

According to MedicalXPress the research paper describing their successful growth and transplantation of the new teeth was published in the open access journal PLoS One.
  
Takashi Tsuji from Tokyo University of Science and his colleagues removed two different stem cells from the molar teeth of mice to build these teeth. They transported these cells to a laboratory where they could grow. To influence how the teeth grew in relation to size and shape, the cells were put inside of a mold to grow. 
  
When the cells developed into full tooth units, the researchers then placed them into the jaws of one-month-old mice. The transplanted choppers attached themselves to the jaw bones and tissues on an average of about 40 days.
  
They also saw that nerve fibers had begun growing in the engineered teeth.
  
Even better, the mice that were given the stem cell teeth had no problems chewing and eating like they normally would.
  
Tsuji hopes that this development will eventually lead to growing human organs from stem cells. Scientists cannot currently make full organs outside of a human body.
  
Tsuji maintains that the right stem cells must be used for building and repairing parts of the human body. Scientists think that in the future we will be able to make stem cell teeth for people. That way we can replace the teeth we lose in bar fights video game accidents.
  
The best part about this whole development is that people who are interested in the regeneration of teeth in mice using stems cells can read the complete research paper online.
  
After all, what good is a scientific development if people can’t read about it because of outdated pay walls?

Drinking Too Much Water Could Be Harmful To Your Health... Says Experts!

Experts warn that drinking the recommended eight glasses of water a day could actually be harmful to a person's health

.

Glasgow-based GP Margaret McCartney says benefits of drinking water are often exaggerated by organisations with a vested interest, such as bottled water brands. Writing in the British Medical Journal she also claims that drinking when not thirsty can impair concentration.

A report claims that the benefits of drinking copious amounts of water are quite simply myths, suggesting there is no evidence behind claims that water prevents multiple health problems.

According to Dr McCartney, consumption of excessive amounts of water can in fact lead to loss of sleep and even cause kidney damage instead of preventing it.

Professor Stanley Goldfarb, a metabolism expert from the University of Pennsylvania also claims there is no evidence to suggest that water suppresses appetite.

'If children drank more water rather than getting extra calories from soda, that's good - but there is no evidence that drinking water before meals reduces appetite,' he says.

Around 2.06 billion litres of water was consumed in Britain last year in comparison to just 1.42billion litres in 2000.

Reading the mind of the person is possible!!!Scientists move closer to mind reading

According to TG Daily, Researchers at the University of Western Ontario say they can tell what action a person is planning, moments before they actually do it.

Brain

"This is a considerable step forward in our understanding of how the human brain plans actions," says PhD student Jason Gallivan.

Subjects had their brain activity scanned using functional magnetic resonance imaging (fMRI) while they performed one of three hand movements: grasping the top of an object, grasping the bottom of the object, or simply reaching out and touching the object.

And the team found that by examining the signals from several different brain regions, they could predict, better than chance, which of the actions the volunteer was planning.

"Neuroimaging allows us to look at how action planning unfolds within human brain areas without having to insert electrodes directly into the human brain. This is obviously far less intrusive," explains  professor Jody Culham.

Gallivan says the new findings could also have important clinical implications. "Being able to predict a human's desired movements using brain signals takes us one step closer to using those signals to control prosthetic limbs in movement-impaired patient populations, like those who suffer from spinal cord injuries or locked-in syndrome," he says.

The results are just the latest development in efforts to use fMRI to read peoples' minds. Last summer, UCLA neuroscientists used the same technique to predict whether people would use sunscreen or not.

FMRI has also been used to distinguish between different thoughts, with UCL scientists saying they were able to distinguish which of three short films a volunteer was thinking about.

Makes most of our current privacy concerns look pretty trivial, doesn't it?

Power your laptop by typing!!! watch it it will work!!!

 According to TG Daily, You could soon be able to charge your phone or laptop simply by sending a message, thanks to some nifty work from Australia's RMIT University.

powering Laptop

For the first time, they've been able to characterize the ability of piezoelectric thin films to turn mechanical pressure into electricity, opening the way for self-powered electronics. Simply tapping on the screen, for example to send a text, could produce enough energy to power a device.

Lead co-author Dr Madhu Bhaskaran says the research brings the potential of piezoelectrics - materials that convert pressure into electrical energy - to thin film technology (TFT) microchips.

"Our study focused on thin film coatings because we believe they hold the only practical possibility of integrating piezoelectrics into existing electronic technology," she says.

"The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers - essentially creating an everlasting battery."

The study assessed the energy generation capabilities of piezoelectric thin films at the nanoscale, for the first time precisely measuring the level of power that could be generated.

While the team found that the process currently only generates about a tenth of the power neccessary for a commercial battery, this could be improved in future.

"With the drive for alternative energy solutions, we need to find more efficient ways to power microchips, which are the building blocks of everyday technology like the smarter phone or faster computer," Dr Bhaskaran said.

"The next key challenge will be amplifying the electrical energy generated by the piezoelectric materials to enable them to be integrated into low-cost, compact structures."

SLC result of 2067 have been published!!!Get your result here!!!

The Office of the Controller of Examinations (OCE), Sanothimi, Bhaktapur published the results of the School Leaving Certificate (SLC) exams of the year 2067 (2010/11), Monday. 55.5 percent of the total examinees under the regular category have made it through the exams while 17.3 percent students have passed the exam from the exempted category.

Out of the total 4,56,022 examinees, 220,766 have passed S.L.C under the regular category, which is 8.81 percent less compared to last year’s SLC results. Among them, 20,111 examinees passed with distinction, 82,619 secured first division, 1,07095 secured second and 8,241 students passed in third division.

Similarly, 9,733 students passed under the exempted category of the exams considered the “iron gate” for entering the higher education in Nepal due to low pass percentage every year.

The exams were conducted in March month this year.
