Copiii care stau prea mult la televizor prezinta un risc mai mare de boli cardiace, hipertensiune sau diabet
“Copiii care se uita prea mult la televizor prezinta un risc mai mare de a dezvolta in timp boli cardiace, hipertensiune sau diabet, potrivit unui studiu australian publicat miercuri si citat de AFP.
Copiii studiati, cu varste cuprinse intre 6 si 7 ani, si care petrec prea mult timp in fata televizorului au vasele sanguine din spatele ochilor mai inguste, potrivit cercetarii efectuate de Universitatea din Sydney.
Acest aspect creste in timp riscurile de boli cardiace, hipertensiune si diabet.”
“Sander van Doorn’s massive new single “Koko” recently leaked even though it’s not out officially until Apr. 26th… Remember hearing this explosive cut in his awesome ‘Miami 2011 Aftermovie’ and in his set @ Sensation Norway a few days ago… This beautiful flute-like themed progressive house/trance banger will undoubtedly be one of the biggest anthems on the scene this summer… Check it out NOW!!!!!”
It may just be an elaborate hoax, but a video has surfaced showing the body of an alien found dead in snow in Siberia.
The slender, badly damaged corpse was found lying on a bed of snow with its head to one side and mouth slightly open, the Daily Mail reported.
The video, posted on April 17 on YouTube, has already had over 100,000 views and showed the body of the unidentified “creature”.

Researchers say their findings provide the first genetic evidence that DHEAS can cause common age-related diseases or a decreased lifespan.
Supplements of the steroid have already been commercially available for the past few years.
Dr Guangju Zhai, the study author from King’s College, London, said that while taking it could theoretically slow down the ageing process, it was too early to say for sure how effective it could be.
Before, similar systems only operated over a very limited range and the system had to be designed around a specific frequency bandwidth and amplitude.
The Energy Harvester’s flexibility and adaptability come from the fact that it is able to adjust the resonant frequency of the spring-mass system. It can actually adapt itself to match the motions and vibrations going on around it bv changing its own stiffness.
This provides a couple of key advantages. It is able to make power out of a wide range of motion – be it as tiny as little bumps in the road or as severe as a bone-jarring pothole – and it is not prone to breaking due to excessive shock.
Siemens notes that supply of the piezoelectric ceramics on which the system is based is plentiful. It says its next goal is to determine how to boost the device’s current output and reduce its assembly cost.
Toate aceste ţări au în faţă un lung proces de restaurare a sustenabilităţii fiscale şi a credibilităţii pe pieţe – spune consilierul Rowe. ‘Este, însă, posibil să schimbi cursul economiei cu perseverenţă politică şi socială, aşa cum au făcut-o România, Letonia şi alte ţări lovite de criză’, a explicat el.
THE bones of your middle ear were once part of a mammalian ancestor’s jaw. Now a remarkable Cretaceous fossil provides a snapshot of how this shift took place.
The lower jaws of modern mammals have just one bone: the tooth-bearing dentary. Reptiles, by contrast, also sport smaller bones where the jaw meets the skull. Biologists have long postulated that as mammals evolved, the smaller, post-dentary bones shrank to form the tiny bones of the middle ear.
Fossils of ancient mammals such as Morganucodon hint at this: the post-dentary bones are still attached to the dentary, and are used for both hearing and feeding. What happened next had been left to best guesses.
Now Liaoconodon hui, discovered in China by Jin Meng of the American Museum of Natural History in New York, has filled the gap. “It is the first unambiguous evidence showing that transitional stage,” says Meng. The 120-million-year-old mammal, about the size of a large rat, was a close relative of early mammals. Of interest is a bridge called Meckel’s cartilage, which connects the small bones to the jaw (see diagram).
Living mammals, including humans, have Meckel’s cartilage as embryos, but it disappears as they mature. In the L. hui fossil – an adult – it is ossified and the fossil shows how it supported some of the post-dentary bones as they shifted into the ear (Nature, DOI: 10.1038/nature09921).
The researchers found a striking 94 per cent similarity in the biochemistry between the two brains, and discovered that at least 82 per cent of all human genes are expressed in the brain.
Allan says this isn’t too surprising:
When you think about the complexity of the functions of the brain, and the variety of different cell types found within the brain, it’s not quite as surprising to see how much of the genome is used to serve the brain
Both brains used in the $55 million project were male, which prompted The Wall Street Journal to ask why a woman’s brain had not been included. Allan told Bloomberg that eligible brain donors usually die from accidental causes or cardiac arrest, both of which disproportionately affect men. However, he says the project is currently processing a female brain, and that ultimately, the facility will run at least 10 brains through the process.
Other researchers are also attempting to map neural connections in a mouse brain, something MRI cannot do. They will turn slices of brain into digital images by an automated electron microscope. A computer will read those images, trace the outlines of nerve cells, and stack the pictures into a 3D reconstruction.
Maps like these have limitless potential in drug discovery and human genetics and will no doubt be an essential step forward in the fight against disease.
Instead of objects popping out at you like regular 3D, we see things going inwards instead. Words aren’t going to do justice to how amazing it looks, so hit the break to check out a video demonstration:
Walter Bruening, cel mai batran barbat din lume, a murit la varsta de 114 ani, la spitalul din Great Falls, Montana (nord-vestul Statelor Unite), anunta AFP, citand presa locala. Intr-un interviu acordat in urma cu 2 ani publicatiei locale Great Falls Tribune, Walter Bruening marturisea ca secretul longevitatii sale este acela ca si-a acordat doar cate doua pauze de relaxare pe zi, de-a lungul vietii.
“Obisnuiesc sa nu mananc seara, este o senzatie fantastica. Ar trebui sa li se spuna oamenilor sa nu manance tarziu”, mai spunea el.
“People who are ridiculed for saying that earthquakes are a result of global warming could actually be right, scientists claim.
Long-term climate change has the potential to spin Earth’s tectonic plates, according to a news study from the Australian National University.
Working with researchers in Germany and France, they have established a link between the motion of the Indian plate over the last ten million years and the intensification of Indian monsoons.”
“Every language in the world – from English to Mandarin – evolved from a prehistoric ‘mother tongue’ first spoken in Africa tens of thousands of years ago, a new study reveals.
After analysing more than 500 languages, Dr Quentin Atkinson found compelling evidence that they can be traced back to a long-forgotten dialect spoken by our Stone Age ancestors.
The findings don’t just pinpoint the origin of language to Africa – they also show that speech evolved at least 100,000 years ago, far earlier than previously thought.”
