Details of new Samsung Galaxy S IV leaked 'weeks before launch'

Details of the new Samsung Galaxy S IV phone have been reportedly leaked on the Internet, just weeks before its rumoured launch.

According to the leaks, the new Galaxy smartphone, which is rumoured to be released as soon as March, is set for a major screen upgrade that would make it the most high-definition mobile in the market, the Daily Mail reports.

According to a document which is said to be leaked by a Korean financial services firm, the Galaxy SIV will boast a 5 inch 1920x1080 display, quad-core processor and will run 2 GB of RAM.

The phone will have the latest version of Android Jelly Bean, the document added.

According to other reported leaks, however, the processor will be an ARM-based Qualcomm model equipped, running at 2GHz.

Rumours also claim that the camera in the new phone will feature a rather standard 2MP front-facing CCD and a high definition 13MP rear-facing one capable of shooting HD video in 1080p at 30 frames per second.

Hydrogen sulfide could be next anti-ageing agent

Hydrogen sulfide (H₂S) may play a wide-ranging role in staving off ageing, says a research team from China who has explored the compound’s plethora of potential anti-ageing pathways.

H₂S has been gaining increasing attention as an important endogenous signaling molecule because of its significant effects on the cardiovascular and nervous systems, the team noted.

The evidence is mounting, they said, that hydrogen sulfide slows ageing by inhibiting free-radical reactions, by activating SIRT1, an enzyme believed to be a regulator of lifespan, and probably through its interactions with a gene, klotho, which appears to have its own market basket of anti-ageing activity.

Hydrogen sulfide is produced within the human body, and has a variety of important physiological effects. For example, it relaxes the vascular endothelium and smooth muscle cells, which is important to maintaining clean arteries as one ages, explained first author Zhi-Sheng Jiang, of the University of South China, Hunan.

It functions as an antioxidant. And it inhibits expression of pro-inflammatory factors, all of which “imply an important role in ageing and age-associated diseases,” according to the study.

For example, mice lacking CSE, the gene for an enzyme involved in producing H₂S, manifest extensive, premature arteriosclerosis, an inevitable consequence of ageing, said Jiang.

The gene, klotho, which appears to be upregulated by hydrogen sulfide, is thought to extend lifespan via a number of different pathways, some of which promote production of endogenous antioxidants, according to the their report.

Produced in the kidneys, it has direct angiotensin-converting enzyme (ACE) inhibiting activity; that is, it’s an ACE inhibitor, just like certain drugs that mitigate high blood pressure. Not surprisingly, plasma H₂S declines with age, and is lower in spontaneously hypertensive rats than in those with normal blood pressure. More generally, a lack of H₂S is implicated in cardiovascular disease.

A decline in H₂S is also thought to undermine neurological health. Endogenous H₂S has been found wanting in an animal model of Parkinson’s disease, and is found to be depressed in the brains of patients with Alzheimer’s disease. There are even suggestions, mostly in animal models, but also in human studies, that H₂S may be protective against cancer, according to the report.

“Data available so far strongly suggest that H₂S may become the next potent agent for preventing and ameliorating the symptoms of ageing and age-associated diseases,” concluded Jiang.

In the future, he asserted, people may take H₂S via food, or as an anti-ageing supplement.

The results appeared online ahead of print in the journal Molecular and Cellular Biology.

Can your prenatal diet really help your baby's brain? Yes !! Read it!!!

Can your prenatal diet really help your baby's brain? More and more studies indicate YES! Research from the University of Connecticut (published in the June 2007 issue of American Journal of Clinical Nutrition) reported that infants of women who consumed DHA (a specific type of omega-3 fatty acid) during pregnancy performed better on problem-solving tasks. 

In the study, 29 pregnant women were randomly place into two groups at gestation week 24. One group received cereal bars containing 300 milligrams of DHA each. The second group of women received cereal bars containing no DHA. All study participants ate, on average, five bars each week for the remainder of their pregnancies. When their infants were nine months old, they were tested using the Infant Planning Test and the Fagan Test of Infant Intelligence.

No significant differences in overall intelligence or memory recognition were noted between the two groups. However, the infants of the DHA-eating mothers performed significantly better in problem-solving.

According to these researchers, many pregnant women are not aware that consuming DHA is important during pregnancy and lactation. On top of that, women who are aware of their need for DHA are concerned with finding safe dietary sources of this omega-3 fatty acid. 

Fish and seafood, like salmon, lake trout, sardines, tuna, herring, oysters, shrimp and shellfish are major sources of DHA  for pregnant women .Nuts and seeds, such as walnuts, ground flaxseed, flaxseed oil Canola and soybean oils are also useful food to obtain DHA

Docosahexaenoic acid (DHA) is an omega-3 fatty acid (molecular formula C₂₂H₃₂O_2). In chemical structure, DHA is a carboxylic acid with a 22-carbon chain and six cis double bonds; the first double bond is located at the third carbon from the omega end. Its trivial name is cervonic acid, its systematic name is all-cis-docosa-4,7,10,13,16,19-hexa-enoic acid, and its shorthand name is 22:6(n-3) in the nomenclature of fatty acids.

DHA was also found to inhibit growth of human colon carcinoma cells. DHA concentrations in breast milk range from 0.07% to greater than 1.0% of total fatty acids, with a mean of about 0.34%. DHA levels in breast milk are higher if a mother's diet is high in fish. 

DHA is actively promoted by manufacturers as a food additive. Until recently, sales other than to makers of infant formula have been minimal; however, in 2007, several DHASCO-fortified dairy items (milk, yogurt) began selling in grocery stores.

The peculiar 3D model which allows parents to hold their baby... BEFORE it's even born

Expectant parents who cannot wait to hold their new child can now buy a three-dimensional model of the foetus to cradle and show friends. Japanese inventors have devised a way to transform the commonplace ultrasound scan into an anatomically correct resin replica for parents to handle and keep as a memento. 

The nine-centimetre (3.6-inch) resin model of the white foetus, encased in a transparent block in the shape of the mother's body, is fashioned by a 3D printer after an MRI scan. FASOTEC, the company offering the 'Shape of an Angel' model, even offers parents a miniature version which could be a 'nice adornment to a mobile phone strap or key chain.' Tomohiro Kinoshita, of FASOTEC, said: 'As it is only once in a lifetime that you are pregnant with that child, we received requests for these kind of models from pregnant women who... do not want to forget the feelings and experience of that time.' 

Expectant parents in Japan who can't wait to show the world what their baby will look like can now buy a 3D model of the foetus

The 'Shape of an Angel' costs 100,000 yen (or around £760), and the company said the ideal time for a scan is around eight or nine months into the pregnancy. For those who would like a less pricey version, the company will start offering a 3D model of the face of the foetus at 50,000 yen - £380 - in December. It will use ultrasound images taken at a medical clinic in Tokyo that has forged a tie-up with the company. 

FASOTEC, originally a supplier of devices including 3D printers, uses a layering technique to build up three-dimensional structures. The company also produces 3D models of internal organs that can be used by doctors to plan surgery or by medical students for training, a spokesman said. It is also possible that models can be used in hospitals to better inform patients what their problems are, instead of relying on difficult-to-understand diagrams. 
The technology 'realises not only the form but also texture of the model -- for example making it hard or soft', the firm said . 'By making a model that is similar to a real organ or bone, one can simulate operations and practise different surgical techniques.' 

Kinoshita said the company hit upon the idea of making 3D models of unborn babies in the hope that people would become more aware of the technology. But there are medical benefits too. The company said some medics could also foresee diagnostic possibilities with the models that may help predict difficulties in the birthing process.

Three-dimensional printers have been around for several decades but advances in the technology mean it is now gaining in popularity in several fields. The machines work in a similar way to an inkjet printer, but instead of ink they deposit layers of material on top of each other, gradually building up the product they are making. 

Where traditional manufacturing only becomes efficient with economies of scale because of the need to produce moulds, 3D printing is capable of producing single copies of relatively complicated objects. The technology is not yet advanced enough to build telephones or computers but it is already used to make components.
