Cats may possess the key to developing a vaccine against AIDS

Certain peptides feline immunodeficiency virus to stimulate T lymphocytes ( T-cells) for HIV in humans.

According to a study published in the Journal of Virology conducted by researchers at the University of Florida and University of California San Francisco , a protein of feline immunodeficiency virus is able to produce an effective immune response in human blood infected with human immunodeficiency virus ( HIV).

" In humans , some antimicrobial peptides stimulate immune responses that either do nothing or stimulate HIV infection , while other peptides have anti -HIV activity is lost when the virus changes or mutates to avoid such immunity ," said study author Janet Yamamoto.

According to the academic , some peptides feline immunodeficiency virus work quite well to stimulate T lymphocytes ( T-cells) to fight HIV in humans , so he said he hopes that the feline immunodeficiency virus can be used in the development of an effective vaccine against AIDS

Samsung is preparing a smartphone with curved screen for October

Samsung announced the launch in October of a high-end phone with curved screen, at a time when the world's leading manufacturer of smartphones try to keep the pace of innovation and their supremacy on a fiercely competitive market. The curved screens are an early stage in the evolution of these elements, which are passing or flexible designs that can be folded, which will eventually allow mobile phones and other devices take new forms that could radically change the smartphone market.

"We plan to introduce a 'smartphone' with curved screen in South Korea in October," said the head of strategic business advertising Samsung mobile phone, DJ Lee, in a ceremony held on Wednesday to launch the Galaxy Note Galaxy 3 and the expected Gear, Smart Clock in Seoul. However, the executive gave no details about the features and availability of the device.

Samsung, which has surpassed Apple as the world leader in advanced cell showed in January, at the Consumer Electronics Show held in Las Vegas, prototypes with a flexible screen that could extend from one side.

But technology companies have not managed to figure out how to produce parts on a massive scale in an economical and get panels that can be as thin as a sheet and very resistant to heat.

The curved screens are available commercially in large TVs. South Korean rival Samsung and LG began selling this year curved screens OLED TV for about $ 9,000.

As noted by The Wall Street Journal, some analysts point out that the development of a curved screen would be a first step towards flexible displays. Also launching a smartphone with these features could help evaluate user responses to this technology.

One of the challenges when Samsung to develop a flexible display on a massive scale was to make the display off completely waterproof, the same way they are the traditional glass screens.

Samsung not the only working on the development of technology. LG also seeks to develop flexible displays to incorporate into their devices, explained in April this year.

The Hangover cure may be in the Sprite drink

Chinese scientists tested the effect of 57 different drinks and teas in enzymes that process alcohol in the liver .A team of Chinese scientists Sun Yat -Sen University investigated the effects of 57 different soft drinks and infusions cause in our alcohol -metabolizing enzymes , seeking to

determine which is the most favorable concoction to recover from the hangover (or raw cane , guava , etc. depending on location) .The article was published in the journal Food & Function of the Royal Society of Chemistry. In this, the researchers describe the experiment was to test how the concoctions affect enzymes alcohol dehydrogenase (ADH ) and aldehyde dehydrogenase ( ALDH ) , responsible for metabolizing alcohol in the liver .ADH enzyme is responsible for converting oxidize ethanol to acetaldehyde (or ethanal ) , which is then transformed by the enzyme ALDH acetate .The issue is that acetaldehyde is the main factor for the emergence of a hangover as well as causing various harmful effects on our body , so drink was sought that would enhance more aldehyde dehydrogenase activity , as well as our body would process faster the harmful acetaldehyde.The funny thing was the result: Of all the liquids tested, which showed significantly outperformed the rest were惠 宜 苏打 水and雪碧, better known in the West as the Great Value bottled water (a brand of Wal - Mart) and the drink Sprite, which scientists believe could have components that have the same effect on ALDH that taurine .This does not mean you should spend now to take Sprite with tequila, pisco , vodka , white wine and Fernet , as well as the ingredients vary around the world, scientists clarified that there is still enough to investigate , for example replicate the experiment with people , which is already being planned .

U.S. Army wants an actual Iron Man suit

The soldier user will get night vision, improved strength and body armor .

The U.S. Army commissioned the creation of a " Operator Tactical Assault Suit " ( TALOS for its acronym in English) , something like an Iron Man suit that would give super abilities to view the person as night vision, improved strength and body armor .

Each suit would have an onboard computer capable of responding to specific situations and provide information to the user, the institution said in a statement. In addition, the suit would have temperature sensors body, skin , heart rate and hydration levels, including adjustment systems such as heating , air and oxygen .

The suit could use " liquid armor " , a system that is under development at the Massachusetts Institute of Technology (MIT ) , which has the ability to transform solid minisegundos liquid when an electric current is applied . The idea is that the suit is bulletproof , so that the user can walk between shots without dying.

Human brain discovered 4000 years boiled within his own skull

What may seem like a rock is actually one of the oldest preserved human brains in the world.

A group of archaeologists have discovered a charred brain could be about 4000 years old in western Turkey. What seemed like a simple finding four human skeletons in a burial mound a few years became a source of information that is about to be explored. With this discovery is to investigate about old tumors, bleeding and even the history of some neurological disorders.
Along with the bodies were found other wooden objects. All this, along with skulls and bodies, so burned. According to NewScientist, the conservation hypothesis is that the flames had consumed all the oxygen inside the debris, in addition to "boil" which contained the skull. These actions would be responsible for preventing tissue breakdown.

The last factor that would have helped preserve this brain would be the chemical composition of the soil which are prominent elements potassium, magnesium and aluminum. The reaction of these elements with the human tissue fatty acids form a substance called adipocere, which helps the brain maintain its shape.

Altinoz Meriç Halic University in Istanbul, Turkey along with other colleagues have been responsible for analyzing such discovery. To Altinoz, high tectonic activity in the area would have to do with the fatal situation for these individuals.

"The level of conservation in combination with age is remarkable," said Frank Rühli meanwhile the University of Zurich, Switzerland, who has examined this tissue. "If we want to learn more about the history of neurological disorders, we need to have the tissue in this way," he said finally Rühli.
