Thailand – Thai and American researchers announced the development of a vaccine to reduce the risk of contamination by the AIDS virus. This announcement follows the results of a clinical trial conducted on 16,400 people.
This test was conducted by the Ministry of Health of Thailand and the U.S. military. It shows that the vaccine reduces the risk of infection in 32.1% of cases. In their official statement, the researchers suggest that: “This result represents a breakthrough because it is the first time there is evidence that a vaccine against HIV …

Astronomers from the University of Glasgow have reported that they were able to measure the depth of sunspots. Back in 1769 while studying spots on the surface of the solar disk, a professor at the University of Glasgow, Alexander Wilson said that the sun spots appears to be concave.
In their study, the researchers used data collected by the mission SOHO. This device was launched in 1995, specifically for observing the Sun, and it had succeeded in obtaining the large number of photographs of heavenly body during the peak of its …

Sweden – The teams of the Departments of Physiology University of Stockholm and Linköping have successfully created the first artificial nerve cells which can communicate with nerve cells of a man.
Electrical stimulation has long been used to activate nerve signals. Cochlear implants (ie,  surgically implants installed in the inner ear) are an example. This method, if it activates the cells close to the implant, however offers a very average result. Failure to recognize the different types of cells is the cause.

The artificial cell is composed of electrodes inserted in a …

Dust storms on Mars are accompanied by lightning discharges, for the first time revealed signs of electrical discharges on the planet with a new detector that is installed on a terrestrial radio system, Deep Space Networ.
Although scientists have been virtually assured of the existence of lightning on Mars, to detect them using direct observation has not yet succeeded. Only now, the new detector installed on a 34-meter radio telescope, scientists were able to make it clear that Dusty storm on Mars On 8 June 2006 was accompanied by lightning discharges …

France – The team of Joel Drevet, CNRS unit, at the University of Clermont-Ferrand has identified an antioxidant protein (GPx5) that protects the immature sperm as they leave the testicle.
Sperm formed in the testicles, acquire the ability to fertilize in the epididymis, where they complete their maturation. At this stage of maturation, the weakest sperm is subject to an oxidative stress that can damage their DNA. The researchers discovered that the GPx5 protein, produced in the tissues of the epididymis, partly protects the spermatozoa from this stress during their maturation …
