Scientists in Trinity College Dublin (TCD) were celebrating today after the first images of the Sun from the new satellite, Proba 2, were beamed back to Earth. The team of physicists from TCD, led by Dr Peter Gallagher, were responsible for developing novel image processing techniques to enhance and analyse these spectacular new images. The satellite will beam down images of the sun every minute for the next four years in an effort to understand more about solar storms. The images are taken using different wavelengths of light and therefore appear different colour. For more information click here or click here for a recent press release from TCD's physics department.

Foxconn the makers of all Apple iPhones has reportedly received orders for the next iPhone. Omnivision the makers of the current 3.2 MP image sensor in the current iPhone, has apparently also received orders for 5MP image sensors. Also details regarding 32 GB memory and a ‘Digital Compass’ and ‘Touch Sensitive Case’ have been leaked. Unfortunately no details have been released by Apple for their latest offering so all that we can do is speculate. Members of the Mac forums suggest a 1GHz processor, larger resolution screen, 32 GB and 64GB memory, a front facing camera, an OLED screen similar to the new iMac one and maybe a full hardware QWERTY keyboard.
But all we can hope for is a breakthrough device unlike the 3G and 3GS models which were simply revised versions of the original iPhone. Speculated release date is Summer 2010.

Normal sleep is characterized by a general decrease in body temperature, blood pressure, breathing rate, and most other bodily functions. In contrast, the human brain never decreases in activity. Studies have shown that the brain is as active during sleep as it is when awake. Throughout an eight-hour sleep cycle, a normal adult alternates between two very different states, non-REM and REM (Rapid Eye Movement) sleep. Non-REM sleep consists of four stages that range from light dozing to deep sleep. Throughout this state of sleep, muscle activity is still functional, breathing is low, and brain activity is minimal. Approximately 75% of the sleep cycle is spent in non-REM sleep.
Most dreaming takes place during REM (Rapid Eye Movement) sleep. Periodic eyelid fluttering, muscle paralysis, and irregular breathing, body temperature, heart rate, and blood pressure distinguish REM from non-REM sleep stages. REM sleep is also called "paradoxical" sleep because brain wave activity is similar to an awakened state. It is during REM sleep that the brain blocks signals to the muscles to remain immobile so dreams will not be acted out. Adults spend about 20 - 25% of their sleep cycle in REM sleep.
