The remains of a huge underwater city off the western coast of India may force historians and archaeologists to radically reconsider their view of ancient human history. It?s believed that the area was submerged when ice caps melted at the end of the last ice age, 9-10,000 years ago.

Marine scientists say archaeological remains discovered 120 feet underwater in the Gulf of Cambay off the western coast of India could be over 9,000 years old. The vast city – which is five miles long and two miles wide – is believed to predate the oldest known remains in the subcontinent by more than 5,000 years.

The West Antarctic Ice Sheet is still dropping huge chunks of iceberg that drift hundreds of miles while they slowly melt, but it may have stopped melting, meaning that there will not be a rise in ocean levels in the immediate future. NASA?s Jet Propulsion Laboratory and the California Institute of Technology say their measurements show the ice sheet is getting thicker. ?We find strong evidence for ice-sheet growth,? say Ian Joughlin and Slawek Tulaczyk. Other scientists have been taking measurements showing the ice sheet, known to scientists as the WAIS, has been steadily melting since the end of the last Ice Age about 11,000 years ago.

Solar activity reaches its height every 11 years, when solar flare erupt solar flares erupt near sunspots daily. Coronal mass ejections, composed of billion-ton clouds of magnetized gas, fly away from the Sun and hit the surrounding planets. The Sun?s magnetic field, which is as large as the solar system itself, becomes unstable and reverses. This is known as a Solar Max. The most recent Solar Max reached its height in mid-2000. Sunspot counts were higher than they had been in 10 years, and solar activity was intense. One eruption on July 14, 2000 caused brilliant auroras as far south as Texas, along with electrical brown-outs. It temporarily disabled some satellites.

Harvard AIDS researchers working with monkeys say the virus overcame an experimental vaccine by changing a single gene, killing one of the 8 animals being tested. This disappointment doesn?t mean that AIDS vaccines are doomed to fail, but it illustrates how hard it will be to produce one.

HIV is already is known to mutate and become resistant to standard AIDS drugs in at least half of all Americans who have the infection. Now researchers have seen a similar outcome with an experimental vaccine that tries to stimulate immune cells to prevent the virus from multiplying.
