A team of archaeologists has captured a snapshot of rural life in the village of Sanyangzhuang in western China during the Han Dynasty, over 2,000 years ago.

Researchers found that the town, though located in a remote section of the Han Dynasty kingdom, appears quite well off. Exploration has revealed tiled roofs, compounds with brick foundations, eight-meter deep wells lined with bricks, toilets, cart and human foot tracks, roads and trees.

There is an abundance of metal tools, including plow shares, as well as grinding stones and coins. Also found have been fossilized impressions of mulberry leaves, which researchers see as a sign of silk cultivation.

Scientists from the University of California, Berekley have captured images of a comet diving into the sun.

Using instruments aboard NASA's twin STEREO spacecraft, the researchers were able to track the comet as it approached the sun and estimate an approximate time and place of impact. STEREO (Solar Terrestrial Relations Observatory) was launched in 2006 and consists of identical spacecraft orbiting the sun, one ahead of Earth and one behind Earth, providing a stereo view of the sun.

After tracking the comet, the team studied data from the ground-based Mauna Loa Solar Observatory in Hawaii, and found images in the predicted spot of what appears to be a comet approaching the edge of the sun from behind the solar disk.

The 9/11/2001 terrorist attacks effected Americans in many ways, even those not directly involved. Now researchers claim that the stress caused by psychological shock from the attacks may have led to an increased number of male children being miscarried in the US.

The authors of a new paper in BMC Public Health found that the fetal death rate for boys spiked in September 2001, and that significantly fewer boys than expected were born in December of that year.

According to the United States Geological Survey (USGS), The Nile Delta Basic holds an estimated 223 trillion cubic feet (tcf) (mean estimate) of undiscovered, technically recoverable natural gas.

This is the first USGS assessment of this basin to identify potentially extractable resources. The USGS also recently completed an assessment of the adjacent Levant Basin Province, with a mean estimated natural gas endowment of 122 tcf.

Bone marrow cells play a critical role in fighting respiratory viruses, making the bone marrow a potential therapeutic target, especially in people with compromised immune systems, say researchers writing in Cell Host&Microbe. They have found that during infections of the respiratory tract, cells produced by the bone marrow are instructed by proteins to migrate to the lungs to help fight infection. The data are published in the current issue of.
