Washington, November 26 : A new set of communication skills is required to improve email interaction, reveals new study.

According to the study authors Daniel A. Menchik and Xiaoli Tian, of the University of Chicago, unlike face-to-face conversations, email interactions tend to ignore tone of voice, body-language and context and can results in creating misunderstandings.

It is to avoid such miscommunication that face-to-face and internet-based contexts each require a set of distinct interaction strategies.

London, Nov 26 : A team of archaeologists has uncovered 2,700 previously unrecorded historic features along the length of Hadrian’s Wall in England, by studying thousands of aerial pictures.

Hadrian’s Wall, in northern England, is a World Heritage Site, built during the rule of the Roman Empire.

According to a report by BBC News, the experts from ‘The English Heritage’ found ancient burial mounds, medieval sheep farms and 19th Century lead mines, among other findings.

For their research, the team was working from more than 30,500 pictures taken during the past 60 years as part of a push to map and interpret archaeological sites across England.

Washington, Nov 26 : Investigation of the fireball that lit up the skies of Alberta and Saskatchewan in the US on November 20 has determined that it was caused by an asteroid fragment weighing approximately 10 tonnes.

The investigation was conducted by University of Calgary researcher Alan Hildebrand, who has outlined a region in western Saskatchewan where chunks of the desk-sized space rock are expected to be found.

The fireball first appeared approximately 80 kilometers above and just east of the border city of Lloydminster, Alberta/Saskatchewan, and traveled SSE towards the Battle River valley, fragmenting spectacularly in a series of explosions.

London, Nov 26 : Reports indicate that the temperature inside India’s first unmanned lunar spacecraft Chandrayaan-1 has gone over 50 degrees Celsius, prompting scientists to explore various options to cool down the unexpected surge.

According to a report by BBC News, scientists say that the problem arose because of very hot temperatures during the lunar orbit.

“Now the moon, our satellite and the sun are in same line this means our craft is receiving 1,200 watts of heat from the moon and 1,300 watts from the sun per meter square,” said M Annadurai, project director of Indian’s moon mission.

If the temperature is not kept in check, many instruments on board the orbiter may fail to perform, according to scientists.
