''Super-tomatoes'' may help keep cancer at bay

London, Oct 26 : British scientists have developed purple-coloured tomatoes that may protect against cancer.

The research team from John Innes Centre has created tomatoes genetically modified to produce antioxidants that may help keep cancer at bay.

The plant was created by introducing the genes from the snapdragon, a garden flower that allows them to produce a type of nutrient that prevents cancer.

When these tomatoes were fed to mice genetically engineered to have cancer the animals'' lifespans were significantly extended.

The researchers hope that the "super-tomato" could help people meet the government''s recommendation that everyone should eat five portions of fruit and vegetables a day.

Why life on Earth coincides with a vital shift in the makeup of the universe

Canberra, Oct 26: Scientists have come up with an answer to the puzzling question of why life on Earth coincides with a momentous shift in the makeup of the universe.

According to a report by ABC News, research into finding an answer to this mystery was done by Ph. D. student Chas Egan and Charley Lineweaver from Australian National University.

The conundrum has its roots in the way the universe changes as it expands, explained Egan.

Soon after the Big Bang, some 14 billion years ago, most of the energy in the universe was in the form of heat. Later, as the universe cooled and expanded, matter, such as stars and planets, became dominant.

Creeping changes underground may warn of impending earthquakes

Creeping changes underground may warn of impending earthquakesWashington, Oct 26 : A team of scientists may have discovered some hidden clues that may help them identify impending earthquakes, in the form of a multitude of creeping changes underground.

Detecting and interpreting these changes would help forecast earthquakes, but that detection has proven difficult, partly because scientists don’t yet fully understand the complex chain of events that precipitates a quake.

Now, a team of researchers has claimed to find hidden clues that can help them predict looming quakes.

International project to track light pollution in atmosphere

Canberra, Oct 26 : Amateur astronomers are collaborating on an international project to track urban light pollution in the atmosphere, which clouds our view of the stars.

As urban light pollution grows as a problem, a global survey aims to map its spread, with the help of amateur star gazers.

According to a report in Cosmos magazine, the project is known as the Great World Wide Star Count, which pools skyward observations taken by citizens around the world.

The information helps scientists measure the extent to which city lights mask the visibility of stars.

Archaeologists find 1,700 year old Iron Age wooden artifacts in Sweden

Stockholm, Oct 26 : A team of archaeologists digging near the planned expansion of a roadway in Sweden have uncovered 1,700 year old artifacts made of wood, making them some of the oldest man-made wooden objects over discovered in the country.

According to a report in The Local, the find was made near Alvangen in western Sweden and provides additional clues about how farmers in the region lived during the Iron Age.

“We’ve found hundreds of wooden objects, including a wooden wheel. We’re coming much closer to the people of the Iron Age with this find. We’re really getting up close and personal,” said Bengt Nordqvist, an archaeologist from the Swedish National Heritage Board.

Simulated seismic signals could help save lives during volcanic eruption

Washington, Oct 26 : Scientists have simulated the seismic signals that precede a volcanic eruption for the first time and created a 3-D visualization of those warning signs under controlled conditions, which could help save lives in case of an actual catastrophe.

According to a report in Newswise, the simulation has been made by an international team working out of the University of Toronto’s (U of T’s) Rock Fracture Dynamics Facility in Canada.

By performing tests on basalt rock from Sicily’s still-active volcano Mt. Etna, the team was able to record the seismic waves generated during the earthquakes that occur before volcanic eruptions.
