Moon dust becomes eco hazard to astronauts due to Sun''s elevation

WMoon dust becomes eco hazard to astronauts due to Sun''s elevationashington, April 18 : A new study has revealed that the Moon dust, which causes hazards like ruining scientific experiments and endangering astronauts'' health, is influenced by the Sun''s elevation.

Lunar dust has long been described as the No. 1 environmental hazard on the Moon.

It causes miscellaneous havoc: from destroying scientific equipment deployed on the lunar surface, to creating blinding dust clouds that interfere with lunar landings.

Boredom today may negatively affect marriage in the long term

Boredom today may negatively affect marriage in the long termWashington, April 18 : A new study conducted by Stony Brook University researchers suggests that feeling bored in marriage leads to substantially less marital satisfaction even nine years later.

Research leaders Irene Tsapelas and Arthur Aron, who worked in collaboration with University of Michigan researcher Terri Orbuch, interviewed 123 U. S. married couples seven years into their marriage, and then again, nine years later, 16 years into their marriage.

Gloomy weather ‘sharpens the mind’

Gloomy weather ‘sharpens the mind’New York, Apr 18 : Gloomy weather might leave you feeling blue but it''s great for the brain, claim scientists.

The negative effect that bad weather has on people's mood actually sharpens their mind, researchers from Australia's University of New South Wales School of Psychology claimed.

"People performed much better on our memory test when the weather was unpleasant and they were in a slightly negative mood," The New York Daily News quoted Professor Joe Forgas, who quizzed shoppers at a Sydney store over a period of two months, as saying.

Stay slim to save the planet

Stay slim to save the planetLondon, Apr 18 : Staying slim is not only beneficial for you but it''s also good for the planet, say scientists.

Scientists at the London School of Hygiene and Tropical Medicine''s department of epidemiology and population health say food production is a major contributor to global warming.

The research team suggested that a lean population will consume almost 20 per cent less food than a population in which 40 per cent of people are obese.

Transport-related emissions will also be lower if people are slim because it takes less energy to move them around.

Soon, microwaves that could defuse bombs

microwave22London, Apr 17 : US researchers are designing a laser-guided microwave blaster to destroy explosives.

The weapon, called the Multimode Directed Energy Armament System, could destroy the electronic fuse of an explosive device or missile, such as a roadside bomb, or immobilise a vehicle by disabling its ignition system, reports New Scientist.

It works by creating a plasma channel that acts as a waveguide for the stream of microwaves, and uses a high-power laser to ionise the air.

The project is the brainchild of the US army''s Armament Research, Development and Engineering Centre (ARDEC).

Origin of sulfur in rocks point to oxygen-rich atmosphere 2.4 billion years ago

Origin of sulfur in rocks point to oxygen-rich atmosphere 2.4 billion years agoWashington, April 17: A team of geochemists has come across evidence that Earth''s atmosphere 2.4 billion years ago was oxygen-rich, as pointed out by the origin of sulfur in rocks.

Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere.
