From The New Scientist:

NEUROSCIENCE could do for schools what biomedical research has done for healthcare. That's the conclusion of the Decade of the Mind (DOM) symposium last week in Berlin, Germany, to discuss how the latest findings could be used to improve education.

"In medicine, we have an excellent system in place to go from basic research to clinical practice, while in neuroscience we have the basic understanding of how the brain learns but still need to figure out how to translate this into the classroom," says Manfred Spitzer of the University of Ulm in Germany, one of the conference organisers.

From Cosmos:

SYDNEY: A mathematical equation that counts habitats suitable for alien life could complement the Drake equation, which estimates the probability of finding intelligent alien beings elsewhere in the galaxy.

That equation, developed in 1960 by U.S. astronomer Frank Drake, estimates the probability of intelligent life existing elsewhere in our galaxy by considering the number of stars with planets that could support life (see "Are we alone?").

From New Scientist:

FORGET the risk of exploding rockets or getting sideswiped by a wayward bit of space junk. Radiation may be the biggest hurdle to human exploration beyond low-Earth orbit and could put a damper on a recently proposed mission to Mars orbit.

A panel tasked by the White House with reviewing NASA's human space flight activities (New Scientist, 22 August, p 8) suggests sending astronauts to one of Mars's moons, Phobos or Deimos, among other possibilities raised in its report released last week (http://tinyurl.com/mbajav).

From The Independent:

It sounds too good to be true. But if Indian scientists are correct, hundreds of millions of people across the subcontinent could benefit from a specially-developed strain of rice that "cooks" simply by being soaked in water.

Experts at the Central Rice Research Institute (CRRI) in Orissa who have developed the grain were inspired by so-called soft rice, or komal saul, that grows in the north-east Indian state of Assam. Traditional recipes call for such rice to be soaked overnight in water, then eaten with mustard oil and onions.

Life Was In The Oceans 200m Years Before Oxygen Made Air Fit To Breathe

Life first appeared in our oceans during the Archean eon when the moon was far closer to Earth. The air was too toxic for life on land

From The Daily Mail:

Life existed in the oceans for hundreds of millions of years while the Earth's air was not fit to breathe, research suggested today.

Plant-like bacteria evolved at least 200 million years before oxygen began to build up in the atmosphere, a study has shown.

During this period in its history, known as the Archaean, the Earth was covered by a poisonous smog of methane, ammonia and other toxic gases.
