Killer Whales Die Without King Salmon

King Salmon: It's What's for Dinner. A killer whale snags a king salmon. Some killer whale populations favor king salmon so much that the whales will actually die when numbers of this largest member of the salmon family drop. Brian Gisborne

From Discovery News:

Sept. 16, 2009 -- Some killer whale populations favor king salmon so much that the whales will actually die when numbers of this largest member of the salmon family drop, according to new research.

The study, published in the latest Royal Society Biology Letters, suggests that although killer whales may consume a variety of fish species and mammals, many are highly specialized hunters dependent on this single salmon species.

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).

The Science of Hunger: What 1 Billion People Feel

From Live Science:

Despite a record level of people suffering from hunger, food aid is at a 20-year low due to the poor global economy, United Nations officials said today. The result: More than 1 billion people across the world will face hunger this year.

"For the world's most vulnerable, the perfect storm is hitting with a vengeance," said U.N. World Food Program (WFP) Executive Director Josette Sheeran. So far this year, the agency has received less than half of the $6.7 billion it needs to feed 108 million people in 74 countries, Sheeran said.

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.

Direct Evidence Of Role Of Sleep In Memory Formation Is Uncovered

For the first time, researchers have pinpointed the mechanism that takes place during sleep that causes learning and memory formation to occur. (Credit: iStockphoto/Mads Abildgaard)

From Science Daily:

ScienceDaily (Sep. 16, 2009) — A Rutgers University, Newark and Collége de France, Paris research team has pinpointed for the first time the mechanism that takes place during sleep that causes learning and memory formation to occur.

It’s been known for more than a century that sleep somehow is important for learning and memory. Sigmund Freud further suspected that what we learned during the day was “rehearsed” by the brain during dreaming, allowing memories to form. And while much recent research has focused on the correlative links between the hippocampus and memory consolidation, what had not been identified was the specific processes that cause long-term memories to form.

British Skeleton Suggests Ancient Murder Mystery

A skeleton from ancient Roman times, found in the buried town of Venta Icenorum in Norfolk, England is buried on its side. Romans laid bodies out properly, however, suggesting this man might have met a murderous end. Credit: University of Nottingham.

From Live Science:

A skeleton found at an ancient Roman site in Britain has researchers wondering if they've stumbled on a murder mystery.

Excavations at the buried town of Venta Icenorum at Caistor St. Edmund in Norfolk, England, found what, for now, archaeologists are terming a "highly unusual" setup.

"This is an abnormal burial," said archaeologist Will Bowden of the University of Nottingham. "The body, which is probably male, was placed in a shallow pit on its side, as opposed to being laid out properly. This is not the care Romans normally accorded to their dead. It could be that the person was murdered or executed, although this is still a matter of speculation."

The skeleton has been removed for further investigation.
