Industry Challenges: Drowning In Data

From Technology Review:

The personalized-medicine industry aims to convert information about an individual's genome into useful diagnostic tests and targeted drug treatments. Companies that deal with gathering the information--sequencing genomes and identifying genetic variations--have made impressive technical advances that have dramatically reduced the cost of analyzing DNA (see "Faster Tools to Scrutinize the Genome"). Now the biggest challenge lies in interpreting the huge volume of genetic data being generated. Studies have identified thousands of candidates for genes underlying common diseases, for example, but it's not clear how to make that information medically useful.

First of Missing Primitive Stars Found

The newly discovered red giant star S1020549 dominates this artist's conception. The primitive star contains 6,000 times less heavy elements than our Sun, indicating that it formed very early in the Universe's history. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star's presence supports the theory that our galaxy underwent a "cannibal" phase, growing to its current size by swallowing dwarf galaxies and other galactic building blocks.

From Science Daily:

Science Daily (Mar. 4, 2010) — Astronomers have discovered a relic from the early universe -- a star that may have been among the second generation of stars to form after the Big Bang. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star has a remarkably similar chemical make-up to the Milky Way's oldest stars. Its presence supports the theory that our galaxy underwent a "cannibal" phase, growing to its current size by swallowing dwarf galaxies and other galactic building blocks.

Violent Planet: The Forces That Shape Earth

From Live Science:

Earth is a violent planet, and always has been. In fact it is much calmer today than in the past. As the planet continues to cool – 4.5 billion years after it formed – what was once likely a lava world has become a temperate planet that's two-thirds covered by water and hospitable to life.

But recent events and new research show that the geologic havoc is far from over.

Earth Raised Up Its Magnetic Shield Early, Protecting Water And Emerging Life

From Discover Magazine:

Here we are drinking coffee and tweeting and otherwise going about our lives, generally not giving much thought to the protection that the Earth’s magnetic field affords us from the solar wind. But that magnetic field is crucial for our existence. Now, new findings in Science say that this protective shield originated even 200 million years earlier than scientists had previously thought, perhaps protecting the planet’s water from evaporating away and aiding the rise of life on the early Earth.

Shields Down! Earth's Mag Field May Drop In A Flash

There'll be little warning if Earth's magnetic field flips (Image: NASA/SPL)

From New Scientist:

EVEN if we knew precise details of Earth's core, we would not be able to predict a catastrophic flip in the polarity of its magnetic field more than a decade or two ahead.

Our planet's magnetic field has reversed polarity from time to time throughout its history. Some models suggest that a flip would be completed in a year or two, but if, as others predict, it lasted decades or longer we would be left exposed to space radiation. This could short-circuit satellites, pose a risk to aircraft passengers and play havoc with electrical equipment on the ground.

Why Beer Needs Watering Down

From Times Online:

Brewers are teaming up with environmentalists to help to conserve water supplies — and ensure the pints keep flowing.

It’s enough to make beer drinkers cry into their pints. A combination of factors, including rapid population growth, expanding food needs and unpredictable weather patterns, is heralding a global water crisis. Chronic water shortages are already hitting many regions, particularly in developing countries. Industry, which accounts for about 22 per cent of global fresh water consumption, is increasingly concerned about what will happen when the taps run dry. Brewers are among the most vulnerable: a pint of beer is up to 95 per cent water. Drinkers have been warned that, as water supplies dry up, prices could rise and supplies could be threatened. The battle is on to keep the pumps open.

Tracing King Tut's Family Tree In London

A colossal statue of Amenhotep III - King Tut's only grandfather - can

Tutankhamun has always captured popular imagination, and been a major draw for museums.

The British Museum's 1972 exhibition of artefacts from his tomb smashed all expectations in the box office, drawing over 1.6 million visitors over its nine month duration. The pharaoh nicknamed 'King Tut' has been the source of more speculation, satire and popular culture references than any other male king of Egypt. Last week pathologists announced the results from their studies into the genetic relationship of eleven mummies from the Egyptian New Kingdom (mid 16th to early 11th centuries BC), including those of the legendary pharaoh Tutankhamun.

Shuttle Flights Would Continue Under New Proposal

From The Orlando Sentinel:

WASHINGTON — The space shuttle era could get a new lease on life under a bill filed today by U.S. Sen. Kay Bailey Hutchison, R-Texas.

The 37-page bill also authorizes an additional $1.3 billion in NASA spending next year above President Barack Obama’s request of $19 billion. The extra money would help prepare NASA for as many as two additional shuttle flights per year after 2010, as well as fund new spacecraft development.

Recent news of mammoth icebergs the size of small U.S. states breaking off Antarctica may sound dire. But those events mostly represent business as usual at the world's southernmost continent, scientists say.

A massive iceberg the size of the state of Rhode Island collided with Antarctica's Mertz Glacier in mid-February, and caused a huge new iceberg with an estimated mass of 860 billion metric tons to break off the glacial tongue. Scientists note that such dramatic examples have not been uncommon over the past decade.

Ancient Queen's Burial Chamber Discovered At Saqqara

The Pyramid of Behenu at Saqqara. SCA

From The Independent:

A French archaeological team digging at Saqqara has discovered the burial chamber of 6th Dynasty Queen Behenu, wife of either Pepi I or Pepi II. The burial chamber was revealed while the team was cleaning the sand from Behenu's pyramid in the area of el-Shawaf in South Saqqara, west of the pyramid of King Pepi I.

The burial chamber uncovered by the French mission is badly damaged, apart from two inner walls which contain engraved Pyramid Texts. Those texts were widely used in royal tombs – carved on walls as well as sarcophagi - during the 5th and 6th Dynasties (circa 2465-2150BC).

EVEN the most romantic evolutionary biologist knows that sexual reproduction is rarely a harmonious affair. Among most higher animals it is often predicated on fierce fighting, showy one-upmanship, exploitation and deception. Charles Darwin himself drew the battle lines, when he set out his ideas on sexual selection to explain the evolution of traits that provide mating advantages - either through contests between members of the same sex or by increasing attractiveness to the opposite sex. Much of what Darwin said still guides our thinking. However, since the mid-19th century it has become clear that there is more to successful reproduction than mere copulation.

Why Chile’s Massive Earthquake Could Have Been Much Worse

From Discover Magazine:

Less than two months after the earthquake that shook Haiti, and only hours after a quake causing small tsunamis occurred near Japan, the largest of 2010’s seeming barrage of big seismic events hit Chile. The 8.8 earthquake is the fifth largest since 1900. “We call them great earthquakes. Everybody else calls them horrible,” said USGS geophysicist Ken Hudnut. “There’s only a few in this league” [AP].

According to seismologists, the confluence of earthquakes these last couple months are probably coincidental; they’re all separated by too great a distance to be directly related. However, some say the latest quake is related to the 1960 quake in Chile that remains the largest ever recorded, a 9.5 on the Richter scale.
