How UAVs Will Replace The Air Force's Current Fleet

When unmanned aircraft can refuel one another, their time on a mission will be dramatically extended. The Air Force Research Laboratory is spending $49 million over the next four years to create a system that will allow UAVs to autonomously refuel in the air, as seen in this 2007 RQ-4 Global Hawk test.

From Popular Mechanics:

In its latest plans for the future, the Air Force envisions swapping its pilots for a fleet of versatile—and affordable—unmanned airplanes. A single UAV with interchangeable payloads could replace several legacy airplanes. Here's a look at some possible trades.

Well, it looks like Charles Simonyi might have to wait a while for a third trip, because space tourism is going on hiatus. With the shuttle's cancellation leaving Russia as the only country able to service the International Space Station (ISS), the Russian government has announced it will no longer let civilians hitch a ride on Soyuz flights.

From New Scientist:

An infrared space telescope has spotted several very dark asteroids that have been lurking unseen near Earth's orbit. Their obscurity and tilted orbits have kept them hidden from surveys designed to detect things that might hit our planet.

Called the Wide-Field Infrared Survey Explorer (WISE), the new NASA telescope launched on 14 December on a mission to map the entire sky at infrared wavelengths. It began its survey in mid-January.

From Wall Street Journal:

NASA chief Charles Bolden has asked senior managers to draw up an alternate plan for the space agency after members of Congress indicated they wanted to reject a White House proposal to hire private companies to ferry U.S. astronauts into orbit and beyond.

In an internal National Aeronautics and Space Administration memo viewed by The Wall Street Journal, Mr. Bolden ordered officials to map out "what a potential compromise might look like" to satisfy critics on Capitol Hill. By calling for an alternative plan, Mr. Bolden threatened to undercut White House efforts to get its proposed NASA budget through Congress.

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

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 measure would delay the shuttle’s planned retirement in 2010 until NASA is confident that a replacement spacecraft is ready or that the shuttle and its massive payload bay is no longer needed to keep the International Space Station afloat through 2020.

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.

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.
