From New Scientist:

It has been a whipping boy for its critics, but NASA's Ares I rocket has received a rare boost.

Despite budget and technical concerns, NASA's Aerospace Safety Advisory Panel (ASAP) believes Ares I is the best bet for flying astronauts to the International Space Station after the space shuttle retires, because it has been designed from the outset with the safety of its crew in mind.

Siblings As Important As Parents In Child’s Behaviour

From The Telegraph:

Children can learn as much from their brothers and sisters as they do from their parents, new research suggests.

The influence siblings have on each has a considerable impact on a child's development and shouldn't be underestimated, say scientists.

While parents are better role models in formal settings, such as table manners, siblings have more influence in how kids behave 'on the street', the researchers say.

Science Daily (Jan. 18, 2010) — A new study examines how ice sheets, such as the West Antarctic Ice Sheet, could become unstable as the world warms.

The team from Oxford University and Cambridge University developed a model to explore how changes in the 'grounding line' -- where an ice sheet floats free from its base of rock or sediment -- could lead to the disintegration of ice sheets and result in a significant rise in global sea level.

In the next years up to ten of these high-tech instruments will take measurements to better understand many processes in the oceans. Currently scientists and technicians prepare the devices for their first mission as a 'swarm' in the tropical Atlantic.

Astronauts experience weightlessness, and most of them also lose weight in space. Why? Because they are often nauseous, always busy, and the food on board their capsules, shuttles and space stations doesn't look, smell or taste like it does on Earth.

As a result, NASA has devoted years to creating foods that can travel safely into space and meet astronauts' nutritional needs while not making a mess of their spacecraft.

It is one of the most famous anecdotes in the history of science. The young Isaac Newton is sitting in his garden when an apple falls on his head and, in a stroke of brilliant insight, he suddenly comes up with his theory of gravity. The story is almost certainly embellished, both by Newton and the generations of storytellers who came after him. But from today anyone with access to the internet can see for themselves the first-hand account of how a falling apple inspired the understanding of gravitational force.

For autonomous robots, this can be a bit of a problem, since they may have to accommodate changing terrain in real time or risk getting stuck or losing their balance.

A central claim was the world's glaciers were melting so fast that those in the Himalayas could vanish by 2035.

Another Sign That America's Science Position In The World Is Changing

U.S. Keeps Science Lead, But Other Countries Gain -- Wall Street Journal

The U.S. remains the world's science and technology leader, but other countries are gaining ground, the National Science Board said Friday in its biennial report on science and engineering.

The U.S. accounted for nearly a third of $1.1 trillion spent on research and development globally in 2007, minted more science and engineering doctorates than any other country, and led the world in innovative activity. Efforts by China and other developing Asian countries to boost their science and engineering capabilities are bearing fruit, however, and the gap between them and the U.S., though still wide, is narrowing.
