From Science Daily:

Scientists have shown that the main shoot dominates a plant’s growth principally because it was there first, rather than due to its position at the top of the plant.

Collaborating teams from the University of York in the UK and the University of Calgary in Canada combined their expertise in molecular genetics and computational modelling to make a significant discovery that helps explain why pruning encourages plants to thrive.

SAN FRANCISCO — Moore’s Law coming to an end? Not if you ask Intel, which announced Tuesday that it plans to offer chips based on a 22 nanometer process technology in the second half of 2011.

The 22nm chip packs in more than 2.9 billion transistors into an area the size of a fingernail. That’s double the density of the 32nm chips that are currently the cutting edge; most of Intel’s CPUs today are still based on a 45nm process.

A company is preparing human trials of a DNA-based, universal influenza vaccine.

The first doses of H1N1 flu (swine flu) vaccine are due to be shipped to hospitals around the country in the next few weeks--seven months after the virus strain was first identified. These vaccine doses will use either inactivated or weakened live viruses to prompt immunity--an approach that can fail if any of the live viruses is strong enough to replicate, or if the inactivated viruses have been killed beyond all immune recognition.

Stunning Pictures Of Glaciers From Space Reveal Worrying Signs Earth's Ice Is Melting Away

Grey Glacier in Chile: The ice field covered 104 square miles in 1996. This 2007 picture from the International Space Station revealed it had dramatically receded. Scientists think increased regional temperatures has reduced the amount of ice being replenished each year

From The Daily Mail:

These awe-inspiring images of glaciers are helping scientists to determine just how quickly our planet is heating up. The huge ice fields are thought to be one of the most reliable indicators of climate change and are best studied from space.

The features form when snow accumulates on an area of land over tens to hundreds of years. It eventually becomes so thick and heavy that it forms dense glacial ice. When enough ice is compacted it beings to flow downhill or spread across flat land.

The first day of autumn — Sept. 22 this year — is no guarantee of fall-like weather, but officially the season's start comes around at the same time each year nonetheless.

Well, sort of.

The first day of autumn arrives on varying dates in different years for two reasons: Our year is not exactly an even number of days; and Earth's slightly noncircular orbit, plus the gravitational tug of the other planets, constantly changes our planet's orientation to the sun from year to year.

From New Scientist:

THEY might be bald and ugly, but naked mole rats never get cancer. If their trick can be copied it could help humans resist cancer too.

It's almost impossible to culture naked mole rat cells in the lab, which made Andrei Seluanov and Vera Gorbunova from Rochester University, New York, wonder if this might be linked to their ability to resist cancer.

They found that a dilute solution of naked mole rat skin cells did start to proliferate, but stopped once the cells reached a certain, relatively low density. Such "contact inhibition" is also used by human cells to inhibit growth, but cancer bypasses this mechanism so cells keep growing.

A Robot That Juggles Blind

Pendulum Juggler from Philipp Reist on Vimeo.

From Popular Science:

This machine uses no sensors, no feedback -- just the power of math -- to do its tricks.

In theory, designing a robot that continuously juggles a single ball should not be difficult. Calibrating the machine would be a pain but once you got the thing running, it should continue to juggle the ball until some variable intervenes. In a perfect world, this would occur elegantly, but here on Earth things just don't come off so beautifully. However, through some smart design and precise math, researchers at the Swiss Federal Institute of Technology in Zurich have created the Blind Juggler, so named because it juggles a ball continuously, even when variables are introduced, without the use of sensors.

As soon as he walks in, the ritual can begin: family members take their seats around the table (he sits at the head, of course) and dinner is served. Our couple are reliving a scene that has played out billions of times in our history because gender roles — husband at work all day, woman as homebody — have been forged not by relatively recent social conventions but by our distant evolutionary past.

WHO: H1N1 Vaccine Production To Fall Short

From Time Magazine:

(GENEVA) — Global production of swine flu vaccines will be "substantially less" than the previous maximum forecast of 94 million doses a week, the World Health Organization said Friday.

The number of doses produced in a year will therefore fall short of the 4.9 billion doses the global health body previously hoped could be available for the pandemic, WHO spokesman Gregory Hartl told reporters in Geneva.

Production will be lower because some manufacturers are still turning out vaccines for seasonal flu — an illness that can be serious in sick and elderly people, Hartl said.
