Advance In 'Nano-Agriculture:' Tiny Stuff Has Huge Effect On Plant Growth

Tomato seeds exposed to carbon nanotubes (right) sprouted and grew faster than unexposed seeds (left).

From Science Daily:

Science Daily (Oct. 22, 2009) — With potential adverse health and environmental effects often in the news about nanotechnology, scientists in Arkansas are reporting that carbon nanotubes (CNTs) could have beneficial effects in agriculture. Their study, scheduled for the October issue of ACS Nano, found that tomato seeds exposed to CNTs germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other agricultural products, they suggest.

The middle of the world's most remote and inhospitable continent may not seem like an ideal place to conduct complicated scientific research, but this photo shows how the South Pole offers advantages that astronomers and other researchers just can't find anywhere else.

The photo, captured above the new elevated station at Amundsen-Scott South Pole Station in July 2009, is a 20-minute exposure revealing the southern celestial axis — the white cloudy streak is the Milky Way.

From The CNN:

(CNN) -- Hidden under a quaint resort 60 miles northeast of Fairbanks, Alaska, lies a treasure trove of potential energy that's free and available 24/7.

Alaskan entrepreneur Bernie Karl has pioneered modern technology to tap into one of Earth's oldest energy resources: hot water.

Karl, 56, likes to call himself an "imagineer."

Using imagination to fuel his engineering ambitions, this tenacious thinker and self-starter has figured out a way to generate electricity using water that's the temperature of a cup of coffee -- about 165 degrees Fahrenheit.

Darwin Lives! Modern Humans Are Still Evolving

A. Green / Corbis

From Time Magazine:

Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.

A team of scientists led by Yale University evolutionary biologist Stephen Stearns suggests that if the natural selection of fitter traits is no longer driven by survival, perhaps it owes to differences in women's fertility. "Variations in reproductive success still exist among humans, and therefore some traits related to fertility continue to be shaped by natural selection," Stearns says. That is, women who have more children are more likely to pass on certain traits to their progeny.

Naming The Exoplanets

From Technology Review:

The International Astronomical Union is refusing to name the exoplanets. That seems unnecessarily curmudgeonly.

Since 1995, astronomers have found more than 400 planets orbiting other stars. And yet not one of them has a formal name, other than their orginal scientific designation such as MOA-2008-BLG-310-L b, (a sub-Saturnian mass planet recently detected in the Galactic Bulge). How come?

The Internet stands ready to upend the television viewing experience, but exactly how is a matter of considerable dispute.

It should not be so difficult. In an age when nearly all forms of media are digital, where broadband signals course through the industrial world as surely (and as critically) as electricity and freshwater, it should be possible to sit on one’s couch, push a button or two, and call up to your television any form of video-related entertainment you desire.

PORTLAND, OREGON: A shift in Jupiter's orbit early in the life of the Solar System dislodged thousands of rocks from the Asteroid Belt, causing them to hit the inner planets, including Earth.

Evidence for this cataclysmic bombardment comes from a reanalysis of lunar rocks brought back by the Apollo astronauts and a careful study of lunar craters, said David Kring, a planetary geologist at the Lunar and Planetary Institute in Houston, Texas.

Kring presented his findings this week at the Geological Society of America's annual meeting in Portland, USA.

Net Neutrality Is 'Fairness Doctrine For The Internet'

From The Hill:

Marsha Blackburn (R-Tenn.) spoke against net neutrality regulations today at an event put on by the Safe Internet Alliance. Representing the songwriters, singers, actors, producers and other entertainers in Memphis and Nashville, she said the creative community does not want the federal government to interfere with how they are able to get content to consumers via the Internet.

"Net neutrality, as I see it, is the fairness doctrine for the Internet," she said. The creators "fully understand what the fairness doctrine would be when it applies to TV or radio. What they do not want is the federal government policing how they deploy their content over the Internet and they want the ISPs to manage their networks and deploy the content however they have agreed on with ISP. They do not want a czar of the Internet to determine when they can deploy their creativity over the Internet. "They do not want a czar to determine what speeds will be available....We are watching the FCC very closely as it relates to that issue."

The five-year effort may help many wind farm projects that are on hold because of so-called "radar clutter" concerns.

Scientists Find A Precision Clock Logging the Milliseconds Inside Your Brain

Tick Tock Certain neurons in the striatum and prefrontal cortex fire at certain intervals, which MIT researchers have determined to be an internal clock time-stamping sensory experiences for memory just as a digital camera might time-stamp a photo file.

From Popular Science:

Though we do it without thinking, keeping track of time is integral to the brain's function, keeping our senses and our actions ordered in a chronology that we then recall in the form of memory. But important as it is, researchers have never understood the mechanism by which humans index the happenings of everyday life. Now, two macaque monkeys may have helped MIT researchers solve the time tracking puzzle.

On Nov. 27, 2008, Indian police interrogators came face to face with the only gunman captured alive in last year's bloody Mumbai terror attacks. They were surprised by what they saw. Ajmal Kasab, who had murdered dozens in the city's main railway station, stood barely 5 feet tall, with bright eyes and apple cheeks. His boyish looks earned him a nickname among Indians—"the baby-faced killer"—and further spooked a rattled public. "Who or what is he? Dangerous fanatic or exploited innocent?" wondered a horrified columnist in the Times of India. No one, it seems, had expected the face of terror to look so sweet.

From Scientific American:

The International Year of Astronomy marks the 400th anniversary of German astronomer Johannes Kepler's breakthroughs as well as those of his better-known Italian contemporary.

Four hundred years ago this year, two events marked what scientists and historians today regard as the birth of modern astronomy. The first of them, the beginning of Galileo's telescopic observations, has been immortalized by playwrights and authors and widely publicized as the cornerstone anniversary for the International Year of Astronomy. Through his looking glass, the Italian astronomer saw the mountains and valleys of the moon, the satellites of Jupiter, and sunspots—observations that would play a huge role in discrediting the prevailing, church-endorsed view of an Earth-centered cosmos.

Plants can't see or hear, but they can recognize their siblings, and now researchers have found out how: They use chemical signals secreted from their roots, according to a new study.

Back in 2007, Canadian researchers discovered that a common seashore plant, called a sea rocket, can recognize its siblings – plants grown from seeds from the same plant, or mother. They saw that when siblings are grown next to each other in the soil, they "play nice" and don't send out more roots to compete with one another.
