Submission + - Socially Defeated Males Pass on Stress to Kids (ibtimes.com)

thebchuckster writes: socially defeated males pass on stress to their offspring on a biological level, especially to male offspring. Specifically, they pass on their stress through their behavior in addition to their genetics.

Precopulatory, copulatory, or postcopulatory behavior of defeated male might cause increased female stress perhaps via direct physical aggression/interaction, pheromonal signaling, or ultrasonic vocalization, which could conceivably indicate inferiority or a degree of unfitness.

Submission + - Thousands of Walrus Begin Early Haul-Out in Alaska (livescience.com)

thebchuckster writes: Prompted by receding Arctic sea ice, walruses have begun hauling out on the Alaskan shore by the thousands.

This year, the mass migration began three weeks earlier than last year, with a handful of walruses tagged by the United State Geological Survey heading to shore as early as Aug. 7. Then on Wednesday (Aug. 17), about 8,000 were spotted on or near a beach north of Point Lay, the Associated Press reported.

Submission + - BART Police Site Hacked by a Noob (ibtimes.com)

thebchuckster writes: The daring move wasn't the result of methodical planning from longtime experts. Log files from Internet Relay Chat, a means of online communication that Anonymous favors, shows the attack was carried out by someone with no previous experience.

[08/17/11 11:19] Lamaline_5mg I just got pissed about what bart did and learned a lot about Microsoft SQLi.

Submission + - SPAM: Twitter-Based Hedge Fund is Making Money

thebchuckster writes: Derwent Capital apparently finished its first month of trading in the fund at the end of July, beating the S&P 500, which fell 2.2 percent in July.

Basing the strategy on research published by the University of Manchester and Indiana University in October, the fund operates on the premise that the number of emotional words used on Twitter can be used to predict daily movement in the stock market.

Submission + - Jupiter-sized Alien Planet is Darkest Ever Seen, A (ibtimes.com) 1

thebchuckster writes: The darkest alien world ever spotted by astronomers has been discovered in the outskirts of our galaxy.

"It's darker than the blackest lump of coal, than dark acrylic paint you might paint with. It's bizarre how this huge planet became so absorbent of all the light that hits it," David Kipping, an astronomer at the Harvard-Smithsonian Center for Astrophysics.

Submission + - Fossil 'suggests plesiosaurs did not lay eggs' (bbc.co.uk)

thebchuckster writes: Scientists say they have found the first evidence that giant sea reptiles — which lived at the same time as dinosaurs — gave birth to live young rather than laying eggs.

They say a 78 million-year-old fossil of a pregnant plesiosaur suggests they gave birth to single, large young.

Submission + - Yeast provide clues to evolution of complex life (msn.com)

thebchuckster writes: The budding yeast lives on simple sugars, which it makes by using an enzyme called invertase to chop more complex sugars, like sucrose, into smaller ones, such as glucose and fructose. But because most of these simple sugars escape by diffusing into the surrounding environment, the yeast cell can't consume all the food it makes.

Koschwanez and his team compared the success of single, isolated yeast cells (Saccharomyces cerevisiae) in a low-sucrose solution (table sugar) with that of clumps of yeast cells, formed naturally when the cell walls of the yeast failed to fully separate during cell division. They found that the cells in clumps continued dividing, an indication they were eating well and growing normally, while single cells in the same solution did not divide.

The secret is that the clumped cells happen to help each other out.

Submission + - BBM & Twitter Used as Weapons in UK Riots (ibtimes.com)

thebchuckster writes: Technology Web site TNT is reporting that social media as a tool for rioters is so severe that the digital advisor for London Mayor Boris Johnson is calling for BlackBerry Messenger to be closed down because of the service's role in the riots.

Butcher reportedly described the BlackBerry Messenger service as "text messaging with steroids."

Submission + - Lockheed Martin, NASA set to launch Jupiter Missio (9news.com)

thebchuckster writes: NASA, Lockheed Martin and United Launch Alliance are set to write the next chapter in Colorado's space story with the launch of the 'Juno Mission' to Jupiter.

The $1.1 billion Juno mission will also allow humans to see below Jupiter's dense cloud cover for the first time. It will also capture color images of Jupiter's cloud tops in visible light as a way of engaging the public, who will be involved in helping design which areas of Jupiter should be imaged.

Submission + - Giant African Rat Kills with Poisonous Mohawk (ibtimes.com)

thebchuckster writes: The African crested rat has been known to kill local dogs, but researchers have just figured out how. After eating the "poison-arrow plant," the oversized rodent stores its poison-laced spit in special hollow hairs in its mohawk. Then, when a predator grabs the rat, the animal gets stung with the poison and spit-tipped hairs which can sicken and kill.

Submission + - China Completes Record Submarine Dive (wsj.com)

thebchuckster writes: China's first manned deep-sea submersible completed a Pacific Ocean dive to 5,057 meters (16,591 feet), surpassing current U.S. capabilities and setting a milestone in a race to explore for potentially vast resources in the deepest parts of the world's oceans.

Submission + - Big Wildfires at Yellowstone Every Year by 2050 (ibtimes.com)

thebchuckster writes: Just a few decades ago, the Yellowstone National Park in Wyoming routinely saw no big wildfires in a given year.

However, due to global warming, there will be a big wildfire virtually every single year by 2050 and the area burned will be nearly 400 square miles. By 2075, the area burned is expected to exceed 1,200 square miles. (The entire Yellowstone park spans just under 3,500 square miles.)

Submission + - Large Hadron Collider results excite scientists (bbc.co.uk)

thebchuckster writes: The Large Hadron Collider (LHC) has picked up tantalising fluctuations which might — or might not — be hints of the sought-after Higgs boson particle.

But scientists stress caution over these "excess events", because similar wrinkles have been detected before only to disappear after further analysis.

Either way, if the sub-atomic particle exists it is running out of places to hide.

Submission + - UK AMS Warns Against Mixing Human-Animal DNA (ibtimes.com)

thebchuckster writes: British researchers called for guidelines in experiments that implant human genes or cells in animals, warning of ethical issues in the rapidly developing field of research.

It may sound like something from a horror movie, but inserting a small number of human genes or cells into animals is nothing new.

For example, scientists have already made strides in medical treatment by testing cancer drugs on mice engineered to have human DNA.
