Californian Dolphin Gang Caught Killing Porpoises
Photo: Frustrated youth (Image: Mark P. Cotter)From New Scientist:
SEEMINGLY random acts of violence by bottlenose dolphins on porpoises could be down to sexual frustration among young males.
Cases of the cetaceans killing other creatures for no apparent reason have been reported in UK waters. Now bottlenose dolphins have been seen attacking harbour porpoises in the Pacific Ocean. Crucially, these observations show for the first time that the attackers are young males (Marine Mammal Science, DOI: 10.1111/j.1748-7692.2011.00474.x).

How One Man And Half A Billion Honey Bees Help Feed America
The Beekeeper’s Lament: How One Man and Half a Billion Honey Bees Help Feed America By Hannah Nordhaus HarperCollins 336 ppThe Beekeeper's Lament: How One Man And Half a Billion Honey Bees Help Feed America -- Christian Science Monitor
Our bees are dying in apocalyptic numbers. What does it mean to us?
Bees are amazing. That’s the first reason to read The Beekeeper’s Lament, journalist Hannah Nordhaus’s rewarding account of migratory beekeeping and the mysterious scourge stalking the domestic bee population.
For the past week I’ve been telling everyone I’ve met stories from the miraculous lives of bees, like this one about the queen bee: Dihttp://www.blogger.com/img/blank.gifd you know that she makes only one flight her entire life, when she’s a few days old, and that it’s out among the swarms of male drones where she intertwines with as many as she can before returning to her colony carrying all the sperm she’ll ever need over the course of a reproductive lifetime in which she’ll lay hundreds of thousands of eggs?

Why We Need A Good Night’s Sleep
A Good Night’s Sleep Isn’t a Luxury; It’s a Necessity -- New York Times
In my younger years, I regarded sleep as a necessary evil, nature’s way of thwarting my desire to cram as many activities into a 24-hour day as possible. I frequently flew the red-eye from California, for instance, sailing (or so I thought) through the next day on less than four hours of uncomfortable sleep.
But my neglect was costing me in ways that I did not fully appreciate. My husband called our nights at the ballet and theater “Jane’s most expensive naps.” Eventually we relinquished our subscriptions. Driving, too, was dicey: twice I fell asleep at the wheel, narrowly avoiding disaster. I realize now that I was living in a state of chronic sleep deprivation.

(Credit: Face images courtesy of the Face-Place Database Project, Copyright 2008, Michael J. Tarr)How the Brain Processes Faces: Neural System Responsible for Face Recognition Discovered -- Science Daily
ScienceDaily (June 1, 2011) — Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face.
Until now, scientists believed that only a couple of brain areas mediate facial recognition. However, Carnegie Mellon University's Marlene Behrmann, David Plaut and Adrian Nestor have discovered that an entire network of cortical areas work together to identify faces. Published in the current issue of the Proceedings of the National Academy of Sciences (PNAS), their findings will change the future of neural visual perception research and allow scientists to use this discovery to develop targeted remedies for disorders such as face blindness.

One of the more heated scientific debates of recent years has been stirred up again with the publication of new criticisms of the reported finding of "arsenic life."
The prestigious journal Science published the criticisms today (May 27) along with a defense of the study, which Science had posted online this past December.
A team of researchers led by Felisa Wolfe-Simon of NASA's Astrobiology Institute had studied bacteria collected from California's Mono Lake and reported finding evidence that these microorganisms were substituting the poisonous molecule arsenic for the phosphorous usually used to build DNA.

Analysis of early human-like populations in southern Africa suggests females left their childhood homes, while males stayed at home.
An international team examined tooth samples for metallic traces which can be linked to the geological areas in which individuals grew up.
The conclusion was that while most the males lived and died around the same river valley, the females moved on.
Similar patterns have been observed in chimpanzees, bonobos and modern humans.
Details of the study are published in a letter in Nature.

In Search of Habitable Worlds: The Older the Planet, the Greater Chance There's Life -- Time
To date, the Kepler space telescope has found more than 1,200 likely planets orbiting stars beyond the sun — quite a haul for a satellite that's been flying for just over two years. The true prize Kepler is hunting for, of course, is not just any planet, but one that's a twin of Earth — about the size of our world, orbiting in a zone where the temperature range is like ours. All that would make it a prime place to look for life. Finding such a not-too-hot, not-too-cold world is probably just a matter of time, but even then, there will be one more factor to consider: how old the planet is.

FYI: Why Are Escalators So Dangerous?
Crikey! Hazardous Crocs Getty Images/Washington Post From Popular Science:
The escalator was patented in 1892, and the design hasn’t changed much since then. The landing platforms make entry and exit dicey endeavors—particularly when the moving stairs disappear beneath them, and all manner of clothing and body parts can get stuck. In recent years, escalators have torn the big toe from a Croc-wearing child in Singapore, bucked dozens of riders in Washington, D.C., and strangled a tipsy sushi chef when the hood of his sweatshirt got caught in the gap between the stairs and the landing platform.

New Theory On How The Hawaiian Islands Were/Are Formed

Findings contradict long-held theory that a plume directly fuels Hawaii.
Hawaii's traditional birth story—that the volcanic islands were, and are, fueled by a hot-rock plume running directly to Earth's scorching core—could be toast, a new study hints.
Scientists say they've found solid evidence of a giant mass of hot rock under the seafloor in the region. But it's not a plume running straight from the core to the surface—and it's hundreds of miles west of the nearest Hawaiian island.

My Comment: So much for all of that schooling that I received on how the Hawaiian islands were formed.

(Credit: Gemini Observatory / AURA / Levan, Tanvir, Cucchiara)Cosmic Explosion Is New Candidate For Most Distant Object In The Universe -- Science Daily
ScienceDaily (May 25, 2011) — A gamma-ray burst detected by NASA's Swift satellite in April 2009 has been newly unveiled as a candidate for the most distant object in the universe. At an estimated distance of 13.14 billion light years, the burst lies far beyond any known quasar and could be more distant than any previously known galaxy or gamma-ray burst. Multiple lines of evidence in favor of a record-breaking distance for this burst, known as GRB 090429B for the 29 April 2009 date when it was discovered, are presented in a paper by an international team of astronomers led by former Penn State University graduate student Antonino Cucchiara, now at the University of California, Berkeley.
