Even Nazca booby families don't stay together after the kids leave the nest these days. The Nazca booby is a long-lived seabird found in the Galapagos Islands off the coast of Ecuador.
Many Nazca booby females switch mates after successfully raising a chick, according to a Wake Forest University study.
You'll be alone again soon, booby
Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999% of the velocity of light, the maximum speed limit in the Universe.
Quantum entanglement is one of the many non-intuitive features of quantum mechanics. If two photons of light are allowed to properly interact with one another, they can become entangled. One can even directly create pairs of entangled photons using a non-linear process called SPDC (Spontaneous Parametric Down Conversion).
A remarkable new long-necked, gliding reptile discovered in 220 million-year old sediments of eastern north America has been discovered, scientists report. Mecistotrachelos apeoros (meaning "soaring, long-necked") is based on two fossils excavated at the Solite Quarry that straddles the Virginia-North Carolina state line.

The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming.
The potential for gun shows to serve as places where criminals obtain firearms can be curbed through increased regulation without adversely affecting attendance or business, according to a new study.
The study, based on field observations made by Garen J. Wintemute, director of UC Davis’ Violence Prevention Research Program, also found that undocumented gun sales between private parties and illegal “straw purchases” in which a person with a clean record buys a weapon for someone with a criminal record were much more common at gun shows in states with little regulation.
Rome's Mayor Walter Veltroni will officiate at the first public viewing of "Rome Reborn 1.0," a 10-year project based at the University of Virginia and begun at UCLA to use advanced technology to digitally rebuild ancient Rome.
“Rome Reborn 1.0" shows almost the entire city within the 13-mile-long Aurelian Walls as it appeared in A.D. 320. At that time Rome was the multicultural capital of the western world and had reached the peak of its development with an estimated population of one million.Digital video of the Colosseum.

Despite overwhelming military superiority, the world’s most powerful nations failed to achieve their objectives in 39 percent of their military operations since World War II, according to a new University of Georgia study.
The study, by assistant professor Patricia L. Sullivan in the UGA School of Public and International Affairs, explains the circumstances under which more powerful nations are likely to fail and creates a model that allows policymakers to calculate the probability of success in current and future conflicts.
Have you ever been trying to solve a Sudoku puzzle and been gripped by a sinking feeling that maybe you were stuck with a lemon? That maybe the puzzle you are struggling with actually has no solution at all and, if you do find a solution, how can you be sure it's the only one? What if half an hour ago you had written 5 instead of 3---would you then have gone down a path to a completely different solution?
PG-13 films have lots of “happy violence,” say UCLA researchers. Borrowing from the late communications theorist George Gerbner, happy violence is that which is “cool, swift, and painless.” PG-13 films don’t consider the consequences of violent acts, such as injury, death, and the shattered lives of the people involved.
Think you know how to solve global warming? You'll soon get a chance to find out.
A new Web-enhanced version of the most commonly used climate modeling system will allow scientists, students or anyone else to test their theories about the planet's climate. The Community Climate System Model is already used by thousands of scientists, and the results from their models often make headlines around the world.
The new climate modeling TeraGrid service tool was announced Wednesday (June 6) at the annual meeting of TeraGrid users in Madison, Wis.
The Japanese are a polite people. If your host on a trip is Japanese they often make you feel like you are the most important person in the world. Low self esteem? Awe of your culture?
No, they have very high self-esteem and probably feel superior, a study says. Being nice to you may be just another way to prove it.
Organic food is big business these days. Organic fruit and vegetables are hot items because everyone wants to feel like they are eating healthier. What hasn't been studied until now is the impact of organic business on the environment, namely in greenhouse gas emissions from transport.
Researchers of the Group of Recent Prehistory Studies (GEPRAN) of the University of Granada, from the department of Prehistory and Archaeology, have taken an important step to determine how life was in the Iberian Peninsula in the Bronze Age.

Colgate anthropology professor Allan Maca and a team of researchers have found a previously unknown tomb in Copán, Honduras, dating back to the 7th century A.D. that contained the skeleton of an elite member of ancient Maya society in the city.
The unusual characteristics of the tomb’s construction, the human remains, and the artifacts found near the body, according to Maca, paint a picture of an urban state that was more politically complex and culturally diverse than was previously thought.
