Whales in the news
Scientists spot white killer whale off Alaska
That's quite interesting, especially since it seems like it's not a true albino. The other story, however, is even more interesting.
NZ dolphin rescues beached whales
Quite remarkable.

The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease.
Human Papillomavirus (HPV), a virus which causes several types of cancer but is particularly associated with cervical cancer, has developed clever ways of hiding in the body, but researchers at the University of Leeds have found that its ability to trick the body's first line of defence leaves it vulnerable to attack from a second defence system.

You took something that for ever changed the small girl.
Even though she is grown up now, she'll never forget you.
Believe me words, because the little girl was me.

An analysis of six-million-year-old bones from an early human ancestor that lived in what is now Kenya suggests that the species was the earliest known hominin to walk, a new study says.

A production assistant followed Penn around the front of City Hall with a large navy blue umbrella. She held it over his head to shield him from the sun. Seeing he had a captive audience, Penn broke loose of the umbrella to deliver an impromptu speech that Milk would have loved.
"I almost wish Jerry Falwell were alive to see this. Almost," Penn shouted to the crowd. After dropping some names of conservatives who are still with us - "Bill O'Reilly, who is too stupid to talk about," and "Sean Hannity, the butt boy of Rupert Murdoch," Penn said, "We know something more. We know their end is near."

Folkman found a mouse tumor model that mimicked this behavior and in the early 1990s did a series of pioneering experiments. In a strain Lewis lung carcinoma cells of low metastatic potential (LLC-LM), when cells are injected into C57BL/6 mice and allowed to grow subcutaneously, if the tumor is left alone, mice develop only microscopic lung metastases. These metastases do not grow and kill the mouse. If, however, the primary cancer is removed, then many large lung metastases grow rapidly. The results of the experiment above strongly implied that the primary tumor is secreting something that suppresses the growth of microscopic metastases. After this, the Folkman group did what we like to call "brute force" science, collecting mouse urine and analyzing it for tumor suppressive activity until they were able to purify a single 38 kDa peptide, which they designated angiostatin. This involved analyzing literally gallons of mouse urine. (Who said science isn't glamorous?) Once Folkman's group had a bunch of angiostatin on hand, it peformed the following experiment. Two groups of mice were injected with LLC-LM and the tumors allowed to grow to a certain size, after which they were surgically removed. One group was treated with angiostatin, and the control group with saline. The result was that the control group developed massive lung metastases and died, while the group treated with angiostatin had microsocopic lung metastases that never grew beyond a ball of cells. Dr. Folkman then demonstrated that it was the inhibition of angiogenesis by the angiostatin that kept these tumors in check. Ultimately, he used a similar method to discover endostatin, and later he demonstrated that endostatin could induced tumor dormancy in mice. I trust that the reader can see how these seminal preclinical observations about angiogenesis would have been virtually impossible without animal models, given that angiogenesis requires the interaction between tumor cells, cells in blood vessels, and the surrounding tissue stroma to occur.

An exhaustive review of more than 600,000 Iraqi documents that were captured after the 2003 U.S. invasion has found no evidence that Saddam Hussein's regime had any operational links with Osama bin Laden's al Qaida terrorist network.
The Pentagon-sponsored study, scheduled for release later this week, did confirm that Saddam's regime provided some support to other terrorist groups, particularly in the Middle East, U.S. officials told McClatchy. However, his security services were directed primarily against Iraqi exiles, Shiite Muslims, Kurds and others he considered enemies of his regime.

Citing security imperatives, US President George W. Bush announced on Saturday he had vetoed legislation on intelligence funding that called for the CIA to abandon interrogation methods widely seen as torture.
The bill calls for the Central Intelligence Agency (CIA) to question suspected terrorists under the rules of the US Army Field Manual, which forbids the controlled-drowning tactic and other methods widely seen as torture.
"The bill Congress sent me would take away one of the most valuable tools in the war on terror -- the CIA program to detain and question key terrorist leaders and operatives," Bush said in his weekly radio address.

The Vatican has cracked down on feminist interpretations of the liturgy, ruling that God must always be recognised as Our Father.
In a move designed to counter the spread of gender-neutral phrases, the Holy See said that anyone baptised using alternative terms, such as "Creator", "Redeemer" and "Sanctifier" would have to be re-baptised using the traditional ceremony.
The Congregation of the Doctrine of the Faith said yesterday: "These variations arise from so-called feminist theology and are an attempt to avoid using the words Father and Son, which are held to be chauvinistic."
Instead, it said that the traditional form of "Father, Son and Holy Ghost" had to be respected.
The Vatican said anyone baptised under the feminist terms could invalidate their marriage. Cardinal Urbano Navarrete, who wrote a formal commentary on yesterday's ruling, gave warning that anyone who attempted to baptise someone with a gender-neutral form would be penalised. "It is seriously illegitimate and unjust," he said.
Monsignor Antonio Miralles, a professor at the Pontifical Holy Cross University, said the new baptism "subverts faith in the Trinity" because it does not make the relationship between the three persons clear. "God is eternally Father in relation to His only begotten Son, who is not eternally Son except in relation to the Father."
Meanwhile, the Pope also spoke out against gay marriage and abortion before his first trip to the United States before Easter. He praised Americans who respected the "institution of marriage, acknowledged as a stable union between a man and a woman".

White House official who served as President Bush's middleman with conservatives and Christian groups resigned Friday after admitting to plagiarism. Twenty columns he wrote for an Indiana newspaper were determined to have material copied from other sources without attribution.
Timothy Goeglein, who has worked for Bush since 2001, acknowledged that he lifted material from a Dartmouth College publication and presented it as his own work in a column about education for The News-Sentinel in Fort Wayne. The newspaper took a closer look at his other columns and found many more instances of plagiarism.
''The president was disappointed to learn of the matter and he was saddened for Tim and his family,'' White House press secretary Dana Perino said in a statement.
She said Goeglein had accepted responsibility and ''has apologized for not upholding the standards expected by the president.''

Technology served up to young minds by local organizations
Teenagers love technology. In malls, on buses, in school yards, there is hardly a young person who isn't plugged into a cellphone, digital music player or video gadget.
But most young people don't see the connection between science and the technology that they are immersed in, David Yach, chief technology officer for Research In Motion, told school teachers this week during the launch of a Science Superheroes program for teachers.
"Kids don't grasp the link between the science and technology," he said.
Science Superheroes is the newest program of the Business and Education Partnership of Waterloo Region, an organization managed by the Communitech technology association that works to connect educators and students to businesses.
The partnership's program manager, Alayne Hynes, said Science Superheroes involves a series of lectures designed to connect teachers and department heads to "real-life" technology and science experts.
