Canadian scientists protest spending cuts

Several hundred Canadian scientists and their supporters held an unprecedented protest march on Tuesday to demonstrate against the government's decision to close down major facilities and fire research staff.

The protesters, who say the right-of-center Conservative government dislikes science, walked through central Ottawa behind a woman dressed as the Grim Reaper and a coffin designed to mourn the "Death of Evidence."

"Evidence is the way that adults navigate reality. To deny evidence is to live in a fairy world ... when countries engage in fantasy it's called state propaganda," Simon Fraser University professor Arne Moores told a crowd of around 800 people gathered on Parliament Hill.

The Conservatives intend to stop funding an Arctic environment atmospheric research laboratory, a move U.S. scientists complain will harm the world's ability to monitor the ozone layer.

Ottawa is also shutting down the Experimental Lakes Area in northern Ontario, which plays a major role in helping study the effects of water pollution. Budget cuts also mean hundreds of scientists and researchers will lose their jobs.

The government ? which will also kill off its own environmental advisory agency ? variously cites the need to save money and focus on more important areas.

"As a country we have been lagging behind our peer nations on applied research and commercialization and our government is taking steps to correct that ? but not at the expense of basic research," said a spokeswoman for Gary Goodyear, junior science minister.

Critics say Ottawa is more interested in helping the powerful energy industry and note the March budget included measures making it easier for major projects such as oil pipelines to receive building permission.

"The government is shutting down science, decimating Environment Canada ... it's pretty transparent," University of Waterloo earth sciences professor Sherry Schiff told Reuters.

Many in the crowd said it was the first time they could remember Canadian scientists demonstrating en masse.

At the end of the protest, some of those present placed flowers at the front of the coffin and science books inside it.

"An iron curtain is being drawn between science and society. Closed curtains, especially those made of iron, make for very dark rooms," said Jeff Hutchings, professor of biology at Dalhousie University in Halifax.

Not everyone sees the issue in this light. A post by a reader on the Canadian Broadcasting Corp's website dismissed the protest as "just more yapping from lefties who have had their year -round holiday collecting loon scat or buffalo farts canceled."

Residents urged to be cautious near Wythall ford as more heavy rain expected

Residents urged to be cautious near Wythall ford as more heavy rain expected

FIREFIGHTERS have been called out to four seperate incidents on a Wythall road in just a few days as motorists have become stuck in a ford because of heavy rain fall.

Firefighters were called out for the forth time to Houndsfield Lane on Sunday morning, at approximately 9.27am, to reports that two adults and two children were stuck in a car in the ford.

A crew from Redditch and a crew from Evesham went to deal with the incident, but found that the car?s occupants had got to safety by the time they arrived.

A fire service spokesman said: ?This is the fourth time we have been called out here in just a matter of days. With more heavy rain expected, we urge people to be particularly cautious in the area.?

Better treatment for brain cancer revealed by new molecular insights

Monday, July 9, 2012

Nearly a third of adults with the most common type of brain cancer develop recurrent, invasive tumors after being treated with a drug called bevacizumab. The molecular underpinnings behind these detrimental effects have now been published by Cell Press in the July issue of Cancer Cell. The findings reveal a new treatment strategy that could reduce tumor invasiveness and improve survival in these drug-resistant patients.

"Understanding how and why these tumors adopt this invasive behavior is critical to being able to prevent this recurrence pattern and maximizing the benefits of bevacizumab," says study author Kan Lu of the University of California, San Francisco (UCSF).

Glioblastoma multiforme (GBM) is the most aggressive type of tumor originating in the brain. GBM tumors express high levels of vascular endothelial growth factor (VEGF), a protein that promotes the growth of new blood vessels that provide nutrients that allow tumors to expand. In 2009, the Food and Drug Administration approved bevacizumab, a VEGF inhibitor, for GBM patients who don't respond to first-line therapies. Although the drug is initially effective, up to 30% of patients develop tumors that infiltrate deep into the brain, making surgery and treatment difficult.

To study how bevacizumab can lead to adverse effects, senior study author Gabriele Bergers of UCSF and her collaborators focused on hepatocyte growth factor (HGF), a protein that controls the growth and movement of cells, because they previously found a link between VEGF and HGF in GBM cells. In the new study, they found that VEGF inhibits the migration of GBM cells by decreasing HGF signaling through its receptor MET. Moreover, tumors were much less invasive?and survival improved?in mice with GBM tumors lacking both VEGF and MET rather than just VEGF alone. The results suggest that MET plays a critical role in GBM invasion when VEGF is blocked.

"These findings provide a rationale for therapeutically combining VEGF and MET inhibition so that patients can benefit from bevacizumab without developing more invasive tumors," Lu says. Because the VEGF and HGF/MET signaling pathways are active in a variety of tumors, this combined treatment strategy may also be applied to other types of cancer.

More charges in murder tied to ?Fast and Furious?

FBI

The Justice Department Monday unveiled new charges against Ivan Soto-Barraza and four others for the murder of Border Patrol Agent Brian Terry.

By NBC News' Pete Williams

Federal prosecutors on Monday revealed more charges in the murder of U.S. Border Patrol Agent Brian Terry.

The indictment, unsealed Monday in Tuscon, Ariz., charges five men with involvement in Terry's death, which is at the center of a controversy over a Bureau of Alcohol, Tobacco and Firearms and Explosives (ATF) gun tracking operation known as "Fast and Furious."


According to the indictment, Manuel Osorio-Arellanes, Jesus Rosario Favela-Astorga, Ivan Soto-Barraza, Heraclio Osorio-Arellanes and Lionel Portillo-Meza are charged with crimes including first degree murder, second degree murder, conspiracy to interfere with commerce by robbery, attempted interference with commerce by robbery, use and carrying a firearm during a crime of violence, assault on a federal officer and possession of a firearm by a prohibited person.??

The 11-count indictment alleges that on Dec. 14, 2010, five of the defendants engaged in a firefight with Border Patrol agents. Terry was shot and killed in the gunfire.

The defendants illegally entered the United States from Mexico to rob drug traffickers of their contraband, according to the indictment.

In addition to the murder of Terry, the indictment also alleges that the five defendants assaulted Border Patrol Agents William Castano, Gabriel Fragoza and Timothy Keller, who were with Terry during the shootout.

A sixth defendant, Rito Osorio-Arellanes, is charged only with conspiracy to interfere with commerce by robbery.

Two of the individuals involved with the shooting are already in custody: Manuel Osorio-Arellanes was arrested on the night of the shooting and Rito Osorio-Arellanes was arrested by Border Patrol agents on December 12, 2010, on immigration charges.

The FBI is offering a reward of up to $1 million for information leading to the arrest of the remaining fugitives.

"We will stop at nothing to bring those responsible for his murder to justice," Attorney General Eric Holder said in a statement.?"Today's announcement reflects the department's unrelenting commitment to finding and arresting the other individuals responsible for this horrific tragedy so that Agent Terry's family, friends and fellow law enforcement agents receive the justice they deserve."

MIPS unveils new Aptiv mobile chip design, vows more speed in a tiny space

Image

MIPS has only had a slight amount of traction in smartphones and tablets given that its best friend is Ainovo. It might get a better footing in an ARM-dominated world with a new range of processors in the Aptiv line. The highest-end chip of the bunch, the ProAptiv, is reportedly much smaller than its ARM opponents across the aisle while managing the same speed, goosing the floating-point math, memory addressing and multi-core support to where it's as much as 75 percent faster over the previous generation. That's good news for mobile devices and set-top boxes where space is tight. MIPS isn't leaving embedded gear like 4G LTE modems alone, either, as the mid-size InterAptiv and tiny MicroAptiv are getting similar improvements. If you're eager to get cracking on a processor of your own, you can license MIPS' new work right away -- and us plebeians who simply buy the devices can expect Aptiv to be ready for gadget use by the middle of the year.
